RE: A problem in embedded SQL

Charles,

I don't think this is the problem. It is a prepared statement dynamic execution and the sql statement that I provided is the exact same statement that both programs execute. And I do trim the blanks from the field.

Thanks,

Show the actual RPG code...

Assuming it looks like
myiccode = 'EAPP%';
myccomm = '%81925B%';

exec sql;
SELECT ipol#
FROM commcmtp
join commitmp on ccomp=icomp
and ipol# = cpol#
and cseq = iseq
and iccode like :myiccode
and crecid = 1
and ccomm like :myccomm;

Then the problems is likely that the variables are fixed length...resulting
in an actual search value of 'EAPP% '

Easiest fix, change the variables to varchar.
Alternatively, load '%' all the way to the end of the variables, 'EAPP%%%%%'

I am working on a program that is supposed to return a data element
when the user requests it is using two parameters.

The problem is in the RPGLE (running under 7.1) the sql statement
returns EndOfData when I attempt to use the program with parameter
that I know is there. But if I take the sql statement and use
interactive sql, it works and selects the correct record.

I don't understand what the difference is between the two methods.

The sql statement is:

SELECT ipol#
FROM commcmtp
join commitmp on ccomp=icomp
and ipol# = cpol#
and cseq = iseq
and iccode like 'EAPP%'
and crecid = 1
and ccomm like '%81925B%'

In the RPGLE, it is a prepared statement that is okayed by the prepare
statement. It is okayed by the open statement. But the fetch statement
returns EndOfData.

Taking the same sql statement and executing it in interactive sql, it
works properly and returns the expected data element.

Can anyone give me a clue why it doesn't work in RPGLE?
