Manually Creating an SQL Transformation

Manually Creating an SQL Transformation

You can manually create an SQL transformation. Manually create the transformation when you configure a transformation that runs an SQL query. You might also manually create a transformation that calls a stored procedure when the procedure is not available to import. When you manually create the transformation, you configure the input and output ports and type the SQL statements in the SQL Editor.
  1. Select a project or a folder in the
    Object Explorer
    view.
  2. Click
    File
    New
    Transformation
    .
    The
    New
    dialog box appears.
  3. Select the SQL transformation.
  4. Click
    Next
    .
  5. Select
    Create as Empty
    .
  6. Enter a name for the transformation and enter the repository location for the transformation.
  7. Click
    Finish
  8. Click the
    Overview
    view to add ports to the transformation.
  9. To add an input port, click
    Input
    in the
    Ports
    panel to indicate where to add the port. Click the
    New
    button and enter the port name, the native type, and the precision.
    The default database type is Oracle. The Developer tool shows native types for Oracle databases unless you change the database type on the
    Advanced
    view.
  10. To add an output port, click
    Output
    in the
    Ports
    panel before you add the port. Click the
    New
    button and enter the port name, the native type, and the precision.
    The
    SQLError
    port is the first output port by default.
  11. In the
    Advanced
    view, select the database type that the SQL transformation connects to. Configure other advanced properties for error handling and other optional properties.
    When you choose the database type, the Developer tool changes the native datatypes of the ports on the
    Overview
    view.
  12. Type the SQL query or stored procedure call on the
    SQL
    view. Select ports for parameter binding or string substitution in the
    SQL Editor
    .
    If the stored procedure returns a result set, you must enter the stored procedure call with a syntax similar to the following syntax:
    (?Field1?,?Field2?,?Field3?) =
    call
    Stored_Procedure_Name (?Input_Parm?)
    .
