columns from a join, equating foreign keys and otherwise equated columns.
this is also mostly to help inheritance scenarios formulate the best
choice of primary key columns. [ticket:185]
- added 'bind' argument to Sequence.create()/drop(), ColumnDefault.execute()
- added support for reflection of domains [ticket:570]
- types which are missing during reflection resolve to Null type
instead of raising an error
- moved reflection/types/query unit tests specific to postgres to new
postgres unittest module
[ticket:620]
- calling <column>.in_() (i.e. with no arguments) will return
"CASE WHEN (<column> IS NULL) THEN NULL ELSE 0 END = 1)", so that
NULL or False is returned in all cases, rather than throwing an error
[ticket:545]
LOB objects detected in a result set to be forced into OracleBinary
so that the LOB is read() automatically, if no typemap was present
(i.e., if a textual execute() was issued).
sized to the primary key constraint of the table. values that were
"passively" created and not available via cursor.lastrowid will be None.
- sqlite: string PK column inserts dont get overwritten with OID [ticket:603]
would not return selectable.c.col, if the selectable is a join
of a table and another join involving the same table. messed
up ORM decision making [ticket:593]
uses operator precedence to more intelligently apply parenthesis
to clauses, provides cleaner nesting of clauses (doesnt mutate
clauses placed in other clauses, i.e. no 'parens' flag)
- added 'modifier' keyword, works like func.<foo> except does not
add parenthesis. e.g. select([modifier.DISTINCT(...)]) etc.
enum's allowed range on insert and update, with strict=True
- Added new 'dialect' category of unit tests, and migrated MySQL-specific
dialect tests there.
- Noted the max identifier length in the MySQL dialect (the max alias length,
actually)
ASCII, UNICODE, and BINARY. support NATIONAL.
- added MySQL-specific reserved words
- added tests for MySQL numeric and string column DDL generation
- various minor cleanups, also tweak regex to not break emacs syntax hilighting
if table doesnt exist, in order to determine if a table exists.
this supports unicode table names as well as schema names. tested
with MySQL5 but should work with 4.1 series as well. (#557)
embedded select() statements against the table being updated or
deleted. this works the same as nested select() statement
correlation, and can be disabled via the correlate=False flag on
the embedded select().
