Обсуждение: oracle to postgres migration question
Hello, I'm looking for the postgres equivalent of oracles: set numwidth command. Is there an equivalent? Thanks in advance! - Josh -- Joshua Gooding Software Engineer TTi Technologies Wheeling, WV 26003 w: 304-233-5680 x 308 c: 304-794-8341

Psql uses dynamic formatting for such things. Not sure there's really a big need for it. Can you give an example of what you're trying to accomplish? (and as Bruce mentioned, you'd get more bites if you gave a reference like http://www.oracle.com/technology/support/tech/sql_plus/htdocs/sub_var4.html#4_1_6 so people would know what you're asking for.)

Nothing really equivalent, I don't believe.. You would need to wrap
the column(s) you care about using to_char().
Thanks,

SQL*Plus will then right-justify the number based on the numwidth value. Stephen

Note that psql automagically right justifies numerics and dynamically sizes all columns so you don't have to do as much of this stuff. Oracle always made me feel like I was operating the machine behind the curtain in the Wizard of Oz, lots of handles and switches and knobs I had to mess with to get useful output.

People who are trying to parse psql's output directly should realize they probably are going about it the wrong way. :) Stephen

The problem I was having, is the data in field 'track_start' was a number type in oracle. I switched it out to a real in postgres, however when I displayed the column (via psql) it was printing out for example (1.23546e12). I know you could format the output via Sql Plus but I was not sure what (if anything) you could do in postgres for that. That being said, I then re-modified the field type and it displays properly. I went from a real to a integer type and it seemed to clear up every issue I was having (both displaying and programatically) -- Joshua Gooding Software Engineer TTi Technologies Wheeling, WV 26003 w: 304-233-5680 x 308 c: 304-794-8341

If you're at least making the output something like tab, space, pipe delimited you can parse it. On systems with only bash to play with, I've done that before because it and psql were the only tools I had to work with. I wouldn't try to write some masterpiece artwork of code around psql output, but for some short scripts it's usable, and way easier than dealing with Oracle.
