You can create a stored procedure using either of the following:
- SQL CREATE PROCEDURE or REPLACE PROCEDURE statement in Teradata Studio Express.
- COMPILE command with the BTEQ utility.
The procedures are stored in the user database space as objects and are executed on the server.
The stored procedure definitions in the next examples are designed only to demonstrate the usage of the feature. They are not recommended for use.
Example: Defining a Stored Procedure for New Employees
Assume you want to define a stored procedure NewProc to add new employees to the Employee table and retrieve the name of the department to which the employee belongs.
You can also report an error, in case the row that you are trying to insert already exists, and handle that error condition.
The CREATE PROCEDURE statement looks like this:
CREATE PROCEDURE NewProc (IN name CHAR(12), IN number INTEGER, IN dept INTEGER, OUT dname CHAR(10)) BEGIN INSERT INTO Employee (EmpName, EmpNo, DeptNo ) VALUES (name, number, dept); SELECT DeptName INTO dname FROM Department WHERE DeptNo = dept; END;
This stored procedure defines parameters that must be filled in each time it is called.
