If yout need post-query for filling descriptive colums (eg. department name in emploees) you should build a view object which includes the descriptive colums by joining the relevent tables

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:

How to create sql query for item master with operator LIKE with variables?

hi all,
How to create sql query for item master with
operator LIKE(Contains,Start With,End With) with variables using query generator in SAP B1 ?
Jeyakanthan

Hi Jeyakanthan,
here is an example (put the like statement into the where field)
SELECT T0.CardCode, T0.CardName FROM OITM T0 WHERE T0.CardName Like '%%test%%'
The %% sign is a wildcard. If you need start with write 'test%%' and otherwise ends with '%%test'. For contains you need '%%test%%'. You also could combinate this statements like 'test%%abc%%'. This means starts with test and contains abc.

How to write sql query for counting pairs from below table??

Below is my SQL table structure.
user_id | Name | join_side | left_leg | right_leg | Parent_id
100001 Tinku Left 100002 100003 0
100002 Harish Left 100004 100005 100001
100003 Gorav Right 100006 100007 100001
100004 Prince Left 100008 NULL 100002
100005 Ajay Right NULL NULL 100002
100006 Simran Left NULL NULL 100003
100007 Raman Right NULL NULL 100003
100008 Vijay Left NULL NULL 100004
It is a binary table structure.. Every user has to add two per id under him, one is left_leg and second is right_leg... Parent_id is under which user current user is added.. Hope you will be understand..
I have to write sql query for counting pairs under id "100001". i know there will be important role of parent_id for counting pairs. * what is pair( suppose if any user contains both left_leg and right_leg id, then it is called pair.)
I know there are three pairs under id "100001" :-
1. 100002 and 100003
2. 100004 and 100005
3. 100006 and 100007
100008 will not be counted as pair because it does not have right leg..
But i dont know how to write sql query for this... Any help will be appreciated... This is my college project... And tommorow is the last date of submission.... Hope anyone will help me...
Suppose i have to count pair for id '100002'. Then there is only one pair under id '100002'. i.e 100004 and 100005

Sounds like this to me
DECLARE @ID int
SET @ID = 100001--your passed value
SELECT left_leg,right_leg
FROM table
WHERE (user_id = @ID
OR parent_id = @ID)
AND left_leg IS NOT NULL
AND right_leg IS NOT NULL

How does a SQL query work

Hi all...
How does a SQL query basically work? Is there any pseudocode for it?
How ro calculate the cost of query?
Can we find out what would be the execution time for a query before it is executed?
Thanks in advance.
Ameya

Hi Avinash,
Look closely mate!!!
You have done set autotrace on... meaning you are executing the statement while i am doing set autotrace traceonly explain meaning the statement would never get executed actually.. oracle optimizer will just select the desired plan and will show the output..
You can even ESTIMATE how many rows the qeury will return before even executing the statement using the same above tech.. i will show you how:
The explain plan gives this -- as long as you are using the CBO (cost based
optimizer). Doesn't matter if you have 1 or 50 tables. The last part of the
plan is the estimate output.
consider:
SQL> set autotrace traceonly explain
SQL> select e1.*, e2.* from emp e1, emp e2;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=15 Card=196 Bytes=12544)
1 0 MERGE JOIN (CARTESIAN) (Cost=15 Card=196 Bytes=12544)
2 1 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=448)
3 1 SORT (JOIN) (Cost=14 Card=14 Bytes=448)
4 3 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=448)
196 = 14 * 14 -- thats right....
SQL> select emp.ename, mgr.ename from
2 emp, emp mgr
3 where emp.mgr = mgr.empno;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=5 Card=13 Bytes=208)
1 0 MERGE JOIN (Cost=5 Card=13 Bytes=208)
2 1 SORT (JOIN) (Cost=3 Card=14 Bytes=112)
3 2 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=112)
4 1 SORT (JOIN) (Cost=3 Card=14 Bytes=112)
5 4 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=112)
Here is estimated that about 13 rows would be returned...
SQL> select count(*) from emp;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=1 Card=1)
1 0 SORT (AGGREGATE)
2 1 INDEX (FULL SCAN) OF 'EMP_PK' (UNIQUE) (Cost=1 Card=14)
one row...
SQL> select ename, dname
2 from emp, dept where emp.deptno = dept.deptno;
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=5 Card=14 Bytes=252)
1 0 NESTED LOOPS (Cost=5 Card=14 Bytes=252)
2 1 TABLE ACCESS (FULL) OF 'DEPT' (Cost=1 Card=4 Bytes=44)
3 1 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=14 Bytes=98)
14 rows...
1 select ename, dname
2* from emp, dept where emp.deptno = dept.deptno and emp.ename like '%A%'
SQL> /
Execution Plan
0 SELECT STATEMENT Optimizer=CHOOSE (Cost=2 Card=1 Bytes=18)
1 0 NESTED LOOPS (Cost=2 Card=1 Bytes=18)
2 1 TABLE ACCESS (FULL) OF 'EMP' (Cost=1 Card=1 Bytes=7)
3 1 TABLE ACCESS (BY INDEX ROWID) OF 'DEPT' (Cost=1 Card=4 Bytes=44)
4 3 INDEX (RANGE SCAN) OF 'DEPT_IDX' (NON-UNIQUE)
1 rows.....
and this was all done without executing the query. See EXPLAIN plan and the
PLAN_TABLE.

How Can I Execute Sql Query in Managed bean?

Hi,
I want to execute sql query in managedbean and get the query result. How can I do?
Best wishes!

You can do this by having current Database connection your application is using like this
public static synchronized DBTransaction getDBTransaction(){
FacesContext ctx = FacesContext.getCurrentInstance();
ValueBinding vb = ctx.getApplication().createValueBinding("#{data}");
BindingContext bc = (BindingContext)vb.getValue(ctx.getCurrentInstance());
DataControl dc = bc.findDataControl("AppModuleDataControl");
ApplicationModuleImpl am = ((ApplicationModuleImpl)(ApplicationModule)dc.getDataProvider());
return am.getDBTransaction();
and then user DBTransaction object to create Statement and PreparedStatement you can find those in java doc.

SQL query in managed bean

hi
i have some idea about setwhereClause() method ..... but in my case i want to use one SQL query (select * from tab )...i dont know how to use ....
(without view object we cant use setwhereclause() method thatsy i have to use sql statement in managed bean ........)
thanks in advance

First of all, you don't want to have any SQL in a managed bean. Managed beans are part of the View layer, and the query should be part of the Model. So what you want to do is add some code to your Model project. So you are trying to do "SELECT * FROM tab". Why not just create a read-only View Object (VO) for the query in the Model (assuming that you are using ADF BC).
Now as for setWhereClause - what do you need in your where clause? You can add where clauses to the query that defines your VO, without needing to resort to using this method. You can even add bind variables for the where clauses, and just drag the ExecuteWithParams method onto your pages, which will give you a place to set the bind variables before executing the query.
You can create your own method in the VO's implementation class, in which you may call setWhereClauseParam to gain more control over how the bind variables are set. Then you make the method available as an operation in the data controls by making it an exposed method to the client interface. You can use setWhereClause in such a method if you need to do so, but there are good performance reasons not to do so if a bind variable will do the job. setWhereClause can also set you up for SQL Injection attacks on your application's security.
