NEXT VALUE FOR

Available in: DSQL, PSQL

Added in: 2.0

Description

Returns the next value in a sequence. SEQUENCE is the SQL-compliant term for what InterBase and Firebird have always called a generator. NEXT VALUE FOR is fully equivalent to GEN_ID(..., 1) and is the recommended syntax from Firebird 2.0 onward.

Syntax

 NEXT VALUE FOR sequence-name

Example

 new.cust_id = next value for custseq;

NEXT VALUE FOR doesn't support increment values other than 1. If you absolutely need other step values, use the legacy GEN_ID function.
