>Description: When i want to find the next unused id from a table joining it whith another table the result is allways 1, even though this is not correct >How-To-Repeat: create table a (id int not null primary key); create table b (id int not null primary key); insert into a values (1),(2),(3),(4),(5),(6),(7),(8); insert into b values (1),(2),(3),(5),(6); select min(a.id) from a left join b on a.id = b.id where b.id is null; +-----------+ | min(a.id) | +-----------+ | 1 | +-----------+ >Fix: The problem can be fixed whith the following select select min(a.id) from a left join b on a.id = b.id where b.id is null and a.id is not null; +-----------+ | min(a.id) | +-----------+ | 4 | +-----------+ even though the a.id never is null. >Submitter-Id: <submitter ID> >Originator: >Organization: ----------------------------------------------------- / \ | Ole Lund Jensen | | Groenjordsvej 1, st., -1114 | | DK-2300 Koebenhavn S | | Tlf.: (+45) 32 87 60 13 | | e-mail: [EMAIL PROTECTED] | \ / ----------------------------------------------------- > >MySQL support: none >Synopsis: ?? >Severity: non-critical >Priority: low >Category: mysql >Class: sw-bug >Release: mysql-3.23.36 (Source distribution) >Environment: System: OSF1 gram V4.0 878 alpha Architecture: alpha Machine: alpha Some paths: /usr/local/bin/perl /usr/bin/make /usr/local/bin/gmake /usr/local/bin/gcc /usr/bin/cc GCC: Reading specs from /usr/local/lib/gcc-lib/alpha-dec-osf4.0d/2.95.2/specs gcc version 2.95.2 19991024 (release) Compilation info: CC='cc -pthread -std1' CFLAGS='' CXX='cxx -pthread -O' CXXFLAGS='' LDFLAGS='' LIBC: lrwxrwxrwx 1 root system 17 Jul 5 1998 /lib/libc.a -> ../ccs/lib/libc.a lrwxrwxrwx 1 root system 17 Jul 5 1998 /usr/lib/libc.a -> ../ccs/lib/libc.a Configure command: ./configure '--with-named-thread-libs=-lpthread -lmach -lexc -lc' --with-low-memory --enable-large-files --prefix=/var/mysql/v3.23.36 --with-mysqld-ldflags=-all-static -disable-shared Perl: This is perl, version 5.004_04 built for alpha-dec_osf --------------------------------------------------------------------- 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?
