Numeric Operators in SQL Where clauses

Hi Das,

I am not sure why you would ever need to do this but it is possible as long
as you CAST the integer to a character type.

select cast(some_numeric_column as text) from some_table where
cast(some_numeric_column as text) like ‘8%’

would find all rows where “some_numeric_column” begins with 8. The more
common case would be:

select some_numeric_column from some_table where some_numeric_column >=80
and some_numeric_column < 90 You should be aware that if you have large datasets and you're doing a LIKE on a low-cardinality (lots of similar or same data) column, the query will do a table scan (evaluate all rows) and performance will suffer.
