I've started to use access recently. I am trying to insert a few rows into the database; however, I am stuck as it is throwing an error:
Too few parameters.
I have a table test with only one column in it named start_date I want to insert all the dates between two dates for example if I consider 1/7/2014 to 3/7/2014 I need dates as 1/7/2014,2/7/2014,3/7/2014 in my table, but I have problem inserting the code I used is as follows
Private Sub createRec_Click()
Dim StrSQL As String
Dim InDate As Date
Dim DatDiff As Integer
Dim db As database
InDate=Me.FromDateTxt
'here I have used a code to find out the difference between two dates that i've not written
For i = 1 To DatDiff
StrSQL = "INSERT INTO Test (Start_Date) VALUES ('" & InDate & "' );"
StrSQL = StrSQL & "SELECT 'Test'"
db.Execute StrSQL
db.close
i=i+1
next i
End Sub
My code throws an error in the line Db.Execuite StrSQL as too few parameters. Hope somebody could help me with this issue. Thanks In advance

since you mentioned you are quite new to access, i had to invite you to first remove the errors in the code (the incomplete for loop and the SQL statement). Otherwise, you surely need the for loop to insert dates in a certain range.
Now, please use the code below to insert the date values into your table. I have tested the code and it works. You can try it too. After that, add your for loop to suit your scenario
Dim StrSQL As String
Dim InDate As Date
Dim DatDiff As Integer
InDate = Me.FromDateTxt
StrSQL = "INSERT INTO Test (Start_Date) VALUES ('" & InDate & "' );"
DoCmd.SetWarnings False
DoCmd.RunSQL StrSQL
DoCmd.SetWarnings True
You can't run two SQL statements into one like you are doing.
You can't "execute" a select query.
db is an object and you haven't set it to anything: (e.g. set db = currentdb)
In VBA integer types can hold up to max of 32767 - I would be tempted to use Long.
You might want to be a bit more specific about the date you are inserting:
INSERT INTO Test (Start_Date) VALUES ('#" & format(InDate, "mm/dd/yyyy") & "#' );"
in summary: remove those two lines of code above and your insert statement will work fine. You can the modify the code it later to suit your specific needs. And by the way, some times, you have to enclose dates in pounds signs like #
