Choosing a JDBC driver

SQL Anywhere supports the following JDBC drivers:

• iAnywhere JDBC driver    This driver communicates with SQL Anywhere using the Command Sequence client/server protocol. Its behavior is consistent with ODBC, embedded SQL, and OLE DB applications. The iAnywhere JDBC driver is the recommended JDBC driver for connecting to SQL Anywhere databases.

• jConnect    This driver is a 100% pure Java driver. It communicates with SQL Anywhere using the TDS client/server protocol.

  jConnect and jConnect documentation are available from  http://www.sybase.com/products/informationmanagement/softwaredeveloperkit/jconnect.

When choosing which driver to use, you should consider the following factors:

• Features    The iAnywhere JDBC driver is both JDBC 2.0 and 3.0 compliant. jConnect 5.5 is JDBC 2.0 compliant and jConnect 6.0.5 is JDBC 3.0 compliant. The iAnywhere JDBC driver provides fully-scrollable cursors when connected to a SQL Anywhere database. The jConnect JDBC driver provides fully-scrollable cursors only when connected to an Adaptive Server Enterprise database.

• Pure Java    The jConnect driver is a pure Java solution. The iAnywhere JDBC driver requires the SQL Anywhere ODBC driver and is not a pure Java solution.

• Performance    The iAnywhere JDBC driver provides better performance for most purposes than the jConnect driver.

• Compatibility    The TDS protocol used by the jConnect driver is shared with Adaptive Server Enterprise. Some aspects of the driver's behavior are governed by this protocol, and are configured to be compatible with Adaptive Server Enterprise.

For information about platform availability for iAnywhere JDBC driver and jConnect, see the SQL Anywhere table in  SQL Anywhere Components by Platform.

For information about using jConnect with Windows CE, see Using jConnect on Windows CE.
