Converison to numeric type ?
Have a field 'amsl' of type text, with empy string in it
(CASE WHEN amsl = '' then NULL else (TRIM(REPLACE(amsl,'meters',''))*1) end) as amsl1
Should not then there be Null if source data is '' ? Instead I get 0.
btw, if I do
(CASE WHEN amsl = '' then '' else (TRIM(REPLACE(amsl,'meters',''))*1) end) as amsl1
