Data lost when joining table

[#1]

Hi all,

I am trying to join 2 data tables but the data from my second data table kept on losing. I don't know how to do this, but I am using three columns to match. Is joining the table affected on how you match the data? Pls help

If you can supply some example data we would be better able to assist you.

Here's my sample data and sample script

Data Table( "sample2" ) << Join(
    With( Data Table( "sample1" ) ),
    By Matching Columns( :SliderSN = :SliderSN, :STO_I1 = :STO_I1, :STO_I2 = :STO_I2 ),
    Drop multiples( 0, 0 ),
    Include Nonmatches( 1, 0 ),
    Preserve main table order( 1 )
)

What sort of table do you want to end up with? The data from second table could have lost because there is nothing to match the table 1 with and you are using left join.

Try playing around with different types of include-non-matches options with enable match flag enabled. Also you can enable Keep Dialog Open to prevent modal from closing after pressing Apply. Makes it easier to test different options. 

You could also try concatenating the data because you have same columns
