SQLWarning

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.

Constructors Summary
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 {@link Throwable#initCause(java.lang.Throwable)} method.

param
reason a description of the warning
param
SQLState an XOPEN or SQL:2003 code identifying the warning
param
vendorCode a database vendor-specific warning code

	super(reason, SQLState, vendorCode);
	DriverManager.println("SQLWarning: reason(" + reason + 
			      ") SQLState(" + SQLState + 
			      ") vendor code(" + vendorCode + ")");
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 {@link Throwable#initCause(java.lang.Throwable)} method. The vendor code is initialized to 0.

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

	super(reason, SQLState);
	DriverManager.println("SQLWarning: reason(" + reason + 
				  ") SQLState(" + SQLState + ")");
public SQLWarning(String reason)
Constructs a SQLWarning 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 {@link Throwable#initCause(java.lang.Throwable)} method.

param
reason a description of the warning

	super(reason);

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 {@link Throwable#initCause(java.lang.Throwable)} method. 

	super();
	DriverManager.println("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.

param
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.

        super(cause);
        DriverManager.println("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.

param

Methods Summary
public java.sql.SQLWarninggetNextWarning()
Retrieves the warning chained to this SQLWarning object by setNextWarning.

return
the next SQLException in the chain; null if none
see
#setNextWarning

	try {
	    return ((SQLWarning)getNextException());
	} catch (ClassCastException ex) {
	    // The chained value isn't a SQLWarning.
	    // This is a programming error by whoever added it to
	    // the SQLWarning chain.  We throw a Java "Error".
	    throw new Error("SQLWarning chain holds value that is not a SQLWarning");
	}
public voidsetNextWarning(java.sql.SQLWarning w)
Adds a SQLWarning object to the end of the chain.

param
w the new end of the SQLException chain

#getNextWarning

	setNextException(w);
