hello,
I have aprox 70,000 words and want to store this data in DB, for this there are two ways as below:
1. add a single row that will have comma separated list of that 70,000 words. So the total records in the table will be 1
2. add all the 70,000 words as single single rows in table so total 70,000 rows in the table
what will be the best way to do this and why the solution is best. :)
Please explain... Thanks,
VinC

It depends on your business requirement( What are you going to do with this 70,000 words? )
If you intend to handle each word differently by joining them individually to some other table, then its better to store them as 70,000 rows
But as I said, we can't decide without knowing the business requirement.

Hi,
It depends on your requirement. If you to perform any operation on those words later like update etc. then its better you store those 70K words in 70K rows else you can store in a single rows of table with comma separated values.

You may want to consider Full-Text Search if your list is going to grow to 70 million+ words.
From MSDN:
A LIKE query against millions of rows of text data can take minutes to return; whereas a full-text query can take only seconds or less against the same data, depending on the number of rows that are returned.

In that case its better if you store these rows in 70,000 different rows so that you can do a JOIN
You cannot do a JOIN with the word if you store all the words in a single comma separated row.

Ok
then my suggestion is to store words in separate rows so that you can perform operation LIKE as you mentioned.

Thanks for the reply from all of you, but i need the specific reason why separate rows (70,000 rows) are more preferable to store in DB in place of comma separated list, its like i need to search the keyword from the list but that is also done quite easily with comma separated record.
Is there any documentation for such thing then it will be good for me to clear this view.
but thanks for the reply

Can you replicate your problem with the help of a CREATE TABLE statement, some sample data( say 5 rows ) and the query you will be running on the table?
It will then be easier for us to give you better suggestions.

INSERT INTO PseudoTable VALUES ('Tear,Bike,Monkey')
SELECT * FROM PseudoTable WHERE Item LIKE '%tea%'
1 row returned.
INSERT INTO PseudoTable VALUES ('Tear')
INSERT INTO PseudoTable VALUES ('Bike')
INSERT INTO PseudoTable VALUES ('Monkey')
SELECT * FROM PseudoTable WHERE Item = 'tea'
0 row returned.
