An extended query field class that is being used to define a query expression for the SQL statement using the LEFT function. It inherits the QueryField object.

Below is a sample code on how to use this class.

var where = new LeftQueryField("Column", "Value");
var result = connection.Query<Entity>(where);

The result would contain all the records where the Column is starting with Value.

The GetString() method returns a command text that utilizes the LEFT function.

var where = new LeftQueryField("Column", "Value");
var text = where.GetString(connection.GetDbSetting()); // Returns (LEFT([Column]) = @Column)
