Lost data in Union Query

D

DZ

The total number of records in 3 tables used in a union query is about
40,000. The Union Query is omly displaying about 13, 000.

there are no filters. The data types match up.

CAn anyne tell me why there is missing data in the Union Query?

Here is the SQL

SELECT [Data Provider], [Hospital_Name], [Insured Name], [Policy Year],
[TOTAL IND RES], [TOTAL IND PAID], [TOTAL ALAE RES], [TOTAL ALAE PAID],
[REG RES], [REG PAID], [MLMIC xs ALAE RES], [MLMIC xs ALAE PAID], [MLMIC

Thank you for any help

PS

The fields named RR1, RR2 etc were generated because there were no
cooresponding fields in the underlying tables so I added those Null as RR1 so
the query would open. The Query referred to in the SQL select statement has
no records but has correct field names for the client.

UNION combines duplicate rows into one row

UNION ALL does not combine the duplicate rows. So try replacing UNION with
UNION ALL
