Kwesi writes "How do I populate a new field (or column) in an existing table using a select statement from another table. the select statement returns over 3,000 records from the original table.

In my where clause I'm using a common field (PdtID)in both tables to insert the new records.

Both tables are in different databases.

DATABASE VERSION: SQL 2000

My Code:

Update Database1.owner.TableToBeUpdated.FieldName
Set Database1.owner.TableToBeUpdated.FieldName =

SELECT Database2.owner.TableWithOriginalData.DataFieldName
FROM Database2.owner.TableWithOriginalData INNER JOIN
Database2.owner.AnotherTable ON
Database2.owner.TableWithOriginalData.DataFieldName = Database2.owner.AnotherTable.Fieldname

Where Database2.owner.TableWithOriginalData.PdtID = Database1.owner.TableToBeUpdated.PdtID"

FROM Database2.owner.TableWithOriginalData dt1 INNER JOIN
Database2.owner.AnotherTable dt2 ON
dt1.DataFieldName = dt2.Fieldname
and dt1.TableWithOriginalData.PdtID = dt2.TableToBeUpdated.PdtID
