I have two tables "tags" and "deal_tag", and table definition follows,
Table('tags', metadata,
Column('id', types.Integer(), Sequence('tag_uid_seq'),
primary_key=True),
Column('name', types.String()),
)
Table('deal_tag', metadata,
Column('dealid', types.Integer(), ForeignKey('deals.id')),
Column('tagid', types.Integer(), ForeignKey
('tags.id')),
)
I want to select tag id, tag name and deal count (number of deals per
tag).
I tried to create the query in sqlalchemy select function
select([tags_table.c.name,tags_table.c.id, func.count
(deal_tags_table.c.dealid).label('dealcount')],join(tags_table,
deal_tags_table),group_by=[deal_tags_table.c.dealid])
select function creates query linke this
SELECT tags.name, tags.id, count(deal_tag.dealid) AS dealcount FROM
tags JOIN deal_tag ON tags.id = deal_tag.tagid WHERE tags JOIN
deal_tag ON tags.id = deal_tag.tagid GROUP BY deal_tag.dealid
But my excepted query is
SELECT tags.Name,tags.id,COUNT(deal_tag.dealid) FROM tags INNER JOIN
deal_tag ON tags.id = deal_tag.tagid GROUP BY deal_tag.tagid;
Please help me
