SQL query to populate JTable
I'm trying to create a simple SQL query to populate a JTable. I don't seem to be able to get the syntax correct in order pull the info from an Access database when using a WHERE clause.
Here is what query looks like.
"SELECT * FROM Table1 [WHERE Tape = " + localTape + "]";.
Any help would be greatly appreciated.
try using single quotes beforeand after this "+localTape+" as '"+localTape+"' Instead of worry about whether you have used the quotes correctly or not, use a PreparedStatement:
String sql = "INSERT INTO Page (Name, Title) VALUES (?, ?)";
PreparedStatement stmt = connection.prepareStatement(sql);
stmt.setString( 1, "Name1" );
stmt.setString( 2, "Title1" );
stmt.executeUpdate();
the PreparedStatement will worry about the proper formatting of the request.

SQL query to populate the records, the maximum processed should be less than 10 records per week.
Dear All,
I have a requirement, to write a SQL query to populate the records which are inserted less than 10 no of records.
The tables has the cretaed_date column and along with other key column which will have unique values.
Ex1: The user might have inserted records from application, per week basis, between the date range '01-jun-2013' - 08-jun-2013 , the no of records created by the user during this week may be less than 10 records or more.
But I want to populate the records by giving date range that too, it should pick the records the count which fall with in 10 records.
I dont want the query to populate the records if the user has inserted more than 10 records in a week.
Ex2:
User 1 has created 15 records during the week 1 ( the query should not populate this ).
User 2: has cretaed less than 10 records from the UI during the week 2. ( This details should get populated ).
ThanksUse COUNT to find how many rows where inserted in a week.
If this does not answer your question then please read Re: 2. How do I ask a question on the forums? And provide necessary details. -
How-To populate SELECT LIST default value from SQL Query
OK, I've done my homework, and did not find my answer in the Forum, so here it is.
I have a Page that displays fields from a SQL Query. The Page also has below that radiogroups, checkboxes, and Select Lists to allow the user to change values in the fields that are displayed at the top of the Region. I am able to pre-populate the radiogroups and checkboxes by performing a SELECT in the 'Source value or expression' of the Source area of the Page Item.
However, I am unable to do the same for the Select List fields. Their default value ends up being the first value in the LOV ('-- None --' for NULL values). Source Used: Only when current value in session state is null. Source Type: SQL Query. Also, when I first go into the Page when running it, and check the Session State values, they are all null, so I don't understand why the field is not populated by the SQL Query statement as the radiogroups and checkboxes are.
Any suggestions??? I've tried all sorts of combinations.Thank you for the suggestion.
I had considered that, but cannot do so, because we are using Oracle Application Express more for development than for data containment.
We have all our data in an Oracle 10.g DB which is separate from the OAEX server, and the OAEX app will reference that data via VIEWs and DB LINKs. We are doing so primarily as an added data security layer, where the data is housed separate from the app, in case the Web site is ever compromised. The data that can be viewed is restricted to a subset of the actual data that is available.
Since the data is on a separate server, (I assume) we will not be able to set the source type to Database column, because (I asume) that is dependent upon the data being housed by the OAEX server.
That still leaves me with having to populate the field with a SELECT statement from the Oracle DB. This unfortuneately is almost a show-stopper for me because of down-stream processing data requirements. Have not been able to come up with contingencies yet. -
Populate a select list based on sql query
I need to populate a select list using an sql query based on the value value I get from the previous page sent using link . How can I achieve this behaviour ? I tried giving select app_item_id a,app_item_id b from app_item_definition where app_id = :P11_APP_TDL_ID order by 1 in LOV, but it doesn't work . Please advice .
Okay, I just had the right idea and it's working well! Sorry for posting!
I return the name of the employee that has edited a dataset and simply add all others of the logged on department! Really easy! Should have thought of that before posting! ;-(
The correct code is select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter a, vt_tbl_punktdaten b where a.cnt_bearbeiter = b.int_bearbeiter and
inv_pt_id_sub = :P4_PTIDS
union select str_bearbeiter, cnt_bearbeiter from vt_tbl_bearbeiter where int_behoerde in (SELECT
CNT_REGIERUNGSBEZIRK FROM TBL_REGIERUNGSBEZIRK where STR_REGIERUNGSBEZIRK = lower (:app_user))Bye,

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error
I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;
end;
The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?
Shane.What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query. -
Store SQL Query in Oracle database
Hello,
I am storing SQL query in database. here is an example of query.
INSERT INTO TABLE_1 Values (' " + getValue1() + " ', ' " + getValue2() + " ' )
getValue1() and getValue2() are functions to retrieve values.
When I read query from the database and execute it, it doesn't read values from function.
After I read query from database I would expect it to be
INSERT INTO TABLE_1 Values ('value1', ' value2' ) but it is not reading values and trying to execute whatever I got from database.
Any help?
ThanksThanks for your reply. Let me give you more info.
All I am trying to do is storing queries in oracle
database to use it in future for reporting. As I am
doing reporting where clause will be different every
time. Reporting involves queries not updates. But in any case that means that you would use a java SQL string that is useable via a prepared statement. As such your statement would look like....
INSERT INTO TABLE_1 Values (?,?)
Is it not possible to substitute variable string I
got from database?What do you mean?
SQL is SQL. You construct SQL so it is valid and runs. Can you construct SQL so it runs a function/select and uses that value in some more SQL - depends on the database, but usually.
But that has nothing to do with java - it is SQL.
Query contains variables that I have in Java code .Then it is SQL. It is java. You use bind variables (see PreparedStatement) and assign values to it.
The SQL for such a query would look like the following...
select field1, field2 from table1 where id=?
In your java you would then use something like PreparedStatement.setInt(1, 100), to fill in the value for the '?' in the above.
You might also note that your solution will not work for any arbritrary SQL statement unless you are also storing meta data about the SQL itself. For instance the following SQL statements would return the same result set but your java code would have to populate the bind variables different for both...

Edited by: Bilal on 27-Dec-2012 10:07Bilal, thanks for the nice problem! Another possibility for duplicate checking is to write a small PL/SQL function returning 1 if a duplicate id is found, then equate it to 0: 'Duplicate_Token_Found (p_str_main VARCHAR2, p_str_trial VARCHAR2) RETURN NUMBER'. This would parse the second string and might use p_str_main LIKE '%,' || l_id || ',%' for each id. Anyway the full query (without that) is given below:

Which row was clicked in an SQL Query (updateable report)?
I have an application with a report based on an SQL Query (PL/SQL function ...) defined on the Global Page.
On the pages where the report is used, I want to click in a particular column (TCKT_ID) and pass the values in that row to another page for processing.
Things I would like to know:
1) How to determine which row was clicked? The column is TCKT_ID and it is used as a link to another page. The SQLis a non-trivial (for me!) join of tables.
2) How to refer to the values of the other columns in that row? Because I format with "div," the columns are named -- no "f02", "f03", etc.
3) How to pass multiple values (ENAME, JOB, MGR, SAL, COMM) to the target page? You might ask: Why not just re-query for the data using a unique key. Splendid idea, but the unique key is four columns so I still need some way to pass these four values to have that unique key.
I've constructed a "pretty close" example of the situation here:
WS APEX_EXAMPLES_01
demo / demo
Application: Row Info 10782 - Page 0 has the report. Page 1 displays it with a link (in red) to page 2.
I think I can complete most of what I need if someone can just show me how to get, say, the ENAME of the row clicked on page 1, so I can use it to filter the query on page 2 to just this row clicked on page 1.
Using <tt> </tt>, I tried to display the actual row from View -- Source of the real report I'm dealing with but it just comes out like this

ARS003_TESTNBDI wonder if I'm not understanding something. This seems like a very simple thing to do without any "tricks"
Take a look, I've modified the LINKING_NUMBER column on the p0 report.
Basically, you just specify the fields you want to populate and their assignments. I added 4 destination fields on p2 to receive the assignments. Then you can do anything you want with them like modifying a report, etc...
The only trick here is that in order to pass more than 3 items in the URL you need to change your link type from Page in this application to URL. Then you can specify lost of items this way.
Thanks

SQL query slow with call to function
I have a SQL query that will return in less than a second or two with a function in-line selected in the "from" clause of the statement. As soon as I select that returned value in the SQL statement, the statement takes from anywhere from 2 to 5 minutes to return. Here is a simplified sample from the statement:
This statement returns in a second or 2.
select A.pk_id
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
if I add this function call in, the statement runs extremely poor.
select A.pk_id,
II.ytd_unx
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
Here is the function that is called:
create or replace FUNCTION calc_ytd_class_abs2 (p_fk_stu_schedule in varchar2,
p_legality in varchar2) return number IS
l_days_absent number := 0;
CURSOR get_class_abs IS
select (select nvl(max(D.days_absent),'0')
from cut_code D
where D.pk_id = C.fk_cut_code
and (D.legality = p_legality
or p_legality = '%')) days_absent
from stu_schedule_detail B, stu_class_attendance C
where B.fk_stu_schedule = p_fk_stu_schedule
and C.fk_stu_schedule_detail = B.pk_id;
BEGIN
FOR x in get_class_abs LOOP
l_days_absent := l_days_absent + x.days_absent;
END LOOP;
return (l_days_absent);
END calc_ytd_class_abs2;Query returns anywhere from 6000 to 32000 rows. For each of those rows a parameter is passed in to 4 different functions to get ytd totals. When I call the functions in the in-line view but do not select from them in the main SQL, the report (oh, this is Application Express 4.0 interactive reports, just an FYI) runs fast. The report comes back in a few seconds. But when I select from the in-line view to display those ytd totals, the report runs extremely slow. I know there are the articles about context switching and how mixing SQL with PL/SQL performs poorly. So I tried a pipeline table function where the function for the ytd totals populate the columns of the pipeline table and I select from the pipeline table in the SQL query in the interactive report. That seemed to perform a little worse from what I can tell.
Thanks for any help you can offer. -
SQL Query (PL/SQL function body returning SQL query) Error
I'm an ApEx newbie, not a PL/SQL developer (more of a Web application developer) and I'm getting an error that prevents me from saving some PL/SQL code. I've looked over it all afternoon, but can't tell what's wrong. I may even be trying to do something inappropriately, or really stupid.
The code is below. The error I get is - "Function returning SQL query: Query cannot be parsed within the Builder". Any help is appreciated, and thanks in advance. If you need more details of what I'm trying to do let me know.

Good question.
Before I answer that question I'll give some detail on the application. That may help too. The application is a supplier search which searches the Oracle vendor tables (po.vendors, po_vendor_sites_all, po_vendor_contacts). The vendor/vendor site relationship is one to many. The site is based on the Org_ID. The supplier search is built to work solo, or to be called by another application. If it is called by another application one of the values passed is the Org_ID, so that only the sites that pertain to the user's org_id are shown. If the appl is called solo the Org_ID is not known, so the SQL should return all sites.
I figured the easiest way to check if the program was running solo or was called was to check the G_ORG_ID value in my PL/SQL that builds the site report. You helped me with that code. (I am hiding buttons by checking if the G_ORG_ID field is null and they display/hide properly.)
So, how is G_ORG_ID populated? It is on Page Zero, and is populated via the URL when the appl is called. (That aspect works great.) If it is called by another application G_ORG_ID is populated and my PL/SQL works. But, if the appl is called solo the field is not populated. When the PL/SQL runs I cannot get it to run the code for when G_ORG_ID is not populated.
I am at the point that I don't know if I need to populate G_ORG_ID in some way when the appl is running solo (kinda tricky, because I need to use that field to determine if it is running solo), or if I need to check it differently in the PL/SQL IF.
I have experimented with both the default value, and have checked for different values in the PL/SQL IF, but nothing works.
Thanks for your help, and let me know if you have any other questions on this matter.
Thanks, Tony -

How to execute SQL Query in Code behind Using infopath 2010?
Hi,
I've repeatable on infopath form, and want bind it throuth code behind from SQL table. My question is that how to execute SQL Query in code behind from infopath as well as how would get Query result to bind repeatable control?
Thanks In Advance
Shoeb AhmadHello,
You first need to add new SQL DB connection then you need execute connection from code behind.
See below link to create new connection
http://office.microsoft.com/en-in/infopath-help/add-a-data-connection-to-a-microsoft-sql-server-database-HP010092823.aspx:
http://www.bizsupportonline.net/infopath2010/connect-infopath-2010-sql-server-2008-table.htm
Then use below code to execute this connection:
AdoQueryConnection conn = (AdoQueryConnection)(this.DataConnections["Data connection name"]);
string origCommand = Select * from tablename;
conn.Command = origCommand;
conn.Execute();
Finally bind your table:

Executing SQL query in portal database
Hi ,
I wish to do a simple POC . I need to create a table from NWDS , populate it with some data and then access the table data using an sql query . I am aware how to create a table but I am not sure where exactly to write the query .
What I would like to understand is
1) If I create a table where would that table get created (The database) ?
2) Where would I write that query in NWDS ?
3) How would I execute that query in that database ?
Please help for the same .

Having troubles passing values of Shuttle control to SQL Query of Report and Chart Region
Hello,
I am very new to APEX and need help for one of the Pa.I have a shuttle control on my page which populates Categories. Once user selects Categories from this control, I wish to pass the values to following SQL query :
select * from emp_class where category IN ( LIST of VALUES FROM RIGHT SIDE SHUTTLE).
I tried various ways of doing this including writing a java scripts which reads shuttle value, converts it into below string
'Category1',Category2',Category3'. Then I set this value to a text box. And then I was expecting that below trcik would work
select * from emp_class where category IN (:TXT_VALUES)
I am sure this is not right way and hence its not working. Can you please guide me here with options?
Many Thanks,

Don't understand what this means. What is "Pa"?
select * from emp_class where category IN (:TXT_VALUES)
I am sure this is not right way and hence its not working. Can you please guide me here with options?
This is a common fallacy. In
select * from table where columnvalue in (7788, 7839, 7876)
(7788, 7839, 7876) is an expression list and the predicate is evaluated as a membership condition.
In
select * from table where columnvalue in :P1_X
:P1_X is a scalar string, incapable of containing multiple values.
In an APEX standard report, a PL/SQL function body returning an SQL query report source with lexical substitution can be used to produce a "varying IN-list":
return 'select * from table where columnvalue in (' || :P1_X || ')';
where P1_X contains fewer than 1000 values, has been sanitized for SQL injection, and string values are properly quoted.
Some people suggest the following approach, which will also work in APEX interactive reports:
select * from table where instr(':' || :P1_X || ':', ':' || columnvalue || ':') > 0
However this is non-performant as it eliminates the possibility of the optimizer using indexes or partition pruning in the execution plan.
See varying elements in IN list on Ask Tom, and emulating string-to-table functionality using sql for efficient solutions. -
Hi friends,
Can u plz tell me when exactly we can use "Query SQL Stmt" and "Update SQL Stmt"?If you have a scenario that uses the JDBC adapter to connect to the "sending" system and pull data out of it, you will use these options.
You formulate a SQL statement that queries the database and gets certain information, the JDBC adapter then uses that information to populate the message type that you built in the integration repository.
You then create an update statement with SQL to tell the database what to do after it has grabbed the data it needs and populated the message type for mapping.
Say for example you wanted to get all the data from the usr01 table in your SAP database (bad example, but bare with me) you could do something like this:
<b>SQL QUERY STATEMENT:</b> SELECT * FROM USR01
And then following that you wanted to change the MANDT table (once again, don't actually run this command)
<b>UPDATE SQL STATEMENT:</b> UPDATE USR01 SET MANDT='100' WHERE MANDT='100'
