My requirement: To search for data in database, using VB forms and 3 text boxes.
1 TextBox, I will give Input (UserName)
1 TextBox for Location
1 TextBox for displaying output
My code is
Private Sub CommandButton3_Click()
Dim Cn As ADODB.Connection '* Connection String
Dim oCm As ADODB.Command '* Command Object
Dim sName As String
Dim rs As ADODB.Recordset
Dim uname As String
Set Cn = New ADODB.Connection
Cn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=d:\test2.accdb;Persist Security Info=False"
Cn.ConnectionTimeout = 40
Cn.Open
Set oCm = New ADODB.Command
oCm.ActiveConnection = Cn
‘Record Set
Set rs = New ADODB.Recordset
‘Select Operation
rs.Open "SampleTable", Cn, adOpenKeyset, adLockPessimistic, adCmdTable
uname = rs("UserName")
rs.Open "Select * from SampleTable where uname = '" & text1.Text & "'", ActiveConnection, adOpenForwardOnly, adLockReadOnly, adCmdText
**'Display the Output in TextBox3**
TextBox3.Text = rs("UserName") + rs("Location")
rs.Close
Cn.Close
End Sub
I can understand the population of data is not happening so getting a RunTime error 424 at Select statement. How can I retrieve the data for the corresponding Input given?
You do not need to open the table; rs.Open "SampleTable" before searching it.
Not sure what this is for; uname = rs("UserName")
You should just run; rs.Open "Select * ... (Running the .Open on the same RS twice without closing the first is probably whats causing your error)
You should escape your input; replace$(text1.Text, "'", "''")
You should check for rs.EOF after the .open
Use & not + for concatenating strings
update
sub xxx
Dim Cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim sName As String
Set Cn = New ADODB.Connection
Cn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=d:\test2.accdb;Persist Security Info=False"
Cn.ConnectionTimeout = 40
Cn.Open
Set rs = New ADODB.Recordset
sName = replace$(text1.Text, "'", "''")
rs.Open "Select * from SampleTable where UserName = '" & sName & "'", Cn, adOpenForwardOnly, adLockReadOnly, adCmdText
if (rs.eof) then
msgbox "no match"
else
TextBox3.Text = rs("UserName") & " " & rs("Location")
rs.Close
end if
set rs = nothing
Cn.Close
set cn = nothing

Getting this error all time:
Run-time error '13': Type mismatch.
On this line
rs.Open , sqlstr, conn
I tried everything and can't solve the problem. I'm trying to update one row in MySQL database.
Private Sub CommandButton3_Click()
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 = "99.99.99.99"
database_name = "name"
user_id = "user"
password = "pass"
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"
Set rs = New ADODB.Recordset
sqlstr = "SET SQL_SAFE_UPDATES = 0; UPDATE table SET poslano = 'Poslano' WHERE poslano = 'Neposlano';"
rs.Open , sqlstr, conn
With Worksheets("List6").Cells("A1")
.ClearContents
.CopyFromRecordset rs
End With
skipextract:
On Error Resume Next
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing
On Error GoTo 0
End Sub
The comma after rs.Open makes VBA "think" that the Source is omitted:
Thus, it gives Type mismatch error. Try to write it like this:
rs.Open sqlstr, conn
I have a really weird issue with my Excel VBA code selecting values from a MySQL database. I structured a simple database with following columns:
ID
Name
Surname
City
And lets assume having following entrys:
01; Pan; Peter; NYC
02; P; Peter; NYC
But now the issue, if I select * from my table it shows me only following output:
01; P; Pan; NYC
02; P; Pan; NYC
That means the I only see the minimal lenght of an entry .... what is going on there? I have really casual VBA code in different modules for that task:
Public variables:
Public cn As ADODB.Connection
Public rs As ADODB.Recordset
Public strSql As String
Connection module:
Public Function connectDB()
Dim strServer_Name As String
Dim strDB_Name As String
Dim strUser_ID As String
Dim strPassword As String
With Sheet2
strServer_Name = .Range("B2").Value
strDB_Name = .Range("B3").Value
strUser_ID = .Range("B4").Value
strPassword = .Range("B5").Value
End With
Set cn = New ADODB.Connection
cn.Open "DRIVER={MySQL ODBC 5.3 Unicode Driver}" & _
";SERVER=" & strServer_Name & _
";DATABASE=" & strDB_Name & _
";UID=" & strUser_ID & _
";PWD=" & strPassword & ""
End Function
Sub module:
Sub request()
strSql = "SELECT * FROM test"
Call connectDB
Set rs = New ADODB.Recordset
rs.Open strSql, cn, adOpenDynamic
With Sheet1.Range("A1")
.ClearContents
.CopyFromRecordset rs
End With
Call disconnectDB
End Sub
Is this a VBA issue or are there any bugs in my MySQL?
Okay guys I've found a solution in this post: sql-query-doesnt-return-full-results-for-only-one-field
Solved it the same way the other guy did. In my code it looks like this:
Sub request()
Dim iCols As Integer
Dim iRows As Integer
strSql = "SELECT * FROM test"
Call connectDB
Set rs = New ADODB.Recordset
rs.Open strSql, cn, adOpenDynamic
iRows = 10
While Not rs.EOF
For iCols = 0 To rs.Fields.Count - 1
Tabelle1.Cells(iRows, iCols + 1).Value = rs.Fields(iCols).Value
Next
rs.MoveNext
iRows = iRows + 1
Wend
Call disconnectDB
End Sub
But thanks to everyone who tried to help me!
I've create an excel userform to collect data. I have connected it to Access to dump the data. However I want to update Access every time a user presses the submit button.
Basically I need the Select statement to determine an id existence, then if it doesn't exists I need to use the INSERT to add the new row. I'm very new with any SQL so any help would be great.
Here is the code I have now, I need to adapt it to ADO.
Sub Update()
Dim cnn As ADODB.Connection
Dim MyConn
Dim rst As ADODB.Recordset
Dim StrSql As String
Set cnn = New ADODB.Connection
MyConn = ThisWorkbook.Path & Application.PathSeparator & TARGET_DB
With cnn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.Open MyConn
Set rst = New ADODB.Recordset
rst.CursorLocation = adUseServer
rst.Open Source:="Foam", ActiveConnection:=cnn, _
CursorType:=adOpenDynamic, LockType:=adLockOptimistic, _
Options:=adCmdTable
StrSql = "SELECT * FROM Foam WHERE FoamID = " & txtMyID
Set rst = CurrentDb.OpenRecordset(StrSql, dbOpenDynaset)
If (rst.RecordCount = 0) Then
DoCmd.RunSQL "INSERT INTO Foam (ID, Part, Job, Emp, Weight, Oven) VALUES " & _
"(" & txtID & ", '" & txtField1 & "', '" & txtField2 & "', '" & txtField3 & "', '" & txtField4 & "', '" & txtField5 & "' );"
End If
' Close the connection
rst.Close
cnn.Close
Set rst = Nothing
Set cnn = Nothing
End With
End Sub
I revised your code sample just enough to get it working on my system and tested this version in Excel 2007.
When I use a value for lngId which matches the id of an existing record, that record is opened in the recordset and I can update the values of its fields.
When lngId does not match the id of an existing record, the recordset opens empty [(.BOF And .EOF) = True]. In that situation, I add a new record and add the field values to it.
Sub Update()
Const TARGET_DB As String = "database1.mdb"
Dim cnn As ADODB.Connection
Dim MyConn As String
Dim rst As ADODB.Recordset
Dim StrSql As String
Dim lngId As Long
Set cnn = New ADODB.Connection
MyConn = ThisWorkbook.Path & Application.PathSeparator & TARGET_DB
With cnn
.Provider = "Microsoft.ACE.OLEDB.12.0"
.Open MyConn
End With
lngId = 4
StrSql = "SELECT * FROM tblFoo WHERE id = " & lngId
Set rst = New ADODB.Recordset
With rst
.CursorLocation = adUseServer
.Open Source:=StrSql, ActiveConnection:=cnn, _
CursorType:=adOpenDynamic, LockType:=adLockOptimistic, _
Options:=adCmdText
If (.BOF And .EOF) Then
' no match found; add new record
.AddNew
!ID = lngId
!some_text = "Hello World"
Else
' matching record found; update it
!some_text = "Hello World"
End If
.Update
.Close
End With
Set rst = Nothing
cnn.Close
Set cnn = Nothing
End Sub
Using VBA, here is a sample of how to query for a certain ID to check if it exists. If it does not then add it via an INSERT statement:
Dim rs As DAO.Recordset
Dim StrSql As String
StrSql = "SELECT * FROM MyTable WHERE ID = " & txtMyID
Set rs = CurrentDb.OpenRecordset(StrSql, dbOpenDynaset)
If (rs.RecordCount = 0) Then
DoCmd.RunSQL "INSERT INTO MyTable (ID, Field1, Field2) VALUES " & _
"(" & txtID & ", '" & txtField1 & "', '" & txtField2 & "');"
End If
I Have created a ODBC DSN to MySQL called "TEST". The table in the MySQL Database is Called "DETAILS" and the columns are called:
ID (Auto Number) | NAME | SURNAME | DATE|
In Excel, I have a userform with the following controls: Textbox1 = NAME, Textbox2 = SURNAME and DTPicker = DATE + a Command Button Called SAVE.
Is there a way that I can save this data directly to the MySQL Database by pushing the command button? I have the ODBC DSN connection to access the database
UPDATE
This is the code I Have:
Private Sub CommandButton1_Click()
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
strCon = "Driver={MySQL ODBC 5.1 Driver};SERVER=SERVERNAME;DATABASE=DATABASE;UID=USERID;PWD=PASSWORD"
Set cn = CreateObject("ADODB.Connection")
cn.Open strCon
Set rs = CreateObject("adodb.recordset")
rs.Open "INSERT INTO MYTABLE (ID, Name, Surname, Date) VALUES (Textbox1.Value, Textbox2.value, DTPicker1.Value)", cn
rs.Close
End Sub
But It doesn't allow me to reference the CONTROLS, Textboxes and DTPicker
Give this a shot:
Private Sub CommandButton1_Click()
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
strCon = "Driver={MySQL ODBC 5.1 Driver};SERVER=SERVERNAME;DATABASE=DATABASE;UID=USERID;PWD=PASSWORD"
Set cn = CreateObject("ADODB.Connection")
cn.Open strCon
Set rs = CreateObject("adodb.recordset")
rs.Open "INSERT INTO MYTABLE (Name, Surname, Date)" _
" VALUES (" & Textbox1.Value & ", " & Textbox2.value _
", " & DTPicker1.Value &")", cn
rs.Close
End Sub
Here is the Code to Make this work:
Private Sub CommandButton1_Click()
Dim c As ADODB.Connection
Dim r As ADODB.Recordset
Set c = New ADODB.Connection
Dim rw As Integer
c.Open "DSN=DSNName"
sq = "Insert into MYTABLE (NAME, SURNAME, DATE) values ('" & TextBox1.Value & "','" & TextBox2.Value & "','" & DTPicker1.Value & "')" Set r = c.Execute(sq)
c.Close
End Sub
Access Database Form1 is a Continuous Form that has an EmployeeID field you can double click to take you to another form that contains information about the Employee. In order to retain the correct employee I use this code...
Private Sub EmployeeID_DblClick(cancel as integer)
Dim myID as variant
myID = me.EmployeeID
DoCmd.OpenForm "frm_EmployeeInfo",,,,,,myID
End Sub
This Not only brings up the correct employee information but populates the number into a hidden textbox to retain the information.
On the Employee Form there is a TabControl with 4 tabs, one of the tabs contains a Continous subform that I am trying to populate employee information but instead of the information being populated down (let's say Employee X has 8 lines of different attributes to display) it is repeating the same one. Here is my code for the subform:
Option Compare Database
Private Sub Form_open(cancel As Integer)
Dim strConnection, strSQL As String
Dim conn As ADODB.Connection
Dim tbl As ADODB.Recordset
Dim SourceCode As String
Dim myID As Variant
Set conn = New ADODB.Connection
strConnection = "ODBC;Driver={SQLserver};DSN=AccessDatabase;Server=Labor;DATABASE=Source;Trusted_Connection=Yes;"
conn.Open strConnection
myID = CInt(Me.OpenArgs)
SourceCode= Nz(DLookup("[SourceCode]", "Locaton", "[LOC_ID] = Forms!frmUtility![Site].value"), "")
If SourceCode<> "" Then
strSQL = "SELECT EmployeeID,BenefitID,DeductionAmount,BenefitAmount,CoverageAmount,EffectiveDate,"
strSQL = strSQL & "EligibleDate,ExpirationDate FROM "
strSQL = strSQL & SourceCode & "_EmployeesBenefitsNew WHERE EmployeeID= " & myID
Else
strSQL = "SELECT EmployeeID,BenefitID,DeductionAmount,BenefitAmount,CoverageAmount,EffectiveDate,"
strSQL = strSQL & "EligibleDate,ExpirationDate FROM "
strSQL = strSQL & "EmployeesBenefitsNew WHERE EmployeeID= " & myID
End If
Set tbl = New ADODB.Recordset
With tbl
Set .ActiveConnection = conn
.Source = strSQL
.LockType = adLockOptimistic
.CursorType = adOpenKeyset
.CursorLocation = adUseClient
.Open
End With
With tbl
On Error Resume Next
.MoveFirst
Do Until tbl.EOF
Me.txtBenefitID.Value = tbl!BenefitID
Me.txtDeductionAmt.Value = tbl!DeductionAmount
Me.txtBenefitAmt.Value = tbl!BenefitAmount
Me.txtCoverageAmt.Value = tbl!CoverageAmount
Me.txtEffDt.Value = tbl!EffectiveDate
Me.txtTermDt.Value = tbl!ExpirationDate
Set Me.Recordset = tbl
.MoveNext
Loop
.Close
End With
conn.Close
Set conn = Nothing
Set tbl = Nothing
End Sub
Can anyone shed some light on this situation? Thanks!
You need to either set the recordset or the recordsource with the data, you cannot write to a continuous form on different lines, the lines only display as different if you have a recordset.
So
''********************
Set Me.Recordset = tbl
''********************
In you code:
Private Sub Form_open(cancel As Integer)
Dim strConnection, strSQL As String
Dim conn As ADODB.Connection
Dim tbl As ADODB.Recordset
Dim SourceCode As String
Dim myID As Variant
Set conn = New ADODB.Connection
strConnection = "ODBC;Driver={SQLserver};DSN=AccessDatabase;Server=Labor;DATABASE=Source;Trusted_Connection=Yes;"
conn.Open strConnection
myID = CInt(Me.OpenArgs)
SourceCode= Nz(DLookup("[SourceCode]", "Locaton", "[LOC_ID] = Forms!frmUtility![Site].value"), "")
If SourceCode<> "" Then
strSQL = "SELECT EmployeeID,BenefitID,DeductionAmount,BenefitAmount,CoverageAmount,EffectiveDate,"
strSQL = strSQL & "EligibleDate,ExpirationDate FROM "
strSQL = strSQL & SourceCode & "_EmployeesBenefitsNew WHERE EmployeeID= " & myID
Else
strSQL = "SELECT EmployeeID,BenefitID,DeductionAmount,BenefitAmount,CoverageAmount,EffectiveDate,"
strSQL = strSQL & "EligibleDate,ExpirationDate FROM "
strSQL = strSQL & "EmployeesBenefitsNew WHERE EmployeeID= " & myID
End If
Set tbl = New ADODB.Recordset
With tbl
Set .ActiveConnection = conn
.Source = strSQL
.LockType = adLockOptimistic
.CursorType = adOpenKeyset
.CursorLocation = adUseClient
.Open
End With
''********************
Set Me.Recordset = tbl
''********************
conn.Close
Set conn = Nothing
Set tbl = Nothing
