Sends each SQL statement to the database at compilation time.
CHECK requires that you also:
- Set the DB compiler directive option, or identify the database using the DB2DBDFT environment variable.
- If the connection to the database specified requires authentication, then the PASS compiler directive option is also required.
- When using SQL(CHECK) with an ODBC connection to Oracle, you must have at least the same user privileges as are required to
execute the SQL statements in the program.

Depending on your driver and/or DBMS and in certain circumstances, CHECK does not flag invalid SQL statements.
You can specify the [NOCHECK], [ALSO CHECK], or [WITH CHECK] statement prefix to affect specific SQL statements. See
SQL Statement Prefixes for CHECK Directive for complete information.
Important: For applications that use JDBC with the JVM Managed Runtime, be sure that your environment is configured appropriately. Otherwise,
compilation could fail. See
To create a JVM COBOL project for JDBC and
Configuring the JDBC Run-time Environment for details.
