Your ESL program may require SQL statements other than SELECT,, UPDATE, INSERT, or DELETE. For example, you may need to build SQL Data Definition Language (DDL) statements, such as CREATE TABLE and DROP, or SQL Data Control Language (DCL) statements, such as GRANT and REVOKE.
To create a DDL or DCL statement in DB/Assist, you must specify the statement type as Other in the New SQL Statement dialog box.
Then, to build an Other type SQL statement, you can do either of the following:
•Import the statement into DB/Assist from the clipboard or a file, as described in Importing a Statement into DB/Assist.
•Type the statement in the SQL Editor window, as described in Typing a Statement in the SQL Editor Window.
The following table lists the specific SQL statements that you can create in DB/Assist as an Other type. (For information about the syntax of these statements, refer to the IBM Structured Query Language (SQL) Documentation.)
