Question

存储过程是：

CREATE PROCEDURE CountUtily
    @domain varchar(50),
    @count int,
    @totalCount int OUT
AS 
BEGIN   
    SET NOCOUNT ON
    SET @totalCount=0

    IF (EXISTS (SELECT @totalCount = count 
                FROM FormFillerAuto2_DomainCount 
                WHERE domain = @domain))
    BEGIN
        SET @totalCount = @totalCount + @count

        UPDATE FormFillerAuto2_DomainCount 
        SET count = @totalCount 
        WHERE domain = @domain
    END
    ELSE
    BEGIN
        INSERT INTO FormFillerAuto2_DomainCount (domain, count) 
        VALUES (@domain, @count)
    END
END

错误：

＆＃39; =＆＃39;附近的语法不正确。关键字＆＃39; ELSE＆＃39;附近的语法不正确。

Answer 1

您的Select @totalCount = count不会返回bool。尝试在if评估之前设置@totalCount，并在if

中评估计数

CREATE PROCEDURE CountUtily
@domain varchar(50),
@count int,
@totalCount int OUT
AS BEGIN    
SET NOCOUNT ON
SET @totalCount=0

SELECT  @totalCount=count FROM FormFillerAuto2_DomainCount WHERE 

IF (@totalCount > 0)
begin
    SET @totalCount=@totalCount+@count
    UPDATE FormFillerAuto2_DomainCount SET count=@totalCount WHERE domain=@domain
end
ELSE
begin
    INSERT INTO FormFillerAuto2_DomainCount (domain, count) VALUES (@domain, @count)
end
end

请参阅EXISTS

指定要测试行是否存在的子查询。它返回   restricted SELECT statement如果子查询包含任何行，则会接受INTO，但不允许使用alter PROCEDURE CountUtily @domain varchar(50), @count int, @totalCount int OUT AS BEGIN SET NOCOUNT ON SET @totalCount=0; IF (EXISTS (SELECT [count] FROM FormFillerAuto2_DomainCount WHERE domain=@domain)) begin SELECT @totalCount=[count] FROM FormFillerAuto2_DomainCount WHERE domain=@domain UPDATE FormFillerAuto2_DomainCount SET count=@totalCount WHERE domain=@domain end ELSE begin INSERT INTO FormFillerAuto2_DomainCount (domain, count) VALUES (@domain, @count) end end关键字。

此处的问题是您无法在Exists中设置值。

尝试

{{1}}

我相信你缺少;来标记声明的结尾。同样，count是一个保留字，因此使用[]来逃避它。您发布的程序可以修改为

CREATE PROCEDURE CountUtily(
    @domain varchar(50),
    @count int,
    @totalCount int OUT)
AS BEGIN    
    SET NOCOUNT ON;
    SET @totalCount=0;
    SELECT  @totalCount=[count] FROM FormFillerAuto2_DomainCount WHERE domain=@domain;
    IF (@totalCount IS NOT NULL)
    begin
        SET @totalCount=@totalCount+@count;
        UPDATE FormFillerAuto2_DomainCount SET [count]=@totalCount WHERE domain=@domain;
    end
    ELSE
        INSERT INTO FormFillerAuto2_DomainCount (domain, [count]) VALUES (@domain, @count);
end

Answer 4

你使用count和totalcount变量使这个查询过于复杂;所有你不需要的。

因此，当字段“domain”与参数@domain匹配时，您希望更新“FormFillerAuto2_DomainCount”的“count”字段;或者你想插入它，如果它不存在。

好的，让我们使用@@ RowCount。

    UPDATE FormFillerAuto2_DomainCount SET [count] = ([count]+@count) where [domain] = @domain
If (@@ROWCOUNT > 0)
BEGIN
    return 1 --updated : or return whatever you need to show it updated
END
ELSE
BEGIN
    INSERT INTO FormFillerAuto2_DomainCount ([domain], [count]) VALUES (@domain, @count)
    return 2 --inserted : or return whatever you need to show it inserted
END

Answer 5

看起来你的更新有点搞砸..它应该是更新TABLENAME SET COLUMNNAME = VALUE 条件
