How to update EnterpriseDB from Excel

The CData Excel Add-In for EnterpriseDB enables you to edit and save EnterpriseDB data directly from Excel. This article explains how to transfer data from Excel to EnterpriseDB. This technique is useful if you want to work on EnterpriseDB data in Excel and update changes, or if you have a whole spreadsheet you want to import into EnterpriseDB. 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 EnterpriseDB connection by clicking From EnterpriseDB on the ribbon.

The following connection properties are required in order to connect to data.

• Server: The host name or IP of the server hosting the EnterpriseDB database.
• Port: The port of the server hosting the EnterpriseDB database.

You can also optionally set the following:

• Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

Connect Using Standard Authentication

To authenticate using standard authentication, set the following:

• User: The user which will be used to authenticate with the EnterpriseDB server.
• Password: The password which will be used to authenticate with the EnterpriseDB server.

Connect Using SSL Authentication

You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

• SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
• SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
• SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
• SSLClientCertType: The certificate type of the client store.
• SSLServerCert: The certificate to be accepted from the server.

Retrieve Data from EnterpriseDB

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

1. Click the From EnterpriseDB 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 EnterpriseDB

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 EnterpriseDB, 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.
