Informatica filter based on the date column on the other table in the different database?

Question

In Informatica 10.2, I have requirement to filter the data on the main table based on the other table value which is in the different database.

Scenario:

Table1 (Db1 )

  Column in the tables: Name, Age, salary, last_updated

Table2 (Db2)

  Column in the tables: Tablename, last_pull_time, NoofRecords

Assume Table2 always return one row (based on the where clause it always return 1 row for the specified table name)

Now in the target, I need to load the data of Table1 but I need to filter the data based on the last_pull_time (Table)

Condition:

  Table1.last_updated > Table2.last_pull_time

How to achieve this filter since both the tables are in different database?

Note: I'm new to Informatica

Answer 1

You can achieve it thriugh below process,

1. Get Table1 as source in the Mapping

2. Import Table2 as unconnected lookup. Use table_name as join condition.

3. In expression transformation, pass table_name as argument and return the value of lookup which is last_pull_time

4. Use filter transformation to filter the records Table1.last_updated > lookup's result

5. Pass it to the target

   Source --> Expression --> Filter --> Target <br> ^ | Lookup
