Re: [HACKERS] psql shows line number
2013/11/26 Sawada Masahiko sawada.m...@gmail.com Hi all, When I execute query which contains error, the server returns error with line number. ERROR: relation hoge does not exist LINE 35: hoge; But when query is long, I was not sure the location where I wrote wrong SQL. Does the psql have option which shows line number? If no, I'm thinking to implement this feature. Thought? I think it is useful if the psql shows line number like follows [1]postgres=# SELECT [2]postgres=# hoge.col1 [3]postgres=# FROM [4]postgres=# hoge; ERROR: column col1 does not exist LINE 2: col1 And If there is discussion at past about this, please let me know. idea is interesting, but a proposed format is not clean (and little bit ugly, and can be barrier for copy from terminal to editor. Now, simple replace can be used for cleaning. maybe we can introduce a command, that will print SQL from history with line numbers - like \sf+ regards Pavel Regards, --- Sawada Masahiko -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

So I thought that psql can also have such feature as standard function. idea is interesting, but a proposed format is not clean (and little bit ugly, and can be barrier for copy from terminal to editor.

I was also thinking to fill space of line number with whitespace. likes: [ 1]postgres=# SELECT [ 2]postgres=# hoge.col1 : [ 9]postgres=# FROM [ 10]postgres=# hoge; But I think that it is also something just isn't right. maybe we can introduce a command, that will print SQL from history with line numbers - like \sf+ I think that ¥sf+ shows definition of function. How should I use this?

I don't actually see the point of this. If you're working with queries that are long enough that counting lines is even slightly difficult, surely you're going to use \e to correct the problem? So it seems to me that the existing \e nnn facility pretty much does what's needed, and there's no great need to clutter your regular display with line numbers. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

I agree in the sense line numbers don't help. But \e is not really a solution to the problem. A pretty common thing for me to see (as an artifact of my styling) in the log: ERROR: syntax error at or near from LINE 223: from ^ Not very helpful. Also good luck if your SQL is dynamically generated. What I think would help *would* be able to optionally add a some lines of context: then you'd at least have a shot at eyeballing the error etc. merlin -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
