Integration Services :: Convert Field Of VARCHAR To INT Datatype In SSIS 2014?

Nov 17, 2015

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.

Datatype Question Varchar(max), Varchar(250), Or Char(250)

Oct 18, 2007

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.

Varchar Datatype - Newbie Question

May 20, 2008

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?

NVARCHAR Vs VARCHAR Datatype And Performance

Aug 20, 2001

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?

Change Datatype From Varchar To Bigint Not Working

Nov 14, 2007


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:


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.
