I'm trying to "move" a LinqDataSource control to code behind to better control the query parameters. Problem I'm having is how does the "It" keyword translate to Linq To SQL syntax (not sure if I'm getting the terminology right here, but I think you get my meaning).
Control Markup:
[Code]....
Query:
[Code]....
Is yield keyword is Statement keyword or Contextual Keyword?
Because in MSDN yield keyword is mentioned in both type of Keywords so i'm little bit confused in this.
In one of my column have a comma separated list of keywords.I have to build a query that will return the matching rows whenever user enters the keyword.for ex.if my keywords are java,.net,sql,php,ajax then on search of java OR java,sql OR php,java should return the above row.
View 5 RepliesI have a search screen where there are total 15 search fileds...one among them is amount range (money datatype)...using Between keyword i am trying to filter the search results...problem is it is taking more time to fetch the records...if i comment only money range in where condition and all other remain same..then it is returning in 2 seconds for 25 records...otherwise it is taking around 31 seconds to return 25 records..
