An UPSERT statement updates an existing record or creates a new record if an existing record is not identified.

UPSERT Syntax

The UPSERT syntax is the same as for INSERT. NetSuite uses the input provided in the VALUES clause to determine whether the record already exists. If the record does not exist, all columns required to insert the record must be specified. See Data Model for any table-specific information.

UPSERT INTO <table_name> 
( <column_reference> [ , ... ] )
VALUES 
( { <expression> | NULL } [ , ... ] ) 
  

<expression> ::=
  | @ <parameter> 
  | ?
  | <literal>
