Subject: PATCH: SQLite IF*EXISTS, comments in CREATE statements
Download (untitled) / with headers
text/plain 466b
This patch allows DROP TABLE IF EXISTS foo; CREATE TABLE IF NOT EXISTS foo (); and column specs that include trailing comments, like count INTEGER, -- number of stored items tstamp TIMESTAMP -- when the items were stored I also tried to make the parser skip over INSERT statements as my schemata often come with some preloaded static table contents. -- but failed. t60 is confused by my trailing comment removal code, I only fixed the symptoms there, sorry.

Please resubmit patch with an actual test - extend the table definitions in t/data/sqlite/* and then make sure t/27sqlite-parser.t parses them properly. Thanks!
