Specified by:

compareSecure in class Value

Parameters:

v - the other value

mode - the compare mode

Returns:

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

getString

Returns:

the object

getBytes

public byte[] getBytes()

Overrides:

getBytes in class Value

set

public void set(java.sql.PreparedStatement prep,
                int parameterIndex)
         throws java.sql.SQLException
