Get this working with multi-line statements #5

Closed nathanielks closed 5 years ago

nathanielks commented 5 years ago

I discovered today that this won't be able to parse multi-line insert statements like the following SQL:

INSERT INTO `wp_cavalcade_jobs` VALUES
(1,1,"wp_version_check","a:0:{}","2017-08-24 08:15:12","2017-09-11 20:15:12",43200,"failed"),
(2,1,"wp_update_plugins","a:0:{}","2017-08-24 08:15:12","2017-09-11 20:15:12",43200,"failed"),
(3,1,"wp_update_themes","a:0:{}","2017-08-24 08:15:12","2017-09-11 20:15:12",43200,"failed"),
(4,1,"wp_scheduled_delete","a:0:{}","2017-10-15 10:11:15","2017-10-15 10:11:15",86400,"failed");

Because we're parsing line by line, it reads each value as its own SQL statement which breaks the parser. I need to either merge them all into a single line or find some other solution.

It might be possible to activate a flag saying "treat the following queries like they're an insert statement for table X until we receive a new query."

We could also store the initial INSERT INTO statement and then prepend it onto the following lines until a new query is received.

Another option with the flag option I presented before would be to look for a ; at the end of the line, which would signify that query is terminated.
