dynamic-queries

i using the dynamic query to pass the variables select a.TableName, COUNT(a.columnvalue) as '+'count'+' from Settings a where a.ColumnValue in ('+ @columnvalue +') and a.Value in (' + @value +') the @columnvalues = 'a','b','c' @value ='comm(,)','con(:)' how to pass this in dynamic query any idea??? Jim B I would use the sp_executesql command. Some more documentation is here: http://msdn.microsoft.com/en-us/library/ms188001.aspx Basically, you define a sql query, and parameter list, and then pass those in along with your actual parameters into that method. So, something like this (real basic)

I am trying to create a query based on some JSON, I currently have the JSON parsed into a set of rules, each rule contains the name of the field, the type of comparison (=, > etc) and the value to compare. The issue I am having is getting it from that rule, to an IQueryable object, I am guessing I need to use reflection and somehow build the expression tree, but I'm not sure on the right approach... Assuming I have: public class Order : BaseEntity { public int OrderID{ get; set; } } and I have the rule which is: public class Rule { public string field { get; set; } public Operations op { get;

Is there something like JPA Specifications for Spring Data MongoDB Repositories? If not, how can I make dynamic queries with repositories? A classic scenario could be a search form with optional fields that the user will fill. I found myself a way. The trick can be done using QueryDSL , in the following way: First, add the QueryDSL dependencies: <dependency> <groupId>com.mysema.querydsl</groupId> <artifactId>querydsl-mongodb</artifactId> <version>${querydsl-mongo.version}</version> </dependency> <dependency> <groupId>com.mysema.querydsl</groupId> <artifactId>querydsl-apt</artifactId> <version>

I generate a dynamic query in My sql Stored procedure. I wanna get the result of this query into a out parameter. How to do this ? CREATE PROCEDURE 'searchInvoice' ( OUT numOfRecords INT ) BEGIN DECLARE query1 TEXT; DECLARE query2 TEXT; SET query1 = 'SELECT COUNT(*) bla bla bla.....'; // Query1 to select the count of matching tuples.. SET query2 = 'SELECT * from bla bla bla....'; // Query2 to select original records... // later part of this both queries generate dynamically according to some IN parameters.. // now I wanna assign the output of the query1 into numOfRecords // and I wanna execute
