| Method Summary | |
| void | checkRange(int param)
Checks if the value of the param argument is a valid parameter
position. | | public String | getParameterClassName(int param)
Retrieves the fully-qualified name of the Java class whose instances
should be passed to the method PreparedStatement.setObject. | | public int | getParameterCount()
Retrieves the number of parameters in the PreparedStatement object for
which this ParameterMetaData object provides information. | | public int | getParameterMode(int param)
Retrieves the designated parameter's mode. | | public int | getParameterType(int param)
Retrieves the designated parameter's SQL type. | | public String | getParameterTypeName(int param)
Retrieves the designated parameter's database-specific type name. | | public int | getPrecision(int param)
Retrieves the designated parameter's number of decimal digits. | | public int | getScale(int param)
Retrieves the designated parameter's number of digits to right of
the decimal point. | | public int | isNullable(int param)
Retrieves whether null values are allowed in the designated parameter. | | public boolean | isSigned(int param)
Retrieves whether values for the designated parameter can be
signed numbers. | | public String | toString()
Retrieves a String repsentation of this object. |
| classNames | | String[] classNames(Code) | | The fully-qualified name of the Java class whose instances should
be passed to the method PreparedStatement.setObject.
Note that changes to Function.java and Types.java allow passing
objects of any class implementing java.io.Serializable and that,
as such, the parameter expression resolution mechanism has been
upgraded to provide the precise FQN for SQL function and stored
procedure arguments, rather than the more generic
org.hsqldb.JavaObject class that is used internally to represent
and transport objects whose class is not in the standard mapping.

| jdbcParameterMetaData | | jdbcParameterMetaData(Result r) throws SQLException(Code) | | Creates a new instance of jdbcParameterMetaData.
Parameters:
r - A Result object describing the statement parameters
throws:
SQLException - never - reserved for future use |
| checkRange | | void checkRange(int param) throws SQLException(Code) | | Checks if the value of the param argument is a valid parameter
position.
Parameters:
param - position to check
