Hi,
from my experience the query "PRAGMA case_sensitive_like;" doesn't return the
pragma's current value.
I suppose this is the intended behavior but I'd like a confirmation since I
can't find an answer in the docs.

Dear Pavel,
Finally, it seems that you were right: the person confirmed me that the
software was not running with a PC with the framework 4.0. It works fine
with another PC with framework 3.5.
My application is compiled with the framework 3.0.
Thus, could you please let me know what framework
Hello,
Let me start by saying using SQLite in Tcl is a real pleasure!
I am having a problem determining when to use $ and when to use @ (and maybe I
should use :, but I haven't tried it).
I have three tables: terrain(x,y), detail(id integer primary key autoincrement,
x, y), and units(id
Hi
I am using getErrorCode() of SQLException to see if the exception is due
to any database lock. I all the time get Errorcode to be 0 even though
the getMessage is returning different messages. Can anyone let me know
if there is some thing that i need to do to get the error codes correctly ?
Can anyone comment about whether the SEE is delivered as an amalgamation, or
whether it comes as pre-amalgamation files?
Thanks

Assume that a table has several check restraints, such as a unique index and
a foreign key.
When inserting a row that violates more than one of the constraints, is
there any way to tell which of the constraint would have
been violated?
Thanks,

SEE is a single file of C code that you append to a standard "sqlite3.c"

I have a database that returns SQLITE_CORRUPT during certain queries,
but other than that it opens, closes and generally works fine.
- Is there a way to check the database when its open, other than running
through a bunch of test queries?
- Is there any general way to fix corruption issues?

I believe there is, it would be highly interesting.
Please keep me and others posted, and let me and all others know the results
of the test/-s!

Sorry, I can't answer these questions. I'm not on SQLite
I have a table foo with N rows and I want to know the offset of the row with
rowid X inside that table.
What query/strategy should I perform?
I assume that a brute force algorithm should be
1. SELECT * FROM foo ORDER BY rowid;
2. loop inside the recordset until X is found incrementing a counter
Hi,
select count(*) from foo where rowid < X

Thanks Martin and Richard, solution was so simple that I think to need a time
break today.
Should I add an ORDER BY rowid clause at the end of the SELECT statement or its
implicit by the WHERE clause?
Thanks a lot.

No, an order by does not make any sense here, because the result set
contains exactly one row.

Hello Sridhar,
please tell us more: what interface are you using? what OS?
SQLException is not a part of the sqlite library, so obviously you use
an additional layer.

I am on windows 7 and this is my test code
try
{
Statement stat = mconn.createStatement();
stat.execute(sql);
resultSet = stat.getResultSet();
mconn.close();
break;
}
catch (SQLException e)

Any one with java/JDBC experience please have a look at the snippet and
let me know why I am not able to get the exact errorCode.

Hello,
This may seem a very simple issue it is giving me some very hard time.
I need to add a variable amount of months to a date.
According to the doc, this is done for adding 1 month :
SELECT date('now','+1 month');
And I would need something like SELECT date('now','+$i month');

Hi,
I find the PRAGMA table_info(*tablename)* command very helpful.
However, sometimes I want to extract table headers for a table constructed
by a query which does not have the exact same headers as any one table in my
database.
For example:
Table 1 headers: A, B, and C
Table 2 headers: a,

You can do like this:
SELECT date('now','+' || (SELECT id FROM table) || ' month');

I've only used the xerial driver recently and haven't checked for the
error code on exception. It does come with source, so you may be able
to walk into the code to see how the value is set/retrieved.

If you insist on getting results as resultset then there's no way to
do that. But you can do the similar thing by using API like
