Exporting Data from Excel to phpmyadmin SQL database - mysql

I would appreciate some help solving problems accessing a MySQL database from Excel.
I've created the database in phpmyadmin. I've also been able to manually import data via a CSV file into the SQL database on phhpmyadmin.
So, I'm sure that I've got the right IP address, user ID and password for the database.
I've also read various posts about how to configure ODBC connections from Windows to SQL and I think I've followed the right instructions.
However, I can't seem to get the code to work from VBA. I keep getting various errors.
Here's the code I've been using, minus the actual database names and User IDs.
Private Sub cmdInsertData_Click()
Dim oConn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim Pwd As String
Dim SQLStr As String
Dim Svr_Nm As String
Dim UID As String
Dim Dbs_Nm As String
' Input Parameters
Pwd = "mypassword"
UID = "myuser"
srvr_nm = "xxx.xxx.xx.xx:yyyy"
Dbs_Nm = "myname"
Set rs = New ADODB.Recordset
Set oConn = New ADODB.Connection
SQLStr = "DRIVER={MySQL ODBC 5.3 ANSI Driver};"
SQLStr = SQLStr & "SERVER=" & srvr_nm & ";DATABASE=" & Dbs_Nm & ";USER=" & UID & ";PASSWORD=" & Pwd & ";Option=3"
oConn.Open SQLStr
MsgBox "Connected to " & Dbs_Nm & " via " & srvr_nm
End Sub
I've reset the code as follows. The error message is generated by the line "oConn.Open SQLStr". The error generated is
Run-time error ‘-2147467259 (80004005)’:
[MySQL][ODBC 5.3(a) Driver]Unknown MySQL server host ‘209.159.152.202:2083’ (0)
New Code:
Private Sub CheckConnection()
Dim oConn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim Pwd As String
Dim SQLStr As String
Dim Svr_Nm As String
Dim Usr_ID As String
Dim Dbs_Nm As String
' Input Parameters
Pwd = "mypassword"
Usr_ID = "myID"
srvr_nm = "209.159.152.202:2083"
Dbs_Nm = "mydatabase"
Set rs = New ADODB.Recordset
Set oConn = New ADODB.Connection
SQLStr = "DRIVER={MySQL ODBC 5.3 ANSI Driver};"
SQLStr = SQLStr & "SERVER=" & srvr_nm & ";DATABASE=" & Dbs_Nm & ";USER=" & Usr_ID & ";PASSWORD=" & Pwd & ";Option=3"
oConn.Open SQLStr
MsgBox "Connected to " & Dbs_Nm & " via " & srvr_nm
End Sub
Thanks for the suggestion about adding the Port= as a separate variable. I've tried that however (see new code) and it still doesn't work.
Private Sub CheckConnection()
Dim oConn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim Pwd As String
Dim SQLStr As String
Dim Svr_Nm As String
Dim Usr_ID As String
Dim Dbs_Nm As String
Dim Port_Nm As String
' Input Parameters
Pwd = "mypassword"
Usr_ID = "myID"
Svr_Nm = "209.159.152.202"
Dbs_Nm = "mydatabase"
Port_Nm = "2083"
Set rs = New ADODB.Recordset
Set oConn = New ADODB.Connection
SQLStr = "DRIVER={MySQL ODBC 5.3 ANSI Driver};"
SQLStr = SQLStr & "Server=" & Svr_Nm & ";Port=" & Port_Nm & ";Database=" & Dbs_Nm & ";User=" & Usr_ID & ";Password=" & Pwd & ";Option=3"
oConn.Open SQLStr
MsgBox "Connected to: " & Dbs_Nm & " via " & Svr_Nm
End Sub
I still get the same error message at the same place.

I have validated the connection is working. I can query data by opening the connection and executing SQL.
I am unable to create a linked table programmatically in Access using visual basic for applications with the created connection.
Has anyone been able to successfully create a linked dsn-less table from Access to Teradata?
If you have a working ODBC connection string then you should be able to use DoCmd.TransferDatabase to create a linked table. I don't have a Teradata server handy, but this works for me with SQL Server:
Dim connStr As String
connStr = _
"DRIVER=ODBC Driver 11 for SQL Server;" & _
"SERVER=(local)\SQLEXPRESS;" & _
"DATABASE=myDb;" & _
"Trusted_Connection=yes"
DoCmd.TransferDatabase _
TransferType:=acLink, _
DatabaseType:="ODBC Database", _
DatabaseName:="ODBC;" & connStr, _
ObjectType:=acTable, _
Source:="dbo.projects", _
Destination:="dbo_projects"
I eventually found a connection string that works! :)
Function adoTera()
Dim oConn As ADODB.Connection
Dim rs As ADODB.Recordset
Set oConn = New ADODB.Connection
Set rs = New ADODB.Recordset
oConn.ConnectionString = "PROVIDER=MSDASQL;" & _
"DRIVER={Teradata};" & _
"DBCName=yourDBCName;" & _
"DefaultDatabase=yourDBName;" & _
"UID=yourUserName;" & _
"PWD=yourPassword;"
oConn.Open
rs.Open "SELECT * FROM yourTable", oConn
ThisWorkbook.Worksheets("Sheet1").Range("A:A").CopyFromRecordset rs
rs.Close
oConn.Close
Set rs = Nothing
Set con = Nothing

open ADO recordset as visible table

I'm doing something like this for the first time and it seems incredibly hard to find any useful information at all.
What I want to do:
Pass a select-query to a MySQL database and show the result in a table.
I've got that far by now: I have a button on a form and when clicked the following happens
Option Compare Database
Sub RunPassThrough(strSQL As String)
Dim ConnectionString As String
Dim Server As String
Dim User As String
Dim Pwd As String
Dim DatabaseName As String
Dim Cn As ADODB.Connection
Dim Rs As ADODB.Recordset
' Server Hostname (or IP)
Server = "192.168.178.10"
User = "user"
Pwd = "mypass"
DatabaseName = "myDB"
ConnectionString = "Provider=MSDASQL;Driver={MYSQL ODBC 5.1 DRIVER};" & _
"Server=" & Server & ";Database=" & DatabaseName
Set Cn = New ADODB.Connection
Cn.CursorLocation = adUseClient
Cn.Mode = adModeShareDenyNone
Cn.Open ConnectionString, User, Pwd
Set Rs = New ADODB.Recordset
Rs.Open strSQL, Cn, adOpenDynamic, adLockReadOnly
'Set Rs = Cn.Execute("select * from SurveyResults limit 10;")
End Sub
Private Sub Befehl0_Click()
Dim SQL As String
SQL = "select * from SurveyResults limit 10;"
RunPassThrough (SQL)
End Sub
I know that Rs.Open strSQL, Cn, adOpenDynamic, adLockReadOnly returns an ADO recordset and I could do things with it using VBA, but all I want is to show that recorod set to the user in table.
something like OpenRecordset("Rs", as a table that the user can see)
can someone please point me into the right direction I'm going crazy...
I figured it out. My problem was simply that the ReturnsRecords Property is set to false by default.
it works now, so I'm posting a answer if anyone ever needs it.
Sub RunPassThrough(strSQL As String)
Dim Server As String
Dim User As String
Dim Pwd As String
Dim DatabaseName As String
Dim qdfPassThrough As DAO.QueryDef, MyDB As Database
Dim strConnect As String
' Server Hostname (or IP)
Server = "192.168.178.10"
User = "user"
Pwd = "mypass"
DatabaseName = "database"
For Each qdf In CurrentDb.QueryDefs
If qdf.Name = "PassQuery" Then
CurrentDb.QueryDefs.Delete "PassQuery"
Exit For
End If
Next
strConnect = "ODBC;DRIVER={MYSQL ODBC 5.1 DRIVER};SERVER=" & Server & ";DATABASE=" & DatabaseName & ";Uid=" & User & ";Pwd=" & Pwd & ";"
Set MyDB = CurrentDb()
Set qdfPassThrough = MyDB.CreateQueryDef("PassQuery")
qdfPassThrough.Connect = strConnect
qdfPassThrough.SQL = strSQL
qdfPassThrough.Close
Application.RefreshDatabaseWindow
MyDB.QueryDefs("PassQuery").ReturnsRecords = True
DoCmd.OpenQuery "PassQuery", acViewNormal, acReadOnly
DoCmd.Maximize
End Sub

Trying to extract data from MySQL to Excel using VBA

I am getting an error and I don't understand what is the problem. Here is my code
Sub test()
Dim rs As ADODB.Recordset
Dim sqlstr As String ' SQL to perform various actions
Dim oConn As ADODB.Connection
Set oConn = New ADODB.Connection
oConn.Open "DRIVER={MySQL ODBC 5.3 Unicode Driver};" & _
"SERVER=ETS-DEV-01;" & _
"DATABASE=reporting;" & _
"USER=guest_user;" & _
"PASSWORD=0X4ZT9kwsY%yGOp;" & _
"Option=3"
sqlstr = "select * from tveuptimes"
rs.Open sqlstr, oConn
End Sub
I am getting the error:
Run-time error '91'
Object variable or with block variable not set.
I don't understand what i am doing wrong.
The line Set oConn = New ADODB.Connection isn't necessary. Instead, when you dimension rs and oConn add the word New before the type, like this:
Sub test()
Dim rs As New ADODB.Recordset
Dim sqlstr As String
Dim oConn As New ADODB.Connection
oConn.Open "DRIVER={MySQL ODBC 5.3 Unicode Driver};" & _
"SERVER=ETS-DEV-01;" & _
"DATABASE=reporting;" & _
"USER=guest_user;" & _
"PASSWORD=0X4ZT9kwsY%yGOp;" & _
"Option=3"
sqlstr = "select * from tveuptimes"
rs.Open sqlstr, oConn
End Sub

How can VBA connect to MySQL database in Excel?

Dim oConn As ADODB.Connection
Private Sub ConnectDB()
Set oConn = New ADODB.Connection
Dim str As String
str = "DRIVER={MySQL ODBC 5.2.2 Driver};" & _
"SERVER=sql100.xtreemhost.com;" & _
"PORT=3306" & _
"DATABASE=xth_9595110_MyNotes;" & _
"UID=xth_9595110;" & _
"PWD=myPassword;" & _
"Option=3"
''' error '''
oConn.Open str
End Sub
Private Sub InsertData()
Dim rs As ADODB.Recordset
Set rs = New ADODB.Recordset
ConnectDB
sql = "SELECT * FROM ComputingNotesTable"
rs.Open sql, oConn, adOpenDynamic, adLockOptimistic
Do Until rs.EOF
Range("A1").Select
ActiveCell = rs.Fields("Headings")
rs.MoveNext
Loop
rs.Close
oConn.Close
Set oConn = Nothing
Set rs = Nothing
End Sub
Doing the similar things in PHP, I could successfully log in to the MySQL server.
I have installed the ODBC connector.
But in the above VBA codes, I failed.
An error turns up. (see the codes where the error exists)
$connect = mysql_connect("sql100.xtreemhost.com","xth_9595110","myPassword") or die(mysql_error());
mysql_select_db("myTable",$connect);
This piece of vba worked for me:
Sub connect()
Dim Password As String
Dim SQLStr As String
'OMIT Dim Cn statement
Dim Server_Name As String
Dim User_ID As String
Dim Database_Name As String
'OMIT Dim rs statement
Set rs = CreateObject("ADODB.Recordset") 'EBGen-Daily
Server_Name = Range("b2").Value
Database_name = Range("b3").Value ' Name of database
User_ID = Range("b4").Value 'id user or username
Password = Range("b5").Value 'Password
SQLStr = "SELECT * FROM ComputingNotesTable"
Set Cn = CreateObject("ADODB.Connection") 'NEW STATEMENT
Cn.Open "Driver={MySQL ODBC 5.2.2 Driver};Server=" & _
Server_Name & ";Database=" & Database_Name & _
";Uid=" & User_ID & ";Pwd=" & Password & ";"
rs.Open SQLStr, Cn, adOpenStatic
Dim myArray()
myArray = rs.GetRows()
kolumner = UBound(myArray, 1)
rader = UBound(myArray, 2)
For K = 0 To kolumner ' Using For loop data are displayed
Range("a5").Offset(0, K).Value = rs.Fields(K).Name
For R = 0 To rader
Range("A5").Offset(R + 1, K).Value = myArray(K, R)
Next
Next
rs.Close
Set rs = Nothing
Cn.Close
Set Cn = Nothing
End Sub
Ranjit's code caused the same error message as reported by Tin, but worked after updating Cn.open with the ODBC driver I'm running. Check the Drivers tab in the ODBC Data Source Administrator. Mine said "MySQL ODBC 5.3 Unicode Driver" so I updated accordingly.
Just a side note for anyone that stumbles onto this same inquiry... My Operating System is 64 bit - so of course I downloaded the 64 bit MySQL driver... however, my Office applications are 32 bit... Once I downloaded the 32 bit version, the error went away and I could move forward.
Updating this topic with a more recent answer, solution that worked for me with version 8.0 of MySQL Connector/ODBC (downloaded at https://downloads.mysql.com/archives/c-odbc/):
Public oConn As ADODB.Connection
Sub MySqlInit()
If oConn Is Nothing Then
Dim str As String
str = "Driver={MySQL ODBC 8.0 Unicode Driver};SERVER=xxxxx;DATABASE=xxxxx;PORT=3306;UID=xxxxx;PWD=xxxxx;"
Set oConn = New ADODB.Connection
oConn.Open str
End If
End Sub
The most important thing on this matter is to check the proper name and version of the installed driver at:
HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBCINST.INI\ODBC Drivers\
Enable Microsoft ActiveX Data Objects 2.8 Library
Dim oConn As ADODB.Connection
Private Sub ConnectDB()
Set oConn = New ADODB.Connection
oConn.Open "DRIVER={MySQL ODBC 5.1 Driver};" & _
"SERVER=localhost;" & _
"DATABASE=yourdatabase;" & _
"USER=yourdbusername;" & _
"PASSWORD=yourdbpassword;" & _
"Option=3"
End Sub
There rest is here: http://www.heritage-tech.net/908/inserting-data-into-mysql-from-excel-using-vba/
Just to update this further
instead of looping through every row and column which takes forever.
try using
`Sub connect()
Dim Password As String
Dim SQLStr As String
'OMIT Dim Cn statement
Dim Server_Name As String
Dim User_ID As String
Dim Database_Name As String
'OMIT Dim rs statement
Set rs = CreateObject("ADODB.Recordset") 'EBGen-Daily
Server_Name = "Server_Name "
Database_Name = "Database_Name" ' Name of database
User_ID = "User_ID" 'id user or username
Password = "Password" 'Password
SQLStr = "SELECT * FROM item"
Set Cn = CreateObject("ADODB.Connection") 'NEW STATEMENT
Cn.Open "Driver={MySQL ODBC 8.0 ANSI Driver};Server=" & _
Server_Name & ";Database=" & Database_Name & _
";Uid=" & User_ID & ";Pwd=" & Password & ";"
rs.Open SQLStr, Cn, adOpenStatic
Range("A2").CopyFromRecordset rs
rs.Close
Set rs = Nothing
Cn.Close
Set Cn = Nothing
End Sub
this is multiple minutes faster
