示例1: CreateDefiningQuery
// internal for testing
internal static string CreateDefiningQuery(EntitySet entitySet, MetadataWorkspace workspace, DbProviderServices providerServices)
{
Debug.Assert(entitySet != null, "entitySet != null");
Debug.Assert(workspace != null, "workspace != null");
Debug.Assert(providerServices != null, "providerServices != null");
var inputBinding = entitySet.Scan().BindAs(entitySet.Name);
var projectList = new List<KeyValuePair<string, DbExpression>>(entitySet.ElementType.Members.Count);
foreach (var member in entitySet.ElementType.Members)
{
Debug.Assert(member.BuiltInTypeKind == BuiltInTypeKind.EdmProperty, "Every member must be a edmproperty");
var propertyInfo = (EdmProperty)member;
projectList.Add(
new KeyValuePair<string, DbExpression>(
member.Name,
inputBinding.Variable.Property(propertyInfo)));
}
var query = inputBinding.Project(DbExpressionBuilder.NewRow(projectList));
var dbCommandTree = new DbQueryCommandTree(workspace, DataSpace.SSpace, query);
return providerServices.CreateCommandDefinition(dbCommandTree).CreateCommand().CommandText;
