I design table which has column "keywords" for keep keywords seperated by comma (,). If user pass one keyword, how can I know that the keyword user select is exactly match with any keyword in field. I mean I just want SQL return only rows that user's keyword is exactly match with at least one keyword in "keywords" column.
Ex.
PK1 Data1 Data2 keywords
1 1 1 apple, orange
2 2 2 mange, orange
3 3 3 mange, apple
If user select keyword 'orange', SQL must return only row 1 and 2.
Can anyone tell me how to search an SQL database for a given key word in a textbox? I basically have a database that has a qualifications column and this column needs to be searched for the data given in the textbox. Which is the best method to search for the data? Is it a simple SQL query or an XML based search engine type? Can anyone give any suggestions regarding this? If XML is efficient then how do I use it to query my database, as I'm pretty new in XML based searching.Thanks

I'm trying to make this piece of code work, I get all of it except how I get the data from the database, what I wish to do is. On page load I wish to take the value of a querystring in the page URL called ProductID and search a database to see if it exists in a specifical table and column, if it exists I wish to make a button not visible. the code I am using is:
#############
protected void Page_Load(object sender, EventArgs e) { // Get the querystring value String inQueryString = Request.QueryString["ProductID"];
// Get the data from the database, using the above value DataTable data = ??
The datasource I want to connect to is SqlDataSource1, and the table I want to search is “Reviews�. I want to search in the column “ProductID� and search for the ProductID from the URL query string above.
// Did we find a product in the database? if (data != null && data.Rows.count > 0) { // Code to display the product's information // We found a product, so we need to hide a button Button5.Visible = false; }
}

Hello I have a Database which contains like 1000 Tables. I am not the designer of that DB.So I need to in which table and which column that string exists. IS there a DBWIDE String search possible? Thanks and Regards
I have a huge problem that ive been sitting with for awhile.
I have a web page with 4 dropdownlist boxes on it
Gender: Race: Field: Location:
Now a user can search a SQL db from selecting values from these 4 dropdownlist boxes which are equal to values in the db obviously.
when they have done that and pressed submit a Gridview is populated with the people corresponding details and the user is able to view each row seperately.
Now the problem i am having is that when i havent used all 4 selections for eg
Gender: null (no value selected) Race: Black Field: Accounting Location: Los Angeles
then no information is returned from the db in the gridview. im using a sqldatasource to populate the gridview and here is the query string that i am using :
Code:
sql SELECT [title], [gender], [initials], [name], [surname], [birthdate], [postaladdress], [suburb], [city], [zipcode], [criminalrecord], [drivers], [maritalstatus], [dependants], [citizenship], [province], [contactref], [hometel], [cell], [jobtitle], [relocate], [emmigrate], [email], [worktel], [enddate], [startdate], [FIELD], [education], [company], [positionheld], [jobdescription], [contactperson], [contacttel], [startdate2], [contactperson3], [jobdescription3], [positionheld3], [company3], [enddate3], [startdate3], [contacttel3], [other] FROM [cvinformation] WHERE (([race] = CASE WHEN @race IS NOT NULL THEN @race ELSE [race] END) AND ([province] = CASE WHEN @province IS NOT NULL THEN @province ELSE [province] END) AND ([education] = CASE WHEN @education IS NOT NULL THEN @education ELSE [education] END))
what i want to do is whether the user doesnt choose any selection and leaves the choice null that ALL the information in the table of the db be shown and even if they only choose 2 values and leave the others null then it still brings back the information from the criteria chosen..

Hi I was wondering if anyone can help me out here. I want to search a word in the database which has more than 80 tables is it possible to search all the tables at once for that word.
Yep, I know this will have been asked before (because I've seen it), but I can't for the life of me find a thread!
So I've inherited this database and I need to search the whole darn thing for a single word, returning something lovely, like the table or column the thing resides in. Basically it's a code in one of 100+ code tables, all with inconsistant, unclear naming - YAY!
FYI, I'm using SQL Server 200 and the word I'm looking for is "Unpaid".
Hi,I would like to use keywords inside a record to search for - like asearchengine.How can I design the table? Right now I would store data in Memo-Column in aformat like ";apple;banana;lemon;". I would use a INSTR(ring)-function - butI wonder if the performance is still OK then - even when I index the field.Are there maybe even better ways?Thanx in advance.Greg

Does anyone know how i go about writing a search query using paramaters, ive been using this as my template: Select Distinct Recipedata.Name, Ingredients.Ingredient, Directions.Directions from Recipedata,Ingredients,Directions Where Ingredients.Ingredient Like '%Chicken%' and
RecipeData.RecipeID = Ingredients.RecipeID and Ingredients.RecipeID = Directions.RecipeID;
Problem is now that i want to use paramters instead of hard coded values as this is for a user. How do i go about this? This database has a VB2k5 front end for the desktop and PDA(and no the target PDA is not web enabled so web servcies arent available to me).
I want to search for a keyword in the database. The database has approximately 30 tables and the amount of data in tables is very large. Most of the tables hold 25000 rows. The search procedure for searching a keyword that i want to use is as below. When i executed the stored proc it took 20 minutes. What i want to know is full-text search a better option than this or is there any other way out.
I'm trying to find some attributes within a database I'm working with. I'm working with SQL Server 2000, and I'm trying to find table which have a certain attribute in them. for example, If I want to see tables from my database which have an attribute called 'home_address', what would the query be? Or is there an inbuilt function in SQL Server 2000 which allows me to search this?
Hi,I would like to have a full-text search from a sql server database in my aspx page. I have tried to do it by creating a Dataset with a DataTable where there is a query like: SELECT title, yearFROM ProjectsWHERE title like N'%@Search%' Problem is with the like operator - the visual studio does not reconize the @Search as a parameter, as it reconnizes it in the query below (which works fine by the way): SELECT Projects.*, theme AS Expr1FROM ProjectsWHERE (theme = @theme) Can anybody help me how to deal with this problem, which is the best way to have a full text search? Cheers, ArtoV

I have a search form in an ASP.NET/VB page. The form has the input text box and the button "search". The keywords are passed in the URL to results.aspx.
Here is an example of what I get in the URL, when I write the keywords "asp", "book" and "london" in the input text box and click "search": results.aspx?search=asp%20book%20london
The database table has 3 fields: "id", "title" and "description".
I want to display all the records where at least one of the keywords is found in any of the 2 fields "title" and "description".
1. I suppose I need to get the words out of the URL to be used by SQL. Maybe: string[] searchString = request.queryString("search").split('search'); ??? How can i make this run when page loads? I supose i need it. Right?
2. How should the SQL look? I supose i need to use the "Like" command SELECT * FROM books WHERE title LIKE ... But how to I use it if I can have 1, 2, 3, ... keywords?
im pretty new to SQL and i'm just reading up on full-text searches... i need to do a a full-text search on one table i have in the database.. however I'm reading about full-text indexing/searching and a lot of pages are saying that it uses a lot of resources when searching.. i was wondering how bad is it really? we have about ~100 users who would access the database, probably the peak would be 75 at a time.. would people using a full-text searching slow it down a lot? the servr is a dell poweredge 1750 server, dual 2.8ghz xeon, 1 gig ram.. and also, about the incermental population, if i read right, it populates the catalog each time a item in the table is deleted/inserted/modified.. so would that use a lot of resources as well?
i'm just trying to see if it's worth it to enable full-text indexing for searches on the database if it doesn't slow down the server too much... or are there any better/easier ways to perform searches?
I am currently seaching a db for all tables that have the same column name, for example, 'qdate'. Can anyone let me know how I can write a script that will search a db for all tables with this column name 'qdate'?
