John,

Here's how to use a correlational UPDATE command in R:BASE:

Goal:

Update TableA (TableAColumn) from the SUM of values in TableB (TableBColumn)

Assumptions:

Both columns in each table are of similar data type, such as, BIGNUM, CURRENCY,
DOUBLE, INTEGER, NUMERIC, or REAL.

Command:

SET FEEDBACK ON
UPDATE TableA SET TableAColumn = (SUM(TableBColumn)) +
FROM TableB,TableA WHERE TableA.KeyColumn = TableB.KeyColumn
SET FEEDBACK OFF

That's all there is to it!

Very Best R:egards,

Razzak.
