Merging the dimension records in Microsoft SQL Server databases

Before you perform this task, make sure that all the dimension tables are created and have index on the PZID column.

  1. Connect to the target database.
  2. Merge the records from the source table to the dimension table. 
    MERGE INTO <TARGET_DATABASE>.<TARGET_SCHEMA>.PR_DATA_IH_DIM_<DIMENSION_NAME> T USING <SOURCE_DATABASE>.<SOURCE_SCHEMA>.PR_DATA_IH_DIM_<DIMENSION_NAME> SON (T.PZID = S.PZID) WHEN NOT MATCHED THEN INSERT (column1 [, column2 ...]) VALUES (S.column1 [, S.column2 ...]);
What to do next: If you want to merge the dimension records from the source database to the target database, repeat this procedure for all the dimension tables.
