Exclude values stored in data table from SQL query

Posted on by schill27

I have a flow that first reads a CSV file and stores the values in a data table variable. Next, the flow opens a SQL connection and executes a SQL statement. What I'm trying to accomplish is excluding the data table's values from the SQL query results. For sake of example only (I know the syntax is wrong), I want whatever the equivalent is to: "SELECT * FROM members WHERE member_id not in (SELECT member_id from %CSVDataTable%)". In this example, %CSVDataTable% is the variable that was created when reading the CSV file and the rest of SQL statement is what I would execute against the SQL connection. Thoughts?

Thanks!

Hi

Can you give more details about what the Field/Fields are you need to match to make sure they don't exist?

You have a couple of options.

1. Depending on the field type you can use in, and depending on whether thats an in (and you have a gallery of ints to compare against), or a string where you have to concat the entire string together to check if its in

2. You could query the data into another gallery and then union them together to take out all the duplicates

Other options are possible but need to understand the uniqe thing, I wasn't sure if member_id is it and is member_id an INT or a STR?

The value from the SQL query would be an INT. I'm unsure what the data type is when PAD reads from a CSV. It's very possible these two data types are different from one another.
