Teradata Database Reserved Words As with all database products, Teradata database has reserved words that cannot be used in SQL queries. For example, YEAR is a reserved word. These reserved words cannot be used as table or column names. Below is a list of all of the reserved words in Teradata. The textbooks and data sets for the textbooks were written without the reserved words in mind. Consequently, it has been necessary to rename some of the tables and columns. The database descriptions list changes to table and column names. Also, you can use the tree on the left-hand frame of Teradata SQL Assistant to see the new names that are used. You must use the new names in your SQL queries.
