Teradata

The Teradata connector allows you to connect to Teradata database servers.

IMPORTANT: To use the Teradata connector, it requires installation of Teradata client (Teradata Tools and Utilities (TTU) 8.2 or higher, which includes CLIv2, TGSS, and ICU client software, on all platforms (http://media.datadirect.com/download/docs/odbc/allodbc/index.html#page/userguide/rfi1363234536481.html#).

The tools/utilities must be installed in this sequence:

  1. ICU Client Software

  2. TGSS

  3. CLIv2

  1. Enter the name of the database to which you want to connect.

  2. The easiest way to select a table and/or view to load is by choosing from a set of predefined tables and views. To do so, ensure that the Tables & Views radio button is selected. If you wish to manually construct a SQL query to pull and load data, ensure that the Query button is selected. Once either a table or view or a query has been selected, the OK button at the bottom of the dialog is enabled.

  3. Click Load Tables to load a list of predefined tables or views. This list can be filtered by entering an appropriate string in the Search Tables search box.

You can also add a duplicate column.

  1. Select a table to display the available columns in the Search Columns list. Once a table has been selected, the Query text box is updated to reveal the results of a SELECT * FROM TABLE query. Any other selection made updates the Query text box accordingly.

  2. Select the columns to add to your data table by checking their corresponding Output Column box.

  3. If you wish to parameterize a specific column, check the Parameterize checkbox and, in the dropdowns that display, select the desired value.

  4. If the data returned is to be aggregated, check the Aggregate checkbox. The following aggregation methods are possible:

The time zone of input parameters and output data is, by default, unchanged. Changing the time zone is supported by using the Timezone list box based on the assumption that data are stored in UTC time and outputs are presented in the selected time zone.

  1. Check the box for Enable on-demand queries if you would like to enable this function.

  2. Click OK to confirm the selection and retrieve the record set into Panopticon Designer (Desktop).

The flat record set corresponding to the executed SQL is returned from the source database and displayed in Data Prep with the database name as the title and all fields listed displayed in Data Source Preview.

  1. If you wish to make changes to your fields, you may do so now and then click OK when you are finished. If you do not wish to make any changes to your data, simply select the OK button.
