Re: SQL question with where in clause

Well, shoot... I think I had a similar kind of issue too. Check out this
site... maybe it can help you. I never did use the suggestions but it
might help. This, again, is using procedures. But maybe you can get
something out of it.

Hi
No the problem i have is, i dont know how many ? to be
added to my SQL statement
select * from mytable where line in (?,?,?)
will work if i know i will have only 3 values to
replace, but the number of lines selected are going to
come from the screen, which can be from 1 t more then
100, so i wanted to make this portion dynamic

I went back at old code... In places where didn't

cstmt.setNull( ... );

However, I wasn't doing this with a select statement
it was with a
procedure call that populated databases. But this
may be a place to start
looking at.

Without seeing your code... I believe you are

wanting to do this. Are
you

doing this?

value1 = 'ABC';
value2 = 'XYZ';
value3 = '';
value4 = '';
value5 = '';
value6 = '';
value7 = '';

sqlStatement = "{SELECT * FROM mytable WHERE line

in (?,?,?,?,?,?,?)});

cstmt = conn.prepareCall(sqlStatement);
cstmt.setString(1, value1);
cstmt.setString(2, value2);
cstmt.setString(3, value3);
cstmt.setString(4, value4);
cstmt.setString(5, value5);
cstmt.setString(6, value6);
cstmt.setString(7, value7);

I cannot test this right now, but this is how I

understand to use the "?"

place holders.

Hi
I have a sql statment like

select * from mytable where line in ('ABC',

'XYZ')

where this SQL statement is going to extact all

rows

where line is ABC and XYZ,

but now the problem is i do not know if there

are

going to be only one line or 2 or 10, so i

thought i

would define the sql as

select * from mytable where line in ?

and then i created a string like ('ABC', 'XYZ')

and

passed it as input parameter, but it does now

work,

Any ideas for a work around this solution
