Description

The RDO_FETCH_FIELD() function is used to return an object containing information about a field from a result set. If the column number, <expN>, is omitted, the result of the previous RDO_FIELD_SEEK() is used.

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
        arr1 = rdo_fetch_field(res,i)
        print_r(arr1)
    next
    rdo_close(conn)
endif
