SQL has no idea what upload is,
You might be able to do
dt = Data Table( "ServerData" ) << Join(
With( Data Table( "DataProcessed" ) ),
Merge Same Name Columns,
Copy second table formula( 0 ),
Suppress main table formula evaluation( 0 ),
By Matching Columns( :Individual_Claim_Number_ID_Full = :Individual_Claim_Number_ID_Full ),
Drop multiples( 0, 0 ),
Name( "Include non-matches" )(0, 1),
Preserve main table order( 1 ),
Output Table( "Upload" )
);
dt << Save DataBase("Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MAWA_REP;Data Source=USFLI-WAS101", "dbo.all_customers");
But I'm pretty sure that would actually overwrite your sql table.
You could write the sql dymanically. Just for through your table to put in all the values into a SQL string that you can then run.
INSERT INTO [dbo].[ALL_CUSTOMERS]
(col1, col2)
VALUES
(col1_value1, col2_value1),
(col1_value2, col2_value2),
