Hi ,
I 'm working with visual studio 2005 and I have created an SQLServer Project.
I'm using the CLR functionality which comes with SQLserver 2005. This means that I can write VB.nEt code and use it inside Sqlserver 2005.So far so good.
I am now inside the .NET
I have created a Function(must remind you that I have created an SQLserver Project) which takes two string arguments. The date value in a string format and the string format.
In Our case the function returns a string.It will return a datetime although.
So we have
Dim Datetime_Val As DateTime = Nothing
Dim Date_Val As Date = Nothing
Dim StrTemp As String = ""
Dim StrDateTemp As String = Nothing
Dim StrTimeTemp As String = Nothing
Dim ls_return As String = Nothing
Dim lindexof As Integer
Dim Counter As Integer = 0
lindexof = 0
Select Case StrFormat
Case "DD-MM-YYYY HH24:MI:SS"
For Counter = 1 To 2
lindexof = StrDate.IndexOf("-", lindexof + 1)
Next
lindexof += 5
StrDateTemp = StrDate.Substring(0, lindexof).Trim
StrTimeTemp = StrDate.Substring(StrDateTemp.Length,
ls_return = StrDateTemp & " " & StrTimeTemp
End Select
The above is a simple code. As you can see I'm trying to convert the TO_DATE function ,which work with ORACLE, to make it work with SQLServer 2005.
I've been trying unsuccessfully to combine the variables StrDateTemp and StrTimeTemp into a datetime value. I used the following code but nothing
Datetime_Val = CDate(StrDateTemp & " " & StrTimeTemp)
Didn't work
Datetime_Val = Convert.ToDateTime(StrDateTemp & " " & StrTimeTemp)
Didn't work
Datetime_Val = DateTime.Parse(StrDateTemp & " " & StrTimeTemp)
Didn't work
Inside SQlServer I used this SQL statement
Select dbo.TO_DATE('31-12-1990 00:26:46','DD-MM-YYYY HH24:MI:SS')
But I am receiveing an error. I want to avoid changing all of my applications with a specific format.This sql statement without the dbo prefix I'm using in Oracle. I want to change the format. It is easier for me to put in my SQLs the dbo infront rather changing the complete SQL.
I have two questions . How am I going to create a TO_DATE function which Oracle uses and write something similar in SQLserver ?
And If I cannot do that how am I going to get the database 's datetime format and create with VB.NET the Datetime value from the two variables ?
My problem I believe is quite complex. I would be mostly appreciated if you could help me on this.
Thank you
