A macro is a group of one or more SQL statements that are given a name and executed with a simple command. Macros ensure multiple SQL steps are not forgotten as the macro remembers them. When a macro contains multiple commands, Teradata treats them as a single transaction so either all the commands succeed or none of them do. A sample macro is provided that selects data from different tables and conditions in one transaction.

you want to ensure you don't forget an SQL
step you should use a macro.
The user sometimes forgets, but the macro
always remembers. Good one

If there are multiple commands, Teradata treats
them as one single transaction.
In other words, either they all work or none of
them work. Like views, the definition statement
for a macro is stored in the Data Dictionary.

4. Sample macro
CREATE MACRO Employee_mac AS
(
SELECT * from Employ1_v WHERE dept = 10;
SELECT * from Employ1_v WHERE dept = 20;
SELECT * FROM Employ1_v Order by lname;
);

5. Execute Macro
Execute Employee_mac;
