I am writing a sql server query with one column as a expression like

```
Select name , name + age as Test from myTable
where Test like '%b%';

```

Now i cannot use Test either i need to write 

```
Select name , name + age as Test from myTable
where (name + age) like '%b%';

```

Now the expression (name + age) can be very big sometimes so cant i give it some alias and use it

Any help is appreciated,

Thank You
