fairly simple question with no clue as to the answer. I have a column in a tabe that was created as nchar(10). Now the powers that be want a little more information in that column (store identifiers) and I need to change the nchar(10) to nchar(50). Did that,saved it with no errors or warnings, but when new information is entered the database is truncating the data to (10) still for that column. How do I fix this? any ideas? It is the database that is doing it as the code that enters the information does not care how many characters are in the string its inserting. Its a SQL 2008 r2 database BTW.
edit:
I found the issue, it WAS in the code I forgot that my app had to set a scalar variable when doing the insert etc etc... And I never changed it from (10) there... duh.. leaving the post instead of deleting in case some other noob makes the same mistake as me... lol

Hi,
Good that you found the solution. However, few other things in this post that made me wonder:
- do you really need fixed length strings (NCHAR)? Using variable length strings (NVARHCAR) would most likely make it easier to handle the data and probably also save space since the string doesn't need to be padded with empty chars
- the question sounded like you're going to concatenate different information pieces into a single column. If this really is the case you should avoid that solution since it's going to cause problems sooner or later (typically sooner) and require more complex logic (using substrings, fixed lengths, possibly delimiters etc etc). If the requirement is given, perhaps it would still be reasonable to talk it over one more time. Of course if you don't have the possibility to modify the application itself, it's a different situation but based on your post I understood that modifications are possible.
Best regards.

well, I was using fixed length since this was my first app that I have built using asp or sql as this is my first job out of an associates degree. I originally set them because I am controlling the string length from the app itself. Its not really a concatenation of strings though. We have one table with store locations that were just a string of numbers such as 101. They now want it to show 101-City.
This is linked to another table through the information entered in the app. So the string itself is not changed dynamically by any users. it is set by a separate page of the app that is only assessable to the admin. Thanks for the post and I will definitely keep that information in mind on future endeavors as I am still learning and have a long way to go. It will also clear up that pesky white space in my dang columns.. lol
As you can probably guess I have not had much database training , just code(c++,Java etc..) I had to teach myself sql and asp so I'm sure it would give a professional a headache but it works and is improving with every day that passes. Thanks again for your assistance and I'm sure you will hear from me some more.

Yes, I understand. Just for the future use, if the code is the key to the city, you should have a lookup table for cities and fetch the name using a join. For example if the city name changes you'll now have to update part of the string field to correct the situation on every row.
At some point when you have time, have a look at W3Schools web site. There's lots of basic theory in clearly explained format. Even though it's mainly MySql, the theory is much the same. For example this could be interesting: http://w3schools.in/php-mysql.php?tutorial=Database-Normalization[^]
Good luck to the project

Hi all
I want to count records in a table respect to each date.
select count(id), add_date from packages group by add_date
this gives results only for dates which has exist.
Say I want to find the count in a range of dates, and if records not found then the count as zero.
Is it possible to do this with MySQL
I appreciate your help all the time...

Hi,
Perhaps the easiest way could be that you create a new table, for example SingleDate and add all necessary dates to that table. After that, using outer join, join the data between the date table and your table. So something like:
SELECT ...
FROM SingleDate d LEFT OUTER JOIN Packages p
ON d.Date = p.Add_Date
GROUP BY d.Date

Thanks for the comment.
Should I do with a temporary table or create a table in the database permanently? I've tried the following.
CREATE TEMPORARY TABLE date_col (add_dates nvarchar(50));
INSERT INTO date_col (add_dates) VALUES('2011-04-06');
SELECT * FROM date_col;
But stuck with two things.
1. How can I loop the date range and add all the dates into the table
2. I think to be in safe side I want to drop the table after the query required data, isn't it?
I appreciate your help all the time...

I would do it permanently since most likely this is not the only case when you need the dates.
To fill the table. Why not create a stored procedure. If you need to fill for a specific period again then you can use the same procedure. Something like:
CREATE PROCEDURE DateFill(d1 DATE, d2 DATE)
BEGIN
SET @d3 = d1;
REPEAT
INSERT INTO DateTable (date_co) VALUES (@d3);
SET @d3 = DATE_ADD(@d3, INTERVAL 1 DAY);
UNTIL @d3 > d2
END;
For dropping the table, I wouldn't since if the table is created and permanent you can continue to use it later. Just add a long enough date range to the table (say, 500 years )
Also it might be a good idea to add an index to the table to speed up the usage: http://dev.mysql.com/doc/refman/5.1/en/create-index.html[^]

Actually I don't want to keep records for a long time. Only for an instance.
The requirement is, for few sales rep I want to find the sales in a date range. That is for each sales rep I want to find the sales in a date range.
I appreciate your help all the time...

This is a different thing. What I'm saying is that consider populating the table with long enough date range. And when you use the table take only the relevant portion of dates from it using proper WHERE condition. For example:
SELECT ...
FROM DateTable dt LEFT OUTER JOIN MyTable mt
ON dt.DateColumn = mt.DateColumn
WHERE dt.DateColumn BETWEEN @startdate AND @enddate
This way you can reuse the same data every time you fetch data for a new date range without having to re-create the dates.
