The DROP command removes an existing table (created as a result of a system dump) and all of its rows from the specified database on the Teradata system.


DROP [ database. ] table ;

Syntax Elements

Name of the database in which the table resides. If the database is not specified, the currently set database is assumed. Use a period (.) to separate the database name from the table name.
Name of the table to be dropped.

Usage Notes

The DROP command removes the specified table and any tables with the same name that end with a _C, _L, or _M suffix.

In general, enter a DROP command before performing a load operation to remove any existing tables that might have the same name as the table specified on the next LOAD command.

To use the DROP command, you must have the DROP privilege on the specified table.

Example: Dropping a system dump table

Assume that Crash_20000407_1013_02, Crash_20000407_1013_02_C, Crash_20000407_1013_02_L, and Crash_20000407_1013_02_M tables were produced as an result of the previous load operation.

To drop all four tables from the Crashdumps database, type the following:

DROP Crash_20000407_1013_02;

The following appears:

*** Dropping table Crash_20000407_1013_02;

Dul displays additional messages if you abort the load operation because it tries to dump tables used by the FastLoad utility even if they do not exist.
