Re: multiple -f support

Hi all, I took a stab at changing this up a little bit. I pushed the logic that David introduced down into process_file(). In doing so I changed up the declaration of process_file() to accept an additional parameter specifying how many files are being passed to the function. Doing it this way also makes use of the logic for the current single transaction flag without turning it into dead code. I also added a check to return EXIT_FAILURE if any error was thrown from any of the sql files used, thus stopping execution of any further file. Gabrielle tells me the error echoed in this event is not clear so there is still a little more work that needs to be done. Regards, Mark

I assume having psql support multiple -f files is not a high priority or something we don't want. --------------------------------------------------------------------------- Mark Wong wrote: > Hi all, > > I took a stab at changing this up a little bit.

IIRC, nobody objected to the basic concept, and it seems useful. I thought we were pretty close to committing something along those lines at one point, actually. I don't remember exactly where the wheels came off. Maybe a TODO? -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

As Andrew pointed out, IIRC, you can do this with a little shell programming already. -- Simon Riggs http://www.2ndQuadrant.com/books/ PostgreSQL Development, 24x7 Support, Training and Services

I haven't looked at it in quite some time, though; there had been some concerns about how it worked in single-transaction mode and some other issues I don't recall off the top of my head. On this topic, I was thinking that it may be useful to provide an alternate multi-file syntax, a la git, with any argument following '--' in the argument list being interpreted as a file to process; i.e.,: $ psql -U user [option] database -- file1.sql file2.sql file3.sql This would allow things like shell expansion to work as expected: $ ls 01-schema.sql 02-data1.sql 03-fixups.sql $ psql database -- *.sql etc. Regards, David -- David Christensen End Point Corporation david@endpoint.com
