jchd Posted September 4 Share Posted September 4 Only the ISO timestamp format can sort natively. mm/dd/yyyy and other variations are for human consumption only; forget it in storage! You can still display the format of your choice in the resultset of a query: use string functions for that. Also, if you want local time, don't use a literal fixed value, use the 'localtime' modifier in the date functions. That way summer/winter times are correct. I recommend storing UTC times and display local times when needed. If you store local times, you never know if that was east- or west-coast time or anything in between (if you live in the US for instance).

Andreik Posted September 4 Share Posted September 4 In this case you should save date and time in database as a single column as datetime type. If you need certain portions of this data then use SQLite Date and Time functions. When the words fail... music speaks. Link to comment Share on other sites More sharing options...
jchd Posted September 4 Share Posted September 4 Looking again at your last post, I'd urge you to normalize your database.

I also have another question If several column value in a row has been inserted, how can I insert the rest that is still null? I mean how to insert / update only description part in the picture below? Oh yes, Is there any udf or function to use mysql or another sql? Could you please tell me?

HezzelQuartz Posted September 9 Author Share Posted September 9 @Andreik@jchd How can I insert description into my table below? I can use this code below to do that: update Book set Description = 'This book has newer release' where Product = 'Book A' But, can I use another command, something like: insert Into Book (Description) Values ('This book has newer release') where Product = 'Book A'? Or another command maybe? Thank You  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------  Oh yes, Is there any udf or function to use mysql or another sql?

bogQ Posted September 9 Share Posted September 9 (edited) you can not do "insert where", "update where something=something AND somethingelse=somethingelse" will do the update, insert do not have that because your inserting and as SQLite does not guarantees order it does not matter where its inserted and, so "insert where" is impossible. + that will be illogical  But you can allwayes remove before reinserting something if that is what you wish DELETE FROM x WHERE id = 1; INSERT INTO x VALUES (1, 'something', 'something', ...); Edited September 9 by bogQ TCP server and client - Learning about TCP servers and clients connectionAu3 oIrrlicht - Irrlicht projectAu3impact - Another 3D DLL game engine for autoit.

jchd Posted September 9 Share Posted September 9 You can also use UPSERT, which means update if exists else insert. Use with caution ! All of this is common to almost every SQL engine I know of (Postgres, Mysql, sql server, oracle, ...). SQLite is by far the simplest to install and use.

HezzelQuartz Posted September 13 Author Share Posted September 13 (edited) @Andreik@bogQ@jchd I have a few more question How to delete last rowid without knowing last rowid number? I tried using this one and it worked delete from Book where rowid = (SELECT max(rowid) FROM Book) Is there easier way or another good alternatif? ---------------------------------------------------------------------------------------------------------------------------------------------------- How to use _SQLite_Display2DResult_SQLite? After doing $iRval = _SQLite_GetTable2D($hDatabase, 'SELECT * FROM Book', $aResult, $iRows, $iColumns) I can continue with this below, the table is appeared  _ArrayDisplay($aResult) But, I can't continue with this below, nothing happened, no table appeared _SQLite_Display2DResult($aResult) Thank You Edited September 13 by HezzelQuartz Link to comment Share on other sites More sharing options...
bogQ Posted September 13 Share Posted September 13 (edited) Engine not having last row identifier only thing you can do is something similar to that what you already done Additional ways: "WHERE rowid = (SELECT rowid FROM your_table ORDER BY rowid ESC LIMIT 1);" or "WHERE rowid IN (... );" But i do think your way is the fastest and most easy to read  _SQLite_Display2DResult Returns or prints to Console a formated display of a 2Dimensional array Display result to console (scite console for example) if $bReturn is properly set, so it will not popup window, if changed from default it will return data to your variable Not tested it at the moment but to manage data you probably need to do something like this $data = _SQLite_Display2DResult($aResult, 0, true)  Edited September 13 by bogQ TCP server and client - Learning about TCP servers and clients connectionAu3 oIrrlicht - Irrlicht projectAu3impact - Another 3D DLL game engine for autoit.

HezzelQuartz Posted September 14 Author Share Posted September 14 @bogQ@Andreik@jchd and everyone I have another question How to select last 5 rowid? I tried using this one and I Think it worked  SELECT * FROM ProductInformation where rowid between (SELECT max(rowid)-5 FROM ProductInformation) And (SELECT max(rowid) FROM ProductInformation) Did I do anything wrong? Is there easier way or another good alternatif so that the command can be more simple and easier to read? Thank You Link to comment Share on other sites More sharing options...
jchd Posted September 14 Share Posted September 14 Use this, provided "no" is an alias for "rowid" (that is if "no" is INTEGER PRIMARY KEY): SELECT * FROM ProductInformation order by no desc limit 5; If you insist on showing this resultset in ascending "no" order, use that: select * from (SELECT * FROM ProductInformation order by no desc limit 5) order by no; This wonderful site allows debugging and testing regular expressions (many flavors available).

HezzelQuartz Posted September 30 Author Share Posted September 30 @Andreik@jchd@bogQÂ and everyone Sorry, I want to ask again From My table below, How to count how many "Pen" Appear in Category? I tried using this command, and it worked SELECT category, count(*) FROM Book where category = 'Pen' 1. Is there easier way or another good alternatif so that the command can be more simple and easier to read? 2. Could you please explain what (*) means? 3. What function in autoit should I use to insert that sqlite command above? _SQLite_QuerySingleRow? Â Link to comment Share on other sites More sharing options...
jchd Posted September 30 Share Posted September 30 1) The SQL you use is the same number of words in your question. The SQL seems quite readable to me. 2) What if you read the SQLite documentation? https://www.sqlite.org/index.html 3) Yes. You ask for one row, so get one row.

HezzelQuartz Posted October 1 Author Share Posted October 1 (edited) @jchd@bogQ@Andreik and everyone Sorry, I want to ask again From My table below, how to get only 'product' column with 'Pen' Category into arrays? I tried using this command, and it worked  _SQLite_GetTable2D($hDatabase, "SELECT Product from Book where Category = 'Pen'", $aResult, $iRows, $iColumns) MsgBox(0, "Price of Book B", $aResult[1][0]) MsgBox(0, "Price of Book B", $aResult[2][0]) MsgBox(0, "Price of Book B", $aResult[3][0]) MsgBox(0, "Price of Book B", $aResult[4][0]) 1. Is there easier way or another good alternatif so that the command can be more simple and easier to read? 2. Actually I prefer to use any function similar to _SQLite_QuerySingleRow, Can I use another function? maybe _SQLite_Query? 3. If _SQLite_Query can be used, I am confused. How to use that function? Could you all please give any idea, clue, or else? Edited October 1 by HezzelQuartz Link to comment Share on other sites More sharing options...
jchd Posted October 1 Share Posted October 1 For resultset with only one column and more than one row, use _SQLite_GetTable() For resultset with more columns and more than one row, use _SQLite_GetTable2D() Forget _SQLite_Query and friends.
