Also, use the GET DIAGNOSTICS statement with the Message_text parameter. It
should give you a perfectly understandable message. I can't remember the
exact syntax off hand but you will find it in the archives.

One thing, Erick, those SQL statements don't need to be run Execute
Immediate, you get better performance just running the statement itself:

exec sql DROP ALIAS QTEMP/AA;
exec sql CREATE ALIAS QTEMP/AA FOR QTEMP/DISP(DISP);

But using embedded SQL, you need to "Select/Into/" some host variable. It
has to return one row only, but your statement does that.

exec sql SELECT MAX( LENGTH( TRIM(DISP) ) ) INTO :MyVar FROM QTEMP/AA

Where after executed, MyVar should have the value of the length of the
longest line.

I have a SQLPRGLE program compiled to a target release of V5R4M0
that works correctly in V7R1M0, but throws a SQL exception when
processing the prepare statement. The purpose of the
code is to simply find the longest line in the file.

/ Eval cmdSQL = 'DROP ALIAS QTEMP/AA';
/ exec sql Execute Immediate :cmdSQL;
/
/ Eval cmdSQL = 'CREATE ALIAS QTEMP/AA FOR QTEMP/DISP(DISP)';
/ exec sql Execute Immediate :cmdSQL;
/
/ cmdSQL = 'SELECT MAX( LENGTH( TRIM(DISP) ) ) FROM QTEMP/AA';
/ exec sql prepare s1 from :cmdSQL;

SQL values after processing the prepare statement:

sqlcod = 204
sqlerm =
....5...10...15...20...25...30...35...40...45...50...55...60
' *ALL *N MEM '
' '

Does anyone know if there is an issue with the above code?
