As Robert mentioned, we do "SET SQL_MODE='POSTGRESQL'" when using MySQL.
This is equivalent to the "PIPES_AS_CONCAT" directive Ghada mentioned,
as well as several other options:
Equivalent to PIPES_AS_CONCAT, ANSI_QUOTES, IGNORE_SPACE,
NO_KEY_OPTIONS, NO_TABLE_OPTIONS, NO_FIELD_OPTIONS.

Title:
MySql concat string needs to be used instead of ||
Status in Mahara:
Won't Fix
Bug description:
Mahara 15.10
OS: Ubuntu 14.04
DB: Mysql 5.5
Browser: any
I've noticed that in htdocs/search/internal/lib.php, the SQL used to
concatenate strings is '||'.
For example, line 275:
$sql = $alias . '.' . $field . ' ' . db_ilike() . " '%' || ? || '%'";
Unfortunately, this doesn't always work with Mysql. In order for this to work
we would need to set PIPES_AS_CONCAT
Please refer to the documentation:
http://dev.mysql.com/doc/refman/5.7/en/sql-mode.html#sqlmode_pipes_as_concat
Otherwise, strings need to be concatenated using: 'CONCAT'.
This function is also available in Postgres.
So, perhaps we should be using CONCAT instead of '||'.
So, the above line 275 would be:
$sql = $alias . '.' . $field . ' ' . db_ilike() . " concat('%', ? , '%')";
