Hi,

i got two tables, same structure table "028 - des" and table "028 -
prg".The table "028 - prg" is in my databese application but the "028
- des" is the newest.I can't replace table "028 - prg" with "028 -
des" 'cause in any case i need to modify other stuff.i have to find
difference beetwen the tables.

There are in the two tables the same names of the fields an structure
and you can see it on the attachments.

1)the problem is that i don't know how manage a multifields with multi
records beetween two tables like this
2)how can i find differents records between, i wanna intercept the
records from "028 - prg" <> "028 - des" and replace them.

Thks in advance

Fields:danno, data, bene and impo

Use a INNER JOIN on your primary key fields and compare the non key fields.
table "028 - des"
Fields:danno, data, bene and impo

Looks like [danno] and [data] may be a candidate key, then your query
SQL may look like this:

SELECT
T1.[danno], T1.[data],
T1.[bene], T2.[bene],
T1.[impo], T2.[impo]
FROM [028 - prg] T1
INNER JOIN [028 - des] T2
ON (T1.[danno] = T2.[danno]) AND (T1.[data] = T2.[data])
WHERE (T1.[bene] <> T2.[bene]) OR (T1.[impo] <> T2.[impo])

btw, consider using table names without spaces and special characters
like '-'.
