Not sure if this should be in SQL or .NET but as I'm doing this in asp.net I figured here..I'm trying to insert '00' into a varchar column of my database, when I do this its actually in the database as '0'... if I do '05' or '15' or '30' then its fine.

View 5 RepliesI have a little problem developing a SQL Select Statement on a column that is formatted pretty badly. Firstly, the Database has already been created and filled with Data in a Test Environment, I'm not sure if the format is the same or has been updated in Production but since I'm only able to work with the Test Environment right now I'm stuck with using what I have. The Column in one Table shows a Snapshot of a clients account which is set to VarChar(50) but the actual data in the column is formatted like a money format (with a $ and decimal point so for example "$5,000.00" would be an entry in one Row).
What I'm trying to do is a create a WebService that will be used in a iPhone Application and one of the Methods needs to just give a quick display of the total value of all Clients with each specific company but I can't perform a SUM function on a VarChar column and I've tried to CAST and CONVERT the column into money, int, decimal and just about every format I can think of but I keep getting an error stating that I convert the data type varchar to which ever one I'm trying. I think it has something to do with the $ already listed in the Column, so I wanted to know what I could do to either remove the $ sign (like a Trim option) or if there is a better way of doing this that I can't think of. I know the best option would be to convert the column to the appropriate format but as I said, this was a previously designed system and I'm not sure if the Production area is the same (most likely not).
Here's what I've tried so far:

View 3 RepliesI have a grid view with manual sorting. In some cells, the data are numeric and datetime. But due to some constrains, the data type on tables are varchar. The problem here is when I sorting those numeric data, it is treated as varchar.Eg: 1, 12, 13, 2, 23, 3, ...But I wanted the order to be: 1, 2, 3, 12, 13, 23, ...I have tried these method, but it doesnt works.

I have heard that even though the maximum varchar size is 8000, that we should not go higher than 7500 for the size value. What is the logic behind this advice?

How can I get rid of the Pad characters?
I have a form with many form fields and controls, with some offering an "other" if a value does not meet the needs for the user. How can I bind the sql insert so that it will take the ddl selection along with the txt field selection for the "other" value? Even if the txt field is empty it should not be a big deal since the ddl would provide something other than null. Since the column in the db does not allow nulls. I'm using asp.net (vb) 3.5 sp1

View 7 RepliesI'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.

Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
