I don't know how to execute query statement in kentico. I used ExecuteQuery of ConnectionHelper to run stored procedure and success, but it can not run with query statement. Please help me soon. Thanks!

Also, have you looked into the following articles? Reason I ask is because there are a lot of other ways to access data through the API without having to create custom SQL database objects. I personally take advantage of page type queries. I'll create a query in there even if it is only SELECT * FROM External_Table1 WHERE ##WHERE## ORDER BY ##ORDERBY## or EXEC SP_Name param1. This way it leaves the code open for me to edit in the UI and access easily in code without having to change the C# code if the query changes

http://devnet.kentico.com/articles/kentico-8-technology-dataquery https://docs.kentico.com/display/K8/Working+with+database+queries+in+the+API

This code should get you going in the right direction:

QueryDataParameters parameters = new QueryDataParameters();
parameters.AddGuid("@ItemGuid", Guid);
GeneralConnection cn = ConnectionHelper.GetConnection();
QueryParameters qp = new QueryParameters("DELETE " + customTable.ClassTableName + " WHERE ItemGUID =    @ItemGuid", parameters, QueryTypeEnum.SQLQuery, false);

Thanks Charles. example: I want to run "select F1, F2, F3 from Table where ID = @id" so how do I execute this query by ConnectionHelper?

Hi all,

To Brenden's response I would add that it is recommended to use a ConnectionHelper class to run custom queries. In some cases its possible to have SQL deadlocks. To answer the initial question - to run a simple SQL query use this code:

DataSet ds = ConnectionHelper.ExecuteQuery("select * from CMS_User", null, QueryTypeEnum.SQLQuery);

Kind regards,

Richard Sustek
