Bind Variables in a insert

I want to use a bind variable in order to insert a binary data in a raw field.
I do this in a C# app., using parameters, in Oracle Server it works successfully
but when I change the conection to a Oracle Lite Data Base the bd returns
the error "37000[POL-5228]: Syntaxis Error".
The sql is like this: "insert into GENERIC_TABLE (id, data) values ("+id.ToString()+", :Data)"
And after I insert the parameter.
Does someone know if in Lite the bind variables syntaxis is diferent?
Could you help me? What's happend in lite version?
Thanks in advance

Hi,
As far I know, SQL Statements, metadata, user names, etc... in fact every string that is not binded or defined can only be ANSI or UTF16.

Inserting a LINESTRING with a bind variable

Hello - I am trying to insert a LINESTRING with a bind variable. Here is my query that works:
INSERT INTO EDGE (pts)
VALUES (SDO_GEOMETRY('LINESTRING(-71.110157 42.513495, -71.110159 42.51359)',8307));
But if I want to pass in the pts as a bind variable, as follows:
INSERT INTO EDGE (pts)
VALUES (SDO_GEOMETRY(LINESTRING(:pts),8307));
When prompted in sqlDeveloper I set the bind variable to: -71.110157 42.513495, -71.110159 42.51359
I get the following error: PLS-306: wrong number of types of arguments.
Thanks!

Thanks - Your reply worked well, but I ran into another snag. If the linestring is greater than 4000 chars, I get another error.

Oracle bind variable

Can i use an item which type is image as bind variable in the insert statement?
When i pass image item of oracle form as a bind variable in the insert statement then "Bad bind variable error" occurs.
Please help me.
- ashraf

Hello,
No, you cannot. If the image item points to a database BLOB column, Forms will store the image in this column at commit time.

How to update bind variable and restrict values in a Model Driven LOV?

Hi Guys,
Using JDev 11.1.1.2.0
I've recreated an excellent Frank Nimphius article about restricting values derived from a model driven LOV (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/44-restrict-lov-169186.pdf)
But my bind variable isn't updating. Deleting the bind variable gets me the entire LOV. Activate the code below and insert a bind variable into the where clause like Frank says and I get nothing back. Bind variable is blank. Any ideas? Code wasn't supplied with the article. It seems simple enough but the bind variable isn't updating in the SQL, even though the updated value shows up here...
public void onLovLaunch(LaunchPopupEvent launchPopupEvent)
    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    FacesCtrlLOVBinding lov = (FacesCtrlLOVBinding)bindings.get("DepartmentId");
    lov.getListIterBinding().getViewObject().setNamedWhereClauseParam("deptId","60");
    System.out.println("lov name: " + lov.getName().toString());
    System.out.println("lov Param Attrs: " + lov.getListIterBinding().getViewObject().getNamedWhereClauseParams().getAttribute("deptId").toString());
    System.out.println("lov View Object: " + lov.getListIterBinding().getViewObject().getName().toString());
    System.out.println("lov IterBinding: " + lov.getListIterBinding().getName().toString());
   }Gets me ...
lov name: DepartmentId
lov Param Attrs: 60
lov View Object: _LOCAL_VIEW_USAGE_lov_model_queries_EmployeesView_DepartmentsView
lov IterBinding: DepartmentIdList_2

That's a good idea, but it's still not working. Here is how I implemented it. It might be different from your suggestion as I'm still pretty new to this.
I have a recursive tree table. You select a node. You then click a button which calls the listener below. "findParents" is a method call to the AppModuleImpl class and it finds all parent nodes of your selection. "restrictPartBomLOV", also of the AppModuleImpl class, then modifies the model driven lists' View Object (partBomLOV) to exclude those parent node values.
The resulting model driven LOV on the popup should be updated, yeah? But it still isn't udpating. If I manually type in the updated Where clause in PartBomLOV.xml query tab, it works, but it doesn't programmatically.
public void insertPopupFetchListener(PopupFetchEvent popupFetchEvent)
    BindingContainer bindings = getBindings();
    OperationBinding operationBinding = bindings.getOperationBinding("findParents");
    parents = (List)operationBinding.execute();
    operationBinding = bindings.getOperationBinding("restrictPartBomLOV");
    operationBinding.execute();
   public void restrictPartBomLOV(List parents)
      ViewObjectImpl vo = getPartBomLOV();
      String wcl = "";
      Object[]   p = parents.toArray();
      for(int i = 0; i < p.length; i++)
         if (i == 0)
            wcl = wcl + "PNUM <> '" + p.toString() + "'";
else
wcl = wcl + "AND PNUM <> '" + p[i].toString() + "'";
vo.setWhereClause(wcl);
System.out.println(vo.getWhereClause().toString());
vo.executeQuery();

Can Oracle convert literals to bind variables?

Good morning everyone.
I have a procedure similar to this in our database:
    FUNCTION Get_Tag_Element_Id_For_Set(Element_Attr_Id_Table_In   in    ATTRIBUTE_TABLE_ID_TAB) RETURN NUMBER IS
      v_Select_Statement                    VARCHAR2(32767);
      v_Element_Id                             ELEMENT.Element_Id%TYPE;
    BEGIN
      FOR I IN 1..Element_Attr_Id_Table_In.COUNT LOOP
        IF v_Select_Statement IS NULL THEN
          v_Select_Statement := 'SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Element_Attribute_Id = ' || Element_Attr_Id_Tab_In(i);
        ELSE
          v_Select_Statement := v_Select_Statement || ' intersect ' ||
                                'SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Element_Attribute_Id = ' || Element_Attr_Id_Table_In(i);
        END IF;
      END LOOP;
      EXECUTE IMMEDIATE v_Select_Statement INTO v_Element_id;
      RETURN v_Element_Id;
    END;What this does is to create a query similar to this:
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 1 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 2 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 3 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 4 intersect
SELECT distinct Element_Id FROM ELEMENT_ATTRIBUTE_MANY_2_MANY WHERE Tag_Element_Attribute_Id = 5;
I am using Dynamic SQL because the number of intersect pieces can vary from 1 to 15 and in the future it can grow.
The problem that I have is that because the literals are part of the string, the query is being hard parsed every single time. In our production environment this means 100s of thousands of times per day which according to our DBA has added 15% plus to our average load. I know that I can come up with a rewrite to avoid this, but I was wondering if there is a parameter I can set at the session or at the database level where the database itself can convert this kind of query into one with bind variables.
Thanks,
Tom

Basically I have an XML document.
The document has ELEMENTS.
ELEMENTS can have attributes.
There is a many to many relationship between ELEMENT and ATTRIBUTES so I have a XREF table to represent this relationship.
When I receive a new document, I need to determine if a group of ATTRIBUTES already exist together in the XREF table so I have to find their common ELEMENT_ID or NULL in which case I would create a new ELEMENT and associate the new set of attributes to the new ELEMENT.
Since the number of attributes can vary from 1 to around 15 for now, I had to dynamically build the query that find the common ID(intersect) if it exists.
Here is some DDL and inserts:
CREATE TABLE ELEMENT(ELEMENT_ID NUMBER NOT NULL);
CREATE TABLE ELEMENT_ELEMENT_ATTRIBUTE_XREF(Element_Id NUMBER NOT NULL, Element_Attribute_Id NUMBER NOT NULL);
ALTER TABLE ELEMENT_ELEMENT_ATTRIBUTE_XREF ADD CONSTRAINT ELEMENT_ATTR_MANY_2_MANY_PK PRIMARY KEY(Element_Id, Element_Attribute_Id);
ALTER TABLE ELEMENT ADD CONSTRAINT ELEMENT_PK PRIMARY KEY(Element_Id);
INSERT INTO ELEMENT VALUES(1);
INSERT INTO ELEMENT VALUES(2);
INSERT INTO ELEMENT VALUES(3);
INSERT INTO ELEMENT VALUES(4);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(1, 1);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(1, 2);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(2, 1);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 1);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 3);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 4);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(3, 5);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(4, 6);
INSERT INTO ELEMENT_ELEMENT_ATTRIBUTE_XREF VALUES(4, 7);
So for instance if I passed an array (Attribute ID Tab) containing ELEMENT_ATTRIBUTE_ID list 6 and 7 I would get 4 as the answer.
Hope this helps,
Thanks,
TomAwesome, thanks!
I'm not sure this works 100% for what you need, but I thought I'd give it a shot. I've used a built in array (sys.odcinumberlist) that you should have access to on your installation (assuming you have a relatively recent version of Oracle).
I left out the part where you would loop through the array you are currently passing in to your procedure to build up this new array that you can use in a SQL statement.

SLOW report performance with bind variable

Environment: 11.1.0.7.2, Apex 4.01.
I've got a simplified report page where the report runs slowly compared to running the same query in sqldeveloper. The report region is based on a pl/sql function returning a query. If I use a bind variable in the query inside apex it takes 13 seconds to run, and if I hard code a string it takes only a few hundredths of a second. The query returns one row from a table which has 1.6 million rows. Statistics are up-to-date and the columns in the joins and where clause are indexed.
I've run traces using p_trace=YES from Apex for both the bind variable and hard coded strings. They are below.
The sqldeveloper explain plan is identical to the bind variable plan from the trace, yet the query runs in 0.0x seconds in sqldeveloper.
What is it about bind variable syntax in Apex that is causing the bad execution plan? Apex Bug? 11g bug? Ideas?
tkprof output from Apex trace with bind variable is below...

Patrick, interesting insight. Thank you.
The optimizer must be peeking at my bind variables with it's eyes closed. I'm the only one testing and I've never passed %anything as a bind value. :)
Here's what I've learned since my last post:
I don't think that sqldeveloper is actually using the explain plan it says it is. When I run explain plan in sqldeveloper (with a bind variable) it shows me the exact same plan as Apex with a bind variable. However, when I run autotrace in sqldeveloper, it takes a path that matches the hard coded values, and returns results in half a second. That autotrace run is consistent with actually running the query outside of autotrace. So, I think either sqldeveloper isn't really using bind variables, OR it is using them in some other way that Apex does not, or maybe optimizer peeking works in sqldeveloper?
Using optimizer hints to tweak the plan helps. I've tried both /*+ FIRST_ROWS */ and /*+ index(ps pk_persons) */ and both drop the query to about a second. However, I'm loath to use hints because of the very dynamic nature of the query (and Tom Kyte doesn't like them either). The hints may end up hurting other variations on the query.
I also tested the query by wrapping it in a select count(1) from ([long query]) and testing the performance in sqldeveloper and in Apex. The performance in that case is identical with both bind variables and hard coded variables for both Apex and SqlDeveloper. That to me was very interesting and I went so far as to set up two bind variable report regions on the same page. One region wrapped the long query with select count(1) from (...) and the other didn't. The wrapped query ran in 0.01 seconds, the unwrapped took 15ish seconds with no other optimizations. Very strange.
To get performance up to acceptable levels I have changed my function returning query to:
1) Set the equality operator to "=" for values without wildcards and "like" for user input with wildcards. This makes a HUGE difference IF no wildcard is used.
2) Insert a /*+ FIRST_ROWS */ hint when users chose the column that requires the sub-query. This obviously changes the optimizer's plan and improves query speed from 15 seconds to 1.5 seconds even with wildcards.
I will NOT be hard coding any user supplied values in the query string. As you can probably tell by the query, this is an application where sql injection would be very bad.
Jeff, regarding your question about "like '%' || :P71_SEARCH_SOURCE1 || '%'". I've found that putting wildcards around values, particularly at the beginning will negate any indexing on the column in question and slows performance even more.
I'm still left wondering if there isn't something in Apex that is breaking the optimizer "peeking" that Patrick describes. Perhaps something in the way it switches contexts from apex_public_user to the workspace schema?

ADF Groovy Expression with bind variable and ResourceBundle

Now I have ViewObject which have WHERE clause with bind variable.
This bind variable is for language. Within bind variable I can change Value Type to Expression and into Value: I put +(ResourceBundle.getBundle("model.ModelBundle")).getString("language")+.
Now if I run Oracle Business Component Browser (on AppModule) this works. In my ModelBundle.properties there is language=1 name-value pair. And with different locale I have different language number.
Now if I put that ViewObject on one JSF, this bind variable expression does not work any more. Error:
*oracle.jbo.JboException: JBO-29000: Unexpected exception caught: java.util.MissingResourceException, msg=Can't find bundle for base name model.ModelBundle, locale my_locale*
Any ideas?

The most wierd thing is that, if I make ViewObjectImpl and insert this method
public String getLanguage() {
return (ResourceBundle.getBundle("model.ModelBundle")).getString("language");
and call it in Bind Variable Expression Value: viewObject.getLanguage()
IT WORKS!
But why with groovy expression it does not work?

SQL query with Bind variable with slower execution plan

I have the same query but instead running using bind variable (I test it with both oracle form and SQL*plus), it takes considerably longer with a different execution plan:-

TABLEA has around 3million record while TABLEB has 300 records. Is there anyway I can improve the speed of the sql query with bind variable? I have DBA Access to the database
Regards
Ivan

Many thanks for your reply.
I have run the statistic already for the both tableA and tableB as well all the indexes associated with both table (using dbms_stats, I am on 9i db ) but not the indexed columns.
for table I use:-
begin
dbms_stats.gather_table_stats(ownname=> 'IVAN', tabname=> 'TABLEA', partname=> NULL);
end;
for index I use:-
begin
dbms_stats.gather_index_stats(ownname=> 'IVAN', indname=> 'TABLEB_IDX_003', partname=> NULL);
end;
Is it possible to show me a sample of how to collect statisc for INDEX columns stats?

Bind Variables in SPARQL Queries

Hi,
I am interested in bind variables and their use between queries, however while I see the concept behind the example given in the documentation (http://docs.oracle.com/cd/E11882_01/appdev.112/e25609/sem_jena.htm#autoId15) I am not able to grasp how to exactly pass the results of a query_1 for an ?x variable to another query query_2.
Would it be possible to offer a more detailed explanation and a working simple code about how to do this using Jena Adapater.
Thank you.

Hi,
I am using the Java API to run SPARQL update queries, this is an example of what I am trying to achieve :
public static void runTestUpdateBinding() throws SQLException {
    String[] modelNames = new String[] { };
    String[] rulebases = new String[] { };
    OracleDataSource ods = new OracleDataSource();
    ods.setURL("ORACLE CONNECTION STRING");
    OracleConnection oc = (OracleConnection)ods.getConnection();
    Oracle oracle = new Oracle(oc);
    Attachment attachment =
        Attachment.createInstance(modelNames, rulebases, InferenceMaintenanceMode.NO_UPDATE, QueryOptions.ALLOW_QUERY_INVALID_AND_DUP);
    GraphOracleSem graph = new GraphOracleSem(oracle, "in_oracle", attachment, true);
    ModelOracleSem model = new ModelOracleSem(graph);
    //Insert few triples
    String updateQuery = "INSERT DATA {                                        " +
                         " <http://sub/a> <http://pred/a> <http://obj/a> .\n" +
                         " <http://sub/b> <http://pred/b> <http://obj/b> .\n" +
                         " <http://sub/c> <http://pred/c> <http://obj/c>    " +
    UpdateAction.parseExecute(updateQuery, model);
    //Run the update query
    updateQuery = "PREFIX    ORACLE_SEM_UEAP_NS:    <http://oracle.com/semtech#s$RDFVID%20IN(ORACLE_ORARDF_RES2VID(?),ORACLE_ORARDF_RES2VID(?))> \n" +
                  "PREFIX    ORACLE_SEM_UEPJ_NS:    <http://oracle.com/semtech#s$RDFVID> \n" +
                  "PREFIX    ORACLE_SEM_UEBV_NS:    <http://oracle.com/semtech#http%3A%2F%2Fsub%2Fa,http%3A%2F%2Fsub%2Fc> \n" +
                  "INSERT { <http://sub/UPDATED_SUBJECT>    ?p    ?o } \n" +
                  "WHERE { ?s    ?p    ?o }";
    UpdateAction.parseExecute(updateQuery, model);
    model.close();
Basically, I am expecting only "<http://sub/a> <http://pred/a> <http://obj/a>" and "<http://sub/c> <http://pred/c> <http://obj/c>" to match, however, "<http://sub/b> <http://pred/b> <http://obj/b>" also matches as you can see from the following results
| s                            | p               | o              |
===================================================================
| <http://sub/c>               | <http://pred/c> | <http://obj/c> |
| <http://sub/UPDATED_SUBJECT> | <http://pred/c> | <http://obj/c> |
| <http://sub/b>               | <http://pred/b> | <http://obj/b> |
| <http://sub/UPDATED_SUBJECT> | <http://pred/b> | <http://obj/b> |
| <http://sub/a>               | <http://pred/a> | <http://obj/a> |
| <http://sub/UPDATED_SUBJECT> | <http://pred/a> | <http://obj/a> |
Also, in the underlying generated SQL, there is no restriction on s$RDFVID as in SELECT queries (i.e: ...where (s$RDFVID IN(ORACLE_ORARDF_RES2VID(?),ORACLE_ORARDF_RES2VID(?))) )

$a_report to refresh a report but it is not picking up the bind variable

Hi
APEX          -     Application Express 4.1.0
Browsers     -     All
Database     -     11g2
I have a tree region on a page. When a user clicks a leaf of the tree I want to be able to use the ID to refresh a report in a different region on the same page
Code for when the user clicks the leaf
$('div.tree li a').click( function() {
node_id = $(this).parents('li:first').attr('id');
if (node_id.substr(0,node_id.indexOf('|')) == 'Y')
$s('P4_SELECTED_VALUE',node_id.substr(node_id.indexOf('|')+1));
alert('Value Set: ' + $v('P4_SELECTED_VALUE'));
//$a_report('28576803999973770','1','20','20');
$a_report($v('P4_REPORT_ID'),'1','20','20');
SQL Statement
SELECT *
FROM PRODS p WHERE PROD_CODE = :P4_SELECTED_VALUE
The problem I have is that when the report is run (I know it is refreshing) the P4_SELECTED_VALUE bind variable is set to NULL.
The alert pop contains the correct value and when I make the P4_SELECTED_VALUE visible it also contains the value?
Any help is much appreciated
Rob

Rob,
You need to insert P4_SELECTED_VALUE value into APEX session before refreshing the report.
Add following JS function in your page
//insert value into session using JS
function fnSetSessionState(pItem, pValue) {
    var vAjaxDummy = new htmldb_Get(null, $v('pFlowId'), null, 0);
    vAjaxDummy.add(pItem, pValue);
    var vDummy = vAjaxDummy.get();
    vAjaxDummy = null;
}and your code..
$('div.tree li a').click( function() {
node_id = $(this).parents('li:first').attr('id');
if (node_id.substr(0,node_id.indexOf('|')) == 'Y')
$s('P4_SELECTED_VALUE',node_id.substr(node_id.indexOf('|')+1));
alert('Value Set: ' + $v('P4_SELECTED_VALUE'));
fnSetSessionState('P4_SELECTED_VALUE',$v('P4_SELECTED_VALUE'));
//$a_report('28576803999973770','1','20','20');
$a_report($v('P4_REPORT_ID'),'1','20','20');
});This is how I used to do in version 3.2 or before. But now I prefer to use Declarative dynamic actions..

Hari

Bind Variable in SELECT statement and get the value in PL/SQL block

Hi All,
I would like pass bind variable in SELECT statement and get the value of the column in Dynamic SQL
Please seee below
I want to get the below value
Expected result:

Using the below block I am getting column names only not the value of the column. I need to pass that value(TEST,NYC..) into l_col_val variable
Please suggest

Thanks Billy, Would you be able to suggest any other faster method to load the data into table. Thanks,
As Mark responded - it all depends on the actual data to load, structure and source/origin. On my busiest database, I am loading on average 30,000 rows every second from data in external files.
However, the data structures are just that - structured. Logical.
Having a data structure with 100's of fields (columns in a SQL table), raise all kinds of questions about how sane that structure is, and what impact it will have on a physical data model implementation.
There is a gross misunderstanding by many when it comes to performance and scalability. The prime factor that determines performance is not how well you code, what tools/language you use, the h/w your c ode runs on, or anything like that. The prime factor that determines perform is the design of the data model - as it determines the complexity/ease to use the data model, and the amount of I/O (the slowest of all db operations) needed to effectively use the data model.

Using Bind Variable in a SELECT

Hi,
I'm trying to build up my SQL query at run-time using bind variables and in the Oracle® Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework 11g Release 1 (11.1.1) it says that 'After defining the bind variables, the next step is to reference them in the SQL statement. While SQL syntax allows bind variables to appear both in the SELECT list and in the WHERE clause, you'll typically use them in the latter context, as part of your WHERE clause.'.
However, when I try to use the bind variables in my SELECT list because I've had to set a type for the variable to String the variable gets inserted with inverted commas either side e.g. SELECT 'Service' FROM TestTable. Is it possible to use bind variables to insert a value into my select list without these inverted commas around it?
Thanks in advance,
Tom

OK, thanks for your response. Do you know of a way then where I can control my SELECT parameters programmatically? I'm currently trying to do it using the information in the chapter '35.9 Using Programmatic View Objects for Alternative Data Sources' from the Oracle® Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework 11g Release 1 (11.1.1). I think I'm part way there, would this be the correct way of acheiving what I want?
Cheers, Tom

A problem with bind variables in a shuttle

Hi
After days of research I cannot come up with a solution to this problem which I hope will be easy to describe.
I'm working on an apex.oracle.com workspace (4.02).
I have a page with
a) a region with tree which works well populated by a list of roles and users
b) a region with a shuttle with the following sql
List of values
select SOB_DISPNAME, SOB_ID
from VIEW_SYSTEMOBJECT
order by SOB_DISPNAME
Source
SELECT SOB_ID FROM VIEW_OBJECTSECURITY_GRANTED WHERE U_ID = :P19_SELECTED_ID
:P19_SELECTED_ID is a hidden textbox with the currently selected users id.
The above works very well - I select a user from the tree and the shuttle lhs populates with unselected object names and the rhs with objects selected for the user. A submit button drives a page process which clears out and then inserts the selection into a the table (objectsecurity)
So far so good.
I added a list box to the shuttle region (:P19_SOB_TYPE_LIST) so that the data being worked on could be filtered by type, its driven by a LOV that produces a value or 'PAGE', 'REPORT' ... etc.
I updated the above SQL to be
List of Values
select SOB_DISPNAME, SOB_ID
from VIEW_SYSTEMOBJECT WHERE SOB_TYPE = :P19_SOB_TYPE_LIST
order by SOB_DISPNAME
and the source
SELECT SOB_ID FROM VIEW_OBJECTSECURITY_GRANTED WHERE U_ID = :P19_SELECTED_ID AND SOB_TYPE = :P19_SOB_TYPE_LIST
So now I would expect that if 'PAGE' is selected in the list box then only objects that are pages will be seen.
However nothing at all appears.
If I substitute the bind variable :P19_SOB_TYPE_LIST for 'PAGE' ... WHERE SOB_TYPE = 'PAGE' it works perfectly. So why does :P19_SELECTED_ID do it's job but not P19_SOB_TYPE_LIST ?
I am probably making some ridiculously simple mistake but I just cannot spot it; is my syntax wrong?.
The session state is persisting so that I can see the value of :P19_SOB_TYPE_LIST being set to PAGE
Any help with this would be very much appreciated.

Hi Dirk
Thanks for that which looked promising!
I added P19_SOB_TYPE_LIST as the Cascading LOV Parent Item and removed it from the where clauses of both SQL's and the result was that all types are shown; corresponding to my original position.
I then added the where clause back to the LOV SQL and both shuttle boxes are blank again
I added back to the source SQL and again both boxes empty
Finally I removed the where clause from the LOV SQL (the only other combination) and again lhs box populated with all rows (not filtered) and rhs box blank.
So unfortunately that doesn't seem to have fixed it.
Many thanks for the help and any more will be greatly appreciated.
Regards
Charles

Asking for bind variable where none is needed

Good Morning,
I am still working these regexp date_time project.
I have a problem where oracle is asking for a bind variable where it doesn't need any as far as I can see. I am trying to capture various date times in a column and formatting them into one default format used by oracle. Here is what I got which works before I wrap it in the TO_DATE function
There are many when then's but I am using only one here.
select case
when regexp_substr(date_time,'^(0?[1-9]|1[0-2])/(0?[1-9]|[1-2][0-9]|3[0-1])/9[[:digit:]]{4}') is not null
then regexp_substr(date_time,'^(0?[1-9]|1[0-2])/(0?[1-9]|[1-2][0-9]|3[0-1])/9[[:digit:]]{4}')
else date_time
end as new_time
from raw_data;
The above statement works
Now when I want to format the date that I found with this:
select case
when regexp_substr(date_time,'^(0?[1-9]|1[0-2])/(0?[1-9]|[1-2][0-9]|3[0-1])/9[[:digit:]]{4}') is not null
then TO_DATE('regexp_substr(date_time,'^(0?[1-9]|1[0-2])/(0?[1-9]|[1-2][0-9]|3[0-1])/9[[:digit:]]{4}')','MM/DD/YYYY')
else date_time
end as new_time
from raw_data;
I get a request to insert a value for the digit as a bind variable. The digit should be populated from the when statement when it returns not null when a date is found.
Could some one please tell me even if what I wrote here is even possible or make a suggestion to the syntax to get around this issue?
All this is going to be incorporated into an update statement later on.
I am running this on sql developer, oracle 11g.
Thanks for your help in this matter in advance.
regards,
Al

From looking at the code, as you have not supplied any scripts to create a table and demonstrate the error...
Your case statement is trying to return two types
select case
when regexp_substr(date_time,'^(0?[1-9]|1[0-2])/(0?[1-9]|[1-2][0-9]|3[0-1])/9[[:digit:]]{4}') is not null
then TO_DATE('regexp_substr(date_time,'^(0?[1-9]|1[0-2])/(0?[1-9]|[1-2][0-9]|3[0-1])/9[[:digit:]]{4}')','MM/DD/YYYY')
else date_time
end as new_time
from raw_data;or simply
select case when <expr>
            then <RETURN A DATE>
            else <RETURN A VARCHAR2>
        end as new_time
from raw_data;The column cannot be both.
Sorry I don't know your requirements.
You could drop the else part and just return the converted date.
You could fetch it back in two columns, the ones you can convert in one column (Which would be an oracle date type),
the ones you cannot convert in another (which would be varchar2).

Combine select and update into single statement,without bind-variable

I have a problem, that I think is not possible to solve the way I want to, but I just wanted to check before leaving the idea...
I am looking for a way to combine the select and the update statement into one single statement. This is what I wan't to achive: select some data, and update the data selected before returning them.
On this site http://www.psoug.org/reference/update.html I see that the following are possible:
var bnd1 NUMBER
var bnd2 VARCHAR2(30)
var bnd3 NUMBER
UPDATE employees
SET job_id ='SA_MAN', salary = salary + 1000,
department_id = 140
WHERE last_name = 'Jones'
RETURNING salary*0.25, last_name, department_id
INTO :bnd1, :bnd2, :bnd3;
I need to have this as a single statement, and cannot use bind-variables. So I was hoping that something like this could be possible:
UPDATE customer c
SET c.HAS_CREDIT ='1'
WHERE c.HAS_CREDIT = '0'
RETURNING c.CUSTOMER_NO, c.FIRSTNAME, c.LASTNAME
where c.HAS_CREDIT = '1'
But this doesn't compile, complaining of missing into (ORA-00925: missing INTO keyword). And even though I would like this to be possible because this would solve my current problem, I think it would be very confusing. For instance; would the where clause of the returning part be operating after the update or before?
Any comments or suggestions on how to get it work in a single statement, or should I just leave this path straight away?

Hi,
RETURNING only works with bind variables, see
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14261/returninginto_clause.htm#sthref3006
The real problem is that the form of RETURNING clause with bind variables is only valid for single row update or insert statements.
To update (or insert) multiple rows and return the data, you will need to use
RETURNING BULK COLLECT INTO clause. See
http://download-uk.oracle.com/docs/cd/B19306_01/appdev.102/b14261/tuning.htm#sthref2236

Colin
