convert ado.net datatype to sql datatype
I have included the code that converts ado.net datatype to sql datatype. The columns belong to the dataset. However I want to know if there is a more direct method of dealing with this instead of multiple if then else or switch case statements.
If column.DataType.ToString = "System.Double" ThencolumnType.Add("bigint")
ElseIf column.DataType.ToString = "System.String" ThencolumnType.Add("ntext")
ElseIf column.DataType.ToString = "System.DateTime" ThencolumnType.Add("datetime")
Else : columnType.Add(column.Dat...CLR.NET datatype for decimal is System.String or Decimal

...SQL in .NET question
How do i use the LIKE and the wildcards in a search in .NET (using c#)
example in straight SQL:
SELECT * FROM myDB WHERE LastName LIKE '%Jo%'
if i try and use it in .NET like follows:
SELECT * FROM myDB WHERE LastName LIKE %@MyVar%
I get an error.
SELECT * FROM myDB WHERE LastName LIKE @MyVar
and then prepend and append '%' characters to the string you are passing in.Starting with ASP.NET 2.0? Look at:Programming Microsoft Web Forms My Blog

I'm running WinXP pro 32-bit, meaning I've got the version
1-dot-something of .NET that XP came with. I've been looking for
various softwares, and more and more often come across .NET version 2
being prerequisite. No urgency for me re. my questions to this group -
so far I have just decided to hit the red X on those download pages -
but the desire for this newer version of .NET seems to be growing for me.
Firstly, according to my (limited) research, newer .NET versions are
inclusive of the previous ones, and the current version seems to be 3.5.

wrote an insert for a C#.Net web app. The insert works fine, except if there are appostrophies (spelling) for example:
this isn't a problem
this isnt a problem
the second one will work the first will not.
The info is going into a sql server database as text(16), the same result occurs with char.
I believe you'll need to use an escape character "\", so something like this:
"this isn\'t a problem"
Also, you should try to use stored procedures or at the very least paramater queries. Both of those would solve your problem as well."I would l...Converting a gridView using an Sql Datasource to a gridview who is not using an SQL DataSource

...SQL Question: Updating from decimal to integer
Ok so I have an editable grid containing a delivery driver's route (delivering newspapers). One of the fields is "Delivery Order" (used to order the delivery sequence). So the table looks like the followingLocationID, DeliveryOrder, Address, EtcMy problem is when the user updates the delivery order by "adding a new delivery location" they have to enter a decimal to fit it in the spot they want. For example, if they have a location that needs to fit between the first delivery location (Location 1) and the second (Location 2) the user would need to enter a delivery orde...A question about the Sql Server Decimal Data Type
I am a little confused about the Decimal Data Type in SQL Server.
Why is the following SQL Ok:
declare @foobar Decimal(6,2)select @foobar = 123.00select @foobar
Yet this SQL throws an arithmetic overflow error:
declare @foobar Decimal(6,4)select @foobar = 123.00select @foobar
Didn't I make the decimal larger in the second example? I also have one other question (which was the reason that I was playing around in the first place). I have read that the 'precision' is the maximum number of digits that can be stored to the left and to the right of the decimal point. T...Possible Bug in SQL DataLayer (decimal datatype)
I've been working on a custom module for my company. I'm having an issue in 2 of my tables.
I have datatypes of Decimal in my tables, Everytime i call
Plan = CType(CBO.InitializeObject(Plan, GetType(HostingPlansInfo)), HostingPlansInfo)
i get a weird reflection error. I guess i'm wondering if the datalayer can support a decimal datatype and tinyint datatypes. I've re-generated all my stored procedures, business objects, and the dataproviders. Any idea on this?
Error: Hosting Plans Admin is currently unavailable.
