GetFieldName(Customer::FirstName)¶GetFieldName(Customer::LastName)¶GetFieldName(Customer::Address)

Customer::FirstName¶LastName¶Customer::Address

Sample output:

All the above returns the same output:

"FirstName","LastName","Address"

Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Let ([
    line = GetValue(FieldNameList;1);
    pos =Position( line; "::"; 1;1);
    result = "\"" & If(pos=0;  line ; Right( line; Length(line) - pos -1) ) & "\"";
    rest = MiddleValues (FieldNameList; 2; ValueCount(FieldNameList) -1)
    ];
    If(IsEmpty(rest); result; result & "," & FieldList4SQL(rest) )
)

This function is mainly used for my own sql lookup function, so that it can return multiple fields. It can be done by hand crafting the return field name, but I'd rather using a function like this to automatically generated the field list between "SELECT" and "FROM". I use GetFieldName( ) a lot, which always have table name. So this function also strip out the "tablename::" for each line.
