Thank you so much again. No, because after the fork both the parent and the child have the database open. There is a lot more to a SQLite database than just a file handle (like various operating system locks and other data structures). Basically you have to sqlite3_close all databases before doing a fork (don't forget to check the result is SQLITE_OK). If you are going to immediately do an exec then you should be ok - all files/directories are opened with FD_CLOEXEC. Even if SQLite did allow forking with open databases, it would need to be notified in some way before the fork so it could prepare. Pretend the notification function is sqlite3_close :-) Also a common fear seems to be using sqlite3_open multiple times. Unless you are in a seriously constrained embedded environment there is no harm in having lots of database connections even if they are to the same file.

[sqlite] process blocks on sqlite3_close?
Hi everyone!
I have a program that would create a child process. The run-through of the
part of the program is as follows:
[code]
int main()
{
pid_t pid;
int status = -1;
static sqlite3 *dbPtr;
status = sqlite3_open( "mine.db", dbPtr );
while(1)
{
if((pid = fork()) == 0)
{
printf("before closing parent db copy");
sqlite3_close(dbPtr);
dbPtr = NULL;
printf("after closing parent db copy");
status = sqlite3_open("mine.db", dbPtr);
if(status == SQLITE_OK)
{
// do some db queries here
sqlite3_close(dbPtr);
}
}
sleep(5);
}
return(0);
}
[/code]
Kindly take note of the sqlite3_close between the printings. I put it there
for the reason that when a new process is forked, it creates a new dbPtr as
a copy of the parent's dbPtr. I closed it then and opened so that the child
can have its own session of sqlite transactions.
However when I run the program for several hours, it would just print
"before closing parent db copy". And when i issue a ps command, there are
already 2 instances of the program running (1 parent and 1 child). And the
child is now running for an hour or so.
So if that is the case, maybe there is something in sqlite3_close that lets
the child process to halt. Im not sure though.
Any inputs will be greatly appreciated. Thank you so much!

Re: [sqlite] How to Modify Table
Sqlite does not support modifying the unique constraints on a table:
http://www.sqlite.org/lang_altertable.html
So you probably need to do it the 'ol fashioned way:
BEGIN;
CREATE TABLE Vehicles_new (
VehicleID INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
FK_CustomerID INTEGER NOT NULL,
VehicleNumber INTEGER NOT NULL,
VehicleTitle TEXT,
VehicleMake TEXT,
VehicleModel TEXT,
VehicleYear TEXT,
VehicleVIN TEXT,
VehicleDescription TEXT,
Active INTEGER DEFAULT 1 NOT NULL,
CreateDate DATE DEFAULT (date('now','localtime')) NOT NULL,
UNIQUE (FK_CustomerID, VehicleID));
INSERT INTO Vehicles_new
SELECT * FROM Vehicles;
DROP TABLE Vehicles;
ALTER TABLE Vehicles_new RENAME TO Vehicles;
COMMIT TRANSACTION;

Is there any way to make this change to the existing table without

[sqlite] ANN: SQLite Maestro 8.11 released (database encryption support and other features)
Hi! SQL Maestro Group announces the release of SQLite Maestro 8.11, a complete Windows GUI solution for SQLite database management. The new version is immediately available at http://www.sqlmaestro.com/products/sqlite/maestro/ What's new in this version === 1. Support for transparent database encryption has been implemented. It is possible to use SQLite Encryption Extension by Hwaci (if you have it) or a free wxSQLite3 library. 2. Remote database management has been significantly updated. Now you can connect to remote SQLite 3 databases as well as store the connection script in a password protected directory. 3. Starting with this version it is possible to use the lookup editor for a column, which is linked by a foreign key with a (single) column from another table. The editor displays the contents of parent table's columns within the dropdown window. 4. A possibility of displaying data in the master-detail form has been incorporated into the Table Editor (multiple detail pages can be displayed for a single master row). 5. Filtering, grouping, and sorting features become available for TEXT columns. 6. Data Import Wizard: now it is possible to truncate the table before importing. 7. Get SQL Dump Wizard and Extract Database Wizard have been redesigned to increase the usability. 8. Data Export, Data Import, and Get SQL Dump wizards now store their size and position. 9. Some other minor improvements and corrections. Full press release: http://www.sqlmaestro.com/news/company/5570/ Background information: SQL Maestro Group is engaged in developing complete database admin and management tools for MySQL, Oracle, MS SQL Server, PostgreSQL, SQLite, DB2, Firebird, SQL Anywhere and MaxDB providing the highest performance, scalability and reliability to meet the requirements of today's database applications.

[sqlite] Problems using AUTOINCREMENT row IDs in indexes
I'm having problems getting good index choice in SQLite 3.6.4 for a field which is INTEGER PRIMARY KEY AUTOINCREMENT. I've got the following table: CREATE TABLE Signals (sSignalID Text DEFAULT '',sText Text DEFAULT '',sTime Text DEFAULT '',sUserID Text DEFAULT '',nRowID INTEGER PRIMARY KEY AUTOINCREMENT DEFAULT '0'); with index: CREATE UNIQUE INDEX idxUserID ON Signals (sUserID, nRowID); In my test cases I've got around 2 million records in the table, with only 6 or so sUserID values. In practice there will be thousands of distinct sUserID values. This query: SELECT * FROM Signals WHERE sUserID='[EMAIL PROTECTED]' AND nRowID >= 1932308 and nRowID <= 1932508 takes 380 ms to execute. If I do this: ALTER TABLE Signals ADD COLUMN nRowID2 INTEGER UPDATE Signals SET nRowID2 = nRowID CREATE UNIQUE INDEX idxUserID2 ON Signals (sUserID, nRowID2); and run this: SELECT * FROM Signals WHERE sUserID='[EMAIL PROTECTED]' AND nRowID2 >= 1932308 and nRowID2 <= 1932508 it takes 1 ms. I get similar results for this sort of query - a dramatic speedup when using the clone field nRowID2: SELECT * FROM Signals WHERE sUserID='[EMAIL PROTECTED]' AND nRowID < 100 ORDER BY nRowID DESC LIMIT 100 Looking at the query plans it appears that the nRowID queries aren't exploiting the fact that nRowID is in the index idxUserID. That index is used, but there is no seek using the nRowID as well as the sUserID. Why should the fact that the nRowID field is INTEGER PRIMARY KEY AUTOINCREMENT prevent it from being used properly in query index selection? How can I get AUTOINCREMENT behaviour as well as good index selection? Is this an SQLite bug?

[sqlite] (no subject)
I am resending my transactions based on the result code that is returned. Should I put the time out command in my loops or once set does time out apply to each transaction despite the resends? And does the timeout command apply only to connecting to the data base or to each request? ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

In my program, I do an integrity check on many DB's before I use them. I consider a damaged DB to be a fatal error so, I rename and open a new one. Most of the data I store though isn't mission critical. I use SEH try catch blocks around the more dangerous code in my program. -- Best regards, Tegmailto:[EMAIL PROTECTED] ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

[sqlite] Query Sqlite lock state
Hello all, is there a way to query if the database file is currently locked ? Background: My application may run for weeks (hopefully) and uses EXCLUSIVE transactions in some threads. On a daily basis I would like to copy the database file for backup purpose. I assume that this will fail when there is an exclusive transaction ongoing. It would be more elegant to ask sqlite rather than test against a FileCopy failure. I found the "PRAGMA locking_mode" statement, is this the one to use ?
