Hi, I have a simple function that searches for a user (see below).
using cfscript. cf2016
I want to have the “username” parameter in the WHERE optional.
So traditionally I have:
Wrapped the where clause in IF statements to check if a Parameter is
So this works just fine but gets a little cumbersome and hard to read,
however with optional parameters I figure I am going to have to build my SQL
statement dynamically in any case. I have several parts to this question:
1 – Is there a cleaner solution apart from building the SQL string
2 – Would it be bad practice to pass the whole built SQL string as a
parameter to this function, the entire select statement being built outside of
3- Depending on the above answers would it then be an option to simply
create a function to run any SQL command..
General best-practice for designing functions suggests that you:
1) only include in the function body the parts that will remain fixed, for example, the SELECT query;
2) bring in the changing parts as arguments to the function, for example, the WHERE clauses.
