Class SQLWarning

All Implemented Interfaces:
Serializable, Iterable<Throwable>
Direct Known Subclasses:
DataTruncation
public class SQLWarning
extends SQLException

An exception that provides information on database access warnings. Warnings are silently chained to the object whose method caused it to be reported.

Warnings may be retrieved from Connection, Statement, and ResultSet objects. Trying to retrieve a warning on a connection after it has been closed will cause an exception to be thrown. Similarly, trying to retrieve a warning on a statement after it has been closed or on a result set after it has been closed will cause an exception to be thrown. Note that closing a statement also closes a result set that it might have produced.

Since:
1.1

SQLWarning

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

Constructs a SQLWarning 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 warning
SQLState - an XOPEN or SQL:2003 code identifying the warning
vendorCode - a database vendor-specific warning code

SQLWarning

public SQLWarning(String reason,
                  String SQLState)

Constructs a SQLWarning 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.

Parameters:
reason - a description of the warning
SQLState - an XOPEN or SQL:2003 code identifying the warning

SQLWarning

public SQLWarning(String reason)

Constructs a SQLWarning object with a given reason. The SQLState is 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.

Parameters:
reason - a description of the warning

SQLWarning

public SQLWarning()

Constructs a SQLWarning 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.

SQLWarning

public SQLWarning(Throwable cause)

Constructs a SQLWarning 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.

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

SQLWarning

public SQLWarning(String reason,
                  Throwable cause)

Constructs a SQLWarning object with a given reason and cause. The SQLState is initialized to null and the vendor code is initialized to 0.

Parameters:
reason - a description of the warning
cause - the underlying reason for this SQLWarning (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

Parameters:
reason - a description of the warning
SQLState - an XOPEN or SQL:2003 code identifying the warning
cause - the underlying reason for this SQLWarning (which is saved for later retrieval by the getCause() method); may be null indicating the cause is non-existent or unknown.

SQLWarning

public SQLWarning(String reason,
