The NULL specification identifies the character or a string of characters that BTEQ uses to represent null value fields in the reported results for a data-returning SQL request. The BTEQ NULL specification can range from 1 to 253 characters. The default value is a single question mark character.

Example – NULL

.SET NULL AS '---'
