Excel Spreadsheet Automation on HBase Data with the QUERY Formula

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

• Connection: Either the connection name, such as ApacheHBaseConnection1, or a connection string. The connection string consists of the required properties for connecting to HBase data, separated by semicolons.

  Set the Port and Server to connect to Apache HBase.

• 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 HBase data, such as ShipCity.
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 Customers WHERE ShipCity = '"&B3&"'","Server="&B1&";Port="&B2&";Provider=ApacheHBase",B4)
