Examples - Teradata Vantage - Analytics Database

Example: CLOB Data Type

The following example creates a table that defines a CLOB column named clarge:

CREATE TABLE t1
  (id INTEGER
  ,clarge CLOB(2K) CHARACTER SET UNICODE);

Analytics Database stores the character data using the UNICODE server character set.

Example: Inserting CLOB Data

The following example shows a stored procedure that inserts part of a CLOB into one table and the remaining part of the CLOB into another table:

CREATE TABLE LocalData(ld_ID INTEGER, ld_DATA CLOB);
CREATE TABLE GlobalData (gd_ID INTEGER, gd_DATA CLOB);

CREATE PROCEDURE DataSplitter(IN local_ID  INTEGER,
                              IN global_ID INTEGER,
                              IN all_DATA  CLOB)

BEGIN

   INSERT LocalData (local_ID, SUBSTRING(all_DATA FROM 1 FOR 128546));
   INSERT GlobalData (global_ID, SUBSTRING(all_DATA FROM 128547));

END;
