使用＆＃34;从DB导出SQLite3表：错误：没有这样的归类序列：IUNICODE＆＃34;

Question

使用DB Browser for SQLite，您现在可以从databases with IUNICODE collation sequence errors成功导出表格，但这是使用数据库浏览器GUI的手动过程。我使用了数据库浏览器，因为如果你尝试使用bash或sqlite控制台中的sqlite3导出表，你会得到：

Error: no such collation sequence: IUNICODE

由于DB Browser似乎没有命令行选项（这是正确的吗？），我正在寻找另一种方法，所以我可以自动导出表格，最好使用bash脚本。

根据CL在下面的回复......做了以下事情：

sqlite3 /home/lpc123/data/MM.DB "SELECT sql FROM sqlite_master WHERE type='table' AND name='Songs';" 

...生成了一长串表定义：

CREATE TABLE Songs (ID INTEGER PRIMARY KEY AUTOINCREMENT,Artist TEXT COLLATE IUNICODE,IDAlbum INTEGER,Album TEXT COLLATE IUNICODE,AlbumArtist TEXT COLLATE IUNICODE,DiscNumber TEXT COLLATE IUNICODE,TrackNumber TEXT COLLATE IUNICODE,SongTitle TEXT COLLATE IUNICODE,SongPath TEXT COLLATE IUNICODE,Extension TEXT(5),Year INTEGER,Genre TEXT COLLATE IUNICODE,FileLength INTEGER,SongLength INTEGER,IDMedia INTEGER,CacheStatus INTEGER,CacheName TEXT COLLATE IUNICODE,Rating INTEGER,Bitrate INTEGER,Seekable INTEGER,Broadcast INTEGER,PreviewState INTEGER,PreviewName TEXT COLLATE IUNICODE,PreviewStartTime INTEGER,PreviewLength INTEGER,Author TEXT COLLATE IUNICODE,SamplingFrequency INTEGER,Stereo INTEGER,VBR INTEGER,BPM INTEGER,SignType INTEGER,SignPart1 INTEGER,SignPart2 INTEGER,SignPart3 INTEGER,SignPart4 INTEGER,PlayCounter INTEGER,LastTimePlayed REAL,AudioCDTrack INTEGER,FileModified REAL,TrackModified REAL,MaxSample REAL,NormalizeTrack REAL,NormalizeAlbum REAL,Custom1 TEXT COLLATE IUNICODE,Custom2 TEXT COLLATE IUNICODE,Custom3 TEXT COLLATE IUNICODE,Custom4 TEXT COLLATE IUNICODE,Custom5 TEXT COLLATE IUNICODE,DateAdded REAL,OrigFileLength INTEGER,PreGap INTEGER,PostGap INTEGER,TotalSamples INTEGER,PlaybackPos INTEGER,GaplessBytes INTEGER,IDFolder INTEGER,IDEpisode INTEGER,TrackType INTEGER,Copyright TEXT COLLATE IUNICODE,Publisher TEXT COLLATE IUNICODE,Encoder TEXT COLLATE IUNICODE,Lyricist TEXT COLLATE IUNICODE,Conductor TEXT COLLATE IUNICODE,Remixer TEXT COLLATE IUNICODE,InvolvedPeople TEXT COLLATE IUNICODE,OrigTitle TEXT COLLATE IUNICODE,OrigArtist TEXT COLLATE IUNICODE,OrigLyricist TEXT COLLATE IUNICODE,GroupDesc TEXT COLLATE IUNICODE,SubTitle TEXT COLLATE IUNICODE,ISRC TEXT COLLATE IUNICODE,InitialKey TEXT COLLATE IUNICODE,Language TEXT COLLATE IUNICODE,WebCommercial TEXT COLLATE IUNICODE,WebCopyright TEXT COLLATE IUNICODE,WebFilepage TEXT COLLATE IUNICODE,WebArtist TEXT COLLATE IUNICODE,WebSource TEXT COLLATE IUNICODE,WebRadio TEXT COLLATE IUNICODE,WebPayment TEXT COLLATE IUNICODE,WebPublisher TEXT COLLATE IUNICODE,WebUser TEXT COLLATE IUNICODE,OrigYear INTEGER,Tempo TEXT COLLATE IUNICODE,Mood TEXT COLLATE IUNICODE,Occasion TEXT COLLATE IUNICODE,Quality TEXT COLLATE IUNICODE,Lyrics TEXT COLLATE IUNICODE,Comment TEXT COLLATE IUNICODE, StartTime INTEGER, StopTime INTEGER, SkipCount INTEGER, VideoWidth INTEGER, VideoHeight INTEGER, FrameRate INTEGER, ContainerType INTEGER, StreamCount INTEGER, StreamInfo TEXT, EpisodeNumber TEXT COLLATE IUNICODE, SeasonNumber TEXT COLLATE IUNICODE, Actors TEXT COLLATE IUNICODE, Producer TEXT COLLATE IUNICODE, ParentalRating TEXT COLLATE IUNICODE, ArtworkModified REAL)

删除了＆＃34; COLLATE IUNICODE＆＃34;的所有实例从那个字符串：

CREATE TABLE Songs (ID INTEGER PRIMARY KEY AUTOINCREMENT,Artist TEXT ,IDAlbum INTEGER,Album TEXT ,AlbumArtist TEXT ,DiscNumber TEXT ,TrackNumber TEXT ,SongTitle TEXT ,SongPath TEXT ,Extension TEXT(5),Year INTEGER,Genre TEXT ,FileLength INTEGER,SongLength INTEGER,IDMedia INTEGER,CacheStatus INTEGER,CacheName TEXT ,Rating INTEGER,Bitrate INTEGER,Seekable INTEGER,Broadcast INTEGER,PreviewState INTEGER,PreviewName TEXT ,PreviewStartTime INTEGER,PreviewLength INTEGER,Author TEXT ,SamplingFrequency INTEGER,Stereo INTEGER,VBR INTEGER,BPM INTEGER,SignType INTEGER,SignPart1 INTEGER,SignPart2 INTEGER,SignPart3 INTEGER,SignPart4 INTEGER,PlayCounter INTEGER,LastTimePlayed REAL,AudioCDTrack INTEGER,FileModified REAL,TrackModified REAL,MaxSample REAL,NormalizeTrack REAL,NormalizeAlbum REAL,Custom1 TEXT ,Custom2 TEXT ,Custom3 TEXT ,Custom4 TEXT ,Custom5 TEXT ,DateAdded REAL,OrigFileLength INTEGER,PreGap INTEGER,PostGap INTEGER,TotalSamples INTEGER,PlaybackPos INTEGER,GaplessBytes INTEGER,IDFolder INTEGER,IDEpisode INTEGER,TrackType INTEGER,Copyright TEXT ,Publisher TEXT ,Encoder TEXT ,Lyricist TEXT ,Conductor TEXT ,Remixer TEXT ,InvolvedPeople TEXT ,OrigTitle TEXT ,OrigArtist TEXT ,OrigLyricist TEXT ,GroupDesc TEXT ,SubTitle TEXT ,ISRC TEXT ,InitialKey TEXT ,Language TEXT ,WebCommercial TEXT ,WebCopyright TEXT ,WebFilepage TEXT ,WebArtist TEXT ,WebSource TEXT ,WebRadio TEXT ,WebPayment TEXT ,WebPublisher TEXT ,WebUser TEXT ,OrigYear INTEGER,Tempo TEXT ,Mood TEXT ,Occasion TEXT ,Quality TEXT ,Lyrics TEXT ,Comment TEXT , StartTime INTEGER, StopTime INTEGER, SkipCount INTEGER, VideoWidth INTEGER, VideoHeight INTEGER, FrameRate INTEGER, ContainerType INTEGER, StreamCount INTEGER, StreamInfo TEXT, EpisodeNumber TEXT , SeasonNumber TEXT , Actors TEXT , Producer TEXT , ParentalRating TEXT , ArtworkModified REAL)

使用PRAGMA writable_schema = 1启用对sqlite_master的写访问权：

sqlite3 /home/lpc123/data/MM.DB "PRAGMA writable_schema=1;"

这是事情发生故障或先前命令未采取的地方：

将新表定义写入其中

UPDATE sqlite_master SET sql =＆＃39; ...＆＃39; WHERE type =＆＃39; table＆＃39; AND name =＆＃39; MonkeyTable＆＃39 ;; 我认为这意味着：

sqlite3 /home/lpc123/data/MM.DB "UPDATE sqlite_master SET sql='CREATE TABLE Songs (ID INTEGER PRIMARY KEY AUTOINCREMENT,Artist TEXT ,IDAlbum INTEGER,Album TEXT ,AlbumArtist TEXT ,DiscNumber TEXT ,TrackNumber TEXT ,SongTitle TEXT ,SongPath TEXT ,Extension TEXT(5),Year INTEGER,Genre TEXT ,FileLength INTEGER,SongLength INTEGER,IDMedia INTEGER,CacheStatus INTEGER,CacheName TEXT ,Rating INTEGER,Bitrate INTEGER,Seekable INTEGER,Broadcast INTEGER,PreviewState INTEGER,PreviewName TEXT ,PreviewStartTime INTEGER,PreviewLength INTEGER,Author TEXT ,SamplingFrequency INTEGER,Stereo INTEGER,VBR INTEGER,BPM INTEGER,SignType INTEGER,SignPart1 INTEGER,SignPart2 INTEGER,SignPart3 INTEGER,SignPart4 INTEGER,PlayCounter INTEGER,LastTimePlayed REAL,AudioCDTrack INTEGER,FileModified REAL,TrackModified REAL,MaxSample REAL,NormalizeTrack REAL,NormalizeAlbum REAL,Custom1 TEXT ,Custom2 TEXT ,Custom3 TEXT ,Custom4 TEXT ,Custom5 TEXT ,DateAdded REAL,OrigFileLength INTEGER,PreGap INTEGER,PostGap INTEGER,TotalSamples INTEGER,PlaybackPos INTEGER,GaplessBytes INTEGER,IDFolder INTEGER,IDEpisode INTEGER,TrackType INTEGER,Copyright TEXT ,Publisher TEXT ,Encoder TEXT ,Lyricist TEXT ,Conductor TEXT ,Remixer TEXT ,InvolvedPeople TEXT ,OrigTitle TEXT ,OrigArtist TEXT ,OrigLyricist TEXT ,GroupDesc TEXT ,SubTitle TEXT ,ISRC TEXT ,InitialKey TEXT ,Language TEXT ,WebCommercial TEXT ,WebCopyright TEXT ,WebFilepage TEXT ,WebArtist TEXT ,WebSource TEXT ,WebRadio TEXT ,WebPayment TEXT ,WebPublisher TEXT ,WebUser TEXT ,OrigYear INTEGER,Tempo TEXT ,Mood TEXT ,Occasion TEXT ,Quality TEXT ,Lyrics TEXT ,Comment TEXT , StartTime INTEGER, StopTime INTEGER, SkipCount INTEGER, VideoWidth INTEGER, VideoHeight INTEGER, FrameRate INTEGER, ContainerType INTEGER, StreamCount INTEGER, StreamInfo TEXT, EpisodeNumber TEXT , SeasonNumber TEXT , Actors TEXT , Producer TEXT , ParentalRating TEXT , ArtworkModified REAL)' WHERE type='table' AND name='Songs';"

导致此错误：

Error: table sqlite_master may not be modified

我想也许关于创建表的部分不属于，所以这次没有CREATE TABLE部分再试一次：

sqlite3 /home/lpc123/data/MM.DB "UPDATE sqlite_master SET sql='TABLE Songs (ID INTEGER PRIMARY KEY AUTOINCREMENT,Artist TEXT ,IDAlbum INTEGER,Album TEXT ,AlbumArtist TEXT ,DiscNumber TEXT ,TrackNumber TEXT ,SongTitle TEXT ,SongPath TEXT ,Extension TEXT(5),Year INTEGER,Genre TEXT ,FileLength INTEGER,SongLength INTEGER,IDMedia INTEGER,CacheStatus INTEGER,CacheName TEXT ,Rating INTEGER,Bitrate INTEGER,Seekable INTEGER,Broadcast INTEGER,PreviewState INTEGER,PreviewName TEXT ,PreviewStartTime INTEGER,PreviewLength INTEGER,Author TEXT ,SamplingFrequency INTEGER,Stereo INTEGER,VBR INTEGER,BPM INTEGER,SignType INTEGER,SignPart1 INTEGER,SignPart2 INTEGER,SignPart3 INTEGER,SignPart4 INTEGER,PlayCounter INTEGER,LastTimePlayed REAL,AudioCDTrack INTEGER,FileModified REAL,TrackModified REAL,MaxSample REAL,NormalizeTrack REAL,NormalizeAlbum REAL,Custom1 TEXT ,Custom2 TEXT ,Custom3 TEXT ,Custom4 TEXT ,Custom5 TEXT ,DateAdded REAL,OrigFileLength INTEGER,PreGap INTEGER,PostGap INTEGER,TotalSamples INTEGER,PlaybackPos INTEGER,GaplessBytes INTEGER,IDFolder INTEGER,IDEpisode INTEGER,TrackType INTEGER,Copyright TEXT ,Publisher TEXT ,Encoder TEXT ,Lyricist TEXT ,Conductor TEXT ,Remixer TEXT ,InvolvedPeople TEXT ,OrigTitle TEXT ,OrigArtist TEXT ,OrigLyricist TEXT ,GroupDesc TEXT ,SubTitle TEXT ,ISRC TEXT ,InitialKey TEXT ,Language TEXT ,WebCommercial TEXT ,WebCopyright TEXT ,WebFilepage TEXT ,WebArtist TEXT ,WebSource TEXT ,WebRadio TEXT ,WebPayment TEXT ,WebPublisher TEXT ,WebUser TEXT ,OrigYear INTEGER,Tempo TEXT ,Mood TEXT ,Occasion TEXT ,Quality TEXT ,Lyrics TEXT ,Comment TEXT , StartTime INTEGER, StopTime INTEGER, SkipCount INTEGER, VideoWidth INTEGER, VideoHeight INTEGER, FrameRate INTEGER, ContainerType INTEGER, StreamCount INTEGER, StreamInfo TEXT, EpisodeNumber TEXT , SeasonNumber TEXT , Actors TEXT , Producer TEXT , ParentalRating TEXT , ArtworkModified REAL)' WHERE type='table' AND name='Songs';"

这也不起作用。

Answer 1

您可以修改数据库以删除对该排序规则的所有引用。

阅读表格定义：

SELECT sql FROM sqlite_master WHERE type='table' AND name='MonkeyTable';

从字符串中删除COLLATE IUNICODE，然后使用PRAGMA writable_schema=1;启用对sqlite_master的写访问权限，并将新表定义写入其中：

UPDATE sqlite_master SET sql='...' WHERE type='table' AND name='MonkeyTable';

如果您确实希望以交互方式执行此操作，则必须在同一会话中执行这两个语句：

sqlite3 mm.db "PRAGMA writable_schema=1; UPDATE sqlite_master ..."

之后，重新打开数据库，然后运行REINDEX（因为更改排序规则会使所有索引内容无效）。

Answer 2

答案是script posted here，它将数据库中包含的所有表格提取到单个CSV文件中，并且可以在bash中运行。在这种情况下，所需的输出是一个表，并命名为songs.csv。

然后，您可以创建一个SQL文件：import.sql，您必须定制该文件以包含提取的表中显示的所有列（此示例显示四列）：

CREATE TABLE Songs (ID varchar(255) not null, Artist varchar(255) not null, IDAlbum varchar(255) not null, Album varchar(255) not null);
.separator ,
.import songs.csv Songs

现在您可以在bash中运行以下命令：

sqlite3 currdb.sqlite < import.sql

...创建一个包含导入表的可访问数据库。

Answer 3

适用于MediaMonkey用户的解决方案：

1。）从此处下载适用于Windows的“命令行SQLite工具包”：https://sqlite.org/download.html（档案实际上称为sqlite-tools-win32-x86-3330000.zip，但对于64位不存在，32位可以正常工作）

2。）解压缩ZIP文件，您至少需要文件sqlite3.exe

3。）始终创建MM.DB的副本，请勿将原始副本用于以下步骤！

4。）使用CopyOfMM.DB在CMD窗口中打开sqlite3.exe CopyOfMM.DB

5。）在sqlite提示符上，执行以下命令：

SELECT sql FROM sqlite_master WHERE type='table' AND name='Songs';

6。）将完整的CREATE TABLE输出文本复制到诸如Notepad ++之类的编辑器中

7。）将所有COLLATE IUNICODE个文本出现替换为空白（将其删除）

8。）使用.quit退出sqlite提示

9。）在CMD窗口中单行执行以下命令（将CREATE TABLE Songs部分完全替换为您在步骤＃7中修改的文本。此文本在MediaMonkey-Versions之间有所不同！添加后缀{{ 1}}）

' WHERE type='table' AND name='Songs';"

这只需要一秒钟。

9a）如果要确定此命令是否更改了表定义，请重复步骤＃4和＃5，并再次检查是否不再有IUNICODE COLLATION。退出sqlite3.exe提示符。

10。）使用以下命令为表Songs重新索引：

sqlite3.exe CopyOfMM.DB "PRAGMA writable_schema=1; UPDATE sqlite_master SET sql='CREATE TABLE Songs (......)' WHERE type='table' AND name='Songs';"

这需要一分钟左右的时间，具体取决于该表中条目的数量。

现在，您终于可以为Songs表执行任何sqlite命令了，而不会出现“错误：没有这样的排序顺序：IUNICODE”

要重复此操作：请勿使用原始的MediaMonkey数据库执行此操作！
