Subject [Solution]: error loading a mysqldump file using ant sql task's src
Date Wed, 25 Oct 2006 02:49:55 GMT
While pouring through the source,I found a solution!

Heres a basic way to read most mysql dumps using the sql task's src: whether
it be triggers,storedprocs,fields that contain comments...

-put all triggers and stored procedures in their own file. and use the
task's delimiter attribute (requires you delete the DELIMTER statement,
which means 1 delim per file)

-for files that barf because the comment sequence is within a string eg
insert into properties (value) values("<!-- -->");
use the keepformat attribute. Although the description in the docs isnt so
good, i got the idea from looking at the code of  SQLExec.java

This should be good. The problem is that the <sql> task does a lot of
parsing on the sql before it sends it off to the database specific
connections.
