            }
        }
}

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(String reason) 
{
        super(reason);
        this.SQLState = null;
        this.vendorCode = 0;
        if (!(this instanceof SQLWarning)) {
            if (DriverManager.getLogWriter() != null) {
                printStackTrace(DriverManager.getLogWriter());
            }
        }
}

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.

Parameters:

reason - a description of the exception

 public SQLException(Throwable cause) 
{
        super(cause);
        if (!(this instanceof SQLWarning)) {
            if (DriverManager.getLogWriter() != null) {
                printStackTrace(DriverManager.getLogWriter());
            }
        }
}

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.

Parameters:

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.
