This bug will surface when using the ORM and adding an join to DataList
where a DataObject inherits another DataObject.
If you for example want to restrict the number of pages that only have a
related Staff object:
$list = DataList::create('Page')
->InnerJoin('Staff', '"Staff"."ID" = "Page"."StaffID");
This will create a SQL query where the INNER JOIN is before the
LEFT JOIN of Page and SiteTree in the resulting SQL string. In MySQL
and PostgreSQL this will create an invalid query.
This patch solves the problem by sorting the joins.
Quoted table / column names to make test cases work in postgres
BUG Fixed issue with SQLQuery::lastRow crashing on empty set. Added test cases for lastRow and firstRow.
Quoted table / column names to make test cases work in postgres
Merge branch '3.0-sqlquery-lastrow-fix' of github.com:tractorcow/sapphire into 3.0-sqlquery-lastrow-fix
The entire framework repo (with the exception of system-generated files) has been amended to respect the 120c line-length limit. This is in preparation for the enforcement of this rule with PHP_CodeSniffer.
This bug was caused by the fact that SQLQuery::whereAny() removed existing filters. In line with addWhere() and setWhere(), I split this into addWhereAny() and setWhereAny(). Strictly speaking, this drops the method SQLQuery::whereAny(), but it was really just an internal function for exclude, and so I think that's acceptable.

The primary goal of this branch was to fix the sort bugs in AssetAdmin, however, it started a bit of a yak shave in that the API around SQLQuery was poor. The biggest change that this pull request makes is it changes the format of SQLQuery::$select to contain aliases as array keys (and consistently puts the "implicit alias" in there to assist with various query generation logic), but it also makes a bunch of changes to avoid direct access of that property.
API CHANGE: Deprecated SS_List::getRange() in favour of SS_Limitable::limit().
API CHANGE: Introduce SS_Limitable::limit($limit, $offset = 0) as the only modern way of specifying limits; deprecate all others.
API CHANGE: augmentSQL is now passed a DataQuery object from which query parameters can be extracted.
API CHANGE: DataObjectDecorators that manipulate the query can now define augmentDataQueryCreation().
API CHANGE: The container class argument for DataObject::get() is deprecated.
API CHANGE: DataObject::buildSQL() and DataObject::extendedSQL() are deprecated; just use DataObject::get() now.
API CHANGE: DataObject::instance_get() and DataObject::instance_get_one() are deprecated, and can no longer be overloaded.
API CHANGE: DataObject::buildDataObjectSet() is deprecated.
API CHANGE: Cant't call manual manipulation methods on DataList such as insertFirst()
