Posted (edited)

This is a UDF called EzMySql for using a MySql database with autoit, it uses similar syntax as SQLite but for MySql, for a more comprehensive MySql UDF see MySQL UDF by ProgAndy.

Credit goes to ProgAndy as i used his UDF to be able to create this standalone UDF.

I have only been able to test it on windowsXP x32

Download EzMySql_Dll.au3

There are two scripts, EzMySql.au3 which contains the functions and EzMySql_Dll.au3 which has an embeded 32 and 64 dll.

The required dll will be created if it does not exist in the path given when calling _EzMySql_Startup,

if no path is given the dll will be created in the script directory.

Please give it a try and let me know of any problems/improvements:)

Example Script

#include "EzMySql.au3"
#include <Array.au3>

If Not _EzMySql_Startup() Then
    MsgBox(0, "Error Starting MySql", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())

    Exit
EndIf

If Not _EzMySql_SelectDB("EzMySqlTest") Then
    MsgBox(0, "Error setting Database to use", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())

    Exit
EndIf

$error = @error
If Not IsArray($aOk) Then MsgBox(0, $sMySqlStatement & " error", $error)

MsgBox(0, "", "Following is how to get a row at a time of a query as a 1d array")
If Not _EzMYSql_Query("SELECT * FROM TestTable WHERE HairColour = '"& $aHairColours[Random(0, 5, 1)] & "' LIMIT 5;") Then
MsgBox(0, "Query Error", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

For $i = 1 To _EzMySql_Rows() Step 1
    $a1Row = _EzMySql_FetchData()
    _ArrayDisplay($a1Row, "Result: " & $i)
Next

Nice ;)... I know it's an outdated-ish thread, but this is exactly what I need. Appears the other UDFs don't work anymore.

Any chance of a Column data retriever? I need all data from column in an array (array[0] amount of data, array[n] the data)

Thanks

Hello,

is the connection to a distant web DB is possible 

If Not _EzMySql_Open("myserver.net", "root", $Pass, "", "3306") Then
    MsgBox(0, "Error opening Database", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

If Not _EzMySql_Exec("CREATE DATABASE IF NOT EXISTS test_DB") Then
    MsgBox(0, "Error opening Database", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

If Not _EzMySql_SelectDB("_DB1") Then
    MsgBox(0, "Error setting Database to use", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

where can i sepcify the database name ? is 3306 the tcp port ?

how correctly do a connection to :

host : MyServer.net

Reekod,

did you manage to connect to your host? I'm still trying. Does anyone know how to connect to your host? Or any functions for this MySQL addition to AutoIt?

Thank you!

I'm trying to use _EzMySql_SelectDB() to verify that a database exists but it seems to always return 1 whether or not it's successful. A known bug?

; 1 - A MySQL struct does not exist

; 2 - Dll Open Call failed

; Author ........: Yoriz

; Based on script: MySQL UDFs working with libmysql.dll by Prog@ndy

Func _EzMySql_SelectDB($Database)

If Not $hEzMySql_Ptr Then Return SetError(1, 0, 0)

Local $conn = DllCall($hEzMySql_Dll, "int", "mysql_select_db", "ptr", $hEzMySql_Ptr, "str", $Database)

If @error Then Return SetError(2, 0, 1)

Return 1

Have some problem with charset, may be somebody can help me.

In my programm on my Cirilic PC i Use code like this:

_EzMySql_Startup()
  $mysqlconnect =  _EzMySql_Open($host,$user,$password,$database,$port)
  If $mysqlconnect = 0 Then
   MsgBox(0,"Error", "Can`t connect to database")
   Return 0
  EndIf
  _EzMySql_Query("SET NAMES cp1251")

And all cyrilic data is ok. New Inserted and Selected from DB to GUI.

But on Chines PC, i have a problem with charset, i cant see in GUI Cirilic data and can`t insert in DB Cyrilic data.

What "SET NAMES " i should use on chines pc

HKEY_CURRENT_USER\Control Panel\International\Locale = 00000804.

My database has charset and collation utf8_general_ci, and mysql server also utf8_general_ci at any parameter.

Was tryed any chinese charset but result was in my GUI " ??????????? "

Capturing the SQL error code

I am testing out trying to insert a duplicate using _EzMySql_Exec .

What I'm finding is that even though the code fails because it is trying to insert a duplicate it doesn't come back with an error and an SQL error message. ( looking at @error and & _EzMySql_ErrMsg().

Is there any way of capturing SQL errors that occur?

I use this UDF and needed to escape string. That I little rewrote this func (based on Prog@ndy UDF function) to use with EzMySql.au3

Func _EzMySql_Real_Escape_String($From, $FromLen = Default)
If Not $hEzMySql_Ptr Then
  MsgBox(0, "", "errer")
  Return SetError(1, 0, 0)
EndIf
If $FromLen <= 0 Or $FromLen = Default Then $FromLen = StringLen($From)
Local $TO = DllStructCreate("char[" & $FromLen * 2 + 1 & "]")
Local $query = DllCall($hEzMySql_Dll, "int", "mysql_real_escape_string", "ptr", $hEzMySql_Ptr, "ptr", DllStructGetPtr($TO), "str", $From, "ulong", $FromLen)
If @error Then Return SetError(1, 0, 0)
Return StringLeft(DllStructGetData($TO, 1), $query[0])

Hi guys,

I'm trying to set the connection to my DB,

I put my host, password, DB name and user to the _EzMySql_Open function.

That's all I did with it, now, when running the script I get all kinds of errors about "missing separator character after keyword".

Don't know exactly what it meens...

Anyone?

I realize this is a very old topic, but whenever I go to parse through my MySQL DB any text because a number - not the text..

 ;****************************************
 ; Get all Non-Active Articles
 ;****************************************
 If Not _EzMYSql_Query('SELECT * FROM rars_articles WHERE IsActive = 1;') Then
 MsgBox(0, 'Query Error', 'Error: ' & @error & @CR & 'Error string: ' & _EzMySql_ErrMsg())
  Exit
 Else
  For $i = 1 To _EzMySql_Rows() Step 1
   $a1Row = _EzMySql_FetchData()
   MsgBox (0, "ID ", $a1Row[0] + 0)
   MsgBox (0, "Date", $a1Row[1] + 0)
   MsgBox (0, "Section", $a1Row[2] + 0)
   MsgBox (0, "Title", $a1Row[3] + 0)
   MsgBox (0, "Author", $a1Row[4] + 0)
   ;_ArrayDisplay($a1Row, "Result: " & $i)
  Next
 EndIf

Where this should return a Text return for "Section", "Title", and "Author" it is returning 0 for each of those rows. Yet _ArrayDisplay displays them correctly:

What am I doing wrong, please?

   MsgBox (0, "Date", $a1Row[1] + 0)
   MsgBox (0, "Section", $a1Row[2] + 0)
   MsgBox (0, "Title", $a1Row[3] + 0)
   MsgBox (0, "Author", $a1Row[4] + 0)
   ;_ArrayDisplay($a1Row, "Result: " & $i)
  Next
 EndIf

Where this should return a Text return for "Section", "Title", and "Author" it is returning 0 for each of those rows. Yet _ArrayDisplay displays them correctly:

What am I doing wrong, please?

Have you tried without the "+ 0"? If you want to use that to alter the index you should put it inside the braquets ie MsgBox (0, "ID ", $a1Row[1 + 0]) although I don't know why you would want to do something like that since you already know what index you need.

Maybe you wanna add this to EzMySql.au3

Func _EzMySql_Real_Escape_String($From, $FromLen = Default)
   If Not $hEzMySql_Ptr Then Return SetError(1, 0, 0)

   If $FromLen <= 0 Or $FromLen = Default Then $FromLen = StringLen($From)

   Local $TO = DllStructCreate("char[" & $FromLen * 2 + 1 & "]")
   Local $query = DllCall($hEzMySql_Dll, "int", "mysql_real_escape_string", "ptr", $hEzMySql_Ptr, "ptr", DllStructGetPtr($TO), "str", $From, "ulong", $FromLen)
   If @error Then Return SetError(2, 0, 0)
   Return StringLeft(DllStructGetData($TO, 1), $query[0])
EndFunc

This function allow me to escape some strings before I send them in a query to MySQL.

I did copy this from ">MySQL UDFs (without ODBC)" and adapted it to EzMySql, it works for me but maybe the autor of EzMySql should take a look of it.

Good Luck.

I don't use MySQL but it looks like for security reasons Addcslashes() would be a better shield. Second remark: your code is going to translate native AutoIt Unicode strings into ANSI, which is probably not suitable for many users.

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.

In response to ChrisAnderson's Question. Try something like this. 

#include "EzMySql.au3"

$ipAddress = @IPAddress1

_EzMySql_Startup("\MYSQL")
$sqlConnect = _EzMySql_Open($ipAddress, "Username", "Password", "Database", 3306, "", 0) ;This opens a connection to the mysql database. Change Username Password and Database to YOUR mysql Database settings.

_EzMySql_Query('SELECT * FROM News') ;News is the table that I am getting data from. Change News to the name of the Table you want to query.
$myRows = _EzMySql_Rows() ;Just counts the rows that have data in them. 
_EzMySql_QueryFinalize()

$i = 1
$row = _EzMySql_GetTable2d('SELECT * FROM News') ;Makes a 2d array of data.
_EzMySql_QueryFinalize()

    Do
        MsgBox(0, "", $row[$i][1] & @CRLF & $row[$i][2])
    $i = $i + 1
     Until $i = $myRows + 1
_EzMySql_Close()

This works for me because I only have 2 fields of data. If you have a bunch of fields of data you would have to go much higher than two in the MsgBox. For example. 

Let's say I had 4 fields of Data. I would have to call the array like this:

MsgBox(0, "", $row[$i][1] & @CRLF & $row[$i][2] & @CRLF & $row[$i][3] & @CRLF & $row[$i][4])

This would display all 4 fields of information. This works because _EzMySql_GetTable2d() function makes a 2d array. You pull out the data from the array by using Column and Row. Column is number up and down. Row is number left and right. Which is why we call the variable $row like $row[1][1]. That says we are displaying data from Column1, Row1. Hopefully this helps anyone else struggling with this UDF as well.
