# title: ISQL: bad headers when text columns has >= 80 characters
# decription:
# Test creates .sql script with query that contains literal (similar to descriped in the ticket, but much longer).
# Then we parse result of this query and compare length of header and data. They both must be equal to the same value.
# Confirmed truncated length of header on 4.0.0.2225
# Checked on 4.0.0.2249 - all fine.
