IOS 无法为查询编译语句

Question

我编写了一个应用程序，将联系人从服务器同步到客户端。但我有一个问题，我从服务器到客户端获取所有联系人，当我保存一些联系人时，应用程序错误。

AB: Could not compile statement for query (ABCCopyArrayOfAllInstancesOfClassInSourceMatchingProperties):
SELECT ROWID, Name, ExternalIdentifier, Type, ConstraintsPath, ExternalModificationTag, ExternalSyncTag, AccountID, Enabled, SyncData, MeIdentifier, Capabilities FROM ABStore WHERE Enabled = ?;
