SSIS Look up

  • Hi,

    I have two tables.

    TABLE A : 1 Column AID : values 1 2 3

    TABLE B : 1 Column BID : values 3 4 5

    If I consider A as source table and look up on table B

    Then Matched o/p = 3 and UnMatched o/p = 1, 2

    I want something like it should populate 4, 5 from the lookup (Rows from Lookup not matched by the source).

    I know I can acheive this by just reversing the scenario (Table B as source and Lookup table A)

    But for 1 crore records it becomes much slow(hectic)

    In sql 2008 we have MERGE statement, in this we have if matched, if not matched and if not matched by the source. (some thing like this in lookup).

    If the above is not possible suggest a suitable method to acheive the desired purpose.

  • You have given your suggested input data, but the desired output is unclear to me.

    Are you saying that you want table A to contain all of the values in table B after the package has run?

    TABLE A : 1 Column AID : values 1 2 3 4 5

    ?

  • I donot want table A to contain all of the values in table B after the package has run.

    If I consider A as source table and look up on table B

    Then Matched o/p = 3 and UnMatched o/p = 1, 2

    I want 4, 5 as output..

  • You have merely repeated your first question. Saying that you want something 'as output' does not mean anything to me. Are you trying to populate a lookup table with missing values before doing the lookup?

    If you haven't even tried to resolve your issue, please don't expect the hard-working volunteers here to waste their time providing links to answers which you could easily have found yourself.

  • The way you want it, TableB is the source and TableA is the lookup table. Period.

    You can try to implement it with TSQL using WHEN NOT EXISTS to speed up performance.

  • Yes you can use table2 has source table 1 is look up table. so that you can get the out put of 4,5 in the non matching output.
