what it will return if key not found in lookup table
Hi Firneds
I have few odscodes in Lookup table named "AllowLT" .
Now I need to continue if I found value in lookup table or stop it. For that I have colleting the value form lookup table for input HL7 message OBR:21 value.
I know if found in lookup table it will return 1 or 0 . If not found what it will return below line? to return 0 in case , given key not available in lookup table , what I need to write?
if isallowed=1
{
}
else
{
}
