sqlite is not working.
i am tried hard to connect sqlite database using php. after lot of search, i found to include the below lines in php.ini. i am not sure where to include.
extension=php_pdo.dll
extension=php_sqlite.dll
i could't find even a word called sqlite in php.ini. can any give the sample php.ini with sqlite enable
If your connect to sqlite from pdo try (maybe) set in php.ini odbc.allow_persistent = On
When i install centos 5 to my server and check all repositories i don't find php-sqlite module and developers compile php without sqlite. I use PDO php function for sqlite:
$x = new PDO("sqlite:......");
And i thing your can try odbc.allow_persistent = On

Im trying to migrate a Gupta DB to MySQL. I already have a script to create every Table (with indexes and comments) and views I need in MySQL (table-, view- and column-names as well as column-types are equal in gupta as well as MySQL). But now I cant figure out how to read data from the old SQLBase Database and "import it" into the new MySQL database.
i thought of reading the old data from SQLBase and writing it in a file to then read it somehow via MySQL to import it. the Problem here is that for some tables there are more than 1 million records which i can not lose a single one of....
You can ETL natively from Gupta 'SQLBase' very easily. But you need to read the manual appropriate for your SQLBase version here: Gupta SQLBase manuals ( all verions ) , specifically, you need to read the 'UNLOAD' command in the 'Language Reference' manual. But best advice is: Don't do it ! Upgrade to SQLBase v12.2 instead.
HI we are using Adminer 4.3.1.
We choose system sqlite3 + localhost + location to DB file.
The error is not clear. I understood SQlite is supported. And I am directed to hardcoding functions to login. Don't I just need to use the form?
In short: how does one connect to a SQlite3 file using Admin?
Helpt appreciated ;)
I have the same issue, it does look like SQLite is broken in 4.3.1 because it is fixed in 4.3.2-dev, interestingly the login form has fewer options when SQLite is selected.
You can get the latest version by cloning the github repo and running adminer/sqlite.php
I have a huge problem... I am developing desktop app with SQLite but during copy/paste process I lost a power and process was terminated so base was lost. However, I found a way to recover it but base is encrypted. When I try to open connection using conn.Open(); I get this error. If I try to open it with DB Browser for SQLite it asks me a SQLCipher encryption password so it seams to me that data is lost..
Is there any default password ?
Why did this happen and how to prevent it from happening again ?
What can I do ?
Thanks in advance.
Also check that SQLite version you're "connecting" with aligns with the DB file version.
For example, here's a DB file written by SQLite version 3+:
$ file foobar.db
foobar.db: SQLite 3.x database, last written using SQLite version 3027002
And here I also have 2 versions of sqlite:
$ sqlite -version
2.8.17
$ sqlite3 -version
3.27.2 2019-02-25 16:06:06 bd49a8271d650fa89e446b42e513b595a717b9212c91dd384aab871fc1d0alt1
Obviously in hindsight, opening foobar.db with sqlite version 2 will fail, yielding the same error message:
$ sqlite foobar.db
Unable to open database "foobar.db": file is encrypted or is not a database
But all is good with the correct version:
$ sqlite3 foobar.db
SQLite version 3.27.2 2019-02-25 16:06:06
Enter ".help" for usage hints.
sqlite>
sqlite> .databases
main: /tmp/foobar.db
sqlite>
The error message is a catch-all, simply meaning that the file format was not recognized.
Ok, finally found a solution that works so posting the answer if anybody will have same trouble as I did..
First of all, use good recover software. For repairing the database I found 3 solutions that work without backup :
Open corrupted database using DB Browser an Export Database to SQL. Name it however you want. Then, create new database and import database from SQL.
There is software that repairs corrupted databases. Download one and use it to repair the database.
Download "sqlite3" from sqlite.org and in command line navigate to folder where "sqlite3" is unzipped. Then try to dump the entire database with .dump, and use those commands to create a new database:
sqlite3 corrupt_table_name.sqlite ".dump" | sqlite3 new.sqlite
I had the same error when I was trying to access a db dump in another system compared to compared to where it was obtained. When I tried to open on a dev machine, it threw the reported error in this thread:
$ sqlite3 db_dump.sqlite .tables
Error: file is encrypted or is not a database
This turned out to be due to the differences in the sqlite version between those systems. This dev system version was 3.6.20.
The version on the production system was 3.8.9. Once I had the sqlite3 upgraded to same version, I was able to access all its data. I am just showing below the tables are displayed as expected:
# sqlite3 -version
3.8.9
# sqlite3 db_dump.sqlite .tables
capture diskio transport
consumer filters processes
This error is rather misleading to begin with, though.
If you've interacted with the database at some point while specifying journal_mode = WAL, and then later try to use the database from a client that does not support WAL (< v3.7.0), this error can also come up.
As noted in the SQLite documentation under Backwards Compatibility, to resolve that without having to recreate the database, explicitly set the journal mode to DELETE:
PRAGMA journal_mode=DELETE;
Your database did not become encrypted (this is only one of the two options in the error message).
Your data recovery tool did not recover the correct data; what you have in the file is something else.
You have to restore the database file from the backup.
The issue is with sqlcipher version upgrade in my case, Whenever I update my pod it automatically upgrade the sqlcipher and the error occurred.
For a quick fix just manually add the SDK instead of Pod install. And for a proper solution use this link GitHub Solution
I have an application in C# that uses System.Data.SQLite. In my case I use a recent version of SQL Lite database, by now I can see that the new versión has released, and int sqlite.org webpage says that is recommended to upgrade the database.
My question is how to upgrade without lost the information in my actual database.
How can I chech the version of the data
Thanks.
EDIT: what I mean is when I create a new database with the sqlite3 library, I guess that the database file, my database.db has a version. When I update the sqlite3 library, I am update the sqlite3 command line, but the database file still has the version that had when I created it.
So if in the new versions for example add new features to the database, for example triggers, foreign keys and so on, if I am not wrong, this features must be in the database file, not in the sqlite3 library, because when I access to the database for example with entity framework, I don't use sqlite3 library, I use System.SQLite.Data library.
am I wrong? the datafile is never update and only the library can be updated?
Thanks.
Upgrading the SQLite library will not have any effect on your database file.
Changes like foreign keys do not affect the database file.
The last change that affected the file format was a long time ago.
how to install pdo sqlite drivers to enable onserver support
Assuming I understand the question, you want to know how to enable PDO SQLite access. Depending on the version of your PHP configuration, you may need to select different options, but assuming PHP 5.3.x, you should edit the php.ini to include the following libraries (for Windows - similar libs with different extension on *nix) in the extension=lib.dll (or extension=lib.so):
php_pdo.dll
php_pdo_sqlite.dll
php_sqlite.dll
This assumes they are available on your server and you can edit the PHP.ini config. If you cannot then you may have to ask your host provider to do this for you (which they may...).
SQLite Functions (PDO_SQLITE)
Introduction
PDO_SQLITE is a driver that implements the PHP Data Objects (PDO) interface to enable access to SQLite 3 databases.
