Hi Max,
There was another topic about saving a NULL value to the database, but that was not the same as my case.
I'm trying to write the value NULL to the database by using "Modify data source" in the "Save data" operator. This results in a INSERT or UPDATE query, depending on if there is a WHERE clause or not.
However, in the query the NULL value is added as a string "NULL", causing SQL errors and of course not writing the correct data to the database.
What can I do to solve this?
Best regards,
Bart
Hi Bart
Do not include the field in the list of fields in "Modify data source", if the table column has NULL as the default value then it will get NULL
Hi Max,
Sure, I can do it that way in case of "INSERT" statement. But not if it is an "UPDATE" statement.
In this example I overwrite values only for a specific set of data.
Then you can use {const:null} instead of NULL in the "Modify Data Source"
