public class SQLException
extends Exception
implements Serializable, Iterable<Throwable>

An exception that indicates a failed JDBC operation. It provides the following information about problems encountered with database access:

• A message string.
• A SQLState error description string following either SQL 99 or X/OPEN SQLState conventions. DatabaseMetaData.getSQLStateType() exposes the specific convention in use.
• A database-specific error code.
• The next exception in the chain.

Method Detail

getErrorCode

public int getErrorCode()

Returns the integer error code for this SQLException.

Returns:

The integer error code for this SQLException. The meaning of the code is specific to the vendor of the database.

getNextException

public SQLException getNextException()

Retrieves the SQLException chained to this SQLException, if any.

Returns:

The SQLException chained to this SQLException. null if there is no SQLException chained to this SQLException.

getSQLState

public String getSQLState()

Retrieves the SQLState description string for this SQLException object.

Returns:

The SQLState string for this SQLException object. This is an error description string which follows either the SQL 99 conventions or the X/OPEN 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.

setNextException

public void setNextException(SQLException ex)

Obsolete. Appends ex to the end of this chain.

iterator

public Iterator<Throwable> iterator()

Obsolete. Throwable.getCause() should be used instead of this iterator. Returns an iterator over the exceptions added with setNextException(java.sql.SQLException).

Specified by:

iterator in interface Iterable<Throwable>

Returns:

An Iterator instance.
