  1. Click Tables.
  2. Click the name of the table you want to validate.
  3. Click the Validation tab.
  4. Click next to Stand Alone Validation.
  5. [Optional] Enter the Validation Frequency. Use the calendar to enter when to start and repeat the validation. For example, you can assign the validation to occur the first day of every month at 12 am.
  6. [Optional] Enter the Where clause. These are the parameters for partial table validation. For example, to include only rows that are more than or equal to 100 in column_01, the format is: column_01>=100
  7. Select one or both of the table validation techniques:
    Validation Technique Description
    Row Count flag Select the Row count flag box to verify whether the row count of a table matches across the Teradata Database.
    Validation Expression Enter a Validation Expression, up to 500 characters, for a custom table validation with a set of rows in a table.
    For table validation on Hadoop or Aster systems, the validation expression technique is not available. The field Hadoop rowcount column is applicable for table validation involving a Hadoop system.
  8. [Optional] If you check the Row count flag, choose how to define validation failure.
    • Use base tables rules. Base table rules are global rules defined in the Manage Synchronization Rules view.
    • Use a custom rule to enter the limit for the row count difference across systems. You can enter a whole number or a percent value with decimals. For example, 1,200, 10% or 5.23% are acceptable.
  9. Set up an alert if validation fails.
  10. [Optional] Override default system selections and credentials. This allows you to enter a different database user.
  11. Click Test to verify the validation. Test is not available for table validation involving Hadoop or Aster systems.
  12. Click Apply for the changes to take effect.
