I'm trying to establish an ADO connection between excel on my local machine and a MySQL database on my server.
In the examples I've seen (here and here, for instance) there's a driver of the form MySQL ODBC 5.x Driver. It seems that after installing the latest mysql connector / odbc download (32-bit, to match my msexcel) the relevant registry driver files HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Driver\ are now named 'SQL Server' and 'SQL Server Native Client 11.0.' I'm not having success establishing a connection to MySQL with either of these.
My VBA
Sub connect()
Dim Password As String
Dim SQLStr As String
Dim Server_Name As String
Dim User_ID As String
Dim Database_Name As String
Set rs = CreateObject("ADODB.Recordset") 'EBGen-Daily
Server_Name = "184.154.225.243"
Database_Name = "*******" ' Name of database
User_ID = "********" 'id user or username
Password = "*******" 'Password
Port = "3306"
SQLStr = "SELECT * FROM *******"
Set Cn = CreateObject("ADODB.Connection")
Cn.Open "Driver={SQL Server};Server=" & _
Server_Name & ";Port=" & Port & ";Database=" & Database_Name & _
";Uid=" & User_ID & ";Pwd=" & Password & ";"
rs.Open SQLStr, Cn, adOpenStatic
Upon running the above, I receive error [Microsoft][ODBC SQL Server Drive][DBNETLIB]SQL Server does not exist or access denied. The error for the 'native client 11.0' driver is Could not open a connection to SQL Server[53].
I've tested the connection parameters in MySQL workbench and all is functional. What's going on?
Check if you are using the 32 bit or the 64 bit version of Microsoft Office.
Based on the above, download and install the appropriate MySQL driver from the download link
Once the ODBC driver installation is complete, check the ODBC snap in to see the driver is listed as installed.
If you are using a 32 bit OS, then everything is 32 bit. Use Run -> odbcad32.exe -> Drivers tab.
If you are using a 64 bit OS, and Microsoft Office is 32 bit, then use c:\windows\syswow64\odbcad32.exe -> Drivers tab.
If you are using a 64 bit OS, and Microsoft Office is 64 bit, then use Run -> odbcad32.exe -> Drivers tab.
If the MySQL drivers are properly installed, they should appear as shown above
Create a System DSN using the ODBC snap in with the MySQL driver listed above and test the connection to see if it works.
Use the same parameters when you try to create an ODBC from within VBA.
Example:
Driver={MySQL ODBC 5.3 ANSI Driver};Server=localhost;Database=myDataBase;
User=myUsername;Password=myPassword;Option=3;
Once it is established that you can successfully create a connection to the MySQL server, then change the driver name in the registry (make sure to update both the registry keys) and try using the new name you give such as SQL Server.
Remember: On a x64 bit system for a x32 bit drivers:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI\ODBC Drivers
A restart may be required after changing the driver name.

I'm trying to extract data from MySQL to Excel. I saw a lot of tutorials but I get the same error all the time.
Here is my code:
Sub consultdate()
Dim conn As New ADODB.Connection
Dim server_name As String
Dim database_name As String
Dim user_id As String
Dim password As String
Dim i As Long
Dim sqlstr As String
Dim table1 As String, table2 As String
Dim field1 As String, field2 As String
Dim rs As ADODB.Recordset
Dim vtype As Variant
server_name = "localhost"
database_name = "controle_fin"
user_id = "root"
password = "userpassword"
Set conn = New ADODB.Connection
conn.Open "DRIVER={MySQL ODBC 3.51 Driver}" _
& ";SERVER=" & server_name _
& ";DATABASE=" & database_name _
& ";UID=" & user_id _
& ";PWD=" & password _
& ";OPTION=16427"
table1 = "classe"
GoTo skipextract
Set rs = New ADODB.Recordset
sqlstr = "SELECT * FROM " & table1
rs.Open sqlstr, conn, adOpenStatic
Planilha1.Range("A1").CopyFromRecordset rs
skipextract:
On Error Resume Next
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
On Error GoTo 0
End Sub
Error that I got:
"ODBC Error. Data Source Name Not Found and No Default Driver Specified"
Typically, this error is due to the following reasons:
Simple Misspelling: ODBC driver names must be exactly spelled correctly and fully including special characters. To see all ODBC drivers, open up PowerShell window and type: Get-OdbcDriver | Format-Table name, platform -AutoSize to output a table similar to below:
name platform
---- --------
Microsoft Access Driver (*.mdb) 32-bit
Microsoft dBase Driver (*.dbf) 32-bit
Microsoft Excel Driver (*.xls) 32-bit
Microsoft ODBC for Oracle 32-bit
SQL Server 32-bit
SQL Server Native Client 11.0 32-bit
ODBC Driver 13 for SQL Server 32-bit
SQL Server 64-bit
Microsoft Access Driver (*.mdb, *.accdb) 64-bit
Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb) 64-bit
Microsoft Access Text Driver (*.txt, *.csv) 64-bit
SQL Server Native Client 11.0 64-bit
PostgreSQL ANSI(x64) 64-bit
PostgreSQL Unicode(x64) 64-bit
ODBC Driver 13 for SQL Server 64-bit
Microsoft Access dBASE Driver (*.dbf, *.ndx, *.mdx) 64-bit
...
Incompatible 32/64 bit architectures: Whatever ODBC driver you connect to must maintain same bit architecture as your MS Office version. If you run 32-bit Office, only 32-bit drivers are available (indicated under platform in step 1 output). Similarly goes for 64-bit. To verify which Office bit version you have installed on Windows and Mac, see here.
Permissions issue: While drivers are available, they may not be accessible to current user or group at file and/or folder level. This tends to be more an issue on *Unix systems (Linux/Mac) and not Windows which requires chmod or chown handling. For Windows, adjust properties of file or folder in Explorer for read/write/execute permissions.
In Excel-VBA We used to have a sql database connection using MySQL drivers. Since this wasn't working for everyone we decided to install MariaDB drivers at every pc and use these drivers. The speed of opening an connection however, has decreased dramatically. Here is the code of the new and old vba script.
p_dbConn.ConnectionString = _
"DRIVER={MariaDB ODBC 2.0 Driver};" & _
"SERVER=xx;" & _
"DATABASE=xx;" & _
"UID=xx;PASSWORD=xx;OPTION=3"
p_dbConn.Open
p_dbConn.ConnectionString = _
"DRIVER={MySQL ODBC 5.3 ANSI Driver};" & _
"SERVER=xx;" & _
"DATABASE=xx;" & _
"UID=xx;PASSWORD=xx;OPTION=3"
p_dbConn.Open
I ran the script in debug mode and the .open statement takes way longer with the mariadb driver. Anyone has any idea why?
Thanks!
I know it's not the driver that you are using ... but I use the following connection in my VBA code to connect to SQL Servers:
Reference File: Microsoft DAO 3.6 Object Library
'*************************************
'* SQL Server database connection *
'*************************************
Dim db As ADODB.Connection
Set db = New ADODB.Connection
db.Open "Provider=sqloledb; Data Source = 192.168.0.10; Database = [your DB Name];User Id = xxxxxx; Password = xxxxxxxx"
if a command takes longer than 45 seconds to execute ... use this to extend the execution default time
db.CommandTimeout = 1200 '(1200/60 = 20 minutes)
Sample Simple Commands
Set rst = db.execute("Select * from [your table name]")
db.execute("Delete from [your table name] where [your criteria]")
I'm trying to connect to a MySQL database from within a VBS script, but I can't get passes a specific error -
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
I'm running 64-bit Windows 7 (from where the script is running), and the MySQL DB is running on 32-bit Linux. I've tried both the 32- and 64-bit drivers on Windows 7, downloaded from the Download Connector/ODBC page on the MySQL website, but the error persists.
I have found a couple of pages about this issue (including this one), but I've been unable to resolve my issue. How can I make the DB connection I require?
Dim Connection : Set Connection = CreateObject("ADODB.Connection")
Dim RS : Set RS = CreateObject("ADODB.Recordset")
Dim dbConStr : dbConStr = "Driver={MySQL ODBC 5.3.6 Driver};Server=https://mysqlserver.mydomain.com;Data Source=dsn_hb; Database=MyDatabase; User=MyUser; Password=MyPassword;"
Connection.Open dbConStr
RS.open "SELECT * FROM apklibrary.djg_local_archive_scans", Connection, 3
RS.MoveFirst
While Not RS.EOF
Call MsgBox (RS.Fields(0), vbOkOnly, "POW!")
RS.MoveNext
Wend
Connection.close
Set Connection = Nothing
Set RS = Nothing
Call MsgBox ("No more records to show you.", vbOkOnly, "Job done")
The specified driver name is invalid. Valid MyODBC 5.3 driver names:
{MySQL ODBC 5.3 ANSI Driver}
{MySQL ODBC 5.3 Unicode Driver}
Another problem is Server. You should specify the server's address without https://.
Also, since you have user name and password Data Source=dsn_hb; looks redundant, remove it. If not please give us more detail.
So, give a try this:
dbConStr = "DRIVER={MySQL ODBC 5.3 Unicode Driver};Server=mysqlserver.mydomain.com;Database=MyDatabase;User=MyUser;Password=MyPassword;"
I have access to a database on a remote mySQL server. I can read the data from my local mySQL workbench. I can also link to, and read, its tables using MS Access.
I have tried to use the following code in VB6 but are unable to establish a connection -
Set DBCon = New ADODB.Connection
DBCon.CursorLocation = adUseClient
DBCon.Open "Driver={MySQL ODBC 5.1 Driver}; Server=sherwood.unitingchurch.org.au;port=3306; Database=UCSData;User=UCS;Password=" & Pwd & ";Option=3;"
I have a copy of the mySQL database on my local computer and the VB6 program can see and use the data without problems, using the same code (but with localhost as the server).
Set DBCon = New ADODB.Connection
DBCon.CursorLocation = adUseClient
DBCon.Open "Driver={MySQL ODBC 5.1 Driver};Server=localhost; port=3306;Database=UCSData; User=UCS; Password=" & Pwd & ";Option=3;"
Any help would be appreciated.
What is the error message?
I think your problem has to do with the driver.
Which architecture(32 or 64 bits) is your Windows,Office?
i am using the OBDC connector to use VBA to connect to my MySQL database. It currently runs on a local webserver (localhost) but is accessible from other PCs on the network via my PC's IP address.
In my connection function I had localhost as the location but when I change it to my IP address I get an
[MySQL][ODBC 5.2 Driver] (my computer name) is not allowed to connect to this MySQL server
error.
I presume this is a security problem. Any way to fix this?
Here is my connection function:
Public Function OpenConnection() As ADODB.connection
//This function requires the "Microsoft ActiveX Data Objects" Library (Choose v2.8 from references for compatibility across Office versions)
Dim source As String, location As String, user As String, password As String
source = "MySQL"
location = "192.168.1.60"
user = "root"
password = ""
database = "database name"
mysql_driver = "MySQL ODBC 5.2 ANSI Driver"
//Build the connection string
Dim connectionString As String
connectionString = "Driver={" & mysql_driver & "};Server=" & location & ";Database=" & database & ";UID=" & user & ";PWD=" & password
//Create and open a new connection to the selected source
Set OpenConnection = New ADODB.connection
OpenConnection.CursorLocation = adUseClient
Call OpenConnection.Open(connectionString)
End Function
You need to modify the user account in MySQL. It is possible to modify the locations users are allowed to connect from and their credentials. Look at this post:
Allow all remote connections, MySQL
