sqlite基本语句使用

NSString *sqlCrTable = [NSString stringWithFormat:
@"CREATE TABLE IF NOT EXISTS '%@'('%@' INTEGER PRIMARY KEY AUTOINCREMENT, '%@' TEXT,'%@' TEXT)"
, rollTableName,Id,ADPicURL,flag];

NSString *sqlAdd = [NSString stringWithFormat:
@"INSERT INTO '%@' ('%@','%@') VALUES ('%@','%@')",
rollTableName, ADPicURL,flag, imageName,(i == 2)?@"FIXED":@"SCROLL"];

NSString *sqlQuery = [NSString stringWithFormat:
@"SELECT * FROM %@ order by ID limit %d",proTableName,kOnceCount];
// 只能这样取，不能用top， 一次取出几条数据

NSString *sqlQuery = [NSString stringWithFormat:
@" SELECT * FROM %@  where ID > %d order by ID limit %d"
,proTableName,self.lastIndex,kOnceCount];
