I'm an trying to build an incremental queries for a JDBC Query Consumer, where the date column is originally a varchar. So the query is like Select TO_DATE("dayofyear"), .... from XY where TO_DATE("dayofyear",'YYYYMMDD') > TO_DATE('${OFFSET}') ORDER BY TO_DATE("dayofyear",'YYYYMMDD')

OFFSET is then 2000-01-01 and offset column dayofyear. However, I get the error "Invalid column name: dayofyear". The query with a '${OFFSET}' = '2020-01-01' works fine. I can also not put TO_DATE("dayofyear",'YYYYMMDD') as offset column.

Any idea what the problem might be?

You can use your varchar field as-is for OFFSET.

The invalid column name error looks like something from the database rather than StreamSets. Check if your query runs ok directly in source.

Hm, there query runs fine directly against the database. I tried to use the varchar "as is": "Select TO_DATE("dayofyear"), .... from XY where dayofyear > TO_DATE('${OFFSET}','YYYYMMDD') ORDER BY dayofyear" I still get "Invalid column name: dayofyear"
