Microsoft Access VBA code with Select SQL String and Where clause - vba

I'm using Microsoft Access to develop a database app. An important feature the user would need is to automatically send an email update to all relevant stakeholders.
The problem is that I'm getting
Run-time error '3075' Syntax error in query expression.
Here it is below:
Set rs = db.OpenRecordset("SELECT StakeholderRegister.[StakeholderID], StakeholderRegister.[ProjectID], StakeholderRegister.[FirstName], StakeholderRegister.[LastName], StakeholderRegister.[EmailAddress] " & _
" FROM StakeholderRegister " & _
" WHERE (((StakeholderRegister.[ProjectID]=[Forms]![ChangeLog]![cboProjectID.Value])) ;")
Funny thing is that I created a query table on Access to create the relevant recordset and the turned on SQL view to copy the exact sql string that's above. That query works however it opens an Input Parameter box, whereas this code should be using the value typed into a forms text box as a matching criteria.

To use a variable as a parameter, do not include it within the quotes:
" WHERE StakeholderRegister.[ProjectID]=" & [Forms]![ChangeLog]![cboProjectID].[Value]
or just
" WHERE StakeholderRegister.ProjectID=" & Forms!ChangeLog!cboProjectID.Value
Note: You really only need the square brackets when there is something like a space in the name, which is not the best practice anyway.
I also took the liberty to remove the parentheses, as they are not needed in such a simple WHERE clause, and can cause more trouble than they are worth.

Try,
Dim strSQL As String
strSQL = "SELECT StakeholderRegister.[StakeholderID], StakeholderRegister.[ProjectID], StakeholderRegister.[FirstName], StakeholderRegister.[LastName], StakeholderRegister.[EmailAddress] " & _
" FROM StakeholderRegister " & _
" WHERE StakeholderRegister.[ProjectID]=" & [Forms]![ChangeLog]![cboProjectID].Value & " ;"
Set rs = Db.OpenRecordset(strSQL)
if [ProjectID] field type is text then
Dim strSQL As String
strSQL = "SELECT StakeholderRegister.[StakeholderID], StakeholderRegister.[ProjectID], StakeholderRegister.[FirstName], StakeholderRegister.[LastName], StakeholderRegister.[EmailAddress] " & _
" FROM StakeholderRegister " & _
" WHERE StakeholderRegister.[ProjectID]='" & [Forms]![ChangeLog]![cboProjectID].Value & "' ;"
Set rs = Db.OpenRecordset(strSQL)

Run Time error 3061 Too Few parameters. Expected 6. Unable to update table from listbox

All,
I am running the below SQL and I keep getting error 3061. Thank you all for the wonderful help! I've been trying to teach myself and I am 10 days in and oh my I am in for a treat!
Private Sub b_Update_Click()
Dim db As DAO.Database
Set db = CurrentDb
strSQL = "UPDATE Main" _
& " SET t_Name = Me.txt_Name, t_Date = Me.txt_Date, t_ContactID = Me.txt_Contact, t_Score = Me.txt_Score, t_Comments = Me.txt_Comments" _
& " WHERE RecordID = Me.lbl_RecordID.Caption"
CurrentDb.Execute strSQL
I am not sure but, you can try somethink like that
if you knom the new value to insert in the database try with a syntax like this one
UPDATE table
SET Users.name = 'NewName',
Users.address = 'MyNewAdresse'
WHERE Users.id_User = 10;
Now, if you want to use a form (php)
You have to use this
if(isset($_REQUEST["id_user" ])) {$id_user = $_REQUEST["id_user" ];}
else {$id_user = "" ;}
if(isset($_REQUEST["name" ])) {$name= $_REQUEST["name" ];}
else {$name = "" ;}
if(isset($_REQUEST["address" ])) {$address= $_REQUEST["adress" ];}
else {$adress= "" ;}
if you use mysql
UPDATE table
SET Users.name = '$name',
Users.address = '$adress'
WHERE Users.id_User = 10;
i don't know VBA but I will try to help you
Going on from my comment, you first need to declare strSQL as a string variable.
Where your error expects 6 values and access doesn't know what they are. This is because form objects need to be outside the quotations of the SQL query, otherwise (as in this case) it will think they are variables and obviously undefined. The 6 expected are the 5 form fields plus 'strSQL'.
Private Sub b_Update_Click()
Dim db As DAO.Database
dim strSQL as string
Set db = CurrentDb
strSQL = "UPDATE Main" & _
" SET t_Name = '" & Me.txt_Name & "'," & _
" t_Date =#" & Me.txt_Date & "#," & _
" t_ContactID =" & Me.txt_Contact & "," & _
" t_Score =" & Me.txt_Score & "," & _
" t_Comments = '" & Me.txt_Comments & "'," & _
" WHERE RecordID = '" & Me.lbl_RecordID.Caption & "';"
CurrentDb.Execute strSQL
end sub
Note how I have used double quotes to put the form fields outside of the query string so access knows they aren't variables.
If your field is a string, it needs encapsulating in single quotes like so 'string'. If you have a date field it needs encapsulating in number signs like so #date# and numbers/integers don't need encapsulating.
Look at the code I have done and you can see I have used these single quotes and number signs to encapsulate certain fields. I guessed based on the names of the fields like ID's as numbers. I may have got some wrong so alter where applicable... Or comment and I will correct my answer.

VBA Assign a RecordSet Field to a ComboBox

I have the following code:
sSQL = "SELECT CODER FROM " & dbfname & " IN " & dir & " WHERE TRIM(CODEK) = TRIM(kCode)"
Combo29.RowSource = sSQL
Combo29.Requery
, where "CODER" is a field in the dbf file. "CODEK" is also a field in that dbf file, which im comparing with the string kCode.
When I run the code and when I click on the combobox, it asks me to enter arguments instead of showing the selected arguments. The RowSource type is set to Table/Query.
Is the assigning statement incorrect and how can I modify it to show me list of results from the SQL statement?
If I understand your problem correctly kCode is a string in VBA so you'll have to set up your SQL string the following way
sSQL = "SELECT CODER FROM " & dbfname & " IN " & dir & " WHERE TRIM(CODEK) = TRIM('" & kCode & "')"`

ACCESS/SQL - Too Few Parameters

I am using the code below to create a new record in the "transactions table" the second line of the insert statement is throwing an error: Too few parameters. I have double checked and all of the field names are correct. What else could cause this type of error?
' Modify this line to include the path to Northwind
' on your computer.
Set dbs = CurrentDb
Dim vblCustomerID As String
Dim vblMealType As String
Dim Charge As Currency
Dim vblDate As String
vblDate = Format(Date, "yyyy-mm-dd")
txtCustomerID.SetFocus
vblCustomerID = txtCustomerID.Text
txtMealType.SetFocus
vblMealType = txtMealType.Text
txtCharge.SetFocus
vblCharge = txtCharge.Text
dbs.Execute "INSERT INTO dbo_Transactions" _
& "(CustomerID, MealID, TransactionAmount, TransactionDate) VALUES " _
& "(" & vblCustomerID & ", " & vblMealType & ", " & vblCharge & ", " & vblDate & ");"
dbs.Close
As others have suggested, using a parameterized query is a much better way of doing what you're attempting to do. Try something like this:
Dim qdf As DAO.QueryDef
Set qdf = dbs.CreateQueryDef("", _
"PARAMETERS prmCustomerID Long, prmMealID Long, prmTransactionAmount Currency, prmTransactionDate DateTime;" & _
"INSERT INTO dbo_Transactions (CustomerID, MealID, TransactionAmount, TransactionDate) " & _
"VALUES ([prmCustomerID], [prmMealID], [prmTransactionAmount], [prmTransactionDate]) ")
qdf!prmCustomerID = txtCustomerID.Value
qdf!prmMealID = txtMealType.Value
qdf!prmTransactionAmount = txtCharge.Value
qdf!prmTransactionDate = Date()
qdf.Execute dbFailOnError
Set qdf = nothing
Do any of the text fields you're loading into your vbl fields contain special characters like these?
, ' "
All of those in a text field in a perfectly good SQL Insert command could screw things up, I bet that's what happening here.
It would be better if you actually use parameters here to, rather than loading the text in textboxes directly into your SQL queries, since you're opening yourself up to SQL Injections. What if someone types
"; Drop Table dbo_Transactions;
in one of your textboxes and you run this query? Your database is then totally screwed up because someone just deleted one of your tables.
A few links to info on using Parameters to prevent this issue, which I'll bet will also fix the too few parameters issue you're having.

Inserting into a different table from a form

I am trying to make an event when iputing data in a form on access, after the text box looses focus, if the box is not null I want the ID and the value to get stored into another table. After trying with the code below I get "Runtime error 3061 Too few parameters Expected 1". I have checked in debug mode and the values are getting carried over and brought to the string.
Private Sub Consolidate_LostFocus()
Dim queryString As String
queryString = "INSERT INTO [ReportMasterTable]([#], [Notes]) VALUES(" & [#].Value & ", " & [Consolidate].Value & ")"
If Consolidate.Text <> vbNullString Then
CurrentDb.Execute (queryString)
End If
End Sub
If either the # or the Notes fields in ReportMasterTable is text data type, you must add quotes around the values you attempt to INSERT.
For example, if both fields are text type:
queryString = "INSERT INTO [ReportMasterTable]([#], [Notes])" & vbCrLf & _
"VALUES ('" & [#].Value & "', '" & [Consolidate].Value & "')"
The situation will be more complicated if either [#].Value or [Consolidate].Value contains a single quote. You could double up the single quotes within the inserted values. However it might be easier to just switch to a parameterized query ... the quoting problem would go away.
Dim db As DAO.database
Dim qdf As DAO.QueryDef
Dim strInsert As String
strInsert = "PARAMETERS hash_sign Text (255), note_value Text (255);" & vbCrLf & _
"INSERT INTO [ReportMasterTable]([#], [Notes])" & vbCrLf & _
"VALUES (hash_sign, note_value)"
Set db = CurrentDb
Set qdf = db.CreateQueryDef("", strInsert)
qdf.Parameters("hash_sign").value = Me.[#]
qdf.Parameters("note_value").value = Me.[consolidate]
qdf.Execute dbFailOnError
Set qdf = Nothing
Set db = Nothing
You could also save the SQL statement as a named query and open and execute that instead of rebuilding the statement every time your procedure runs.
Is there any reason why you do not wish ti bind the form to the ReportMasterTable?
If you really have a control and field called #, you are facing a world of trouble.
If you have bound the form to ReportMasterTable and are also updating in a query, you are going to run into problems.
The lost focus event is a very bad event to choose, any time anyone tabs through the form, the code will run. After update would be better.
You are updating a text data type, but you have not used quotes.
"INSERT INTO [ReportMasterTable]([#], [Notes]) VALUES(" & [#].Value _
& ", '" & [Consolidate].Value & "')"

VBA string length problem

I have an Access application where everytime a user enters the application, it makes a temp table for that user called 'their windows login name'_Temp. In one of my reports I need to query using that table, and I can't just make a query and set it as the recourdsource of the report, since the name of the table is always different.
What I tried then was to programatically set the recordset of the report by running the query and setting the form's recordset as the query's recordset. When I tried this, it kept giving me an error about the query.
I tried to debug, and I found that the string variable isn't able to contain the whole query at once. When I ran it with break points and added a watch for the string variable, it shows me that it cuts off the query somewhere in the middle.
I've experienced this problem before, but that was with an UPDATE query. Then, I just split it into two queries and ran both of them separately. This one is a SELECT query, and there's no way I can split it. Please help!
Thank you
Heres what I've tried doing:
ReturnUserName is a function in a module that returns just the login id of the user
Private Sub Report_Open(Cancel As Integer)
Dim strQuery As String
Dim user As String
user = ReturnUserName
strQuery = "SELECT " & user & "_Temp.EmpNumber, [FName] & ' ' & [LName] AS [Employee Name], " & _
"CourseName, DateCompleted, tblEmp_SuperAdmin.[Cost Centre] " & _
"FROM (tblCourse INNER JOIN (" & user & "_Temp INNER JOIN tblEmpCourses ON " & _
user & "_Temp.EmpNumber = EmpNo) ON tblCourse.CourseID = tblEmpCourses.CourseID) " & _
"INNER JOIN tblEmp_SuperAdmin ON " & user & "_Temp.EmpNumber = tblEmp_SuperAdmin.EmpNumber" & _
"WHERE (((" & user & "_Temp.EmpNumber) = [Forms]![Reports]![txtEmpID].[Text])) " & _
"ORDER BY CourseName;"
Dim rs As ADODB.Recordset
Set rs = New ADODB.Recordset
Dim rsCmd As ADODB.Command
Set rsCmd = New ADODB.Command
rsCmd.ActiveConnection = CurrentProject.Connection
rsCmd.CommandText = strQuery
rs.Open rsCmd
Me.Recordset = rs
rs.Close
End Sub
This what strQuery contains when I add a breakpoint on rsCmd.CommandText = strQuery:
SELECT myusername_Temp.EmpNumber, [FName]
& ' ' & [LName] AS [Employee Name],
CourseName, DateCompleted,
tblEmp_SuperAdmin.[Cost Centre] FROM
(tblCourse INNER JOIN (myusername_Temp
INNER JOIN tblEmpCourses ON
myusername_Temp.EmpNumber = EmpNo) ON
tblCourse.CourseID=
(It's all one line, but I've written it like this because the underscores italicize the text)
And the error I get says Run Time Error: Join not Supported.
Not quite what I was hoping for, but guessing, for:
strQuery = "long query goes here"
Try:
strQuery = "some long query goes here "
strQuery = strQuery & "more query goes here "
BASED ON NEW INFORMATION:
strQuery = "SELECT " & user & "_Temp.EmpNumber, [FName] & ' ' & [LName] AS [Employee Name], " & _
"CourseName, DateCompleted, tblEmp_SuperAdmin.[Cost Centre] " & _
"FROM (tblCourse " & _
"INNER JOIN tblEmpCourses ON tblCourse.CourseID = tblEmpCourses.CourseID) " & _
"INNER JOIN (Temp INNER JOIN tblEmp_SuperAdmin " & _
"ON Temp.EmpNumber = tblEmp_SuperAdmin.EmpNumber) " & _
"ON Temp.EmpNumber = tblEmpCourses.EmpNo " & _
"WHERE " & user & "_Temp.EmpNumber = " & [Forms]![Reports]![txtEmpID] & _
" ORDER BY CourseName;"
Note that in VBA:
& [Forms]![Reports]![txtEmpID].[Text] &
That is, the reference to the form must go outside the quotes so you get the value.
NEW INFORMATION #2
Your best bet would be to add these tables to the Access query design window and create the joins that you want, then switch to SQL view and use the string generated for you. I do not believe that the string is too long, only that the SQL is incorrect. The SQL I posted above should work, but it may not be what you want.
You can programmatically create a querydef that fits the user. So, when your report is called, you
Delete LoginName_Query_Temp (CurrentDb.QueryDefs.Delete), if it already exists.
Create the querydef (CurrentDB.CreateQueryDef), using LoginName_Temp as the table name.
Set the RecordSource of your Report to LoginName_Query_Temp.
Open the report.
I don't see what purpose the table myusername_Temp serves here. Is that where the name fields are? If so, avoid the join entirely:
Dim lngEmpNumber As Long
Dim strName As String
Dim strSQL As String
lngEmpNumber = Forms!Reports!txtEmpID
strName = DLookup("[FName] & ' ' & [LName]", "myusername_Temp", "EmpNumber=" & lngEmpNumber
strSQL = "SELECT " & Chr(34) & strName & Chr(34) & " AS [Employee Name], " & _
"CourseName, DateCompleted, tblEmp_SuperAdmin.[Cost Centre] " & _
"FROM tblCourse " & _
"INNER JOIN tblEmpCourses " & _
"ON tblCourse.CourseID = tblEmpCourses.CourseID) " & _
"INNER JOIN tblEmp_SuperAdmin " & _
"ON tblEmp_SuperAdmin.EmpNumber = tblEmpCourses.EmpNo " & _
"WHERE tblEmp_SuperAdmin.EmpNumber = " & lngEmpNumber & _
" ORDER BY CourseName;"
Now, the parentheses may need to be changed in the join (I always do my equi-joins in the Access QBE and let it take care of the getting the order and parens correct!), and my assumptions about the purpose of the temp table may be wrong, but I don't see it being used for anything other than as an intermediate link between tables, so I guessed it must be there to provide the name fields.
If that's wrong, then I'm at a loss as to why the temp table needs to be there.
Also, in your second post you referred to the control on the form as:
Forms!Reports!txtEmpID.Text
...the .Text property of Access controls is accessible only when the control has the focus. You could use the .Value property, but since that's the default property of Access controls, you should just stop after the name of the control:
Forms!Reports!txtEmpID
...you'll see this is how I did it in my suggested code.
I find the idea of your name-based temp table to be highly problematic to begin with. Temp tables don't belong in a front end, and it's not clear to me that it is actually a temp table. If it's temp data, put it in a shared table and key the record(s) to the username. Then you don't have to worry about constructing the table name on the fly.
