# title: Invalid computed by definition generated by isql -x
# decription:
# We create table and then run ISQL with '-x' key and saving its output to file.
# This operation should NOT produce any error (see var. 'f_xmeta_err').
# Then we drop table and run ISQL again but for APPLYING extracted metadata.
# If "ISQL -x" will produce script with invalid syntax, compiler will raise error.
# Test checks that:
# 1) table is recreated successfully and consists of the same fields as before;
# 2) compiler STDERR (see var. 'f_apply_err') is empty.
# Confirmed:
# 1) wrong metadata generation on 4.0.0.130
# 2) works fine on 4.0.0.132, 3.0.0.32474
