Filter to retrieve a single row Type in a Filter which will allow Oracle Data Integrator to locate a specific row in the table when the sequence table contains more than one row. This filter picks up the SQL syntax of the data server. For example: CODE_TAB = 3 You can use the Expression Editor to edit the filter. Click Testing query on the DBMS to check the syntax of your expression. Note: When Oracle Data Integrator wants to access the specific sequence value, the query executed on the schema will be SELECT column FROM table WHERE filter.
