我收到以下错误但无法弄清楚原因..
消息16915,级别16,状态1,过程client_myClientsProc,行 46个
已存在名为“cur_keywords”的光标 消息16905,级别16,状态1,过程client_myClientsProc,行 47个
光标已经打开。
然后,如果我再次尝试再次运行,那么
消息208,级别16,状态0,过程client_myClientsProc第49行 无效的对象名称'## CLIENTS_KEYWORD。
现在这是我要修复的旧代码,所以请耐心等待......

====================
按关键字代码获取客户
CREATE PROCEDURE [dbo].[getClientsByKeyword]
@Keyword varchar(max)
AS
BEGIN
SET NOCOUNT ON;
select
DISTINCT(clients.clientID)
from
Clients_Table clients
left join clientNumber cn on cn.clientid=clients.clientid
where
clients.activeind = 1
and (clients.Name like '%' + @Keyword + '%'
or clients.clientNum LIKE '%' + @Keyword + '%'
or cn.clientN like '%' + @Keyword + '%' )
END

OPEN
,FETCH
,WHILE
,CLOSE
和DEALLOCATE
放错地方了。试试这个重构的脚本。根据需要进行修改:
DECLARE @tempkeyword varchar(4000)
DECLARE @TempCount INT
IF OBJECT_ID('TempDB..##CLIENTS_KEYWORD') IS NOT NULL
DROP TABLE ##CLIENTS_KEYWORD
CREATE TABLE ##CLIENTS_KEYWORD(client_id int)
IF OBJECT_ID('TempDB..##TEMP_CLIENTS_KEYWORD') IS NOT NULL
DROP TABLE ##TEMP_CLIENTS_KEYWORD
CREATE TABLE ##TEMP_CLIENTS_KEYWORD(productid int)
SET @MYQUERY = 'SELECT clientID, Client_Name FROM MYCLIENTS WHERE ClientID IN ';
IF(@Delimiter<>'none')
BEGIN
DECLARE cur_keywords CURSOR FOR
SELECT value FROM SC_Split(@Keywords,@Delimiter)
OPEN cur_keywords
FETCH NEXT FROM cur_keywords into @tempkeyword
WHILE @@FETCH_STATUS = 0
BEGIN
FETCH NEXT FROM cur_keywords into @tempkeyword
INSERT ##CLIENTS_KEYWORD(client_id) exec getClientsByKeyword @tempkeyword
INSERT ##TEMP_CLIENTS_KEYWORD(client_id) exec getClientsByKeyword @tempkeyword
SELECT @TempCount=COUNT(client_id) from ##TEMP_CLIENTS_KEYWORD
IF(@TempCount<>0)
BEGIN
DELETE FROM ##CLIENTS_KEYWORD
WHERE client_id NOT IN(SELECT client_id from ##TEMP_CLIENTS_KEYWORD);
INSERT ##CLIENTS_KEYWORD (client_id)
SELECT client_id from ##TEMP_CLIENTS_KEYWORD;
END
END
CLOSE cur_keywords
DEALLOCATE cur_keywords
END
ELSE
BEGIN
print(@Keywords)
INSERT ##CLIENTS_KEYWORD(client_id) exec getClientsByKeyword @Keywords
END
SELECT @MYQUERY=@MYQUERY + '(SELECT * FROM ##CLIENTS_KEYWORD) ORDER BY NAME'
print @MYQUERY
EXEC SP_EXECUTESQL @MYQUERY

答案 1 :(得分:2)
之前存储过程是否有错误?看起来CLOSE
和DEALLOCATE
语句没有运行,如果代码遇到错误,可能会发生这种情况,因为代码中没有TRY..CATCH
或其他方法来确保游标已被妥善清除。尝试断开连接(或在同一连接中手动运行CLOSE
和DEALLOCATE
)并再次运行。
第二个错误可能是出于类似原因 - 清理不善。当您输入存储过程时,代码DROP
是临时表(如果它已存在)。 CREATE
虽然位于该声明的ELSE
部分。这意味着如果表已经存在,那么它将是DROP
ped并且永远不会重新创建。
答案 2 :(得分:1)
如果没有设置测试表,我不确定你的代码在做什么,但我认为你可以避免使用基于以下内容的光标。
;WITH C
AS (select clients.clientID,
clients.Name,
clients.clientNum,
cn.clientN
from Clients_Table clients
left join clientNumber cn
on cn.clientid = clients.clientid
AND clients.activeind = 1)
select value,
clients.clientID
from SC_Split(@Keywords, @Delimiter)
JOIN C
ON ( C.Name like '%' + value + '%'
or C.clientNum LIKE '%' + value + '%'
or C.clientN like '%' + value + '%' )
