Storing And Searching A Field
Dec 2, 2003
I need to find a better way to find all parts from a particular category. Each part can appear in multiple categories.
Currently, I use the id of a catagory and search the txtCatagory field in the position of the id.
I have included the query string for you to see.
SELECT * FROM tblParts
WHERE SUBSTRING(txtCategory,@CatId, 1) = '1'
ORDER BY PartNum ASC
txtCategory is Data Type Text
This currently does work, however is causing some performance problems with my ISP.
Any help would be greatly appreciated.

Hi all,
I have a very big database with me. This database has large number of tables and each table has n number of fields.
My trouble now is that I desire to search for a field name called 'empname'. Is there any query possible for me to search all tables and return me the table names which contain fields which match with 'empname'. Adding essence to the porridge I would like to know if I specify something like '%pnam%' it should match any field name which contains 'pnam' as a portion of its name. Is all these possible ??
Thanx for any help in advance,
Regards,
tvks

Im building up a query in my code behind. When I execute this query it returns a list of users who match the criteria.BUT, I want to add something extra. In my DB in the tblUserData there's a field "interests" datatype nvarchar(30) which contains the numbers (comma-delimited) of the interestsID in my tblInterests. For example, my interestsfield may contain something like: 1,4,8Now if someone wants to find someone who has number 4 and 8 as interests, how can I search in this textfield?!?I wrote this in a SP, but I'd really like it to be possible from code-behind and build the query myself...declare @s varchar(20)set @s='4,8'EXEC('SELECT * FROM tblUserData WHERE Interests in ('+@s+')')

I'm using the .NET Framework 1.1 together with SQL Server 2005 Beta.
I have a search page where you can search a db using a number of fields or combination thereof. Three are text fields (patient id, surname, forename) and I can do any search using one criteria or any combination without any problem.
However, I'd also like to search on a dob (datetime field in SQL Server) and I'm having real problems in making this work. The dates are stored in the following way in SQL Server: '1938-05-31 00:00:00.000', whilst they are displayed as 'dd/mm/yyyy' on a web page, which I guess corresponds to my regional settings.
My code is shown below. I 've tried any number of combinations for the dob string with no success. I do not get any error, just no records are returned.
Does anyone have any idea what I'm doing wrong and how to correct it before this drives me crazy?!
TIA for any help.
P.S. chxPatID, chxSurname etc are all checkboxes.
<code starts>
If chxPatID.Checked Then
strSQL = strSQL & " patid= '" & txtPatID.Text & "' "
strAND = " AND "
End If
If chxSurname.Checked Then
strSQL = strSQL & strAND & " surname ='" & txtSurname.Text & "' "
strAND = " AND "
End If
If chxForename.Checked Then
strSQL = strSQL & strAND & " forename='" & txtForename.Text & "' "
strAND = " AND "
End If
If chxDoB.Checked Then
strSQL = strSQL & strAND & " dob= " & CDate(Year(txtDoB.Text) & "-" & Month(txtDoB.Text) & "-" & Day(txtDoB.Text)) & ""
End If
</code ends>

I have a varchar column which containd comma delimited values like
Rec# Fruits
1 Apple, Peach, Strawberry
2 Orange, Mango
3 Banana, Grape
...........
Now i have to add search facility so that a user could search for more than 1 fruit at a time. I have a Stored Procedure which returns records from this table. that SP has a Parameter @SearchFruit Varchar(500) and the user could pass in values like 'Apple, Mango' to this parameter.
Now how should i write the SQL so that i get back the records Rec# 1 & 2 since apple is there in 1st record and mango is there in the 2nd ??
I know if a put the comma delimited values as individual records in a temporary table and also do the same for the parameter values then i can get the desired results. But i want to avoid doing that. Any other way ?
Thanks
Sumit.

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

I am trying to run a like statement that has a datetime column and for some reason it does not return any values. I looked in the SQL help files and in states in there that when trying to select using a datetime that the preferred way of doing it is using a like statment. Does anybody know a better way of doing this? Here is my example: (I have dates in this column ie 2006-02-13 11:30:54.220)
SELECT * FROM workorderhistory WHERE wheninstalled LIKE '%2006-02%'

I am doing a search on a column of type varchar, the columns all contain dates in the future. When i perform a query
SELECT [CIFPan]
,[CIFMemNum]
,[CIFLName]
,[CIFFName]
,[CIFExpDate]
FROM [FutureSoft].[dbo].[zCIFRecord]
WHERE CAST([CIFExpDate] AS smalldatetime) between '12/01/2000' and '01/30/2015'
I get error:
Msg 295, Level 16, State 3, Line 1
Conversion failed when converting character string to smalldatetime data type.
I can use this same query on an exactly same other field that contains dates in the past. Is there some kind of limitation on the dates as far as them being in the future or past?

Hello there,I just want to ask if storing data in dbase is much better than storing it in the file system? Because for one, i am currenlty developing my thesis which uploads a blob.doc file to a web server (currently i'm using the localhost of ASP.NET) then retrieves it from the local hostAlso i want to know if im right at this, the localhost of ASP.NET is the same as the one of a natural web server on the net? Because i'm just thinking of uploading and downloading the files from a web server. Although our thesis defense didn't require us to really upload it on the net, we were advised to use a localhost on our PC's. I'll be just using my local server Is it ok to just use a web server for storing files than a database?

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.

Let say a user wants to search for the name Joe Soap
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 ?

For example, I have a complete statement with CREATE PROCEDURE and all code in my query window.
Now I want to run/deploy this code to many servers at once.
Instead of having to reconnect to all server (5), I want an add-in which have checkboxes for me to select.

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'm making a web page for a clinic.it needs to be able to search for patients by first name, surname, date of birth and patient number.i'm using visual web developer and i have my database, my data source and GridView grid.i want 4 text boxes for my first name, surname etc. when u click enter on any of them i want to retrieve all their data and display it in the gridview.at the moment i have one text box on the web page and through the "Configure data source" option on the grid view i can retrieve the specified data but for only this one item, e.g. SELECT * FROM [Patients] WHERE ([DOB] = @DOB). if i add another text box to my web page, and don't do anything to it, the query wont run. if i add and "AND" statement to the query, e.g. SELECT * FROM [Patients] WHERE (([DOB] = @DOB) AND ([FirstName] = @FirstName)), again it won'r run or return and data. any ideas on what i can do or where i'm going wrong. thanks

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?
