Question

CF8

I was using this line to get the MIN value of a query column. I just noticed a null value in a recordset causes an error. Is there a simply way to tell ArrayMin to skip nulls w/o having to loop the column and load an array with all non-null values?

<cfset temp_data_min = #round(ArrayMin(query_x["some_field"]))#>

thanks!

You could loop through your array and create a new array that doesn’t contain any null values. Then apply the ArrayMin function to the new array.

<cfset newArray = []>
<cfloop index="x" array="#query_x["some_field"]#">
  <cfif x NEQ 'null'>
      <cfset arrayAppend(newArray, x)>
  </cfif>
</cfloop>
<cfset temp_data_min = round(ArrayMin(newArray))>
