Excel Spreadsheet Automation with the QUERY Formula

The CData Excel Add-In for MySQL provides formulas that can edit, save, and delete MySQL data. The following three steps show how you can automate the following task: Search MySQL 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 MySQL data records you want to retrieve or the modifications to be made, written in standard SQL.

• Connection: Either the connection name, such as MySQLConnection1, or a connection string. The connection string consists of the required properties for connecting to MySQL data, separated by semicolons.

  The Server and Port properties must be set to a MySQL server. If IntegratedSecurity is set to false, then User and Password must be set to valid user credentials. Optionally, Database can be set to connect to a specific database. If not set, tables from all databases will be returned.

• 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 MySQL data, such as ShipCountry.
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 Orders WHERE ShipCountry = '"&B6&"'","User="&B1&";Password="&B2&";Database="&B3&";Server="&B4&";Port="&B5&";Provider=MySQL",B7)
3. Change the filter to change the data.
