I can see another question about this. However if my understanding is correct. The where clause is not working for me at any level.

I am using the blm national dataset which has a large number of records for all states. I only need to utilize 1-3 states at this time in my workbench. I have attempted a where clause on the reader

 

, an SQL before read (which seems like the most efficient) and a where clause on the table.

 

However the sql before will not run at all.

When running the where clause SECDIVID LIKE 'MN% it runs but in the test filter directly after the reader i begin getting unfiltered records. This should not be possible if it has already filtered by the where.

I am not willing to sit through all of the records (it will be at least 4 hrs) to see what happens.

does this work for anybody else?

What am i doing wrong?

I can see the following in the log. but why doesn't it only return these states. It works in Arcdesktop.

Using WHERE clause 'SECDIVID<space>LIKE<space><apos>MN%<apos><space>OR<space>SECDIVID<space>LIKE<space><apos>MI%<apos><space>OR<space>SECDIVID<space>LIKE<space><apos>WI%<apos>'

All network information will be ignored. As a result, edges will be treated as polyline features and junctions will be treated as point features

All relationship information will be ignored. As a result, simple relationships will not be read, and attributed relationships will be read as tables

If you want to check the data that the query is returning without viewing all the data you can limit the number of features to read in the reader parameter

What clause are you using in your test filter?
