我已使用存储过程和游标循环在主表中添加数据,这是我正在将csv文件中的数据添加到临时表中以及从临时表中添加数据到主表中
alter PROCEDURE [dbo].[CreateHub]
@HubName varchar(100)
AS
INSERT INTO dbo.HUB1
(HUB_NAME)
SELECT @HubName
WHERE (NOT EXISTS
(SELECT ID_HUB, HUB_NAME
FROM dbo.HUB1
WHERE (HUB1.hub_name = @HubName)))
SELECT ID_HUB AS newHubId
FROM dbo.HUB1
WHERE (hub1.hub_name = @HubName)
GO
完成此操作后,还有另一个代码正在从csv文件进行批量插入并运行游标循环以在主表中添加数据
bulk insert [dbo].[HUB_temp]
from 'C:\POPAD-DAT\HUB1.csv'
with (fieldterminator = ',', rowterminator = '\n')
go
DECLARE @sSQL AS nVARCHAR(100)
DECLARE @ItemsFromCSV AS nvarchar(200)
DECLARE sql_cursor_hub CURSOR
FOR SELECT HUB_NAME FROM HUB_temp
OPEN sql_cursor_hub
FETCH NEXT FROM sql_cursor_hub
INTO @ItemsFromCSV -- Multiple variables for multiple CSV columns will be required
WHILE @@FETCH_STATUS = 0
BEGIN
set @sSQL = 'EXEC [dbo].[CreateHub] ' + @ItemsFromCSV -- AND OTHER Parameters
print @sSQl
EXECUTE sp_executesql @sSQL
FETCH NEXT FROM sql_cursor_hub
END
CLOSE sql_cursor_hub;
DEALLOCATE sql_cursor_hub;
运行光标未添加数据,其显示的ID相同,显示的u = hubname不同,但未插入数据
如果我运行单独执行的SP,则会添加这样的内容
EXEC [dbo].[CreateHub] 'SGGSP30'
EXEC [dbo].[CreateHub] 'USGSP20'
您能帮我什么地方出问题吗
答案 0 :(得分:1)
您忘记在第二次访存中执行INTO
updatedb
locate *.o
您还应该注意参数声明,WHILE @@FETCH_STATUS = 0
BEGIN
set @sSQL = 'EXEC [dbo].[CreateHub] ' + @ItemsFromCSV -- AND OTHER Parameters
print @sSQl
EXECUTE sp_executesql @sSQL
-- This is changed
FETCH NEXT FROM sql_cursor_hub INTO @ItemsFromCSV
END
是varchar(200),但是存储的proc参数仅为varchar(100),而@ItemsFromCSV
的大小仅为100,但是您添加了{{ 1}}。
