DatabaseIndex

This takes a variable number of parameters, each of which is a column for indexing. Each column may be a column object or the string name of the column (not the database name). You may also use dictionaries, to further customize the indexing of the column. The dictionary may have certain keys:

'column':
The column object or string identifier.
'length':
MySQL will only index the first N characters if this is given. For other databases this is ignored.
'expression':
You can create an index based on an expression, e.g., 'lower(column)'. This can either be a string or a sqlbuilder expression.

Further keys may be added to the column specs in the future.

The class also take the keyword argument unique ; if true then a UNIQUE index is created.

Methods

f __format__(...) ...

default object formatter

f __subclasshook__(...) ...

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

f __sizeof__(...) ...

__sizeof__() -> int size of object in memory, in bytes

f __init__(self, *columns, **kw) ...

f setName(self, value) ...

f withClass(self, soClass) ...
