Upgrading fomr MySQL to MariaDB, stored procedure with union

You are viewing an old version of this question. View the current version here.

Hello all,

I'm new here and to MySQL/MariaDB. Now changed jobs and have to work MySQL/MariaDB.

The first thing is to check upgrading MySQL 5.6.23 to MariaDB 10.3.9. So took a backup from the MySQL db ( a sql 8.8GB )

Now the scripts stops at creating a store procedure with a select - union in it. From the backup script:

CREATE DEFINER=`root`@`%` PROCEDURE `sp_s_persoon_bedrijf_werknemer`(
  IN  In_param1  varchar(30),
  IN  in_param2  varchar(30),
  IN  in_param3  varchar(30),
  IN  in_param4  varchar(30),
  IN  in_param5  varchar(30),
  IN  in_param6  varchar(30)
)
BEGIN
select * from `v_bedrijf`          
where (zoekveld like concat('%',in_param1,'%') or in_param1 = '')
and   (zoekveld like concat('%',in_param2,'%') or in_param2 = '')
and   (zoekveld like concat('%',in_param3,'%') or in_param3 = '')
or    (zoekveld like concat('%',in_param4,'%') and in_param4 <> '')
or    (zoekveld like concat('%',in_param5,'%') and in_param5 <> '')
or    (zoekveld like concat('%',in_param6,'%') and in_param6 <> '') limit 1000
union
select * from `v_personen`          
where (zoekveld like concat('%',in_param1,'%') or in_param1 = '')
and   (zoekveld like concat('%',in_param2,'%') or in_param2 = '')
and   (zoekveld like concat('%',in_param3,'%') or in_param3 = '')
or    (zoekveld like concat('%',in_param4,'%') and in_param4 <> '')
or    (zoekveld like concat('%',in_param5,'%') and in_param5 <> '')
or    (zoekveld like concat('%',in_param6,'%') and in_param6 <> '')  limit 1000
union
select * from `v_werknemer`          
where (zoekveld like concat('%',in_param1,'%') or in_param1 = '')
and   (zoekveld like concat('%',in_param2,'%') or in_param2 = '')
and   (zoekveld like concat('%',in_param3,'%') or in_param3 = '')
or    (zoekveld like concat('%',in_param4,'%') and in_param4 <> '')
or    (zoekveld like concat('%',in_param5,'%') and in_param5 <> '')
or    (zoekveld like concat('%',in_param6,'%') and in_param6 <> '')  limit 1000
;

END ;;

Just complains with: SQL Fout (1064): You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'unionselect * from `v_personen` where (zoekveld like concat('%',in_' at line 17

Some searching and trying found out there has to be () round the select statements. But also have to remove the Begin/End from the script. This seems strange to me.... Can someone explain?

I used MySQLWorkbench and Heidi for the small part of the script.

Kind reagrds,

Jan

Answer

This appears to work fine, with no need to remove the BEGIN or END:

CREATE OR REPLACE DEFINER=`root`@`%` PROCEDURE `sp_s_persoon_bedrijf_werknemer`(
  IN  In_param1  varchar(30),
  IN  in_param2  varchar(30),
  IN  in_param3  varchar(30),
  IN  in_param4  varchar(30),
  IN  in_param5  varchar(30),
  IN  in_param6  varchar(30)
)
BEGIN
(select * from `v_bedrijf`          
where (zoekveld like concat('%',in_param1,'%') or in_param1 = '')
and   (zoekveld like concat('%',in_param2,'%') or in_param2 = '')
and   (zoekveld like concat('%',in_param3,'%') or in_param3 = '')
or    (zoekveld like concat('%',in_param4,'%') and in_param4 <> '')
or    (zoekveld like concat('%',in_param5,'%') and in_param5 <> '')
or    (zoekveld like concat('%',in_param6,'%') and in_param6 <> '') limit 1000)
union
(select * from `v_personen`

and   (zoekveld like concat('%',in_param2,'%') or in_param2 = '')
and   (zoekveld like concat('%',in_param3,'%') or in_param3 = '')
or    (zoekveld like concat('%',in_param4,'%') and in_param4 <> '')
or    (zoekveld like concat('%',in_param5,'%') and in_param5 <> '')
or    (zoekveld like concat('%',in_param6,'%') and in_param6 <> '')  limit 1000)
union
(select * from `v_werknemer`

and   (zoekveld like concat('%',in_param2,'%') or in_param2 = '')
and   (zoekveld like concat('%',in_param3,'%') or in_param3 = '')
or    (zoekveld like concat('%',in_param4,'%') and in_param4 <> '')
or    (zoekveld like concat('%',in_param5,'%') and in_param5 <> '')

END;
