Try using WHERE condition.

WHERE TABA.STATE EQ TABB.STATE

May be it will help

What is the source of the two tables ?

Are they from an RDBMS or FOCUS files, or Flat files ?

Sounds like flat files, with only one NY record in the second (joined-to) file.

If it's a join to a FIX file, the result is correct for a one-to-many JOIN

In a one-to-many join to a flat file, if there were several matching records in the second file they would all be coupled to the first NY record in the first file, and for subsequent NY records in the first file the cupboard would be bare (since the process does not backspace the second file).

Procedurally, Focus reads forward in the second file, after the first match, until it encounters a non-NY keyed record. It then sits on that record waiting for a record in the first file that matches it.

So any additional NY records in the first file would show no match, whether the second file contains zero, one, or several records keyed to NY.

Bottom line: Remove "ALL" from the JOIN.

If these suggestions did not help, please post both master files. That way we can certainly help you better.

TABA and TABB are not in the same sort order. They either need to both be sorted by STATE, or your TABB extract will need to have an index.

ON TABLE HOLD AS TABB FORMAT FOCUS INDEX STATE
