Hello
Could you tell me how to write ``like s.col1 || '%'`` join statement with
sequel?
I would like to write following query with sequel.
I wrote it except ``like join`` statement.
* DB: PostgreSQL 9.4.5
* Sequel: 4.28.0
Thank you for your advice.
SELECT col1, col2,count(*)
FROM ( SELECT s.col1,col2
FROM data_table1 l,
rel_table s
WHERE l.path like s.col1 || '%'
UNION ALL
SELECT s.col1,col2
FROM data_table2 l,
rel_table s
WHERE l.path like s.col1 || '%'
) as test GROUP BY col1,col2;
db[:data_table1].select(:col1,:col2)
.union(db[:data_table2].select(:col1,:col2),:all=>true)
.group_and_count(:col1,:col2)
