Are you getting this error as the result of trying to Insert data into a table?

how to fix depends on what you're trying to do post a bit or statement when it happened and what you're trying to do

If you're inserting data into a table it means that you are attempting to insert at least one item that has a non-numeric value into a column that is integer only

If you're selecting data with a where clause like WHERE field > 10 it means that the column field is not a numeric data type and at least one row in your table has a value in field that is not an integer

If you're trying to do math on a field that has character data you'll have the smae problem.

You can create the same type of problem in a case statement.

How to solve it, depends on where you problem comes from.

If its the insert, you have a choice of excluding non-numeric rows or changing your destination data type.
If its the where clause putting quotes around the comparision would help (provided your data supports the results) where field > '10'
If its math, you need to exclude non numeric rows
If its a case statement you need to rethink it

I am passing this thru ADO.

 Set prmId = CmdEquipItems.CreateParameter("@ID", adInteger, adParamInput, 4, lblmodID.Caption)
    CmdEquipItems.Parameters.Append prmId

when it hits this line ,produces runtime errror 3421-Application uses value of the wrong type for the current operation.

I am not getting the error in the UPdate process, just when inserting a new record....




My stored procedure


CREATE PROCEDURE [spu_TestInsertUpdateCatalog]
      @publisher      varchar(40),
      @book      varchar(20),
      @description      varchar(8000) ,
      @cost            float,
      @list            float,      
                @id            int,
      @user_name      char(20),

AS
     SET NOCOUNT ON
 
     if exists(select ID  from books where id = @id)
 begin
             UPDATE Books
             SET   publisher = @publisher
                            book      = @book,
                         descrip = @description,
                         cost =@cost,
                         list =@list,
                         vendid = @vendid,
                        Changed = GetDate(),
                         RowLastUpdtByOp = @user_name,
               RowLastUpdtDtTi = GetDate()
                 
     WHERE
                id = @id
end
     ELSE
Begin        
                 
 INSERT INTO Books
                     (
                     publisher,
                     Book,
            descrip,
                     cost,
                     list,
                               Changed,
                        RowLastUpdtByOp,
                    CreatedDtTi      
                     )
          VALUES
                     (
                     @publisher
                     @book,
                     @description,
                     @cost,

the label caption that's passed in is an implicit conersion to string what happens when you convert it first?

Set prmId = CmdEquipItems.CreateParameter("@ID", adInteger, adParamInput, 4, CInt(lblmodID.Caption))
    CmdEquipItems.Parameters.Append prmId

I get 'OVERFLOW' using the Cint(lblmodID.caption) when doing the edit/updates.

If I leave as is lblmodID.caption- It's oK no error.

I fixed it by changing the label to a textbox to read as

    Set prmId = CmdEquipItems.CreateParameter("@ID", adInteger, adParamInput, 4, txtID)
    CmdEquipItems.Parameters.Append prmId

This is OK now but the problem now is that it not writing/adding  the new ID and Publisher name in the Book table.
The rest of the data are entered/written to the Database though..
