java.sql.SQLException

public class java.sql

SQLException

Java SE 6

Extends: Throwable > Exception

Implements: Iterable

Extended by: BatchUpdateException, RowSetWarning, SerialException, SQLClientInfoException, SQLNonTransientException, SQLRecoverableException, SQLTransientException, SQLWarning, SyncFactoryException, SyncProviderException

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 getMesasge.
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.

Constructors

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.

reason a description of the exception

SQLState an XOPEN or SQL:2003 code identifying the exception

vendorCode a database vendor-specific exception code

public

SQLException(String reason, String SQLState)
Constructs a SQLException object with a given reason and SQLState. The cause is not initialized, and may subsequently be initialized by a call to the Throwable#initCause(java.lang.Throwable) method. The vendor code is initialized to 0.

reason a description of the exception

SQLState an XOPEN or SQL:2003 code identifying the exception

public

SQLException(String reason)
Constructs a SQLException object with a given reason. The SQLState is initialized to null and the vender code is initialized to 0. The cause is not initialized, and may subsequently be initialized by a call to the Throwable#initCause(java.lang.Throwable) method.

reason a description of the exception

public

SQLException()
Constructs a SQLException object. The reason, SQLState are initialized to null and the vendor code is initialized to 0. The cause is not initialized, and may subsequently be initialized by a call to the Throwable#initCause(java.lang.Throwable) method.

public

SQLException(Throwable cause)
Constructs a SQLException object with a given cause. The SQLState is initialized to null and the vendor code is initialized to 0. The reason is initialized to null if cause==null or to cause.toString() if cause!=null.

cause the underlying reason for this SQLException (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

since 1.6

public

SQLException(String reason, Throwable cause)
Constructs a SQLException object with a given reason and cause. The SQLState is initialized to null and the vendor code is initialized to 0.

reason a description of the exception.

cause the underlying reason for this SQLException (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

since 1.6

public

SQLException(String reason, String sqlState, Throwable cause)
Constructs a SQLException object with a given reason, SQLState and cause. The vendor code is initialized to 0.

reason a description of the exception.

sqlState an XOPEN or SQL:2003 code identifying the exception

cause the underlying reason for this SQLException (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

since 1.6

public

SQLException(String reason, String sqlState, int vendorCode, Throwable cause)
Constructs a SQLException object with a given reason, SQLState, vendorCode and cause.

reason a description of the exception

sqlState an XOPEN or SQL:2003 code identifying the exception

vendorCode a database vendor-specific exception code

cause the underlying reason for this SQLException (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

since 1.6

Methods

public Iterator

iterator()
Returns an iterator over the chained SQLExceptions. The iterator will be used to iterate over each SQLException and its underlying cause (if any).

return	an iterator over the chained SQLExceptions and causes in the proper order
since	1.6

Properties

public int

getErrorCode()
Retrieves the vendor-specific exception code for this SQLException object.

return

the vendor's error code

public void

setNextException(SQLException ex)
Adds an SQLException object to the end of the chain.

ex	the new exception that will be added to the end of the `SQLException` chain
See also	getNextException

public SQLException

getNextException()
Retrieves the exception chained to this SQLException object by setNextException(SQLException ex).

return	the next `SQLException` object in the chain; `null` if there are none
See also	setNextException

public String

getSQLState()
Retrieves the SQLState for this SQLException object.

return

the SQLState value
