acc_column_spec 

Syntax

<acc_column_spec> ::= <key_column_spec> | <simple_column_spec>

Use

This is a syntax rule for describing columns.

You use it in a DATAUPDATE command to define whether the qualification columns are key columns or non-key columns of the target table.

If you use key columns as qualification columns (key_column_spec), each data record in the source file updates that line in the target table that matches the specified key.

DATAUPDATE TABLE customer
KEY cno 01-04
SET place 05-16
INFILE 'customer.data' FORMATTED

If you use non-key columns as qualification columns (simple_column_spec), each data record in the source file updates each line in the target table that is identified with the value(s) of the qualification column(s).

DATAUPDATE TABLE customer
place 1
SET zip 2
INFILE 'customer.data'
