Hello Experts,

With regards to my previous question, I am now having no values being returned in @PC_PatternID variable.

Please can you advise if I am doing something wrong in my SP?

thanks

define @pc_patternID as output parameter like this
ALTER PROCEDURE [dbo].[procRegisterPattern] 
        -- Add the parameters for the stored procedure here     
@PC_ID                  INT,    
@PC_PatternName         CHAR(100) output,      
@PC_Value               CHAR(100)
AS
BEGIN   
-- SET NOCOUNT ON added to prevent extra result sets from       
-- interfering with SELECT statements.  
SET NOCOUNT ON; 
DECLARE @PC_PatternID int       
SET @PC_PatternID = -1  
SET @PC_PatternID = (SELECT PC_PatternID FROM PC_Pattern WHERE [Name] LIKE @PC_PatternName)   -- Error at this line
        IF @PC_PatternID < 0 BEGIN
                SET @PC_PatternID = (INSERT INTO PC_Pattern([Name]) VALUES (@PC_PatternName) SELECT @@IDENTITY)  --- and this line
        END     
INSERT INTO PC_Match(PC_ID, PC_PatternID, PC_Value)     
VALUES (@PC_ID, @PC_PatternID, @PC_Value)
END
 
 
 
Incorrect syntax near the keyword 'INSERT'.
Incorrect syntax near ')'.

you can call your SP like this.

declare @n char(100)
exec [dbo].[procRegisterPattern]  @pc_id=1,@pc_patternName=@n output,@pc_value ='any value you have'
select @n --value will be returned to @n
0

Hi RiteshShah

Thanks for your input. I dont want to return anything back from this SP.

All I want to do is to get the Patter_ID matching the Pattername from the PC_Pattern table and insert into the PC_Match

I am not getting correct value for PC_PatternID in the INSERT statement below

INSERT INTO PC_Match(PC_ID, PC_PatternID, PC_Value)    
VALUES (@PC_ID, @PC_PatternID, @PC_Value)

Instead of adding
id    pat_id   value
10     1           Alice

its adding

10     19        Alice

19 : I believe is the number for the total number of records being added to the table...

I hope you understand what I am trying to say here?

thanks

ALTER PROCEDURE [dbo].[procRegisterPattern]

@PC_ID                  INT,    
@PC_PatternName         VARCHAR(100),      
@PC_Value               VARCHAR(100)
AS
BEGIN   
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON; 
DECLARE @PC_PatternID int       
 
SELECT @PC_PatternID = PC_PatternID 
  FROM PC_Pattern 
 WHERE [Name] LIKE @PC_PatternName
 
IF @@ROWCOUNT = 0
BEGIN
  INSERT INTO PC_Pattern([Name]) VALUES (@PC_PatternName) 
  SET @PC_PatternID = SCOPE_IDENTITY()
END     
INSERT INTO PC_Match(PC_ID, PC_PatternID, PC_Value)     
VALUES (@PC_ID, @PC_PatternID, @PC_Value)
END

you have used like in your SP but didn't use any wildcard character. can't you do something like this?



ALTER PROCEDURE [dbo].[procRegisterPattern] 
        -- Add the parameters for the stored procedure here     
@PC_ID                  INT,    
@PC_PatternName         VARCHAR(100),      
@PC_Value               VARCHAR(100)
AS
BEGIN   
-- SET NOCOUNT ON added to prevent extra result sets from       
-- interfering with SELECT statements.  
SET NOCOUNT ON; 
DECLARE @PC_PatternID int       
 
SELECT @PC_PatternID = PC_PatternID 
  FROM PC_Pattern 
 WHERE [Name] LIKE '%' + @PC_PatternName + '%'
 
IF @@ROWCOUNT = 0
BEGIN
  INSERT INTO PC_Pattern([Name]) VALUES (@PC_PatternName) 
  SET @PC_PatternID = SCOPE_IDENTITY()
END     
INSERT INTO PC_Match(PC_ID, PC_PatternID, PC_Value)     
VALUES (@PC_ID, @PC_PatternID, @PC_Value)
END

Hi

Thanks again, OK I have tried with the wild cards as suggested above,

SELECT @PC_PatternID = PC_PatternID
  FROM PC_Pattern
 WHERE [Name] LIKE '%' + @PC_PatternName + '%'


Because its not returning any result, the following statements is getting executed...

IF @@ROWCOUNT = 0

Is the above syntax is correct to assign the value to @PC_PatternID ?

Please advise

thanks

or you can do something like this as if there is nothing return from your query, there will be something <0 in your patternID.
ALTER PROCEDURE [dbo].[procRegisterPattern] 
        -- Add the parameters for the stored procedure here     
@PC_ID                  INT,    
@PC_PatternName         VARCHAR(100),      
@PC_Value               VARCHAR(100)
AS
BEGIN   
-- SET NOCOUNT ON added to prevent extra result sets from       
-- interfering with SELECT statements.  
SET NOCOUNT ON; 
DECLARE @PC_PatternID int       
set @PC_PatternID=-1
SELECT @PC_PatternID = PC_PatternID 
  FROM PC_Pattern 
 WHERE [Name] LIKE '%' + @PC_PatternName + '%'
 
IF @PC_PatternID <= 0
BEGIN
  INSERT INTO PC_Pattern([Name]) VALUES (@PC_PatternName) 
  SET @PC_PatternID = SCOPE_IDENTITY()
END     
INSERT INTO PC_Match(PC_ID, PC_PatternID, PC_Value)     
VALUES (@PC_ID, @PC_PatternID, @PC_Value)
END
