How to loop form values depending on form column name? - coldfusion

Question

I have a form containing 6 check_num fields, 1 account number and an amount. I would like to insert those values into a database table:
<cfquery datasource="test" name="test">
insert into test (ACCOUNT_NUMBER,check_num,amount)
values ('#ACCOUNT_NUMBER#','#check_num#','#amount#')
</cfquery>
However, I don't want to insert all of the values into 1 row. If any of the check_num fields contain a number, I want to insert that value, along with with the acccount_number and amount values.
For example with the data below, I would like to insert 5 rows. The field "check_num6" would be skipped because it is empty.
ACCOUNT_NUMBER 123456789
CHECK_NUM1 56623
CHECK_NUM2 5512
CHECK_NUM3 6562
CHECK_NUM4 653
CHECK_NUM5 6623
CHECK_NUM6
AMOUNT 32.31
FIELDNAMES ACCOUNT_NUMBER,CHECK_NUM1,CHECK_NUM2,CHECK_NUM3,CHECK_NUM4,CHECK_NUM5,CHECK_NUM6,AMOUNT,SUBMIT
SUBMIT Submit

Not perfect but you can start/get some inspiration from here:
<cfloop list="#StructKeyList(form)#" index="i">
<cfif (left('#i#', 9) is "CHECK_NUM") and (trim(form['#i#']) is not "")>
<cfquery datasource="test" name="test">
insert into test (ACCOUNT_NUMBER,check_num,amount)
values ('#ACCOUNT_NUMBER#','#form['#i#']#','#amount#')
</cfquery>
</cfif>
</cfloop>
Also you should validate, see if your DB supports multiple inserts, change your query to use cfqueryparam, research about it. So, a better cfquery code would be:
<cfquery datasource="test" name="test">
insert into test (
ACCOUNT_NUMBER,
check_num,
amount
)
values (
<cfqueryparam cfsqltype="cf_sql_varchar" value="#form.ACCOUNT_NUMBER#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#form['#i#']#">,
<cfqueryparam cfsqltype="cf_sql_varchar" value="#form.amount#">
)
</cfquery>
