Calculated Mean

Charles Deng · Oct 10, 2004

Hi All:

I have a query like:

Dept Sec G1 G2 G3 M1 M2 M3
ACC 100 3.5 2.8 3.2
ACC 100 2.6 3.1 3.8
ACC 200 3.5 2.8 3.2
ACC 300 2.6 3.1 3.8
BUS 100 2.6 3.1 3.8
BUS 100 3.5 2.8 3.2
BUS 200 2.6 3.1 3.8
BUS 200 3.5 2.8 3.2

I need to add three calculated fields to this query M1,
M2, and M3. M1 is mean of G1, M2 is mean of G2, and M3 is
mean of G3. All these means are grouped by Dept. What I
did is:

put M1:=avg([G1]) in Field and Group by: [Dept] in Total.
But the access does not accept. What is wrong with what I
did? or what are correct expression I need to type in?
Thanks a lot.

I need to create a new field in the query.

Hi Ken:

Thanks for your interest in this:

SELECT Table1.Dept, Table1.G1, Table1.G2, Table1.G3, Avg
(Table1.G1) AS Expr1
FROM Table1
GROUP BY Table1.Dept, Table1.G1, Table1.G2, Table1.G3
ORDER BY Table1.Dept;

ahhhh....

Try this (uses a subquery):

SELECT Table1.Dept, Table1.G1, Table1.G2, Table1.G3,
(SELECT Avg(T.G1) FROM Table1 AS T
WHERE T.Dept = Table1.Dept) AS M1,
(SELECT Avg(U.G2) FROM Table1 AS U
WHERE U.Dept = Table1.Dept) AS M2,
(SELECT Avg(V.G3) FROM Table1 AS V
WHERE V.Dept = Table1.Dept) AS M3,
FROM Table1
GROUP BY Table1.Dept;

Hi Ken:

Thank you so much for this subquery. But it still does not work yet. I
copied this statement to the Field row, I got a error message:

Check the subquery's syntax and enclose the subquery in parentheses.

When I put a pair of parentheses, the following error message prompted again:

You may have entered an operand without an operator.

I checked this statement again and again but I am not able to find an error.
But when I copied this statement to SQL View (I know I am supposed to do
so), I got the following error message:

The SELECT statement includes a reserved word or an argument name that is
misspelled or missing, or the punctuation is incorrect.

But I still have not any clue where the problem is. Could you check the
statement again to see where the problem is? Thank you very much.

When I put a pair of parentheses to the statement, another error message

There is no way I can fix this problem and I tried to see what would happen

No, don't copy to field row. Create a new query, don't select any tables,
close the table window, click on view icon at top left of toolbar and select
SQL, and paste the SQL statement that I posted into the displayed window
(replace any text already there). Then try the query.

Either something is going wrong when you paste the SQL statement into your
query's window, or something about your setup is different from what I'm
understanding.

Post here the exact statement that your query says has an error in the SQL
(don't post back what I posted, but rather what is in your query's window
when the error occurs).

Hi Ken:

I am terribly sorry for this chronicle hassile. I tried it again this
morning and got the following error messages:

When I copied the statement to the Field (either put M1: or not prior to the
statement), the query window prompted an error message:

The syntax of the subquery in this expression is incorrect.
Check the subquery's syntax and enclose the subquery in parentheses.

When I put a pair of parentheses ( ), immediately before the first word
SELECT and immediately after the last word Table1 (semi column ; disappeared
automatically), the query window prompted:

The expression you entered contains invalid syntax.
You may have entered an operand without an operator.

I know there may be other problem than the statement but I checked the
Table1, variable Dept is text and G1, G2, G3 are all number. It seems
everything is fine. But why the statement does not work. I sincerely
appreciate your time in helping me with this. Thank you very much.

close the table window, click on view icon at top left of toolbar and

Hi Ken:

Thank you so much for this subquery. But it still does not work yet. I
copied this statement to the Field row, I got a error message:

Check the subquery's syntax and enclose the subquery in parentheses.

When I put a pair of parentheses, the following error message prompted
again:

You may have entered an operand without an operator.

I checked this statement again and again but I am not able to find an
error.
But when I copied this statement to SQL View (I know I am supposed to
do
so), I got the following error message:

The SELECT statement includes a reserved word or an argument name that

misspelled or missing, or the punctuation is incorrect.

But I still have not any clue where the problem is. Could you check the

As I have asked a number of times, you need to copy what you have in the SQL
window and paste it back here in a message. I cannot see what you're
actually putting into the SQL window, and thus can't see if there is
something going wrong with the copying process.

After you get the error, copy what is in the SQL window and paste it intoa

Hi All:

I have a query like:

Dept Sec G1 G2 G3 M1 M2 M3
ACC 100 3.5 2.8 3.2
ACC 100 2.6 3.1 3.8
ACC 200 3.5 2.8 3.2

BUS 100 3.5 2.8 3.2
BUS 200 2.6 3.1 3.8
BUS 200 3.5 2.8 3.2

I need to add three calculated fields to this query M1,
M2, and M3. M1 is mean of G1, M2 is mean of G2, and M3
is
mean of G3. All these means are grouped by Dept. What
I
did is:

put M1:=avg([G1]) in Field and Group by: [Dept] in
Total.
But the access does not accept. What is wrong with
what I
did? or what are correct expression I need to type in?
Thanks a lot.

Hi Ken:

Sorry for having delayed to get back to you. I have been busy with another

I copied your statement to SQL screen again but got the same error message.
The statement on the screen:
SELECT Table1.Dept, Table1.G1, Table1.G2, Table1.G3,
(SELECT Avg(T.G1) FROM Table1 AS T
WHERE T.Dept = Table1.Dept) AS M1,

ORDER BY Table1.Dept;

The error message:

The SELECT statement includes a reserved word or an argument name that is
misspelled or missing, or the punctuation isincorrect.

Sorry again to have bothered you some many times. I really appreciate your
help. Thanks a lot again.

As I have asked a number of times, you need to copy what you have in the SQL
window and paste it back here in a message. I cannot see what you're
actually putting into the SQL window, and thus can't see if there is
something going wrong with the copying process.

After you get the error, copy what is in the SQL window and paste it intoa

Hi Ken:

I am terribly sorry for this chronicle hassile. I tried it again this
morning and got the following error messages:

When I copied the statement to the Field (either put M1: or not prior to
the
statement), the query window prompted an error message:

The syntax of the subquery in this expression is incorrect.
Check the subquery's syntax and enclose the subquery in parentheses.

When I put a pair of parentheses ( ), immediately before the first word
SELECT and immediately after the last word Table1 (semi column ;
disappeared
automatically), the query window prompted:

The expression you entered contains invalid syntax.
You may have entered an operand without an operator.

I know there may be other problem than the statement but I checked the
Table1, variable Dept is text and G1, G2, G3 are all number. It seems
everything is fine. But why the statement does not work. I sincerely
appreciate your time in helping me with this. Thank you very much.

I need to add three calculated fields to this query
M1,
M2, and M3. M1 is mean of G1, M2 is mean of G2, and
M3
is
mean of G3. All these means are grouped by Dept.
What
I
did is:

put M1:=avg([G1]) in Field and Group by: [Dept] in
Total.
But the access does not accept. What is wrong with
what I
did? or what are correct expression I need to type
in?
Thanks a lot.

You could create a separate query:

SELECT T.Dept, Avg(T.G1) AS M1,
Avg(T.G2) AS M2, Avg(T.G3) AS M3
FROM Table1 AS T
GROUP BY T.Dept;

Name the above query qryAverages.

Then use this query in place of the one that is slow:

SELECT Table1.Dept, Table1.G1, Table1.G2,
Table1.G3, T.M1, T.M2, T.M3
FROM Table1 INNER JOIN qryAverages AS T
ON Table1.Dept = T.Dept
ORDER BY Table1.Dept;

Hi Ken:

When I used this expression to the real data base (about 5,300 records), it
took so long time to open the query. Is there any way we can have this code
run faster? Thanks.

I think I see the problem...it's an inadvertent comma just before FROM. Try
this one (sorry for the numerous "back and forth" posts!):

SELECT Table1.Dept, Table1.G1, Table1.G2, Table1.G3,
(SELECT Avg(T.G1) FROM Table1 AS T

Hi Ken:

Thanks for your continuing helps. Actually what I need to do is add top
quarter value to an existant report. This is the reason I need to calculate
the mean of raw data grouped by Dept. Then I need to use formula 75th
percentile=(Sum([M1])/Abs(Sum([M1]>0))+ 0.674*(Stdv(IIf([M1]=0,Null,[M1])) (I
tried to exclude zeros). After added with this formula, it takes a long time
to run the report. The original report includes Percentage, Average.

If I create a separate query, can I use two queries for the same report? If
can, could you tell me how I can hook up two queries to ONE report?
Sincerely thank you very much.

Charles

Hi Ken:

Sorry for having delayed to get back to you. I have been busy with another
project and haven't got a chance to check this news group.

I copied your statement to SQL screen again but got the same error
message.
The statement on the screen:
SELECT Table1.Dept, Table1.G1, Table1.G2, Table1.G3,
(SELECT Avg(T.G1) FROM Table1 AS T
WHERE T.Dept = Table1.Dept) AS M1,
(SELECT Avg(U.G2) FROM Table1 AS U
WHERE U.Dept = Table1.Dept) AS M2,
(SELECT Avg(V.G3) FROM Table1 AS V
WHERE V.Dept = Table1.Dept) AS M3,
FROM Table1
GROUP BY Table1.Dept, Table1.G1, Table1.G2,
Table1.G3
ORDER BY Table1.Dept;

The error message:

The SELECT statement includes a reserved word or an argument name that is
misspelled or missing, or the punctuation isincorrect.

Sorry again to have bothered you some many times. I really appreciate your
help. Thanks a lot again.

Charles

As I have asked a number of times, you need to copy what you have in the
SQL
window and paste it back here in a message. I cannot see what you're
actually putting into the SQL window, and thus can't see if there is
something going wrong with the copying process.

After you get the error, copy what is in the SQL window and paste it
intoa
reply to this message....please.

Hi Ken:

I tried to create a new query. On the Query screen, I clicked New,
then
Design View, then SQL. Then I pasted the statement to that screen. But
an
another error prompted:

The SELECT statement includes a reserved word or an argument name that
is
misspelled or missing, or the punctuation is incorrect.

I am terribly sorry for having bothered you so many times. Is there
any
way
you could test on your Access program to see if there is anything I
did
not
follow correctly? Thank you so much.

Charles

"When I copied the statement to the Field ..."

I just realized what you're saying ... you have been posting my SQL
statement in the wrong place.

Let's start with a brand new query. Create a new query, don't select
any
tables, close the table window, click on view icon at top left of
toolbar
and select SQL, and paste the SQL statement that I posted into the
displayed
window (replace any text already there). Then try the query.

Hi Ken:

I am terribly sorry for this chronicle hassile. I tried it again
this
morning and got the following error messages:

When I copied the statement to the Field (either put M1: or not
prior
to
the
statement), the query window prompted an error message:

The syntax of the subquery in this expression is incorrect.
Check the subquery's syntax and enclose the subquery in
parentheses.

When I put a pair of parentheses ( ), immediately before the first
word
SELECT and immediately after the last word Table1 (semi column ;
disappeared
automatically), the query window prompted:

The expression you entered contains invalid syntax.
You may have entered an operand without an operator.

I know there may be other problem than the statement but I checked
the
Table1, variable Dept is text and G1, G2, G3 are all number. It
seems
everything is fine. But why the statement does not work. I
sincerely
appreciate your time in helping me with this. Thank you very much.

Charles

:

Either something is going wrong when you paste the SQL statement
into
your
query's window, or something about your setup is different from
what
I'm
understanding.

Post here the exact statement that your query says has an error
in
the
SQL
(don't post back what I posted, but rather what is in your
query's
window
when the error occurs).
