Subj:   CONVERTING NULLS
 
From:   Nick Druga

Does anyone know how to change all NULL values in all fields to a space, zero or some date (depending on existing format) without updating each field, one at a time?

/* RECORD_ID is CHAR */
UPDATE td_table
   SET RECORD_ID   = ' '
 WHERE RECORD_ID   IS NULL;

/* PROCESS_NUM is INTEGER */
UPDATE td_table
   SET PROCESS_NUM = 0
 WHERE PROCESS_NUM IS NULL;

/* DATE_FILLED is DATE */
UPDATE td_table
   SET DATE_FILLED = DATE '0001-01-01'
 WHERE DATE_FILLED IS NULL;

.
.
.
etc.
