前幾天做項(xiàng)目倔毙，需要獲取數(shù)據(jù)庫中本地收藏文章的數(shù)量，然后百度到方法，記錄一下映凳。
<pre>
+(NSInteger)getLocalCasesCountByTable{
if ([[LPDataBase sharedDatabase].database open]) {
LPUser * user =[KBCoordinatingContext sharedInstance].userInfo;
NSString *selectSQL = [NSString stringWithFormat:@"SELECT Count(*) FROM %@ where UserID = '%@' and Draft = '1'",KTopicList,user.UserID];
return [[LPDataBase sharedDatabase].database intForQuery:selectSQL];
}
return 0;
}
</pre>
[NSString stringWithFormat:@"SELECT Count(*) FROM %@ where UserID = '%@' and Draft = '1'",KTopicList,user.UserID]
KTopicList 表名
user.UserID 參數(shù)
