У меня есть две таблицы мастер и детали. Я передаю XML для сохранения процедуры в качестве значения параметра, но когда мой код процедуры хранения выполняется, то никакие данные не вставляются и не выдает ошибку. я не могу понять, в чем проблема.
любой может помочь мне получить неправильную область в коде процедуры моего магазина, которая вызывает проблему.
Table code
-------------
CREATE TABLE TblTickerTemplate (
ID int identity,
Ticker varchar(20),
LineItem varchar(100),
Insertdate datetime DEFAULT GETDATE()
CONSTRAINT PK_ID PRIMARY KEY CLUSTERED (ID)
);
ALTER Table TblTickerTemplate
Add CONSTRAINT UC_Ticker_LineItem UNIQUE (Ticker, LineItem)
CREATE TABLE TblTickerTemplateDetail (
MasterTemplateID int,
ID int identity,
LineItem varchar(100),
XFundCode varchar(100),
Action Char(1),
UserID varchar(20),
Insertdate datetime DEFAULT GETDATE()
FOREIGN KEY(MasterTemplateID) REFERENCES TblTickerTemplate(ID)
);

Calling procedure this way
--------------------------
Declare @inputxml xml
Declare @Status VARCHAR(MAX)
set @inputxml='<Lineitems>
<Lineitem>
<Ticker>TER</Ticker>
<ID>0</ID>
<LineItem>Net Revenue</LineItem>
<XFundCode>TRIN</XFundCode>
<UserID>TDP</UserID>
</Lineitem>
<Lineitem>
<Ticker>TER</Ticker>
<ID>0</ID>
<LineItem>Cost of Revenue</LineItem>
<XFundCode>XXP</XFundCode>
<UserID>TDP</UserID>
</Lineitem>
</Lineitems>'
EXEC [dbo].USP_InsertUniqueLineItems @inputxml, @Status output
Select @Status
Редактировать
Я решил таким образом
/*
SAMPLE XML to insert
<Lineitems>
<Lineitem>
<Ticker>TER</Ticker>
<ID>0</ID>
<LineItem>Net Revenue</LineItem>
<XFundCode>TRIN</XFundCode>

</Lineitem>
<Lineitem>
<Ticker>TER</Ticker>
<ID>0</ID>
<LineItem>Cost of Revenue</LineItem>
<XFundCode>XXP</XFundCode>
<UserID>TDP</UserID>
</Lineitem>
</Lineitems>

но если я раскомментирую эту строку RAISERROR ('USP_InsertUniqueLineItems:', 16, 1, @ERROR, @MESSAGE), то придет ошибка. как это исправить ... поделись идеей. спасибо
