public class
SqlParameter
extends
Object
Object to represent an SQL parameter definition.
Parameters may be anonymous, in which case "name" is
null
.
However, all parameters must define an SQL type according to
Types
.
Types
Create a new SqlParameter, supplying name and SQL type.
Copy constructor.
Return whether this parameter holds input values that should be set
before execution even if they are
null
.
boolean
Return whether this parameter is an implicit return parameter used during the
results processing of
CallableStatement.getMoreResults/getUpdateCount
.
Convert a list of JDBC types, as defined in
java.sql.Types
,
to a List of SqlParameter objects as used in this package.
