Question

如果使用独立的存储过程ins_address，则没有错误。使用VB代码（如下所示）时，行不会插入到tbl_AddressEntity中。 tbl_Address确实如此，没关系。我绞尽脑汁将近两天，我准备跳下悬崖。谁能告诉为什么这行不会插入第二张表？谢谢。

数据适配器更新程序： `

Public Sub updateAddresses(ByRef dsTemp As dsAddress)

            'For inserts we're passing back the new PKID amd syncing with the dataset via the source column mapping on the insert command. 
            'So we should be able to update by ref.
            Me.SqlDaAddress.Update(dsTemp)

DsAddress1数据集包含一个表，其中包含相关存储过程中此select语句的结果： `

为什么选择这条线？

RETURN SCOPE_IDENTITY();

此时退出存储过程而不执行剩余代码。

MSDN说

Exits unconditionally from a query or procedure. RETURN is immediate and complete 
and can be used at any point to exit from a procedure, batch, or statement block. 
Statements that follow RETURN are not executed.

...请不要跳......： - ）

VB.net使用存储过程插入到多个相关表中。只有第一个表接收插入的行
