That should be $(echo "$T20 - $T120" | bc) since it is bash, not ksh93
Thanks a lot! Sorry i've forgotten to tell, that i'm using bash. And with
$(echo "$T20 - $T120" | bc)
it's working fine.
how can i extend the echo-term. finally i want to check in which range the difference is. So is it between 0 an 1, then print A. Is it between 1 and 2 print B.
Is it possible to construct this with a case-statement?
Thanks in advance!

oci_field_type(3) example

// Create the table with:
// CREATE TABLE mytab (number_col NUMBER, varchar2_col varchar2(1),
// clob_col CLOB, date_col DATE);

NOTES
Note
In PHP versions before 5.0.0 you must use ocicolumntype(3) instead. This name still can be used, it was left as alias of
oci_field_type(3) for downwards compatability. This, however, is deprecated and not recommended.

oci_num_fields(3), oci_field_name(3), oci_field_size(3).
