Compare two columns form different table

  • How can i compare and find the values from two tables having column below like this.

    Table A
    Column A  Column B
    1                  1
    2                  1
    3                  1
    4                  1

    Table B
    Column A  Column B
    1                  1,2,3,4,5,6,7
    2                  2,3,4,5
    3                  3,4,5,6,7
    4                  1,5,6,7

    Compare column b in two tables and give me the results when i fined 1 from tableB.Column B. Is that possible?

  • Sorry mixed up the columns.Let me put it exactly what i am looking for.

    Table A
    Column A



    Column B
    1
    1
    1

    Table B
    Column A
    1
    2
    3
    Column B
    1,2,3,4
    2,3,4,5
    1,7,6,4

  • Can you please provide the test data in a consumable format.

    What is your comparison logic and expected output?

  • Table A
    ID Active_ID
    1 1 
    2 1
    3 1

    Table B
    ID Active Values
    1 1,2,3,4,5 
    2 2,3,4,5,6
    3 1,6,7,8,6

    SO i want to compare Active_ID with Active values and when it find Active_ID 1 value in Active Values it should return the row. So Active_ID is 1 in table A and Table be with ID 1 Active values 1,2,3,4,5 but it has matching value of 1 so it should return the row. Is it possible?

    Yes. It can be done.  But the hops that you have to jump through to do it are one of the reasons that it is advised to never store CSV values in a column.

    Now, unless you provide consumable data, with valid data types, we can only guess at a solution, which may or may not work.

    Jonathan.  I would approach this in the same way that Oleg described in his response.
