Example 1: Using EXECUTE to Create and Drop a Table

Example 2: Using EXECUTE to Produce a Result Set

Syntax

EXECUTE(native-syntax) BY catalog;

Arguments

native-syntax

specifies a native SQL query that can be run on the catalog’s driver. The EXECUTE statement accepts statements that produce a result set, as well as statements that do not produce a result set.

Restriction	PROC FEDSQL does not support native syntax that contains embedded bare semicolons. You can, however, use the FedSQL language processor to run these statements.
Note	The SQL statement might be case-sensitive, depending on your data source, and it is passed to the data source exactly as you enter it.

catalog

specifies the name of a catalog in the existing FedSQL connection.

Details

The EXECUTE statement is the only way that FedSQL provides to submit native SQL statements that do not produce a result set to a DBMS. Native SQL can be used in the following statements: DDLs, UPDATE, SELECT, and bulk loads.

A native connection for HDMD is a FedSQL connection.

Examples
