Hi,
I have executed ANALYZE TABLE for myisam tables, but still myisam is showing
more scanning of rows as compared to innodb. What does ANALYZE TABLE command
exactly do for myisam storage engine.
Thanks

Hello,
Does anybody have any info on cross-database joins?
i.e. doing a join across various tables that are located inside different

Yes, Implemented and working fine

Hi,
There is nothing that, you can not enable log_slave_updates on slave.
Basically, it is useful in a situation when you have 1 master and 2 or more
slave in chain series. In this model 1st slave server should work as master
as well as slave. So, log_slave_update and binlog can be enabled to log

Hi All,
i set the skip-innodb in my.cnf, but when i do the below, it still shows
some default values assigned to innodb parameters, can i avoid this as there
is some amount of memory allocated to innodb, and i dont what that. I want
all resource to allocated to only myisam. Please let me know how
But, it also says, that if slave1 is made master and if log-slave-update is
set on it, then
slave2 might receive data that it might have arleady got from the old
master, which might cause errors like duplicate keys etc.

hi all, i have a question on insert ... select statement.
tbl_1(fld1,fld2,fld3, )
fld1 int primary key auto_increment not null
tbl_2(fld_a,fld_b,fld_c,...)
how do i construct my select statement so that fld1 is auto increment?
insert into tbl_1(fld1,fld2,fld3) select xxx, fld_b, NOW()
Hi Hiep,
you can put in either xxx = NULL
or you can skip it completely:
insert into tbl_1(fld2,fld3) select fld_b, NOW() from tbl_2;

Please actually read my reply before asking the same question. As I
stated, InnoDB outputs *estimated* row counts in EXPLAIN, whereas MyISAM
outputs *accurate* row counts.

This is something I do with replication.
You can replicate a list of tables, see the 'replicate_do_table' config
option.
Then you can euse the 'read_only' option. Replication still works but
nothing else. But it would give you more options by using GRANT instead
of 'read-only':

I'm currently deciding whether to build a decent sized (around

Up until version 5.0.44 (on linux) it appeared that you could do stuff

would be silently converted to an empty string. Similarly if you didn't

The beauty of this language is exactly as Johan says, you can skip the

the syntax is parallel (IMO), or alternatively to name the columns. But
