select adv
from indata
where inid = '$INSTRUID'
and Date = (
select max(Date)
from indata
where inidi = '$INSTRUID'
limit 1
)
limit 1;
Or:
Code:
select a.adv
from indata a
join (
select inid, max(Date) Date
from indata
where inid = '$INSTRUID'
group by inid
) b
on a.inid = b.inid
and a.Date = b.Date
where a.inid = '$INSTRUID'
limit 1
;
I've added the limit clause for safety (not knowing your table structure and data, it's impossible to know if duplicates are possible).
Hi there,
I have a hierarchical database that include 4 tables. Table A is the parent of B, B is Parent of C, C is parent of D. If I want to query everything in D that is associated with A.name, how do I do that? Thanks!

dbix::searchbuilder::handle::mysql
DBIx::SearchBuilder::Handle::mysql(3pm) User Contributed Perl Documentation DBIx::SearchBuilder::Handle::mysql(3pm)NAME
DBIx::SearchBuilder::Handle::mysql - A mysql specific Handle object
SYNOPSIS DESCRIPTION
This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of MySQL.
METHODS
Insert
Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.
If the insert succeeds, returns the id of the insert, otherwise, returns a Class::ReturnValue object with the error reported.
SimpleUpdateFromSelect
Customization of "SimpleUpdateFromSelect" in DBIx::SearchBuilder::Handle. Mysql doesn't support update with subqueries when those fetch
data from the table that is updated.
DatabaseVersion
Returns the mysql version, trimming off any -foo identifier
CaseSensitive
Returns undef, since mysql's searches are not case sensitive by default
SimpleDateTimeFunctions
Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.
ConvertTimezoneFunction
Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.
Use the following query to get list of timezones:
SELECT Name FROM mysql.time_zone_name;
Read docs about keeping timezone data up to date:
