[sqlite] [shell] utf-8 bug

[Jens Frederich]

Hi all,

I believe there is a bug in shell tool on Windows. I've tried to store
utf-8 encoded literals in my test db. Do the following to reproduce the
issue:

1. Open a Windows Console (cmd.exe)
2. chcp 65001  # change cmd.exe code page from 437(OEM) to utf-8
3. Run the shell
   > sqlite3.exe test.db
   > create table test(id integer primary key, value text);
   > insert into test (id, value) values (1, 'füchsen'); # literial with
multi byte characters

The shell unexpectantly closed on the last command.

What is the preferred way to save utf-8 encoded literals with the windows
shell tool?

  Jens

[sqlite] search

[Durga D]

HI all,

   I have sqlite database with more than 1000 records. Here,
residencearea is the primary key.

   for ex:

/country/state/city/village
/country/city
/country/state/city
/country/

country: USA, UK, CHINA


   Here I want to search based on country and sometimes search based on
village and sometimes search based on /country/state/.

   I tried with fts3 and fts4 virtual tables. Not much performance.

   like query on direct table, dead slow.

   Any alternate solution for this?

Thanks in advance.

Regards,

REPLACE is an alias of INSERT OR REPLACE.
http://www.sqlite.org/lang_replace.html

The record is inserted, then duplicity is deleted. If you want to
update record, use the UPDATE.

Re: [sqlite] Bug in trigger: when comparing a value of an int column to a quoted value

[Alexey Pechnikov]

Of cource you may report your bug! But I'm not sure about possibility
of the bugfix in upstream and so I speak about patch to SQLite binding
for your language.
