SQL 中未调用存储过程

Question

我有两个存储过程，一个调用 other.Though，其中任何一个在编译时都没有错误，但是在运行 SearchProcedure 上，outputprocedure 是不是从中调用的。我认为没有理由不调用它。 SearchProcedure 目前为止一切正常。请指导可能是什么问题。

我知道 OutputProcedure 没有被调用，因为我尝试在其中使用 Select 语句。

代码如下：

调用如下：

Exec SearchProcedure @firstname ='Simran', @middlename='kaur', @lastname = 'Khurana', @City='Delhi'

程序：

CREATE Procedure OutputProcedure
( 
 @LastNameFromUser nvarchar(20) = null, 
 @LastNameFromTable nvarchar(20), 
 @MiddleNameFromUser nvarchar(20) = null, 
 @MiddleNameFromTable nvarchar(20) = null, 
 @CityFromUser nvarchar(20) = null,
  @CityFromTable nvarchar(20) = null,
@Percentage int out
  )
AS
BEGIN
select 'OUTPUTPROCEDURECALLED'
declare @maxvalue int
DECLARE @variableTable TABLE (
    idx int identity(1,1),
    matchvalue nvarchar(15))

    INSERT INTO @variableTable(matchvalue) values ('MiddleName')
    INSERT INTO @variableTable(matchvalue) values ('LastName')
    INSERT INTO @variableTable(matchvalue) values ('City')

    SELECT * FROM @variableTable 
DECLARE @counter int
declare @sql nvarchar(100)
declare @sql2 nvarchar(25), @finalResult nvarchar(100)
declare @sql3 nvarchar(300), @tempresultStore nvarchar(20), @temp int, @temp2 int, @average int


SET @counter = 1
SELECT @maxvalue = (SELECT MAX(idx) FROM @variableTable)

select @maxvalue as 'MAXVALUE'
WHILE(@counter <= @maxvalue)
BEGIN
    DECLARE @colVar nvarchar(15)

    SELECT @colVar = matchvalue FROM @variableTable WHERE idx = @counter
    set @sql = 'declare' +' ' + '@Temp'+ @colVar 
    exec @sql
    select @sql as 'SQLFORDECLARATIONS'

    set @temp = CHARINDEX(' ',@sql)
    select @temp as 'resultofcharindex'
    set @temp2 = @temp + 1
    SELECT @temp2 AS 'AFTERADDING1'
    set @tempresultStore = Right(@sql, @temp2)
    SELECT @tempresultStore AS 'FINALCUTPART'
set @sql3 = 'SET ' +  @sql2 + '= set ' + ' ' + @tempresultStore + '=' + 'dbo.[Match' + @colVar + '](' + @colVar + 'FromUser' + ',' + @colVar + 'FromTable' + ',' + 0 + ')' 
EXEC @sql3   
select @sql3 as 'check sql query formed'

set @finalResult = @finalResult + @sql2
select @finalResult as 'SUM'
    SET @counter = @counter + 1
    select @counter as 'COUNTERVALUE'
    END
    set @Percentage = @finalResult/@maxvalue
    SELECT @Percentage AS 'FINALRESULT'
RETURN 
END

Answer 1

SearchProcedure 中是否缺少设置变量 fn 的代码；你用

打开光标

declare  c Cursor local static Read_only 
 for 
SELECT * from dbo.Patients where firstname = @FN

只是我看不到@fn 的设置位置；如果游标没有行，则不会调用第二个过程，因为循环不会运行.
