I have the following TSQL,
select 2*EC.Total C1, T1.C2, EC.Total
FROM MyTable1 T1
OUTER APPLY (select COUNT(*) AS Total from MyTable2 T2 WHERE T1.SomeColumn=T2.SomeColumn ) EC
ORDER BY EC.Total desc
I need to convert this to Oracle 11g. I tried lateral but not supported.
You don't really need a lateral join there:
select 2*EC.Total C1, T1.C2, EC.Total
FROM MyTable1 T1
LEFT JOIN (
select m2.somecolumn, COUNT(*) AS Total
from MyTable2 m2
group by m2.somecolumn
) ec ON t1.somecolumn = ec.somecolumn
ORDER BY EC.Total desc
