示例1: UpsertByKeyFields
internal static object UpsertByKeyFields(string tableName, DataStrategy dataStrategy, object entity, IEnumerable<string> keyFieldNames, bool isResultRequired, ErrorCallback errorCallback)
{
var record = UpdateCommand.ObjectToDictionary(entity);
var list = record as IList<IDictionary<string, object>>;
if (list != null) return dataStrategy.UpsertMany(tableName, list, keyFieldNames, isResultRequired, errorCallback);
var dict = record as IDictionary<string, object>;
var criteria = GetCriteria(keyFieldNames, dict);
var criteriaExpression = ExpressionHelper.CriteriaDictionaryToExpression(tableName, criteria);
return dataStrategy.Upsert(tableName, dict, criteriaExpression, isResultRequired);
}示例2: UpsertUsingKeys
private static object UpsertUsingKeys(DataStrategy dataStrategy, DynamicTable table, object[] args, bool isResultRequired)
{
var record = ObjectToDictionary(args[0]);
var list = record as IList<IDictionary<string, object>>;
if (list != null)
{
ErrorCallback errorCallback = (args.Length == 2 ? args[1] as ErrorCallback : null) ??
((item, exception) => false);
return dataStrategy.UpsertMany(table.GetQualifiedName(), list, isResultRequired, errorCallback);
}
var dict = record as IDictionary<string, object>;
if (dict == null) throw new InvalidOperationException("Could not resolve data from passed object.");
var key = dataStrategy.GetAdapter().GetKey(table.GetQualifiedName(), dict);
var criteria = ExpressionHelper.CriteriaDictionaryToExpression(table.GetQualifiedName(), key);
return dataStrategy.Upsert(table.GetQualifiedName(), dict, criteria, isResultRequired);
}示例3: Execute
public object Execute(DataStrategy dataStrategy, DynamicTable table, InvokeMemberBinder binder, object[] args)
{
object result;
if (binder.HasSingleUnnamedArgument() || args.Length == 2 && args[1] is ErrorCallback)
{
result = UpsertByKeyFields(table.GetQualifiedName(), dataStrategy, args[0],

!binder.IsResultDiscarded(),
args.Length == 2 ? (ErrorCallback)args[1] : ((item, exception) => false));
}
else
{

var criteriaExpression = ExpressionHelper.CriteriaDictionaryToExpression(table.GetQualifiedName(),
criteria);
var data = binder.NamedArgumentsToDictionary(args);
result = dataStrategy.Upsert(table.GetQualifiedName(), data, criteriaExpression, !binder.IsResultDiscarded());
}
return ResultHelper.TypeResult(result, table, dataStrategy);
