CSV vs Text delimited file

In the case where data files are required to be gathered from different sites, then uploaded into a SQL Server database, which is better to use and why? CSV files or Text delimited files (with a pipe delimiter for example)?

Agreed, easy to work with the data in .csv format

Heres how to load the data in mysql

LOAD DATA INFILE
'Drive:/path/filename.csv'
INTO TABLE yourtable
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n';

If you want to exclude the headings(the first line or lines)

EG:

LOAD DATA INFILE
'Drive:/path/filename.csv'
INTO TABLE yourtable
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;

But in what way is the CSV better than text files?
Would you please specify cases where CSV was better than Text?

CSV is essentially a text file

I actually tend to use pipe delimited for my imports/exports these days as i find data is a lot less likely to contain pipes than contain commas, quotation marks etc (which potentially breaks the file!)

CSV and other text format other tan XML have same processing time. In both cases databse search for delimiter to seperate field values.
There is one drawback in using CSV when your data columns has commas ","  then u get unexpected results. While in using other delimitters (like special cahracters as pype "I" sign ) you can avoid such errors.

CSV stands for Comma Seperated value text file. They are easy to read in raw format, generally regarded as industry standard.

CSV is a text file, the reason they are useful is because they are easily imported into multi column formats such as spreadsheets and databases.

CSV or TXT file... its same thing.

CSV...
its easy to create CSV file, say if you want your application to generate a CSV file and would like Ms Excel to open it by default. as mentioned above problem is with extra "," in the column values. this coul dbe avoided by text text qualifers( " around text).

TXT

Same process time as CSV, only thing is it has .txt extension, and would need to imported into MS EXCEL.

The extension is also not important. I often use .dat extension for my pipe delimited files.

Using text qualifiers doesn't always help in CSV (imagine i have a field which also contains those text qualifiers!

dirkvdoCommented:
@tickett : single character delimiters are indeed not always possible. Therefore, if I can (i.e. I scripted the creation of the file myself), I use a multi-character delimiter (usually something like %/µ). These files can also be read by Excel, but you need two steps more to import them (open the file with excel, select first column and perform "text to columns" action, using the multi-character delimiter you used ... et voilà).
With the instruction given by kingjely, you'll have to replace the ',' in the line
FIELDS TERMINATED BY ','
by something corresponding with the chosen multi-character delimiter.

@dirkvdo: true- but you have to be careful opening the file with excel (it has a nasty habbit of "guessing" the file is .csv and automatically splitting columns. when you then do your "text-to-columns" operation your data gets a bit messed

but i expect we've covered what @sasi_kmr wanted to know :)
