经查实，发现不是sql语句的语法错误，。。而是我批量加载sql文件的时候，文件名出错啦，数据库找不到我这个文件名。

//1.根据路径
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
    NSString *docDir = [paths objectAtIndex:0];
    NSString *fileName = [docDir stringByAppendingString:@"/teamtalk"];
    
    
    NSLog(@"数据库的路径是：%@",fileName);
    //2.获得数据库
    FMDatabase *db = [FMDatabase databaseWithPath:fileName];
    
    if([db open])
    {
        for(int i = 0;i<9;i++)
        {
            NSString *str = [NSString stringWithFormat:@"a00%d",i+1];
            NSString *filePath = [[NSBundle mainBundle] pathForResource:str ofType:@"sql"];
            
            NSError *error1;
            NSString * sql2 = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error1];
            BOOL result2 =  [db executeUpdate:sql2];
            if (result2) {
                NSLog(@"success a00%d",i+1);
            }

        }
