Data in field with datatype of TINYINT is returned as string

Anonymous — Thu, 12 Jan 2006 19:54:36 -0000

DB: MySQL Ver 14.7 Distrib 4.1.15
Ruby: 1.8.2

When I select data from a field with a datatype of
TINYINT, it is returned as a string, not an integer.

stHandle = @dbHandle.execute("select chk from table1
where id = 1")
rows = stHandle.fetch_all
row = rows[0]
row["chk"].class

This returns String

If I then change the data type in the database to
INTEGER, that code will return FIXNUM.

windows chmod glitch

Anonymous — Mon, 25 Apr 2005 23:36:56 -0000

attempted to install on windows. seems to be glitch
on line 655 of setup.rb (in rmf call). after the chmod, the
windows file is read only and then the file.unlink call for
file sqlsh.rb fails. probably a glitch with ruby windows
chmod call. changed the chmod to mode 666 & then it
worked ok in windows.

Can't have multiple processes accessing sqlite db files

Anonymous — Wed, 02 Feb 2005 14:31:47 -0000

Multiple readers/one writer is supported by sqlite.
This works (i.e. I tested it) with the perl DBI driver.
However it does NOT work with the ruby DBI driver. Is
there a work around?

PG type map hard to extended

Peter Williams — Thu, 07 Oct 2004 16:44:02 -0000

In dbd_pg, not sure about other dbds, there is no easy
way to extend the type map to support non-standard data
types such as those provided by PostGIS. Currently the
only way, I have found, is to override
DBI::DBD::PG::Database#load_type_map with something
similar to the standard implementation that includes
the new types. This is sub-optimal becuase it would
prevent multiple extension from being used at the same
time and it is prone to breakage on new releases of
this dbd.

column aliases do not work with SQLite

Andreas Schwarz — Sun, 11 Apr 2004 14:45:56 -0000

require 'dbi'
dbc = DBI.connect('DBI:SQLite:/tmp/test.db')
res = dbc.execute("SELECT column AS alias FROM table")
puts res.fetch_hash.inspect

Output:
{nil=>"1"}

sqlite-ruby alone doesn't have this problem.

Problem finding Oracle driver in 1.8.1

Daniel Berger — Fri, 27 Feb 2004 15:03:22 -0000

Ruby 1.8.1
Solaris 9
Oracle driver 0.2.11
ruby-dbi 0.21

Using "dbi:Oracle:my_db" as the connect string, I get
this with DBI:

>ruby dbitest.rb
/opt/lib/ruby/site_ruby/1.8/dbi/dbi.rb:490:in
`load_driver': is not a class/module (TypeError)
from
/opt/lib/ruby/site_ruby/1.8/dbi/dbi.rb:392:in
`_get_full_driver'
from
/opt/lib/ruby/site_ruby/1.8/dbi/dbi.rb:372:in `connect'
from dbitest.rb:6

This doesn't happen with 1.6.8, so there's some sort of
parsing error going on.

I have also heard that this happens with mysql.

Dan

sqlsh.rb require Readline broken since ruby 1.8.0

Dierk Koenig — Sat, 27 Dec 2003 17:31:08 -0000

The interactive shell sqlsh.rb requires the the Readline
class from irb.
The class is not available any more in the latests
distributions of irb, cf. the ruby 1.8.0 versions.
(1.8.0-10 installer package for Windows)

The code tries to avoid some dependencies in one place:

begin
require "readline"
$use_readline = true
rescue LoadError
$use_readline = false
end

but fails to avoid the indirect dependency through irb

require "irb"
require "irb/completion"

$irb_completion = Readline.completion_proc

A first workaround is

if $use_readline
require "irb/completion" # even irb is not clean in itself
$irb_completion = Readline.completion_proc
end

But things get a little bit messy then ...

Congratulation to your excellent work!

"SELECT field/n FROM table" is broken in 0.0.20

Anonymous — Sat, 14 Jun 2003 12:14:15 -0000

Query like this:
"SELECT cost/2 FROM pricelist"
gives error. In native MySQL it works.
