bind

public int bind(PreparedStatement statement,
                QueryParameters qp,
                SharedSessionContractImplementor session,
                int position)
         throws SQLException

Bind the appropriate value into the given statement at the specified position.

参数:

statement - The statement into which the value should be bound.

qp - The defined values for the current query execution.

session - The session against which the current execution is occurring.

position - The position from which to start binding value(s).

返回:

The number of sql bind positions "eaten" by this bind operation.

抛出:

SQLException - Indicates problems performing the JDBC bind operation.

renderDisplayInfo

public String renderDisplayInfo()

从接口复制的说明: ParameterSpecification
