Discussion

The function A5_FIELD_INFO() returns information about a field in a table. The table does not have to be open.

Example

? a5_field_info("customer", "lastname")
= decimals = 0.000000
Longtype = "Character"
name = "lastname"
Shorttype = "C"
width = 20.000000

Note : There are several ways to get info about a field. If the table is open then you can get a pointer to a field and use the <FIELD>.TYPE_GET()and <FIELD>.WIDTH_GET()methods of the field object.

t = table.open("customer")
f = t.field_get("firstname")
? f.type_get()
= "C"
? f.width_get()
= 20.000000
t.close()

If the table is closed, you can also use the TABLE.EXTERNAL_FIELD_NAME_GET()method to return a CR-LF delimited string of info about ALL of the fields in the table. The advantage of A5_FIELD_INFO() is that it works on a table that does not have to be open, and you do not have to extract the info from a long string that is returned by the TABLE.EXTERNAL_FIELD_NAME_GET() method.
