Excel Spreadsheet Automation with the QUERY Formula

Pull data, automate spreadsheets, and more with the QUERY formula.

The CData Excel Add-In for Impala provides formulas that can edit, save, and delete Impala data. The following three steps show how you can automate the following task: Search Impala 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 Impala data records you want to retrieve or the modifications to be made, written in standard SQL.
  • Connection: Either the connection name, such as ApacheImpalaConnection1, or a connection string. The connection string consists of the required properties for connecting to Impala data, separated by semicolons.

    In order to connect to Apache Impala, set the Server, Port, and ProtocolVersion. You may optionally specify a default Database. To connect using alternative methods, such as NOSASL, LDAP, or Kerberos, refer to the online Help documentation.

  • 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 Impala data, such as Country.
  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.
  3. =CDATAQUERY("SELECT * FROM Customers WHERE Country = '"&B3&"'","Server="&B1&";Port="&B2&";Provider=ApacheImpala",B4)
  4. Change the filter to change the data.
