Examples of java.sql.SQLException

java.sql.SQLException
An Exception class that is used in conjunction with JDBC operations. It provides information about problems encountered with Database access and other problems related to JDBC
The SQLException class provides the following information:
- A standard Java exception message, as a String
- An SQLState string. This is an error description string which follows either the SQL 99 conventions or the XOPEN SQLstate conventions. The potential values of the SQLState string are described in each of the specifications. Which of the conventions is being used by the SQLState string can be discovered by using the getSQLStateType method of the DatabaseMetaData interface.
- An Error Code, an an integer. The error code is specific to each database vendor and is typically the error code returned by the database itself.
- A chain to a next Exception, if relevant, which can give access to additional error information.
