The function sql-interactive-remove-continuation-prompt tries to
(string-match sql-prompt-regexp oline) and (string-match
sql-prompt-cont-regexp oline) but sql-prompt-regexp and
sql-prompt-cont-regexp default to nil. Reproducible from emacs -Q with
simply

(require 'sql)
(sql-interactive-remove-continuation-prompt "")


I got the bug when I tried using https://github.com/tumashu/sql-mssql
which uses sql.el, and presumably doesn't set these values. Maybe it
should, but it seems like sql.el would be more robust if it assumed they
could also have their default values :-)

Changing
                 (not (or (string-match sql-prompt-regexp oline)
                          (string-match sql-prompt-cont-regexp oline)))))

to

                 (not (or (and sql-prompt-regexp (string-match sql-prompt-regexp oline))
                          (and sql-prompt-cont-regexp (string-match sql-prompt-cont-regexp oline))))))

in sql-interactive-remove-continuation-prompt makes it work as expected
for me.
