Hi Guys,
I was wondering if soemone could help me.
Im trying to write a piece of code that queries a field in ms access
for a keyword. what i want to do is count the number of times the
keyword exists in the memo field and store that in a temporary table.
My problem is the query to count the number of times the keyword is in
the field.
can anyone please help me ??
thanks

You could use nested instr functions. Just start the next instr after
the substr where it found the last one. You just won't be able to
search for more then 5 or 6 words because the query will be too
complex to run.
e.g.
str = "String to be searched for a string"
iif(instr(0, str, "string")>0 , iif(instr(0, instr(0, str, "string") -
(len(str)+len(" string"), "string")>0 , 2,1),0)
Otherwise you will need to make a VBA function to loop through the
words in the string to find what your looking for.

NumberOfTimes:( Len([FieldName])-Len(Replace([FieldName],"bus","")))/3
Let's say you wish to count the number of times the word "bus" appears
in a field.
THE BUS IS A VERY BUSY BUSINESS. The query would return back a "3".
The /3 part is whatever the number of characters in the search string
(i.e. "bus") is.

greatest number of instances of a certain set of keywords.

I have a crystal report that someone else wrote and already has a Formula Field
if Criteria then (Count ({FirstField},{SecondField}) / Count ({FirstField}))
When the Criteria is true, this calculates a percentage for all rows. This Formula Field is then used as data in a bar chart that uses FirstField for the x-axis and the percentage for the y-axis. That was all already working just fine.
Now I need to change it so that the Count...

I am wanting to create a report that summarises the number of items within a date range.
For example I have a FIELD called System_Change.
This is a drop down COMBOBOX that uses words like unix, polfs etc.
I know how to query a date range, but not how to count number of fields within this date range.
I would like the report to show date range filtered then list all changes and number of times they appear.
Thanks in advance anything...

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.
