Exporting a SQLite3 Table from a DB with "Error: no such collation sequence: IUNICODE"

Question

使用DB Browser for SQLite, you can now successfully export a table from databases with IUNICODE collation sequence errors，但它是使用 DB Browser 的 GUI 的手动过程。我使用 DB 浏览器是因为如果您尝试使用 sqlite3 从 bash 或从 sqlite 控制台导出 table，您会得到：

Error: no such collation sequence: IUNICODE

由于 DB 浏览器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以便我可以自动导出 table，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 table 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)

从该字符串中删除了 "COLLATE IUNICODE" 的所有实例：

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 的写入访问

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

这里出现故障或之前的命令没有执行）：

将您的新 table 定义写入其中

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

导致此错误的原因：

Error: table sqlite_master may not be modified

我想也许关于创建 table 的部分不属于，所以这次我在没有创建 TABLE 部分的情况下再次尝试：

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';"

那也没用。

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 table 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，并将新的 table 定义写入其中:

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

如果您确实想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，运行 REINDEX（因为更改排序规则导致所有索引内容无效）。

Answer 2

答案是，它将数据库中包含的所有 table 提取到单独的 CSV 文件中，并且可以是 bash 中的运行。在这种情况下，需要的输出是一个 table，并被命名为 songs.csv.

然后您可以创建一个 SQL 文件：import.sql 您必须对其进行定制以包含提取的 table 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

现在您可以运行 bash 中的以下内容：

sqlite3 currdb.sqlite < import.sql

...创建一个可访问的数据库，其中包含您导入的 table.

Answer 3

适用于 MediaMonkey 用户的有效解决方案：

1.) 从此处下载 windows 的 'a bundle of command-line SQLite tools'：https://sqlite.org/download.html（存档实际上称为 sqlite-tools-win32-x86-3330000.zip，64 位不存在，32 位有效很好。）

2.) 解压ZIP文件，你至少需要文件sqlite3.exe

3.) 始终创建您的 MM.DB 的副本，切勿在以下步骤中使用原始副本！

4.) 使用 sqlite3.exe CopyOfMM.DB

在 CMD window 中打开你的 CopyOfMM.DB

5.) 在 sqlite-prompt 上执行此命令：

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

6.) 将完整的 CREATE TABLE 输出文本复制到像 Notepad++ 这样的编辑器中

7.) 将所有出现的 COLLATE IUNICODE 文本替换为空（删除）

8.) 使用 .quit

退出 sqlite-prompt

9.) 在 CMD window 中以 one-liner 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!添加后缀' WHERE type='table' AND name='Songs';")

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

这只需要一秒钟。

9a) 如果您想确定此命令是否更改了您的 table 定义，请重复步骤 #4 和 #5 并仔细检查是否不再有 IUNICODE COLLATION。退出 sqlite3.exe 提示。

10.) 使用以下命令重新索引您的 table 歌曲：

sqlite3.exe CopyOfMM.DB "REINDEX Songs;"

这需要一分钟左右的时间，具体取决于此 table 中的条目数量。

现在您终于可以为您的歌曲执行任何 sqlite 命令 table 而不会出现“错误：没有这样的整理顺序：IUNICODE”

重复一遍：不要用你原来的 MediaMonkey 数据库做这个！
