Excel Spreadsheet Automation on Teradata Data with the QUERY Formula

The CData Excel Add-In for Teradata provides formulas that can edit, save, and delete Teradata data. The following three steps show how you can automate the following task: Search Teradata data for a user-specified value and then organize the results into an Excel spreadsheet.

The syntax of the CDATAQUERY formula is the following:

=CDATAQUERY(Query, [Connection], [Parameters], [ResultLocation]);

This formula requires three inputs:

• Query: The declaration of the Teradata data records you want to retrieve or the modifications to be made, written in standard SQL.

• Connection: Either the connection name, such as TeradataConnection1, or a connection string. The connection string consists of the required properties for connecting to Teradata data, separated by semicolons.

  To connect to Teradata, provide authentication information and specify the database server name.

  • User: Set this to the username of a Teradata user.
  • Password: Set this to the password of the Teradata user.
  • DataSource: Specify the Teradata server name, DBC Name, or TDPID.
  • Port: Specify the port the server is running on.
  • Database: Specify the database name. If not specified, the default database is used.
• ResultLocation: The cell that the output of results should start from.

Pass Spreadsheet Cells as Inputs to the Query

The procedure below results in a spreadsheet that organizes all the formula inputs in the first column.

1. Define cells for the formula inputs. In addition to the connection inputs, add another input to define a criterion for a filter to be used to search Teradata data, such as CategoryId.
2. In another cell, write the formula, referencing the cell values from the user input cells defined above. Single quotes are used to enclose values such as addresses that may contain spaces.

=CDATAQUERY("SELECT * FROM NorthwindProducts WHERE CategoryId = '"&B5&"'","User="&B1&";Password="&B2&";Server="&B3&";Database="&B4&";Provider=Teradata",B6)
