Using bind variables in Oracle SQL developer

Hi all,
i am using Oracle SQL developer. i want to use the bind variable in my sql.
variable myid number :=1;
select * from mds_3618_request where id = :myid;
but i am getting the below error.
Error starting at line 2 in command:
select * from mds_3618_request where id = :myid
Error report:

Using DEBUG Mode in Oracle SQL Developer Data Modeler to Log SQL

Hello,
I am looking for the possibilty to enable the logging of SQL in Data Modeler.
Jeff Smith wrote an article how to do this for SQL Developer, for Data Modeler there are other configuration files. Does anyone have an idea?
Best regards,
Joop

Hello Philip,
the URL to the article of Jeff is: http://www.thatjeffsmith.com/archive/2012/10/using-debug-mode-in-oracle-sql-developer-to-log-sql/
in the install directory of Data Modeler 3.3.0.734 exists a file datamodeler\datamodeler\bin\datamodeler.conf. This analogue the situation for sql Developer.
However in this file there is no reference to a (non)debug file.
In ide/bin directory there is a ide-logging-debug.conf and ide-logging.conf file. But they are not referenced. Should one of them be included?

Declare, Set, and Use a variable in a SQL Developer Query

I come from the SQL Server world and am trying to do something very simple: Declare, set, and use a variable in a query. For example:
Declare @lastPeriod date;
Set @lastPeriod = (select max(payperiod) from table 1 where payperiod < current_date);
Select field 1,
Field2
From table2
Where payperiod = @lastPeriod
The variable is going to be used in more areas in the query which is why I am simply not using a Sub-query in the where clause. I appreciate any assistance.

This forum is for issues with the SQL Developer tool. You'd get more response in the SQL And PL/SQL forum.
That said, read up on bind variables and substitution variables.
Whenever you can you should use Bind variables (e.g. *:lastPeriod* ), as they increase performance. In sqldev, there's no need to declare as you will be prompted to enter them on execution (F9), but you do if you execute as script (F5) (e.g. VARIABLE lastPeriod VARCHAR2(30);).
Alternatively, Substitution variables (e.g. *&lastPeriod* ) will literally be substituted in your statement before the database parses it. In sqldev, there's no need to declare as you will be prompted to enter them on execution (either F9 or F5), but you can (DEF lastPeriod='TEST'; ).
Have fun,

How do I use bind variables for the SQL statements having IN clause

SELECT id, name FROM t
WHERE id in (10,20,30)
As the IN list will have 'n' number of values, I am not able to specify fixed number of bind
variables like
SELECT id, name FROM t
WHERE id in (?,?,?....)

Set indention / tab size in Oracle SQL Developer

I've been poking around for an hour. Can't figure this out.
Where, either on the app's UI or in the "product-preferences.xml" file, can I change SQL Developer's indention (tab) size to 3? My organization uses PowerBuilder, and when I copy+paste our PB SQL (which uses leading tabs) into Oracle SQL Developer, it looks like crap. It would really help if I could change the code editor to a tab size equivalent to three spaces.
And no, we can’t use spaces. :-)
Thanks!
(maybe SQL Developer 2 could have a tab size field in “Preferences”)

In 1.5.x, it's under Preferences - Database - SQL Formatter - Alignment and Indentation .
However, at least in the current 1.5.3, a bug ignores the tab preferences completely, so you're stuck with the 2 spaces. If you can't wait until this gets fixed (with luck in the upcoming 1.5.4 or else maybe by 2.0), revert to an earlier version.
Regards,
K.

Using bind variables with sql statements

We connect from a VB 6.0 program via OO4O to an Oracle 8.1.7 database, using bind variables in connection with select statements. Running ok, but performance again by using bind vars not as good as expected!
When looking into the table v$sqlarea, we were able to detect the reason. We expected that our program submits the sql statement with bind vars, Oracle parses this once, and with each select statement again, we do not have a reparse. But: It seems that with each new session Oracle reparses the sql statement, that is, Oracle is not able to memorize or cache bind vars and statements. Even more worrying, this kind of behaviour was visible with each new dynaset, but the same database/session.
Is there anybody our there with an idea of what is happening here?
Code snippet:
Dim OraSession As OracleInProcServer.OraSessionClass
Dim OraDatabase As OracleInProcServer.OraDatabase
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
Set OraDatabase = OraSession.OpenDatabase(my database", "my connect", 0&)
OraDatabase.Parameters.Add "my_bind", 0, ORAPARM_INPUT
OraDatabase.Parameters("my_bind").DynasetOption = ORADYN_NOCACHE
OraDatabase.Parameters("my_bind").serverType = ORATYPE_NUMBER ' Bind Var Type
Dim RS As OracleInProcServer.OraDynaset
strSQLstatement= "Select * from my_table where igz= [my_bind] "
Set RS = OraDatabase.CreateDynaset(strSQLstatement, &H4)
OraDatabase.Parameters("my_bind").Value = myValue
RS.Refresh
Cheers and thanks a lot :)

ORA-01006 Using Bind Variables In A Dynamic SQL Contains Query

I have the following dynamic SQL query :-
declare
TYPE typ_sql IS REF CURSOR;
ltyp_sql typ_sql;
lv_sql VARCHAR2(100);
begin
lv_sql := 'SELECT arx_id FROM arx WHERE CONTAINS ';
lv_sql := lv_sql || (arx_full,''(:b1) WITHIN ui'') > 0';
open ltyp_sql FOR v_sql USING ln_id;
fetch ......
close ......
end;
When the code tries to open the cursor it gives the above error. I presume it is the way Oracle is expanding the bind variable but I cannot find anything in the docs to say why this is happening or whether you can do this or not using bind variables ( CONTAINS query ). Any help would be appreciated, thanks,
Stuart.

lv_sql || '(arx_full, :b1 || '' within ui'') > 0';

PL SQL using bind variables

I am very much new to PL/SQL to pardon my neivte.
I would like to have some PL/SQL code that uses
bind variables for insert statements and than issue
commit's after a specific number of inserts.
For example.
desc xxx.taba
a number
b varchar2(20)
I want to do someting like this:
declare
l_start number default dbms_utility.get_time;
create or replace procedure insert_xxx(commit in number)
begin
for i in 1 .. 1000
loop
:a:=i;
:b:=dbms_random.string('P', 20);
intert into xxx :a :b;
if i/mod=(number passed into to proc)
commit
end loop;
dbms_output.put_line
(round((dbms_utility.get_time-l_start)/100, 2) ||
' Seconds...' );
end;
end;
Can somebody help me out with the correct syntax
as I know it's incorrect.

A few remarks
- procedures don't have hidden variables defined in the outside world, as procedures are black boxes, which communicate only with the outside world
using the actual parameter list
- procedures don't commit. The caller should always commit!!!
- procedures don't commit every <n> records. A commit finalizes a logical unit of work, not a technical one.
If I would have been your supervisor and you would have presented this code, I would have fired you on the spot.
Committing inside a loop also increases the likelihood of ora-1555 errors.
So: remove the current parameter
a and b should be formal parameters of the procedure
Inside the procedure it should read
insert into xxx values (a, b)

Possible for Oracle to consider constraints when using bind variable?

Consider the following table with a check constraint listing the possible values of the column
create table TEST_TABLE(
my_column varchar2(10));
insert into TEST_TABLE select 'VALUE1' from dba_objects;
alter table TEST_TABLE
add constraint TEST_TABLE_CHK1
check (my_column in ('VALUE1', 'VALUE2'));
begin dbms_stats.gather_table_stats(ownname=>user,tabname=>'TEST_TABLE');END;Let's see the number of logical I/O's needed for the following SQL statements.
(The value was obtained by the delta ofselect m.value from v$mystat m, v$statname n
where name='session logical reads' and m.statistic#=n.statistic#)
If string lateral is used:
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE1';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE2';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE3';
end;
Consistent Gets: 0Oracle can eliminate the table if it knows the queried value can't satisfy the constraint. Good.
(Actually, the execution plan for the last query included the 'FILTER' operation.)
However, if bind variable is used:
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE1';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE3';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21Oracle can't eliminate the table using the constraint. I can understand that because bind variables are used, Oracle can't directly eliminate the table when generating the execution plan. However, is it possible to eliminate the table, or at least employ some shortcut in runtime? If not, will this be a performance loss compared with using values laterals when check constraint exists?
(And is it possible to use autotrace on PL/SQL block in sqlplus?)
Oracle:
     10.2.0.4 SE
     11.2.0.2 SE
OS:
     RHEL5

However, is it possible to eliminate the table, or at least employ some shortcut in runtime? I can't see how to do this. Oracle has a sqltext that has an embedded bind variable in it. And for this sqltext it has an execution plan in the shared pool that will be used irrespective of the actual bound values at runtime.
Maybe in 11G, with adaptive cursor sharing / plan bind awareness, Oracle might be smart enough to introduce a second execution plan for the VALUE3 case.
If not, will this be a performance loss compared with using values laterals when check constraint exists?Only if you submit the dumb query and search for records with VALUE3... Normally your application code would not hold/generate these queries.
Will it?
For columns whose values are bound by a CHECK constraint, one might even consider to never use bind variables, since very likely you will have few versions of queries that use these columns.
Not?

Does Oracle E-business suite R12 use bind variables?

Hello,
We have Oracle E-business suite R12 and database 10.2.0.3.
I was just wondering does E-business suite R12 use bind variables?
We have recently purchased Toad and Spotlight, in Spotlight we keep getting an alarm raised for Parse SQL requests (Library cache latches alert) When I've researched into this the recommendation is to try to improve the use of bind variables within your application.
Please could someone help me answer this?
Thank you
Sarah

Hi,
I was just wondering does E-business suite R12 use bind variables? Yes it uses bind variables. You can trace a concurrent program and get the tkprof to check it.
We have recently purchased Toad and Spotlight, in Spotlight we keep getting an alarm raised for Parse SQL requests (Library cache latches alert) When I've researched into this the recommendation is to try to improve the use of bind variables within your application.You can not make every conc. program or sql use bind variables. Some times it is not possible so.
Thanks

Help setting Parameters using JDBC and Bind Variables for Oracle List

I fully understand the concept of using Bind Variables when using JDBC to avoid hard parses everytime my SQL statement is executed when only a certain value changes. For example, perhaps I have the following statement:
PreparedStatement ps = con.prepareStatement("select salary from employees where employee_id = ?");
I would then set the value of the question mark (the first and in this case only parameter) using:
ps.getStmt().setString(1,empId1);
That is assuming I have the variable empId1 populated with what I want. Anyway, my question has to do with Oracle lists. In other words, if I am just executing the statement against the db, it might look like:
select salary from employees where employee_id in ('123','456','789');
I still want to use bind variables and I can do it in JDBC with something like:
select salary from employees where employee_id in ('123','456','789');
ps.getStmt().setString(1,empId1);
ps.getStmt().setString(2,empId2);
ps.getStmt().setString(3,empId3);
BUT, what if I just want to construct my list of ids upfront as a string and do something like:
select salary from employees where employee_id in (?)
ps.getStmt().setString(1,listOfEmpIds);where listOfEmpIds would look something like '123','456','789'.
That's what I want to do but it doesn't work. It would be treating the list as a single parameter as opposed to lots of individual parameters. Can someone please tell me the syntax for this if it is possible? I have tried where XX in (?) and where XX in ? (and the string I substitute has the parenthesis in it), but neither work.
Thank you for your help.

I always build the list myself.
You could, however, pass the list as a varchar to a stored proc and then have the stored proc parse (or dynamically execute) using it.
The second method might even be faster although I would suspect that is only going to be the case if the list is very large. Or it might not.
