我编写了一些ruby代码，从一系列插入语句中生成一个500个元素的多行插入，这比运行单个插入快得多。然后我尝试简单地将多个插入打包到一个事务中，发现我可以用更少的代码获得同样的速度。

BEGIN TRANSACTION;
INSERT INTO table VALUES (1,1,1,1);
INSERT INTO table VALUES (2,2,2,2);
...
COMMIT;

如果您使用Sqlite管理器firefox插件，它支持从INSERT SQL语句批量插入。

事实上，它不支持这一点，但Sqlite浏览器做(适用于Windows, OS X, Linux)

Sqlite3不能在SQL中直接做到这一点，除非通过一个SELECT，虽然SELECT可以返回一个“行”表达式，但我知道没有办法让它返回一个假列。

但是，CLI可以做到:

.import FILE TABLE     Import data from FILE into TABLE
.separator STRING      Change separator used by output mode and .import

$ sqlite3 /tmp/test.db
SQLite version 3.5.9
Enter ".help" for instructions
sqlite> create table abc (a);
sqlite> .import /dev/tty abc
1
2
3
99
^D
sqlite> select * from abc;
1
2
3
99
sqlite> 

如果你在INSERT中使用了一个循环，而不是使用CLI .import命令，那么一定要遵循sqlite FAQ中的建议来提高INSERT速度:

By default, each INSERT statement is its own transaction. But if you surround multiple INSERT statements with BEGIN...COMMIT then all the inserts are grouped into a single transaction. The time needed to commit the transaction is amortized over all the enclosed insert statements and so the time per insert statement is greatly reduced. Another option is to run PRAGMA synchronous=OFF. This command will cause SQLite to not wait on data to reach the disk surface, which will make write operations appear to be much faster. But if you lose power in the middle of a transaction, your database file might go corrupt.

是的，sql可以做到这一点，但是使用不同的语法。顺便说一下，sqlite文档非常好。它还会告诉您插入几行的唯一方法是使用select语句作为要插入的数据的源。

我能够使查询动态。这是我的桌子:

创造可写的“tblPlanner”文本。

我得到所有的数据通过一个JSON，所以在得到一个NSArray内的所有东西后，我遵循这个:

    NSMutableString *query = [[NSMutableString alloc]init];
    for (int i = 0; i < arr.count; i++)
    {
        NSString *sqlQuery = nil;
        sqlQuery = [NSString stringWithFormat:@" ('%@', '%@', '%@', '%@', '%@', '%@', '%@', '%@'),",
                    [[arr objectAtIndex:i] objectForKey:@"plannerid"],
                    [[arr objectAtIndex:i] objectForKey:@"probid"],
                    [[arr objectAtIndex:i] objectForKey:@"userid"],
                    [[arr objectAtIndex:i] objectForKey:@"selectedtime"],
                    [[arr objectAtIndex:i] objectForKey:@"isLocal"],
                    [[arr objectAtIndex:i] objectForKey:@"subject"],
                    [[arr objectAtIndex:i] objectForKey:@"comment"],
                    [[NSUserDefaults standardUserDefaults] objectForKey:@"applicationid"]
                    ];
        [query appendString:sqlQuery];
    }
    // REMOVING LAST COMMA NOW
    [query deleteCharactersInRange:NSMakeRange([query length]-1, 1)];

    query = [NSString stringWithFormat:@"insert into tblPlanner (plannerid, probid, userid, selectedtime, isLocal, applicationid, subject, comment) values%@",query];

最后输出查询是这样的:

insert into tblPlanner (plannerid, probid, userid, selectedtime, isLocal, applicationid, subject, comment) values 
<append 1>
('pl1176428260', '', 'US32552', '2013-06-08 12:00:44 +0000', '0', 'subj', 'Hiss', 'ap19788'),
<append 2>
('pl2050411638', '', 'US32552', '2013-05-20 10:45:55 +0000', '0', 'TERI', 'Yahoooooooooo', 'ap19788'), 
<append 3>
('pl1828600651', '', 'US32552', '2013-05-21 11:33:33 +0000', '0', 'test', 'Yest', 'ap19788'),
<append 4>
('pl549085534', '', 'US32552', '2013-05-19 11:45:04 +0000', '0', 'subj', 'Comment', 'ap19788'), 
<append 5>
('pl665538927', '', 'US32552', '2013-05-29 11:45:41 +0000', '0', 'subj', '1234567890', 'ap19788'), 
<append 6>
('pl1969438050', '', 'US32552', '2013-06-01 12:00:18 +0000', '0', 'subj', 'Cmt', 'ap19788'),
<append 7>
('pl672204050', '', 'US55240280', '2013-05-23 12:15:58 +0000', '0', 'aassdd', 'Cmt', 'ap19788'), 
<append 8>
('pl1019026150', '', 'US32552', '2013-06-08 12:15:54 +0000', '0', 'exists', 'Cmt', 'ap19788'), 
<append 9>
('pl790670523', '', 'US55240280', '2013-05-26 12:30:21 +0000', '0', 'qwerty', 'Cmt', 'ap19788')

它在代码中也运行良好，我能够成功地在SQLite中保存所有内容。

在此之前，我使工会查询东西动态，但开始给一些语法错误。不管怎样，这对我来说很好。

从版本2012-03-20(3.7.11)开始，sqlite支持以下INSERT语法:

INSERT INTO 'tablename' ('column1', 'column2') VALUES
  ('data1', 'data2'),
  ('data3', 'data4'),
  ('data5', 'data6'),
  ('data7', 'data8');
