jchd Posted July 17, 2014 Share Posted July 17, 2014 (edited) Ticket #2778 is asking for an implementation. I don't believe there is a common need for inclusion of such feature in the standard delivery. I compiled the regex.c source from the official SQLite 3.8.5 distribution and tested it. It works decently well but don't expect it to be fast compared to built-in possibilities. Please refer to the official source where you'll find details about supported pattern elements. For those who want to try it, you can download a 32-bit extension DLL. It has been compiled with x86 tcc so it's not highly optimized (which doesn't matter much in this case). You'll find >in this post support to manage SQLite extensions. EDIT: Dropbox once again decided to kill old links.

Andreik Posted July 27, 2014 Share Posted July 27, 2014 Thanks for sharing. I made an example script: #include <SQLite.au3> #include <SQLite.dll.au3> #include <SQLiteExtLoad.au3> Local $aResult, $iRows, $iColumns _SQLite_Startup() $hDB = _SQLite_Open() _SQLite_EnableExtensions($hDB,1) _SQLite_LoadExtension($hDB,@ScriptDir & '\regexp.dll','sqlite3_regexp_init') _SQLite_Exec($hDB,"CREATE TABLE Example(ID int,Data varchar(50))") For $Index = 1 To 2000 _SQLite_Exec($hDB,"INSERT INTO Example(ID,Data) VALUES(" & $Index & "," & _SQLite_FastEscape(RandomChars()) & ")") Next _SQLite_GetTable2d($hDB,"SELECT ID,Data FROM Example WHERE Data REGEXP '^\d{3}'",$aResult,$iRows,$iColumns) _SQLite_Display2DResult($aResult) _SQLite_Close($hDB) Func RandomChars() Local $sChars Local $aCharset = StringSplit('abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789','') For $Index = 1 To 50 $sChars &= $aCharset[Random(1,$aCharset[0],1)] Next Return $sChars EndFunc When the words fail... music speaks.

Here's the X86 .dll and the source file: sqlite3-pcre.zip 81.17 kB · 18 downloads sqlite3-pcre-src.zip 329.38 kB · 18 downloads The regex engine used is PCRE v1, the same as AutoIt currently uses. Yes , I had downloaded it previously. but it threw an error when I run Andreik's scirpt such as below: ! SQLite.au3 Error --> Function: _SQLite_Query --> Query: SELECT ID,Data FROM Example WHERE Data REGEXP '^\d{3}' --> Error: no such function: REGEXP And of course , Error still occurs when I re-download these files you offer and rename the file to regexp.dll within sqlite3-pcre.zip Would you please tell me what's wrong with it ?

jchd Posted January 7, 2023 Author Share Posted January 7, 2023 Sorry, I didn't look at the example code dated 2014! This code was for the first version of the DLL, which used the minimal regex engine available in the SQLite source tree. My version uses a differently named init function. So change the code to: _SQLite_LoadExtension($hDB,@ScriptDir & '\sqlite3-pcre.dll','sqlite3_extension_init') Of course, adapt DLL name and location.
