Custom filter in DataConnect

As you may have realized, I am using a lot this IBM Bluemix DataConnect service. When creating an activity, you can refine the data you are going to export, using a custom filter (it enables a WHERE clause to add logic to the query)

I am trying to filter a TIMESTAMP field, trying to get 1 month old data, but the sentence is not working.

DATE(SHIPMENT_TMS) >= CURRENT DATE - 2 MONTH - (DAY(CURRENT DATE)-1)DAYS

I get the following error message

Custom Filter failed. Retry the shaping operation you just performed. •Filter rows by using the SQL WHERE clause expression 'DATE(SHIPMENT_TMS) >= CURRENT DATE - 2 MONTH - (DAY(CURRENT DATE)-1)DAYS' java.lang.RuntimeException: [1.36] failure: end of input expected DATE(SHIPMENT_TMS) >= CURRENT DATE - 2 MONTH - (DAY(CURRENT DATE)-1)DAYS

It may be that DATE() or DAY() are not recognized by the service. Did anyone attempt to do such filter?

Thanks

Data Connect does not support the above SQL. Data Connect only supports Spark SQL.

This is the general page from spark: https://spark.apache.org/docs/1.6.0/sql-programming-guide.html
