As for your previous posts and my replies on this topic- you need to start with a clear idea on how it might work, and break it into easily understandable chunks.
The INSERT INTO part of your graph is not necessary for what you have explained as this is writing to the database
The SELECT part is heading in the right direction since this is reading from the database- but the * means all columns. You need to work out which database column and which model parameter you are using to match up database records.
Without any clear idea on what you want to achieve, I'd guess you would have a query something like:
SELECT [field1] FROM [table] WHERE [field2] = [object key parameter from Revit/Dynamo]
