Hello

 

 

I\'m sorry if this question seems \"noobish\" but I can\'t figure it out

 

 

I have 2 tables

 

we will call them table1 and table2

 

I use this query


SELECT 1.blah, 2.id, 1.number FROM table1 1, table2 2  WHERE 2.id = "X" AND 1.blah = "X"

------------------------

id - blah - number

----------------------

X - X - 3.00

X - X - 4.00

X - X - 7.00

X - X - 4.00

 

I would like to add all of the numbers to give me one value I can use

 

can anyone help?

thank you

I get this error when using your query

 

#1140 - Mixing of GROUP columns (MIN(),MAX(),COUNT()...) with no GROUP columns is illegal if there is no GROUP BY clause

 

 

this is the exact query I used


SELECT m.clan, SUM(m.strength) FROM members m, clan c  WHERE c.id = "1" AND m.clan = "1"

 

 

when the I get this working for c.id = 1 and m.clan = 1 then both of the 1\'s become variables, since there are multiple clans and multiple members

Soory about missing the group by. This will give total for blah = X

 

SELECT 1.blah, SUM(1.number )

FROM table1 1, table2 2

WHERE 2.id = 1.blah

AND 1.blah = \"X\"

GROUP BY 1.blah

 

and this gives totals for all blahs

 

SELECT 1.blah, SUM(1.number )

FROM table1 1, table2 2

WHERE 2.id = 1.blah

GROUP BY 1.blah

thanks, in PHPmyAdmin it out puts what I want to see

 

 


SELECT m.clan, SUM(m.strength) FROM members m, clan c  WHERE c.id = "1" AND m.clan = "1" Group By m.strength

 

I made a php page in hopes to output m.strength

 

but it didn\'t do it


<?php

mysql_pconnect("*****","*****","*******");

mysql_select_db("Clan");



$Tstrength = mysql_query("SELECT m.clan, SUM(m.strength) FROM members m, clan c  WHERE c.id = "1" AND m.clan = "1" Group By m.strength");



print  "$Tstrength";

?>

this does not out put a number it outputs

Resource id #3

 

which really confuses me since no members have an ID of 3,

Humm!!

 

Resource ID is something which the mysql_query. See the manual for more details.

 

 

<?php 

mysql_pconnect("*****","*****","*******"); 

mysql_select_db("Clan"); 



$Tstrength = mysql_query("SELECT m.clan, SUM(m.strength) FROM members m, clan c  WHERE c.id = "1" AND m.clan = "1" Group By m.strength"); 



while ($row = mysql_fetch_array($Tstrength))

{ 

echo $row[0];

echo $row[1];

}

?>

  • 2 weeks later...

<?php 

mysql_pconnect("*****","*****","*******"); 

mysql_select_db("Clan"); 



$Tstrength = mysql_query("SELECT m.clan, SUM(m.strength) FROM members m, clan c  WHERE c.id = 1 AND m.clan = 1 Group By m.strength"); 



while ($row = mysql_fetch_array($Tstrength))

{ 

print" Strength:  $row[1]";

}

?>

 

this code works great

if

c.id and m.clan are numbers, but I need them to be a variable

 

I tried

WHERE c.id =$clan[id] AND m.clan =$clan[id]

 

but I get

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/virtual/site55/fst/var/www/html/game/clan.php on line 163

 

any ideas?

 

what I need is to beable to see the users clan[id]\'s to determin the strength of said clan

the site uses sessions,

if some one is truely interested in troubleshooting with me beyond forum posts I\'ll show the enite source code to you give you a better understanding of what I\'m trying to do
