调用存储过程

功能概述

在报表中使用内嵌数据集时支持调用存储过程,只需在查询语句中输入存储过程的名称即可实现调用。

如果存储过程中定义了参数,那么调用该存储过程时也必须带参数调用。

下面分别为您介绍如何调用不带参数和带参数的存储过程(SQL Server数据库)。

调用不带参数的存储过程

例如,数据库中已经定义了一个不带参数的存储过程,名为“ myTestproc ”。

那么我们在调用它时,直接在查询语句中输入存储过程的名称即可。如下图所示。

调用带参数的存储过程

如果存储过程中定义了参数,那么在调用该存储过程时也必须添加参数。

例如存储过程名为“ CustOrdersDetail ”,并且带有一个整型的参数。

那么我们调用该存储过程时,首先需要在报表中创建一个整型的报表参数。

然后再创建内嵌数据集,使用参数调用存储过程。

提示

查询语句中使用的参数名与存储过程中定义的原参数名可以不一致。

如需调用带有多个参数的存储过程,查询语句中的参数名之间应使用英文逗号分隔。
