I need some help with SQL.

I have 2 Tables TABA & TABB which have a common field, say FLD1

TABA is unique on FLD1. TABB has millions of records for one value of FLD1.
TABB is a partitioned file with billions of records.

TABB also has FLD2 for Status and FLD3 for date (field type is decimal).

I want to select all records in TABA where there is at least one record in
TABB with matching FLD1 and FLD2 = 'P' and FLD3 > 20190101

Can anyone please suggest sql. It is a one-time exercise.
Also, if anyone is familiar with 'SEQUEL' by HelpSystems, we are required
to use that on prod boxes, and there are subtle differences in the syntax.

TIA for the help
