Map parameters from the selected stored procedure to the corresponding columns in the data table 將參數(shù)從選中的存儲過程映射到數(shù)據(jù)表中相應(yīng)的列。
By mapping parameters to columns in a dataset table , so that the values can be extracted from data rows when needed 通過將參數(shù)映射到數(shù)據(jù)集表中的列,以便可以在需要時從數(shù)據(jù)行提取值。
Fortunately , for web service clients , the proxy class handles the work of mapping parameters to xml elements and then sending the soap message over the network 幸好對于web服務(wù)客戶端來說,代理類處理將參數(shù)映射為xml元素,然后通過網(wǎng)絡(luò)發(fā)送soap消息這些工作。
If you use user - defined variables , make sure that you set the data type to a type that is compatible with the data type of the column that the mapped parameter references 如果使用用戶定義變量,請確保將數(shù)據(jù)類型設(shè)置為與使用該變量的參數(shù)所映射到的列的數(shù)據(jù)類型相兼容的類型。
If the parameter names are returned from the rdbms , you can use parameter names to map parameters in a parameter list to parameters in an sql statement ; otherwise , the parameters are mapped to the parameter in the sql statement by their ordinal position in the parameter list 如果參數(shù)名是從rdbms返回的,則可以使用參數(shù)名來將參數(shù)列表中的參數(shù)映射到sql語句中的參數(shù);否則,參數(shù)將按它們在參數(shù)列表中的序數(shù)位置映射到sql語句中的參數(shù)。
