What version of Flyway are you using?


What database are you using (type & version)?

Oracle 11g / 12c

What operating system are you using?

Windows 7

What did you do?

After updating to flyway 4.0 some stored procedures started to fail compilation when updated through flyway.
Managed to track problem to following

Test script to reproduce the issue

create or replace procedure Test_proc
    EXECUTE IMMEDIATE 'SELECT 123 num, 321 num2 '||'/*comment with,comma'||'*/ from dual order by num, num2';
end Test_proc;

the problem seems to be:
parser splits '/*comment with,comma' into several tokens, one of them is '/*comment
when it is handled by following piece of code inside SqlStatementBuilder

            if (cleanToken.contains("/*")) {
                handled = true;
            } else if (cleanToken.startsWith("'")) {
                handled = true;

' is ignored and as a result number of quotes is uneven.

which ultimately leads to
PLS-00103: Encountered the symbol "/" The symbol "/" was ignored.


modify method protected String simplifyLine(String line) in SqlStatementBuilder to add spaces around quotes(both ' and alternative) and may be around multiline comments /* */
or consider using regex to find required special tokens instead of splitting string
