>Description: The following query results in a different # of rows if the sql_big_tables is set to 1:
select count(incidents.ref_no) from incidents, labels where incidents.ref_no like '020531%' group by labels.label, incidents.ref_no; The query seems unusual because it was a lot more complicated but I broke it down for better readability. incidents.refno is [varchar(15) binary] eg '020531-000031' labels.label is [blob] eg 'Pricing' Note: The results are only different if there is a large # of results from the query >How-To-Repeat: create two tables with the above attributes and of large size. Then run the query with sql_big_tables set to 1 and when it's not set. >Fix: Code fix? >Submitter-Id: <submitter ID> >Originator: RightNow Techmologies >Organization: RightNow Technologies >MySQL support: [ extended email support ] >Synopsis: sql_big_tables option changes results when set for some queries > >Severity: >Priority: >Category: mysql >Class: >Release: mysql-3.23.47 (Source distribution) >Environment: System: Linux dbsc01.rightnowtech.com 2.4.17 #2 SMP Fri Jan 4 17:47:51 EST 2002 i686 unknown Architecture: i686 Some paths: /usr/bin/perl /usr/bin/make Compilation info: CC='gcc' CFLAGS='-O3 -mpentiumpro' CXX='gcc' CXXFLAGS='-O3 -mpentiumpro -felide-constructors -fno-exceptions -fno-rtti' LDFLAGS='' LIBC: lrwxrwxrwx 1 root root 13 Oct 15 2000 /lib/libc.so.6 -> libc-2.1.3.so -rwxr-xr-x 1 root root 4103980 Jul 31 2000 /lib/libc-2.1.3.so Configure command: ./configure --prefix=/usr/local/pkg/mysql/mysql-3.23.47 --enable-assembler --with-mysql-ldflags=-all-static --disable-shared --with-extra-charsets=complex --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
