Hi all,
I am using a varchar datatype for PIN number to handle zero at start. Now i want to do mathematical calculation to encrypt the PIN so i need to convert that varchar datatype to int so that zero should not be discarted after conversion. i.e. 0123 and 123 must not be treated as same PIN.
Please kindly give me a way out. I am using RSA encryption.
Thanks in anticipation.
Haider Abbas.

I have an Image data which I need to convert to string data.
Tried "Select CAST(CONVERT(nchar(1000),CAST( body AS varBINARY(1000) )) as VARCHAR(1000)) as TD
FROM Table",
But it returns a set of question marks.
(ex: ????????????(?????????????????????†????????????????????????????????
???????????????????????????????????????????????8??????????????????...)

Hi I have a varchar(8000) and currently XML files are stored in varchar(8000).Some times when i am doing manuplactions in my varchar column i am getting with special characters error. so now i want to keep my column varchar(MAX) and when i am doing calculations i will convert my varchar datatype to xml datatype. By doing this i hope there wont be any special character problems.
When i am doing calculations with the wellformed xml i am getting error for both convert and cast methods as below
I am trying to do convert(xml,MyVarcharColumn)
Implicit conversion from data type xml to nvarchar is not allowed. Use the CONVERT function to run this query.
Also i tried with casting and getting same problme. is there any way to convert
please suggest me
Thanks

I'm trying to convert a column in my source table of datatype varchar(6) to a column of datatype int in my destination. I tried using the Derived Column/Data Conversion transformations but none of them worked. So, I tried using the following C# (credits to the original poster) and getting an error during compilation.
Note: "MyCol" is the Input Column I've specified in the Script Component and "CleanCol" is the Output column I've specified as datatype [DT_I4].
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
int colOut = 0;
if (!Int32.TryParse(Row.MyCol, out colOut))
{
Row.CleanCol_IsNull = true;
} else {
Row.CleanCol = colOut;
}
}
The best overloaded method match for 'int.TryParse(string, out int)' has some invalid arguments
The other expression I've tried was:
ISNULL(MyCol) ? (dt_i4)"" : (dt_i4)MyCol
From the above code, you might have understood that the source field has some blank records as well in the MyCol field.
What is the best possible way to do the conversion from a String to Int or fixing the error from the above.

I have a table that contains a lot of demographic information. The data is usually small (<20 chars) but ocassionally needs to handle large values (250 chars). Right now its set up for varchar(max) and I don't think I want to do this.
How does varchar(max) store info differently from varchar(250)? Either way doesn't it have to hold the container information? So the word "Crackers" have 8 characters to it and information sayings its 8 characters long in both cases. This meaning its taking up same amount of space?
Also my concern will be running queries off of it, does a varchar(max) choke up queries because the fields cannot be properly analyzed? Is varchar(250) any better?
Should I just go with char(250) and watch my db size explode?
Usually the data that is 250 characters contain a lot of blank space that is removed using a SPROC so its not usually 250 characters for long.
Any insight to this would be appreciated.

Is there any method to find out the size of an image datatype currently in the database. For example I have 2 tables that contain the same image, but the archive table is not displaying the same as the main. I am thinking the image file was corrupted somehow but don't know how to check this out.
Any ideas?

I have a table with an IMAGE datatype. Without using xp_cmdshell and bcp, is it possible to get this image to disk? We do have the OLE procedures enabled so I can use those to create in instance of the Scripting.FileSystemObject and write to disk but how do I convert the image datatype to something I can store on disk and it actually be a readable format? If it helps, we only store this particular field in JPEG format in the database.

Hi all,I have a database with 40GB of binary objects stored in image columnsin two tables.Our database server is also used for another 15 databases.SQL Server caches the image-column, causing the cache-hit-ratio todramatically decrease, since fetching a couple of binaries from theimage-column uses up thememory, and throws other cached objects out of the cache.Is there a way, and could someone tell me how, to avoid caching ofspecificcolumns/tables?Regards///Magnus
