I would like to set the DB2 table name as a variable. In the example below, I need to declare two variables, TABLE1 and TABLEA with the same value ('USERA.TABLEXYZ'). Can a single variable be used?

Code:

DCL SqlCmd CHAR(100) VARYING INIT(' ');
DCL TABLE1 CHAR(25) VARYING INIT('USERA.TABLEXYZ');

/* Declare pre-processor variable */
%DCL TABLEA CHARACTER;
%TABLEA = 'USERA.TABLEXYZ';
...
....
SqlCmd = "Select from " || TABLE1 || "..."
EXEC SQL SELECT COL1, COL2 INTO :COLA, :COL2 FROM TABLEA
  WHERE .....;

danm,

Why define the tablea and table1? Dynamically prepare the SQLCMD and use the table name.

or just define 1 variable and move the table name into it.
