    With this option, you change the data source and the sampling settings:

    • Data Source: keep the original source or click Edit () icon and choose a new data source.
      Note: Only a data source with the same connection as the original data source can be selected.

      • The Load all rows option is default selection.
      • Select Load sample rows to specify if you want to sample first set of rows or random rows.
    • (Optional) SQL Where Clause: if you are loading data from a relational data source (DB2, Oracle, or ODBC-compliant database), you have the option to selectively retrieve data by defining an SQL Where clause. For information, see Filtering Relational Database Data.
    • Schedule Job: select Now to run or select Later to pick a data to schedule the job.

    Loads the data into the repository with original settings specified when the data source was created.

  5. Click Load to start the job.
  6. When the job completes, open a List View of the new data source and verify the data loaded correctly.
  7. If expected attributes do not display, open the Choose Columns window (right-click a column title and select Choose Columns) and move any hidden columns into the Displayed fields list.

Filtering Relational Database Data

If you are creating a data source from a relational data source, you have the option to selectively retrieve data by defining a SQL where clause. For example, you might want to exclude data for a particular sales rep or region.

Note: This procedure assumes you are familiar with the syntax for defining structured query language (SQL) conditions. If you are not, refer to a SQL Reference Guide.
Note: does not validate your SQL clauses.
Note: Extended SQL syntax is not valid.

To filter relational database data

  1. When you create the data source, click the Add SQL WHERE clause checkbox in the Create Data Source Wizard window, then click Next. The SQL Where Clause Entry window opens.
  2. (Optional) Click the Preview button to display a List View of the table you are using to create this data source. Note the exact names of the attributes you will be using to filter your data.
  3. In the text box, type the SQL where clause. For example, type Country < > 'CAN' to exclude data rows in which the country is Canada.
    Note: You do not need to type the word WHERE as part of the syntax.
  4. (Optional) Click Preview to review the results of the filter.
  5. Click Next.
