MyString = "All men are created equal"
Debug.PrintLen( MyString)
Now that's easy. But how about just counting
the letter "e"? Or, if I were curious to know
how many commas were in the string. How
might one do this in a query?
Suppose a table had single string field with
100 records, each containg a sentence
from a textbook. What would the SQL look
like in a query that listed all 100 sentences
and the number of e's appearing in each
sentence? 4 23613
Replace the character with nothing, and the difference in length is the
count of the character instances.
The query would be something like this:
SELECT Len([MyField]) - Len(Replace([MyField], ",", "")) AS CountOfCommas
FROM Table1;
This should work in Access 2002, 2003, and 2007.
It won't work in A97 or earlier.
In A2000, you may strike this problem: http://support.microsoft.com/kb/225956

Hi -
This will work in A97.
Function StrCount(ByVal TheStr As String, theItem As Variant) As Integer
'------------------------------------------------------------------
' Purpose: Counts the numbers of times an item occurs
' in a string.
' Coded by: raskew
' Arguments: TheStr: The string to be searched.
' TheItem: The item to search for.
' Returns: The number of occurences as an integer.
'
' Note: To test: Type '? StrCount("The quick brown fox jumped over
' the lazy dog", "the") in the debug window.
' The function returns 2.
'------------------------------------------------------------------
Dim i As Integer
Dim j As Integer
Dim placehold As Integer
Dim strHold As String
Dim itemhold As Variant
strHold = TheStr
itemhold = theItem
j = 0
If InStr(1, strHold, itemhold) 0 Then
While InStr(1, strHold, itemhold) 0
placehold = InStr(1, strHold, itemhold)
j = j + 1
strHold = Mid(strHold, placehold + Len(itemhold))
Wend
End If
StrCount = j
End Function

Hi all,
As an exercise, I am trying to come up with a function to count the
length of a char* string using recursion. I came up with this:
int count_length(char* s){
if(s == 0)
return 0;
else{
s++;
return 1 + count_length(s);

I'd like to use the index-function to retrieve a certain char in a
string, but i need it to start counting from the last char.
E.g. in the string.
Foo-bar, foo foo-bar
I want the latter hyphen to be returned when i do a index for '-'. Is
there any built in function for this, I don't want to reverse every
string just to do this.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
