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 to build sql query for view object at run time

Hi,
I have a LOV on my form that is created from a view object.
View object is read-only and is created from a SQL query.
SQL query consists of few input parameters and table joins.
My scenario is such that if input parameters are passed, i have to join extra tables, otherwise, only one table can fetch the results I need.
Can anyone please suggest, how I can solve this? I want to build the query for view object at run time based on the values passed to input parameters.
Thanks
Srikanth Addanki

As I understand you want to change the query at run time.
If this is what you want, you can use setQuery Method then use executeQuery.

Thanx in advanceArrggh. I wish people wouldn't just answer a question without taking the time to actually think about what the user is asking for and if it makes sense. I like Diney's response best: Why not use the Title View? (i.e., asking questions until it is clear what is needed.) So along those lines, why are you trying to put the name of your report in a column of your report?? And why do you need to use direct sql to do this??
Kindly or not, urgent or not, state what you are trying to achieve and why you need it (if the obvious answer like "using the Title View" doesn't work for you), instead of simply assuming your method is right and you need to know how to do what envision. Your method may not be correct or necessary.

Please note : This sql query is running perfectly in sql server. Query have no errors. Please check whats wrong with my time schedular. I just want my schedular to run every 10 seconds regardless of date.

Hi Emad,
Is your script in a ".sql" file? May I know how you configure the schedule task action?
Since you didn't mention how you configure the schedule task, can you confirm you have followed the below step correctly?
Save your script in a ".sql" file.
Create a ".bat" file and call the sql file above inside with
sqlcmd.exe, you can reference
here.
Configure a schedule task to run the ".bat" file in a certain interval.
Have you tried to run the script in you bat file in a standalone commandline window? Please post the script in your bat file, It can help to diagnose the issue.
If you have any question, feel free to let me know.
