Specifies the name of the server where the database is installed.

Note: You may need to append the SQL Azure server name to the login in the connection string using the <login>@<server> notation. If you do, separate the login and the SQL Azure server name with the at (@) symbol. For more information, see Connecting to SQL Azure.

Database

Specifies the name of the database that you want to connect to.

Use Encrypted Connection

Indicates that the SQL Server connection that is being established is encrypted to guarantee privacy.

ODBC Data Source

Specifies the data source to which you want to connect. The drop-down list displays the data sources that are defined on your computer.

Specifies the relational database that stores the metadata for Hive tables and partitions in a relational database. This parameter is specific to Hive.

Note: Ensure that you install the drivers that correspond to the Metastore Database that you select.

ODBC Data Source

Specifies the data source to which you want to connect. The drop-down list displays the data sources that are defined on your computer.

Invoke ODBC Administrator

Specifies whether you want to start the ODBC Administrator software and display the Select Data Source dialog. You can then select a previously defined data source, or create a data source.

Note: For FE or Alter Script process, on the Hive Connection dialog, always set the Metastore Database to Default and the ODBC Data Source to relevant Hive connection driver.

Alternate Catalog

Specifies the name of the alternate catalog that you want to use for the connection. If you leave this value empty, the application connects to the system catalog. If necessary, consider connecting to the alternate catalog for faster reverse engineering.
