Hi SQL experts,

here's a simple one.  I need to extract the last 3 digits of a column, but the numbers of digits in each column varies.

Column:
111101
2202
333333303

Results to equal:  
101
202
303

How???

I've tried that, but it doesn't display consistently.

I tried left() and right() and it doesn't get the ideal output.

Here's the first query with a filter for a specific set of records
***Normal Return***

select sunitcode from tenant where hproperty = 170
 

sunitcode

6401101 

6401102 

6402211 

6402213 

6402214 

6402215 

6402216 
 

***With Right()***

select sunitcode=right(sunitcode,4) from tenant where hproperty = 170
 

101 

102 

211 

213 

214 

215 

216

1. it is char datatype ->
2. it is char(varchar,etc) datatype and data was pumped with  trailing blanks.
