   Go to Structure Element.
5. Change the tHMap_1_output structure that
   opens from Read Only to Editable and then change the Data
   Type for outputkey to
   Integer (32). This means that this element
   can only be an Integer, and since this does not match the input, an
   error will occur.

   

6. In the Run tab, click Run to execute the Job again.
   In this case, the Job still triggers the second tJava component even though there is an error, because the
   threshold above which an exception should be thrown (thus enabling the
   downstream components to detect the error) is set as Fatal. However, the third tJava
   component is also triggered since there is an error in the execution of the
   map.
   

7. In the tHMap component, change the value of the Exception Threshold drop-down list (on the Advanced Settings tab) to Error. This causes an exception to be thrown when the map has a
   severity of Error or higher.
8. In the Run tab, click Run to execute the Job for a third time.
   In this case, the Job detects the error and triggers the first tJava component (OnSubjobError).

Prerequisites

This procedure provides you an example of how you import Oracle databases to Talend Studio and create input connections
to the tHMap component.

• You have a Talend Data Mapper Structure
  created from a database connection.
• You have a Talend Data Mapper Map,
  where the output element is the output of a DatabaseLookup using the database
  tables imported in Talend Data Mapper.
  See the following example:
  
• If you wish to use the attached sample project from the
  Downloads tab, you need to create databases using the
  sample database scripts in your local server.

Manually perform the migration by importing the database tables to Talend
Studio.

1. Create a new database connection in Metadata > Db Connections.
2. Select Retrieve Schema from the new DB
   Connection menu.
3. Select the table schemas to import.
   

Create a new Job that includes the tHMap component, where you can connect the
imported database tables.

1. Create a new Job.
   

2. Drag-and-drop the database tables from the Db
   Connections and select
   tOracleInput.
3. Add the following components:
   • tHMap
   • tLogRow
4. Connect the following components using the Row > Main connection:
   • tOracleInputdatabase connections to the
     tHMap
   • tHMap to the tLogRow
5. Enter xmlout when prompted for an output name.
6. Double-click tHMap to display the Structure
   Generate/Select window.
7. Select the Generate hierarchical mapper structure based on the
   schema option to automatically generate Structures.

Now that you have successfully configured tHMap, Talend Data Mapperautomatically generates a new map with
multiple records that represent the database input connections.

1. Select tHMap to show the Input Map and Output XML panes.
   See that the Input pane contains the imported database tables:
   

2. Use the AgConcat function to replace the deprecated
   DatabaseLookup function:
   1. Drag the row2 from the Input (Map) column to the
      AgConcat expression.
   2. Set SimpleLoop on the Loop
      Expression.
   3. Use the same filter values. If you have specified filter values in your
      Job using the deprecated DatabaseLookup function, re-use these filter
      values.
   

Prerequisites

• Ensure that you have created several contextual maps. In this example scenario,
  use three alternate contextual maps.
  
• In your local machine, create a text file with the following content, where
  my_map refers to the Map Variable name,
  job_with_tContextLoad refers to the Job name and
  thMap_1_c refers to the Alternate Contextual Map
  name:

  my_map;Jobs/job_with_tContextLoad/thMap_1_c

  1	my_map;Jobs/job_with_tContextLoad/thMap_1_c

  Ensure that you replace the values according to the names of the Map
  variable, the Job, and the Alternate Contextual Map you created.

Create a Job that includes tHMap, tFileInputRaw, tFileInputDelimited, tContextLoad,
and tLogRow.

1. Create a Standard Job to add the following components:
   • tFileInputRaw
   • tHMap
   • tLogRow
   • tFileInputDelimited
   • tContextLoad

   Note: tContextLoad allows the contextual variable value to change at runtime.
   This component uses a predefined schema with two columns
   (key, value), where
   key refers to the name of the contextual variable and
   value refers to the new value of the corresponding
   variable.

2. Connect the components using the Row > Main connection.
   

3. Enter out when prompted for the output name.

Before executing the Job, configure the components to add the required configuration
details.

1. Add three columns in the tRowGenerator component:
   

2. Add three columns in the out(Input) and
   tLogRow(Output) tables in the
   tLogRow component:
   

3. Specify the text file that you have previously created earlier in the
   File name/Stream field of the
   tFileInputDelimited component. See the Prerequisite for more information.
4. Enter details in the Map Variable and
   Alternate contextual Map(s) fields in the
   Advanced settings menu of
   tHMap.
   

5. Double-click tHMap to display the tHMap
   Structure Generate/Select window. For both the Input and Output
   Structures, select Generate hierarchical mapper structure based on
   the schema.
