Dynamic parameters
You can prepare statements that are allowed to have parameters for which
the value is not specified when the statement is prepared using PreparedStatement methods
in the JDBC API. These parameters are called dynamic parameters and are represented
by a ?.
The JDBC API documents refer to dynamic parameters as IN, INOUT, or OUT
parameters. In SQL, they are always IN parameters.
New: Derby supports
the interface ParameterMetaData, new in JDBC 3.0. This interface describes
the number, type, and properties of prepared statement parameters. See the Derby Developer's Guide for more information.
You must specify values for them before executing the statement. The values
specified must match the types expected.
