I am currently using the JDBC Producer stage to insert new records in my mysql databases. This works fine without issues. I now need to UPDATE some of the records with something like:

UPDATE db.table SET login_date=${(record:value("/myfield")}  WHERE prikey=${(record:value("/key")}

But there doesn't seem to be any input box where i can put in a query like the one above.

Also, I looked at the JDBC lookup stage but it seems that it is only for querying, not writing.

What stages do I need in order to DB updates like this?

thank you.

See the documentation on setting the CRUD operation in the record. You need to set the sdc.operation.type to 1 for INSERT or 3 for UPDATE, and ensure that the record field corresponding to the table's primary key is set; the JDBC Producer destination will automatically generate an update statement of the form you described.

Hi Pat, Thanks for this. I might have missed that section of the link where it says there is an implicit "WHERE" clause in the stage. The example given in that section was quite useful.
