Error converting data type varchar to uniqueidentifier

I am trying to run a stored procedure. This is the line I am having problems with....

, @CustId uniqueidentifier

Right now I have it as.....


I do not want it to be fixed. I would like it to run on all customers, not just a specified Unique ID.

I tried the following......

,' LIKE '%%'
, 'Null'

Now I am stuck.

Please advise.....

Can't you just omit it from the WHERE clause? I.e. suppose you have a query like this:
SELECT custName, custAddress FROM customer
WHERE custID = @custID

Open in new window

If you want to select all customers use this:
SELECT custName, custAddress FROM customer

Open in new window

It is actually as part of a store procedure.  

Below is a section of the stored procedure.

@XMLDataSelection text
, @ReportType smallint
, @RankBy smallint
, @RankValue smallint
, @FromDate1 datetime
, @ToDate1 datetime
, @FromDate2 datetime
, @ToDate2 datetime
, @CoType varchar(5)
, @LOBCat smallint
, @TranReporting smallint
, @CustId uniqueidentifier

Below is me passing the parts into the stored procedure to get it to run....

sps_Stored_Procedure (

'<Root><RowId Code="(All)" Type="9" /></Root>'
,<<ReportType [Numeric]>>
, <<RankBy [Numeric]>>
, <<RankValue [Numeric]>>
,'2010-01-01 12:00:00'
,'2013-01-01 12:00:00'
,'2010-01-01 12:00:00'
,'2013-01-01 12:00:00'
, <<LOBCat [Numeric]>>
, <<TranReporting [Numeric]>>
, <<SortSequence [Numeric]>>
, '!*R'

As you can see I have the uniquie ID hard coded. That will not work because I want the report to run for all customers. Some of the parameter are hard coded also so I do not have to type the dates over and over. The <<Prompt>> I can fill in different parameters.

But when I take the , @CustId uniqueidentifier and turn it into
 <<CustId uniqueidentifier [Text]>> I get the error of ...Error converting data type nvarchar to uniqueidentifier.:

The program will not close and allow me to run the report because of the error. It understands the following formats. (Numeric, Text, Date, Datetime, Time, Boolean ) Numeric gets me the same error.
In this case you should have a predefined uniqueidentifier value that will be understood by both the stored procedure and your program as a "value for all", i.e. it could be

Then in your stored procedure in place of your " AND custID = @custID" statement write this:
... AND (custID = @custID OR @custID = '00000000-0000-0000-0000-000000000000')

Open in new window

This way whenever the calling program passes '00000000-0000-0000-0000-000000000000' all customers will be returned

ok. I try the following and get Incorrect Syntax near 'AND'

,AND (custID = @custID OR @custID = '00000000-0000-0000-0000-000000000000')

I try this and get looking for a [Text] or [Nummeric]

,<<AND (CustId = @CustId OR @CustId = '00000000-0000-0000-0000-000000000000')>>

I try this and get : Error converting data type nvarchar to uniqueidentifier

<<AND (CustId = @CustId OR @CustId = '00000000-0000-0000-0000-000000000000'[Text])>>

here is a snip from the book

SQL Stored Procedure
Enter the name of the stored procedure directly here. If a parameter needs to be passed in, include it in your local databases syntax. Omit any “CALL” verbs, just enter in the procedure name. Example: MYPROCEDURE(‘Value1’,10)

Hold on. You did not understand me. The "AND (custID = @custID OR @custID = '00000000-0000-0000-0000-000000000000')" needs to be applied to the code inside your stored procedure. Your program just needs to call it with a value of '00000000-0000-0000-0000-000000000000' as a parameter

You are correct, I do not understand. I am an accountant,  not IT. I get stuck doing this because no one else can help. I can not edit the Stored Procedure if this is what you are saying.

I have to add a line into the program in the order that the procedures are called. For example, this line , @ReportType smallint is translated to ,<<ReportType [Numeric]>>.... The <<>> renders a prompt for me. So when I run it, it ask me to enter a number.

This line , @CoType varchar(5) is translated to ,'N'....... N will always be the answer so I hard code it.

I'm not sure if I am explaining it correctly or not understanding what you are asking me to do.
I think in this case you will not be able to achieve what you want. Both of us don't know what the stored procedure is doing. However, if you can get someone to change the stored procedure as I described, you will be able to select all customers.

The stored run a report in out ERP system. There is an "window/panel" that pops up with all the selectors in drop down filters, radio buttons, etc like a normal program. The window prompts the same store procedure, so I can not change it.

I am using the program of Informer to run the same procedure so I can create calc columns, hide some of the results, etc... That way I do not have to re-do it every week in excel.

I can also use Informer to schedule the report. Informer also has built in BI that I can use.

I guess I am back to them for help...

What about wild cards or convert/cast to change the UID to Text.
Even if the wildcards are supported (e.g. in case of a character string) it depends on the query implementation inside the stored procedure. E.g. for strings you could write:
WHERE custName LIKE @custName

Open in new window

In this case you could specify @custName as 'SM%' and it will find all Smiths, Smirnoffs, ets.
However, if the query has a condition like this:
WHERE custName = @custName

Open in new window

then you will not be able to use wildcards.

OK, not what I really wanted to hear, but I got a good education from the situation. Thanks.
