I have a file external to FOCUS. It is a CSV file that has only 1 column of data. I want to use this file as selection criteria - in other words I want to select all records in TABLE B (A FOCUS table) where field x equals that value in Table A which is the CSV table.

Any suggestions?

TABLE FILE CAR
SUM SALES

WHERE COUNTRY IN FILE TEST
END

There is a limit to the number of rows in a file used in a WHERE statement.

Also make sure that there is no ",{line terminator}", otherwise you will have to create a Master file to read it first.

Francis- do you know the limit? My input file may be thousands of lines long.

For a WHERE, the limit is 16000 bytes; for an IF, it is 32K bytes. This is documented in the "Creating Reports with the WebFOCUS Language".

Carl,

If your CSV fiel is "thousands of lines long", I wouldn't use the IN FILE operator. For each record of TABLE B, Focus will have to go through half your thousands of records on the average.

If, instead, you load the CSV file into a Focus file, and join TABLE B to it, the look up goes down to the base-2 logarithm of your thousands.
