Description
The RDO_FIELD_LEN() function is used to return the length of a field in a result set.
| Keywords | Description |
|---|---|
| <object> | Result set |
| <expN> | Column number |
Example
conn = rdo_connect("recital", "localhost", "?", "?","southwind") if conn > -1 res = rdo_query("select * from shippers", conn) for i = 0 to rdo_num_fields(res)-1 echo "table = ", rdo_field_table(res,i), "\n" echo "type = ", rdo_field_type(res,i), "\n" echo "name = ", rdo_field_name(res,i), "\n" echo "len = ", rdo_field_len(res,i), "\n" echo "flags = ", rdo_field_flags(res,i), "\n" next rdo_close(conn) endif
