DataSource Controls :: Search Table Column For Substring / Individual Tags
Jan 27, 2010
I have an SQL table which looks similar to the following:
Title | Author | Tags
'title1' 'author1' 'horror, steven king, clowns'
'title2' 'author2' 'childrens, roald dahl, chocolate'
Let's say I wanted to find the name of a book that has the tag 'clowns' in it...how can I do this? 'clowns' is a substring of the tag for 'title1'...but how do I search for substrings? I have tried to use the "LIKE" keyword but obviously it doesn't work in this situation.

I need to pull a SubString from a Linq Datasource, but can't use INTs per .SubString(int, int) I have strings such as xxxx.xxxx.xxxxx.AAAA.xxxx.xxxx.xxxx.xxx and I need to pull AAAA out. the preceeding x's will be varying lengths, so I can't use a static int. What I do know is that there will be a static number of periods (.) leading up to the AAAA. I can't figure out how to use the SubSting with characters rather than indexs. This is what I have so far:

I'm assuming I need to use a pivot table from what I've found so far. However, every one that I've seen has not had the date setup like I have.
I have a Gridview on my page which I need to be populated like so
Date NCMR
1/1/10-1/31/10 #
2/1/10-2/28/10 #
I want to do this for 10 months... bottom record being the current month (or last month). I would also like the Date to format to January 2010 I used the above date format because that is how it is in the table. Basically, I need to know how to create the pivot table to search the table for 1/*/10, 2/*/10, etc

I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.
The current code:
[Code]....
Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?

I am trying to create a smart search for a specific column in a database. the column is a short text (title of an article), so I am looking for a search that will ignores the order of the words, and mispelling mistakes. the search must returns the search results order by rellevance, and the seach is not in english, so the FREETEXT that search by meanning won't work here.
I created already a search SQL, but it is not wide range enough and won't except mispelling.
[Code]....
Even if there is a ready to use tool that doing so, it can be helpfull, although I am not sure that for such a simple text a tool is requiered.

BY the way, I am using SQL Server 2005 with asp.net application.

I'm trying to build an asp.net page using c# that will query a column in an Oracle database that has 20,000 rows. I want to display all rows that match this regular expression pattern "[]$".(should only have about 5 rows that match this pattern) The version of Oracle we use does not support regex so I need to find a way to do this in c# but I'm not sure how do that.

However has anyone ever seen a situation where, when you try to access the value of a column in a DataRow, you get the error "Column... does not belong to table.." when, in fact, it does?
The column name in question is called "ByWeight". I am wondering if either that, or maybe one of my other column names, is a reserved keyword and that's causing/masking this error.
If I look in the locals window and expand the DataRow, one of my columns is DBNull - by that I don't mean that the column value is DBNull, I mean the actual column itself is DBNull so it doesn't expand. I think there's a clue there.

I can easily create a search that will allow a user to input a single word (or a portion of a single word) into a text box that will search a database column.
But what I want is for the user to be able to type two or three words into the textbox and produce results where just one of the words have to match the contents of the columns cell.
I don't need to be able to do a multi column or table search, and I'm using C# and MS Access.
I imagine this question would have been asked more than a couple of times - but I can't find a decent answer.

I am able to store the current time of day in a column defined as time with the C# code as:notestable.NoteTime = DateTime.Now.TimeOfDay;The hour, minutes, seconds, and even millionth of a second is stored. But now, I need to retrieve the time and convert it into a string. I tried to use DateTime statements to accomplish this as with:
DateTime nt = notestable.NoteTime;
String FirstT = nt.Hour.ToString() + ":" + nt.Minute.ToString().PadLeft(2, '0');
Regarding the 'nt' variable, I got an error message that said: Cannot implicitly convert type 'System.TimeSpan?' to 'System.DateTime'.Regarding the 'Hour' designation, I changed the definition of 'nt' to 'var' and got an error message that said: System.Nullible<System.TimeSpan>' does not contain a definition for 'Hour' and no extension method could be found.So, how do I access the time from a table and convert it into a string for display in a TextBox?

I have defined some binary bit columns in an SQL database table to indicate yes/no conditions, but I don't know how to set or reset them. I tried to use "profile.Volunteer = 0;" C# code in an event handler to reset a voluntary state for the Profile table of members, but what I got back was an error message that said, "Constant value '0' cannot be converted to a bool'. So, if a '0' cannot be used to reset a boolean value, what can be used?

I attempted to change a table columns data type and in the process caused a lot of issues. I had a date column in one of my tables and stupidly changed it from varchar to date. When I tried to run queries on it I keep getting the 'cant find column 3 error'. Now that tables structure is :
[Code]...
So column 4 is actually the date column. All other queries work for this table. I then tried to change it back and then copied all data to a new table and now I am using the new table and converting the dates as needed but I am still getting the error.
SELECT * FROM postlinks WHERE postlinks.date >= CONVERT(datetime,CONVERT(varchar(10),GetDate(),112))
