Error 0xc02020a1: Data Flow Task: Data conversion failed

[Sharif Islam]

Hi,
I am new to SQL 2005. My text import with DTS in SQL 7 ( my previous
version) works fine. I check the column URL, the data seems to be ok. I
set it to varchar and length 255 ( I tried higher as well). Any idea?

Thanks it worked. But this time I changed the size 1000, (500 didn't work)

Here's what the post said:

"The flat file defaults initially all columns to characters with length
of 50. You can change this by going to the “Advanced” page of the Flat
File connection page and change the length manually, or you can click on
"Suggest Types..." to get suggested column metadata attributes based on
sampling a certain number of rows from the file."

I tried this and it worked to an extent. The issue is that my raw data as a lot of free form text fields and the only way to make this work is to limit the number of text fields. The "Suggest Types" seems to take an average of what data is stored and can only be used on a flat file which makes it even more challenging if your data is not clean.
