How to update MariaDB from Excel

The CData Excel Add-In for MariaDB enables you to edit and save MariaDB data directly from Excel. This article explains how to transfer data from Excel to MariaDB. This technique is useful if you want to work on MariaDB data in Excel and update changes, or if you have a whole spreadsheet you want to import into MariaDB. In this example, you will use the Orders table; however, the same process will work for any table that can be retrieved by the CData Excel Add-In.

Establish a Connection

If you have not already done so, create a new MariaDB connection by clicking From MariaDB on the ribbon.

The Server and Port properties must be set to a MariaDB 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, the tables from all databases are reported.

Retrieve Data from MariaDB

To insert data into MariaDB, you will first need to retrieve data from the MariaDB table you want to add to. This links the Excel spreadsheet to the MariaDB table selected: After you retrieve data, any changes you make to the data are highlighted in red.

1. Click the From MariaDB button on the CData ribbon. The Data Selection wizard is displayed.
2. In the Table or View menu, select the Orders table.
3. In the Maximum Rows menu, select the number of rows you want to retrieve. If you want to insert rows, you need to retrieve only one row. The Query box will then display the SQL query that corresponds to your request.
4. In the Sheet Name box, enter the name for the sheet that will be populated. By default the add-in will create a new sheet with the name of the table.

Insert Rows to MariaDB

After retrieving data, you can add data from an existing spreadsheet in Excel.

1. In a cell after the last row, enter a formula referencing the corresponding cell from the other spreadsheet; for example, =MyOrdersSheetInExcel!A1.
2. After using a formula to reference the cells you want to add to MariaDB, select the cells that you are inserting data into and drag the formula down as far as needed. The referenced values you want to add will be displayed on the Orders sheet.
3. Highlight the rows you want to insert and click the Update Rows button.

As each row is inserted, the Id value will appear in the Id column and the row's text will change to black, indicating that the record has been inserted.
