Excel Spreadsheet Automation on MarkLogic Data with the QUERY Formula

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

• Connection: Either the connection name, such as MarkLogicConnection1, or a connection string. The connection string consists of the required properties for connecting to MarkLogic data, separated by semicolons.

  Set User, Password, and Server to the credentials for the MarkLogic account and the address of the server you want to connect to. You should also specify the REST API Port if you want to use a specific instance of a REST Server.

• 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 MarkLogic data, such as Id.
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 Customer WHERE Id = '"&B4&"'","User="&B1&";Password="&B2&";Server="&B3&";Provider=MarkLogic",B5)
