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 ??
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
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 ?
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 have the time of an event stored on each record as a datetime field.Itincludes the year,month,day, etc. Suppose my user wants to search the tablefor all events over the lunch hour, say between11am and 1pm. How do Iconstruct the SELECT query to peek into each datetime field and return onlythose records that satify the specified time range?Many thanks.
I have a customer who wants to SELECT records based on a partial match in atext field. For example, in a list of telephone numbers they want to searchfor all records that contain the digits '777' in any part of the string. Howdo I formulate such a query?Many thanks.
We have a application running on Sql server 2005, which require to browse/search text field. Does anyone know if Sql server's search/browse performance on text field is better than oracle?
The table the application will search on is a customer table that has a 10000 records in it, does this size of table casue a performance problem for sql server 2005 if I index the text field?
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?
I am using an image datatype to store multiple filetypes includeing plaintext data. it works except for pdf Data. When I retrieve the the filecouldn't be opened in acrobat reader and the file was 3KB bigger than theoriginal.Any suggestions would be helpful.
I have a very large array of floating point numbers which I am tryingtostore in an image type field. I am using the dataset class todirectly enter the data but am having trouble trying to get this typeinto the image field. I guess the question is how do I get a largefloating point array into an image (byte)field of a database using thedataset class for new row entry.Thanks
I am storing xml in an xml datatype field in a table. But when I am generating physical file from the xml field, '&' in the xml field is getting converted into '&' in the physical file. But I want '&' to be intact.
i need to store a bmp or zipped file in a field of a ms sql db. i read the file using vb6 o.net, and in my mind i think sto store it in binary mode. the files could be more of 12 mega. whitch kind of field a could use?
This may be a stupid question but I can't find an easy answer for what Iwant to do. I need a blob data field that can store both binary and textdata like the sql_variant field. I am using vb.net to populate a sql table.I want to store both string and binary data.
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?
I am trying to find all the email addresses with a " ._" I use '%._%' but it returns all records. What is the correct syntax? Also, is there a way to search for a field where the underscore is followed by a single alpha letter and then another underscore? like bla_A_bla or bla_Z_bla.thanksMilton SELECT DISTINCT fname, lname, inet FROM ocadbo.notes where inet like '%._%'
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.
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'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?
