EXECUTE IMMEDIATE
Performs a simple SQL execution without SQL parameters or result set.
Syntax
EXECUTE IMMEDIATE sqltext- sqltext is a string expression containing the SQL statement to be executed.
Usage
The EXECUTE IMMEDIATE instruction passes an SQL statement to the database server
for execution in the current database connection.
The SQL statement used by EXECUTE IMMEDIATE must be a single statement without
SQL parameters and must not produce a result set.
This instruction is equivalent to PREPARE,
EXECUTE and FREE done in one step.
Unlike the EXECUTE instruction, EXECUTE IMMEDIATE has no
USING clause (to specify SQL parameters), nor does it support an
INTO clause (to fetch values into variables). When specifying a
USING keyword after the string containing the SQL statement, the compiler will
consider this as the USING formatting
operator.
Example
MAIN
DATABASE stores
EXECUTE IMMEDIATE "UPDATE tab SET col='aaa' WHERE key=345"
END MAIN
