I want display table data in a list box with this code:
Me.List_history.RowSource = "SELECT Date " & _
"FROM Leaves " & _
"WHERE CodePersonali = " & Nz(Me.CodePersonali.Value)
but the list box doesn't display anything
List_history = my list box name
Date = field name in leave table
Date is a reserved word (it's a function), so you shouldn't use it as column name. If you must, put it between square brackets [Date].
If CodePersonali is a text column, you need to put the value between ''.
That would be
Me.List_history.RowSource = "SELECT [Date] " & _
"FROM Leaves " & _
"WHERE CodePersonali = '" & Nz(Me.CodePersonali.Value) & "'"

I'm trying to loop through a column inside a table from a form in Access to find out whether a "Case Name" already exists or not, and if it does not, then add the new record to the table. I want the criteria to be based on the input value of a text box. The good news is I have figured out how to add a new record to the table with the code below. I'm just stuck on how to loop through a table to find out if a record already exists. Thanks in advance!
Private Sub SaveNewCase_Click()
If Me.txtNewCaseName.Value <> "Null" And Me.txtCaseDepth.Value <> "Null" And Me.txtCaseHeight2.Value <> "Null" And Me.txtCaseWeight.Value <> "Null" And Me.txtCaseWidth <> "Null" And Me.cboCaseCategory.Value <> "Null" Then
'I think the loop should go here, but not sure'
CurrentDb.Execute "INSERT INTO tblCases(CaseName, CaseWidth, CaseHeight, CaseCasters, CaseWeight, CaseDepth, CaseCategory) " & _
" VALUES ('" & Me.txtNewCaseName & "'," & Me.txtCaseWidth & "," & Me.txtCaseHeight2 & ",'" & Me.chkboxCasters & "'," & Me.txtCaseWeight & "," & Me.txtCaseDepth & ",'" & Me.cboCaseCategory & "')"
Else
MsgBox "Please enter all new case criteria."
End If
End Sub
Firstly, use parameters!
Concatenating values supplied by a user directly into your SQL statement exposes your to SQL injection, either intentional (i.e. users entering their own SQL statements to sabotage your database) or unintentional (e.g. users entering values containing apostrophes or other SQL delimiters).
Instead, represent each of the field values with a parameter, for example:
With CurrentDb.CreateQueryDef _
( _
"", _
"insert into " & _
"tblcases (casename, casewidth, caseheight, casecasters, caseweight, casedepth, casecategory) " & _
"values (#casename, #casewidth, #caseheight, #casecasters, #caseweight, #casedepth, #casecategory) " _
)
.Parameters("#casename") = txtNewCaseName
.Parameters("#casewidth") = txtCaseWidth
.Parameters("#caseheight") = txtCaseHeight2
.Parameters("#casecasters") = chkboxCasters
.Parameters("#caseweight") = txtCaseWeight
.Parameters("#casedepth") = txtCaseDepth
.Parameters("#casecategory") = cboCaseCategory
.Execute
End With
Since the value of each form control is fed directly to the parameter within the SQL statement, the value will always be interpreted as a literal and cannot form part of the SQL statement itself.
Furthermore, you don't have to worry about surrounding your string values with single or double quotes, and you don't have to worry about formatting date values - the data is used in its native form.
Where testing for an existing value is concerned, you can either use a domain aggregate function, such as DLookup, or you could use a SQL select statement and test that no records are returned, e.g.:
Dim flg As Boolean
With CurrentDb.CreateQueryDef _
( _
"", _
"select * from tblcases where " & _
"casename = #casename and " & _
"casewidth = #casewidth and " & _
"caseheight = #caseheight and " & _
"casecasters = #casecasters and " & _
"caseweight = #caseweight and " & _
"casedepth = #casedepth and " & _
"casecategory = #casecategory " _
)
.Parameters("#casename") = txtNewCaseName
.Parameters("#casewidth") = txtCaseWidth
.Parameters("#caseheight") = txtCaseHeight2
.Parameters("#casecasters") = chkboxCasters
.Parameters("#caseweight") = txtCaseWeight
.Parameters("#casedepth") = txtCaseDepth
.Parameters("#casecategory") = cboCaseCategory
With .OpenRecordset
flg = .EOF
.Close
End With
End With
If flg Then
' Add new record
Else
' Record already exists
End If
Finally, you're currently testing the values of your form controls against the literal string "Null", which will only be validated if the user has entered the value Null into the control, not if the control is blank.
Instead, you should use the VBA IsNull function to check whether a variable holds a Null value.
First this is my first post so I apologize for the layout or any other errors with presentation.
I have two tables.
tempWkEndHrs: Is created when the user selects a weekending date and their name from two comboboxs. The result is 5 fields: Name1, Task, Closed Date, Initiated Date and #xx/xx/xxxx# <--the same date as chosen by the user from the combobox to create the table. This is done to limit the number of date fields returned and built into the temp table.
The purpose of this table is so the user can populate as many values under the #xx/xx/xxxx# field/column to show/see the distribution of hours taken on tasks for that week. (its also used as a check to make sure entered values sum up as expected)
I would like to save the new values entered underfield #xx/xx/xxxx# in tempWkEndHrs to the same field #xx/xx/xxxx# in tblHrs.
tblHrs: has fields... Task , #xx/xx/xxxx#, #xx/xx/xxxx#, #xx/xx/xxxx#, #xx/xx/xxxx#, etc.. <--Same dates available within combobox.
I have having difficulty finding an example of updating multiple records from one table to another to fit my situation.
Below is my last attempt from several variations.
Dim strITEM As String
Dim strWkEnd As String
strWkEnd = Me.cmbWkEnd
strSQL = "UPDATE tblHrs SET " & _
"[" & strWkEnd & "] = [" & strWkEnd & "] " & _
"FROM tempWkEndHrs " & _
" WHERE [Task] = [Task]"
*Update 10-24-2017 5:37pm
Dim strITEM As String
Dim strWkEnd As String
strWkEnd = Me.cmbWkEnd
strSQL = "UPDATE tblHrs " & _
"SET tempWkEndHrs.[" & strWkEnd & "] = tblHrs.[" & strWkEnd & "] "& _
"FROM tempWkEndHrs " & _
" WHERE tempWkEndHrs.[Task] = tblHrs.[Task]"
Result:
UPDATE tblHrs SET tempWkEndHrs.[9/30/2017] = tblHrs.[9/30/2017] FROM tempWkEndHrs WHERE tempWkEndHrs.[TASK] = tblHrs.[TASK]
***Run-Time error '3075
***Syntax error(missing operator) in query expression 'tblHrs.[9/30/2017] FROM tempWkEndHrs'.
If this is clear as mud please let me know.

5.You don't need the FROM tblTemp clause in the SQLReplace String.
6.EDIT: As #Parfait pointed out, tblTemp does not exist in scope of the SQLReplace statement. You should do an INNER JOIN to fix that: <--AWESOME!!
strWkEnd = Me.cmbWkEnd
strSQL = "UPDATE tblHrs INNER JOIN tempWkEndHrs ON tblHrs.TASK = tempWkEndHrs.TASK SET tblHrs.[" & strWkEnd & "] = tempWkEndHrs.[" & strWkEnd & "] "
Works! >:P
I didn't receive any answers to this post so obviously I need to write better questions, I figured it was mud...Thanks for the ~21 Views ?lol.
I am creating form in access in which i have to implement cascading combo boxes , data in lower combo box is dependent on its parent value selected by user. Here is form
on left side is structure of the table and on right side is form. Problem is I am getting error of data type mismatch , unable to understand why this is happening. In the afterupdate event of Diametre of Drill I am populating cutting speed . Whenever I press drop down of Cutting Speed "Datatype mismatch in criteria expression" occurs. Here is code of afterupdate event of Diametre of Drill
Private Sub cboDiameterDrilling_AfterUpdate()
cboCuttingSpeedDrilling.RowSource = "Select DISTINCT tblDrilling.cuttingSpeed " & _
"FROM tblDrilling " & _
`"WHERE tblDrilling.materials = '" & cboMaterialDrilling.Value & "' AND tblDrilling.diaOfDrill = '` `cboDiameterDrilling.Value ' " & _`
"ORDER BY tblDrilling.cuttingSpeed;"
End Sub
I think problem is in WHERE Clause . Any help would be greatly appreciated. Thank you
You've surrounded the reference to the object's value (cboDiameterDrilling.Value ) in single quotes.
AND tblDrilling.diaOfDrill = ' & cboDiameterDrilling.Value & "'"
Solution : AND tblDrilling.diaOfDrill = " & cboDiameterDrilling.Value & " " & _
I think you missed a ". Try:
Private Sub cboDiameterDrilling_AfterUpdate()
cboCuttingSpeedDrilling.RowSource = "Select DISTINCT tblDrilling.cuttingSpeed " & _
"FROM tblDrilling " & _
`"WHERE tblDrilling.materials = '" & cboMaterialDrilling.Value & "' AND tblDrilling.diaOfDrill = '" & cboDiameterDrilling.Value & "' " & _
"ORDER BY tblDrilling.cuttingSpeed;"
End Sub
Summary:
I want to display a value (in a text box) stored in another form upon choosing specific values from combo boxes.
I want to pass the two combo box values I have into the DLoopup property but every time I do so it gives me an error.
Below is the code is inserted in the control source property of a text box:
=DLookUp("[Year_ended]","1_Supportive_Housing","[BudgetYear] ='" & [Combo5] & "'")
This gives me an "#Error" in the text box.
Also tried the following but gives me "#NAME" error:
=DLookUp("[Year_ended]","1_Supportive_Housing","[BudgetYear] = '" & [Combo5.Value] & " And [Program_Name] = '" & [Combo7.Value] & "'")
You need to get your delimiters sorted out. AFAIR Budget Year is a number:
=DLookUp("[Year_ended]","1_Supportive_Housing","[BudgetYear] =" & [Combo5])
When you are passing a value to a numeric type field, you do not use delimiters, for text, you use quotes, either 'Abc' or "Abc", for dates, use hash (#) #2012/11/31#.
=DLookUp("[Year_ended]","1_Supportive_Housing","[BudgetYear] =" & [Combo5] & " And [Program_Name] = '" & [Combo7.Value] & "'")
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.
