public class SQLException
extends Exception
implements Iterable<Throwable>

An exception that provides information on a database access error or other errors.

Each SQLException provides several kinds of information:

• a string describing the error. This is used as the Java Exception message, available via the method getMessage.
• a "SQLstate" string, which follows either the XOPEN SQLstate conventions or the SQL:2003 conventions. The values of the SQLState string are described in the appropriate spec. The DatabaseMetaData method getSQLStateType can be used to discover whether the driver returns the XOPEN type or the SQL:2003 type.
• an integer error code that is specific to each vendor. Normally this will be the actual error code returned by the underlying database.
• a chain to a next Exception. This can be used to provide additional error information.
• the causal relationship, if any for this SQLException.

SQLException

public SQLException(String reason,
 String SQLState,
 int vendorCode)

Constructs a SQLException object with a given reason, SQLState and vendorCode. The cause is not initialized, and may subsequently be initialized by a call to the Throwable.initCause(java.lang.Throwable) method.

Parameters:

reason - a description of the exception

SQLState - an XOPEN or SQL:2003 code identifying the exception

vendorCode - a database vendor-specific exception code

SQLException
