Linq query using contains is not working

Question

I would like to use a query in LINQ and use a function that works like \"LIKE\" in TSQL. For example:

 SELECT salary 
 FROM employees 
 WHERE last_name LIKE \'R%         


        

Answer 1

Contains should work as it checks for a substring. It is equal to executing the sql statement where BI_FORMAT_NAME LIKE '%Tom%'

But if need records for LIKE 'Tom%' condition, You may use StartsWith method.

where  P.BI_FORMAT_NAME.StartsWith("Tom")

It should work as long as your LINQ query without the where clause is returning records with BI_FORMAT_NAME column has values like "Tom" or "TomSomeThingElse"

The LINQ methods for different SQL likeclause use cases are

1. LIKE '%To%' --> Contains("To")
2. LIKE 'Tom%' --> StartsWith("Tom")
3. LIKE '%Tom' --> EndsWith("Tom")
