Problems with a MySQL server change - mysql

Question

I have three tables in MySQL:
CREATE TABLE `mlm`.`facturacion_2012_drm_base` ( `custid`
varchar(20) NOT NULL, `fecha` date NOT NULL, `docid` varchar(20)
NOT NULL, `billid` varchar(20) NOT NULL, `movimiento` varchar(20)
DEFAULT NULL, `movid` varchar(20) DEFAULT NULL, `medio_pago`
varchar(40) DEFAULT NULL, `digitos` varchar(20) DEFAULT NULL,
`monto_facturado` decimal(20,2) NOT NULL, `monto_pagado`
decimal(20,2) NOT NULL, `monto_usado` decimal(20,2) NOT NULL,
`documento` varchar(2) NOT NULL, `codigo_pago` varchar(5) DEFAULT
NULL, `desc_pago` varchar(100) DEFAULT NULL, `sociedad`
varchar(45) DEFAULT NULL, `sociedad_bonif` varchar(45) DEFAULT NULL,
KEY `billid` (`billid`), KEY `motors_no_fact`
(`custid`,`billid`,`fecha`,`documento`) USING BTREE, KEY
`facturacion` (`custid`,`fecha`,`documento`) USING BTREE )
ENGINE=MyISAM DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC;
CREATE TABLE `mlm`.`facturacion_2012_drm_cortes` ( `id` bigint(20)
NOT NULL AUTO_INCREMENT, `fecha_inicial` date NOT NULL,
`fecha_final` date NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM
AUTO_INCREMENT=433 DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC;
CREATE TABLE `mlm`.`facturacion_2012_drm_emitidas` ( `id`
bigint(20) NOT NULL AUTO_INCREMENT, `custid` varchar(20) NOT NULL,
`fecha_emision` date NOT NULL, `id_fechas` bigint(20) NOT NULL,
`monto` decimal(20,2) NOT NULL, `iva` decimal(20,2) NOT NULL,
`total` decimal(20,2) NOT NULL, `medio_pago` varchar(2000) NOT NULL,
`digitos` varchar(100) NOT NULL, `operaciones` int(10) NOT NULL,
`activa` varchar(2) NOT NULL, `movimiento` varchar(45) NOT NULL,
`parcialidades` varchar(100) NOT NULL, `monto_bruto` decimal(20,2)
NOT NULL, `billid` varchar(45) NOT NULL, `serie` varchar(2)
DEFAULT NULL, `folio` int(10) DEFAULT NULL, `uuid` varchar(45)
DEFAULT NULL, PRIMARY KEY (`id`), KEY `motors`
(`billid`,`id_fechas`,`activa`) ) ENGINE=MyISAM AUTO_INCREMENT=511483
DEFAULT CHARSET=latin1;
I changed the MySQL server from 5.1 (32 Bits) to 5.6 (64 Bits) and restored all my tables but I´m having problems with this query:
SELECT a.custid,
a.monto_facturado,
a.billid,
a.fecha,
b.id,
b.fecha_inicial
FROM facturacion_2012_drm_base a,
facturacion_2012_drm_cortes b
WHERE a.custid = ANY (SELECT custid
FROM facturacion_motors_pendientes
WHERE situacion = 'no facturado')
AND a.billid <> ALL (SELECT billid
FROM facturacion_2012_drm_emitidas
WHERE activa = 'SI')
AND a.fecha BETWEEN b.fecha_inicial AND b.fecha_final
AND a.documento = 'FA'
AND Year(a.fecha) = Year(Curdate())
GROUP BY a.billid
Since the server change, the query never finish, showing the message "Query is being executed..."
Anybody knows why this is happening?

Answer 1

At the very least you have indexing problems:
On facturacion_2012_drm_emitidas you filter by activa but do not have an index that can be used for this
On facturacion_2012_drm_base you don't have an index for fecha or documento that can be used
On facturacion_2012_drm_cortes you don't have an index for fecha_inicial or fecha_final
I don't know if you have index problems on facturacion_motors_pendientes because you did not include DDL for it.
Make sure you have the proper indexes for your query and then see what happens. What is happening now is that you have a complex join with subqueries and basically none of it is utilizing indexes, requiring you to execute full table scans on all tables involved.
You also might consider converting these tables to InnoDB, as that is the preferred table type in 5.6. This is of course unless you need certain MyISAM functionality on these tables (like full text search).
