Searching Database Through Asp.net
Oct 12, 2007
OK I have a search page and the query that is being send from the search box is
"SELECT * FROM [problems] WHERE ((problemBody LIKE '%' + @search_id + '%')OR @search_id IS NULL)"
Now say I have in the column for problemBody "Search the database" If i Type in the search field search the, or the database, or data, ot search, or even just s it will bring back records, But if I do not use exact keywords such as "search database" it will not bring back anything. How do I make it search all the keywords used?? like a normal search engine.
Thanks

Hi,
This is the first database I have ever created, so please bear with me.
I've created a simple database with 1 column and about 80,000 rows. In each row is a word (basically a dictionary without definitions).
I have written a query which works, and is, as follows (you'll notice that i'm not the most original of people)
SELECT
word
FROM dbo.words
WHERE word= 'hello'
This finds the word hello.
In excel I have a row with 25 letters and then a column with every single combination of letters from 3 to 10 lettered words. (It makes sense to me!)
This comes back with a lot of possibilities (thousands), but is great in the sense that when I change any of the 25 letters the entire column automatically updates.
What I am trying to do is then take all of these possibilities and compare them against the dictionary.
I have written a line in excel which automatically creates a cell a bit like this, for the first couple of thousand possibilities:
WHERE word= 'abc' or word= 'fgm' or word= 'klm' or word= 'pqr' or word= 'uvw' or word= 'bcd' or word= 'ghi' or word= 'lmn' or word= 'qrs' or word= 'vwx'
I then whack this into the query from above and off it goes. The only problem is that the search takes ages, and because of limitations in excel I can't put more than a thousand or so words in the cell.
I am certain there is a faster way of searching through all the possibilities, any help would be much appreciated.
Thanks in advance

Im trying to do a database query based on user input from a text field. I pulled apart the string that was
entered into the search form and stored it in textArray. The problem I
am having is when I include commmon words such as the, near, view and so
on into the search field I end up with zero results. when I only search
for less common words such as rocky and argentina for example the search
works fine. at first I thought that maybe it was generating too many
results and was screwing up but when i search for rocky it works and
when i search for near rocky it doesnt.
I realize the code might not be the most efficient but here it is...
@searches_pages, @searches = paginate(:searches, :per_page => 10,
:conditions => getSearch(textArray,params[:country]))
def getSearch(textArray,selectedCountry )
result = []
string = ""
if selectedCountry != "Optional Field"
string << "country = (?) and "
end
textArray.each do |x|
if textArray[textArray.length - 1] == x
string << "match(country,caption, keywords, notes) against
(?) "
else
string << "match(country, caption, keywords, notes) against
(?) and "
end
end
result << string
if selectedCountry != "Optional Field"
result << selectedCountry
end
textArray.each do |x|
result << x
end
result
end
Im not sure if i supplied enough information but I am trying to finish
this project soon so any type of responses would help. Also, if there
is an easier way to do an sql search based off of what is entered into
the search field please let me know. The reason I did this is because I
wasn't sure how many words the user would be entering into the field.
And without knowing this I could not hard code the conditions => so I
wrote a helper method.

I am finishing up my senior project application but I wanted to include a search function that would search all the tables of the database and look for matching text that is input by the user. I am not really looking for code or anything just some pointers in the right direction. I was thinking that I would have to create a view that is populated by a sub-query. My problem is how do I output the results of a search of every relevent table in the database when they all have very different column names and data types? Im guessing column aliases are involved somehow but I am not really sure where I should start. Any suggestions would be appreciated.

I've been given read access to a database and I also am looking at a GUI which draws data from the database. I am trying to map the results I see from the GUI to find the columns that the data is in... So.. big database, takes a long time to search the entire thing so I try to narrow it down by the following:
Code:
select * from information_schema.columns where table_schema = 'db19' and table_catalog = 'masterdb' and
table_name in(select table_name from information_schema.tables where table_type = 'base table' and table_catalog = 'masterdb' and table_schema = 'db19' and data_type in ('text' and 'varchar'))
This essentially gives me a list of tables and columns whos data type is either text or varchar. Once I have this list... I then run the following on each:
Code:
select top 1 [col_name] from [table_name] where [col_name] like ' (here is the value I want to search) '
So this runs through each table, looking to see if a value exists and if so, prints the result.
I am then left with a much much smaller list that I can manually look through and find the one I am looking to specifically find.
Is it possible to do this running only one query... where the output gives me all the columns in with a specific data type that contain a value I enter Anything else to make this more efficient
I am aware that there are data mining programs that could probably do this however I only have read access on the database which often causes a problem. The application I am using is "Aqua Data Studio" ....

Hi, this is my first post on these forums, so please excuse me if this topic has already been covered.
I'm currently working in a power station for student vacation work placement. I need to export data from a database that gets it's data from machinery and inputs out in the plant. The machines that provide this input put it into a database, and I need to find the relevant data to export.
My problem is that, in some cases, the sample data that i'm given may be under different field names, in a completely unrelated table. I was looking for a way to search the entire database (250+ tables) for a certain string, so I can find where it is in the database, and run queries on the table it originates from. For example:
My sample data shows me that I have an object with the ID Y03A3DEA_TH1. I know this ID will occur somewhere else in the database, but i'm just not sure where.
If anyone knows of any way that I can search the entire database for specific data, either using tools in MS SQL 2000, or 3rd party apps, i would greatly appreciate their help.
Thanks a lot,
Jack Smith

Hi,
I am building a website in ASP.net C# for a university project, and would like to search a table (Member) for a field (UserName) using a session variable Session["sUserName"]. If that field is null, then I would like to insert that session variable into the field to start to create a new user. However, I am getting errors saying that I am using invalid expression terms. My code is;
//Create the Command, passing in the SQL statement and the ConnectionString queryString = "SELECT UserName FROM Member WHERE (UserName = @myUsername); ";
SqlCommand cmd = new SqlCommand(queryString, sqlConn);cmd.Parameters.Add(new SqlParameter("@myUsername", Convert.ToString(Session["sUserName"])));
//If UserName is null, display confirmation, else display errorif (UserName == null) ;
{UserNameCheckLabel.Text = "Username okay";
String queryString = "INSERT INTO Member (UserName) VALUES(@myUsername); ";SqlCommand cmd = new SqlCommand(queryString, sqlConn); cmd.Parameters.Add(new SqlParameter("@myUsername", Convert.ToString(Session["sUserName"])));
}else;
{UserNameCheckLabel.Text = "That username is in use";
}
I have a feeling I should be checking the database for the UserName, but I'm not sure whether to put this in the SELECT statement part or as a method... I would be most grateful for any advice!
Many thanks,
Chima

Hi!
I found a problem while retrieving/searching/filtering Myanmar Text with a Select Statement, In a Myanmar Text table there in a column called HeadWords.
It's Sample Data
HWID,HeadWords
1,|က|
2,|ကာ|
3,|ကိ|
4,|ကီ|
5,|ကဲ|
I want to make the following search:
SELECT * FROM TableName WHERE HeadWords LIKE '%|က|%' this should give me all entries that have a "|က|" *ANY* place in the HeadWords column. Right?
However, it gives me unproper results. you may see last two records have 2 characters between pipe(|).
HWID,HeadWords
1,|က|
3,|ကိ|
5,|ကဲ|
Since the wildcard character % means no or all characters it should work. And I've tried pipe, comma, forward slash and back slash.
The problem only seems to occur when the wildcard character is used for the any part of character. Let me know alternative way to search that matters. I've tried in MSAccess. There are same problem like MSSQL.
It's any problem in searching support for National Characters (UTF8). I've tried in OpenOffice Database with those data.
It's work fine.
If you not see Myanmar characters, please download fonts from http://www.fontmm.com/font_downloads.htm
Does anybody have an explanation to this, please let me know.
Thanks in advance!

Database design is well covered in undergrad CS. But does anyone know ofa textbook that deals with the design of database servers (and probablytouches on databases themselves), and perhaps deals with interpreting SQLinquiries?The motivation for this is that I wish to write a database server for aproprietaryoperating system (it resembles POSIX, but is not completely compliant)for an embedded processor system that exchanges queries from clients alsoemploying embedded processors. Stored data is all in one place.I'm a little familiar with the MySQL source code, but I don'twish to replicate something that complex. The sort of investmentI'm talking about should involve no more than three man, er, person-monthsby an experienced C++ programmer with plenty of experience in systemsand database programming for both Microsoft and Linux platforms.

Dear ASP.NET
How can I find records that contain a STRING from some (more than one) other fields ?
for example, I have:
Name_First = "aaa"
Name_Middle = "bbb"
Name_Last = "ccc"
Key_Words = "aaa,bbb,ccc"
(includes all values - comma separated)
How can I do the SELECT so that when I search for "bbb" on Key_Words I will get my record ?
Should I use "LIKE %aaa%" or something like this ?
(should I keep the comma separators ?)
Thanks in advance, Yovav.

I have two column's in my table, firstname and lastname
So if I do:
Code:
SELECT firstname, lastname FROM table WHERE firstname LIKE '%Joe Soap%' OR lastname LIKE '%Joe Soap%'
it returns nothing! So do I have to split the string Joe Soap or something ?

my app use a registration table
StudReg
(
stName varchar(30),
stDOB smalldatetime,
stGuardianName varchar(30),
stRegDt smalldatetime,
stRegNo bigint,
courseId smallint
)
the application registers the student details to a course.
each student gets a new registration no during registration.
the app should identify repeaters to a particular course by checking another
table RegHistory, which stores the details of student registrations for the previous 5 years.
RegHistory
(
stName varchar(30),
stDOB smalldatetime,
stGuardianName varchar(30),
stPrevRegDt smalldatetime,
stPrevRegNo bigint,
courseId smallint
)
the application must search the RegHistory table and list out those students who are the repeaters.
the sample entries in the two tables are as follows
StudReg
stName stDOB stGuardianName stRegDt stRegNo courseid
-------------------------------------------------------------------------
abc 01/01/1979 def 20/11/2004 12345 1
def 01/01/1976 xyz 20/11/2004 12346 1
... ..... ... ...... .... ...
mno 24/18/1976 pqr 20/11/2004 12400 1
RegHistory
stName stDOB stGuardianName stPrevRegDt stPrevRegNo courseId
abc 01/01/1979 def 20/11/2001 2345 1
ghi 01/01/1976 xyz 20/11/2001 2346 1
... ..... ... ...... .... ...
dfg 24/18/1976 pqr 20/11/2001 2400 1
to determine whether a student is a repeater or not, we have to search for an exact match in RegHistory table (where the student name, guardian name and date of birth in both tables match with the corresponding entries in Registration table).
here is my question,
if there are 100,000 students registering in each academic year, we will have
500,000 records in RegHistory Table and 100,000 records in studReg table
if i start searching for a repeater, i guess i will have to loop through all records in studReg, for an exact match in RegHistory, which wil be a time consuming process.
is there any other options to search for repeaters ?

Hi,I have come to point in my db design where I'm trying to figure whichis the best approach in making it generic (does this really matter?!?)Senario - I have a table called JOBS and this table contains fieldsuch as JobTitle, JobDescription, Salary etcI want to add to this table other attributes which are specific to acertain Job Industries.Solution - Add a join table for each type of industry containingattributes (db is now not generic) OR add a new table with a IndustryType field and a XML field containing the industry specificattributes.If I go the XML way will this just make it complex and slow to query?If not, what is the best way to query an XML field?Thanks,Jack

I have a table
GO
CREATE TABLE [dbo].[Speech] ( [SpeechId] [int] IDENTITY(1,1) NOT NULL CONSTRAINT PkSpeech_SpeechId PRIMARY KEY, [UniqueName] [varchar](52) NOT NULL, [NativeName] [nvarchar](52) NOT NULL, [Place] [nvarchar](52) NOT NULL, [Type] [smallint] NOT NULL, [LanguageId] [char](2) NOT NULL CONSTRAINT FkSpeech_LanguageId FOREIGN KEY (LanguageId) REFERENCES Language(LanguageId) ON UPDATE CASCADE ON DELETE CASCADE, [SpeakerId] [int] NOT NULL CONSTRAINT FkSpeech_SpeakerId FOREIGN KEY (SpeakerId) REFERENCES Speaker(SpeakerId) ON DELETE CASCADE, [IsFavorite] [bit] NOT NULL, [IsVisible] [bit] NOT NULL, [CreatedDate] [datetime] NOT NULL DEFAULT GETDATE(), [ModifiedDate] [datetime] NULL )
Now I want to search the Table Speech
Sometimes by : SpeechIdSometimes by : SpeakerIdSometimes by : LanguageIdSometimes by : SpeechId And LanguageIdSometimes by : SpeakerId And LanguageId
All can have conditions with IsVisible, IsFavorite and Type columns.
for example
I need all Speeches withany particular SpeakerId and LanguageIdwith IsVisible equals to trueand IsFvaorite No Matterand Type equals to Audio
For these type of queries I think the solution is
GO
CREATE PROCEDURE [dbo].[sprocGetSpeech]
@speechId int = NULL, @uniqueName varchar(52) = NULL, @nativeName nvarchar(52) = NULL, @place nvarchar(52) = NULL, @type smallint = NULL, @languageId char(2) = NULL, @speakerId int = NULL, @isFavorite bit = NULL, @isVisible bit = NULL
AS
SELECT SpeechId, UniqueName, NativeName, Place, Type, LanguageId, SpeakerId, IsFavorite, IsVisible, CreatedDate, ModifiedDate FROM Speech WHERE SpeechId = @speechId AND UniqueName = CASE WHEN @uniqueName IS NULL THEN [UniqueName] ELSE @uniqueName END AND NativeName = CASE WHEN @nativeName IS NULL THEN [NativeName] ELSE @NativeName END AND Place = CASE WHEN @place IS NULL THEN [Place] ELSE @place END AND Type = CASE WHEN @type IS NULL THEN [Type] ELSE @type END AND LanguageId = CASE WHEN @languageId IS NULL THEN [LanguageId] ELSE @languageId END AND SpeakerId = CASE WHEN @speakerId IS NULL THEN [SpeakerId] ELSE @speakerId END AND IsFavorite = CASE WHEN @isFavorite IS NULL THEN [IsFavorite] ELSE @isFavorite END AND IsVisible = CASE WHEN @isVisible IS NULL THEN [IsVisible] ELSE @isVisible END
Can anyone tell me?
Is it right way to do?Do you have any better solution?If my solution is better then Is there any performance loss with that query?
