I have a ms access database and when I try to update a column in a module I get the error "Mismatch datatype criteria expression", when I create the column the datatype was TEXT(25) and the value that I'm trying to assign is a String:
Dim str As String
str = "test"
sql = "UPDATE Table "
sql = sql & "SET Table.[column] ='" & str & "' "
sql = sql & "WHERE Table.[id] = 1;"
MsgBox(sql)
Application.CurrentDb.Execute(sql)
In the MsgBox the string of query appears to be right: "UPDATE Table SET Table.[Column]='test' WHERE Table.[id]=1;
Which is the error?, how to fix this?
If Table.id is a numeric column your where clause is okay, but if it is a text column it should read:
WHERE Table.id = '1'

Dim db As Database
Dim rrs As Recordset
Dim strselect As String
Set db = CurrentDb
strselect = "SELECT [Stok Pembelian] FROM t_databarang WHERE [ID Barang]= '" & Me.Text7 & "'"
Set rrs = db.OpenRecordset(strselect)
Me.Label1.Caption = rrs![Stok Pembelian]
I have a project from my school. I'm beginers and i'm so confused about my Access. I think that code it's correct, but there's an error "Data type mismatch in criteria expression." I already search much articles about how tow to fix it but not found. Please, help me.
Your id is most likely a number, thus no quotes:
strselect = "SELECT [Stok Pembelian] FROM t_databarang WHERE [ID Barang]= " & Me!Text7.Value & ""
Try to convert the textbox value into a double or int...
Dim Text7a as Double
Text7a = CLng(Me.Text7) 'Beware of rounding with Long Integers
Now use the alias Text7a for:
strselect = "SELECT [Stok Pembelian] FROM t_databarang WHERE [ID Barang]= '" & Me.Text7a & "'"
Check data types!
Like "Long Text do not match Number data type." Do it both them same data type on your database design
I have a update like this in a module of ms access:
sql = "ALTER TABLE Carrera "
sql = sql & "ADD COLUMN carrera_nombre TEXT(25);"
Application.CurrentDb.Execute (sql)
sql = "UPDATE Carrera "
sql = sql & "SET Carrera.[carrera_nombre] = '" & strFunction(Carrera.[NombreCarrera]) & "' "
sql = sql & "WHERE Carrera.[CarreraId] > 1000;"
Application.CurrentDb.Execute (sql)
In database the column NombreCarrera exist, and I declared the function:
Function strFunction(str) As String
strFunction = str & "test"
End Function
But I get the error 3464 Not match the datatypes of the criteria expression, and I don't understand why, the strFunction return a String and the carrera_nombre and CarreraNombre columns type is TEXT.
EDIT: If I check string sql through MsgBox(sql) y get the right query: UPDATE Carrera SET Carrera.[carrera_nombre] = 'mathtest' WHERE Carrera.[CarreraId] > 1000;
I believe since you declare the sql command as a string, you will have to get it first.
so one of your code
sql = sql & "SET Carrera.[carrera_nombre] = strFunction(Carrera.[NombreCarrera])"
Should become
sql = sql & "SET Carrera.[carrera_nombre] = " & strFunction(Carrera.[NombreCarrera]) & """
Was wondering how can we put an SQL statement in a String Variable?
Example:
Dim sqlQuery as String, qHolder as String
sqlQuery = "SELECT ID.table from table WHERE ID ='" userInputTextBox "'"
Whenever i do the above statement using either OpernRecordset() or RecordSource it gives me a bug. Can you give an example on how we do this, so we can use the value of sqlQuery for comparison for example
if(sqlQuery = userInputTextBox)then
MSgBox(" Match Found " )
Else
MsgBox("No Match Found")
Big Thanks in Advance.
Use the string concatenation operator (&).
sqlQuery = "SELECT ID.table from table WHERE ID ='" & userInputTextBox & "'"
Otherwise, it's a syntax error.
UPDATE
To get the value of ID.table into a string, use the Fields property of the Recordset:
Dim s As String
' by index
s = MyRec.Fields(0)
' or by name
s = MyRec.Fields("ID.table")
I am trying to build SELECT statement in Access VBA, based on value chosen by user in ComboBox.
Example :
"SELECT [8_SV_RT] FROM DATA WHERE condition = value
I need 8 to be dependent on ComboBox value from form. (8,10,12 ....)
The name of ComboBox is DN, and I created string COL = "_SV_RT"
So far I have :
"SELECT [DN] & '" & COL & "' FROM DATA WHERE condition = value
It returns value 8_SV_RT to ComboBox, which I want to use after SELECT statement, but not as result. I must be missing some syntax or something? Can anyone please advise?
If I understand your question right:
Dim SQL As String
SQL = "SELECT [" & Me.MyComboBox & "_SV_RT] FROM DATA WHERE condition = value"
EDIT:
To use the exact object names from the question (before Siddharth edited it, I over-read that the combobox is named DN) and to take Siddharth's (now deleted) comment into consideration:
Dim SQL As String
Dim COL As String
COL = "_SV_RT"
SQL = "SELECT [" & DN & COL & "] FROM DATA WHERE condition = value"
I have a listbox select and I want when the user selects null for the empty string it produces to pull the nulls from the SQL table.
Here's what I have now. Blank strings return nothing because there are no empty fields in the table.
SELECT * FROM dbo.Table WHERE ID = " & TextBox2.Text & " and And Field1 IN (" & Msg1 & ")
How do I code that?
Use an If statement. When your textbox is empty, have the SQL string contain "ID is null" instead of appending the textbox's value.
If (TextBox1.Text = "") Then
' use Is Null in your sql statement
Else
' use the textbox text value in your sql statement
End If
(Assuming you're talking about the textbox and not whatever Msg1 is.)
dim sql
If (TextBox2.Text = null) Then
sql = "SELECT * FROM dbo.Table WHERE ID is null and And Field1 IN (" & Msg1 & ")"
Else
sql = "SELECT * FROM dbo.Table WHERE ID = " & TextBox2.Text & " and And Field1 IN (" & Msg1 & ")"
End If
See #John Saunders comment, you are risking sql injections. When passing paremeter to an sql query, be sure to use parameters, and not concatenating strings.
SELECT * FROM dbo.Table WHERE ID = " & TextBox2.Text &
" And Field1 " & IIF(Trim(Msg1) = "", "IS NULL", "IN (" & Msg1 & ")")
Yes, it is crude.
One should not write query in this style.
EDIT: Corrected. Please check.
