# title:        Builtin functions converting binary string to hexadecimal representation and vice versa
# decription:
#                   Test may need to be more complex. Currently only basic operations are checked:
#                   * ability to insert into binary field result of hex_decode()
#                   * result of double conversion: bin_data -> base64_encode -> base64_decode
#                     - must be equal to initial bin_data (and similar for bin_data -> hex_encode -> hex_decode)
#                   We get columns type details using sqlda_display in order to fix them in expected_stdout.
#
#                   Checked on 4.0.0.1496: OK, 1.679s.
