Question

我有两个存储过程，一个调用另一个。尽管编译中没有任何错误，但是在运行SearchProcedure时，outputprocedure不会从中调用。我看到没有理由不被召唤。 SearchProcedure到目前为止工作正常。请指出可能存在的问题。

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

以下是代码：

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

在SearchProcedure中，缺少设置变量fn的代码;用

打开光标

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

只有我不知道@fn的设置位置;如果光标没有行，则第二个过程不会被调用，因为循环不会运行。

存储过程未在SQL中调用
