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.
I have a table Table1 which has a Col called "Msg" datatype image<binary>. Msg alreay has the plain text or RTF text as a image datatype (binary)If I execute the following query "Select Msg from Table1 where id =3" then this query is returning the following ASCII/Binary data.Msg = "0x7B5C727466315C616E73695C616E7369637067313235325C64656666305C6465666C616E67313033337B5C666F6E7474626C7B5C66305C6673776973735C66707271325C66636861727365743020417269616C3B7D7B5C66315C6673776973735C66707271325C666368617273657430204D6963726F736F667420"Can any body tell me how can I convert the above binary data to plain text from my query?Thanks for any reply.

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
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.
For the life of me I cannot figure out why SSIS will not convert varchar data. instead of using the table to table method, I wrote a SQL query so that I could transform the datatype ntext to varchar 512 understanding that natively MS is going towards all Unicode applications.
The source fields from Access are int, int, int and varchar(512). The same is true of the destination within SQL Server 2005. the field 'Answer' is the varchar field in question....
I get the following error

DTS used to be a very strong tool but a simple import such as this is causing me extreme grief and wondering of SQL2005 is ready for primetime. FYI SP1 is installed. I am running this from a workstation and not on the server if that makes a difference...
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.
I have a field in a table that stores date of birth. The field's datatype is char(6) and looks like this: 091703 (mmddyy). I want to convert this value to a datetime datatype.
What is the syntax to convert char(6) to datetime?

When creating tables: If varchar expands according to how long the actual string is in each case, then why not set the varchar max characters very high, rather than be conservative about it? For example, if you think your names will only ever be 30 chars you could set that column to varchar(30).But -- why not go ahead and set the column to varchar(100) anyway to be safe? Or is there some hidden storage cost to using 100 rather than 30 max chars?
We have few stored procedures that use nvarchar datatype, this was not issue on SQL server 7.0 but in 2000 becomes a big issue. For example query that runs for 3 minutes in SQL server 2000 by replacing NVARCHAR to VARCHAR the same query runs for 2 seconds. The biggest challenge that I have deals with tables and user-defined datatypes of NVARCHAR that has been bounded to the table. How can I alter those without data corruption?
Session("matricN") = Trim(TextBox1.Text) Dim txtValue As String txtValue = Session("matricN") da = New SqlDataAdapter("select MatricNumber,Name, Roles from Register where MatricNumber = " & txtValue, addRoleConn1)
MatricNumber is in varchar(50) datatype,, the errror says there is a syntax near "="
I would like to change the datatype on a particular column from varchar to bigint across 100's of tables within a database.
I have the command ready which is:
ALTER TABLE tablename ALTER COLUMN columnname BIGINT
The problem happening is that it seems there are constraints across all the columns in every tables.
The error message is:
Server: Msg 5074, Level 16, State 1, Line 1 The object 'DF__tablename__columnname__0ABD916C' is dependent on column 'columnname'. Server: Msg 4922, Level 16, State 1, Line 1 ALTER TABLE ALTER COLUMN columnname failed because one or more objects access this column.
I understand that if I delete this constraint, then it will let me modify the datatype of the column, but since there are tons of them and they are randomly named, how do I achive changing the datatype across multiple tables in bulk.
Why can varchar datatype variable only 4000 byte? For example: in a storedprocedure declare @aa varchar(8000) ...... while select @aa=@aa+@otherinfo end when the length is more than 4000 ,the data in the behind will be lost
Hi, I have a excel file and i am trying to import zip codes to the database... but the some of the zip codes start with 06902 but the excel file treats them as float but i want to treat them as varchar...

The challenge that the spectrum of varchar lengths across the table. I have one attribute that requires varchar(max) and all other attributes (about 40) are varchar (200).
I created two fields (Old_ValueAtrLong and New_ValueAtrLong) dedicated for the one attribute that is a varchar (max). I was trying to avoid storing [Status] for example that's a varchar(200) in a field that is varchar(max). Is this the right approach? Or are there other recommendations in how to handle storing the data in the most efficient manner?

Hi all, There are several columns called enabled with a char datatype in my database. One enabled column per table. These columns either have a value of T or F (true or false), depending on whether they're enabled or not. I want to change these columns to a bit datatype and insert the relevant value of true or false... I guess the best way to do this is to add a new column to a table with a bit datatype, and based on the value in the current enabled column, insert TRUE or FALSE. Anyone ideas on the best way to accomplish this? Thanks.
I have a number of bit datatypes ( Boat types: Cruiser, Sportfisher, Megayacht, Sailboat) that I would like to place in a text box and do away with the individual selections. For instance, some marinas cater to "Cruiser", "Megayacht" and "Sailboat" while others include the "Sportfisher" also and there are many other combinations of vessels. I am stumped at how to write a query that takes the existing "True" values for each boat type and places them in a text box in the form of " Cruisers, Megayachts, Sailboats" .
