Oracle Views with Column type as CLOB

I have a table which has a column of type CLOB. I am trying to creating a view which has all the columns of that table.
I get
Warning: View created with compilation errors.
SQL> show errors;
No errors
Can any one help me how to create a view on a table wihich has a CLOB/BLOB column types. Also how to select the clob data from the view
sree

Are you the owner of the view you created?
Check out the documentation for the SHOW command.
If you omit schema, SHOW ERRORS assumes the object is located in your current schema.

Problem with Column types and String

Hi
I have some problem while comparing against empty string.
My column is of type it_Linked_Button. Actually it seems that column type doesn't matter.
If cell that belongs to this column is empty and based on other columns' values I put some value into this cell.
It works fine.
But when I clear that cell and try to put some value again nothing happens.
In my if statement I'm checking against empty string and it fails second time.
Before I put anything in that cell (in debugger) that value is "" so it is empty and it works.
(OK, I see that after I posted this message it was slightly reformated)
But after I put something and clear that cell and try to put something again (in debugger) I get "(here is some long space) " which fails String.IsNullOrEmpty(var) test.
What is going on? Has it something to do with Column type?
How to clear it so I can put something in it again?
One more thing - to put values and clear it I use DbDataSource SetValue method. And String.Empty or ""(doesn't matter)
Thanks
Kamil
NOTE
I made some workaround that gives me the behaviour I want but still I would like to know what is going on?

1. Could you define an Enum? Then you could switch on enum values.
2. Wait for Java 7 which is supposed to extend switch to strings?3. Put the target strings in a collection, write a loop to find the match in the collection and use the matching index in the switch statement. At least that will get rid of the hashcode kludge, where it won't mistakenly 'match' a string which isn't the actual target.3b: Map<String, Command>Yep.
I also wanted to point this out to the OP:
For example, let's say the 7 character string "BugABoo" happens to have the same hashcode as "EDI_DOC". And let's say your input just happens to have the string "BugABoo" in it, where you're extracting the 7 character substring. See the problem? You're getting "BugABoo" but treating it as if it really were "EDI_DOC", by virtue of comparing hashcodes instead of actual strings.
OOPS!

View with columns based on function - problem with query

Hi,
I'm using Oracle 9i;
I've created a view which has columns based on a table columns (multiple columns from 1 table) and funtion (multiple columns based on 1 function).
The function takes ID as the first argument and name of the column to determine which value to return as the second one.
Here is a sample of such function (simplified):
FUNCTION my_function
(in_id IN NUMBER, in_col_name IN VARCHAR2)
RETURN VARCHAR2
IS
c_name VARCHAR2(100);
c_last_name VARCHAR2(100);
BEGIN
SELECT T.NAME, T.LAST_NAME
INTO c_name, c_last_name
FROM TABLE_1 T, TABLE_2 Z
WHERE T.PK = Z.FK
AND Z.ID = in_id;
IF in_col_name = 'NAME' THEN
RETURN c_name;
ELSIF in_col_name = 'LAST_NAME' THEN
RETURN c_last_name;
END IF;
END;
For simplicty I've restricted the number of columns.
CREATE OR REPLACE VIEW my_view
(ID, NAME, LAST_NAME)
AS
SELECT
T.ID ID
,CAST(my_function(T.ID,'NAME') AS VARCHAR2(100)) NAME
,CAST(my_function(T.ID,'LAST_NAME') AS VARCHAR2(100)) LAST_NAME
FROM TABLE T;
There is no problem with query:
SELECT * FROM my_view;
The problem arises when I query the view (regardles of '=' or 'LIKE'):
SELECT * FROM my_view
WHERE name LIKE '%some_part_of_name%'
The query returns rows for same names, for same it doesn't. If I put '=' and the whole name the query returns nothing, but when I put 'LIKE' and the first letter it returns rows in some cases.
I've tried to debug this situation and I've discovered that the function recives ID not in the proper order and not the same amount of times - in explicit:
for each ID in (1, 2, 3, 4, 5, 6, ... , 100) the function should be called twice for each ID and in the same order, but it does not.
I get 1, 1, 2, 3, 3, 6, 20, 20 and so on.
Help needed.
Greetings.

The problem is more complicated than the solutions provided here.
The reason why I'm using the function is this:
the original view was constructed using multiple union all selects and the speed was terrible. I've created the index on the base table to obtain a proper sort. For retriving all records at once the view works perfectly, but if one wants to query by columns based on function the results are suprisng - sometimes there are, some times there are none, or if you serch with "like" and only a part of string there are results, but with "=" there are no results.

Joint 2 datatable with column type double with a seperater

Can anyone please tell me how to merge 2 datatable of column type double with a seperator (|). one with datetime header and 2nd table with integer headers, like this
table 1
01/02/2015   01/03/2015
12346          47894
table 2
1               2
7899      45678
to become
01/02/2015        01/03/2015
12346 | 7899    47894 | 45678
thanks

Hi Sysaide,
According to your description, you'd like to migration the two dataTable to one.
What is the corresponding relationship of these two DataTables? Or when you migrating, the 01/02/2015 column and 1 column are fixed to one column. what is the relationship between these two columns?
Or, Does the first column of table1 correspond to the first column of table2? the second correspont to the second? ...
If the column index is corresponding each other. you could use the following way.
Getting out the value of each cell, then rebuild a new table to get this new value.
In your example, your column type is DataTime, but the value in the column is still string type. The below sample is used two different column type, string and int. And I show the result in a dataGridView.
DataTable dt1 = new DataTable();
dt1.Columns.Add("01/02/2015", typeof(string));
dt1.Columns.Add("01/03/2015", typeof(string));
DataRow dr = dt1.NewRow();
dr["01/02/2015"] = "11";
dr["01/03/2015"] = "12";
dt1.Rows.Add(dr);
dr = dt1.NewRow();
dr["01/02/2015"] = "21";
dr["01/03/2015"] = "22";
dt1.Rows.Add(dr);
DataTable dt2 = new DataTable();
dt2.Columns.Add("1", typeof(int));
dt2.Columns.Add("2", typeof(int));
DataRow dr2 = dt2.NewRow();
dr2["1"] = 1111;
dr2["2"] = 1122;
dt2.Rows.Add(dr2);
dr2 = dt2.NewRow();
dr2["1"] = 2211;
dr2["2"] = 2222;
dt2.Rows.Add(dr2);
DataTable dt = new DataTable();
dt = dt1.Clone();
for (int i = 0; i < dt1.Rows.Count; i++)
dt.Rows.Add();
for (int j = 0; j < dt1.Columns.Count; j++)
dt.Rows[i][j] = dt1.Rows[i][j].ToString() + " | " + dt2.Rows[i][j].ToString();
this.dataGridView1.DataSource = dt;
Result:
If you have any other concern regarding this issue, please feel free to let me know.

OSB Service with Oracle AQ with payload type SYS.AQ$_JMS_TEXT_MESSAGE

I am trying to write a web-service to Enqueue/Dequeue messages from an AQ with payload type SYS.AQ$_JMS_TEXT_MESSAGE defined in Oracle DB.
In my understanding is that I need to create a JMSModule within weblogic with a ForeignServer defined within it to enqueue/dequeue message to/from the AQ.
I have created Datasource, JMSServer, JMSModule, ForeignServer (created ConnectionFactory with localJNDIName="MyQueueCF" and RemoteJNDIName as "QueueConnectionFactory" and Destination with localJNDIName="MyQueueDest" and RemoteJNDIName="Queues/<queue_name_in_DB>")
My business service has an endpoint "http://localhost:7001/MyQueueCF/MyQueueDest"
When I am testing my service to populate message on to the Queue. I get the following error:
The error was oracle.jms.AQjmsException: Error creating the db_connection
My questions are:
* Am I following the correct procedure to talk to AQ with JMS text message type payload?
* If yes, how can I get around the issue I am stuck with?
Please help!
Thanks.

Example:
conn / as sysdba
begin
dbms_aqadm.create_queue_table
( queue_table=> 'SCOTT.AQJMS'
, queue_payload_type=> 'SYS.AQ$_JMS_TEXT_MESSAGE'
, compatible=> '9.1'
end;
This worked fine for me after a standard DB-installation.

Oracle Views with input

Oracle Version:Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64
Hi Experts,
Is it possible to write a view with input and with IN clause in where cluase ....For Example I want to create a view like Below ..
The below query may be syntactically wrong , but my intension of writing is similary to this. And the query should contain a IN caluse and A union as below...
create or replace VIEW view_name (col1,col2, P_inputparam VARCHAR2)
as
SELECT Col1,Col2
FROM table_name1
where any_column11 in (
&P_inputparam
UNION
SELECT Col1,Col2
FROM table_name2
where any_column22 in (
&P_inputparam
Thanks In advance.

Not like that... no.
What you're using as "input" there are SQL*Plus substitution variables. Those values are requested by SQL*Plus before the code is sent to the database and compiled. Code that runs on the database has no way of interacting with a client keyboard or screen, so you cannot get stored code to prompt for user input.
See: {message:id=10744582}
It's possible to use SYS_CONTEXT to get a view to pick up a value that has been previously assigned before the view is used, though I rarely find a need to do this myself.

Replicate an oracle view with SLT

Hi -
Using Oracle 11g and SLT 2011_1_731 Patch 7 with Hana rev 82
I am trying to replicate oracle views in hana through SLT
Scenario 1:
tables T2 and T3 with View T2_T3_view
If I follow this thread SLT view replication
It creates the view as a table in hana but does not populate it with any data.
Scenario 2 -
I have 2 oracle tables - T4 and T5. I have a view T4_T5_VIEW that joins the 2 tables.
I followed steps in a document I received to replicate the view syntax as well as the tables.
1) replicated both tables T4 and T5 - success
2) stopped replication on T4
table exists in hana with data but no replication
3) using LTRS, assigned the view T4_T5_VIEW to table T4
4) changed the performance option
5) restarted replication on T4
The view gets created as a table, but table T4 gets and error and does not replicate.
The view gets no data
What is the proper process for an oracle table?
I have a very complex view with 5 source tables I want to replicate.
Thanks
Diane

sorry,
with the query
SELECT TAB2.COD_M ,
COUNT(TAB1.COD_MAT) count_mat
FROM TAB2,
TAB1
WHERE TAB2.COD_R (+) = TAB1.COD_MAT
AND TAB1.COD_R IN ('1','3')
GROUP BY TAB2.COD_M
I get:
COD_M..........COUNT_MAT

00116220...........1
00116300...........2
00119320...........1
00119450...........1
...................0
but I'd like to get this output:

Materialized View with column based on PL/SQL function returning object

I have the following problem - it is known that materialized view wants PL/SQL functions used in it to be DETERMINISTIC. And it appears that a function which returns SDO_GEOMETRY cannot be DETERMINISTIC - I can add DETERMINISTIC modifier to my function which returns sdo_geometry based on USNG grid ID and save the package, and it compiles and runs fine with regular queries, but when it comes to materialized view (mview), the following error is thrown:
ORA-12018: following error encountered during code generation for "SCHEMA"."MVIEW_NAME"
ORA-00932: inconsistent datatypes: expected NUMBER got MDSYS.SDO_GEOMETRY
Looks like DETERMINISTIC modifier is not fully supported for object types. I have tried to use SDO_CS.FROM_USNG Oracle's function, and it appeared that this function is also non-deterministic - I cannot refresh mview with P or F on-demand refresh method (see http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14223/refresh.htm#i1008349 for a list of on-demand refresh methods). Without that function I can refresh mview with P or F flags.

Hi,
Yes, the Chart Series can be based on "Function Returing SQL Query" and the "SQL" would be something like:
DECLARE
vSQL VARCHAR2(1000);
BEGIN
vSQL := 'SELECT NULL LINK, ENAME LABEL, SAL VALUE FROM EMP ORDER BY ENAME';
RETURN vSQL;
END;You should tick the "Save query without validation" underneath that. Without this, there is a validation error - the ; at the end is required to get the chart to function correctly but the validator sees this as an error.
You would need to create this separately from the report. No matter how you did it, the chart would still run a SQL statement to generate the output. If you wanted to use the "same data", then you could create a collection using the PL/SQL and base both the report and the chart on the collection instead.

How to disable Oracle table NUMBER column type auto round-up

Below is an example,
SQL> create table a
a_col1 NUMBER(8, 2)
SQL> update a set a_col1=1.999 where ...
I found column 'a_col1' of table 'a' value will be 2.00, but the application is for some financial calculation and doesn't allow any difference of the amount value (like, 1.999 <> 2.00), what I want to achieve is to disable the Oracle NUMBER type auto round-up and make above 'update' SQL fail with error, so I can trap the error and handle it in the program.
Could anyone advise me how to achieve above or any good suggestion ? Thanks.

I found column 'a_col1' of table 'a' value will be 2.00, but the application is for some financial calculation and doesn't allow any difference of the amount value (like, 1.999 <> 2.00), what I want to achieve is to disable the Oracle NUMBER type auto round-up and make above 'update' SQL fail with error, so I can trap the error and handle it in the program.
Could anyone advise me how to achieve above or any good suggestion ? Thanks.Oracle does not auto-round.
you have data presentation problem; not data storage problem.

How to create a view with columns from multiple rows

I have posted this in SQL/PSL forum, but I hope database experts in this group can give me ideas too, also the need is from BI reports.
I have a table, say, project_milestones, which has these columns in concern:
proj_id, milestone_name, actual_end_date
with data:
proj_id, milestone_name, actual_end_date
===== ================ ==============
1001, Key Element Approve, 2009-10-02
1001, Final Synopsis, 2009-10-07
1001, Final Protocol Approved, 2009-10-15
1001, FPFV, 2010-01-10
1001, LPFV, 2010-03-12
1002, Key Element Approve, 2008-12-02
1002, Final Synopsis, 2009-01-07
1002, Final Protocol Approved, 2009-01-12
1002, FPFV, 2009-03-30
1002, LPFV, 2009-10-04
There are about 10 milestones in each project.
I have to create a view to flat these data at project level, looks like this:
proj_id, key_element_date, final_synopsis_date, final_protocol_approved_date, FPFV_date, LPFV_date, key_element_to_final_synopsis_days, final_synopsis_final_protocol_days, ....
How can I do this?
Thanks,

Thanks,Create a pivot table and put "milestone_name" in the Columns section under the Labels.
Put "actual_end_date" in the Measures section and change the Aggregation Rule to "Max."
The rest of the attributes keep in Rows section.

Problems on selecting views with french characters into column names

Hi All,
I have views with column names such as "Détermination Planimétriq" or "Année de construction:*";
I can get in my c# function this columns names from ALL_VIEWS dictionary table, but if I try to make a selectionby use of an OracleCommand, Oracle returns an "Invalid identifier" error:
SELECT "Détermination Planimétriq" FROM mytable;
System.Data.OracleClient.OracleException (0x80131938): ORA-00904: "Determination Planimetriq": invalid identifier at System.Data.OracleClient.OracleConnection.CheckError(OciErrorHandle errorHandle, Int32 rc) at ...
Any suggestion?...

Be wary of using character codes outside the Western European "simple" alphanumeric [A-Z0-9] for object names, i.e. columns, table names, function and procedure names, and so on.
First reason, there is a 30 character limit for most object names, and characters that have to be spelled out with unicode characters take more space, i.e.:
select dump( 'Détermination Planimétriq' ) from dual;
DUMP('D?TERMINATIONPLANIM?TRIQ')
Typ=96 Len=29: 68,239,[ ... ]Although the varchar string for that column name looks like 25 characters, it needs room for 29 to store the e<acute> character. And could also depend on the client settings. Using case sensitive names is not a best practice, its better to avoid specifying objects with the double quotes.

Proper showing value of a column type chart in BI 7.0

Hi,
I am in BI 7.0. I created a Web template with column type chart. I want to show the column value only when users move the cursor on top of the column.
The problem is when system showing value also show the category/serious and category description. Is there any way to show value only?
Thanks for your help,
Frank

Hi Wond,
Thanks for your quick response.
Your solution is for BW 3.5 or BI 7.0? I remember with BW 3.5, WAD has chart property and option. But, I dont think BI 7.0 has chart option. I am with BI 7.0. I clicked on property and nothing happens. I dont know is my system setup issue or other. When I modify chart property, I have to use Edit -> Wizard or Refine.
Any other solution?
Regards,
Frank
