SQL string formatter [closed]

Answer 1

fsqlf (http://sourceforge.net/projects/fsqlf/) is a command line or GUI program, open source, to format SQL. It supports having a formatting.conf file which allows you a lot of flexibility in how the final product looks.

Examples:

☺  [wwalker@speedy:~] 
$ echo "select f1, f2, fname, lName from tblName where f1 = true and fname is not null order by lName asc" | fsqlf 

SELECT
  f1
, f2
, fname
, lName
FROM tblName
WHERE f1=true
AND fname is not null
ORDER BY lName asc
☺  [wwalker@speedy:~] 
$ vim formatting.conf # 2 character change
☺  [wwalker@speedy:~] 
$ echo "select f1, f2, fname, lName from tblName where f1 = true and fname is not null order by lName asc" | fsqlf 

SELECT
 f1 ,
 f2 ,
 fname ,
 lName
FROM tblName
WHERE f1=true
AND fname is not null
ORDER BY lName asc
☺  [wwalker@speedy:~] 
$ vim formatting.conf # 1 character change
☺  [wwalker@speedy:~] 
$ echo "select f1, f2, fname, lName from tblName where f1 = true and fname is not null order by lName asc" | fsqlf 

SELECT
 f1 , f2 , fname , lName
FROM tblName
WHERE f1=true
AND fname is not null
ORDER BY lName asc

Check out sqlparse. It is a Python module that installs the command sqlformat. Usage is simple, e.g.:

sqlformat --reindent --keywords upper --identifiers lower my_file.sql

I tried the aforementioned CLI alternatives, but:

• sqlinform is out, because I want an open source CLI application.
• fsqlf has only few features (create view is missing for example).

Thanks to sqlformat I even learned that "REF" is a reserved keyword in SQL:2011 and SQL:2008.
