Example: Locator Mode Processing of a Large Object - Teradata Database - Teradata Vantage NewSQL Engine

The first example shows how locator b is used to copy an existing, Teradata platform-resident BLOB from its current base table location into a base table named mytable without any data transferred to the client.

     USING (a INTEGER,
            b BLOB AS LOCATOR)
     INSERT INTO mytable VALUES (:a, :b);

The second example shows the BLOB data identified by locator b being returned to the client.

     .SET INDICDATA ON
     .EXPORT INDICDATA FILE=udbsales.dat

     USING (b BLOB AS LOCATOR)
     SELECT :b;

     .EXPORT RESET
