If you are just trying to execute an SQL statement, key the SQL into a source
member, replacing the usual : in front of the parameter names with an ampersand
(&) so that it looks just like a CL variable, and run CRTQMQRY to create a
query management query. You can execute this with STRQMQRY, which allows you to
pass parameters in from CL. If a parameter is numeric, just pass the variable.
If it is alpha, you will need to concatenate tic marks around it as in CHGVAR
VAR(&PARMVAL) VALUE('''' *CAT &ALPHAVAR *TCAT ''''). If you're trying to run a
query (IBM Query program product), you can do the same by specifying
ALWQRYDFN(*YES) for the STRQMQRY command. In the query itself, declare a
variable which specifies the record selection value as if it were a literal,
prefixing the name with a colon(:), just as you would if you were coding an
embedded SQL command. When you try to save the query, you will be prompted for
the name of the record selection query. Just make something up. It is not
validated, and the name will not be used.
