Quotes in query SQLite...

Recommended Posts

Hi guys! How are you? Hope you're fine :)
I'm trying to insert a text that contains quotes in a SQLite database, and I don't know how to do.
I tried with:

Local $sString = "1P6AV2104'0HA04'0AA0"
StringReplace($sString, "'", "''")

but I didn't managed to, obtaining this error:

--> Error:    unrecognized token: "0HA04"

How can I manage to solve this problem? Thanks :)

You really should specify datatypes in the create table statement, else you may have issues.

The function _SQLite_FastEscape() deals with single quote(s) in text fields.

Don't wrap numeric fields inside single quotes.

Use a transaction to group your inserts.

@jchd

Could you please post an example of what you said? Thanks and have a good day :)

EDIT:

I would like to understand your phrase too:

"Use a transaction to group your inserts."

I am writing from my smartphone, so, sorry If I didn't quote you in right way :) Thanks :)

@jchd
Hey! It works :) Thanks :)

ID it's not numeric, so I processed it as text...
COSTO would be real, but when I do the "INSERT", an error appears in corrispondence of the field "COSTO"... So I am trrating it as text...
Just to know... Even when I do some UPDATE I have to do proceed with "_SQLite_FastEscape()" function? A big thank you :D

EDIT:

Costo is effectively REAL, because it's like € xx,xx...
So, I would declare it as REAL and don't do pass it to the _SQLite_FastEscape() function, am I right?
If you could me explain these things, I'd be very happy and, if you need some example of what I'm meaning, just ask :)

Again thanks :D

A real for a computer is of the form 9999.9999 with no € sign and a dot as decimal point, not a comma. You can reformat the cost value so that is fits what is expected for a real. Integers and reals don't need escaping, clrealy, since they can't contain single quotes.

Update needs escaping text like insert and for the very same reason.

Anyway you may still want to reconsider your table design to avoid maintaining separate tables for different manufacturers/suppliers (if those tables have the same fields). IIRC you mentionned Siemens and Rockwell or something. Do those tables have the same structure?

Good morning @jchd:)
For the first question, I should replace the € with "", and, " , " with "."... Then, I could proceed with the "REAL" format for the field COSTO.
Fot the second question, I answer "Yes, all 4 tables ( are 4, not 2 as I, maybe, didn't explain in the right way ), have the same format... But, I preferred to keep them separate because, If I have to make a query, the SQLite has not to query a big table, but just the needed one. If I'm making some mistakes ( as I did, because I studied SQL few years ago ), please tell me :)
Now I'm making changes about the INSERT and the UPDATE. Only these 2 "operations" would have the _SQLite_FastEscape() function, am I right?
Thanks for your time :) I rellay appreciate it :)
Have a wonderful day!
Francesco :D

For the costo field: also remove whitespaces.

Querying one "big" table is almost always preferable to have several identical tables. There are some reasons for that:

  • First, SQLite (and RDBMS in general) are very efficient at manipulating huge amounts of data. SQLite routinely manages multi-terabytes tables with billions rows, provided correct design of the schema.
  • Second, you don't have to write and manage separate code to access TableA, TableB, TableC, ... Add a discriminating column (e.g. "Brand") where you put 'Siemens', 'Rockwell', ...(*) and use a WHERE clause to specify which brand you're interessed in.
  • Third, it's better for efficiency of the caches.

(*) Better yet: set the column "Brand" to refer to a Brands table, using a foreign key.

You need to escape any text literal which may contain one or more single quote. This includes statements like:

select colA, colB, colC from mytable where colA like _SQLiteFastEscape($sometext) ...

Hey @jchd!
You are a very nice person :)
No one here helped me so much, and, since you starded doing that, I'm learning a lot of things...
Now, I should change my code ( 1783 rows :frantics: ) about what you were saying...
I know I can do it :D
Quick question... I don't remember how FK works...
Could you explain me something about it or give to me ( I am not lazy looking for foreign key on Google, but maybe you have a more direct explanation that I could understand better than something on Google :) ) a reference :)
Thanks :D 

EDIT:

By the way, I don't know if I'll do this new table, because I can't manage one brand with barcodes...
If I add a new product, I do it by barcode... So, If the last brand has not a barcode, and atm, I can't generate it, I can't do what you suggested ( would be AMAZING! )... Do you have any idea? Or, for now, I could manage the db as I am doing, without creating a new table with all brands? Thanks :D

A foreign key in SQL is a reference (via a unique identifier, often an integer) from a child table to a parent table. Foreign keys are widely used to avoid duplication of data (like in your case, to avoid repeating for every Siemens item that its brand is 'Siemens') and also to link together entities in different semantic spaces.

Duplicating data is problematic: not only that eats up storage and cache space pointlessly but also because it's a window wide open to DB inconsistancies. For instance, it too easy to misspell/mistype 'Siemens' as 'Seimens'.

Now imagine you have a stock of items (you seem to have that) which you sell. Let's skip a number of details. At some point you're going to have to process orders and produce detailled invoices. At this point, what do you think is more robust, more efficient and more compact?

Create invoices containing the full data of the client, the delivery point and all the items sold stated in full,
OR
Create invoices containing references to the client, the delivery point and sold items.

Obviously, the second paradigm is better. You achieve that by using, in the invoices table, foreign keys (= FK = reference) to the client entry in the client table, also FK to the delivery point in the corresponding table and also FK to item in the stock table for each sold item in the invoice.

For a complete documentation about FK under SQLite, turn to https://www.sqlite.org/foreignkeys.html

Thanks for your explanation, @jchd.
But, how would I apply your example to my script? Should I create a table "Brand", and then?

Most probably yes. DB design obeys both rules ("normalizations", to apply reasonnably) and some white magic. Context & requirements & experience & common sense are the guides.

      So I am trying to implement an archive system of sorts for my (SQLite) DB app. I wrote a function to attach a separate (archive) DB and
      sync the columns with main DB. If archive DB file does not exist, create file with _SQLiteOpen then close the file (and thus connection) with SQLite_Close.
      This works as intended, however, after the create operation, all subsequent _SQLite_* functions returned a "Library misuse error".
      After a little digging I found the problem in the _SQLite_Close function: it clears the "last opened database" handle even when there still is a live
      DB connection open. All other functions then "think" there is no DB connection active. I hacked two functions in the UDF for a quick fix:

      In _SQLite_Close: Change
      ... $__g_hDB_SQLite = 0 __SQLite_hDel($__g_ahDBs_SQLite, $hDB) Return $iRval[0] to:
      $__g_hDB_SQLite = __SQLite_hDel($__g_ahDBs_SQLite, $hDB) Return $iRval[0] and in Func __SQLite_hDel changed
      Func __SQLite_hDel(ByRef $ahLists, $hGeneric) Local $iElement = _ArraySearch($ahLists, $hGeneric) If $iElement > 0 Then _ArrayDelete($ahLists, $iElement) EndFunc ;==>__SQLite_hDel to:
      Func __SQLite_hDel(ByRef $ahLists, $hGeneric) Local $iElement = _ArraySearch($ahLists, $hGeneric) If $iElement > 0 Then _ArrayDelete($ahLists, $iElement) Return $ahLists[UBound($ahLists)-1] ; Return last opened db EndIf Return 0 EndFunc ;==>__SQLite_hDel so it preserves last opened DB again.
       
      My archive function now works great
      I'm not sure if this should be classified as a bug, but I believe so...
      Hope this helps someone before

      and for that, this can help, obviously only when declared in the SQLite table.

      I was thinking but I don't have the experience, so you may have the experience.
      I was thinking to chop a DB with 100.000 ( 20 columns ) in 10.000 DB chunks ( 10 DBs ) and query concurrently all of them to speed up a search, then add the results. Is that a sound idea ? Or will I run in trouble down the road. Should a DB better be keep in one piece ?
      The DB is now in MySQL. I wanna do all this chopping and use SQLite. 
      Thanks

      Hi
      I am trying to set Accelerator keys from an array.
      I select the KEY and CONTROL from a SQLite table, the Array looks like that generated for the Helpfile, but I can't get the CONTROLS to resolve...
      I though about Assign & Eval, but not sure if that's a step in the right direction. IsDeclared shows that the $var exists in Local Scope -1.  
       
      Local $Main = GUICreate("Custom MsgBox", 225, 80) GUICtrlCreateLabel("Please select a button.", 10, 10) Local $idButton_Yes = GUICtrlCreateButton("Yes", 10, 50, 65, 25) Local $idButton_No = GUICtrlCreateButton("No", 80, 50, 65, 25) Local $idButton_Exit = GUICtrlCreateButton("Exit", 150, 50, 65, 25) Local $query, $aResult, $iRows, $iColumns $query = "" ;reset $query = "Select hotkey_key, hotkey_ctrl from mytable where mykeys = 'hotkey' ; " ; ; Query $iRval = _SQLite_GetTable2d($sqliteDb, $query, $aResult, $iRows, $iColumns) If $iRval = $SQLITE_OK Then Local $sizeofHotkeys = UBound($aResult) - 1 ConsoleWrite("$sizeofHotkeys " & $sizeofHotkeys & @CRLF) If $sizeofHotkeys > 0 Then Local $main__aAccelKeys[$sizeofHotkeys][2] For $i = 0 To $sizeofHotkeys - 1 $j = $i + 1 ; replace friendly text with code -- ! alt + Shift ^ Ctrl # Windows $aResult[$j][0] = StringReplace($aResult[$j][0], "Alt", "!") $aResult[$j][0] = StringReplace($aResult[$j][0], "Shift", "+") $aResult[$j][0] = StringReplace($aResult[$j][0], "Ctrl", "^") $main__aAccelKeys[$i][0] = $aResult[$j][0] ;--- $main__aAccelKeys[$i][1] = $aResult[$j][1] ;--- Next ;~ Row|Col 0|Col 1 ;~ Row 0|F2|$idButton_Yes ;~ Row 1|F3|$idButton_No _DebugArrayDisplay($main__aAccelKeys) Local $rv = GUISetAccelerators($main__aAccelKeys, $Main) GUISetState(@SW_SHOW) ; Display the GUI.  
      Please note that this is a modified Helpfile example.
      The Helpfile specifies (a) WinHandle and (b) last Gui created.
      --> the example uses a control not a WinHandle and (b) what happens with ChildGuis? Also, the HelpFile specifies lower case, yet the examples show "{F1}" upper case?
      Also, is there a way to check the result of the GuiSetAccelerator function? 
      Note, if I add these to lines after the FOR loop, then the F1 works, and the DebugArrayDisplays shows control 4... not it's name... So I am in the right place, but my $vars names do not convert to their control numbers in the GUI
      Next $main__aAccelKeys[$sizeofHotkeys - 1][0] = "{F1}" ; -- -- use the extra row for the F1 $main__aAccelKeys[$sizeofHotkeys - 1][1] = $ChmHLP ;--- Skysnake
