Get the Report →Excel Spreadsheet Automation with the QUERY Formula
Pull data, automate spreadsheets, and more with the QUERY formula.
The CData Excel Add-In for Redshift provides formulas that can edit, save, and delete Redshift data. The following three steps show how you can automate the following task: Search Redshift 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 Redshift data records you want to retrieve or the modifications to be made, written in standard SQL.
Connection: Either the connection name, such as RedshiftConnection1, or a connection string. The connection string consists of the required properties for connecting to Redshift data, separated by semicolons.
To connect to Redshift, set the following:
- Server: Set this to the host name or IP address of the cluster hosting the Database you want to connect to.
- Port: Set this to the port of the cluster.
- Database: Set this to the name of the database. Or, leave this blank to use the default database of the authenticated user.
- User: Set this to the username you want to use to authenticate to the Server.
- Password: Set this to the password you want to use to authenticate to the Server.
You can obtain the Server and Port values in the AWS Management Console:
- Open the Amazon Redshift console (http://console.aws.amazon.com/redshift).
- On the Clusters page, click the name of the cluster.
- On the Configuration tab for the cluster, copy the cluster URL from the connection strings displayed.
- 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.
- 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 Redshift data, such as ShipCountry.
- 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.
- Change the filter to change the data.
=CDATAQUERY("SELECT * FROM Orders WHERE ShipCountry = '"&B6&"'","User="&B1&";Password="&B2&";Database="&B3&";Server="&B4&";Port="&B5&";Provider=Redshift",B7)
