I have a query which is using literals
strquery:='SELECT SUMTOTAL FROM tab1 WHERE BATCHNO = '''
|| gBNo
|| ''' AND A_ID = '''
|| g_id
|| ''' AND L_ID = '''
|| g_LId
|| ''' AND S_Code = ''C_3'' ';
execute immediate strquery; I have been asked to use a bind variable to avoid hard parsing.How do i do it?
Identical statements from this link : Parsing in Oracle — DatabaseJournal.com d. The bind variable types of the new statement should be of same type as the identified matching statement. i am getting confuse here .. when parsing occurs some links saying about bind variable.but official document never said about bind variables.
View 3 Replies View RelatedI created a "Select List" in the Shared Components area as follows:
My goal is to create a shared select list that can be used on any form for a particular Field.
IF :P10_FK_RSTA_CODE is NULL THEN
RETURN
'select col_description, col_code_pk
from CODE_TABLE
where col_active_ind = ''Y''';
[code].....
Which works great, but how can I make the select list work for the same column on a different form? Because :P10_FK_RSTA_CODE is hard-coded in the function, I can't reuse this Function from a different form. (I could rename the Field on every form to the same name, but I'm hoping there is a better way.)
Is there a way I can pass in a variable from the Field Item to make this dynamic where I can use it on any form?
I have to use bind variable for dynamic sql in a procedure. Is there a way to have control on these values. Say for example:

I have more than 5 In parameters, all 5 is not compulsory by default they are null and sql formation is also dynamic with in the procedure.I need to map bind variable to a proper one.. Is there a way to handle bind variable.

how to avoid the bind variable in view.
The query is correct but it contains bind variable Based on this query, View has to be created for report
like example select * from emp where deptno = :deptno
How to get the correct result by avoiding bind variable because view does not accept bind variable.
What is the difference between these two variables and their usage?

I have a problem when creating a dynamic statement. The problem is in the bind variable ':OLD.CUST_NAME' ,..my question is is there an escape character to treat the bind variable as a literal string?

The idea is to use some constant value in PL/SQL code with requirement to feed it to Oracle as value but not bind variable. Such constants used in multiple places in the code, so wants to declare it but from DB point of view it should be value. In my case Oracle will choose much better execution plan with real value for the table.
I tried to use constant, e.g:
CODEdeclare
const1 constant number := 1;

We are on oracle 10.2.0.4 on Solaris 10 and have a perf. issue with a bind variable using query. The query is in java application. I want to test its performance when the query doesn't use bind variable and instead uses the passed value as literal. How can it be done?
As example lets say the query is:
SQL> variable vn varchar2(20);
SQL> EXEC :vn :='ADAMS';
PL/SQL procedure successfully completed.
SQL> select * from emp where ename=:vn;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------
7876 ADAMS CLERK 7788 12-JAN-83 1100 20
1 row selected.
SQL> EXEC :vn :='KING';
PL/SQL procedure successfully completed.
SQL> select * from emp where ename=:vn;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------
7839 KING PRESIDENT 17-NOV-81 5000 10
1 row selected.
But the statements will be taken as similar statements by oracle (due to :vn). Now I want oracle to take it as literal and the change for this has to be done in java code in my actual scenario which has a different query (but conceptually it uses bind variable and I want it to use passed value as literal). How can it be done?
since the optimizer (during explain plan) assumes all bind variable to be of varchar type, while checking plan for SQL statement using bind variable of numeric and date type shall we convert (typecast) it as following?
variable n_sal number
variable dt_joining date
exec n_sal:= 1000
exec dt_joining := '12-dec-2005'
select first_name from emp_data where sal=to_number(n_sal) and joining=to_date(dt_joining);
I want to know what exact process happens in oracle architecture when an update query is fired.

Is it possible to hard code application server ip in oracle forms using plsql code. I am trying to open one form in my application but its giving me error as no data found. the application is using windows authentication. Unfortunately i don't have access to source code of the forms.
But i think there might be a possibility that application server/ db server ip might have hard coded in that forms so its may not be pointing to actual app server/db server.

I've a query that sum up data from one table. But I've to convert them into rows.
Summary query result.
COL1 COL2 COL3 COL4
1000 2000 3000 4000
Test Table creation script.
CREATE TABLE TEST_TBL
(
COL1 NUMBER(14,2),
COL2 NUMBER(14,2),
COL3 NUMBER(14,2),
COL4 NUMBER(14,2)
) ;
INSERT INTO TEST_TBL VALUES( 1000, 2000, 3000, 4000 ) ;
Expected result
A1 1000
A2 2000
A3 3000
A4 4000
A1, A2, A3, A4 are hard coded fixed values.
I could have done this but not a good idea in case table TEST_TBL is not a single row table but an inline query on 1,00,00,000 records with summary functions. In my table I've a summary query instead of single row table.
SELECT 'A1', COL1 FROM TEST_TBL
UNION ALL
SELECT 'A2', COL2 FROM TEST_TBL
UNION ALL
SELECT 'A3', COL3 FROM TEST_TBL
UNION ALL
SELECT 'A4', COL4 FROM TEST_TBL
