Creating CA-Datacom tables and views for Classic federation

To query or update data in a CA-Datacom database, you must create a relational table that maps to that database. You can also create a view on the table to filter record types or to filter rows and columns.

About this task

One or more FIELD entities are associated with a table in a CA-Datacom database. These FIELD definitions describe the contents of the table. In the CA-Datacom documentation, FIELD entities are also referred to as columns when the SQL option is used to access the CA-Datacom table. The online help does not use the term column to refer to a CA-Datacom FIELD entity.

The table that you map to must have one or more CA-Datacom ELEMENT definitions associated with it. A CA-Datacom ELEMENT definition refers to one or more contiguous CA-Datacom FIELD entities and is the unit of data transfer between Classic federation and a CA-Datacom database.

Use the New CA-Datacom Table wizard to create the table and optionally the view. For more information about creating tables and views that map to CA-Datacom databases, see the related links for CA-Datacom syntax diagrams and for views.

Procedure

To create a CA-Datacom table and optionally a view for Classic federation:

  1. Map your CA-Datacom database to a relational table and optionally a view by using the New CA-Datacom Table wizard.
    1. Open the wizard by right-clicking either the database in your data design project or one of the schemas within the database. Select Add Classic Object > CA-Datacom table.
    2. Select the copybook or include file that you want to base the table on.
    3. Choose whether to use the table for queries, updates, or both.
    4. Choose whether to create a view on the table.
    5. Provide information about which record entity you want to map to and the URT for accessing the corresponding CA-Datacom table.
    6. Select the fields that you want to map to columns in your relational table.
    7. If you are creating a view, specify the criteria for the WHERE clause.
    When you finish the wizard, the new table appears under the selected schema. If you created a view, the view also appears under the selected schema.
  2. Optional: Modify the table properties or add privileges. Select the table and make any changes in the Properties view.
  3. Optional: Create one or more indexes on the table. See Creating indexes.
  4. Optional: Generate the DDL for the table. You can generate the DDL later, if you do not want to generate it now. You can also generate the DDL for all of the objects within the same schema. See Generating DDL.
    1. Right-click the table and select Generate DDL.
    2. In the Generate DDL wizard, follow these steps:
      1. Choose to generate CREATE statements.
      2. Choose to generate DDL for tables. You can also choose to generate DDL for indexes.
      3. Name the file in which to save the DDL within your project.
      4. Choose whether to run the DDL on a data server. After you run the DDL, check the Data Output view to determine if the DDL ran successfully.
      5. Choose whether to open the DDL for editing.
  5. Optional: If you ran the DDL successfully on a data server, validate the table by running a test query against your CA-Datacom database. Be sure that the data server is connected to that database.
    1. In the Database Explorer, search your data server for the schema that you created the table in. Expand the schema and expand the Tables folder.
    2. Right-click the table and select Data > Sample Contents.
    3. Check the Data Output view to determine whether the test query ran successfully.
  6. Optional: If you created a view, you can generate the DDL for the view now or later. You can also generate the DDL for all of the objects within the same schema. See Generating DDL.
    1. Right-click the view and select Generate DDL.
    2. In the Generate DDL wizard, follow these steps:
      1. Choose to generate CREATE and ALTER statements.
      2. Choose to generate DDL for views.
      3. Name the file in which to save the DDL within your project.
      4. Choose whether to run the DDL on a data server. After you run the DDL, check the Data Output view to determine if the DDL ran successfully.
      5. Choose whether to open the DDL for editing.
  7. Optional: If you ran the DDL successfully on a data server, you can validate the view by running a test query against your CA-Datacom database. Be sure that the data server is connected to that database.
    1. In the Database Explorer, search your data server for the schema that you created the view in. Expand the schema and expand the Views folder.
    2. Right-click the view and select Data > Sample Contents.
    3. Check the Data Output view to determine whether the test query ran successfully.
