Error converting data type varchar to numeric



I am trying to execute below query.



CAST('123,456,789.00' AS DECIMAL(11,2))

"IN" operator and error converting data type varchar to numeric



I hope someone can help me figure this out please...

I have this query that returns some student data - specifically the student's names, and some classes they're enroled in. What I'm trying to do is return multiple rows using the LIKE operator.

However when I run it and plug in the parameters I get the errror - "Error converting data type varchar to numeric". This error doesn't occur when there is only ONE studentId. Only when there are multiple studentIds. I know it's to do with the string of studentIds being passed, but I'm not sure how to fix it?

Should I be using varchar as the datatype to pass the studentIds? Or do I need to cast this as something else?

Any ideas, much appreciated.



	@StudentIds varchar(8000),
	@ProfileId numeric,
	@Fname varchar(50) OUTPUT,
	@Lname varchar(50) OUTPUT,
	@ClassName varchar (100) OUTPUT,
	@ClassName2 varchar (100) OUTPUT,
	@ClassName3 varchar (100) OUTPUT,
	@ClassName4 varchar (100) OUTPUT,
	@Class numeric OUTPUT,
	@Class2 numeric OUTPUT,
	@Class3 numeric OUTPUT,
	@Class4 numeric OUTPUT


@Fname = Fname, @Lname = Lname, @ClassName = C.ClassName, @ClassName2 = C2.ClassName, @ClassName3 = C3.ClassName, @ClassName4 = C4.ClassName,

Error converting data type nvarchar to numeric in Store Procedure execution



When I execute a Store Procedure via 'EXEC sp_XXX @p1, @p2' I'm getting this error 'Error converting data type nvarchar to numeric'.

After diggin into the TSQL code I have found that there's a field (type: nvarchar(200)) breaking the execution and resulting on the error.

If I query the table and the specified field with the same parameters as the Store Procedure the results are ok! If I execute the same code as the Store Procedure with the same parameters values the results are ok. The error only happens when executing the Store Procedure.

Any idea ?

Thanks in advance,

Gustavo Brian


If I cast the field to a smaller size value, as nvarchar(80), it works, but of course with data truncation.


Syntax error converting varchar value to a column od data type int


Hi everyone,

I'm having a problem where I've created a stored procedure with a dynamic ORDER BY clause and it's returning a syntax error:

Server: Msg 245, Level 16, State 1, Procedure usp_OrderBy, Line 4

Syntax error converting the varchar value 'Closed' to a column of data type int.

Here is the code that I'm trying to execute. It works fine if I take out the ID line:

CREATE PROCEDURE [Task_User].[usp_OrderBy]
  @orderBy varchar(100)
  SELECT ID, Status, PostedBy, Assigned, Subject
  FROM mainTable
    WHEN @orderBy = 'ID' THEN ID --When I take this out, it works
    WHEN @orderBy = 'Status' THEN Status
    WHEN @orderBy = 'PostedBy' THEN PostedBy
    WHEN @orderBy = 'Assigned' THEN Assigned
    WHEN @orderBy = 'Subject' THEN Subject
Any ideas as to what I can do to fix it?
