Qwiq does not support variables in queries

[rjmurillo]

You can use variables in queries to pass user input or calculated values. To create a query that includes variables, create placeholders in the query string using @variable, where "variable" is the name of the variable. Then pass the name (less the "@") and value of each into a dictionary as shown.

// Define a query that uses a variable for the type of work item. 
string queryString = "Select [State], [Title] From WorkItems Where [Work Item Type] = @Type";

// Set up a dictionary to pass "User Story" as the value of the type variable.
Dictionary<string, string> variables = new Dictionary<string, string>();
variables.Add("Type", "User Story");

// Create and run the query.
Query query = new Query(workItemStore, queryString, variables); 
WorkItemCollection results = query.RunQuery();
