I have a table with five columns. Only one of first four column will have a value and other will be null at a time and I need to get that non-null value from the table row with check on fifth column. Below sql statement working fine as per my requirement. But I need to do same using LINQ. Please suggest how can I achieve same using LINQ? or Equivalent LINQ statement?
SELECT
CASE
WHEN col1 is not null THEN col1
WHEN col2 is not null THEN col2
WHEN col3 is not null THEN col3
WHEN col4 is not null THEN col4
END
FROM MyTable where col5 ='abc'
First thing first. Your sql is not correct. It has to be SELECT COALESCE(col1,col2,col3,col4) AS COL FROM MyTable where col5 ='abc'
.
var myObj = db.MyTable.Where(s => s.Col5 == 'abc').Select(s=> new {COL = s.col1??s.col2??s.col3??s.col4??"" })
