Deallocates a dynamic SQL statement that was prepared in a prepare statement.
exec sql [at connection_name] deallocate prepare statement_name end-exec
The identifier assigned to the dynamic SQL statement when the statement was prepared.
EXEC SQL BEGIN DECLARE SECTION END-EXEC.
01 CMDBUF PIC X(120).
01 STATE PIC X(3).
EXEC SQL END DECLARE SECTION END-EXEC.
...
* The 'select into table' statement returns no results
* to the program, so it does not need a cursor.
MOVE "select * into tmp from authors where state = ?"
TO CMDBUF.
DISPLAY "STATE ? ".
ACCEPT STATE.
EXEC SQL PREPARE dynstmt FROM :CMDBUF END-EXEC.
EXEC SQL EXECUTE dynstmt USING :STATE END-EXEC.
EXEC SQL DEALLOCATE PREPARE dynstmt END-EXEC.
EXEC SQL COMMIT WORK END-EXEC.
A statement must be prepared before it is deallocated. Attempting to deallocate a statement that has not been prepared results in an error.
statement_name must uniquely identify a statement buffer and must conform to the SQL identifier rules for naming variables. statement_name can be either a literal or a character array host variable.
The deallocate prepare statement closes and deallocates any dynamic cursors declared for statement_name.
WARNING! If you are using persistent binds in your Embedded SQL program, use the deallocate prepare statement carefully. Needlessly deallocating prepared statements can negate the advantage of persistent binds.
