Denis,

Assure toi que si @patern est 10 de long que le champ contient '%A%%%%%%%%'
ce devrais fonctionner je l'utilise tout le temps.

Subject: SQL RPG Where clause question

Hello all,

I want to extract record from a file where a field matches a pattern. To do
so, I use the « like » instruction in the where clause. Here is a strip down
version:

@patern = '%' + %trim(@filter) + '%';
exec sql declare cur_next_filter cursor for
select ch1 from nozzzdp
where dsl like :@patern ;
...
exec sql fetch from cur_next_filter into :ds_key;

The value of the @filter variable is "A" (I want everything with an A in the
dsl vaviable)

This does not retrieve any value (sqlstt = 2000)

I then tried the following:

@patern = '''' + '%' + %trim(@filter) + '%' + ''''; exec sql declare
cur_next_filter cursor for
select ch1 from nozzzdp
where dsl like :@patern;
...
exec sql fetch from cur_next_filter into :ds_key;

I tough that maybe I needed the pattern string to be in quotes but no luck.

So, to make sure that there was no problem somewhere else, I tried:

exec sql declare cur_next_filter cursor for
select ch1 from nozzzdp
where dsl like '%A%' ;
...
exec sql fetch from cur_next_filter into :ds_key;

This works and returns some value.

Does that mean that I cannot use variable with the "like" statement when
using a cursor?

Any help will be appreciated
