The SQLDA structure is supplied in both the sqlda.cpy (SQLDA only) and sqlda78.cpy (SQLDA plus SQLTYPE definitions) files, which by default are located in the %ProgramFiles(x86)%\Micro Focus\Visual COBOL\cpylib (Windows) or $COBDIR/cpylib (UNIX) directory.
You can include the SQLDA in your COBOL program by adding one or both of the following statements to your data division:
EXEC SQL INCLUDE SQLDA END-EXEC EXEC SQL INCLUDE SQLDA78 END-EXEC
