Handle SQL warning example
In this example we shall show you how to handle SQL Warnings in Java. To handle SQL Warnings one should perform the following steps:
- Load the JDBC driver, using the
forName(String className)
API method of the Class. In this example we use the Oracle JDBC driver. - Create a Connection to the database. Invoke the
getConnection(String url, String user, String password)
API method of the DriverManager to create the connection. - Get the SQLWarning risen while connecting to the database, using the
getWarnings()
API method of the Connection. - Check the connectionWarning, with
getMessage()
,getSQLState()
,getErrorCode()
and then get the next warning withgetNextWarning()
API methods of the SQLWarning. - Execute an SQL Statement, which returns a ResultSet object. For each row of the ResultSet get the SQLWarnings, using the
getWarnings()
API method of the ResultSet. - Check on the resultsetWarning with the
getMessage()
,getSQLState()
,getErrorCode()
and then get the next warning withgetNextWarning()
API methods of the ResultSet,
as described in the code snippet below.

Output:
Successfully Connected to the database!
