Retrieves the value of the designated column in the current row of this ResultSet object and will convert from the SQL type of the column to the requested Java data type, if the conversion is supported. If the conversion is not supported or null is specified for the type, a SQLException is thrown.

At a minimum, an implementation must support the conversions defined in Appendix B, Table B-3 and conversion of appropriate user defined SQL types to a Java type which implements SQLData, or Struct. Additional conversions may be supported and are vendor defined.

Parameters:

columnIndex		the first column is 1, the second is 2, ...
type		Class representing the Java data type to convert the designated column to.

Returns:  an instance of type holding the column value

Exceptions:

SQLException		if conversion is not supported, type is null or another error occurs. The getCause() method of the exception may provide a more detailed exception, for example, if a conversion error occurs
SQLFeatureNotSupportedException		if the JDBC driver does not support this method
