SQL Query: Accumulate a column

thread526-5819

SQL Query: Accumulate a column

SQL Query: Accumulate a column

(OP)
Hallo, could somebody help me in this SQL-Problem?    

My table contains the following columns:
Invoicenumber / Articlenumber / Quantity / Text

Records should be added in the column Quantity, when the Invoicenumbers are identical and Articlenumber are identical.

Example:
INVNO / ARTNO / QUAN / TEXT
4711 / 312 / 3 / Table
4711 / 434 / 6 / Chair
4711 / 312 / 2 / Table
4712 / 312 / 7 / Table

The result should be:
4711 / 312 / 5 / Table
4711 / 434 / 6 / Chair
4712 / 312 / 7 / Table

Thanks for help
Didi
