[sqlite] pragma quick_check, how do I use it in C?
Hi,
I can't get the quick_check instruction to work but I'm sure that I
must be doing something really stupid. It seems like my callback
function isn't invoked. I have this (just for testing) struct which
should be initialised properly when the callback is invoked, but the
values are always unchanged after sqlite3_exec(). Take for instance
the struct sq member argc. That struct member is always -1 after
sqlite3_exec().
Could someone help me and point out what I'm doing wrong here? I'm
using SQlite3 3.4.0. My code is below.
Thanks a lot,
jules
struct sq {
int argc;
char *argv;
};
static int
check_callback(void *hook,
int argc,
char **argv,
char **azColName)
{
struct sq *data = (struct sq*)hook;
data-argc = argc;
data-argv = (NULL != argv[0]) ? strdup(argv[0]) : NULL;
return 0;
}
static int
quick_check(sqlite3 *db)
{
int rc;
struct sq db_ok;
db_ok.argc = -1;
db_ok.argv = NULL;
rc = sqlite3_exec(db, pragma quick_check;, check_callback,
(void*)db_ok, NULL);
printf(%s(%d) - argc = %d, __FILE__, __LINE__, db_ok.argc);
if (db_ok.argv)
printf(%s(%d) - argv[0] = %s, __FILE__, __LINE__, db_ok.argv);

[sqlite] Strict affinity again
Hi everyone, I'm new to sqlite and this mailing list and hope to get some help here. I've used SQLite for some projects now and I must say, that it is the fastes database I ever used. Great work! But there is one thing, that I really dislike, because I get errors sometimes with this and that is the type guessing or the untyped way sqlite returns the data. So I searched the web and found http://www.sqlite.org/datatype3.html where strict affinity is described. I thought great, but how do I enable this option. After some search I found the thread from Feb. 2008. It sounds like that isn't a big code change and Samuel Neff wrote exactly that what I think about this : But the important point is that no matter how much discussion we have, we will never all agree that untyped is better than typed or that typed is better than typed. That's why an option so individual developers can choose is good. We don't have to agree, with an option we can agree to disagree. Sam So now my question: Why is this not implemented?

I'd really like this option!! Let me just say (again) that SQLite is not untyped. It is dynamically typed. Big difference. SQLite is strongly typed, it just does not place arbitrary constraints on what types of data that can be stored in a particular column. SQLite keeps the type information with the data itself, not on the data's container. If you want to place a restriction on a column such that it will only hold an integer (for example) you can use a CHECK constraint. CREATE TABLE example1(x INTEGER CHECK( typeof(x)='integer' )); D.

[sqlite] Insert performance in 3.6.11 vs. 3.5.5
Hi there, I have just upgraded SQLite in our application from 3.5.5 to 3.6.11 (we are using the amalgamation), and I have noticed a sharp drop in insert performance to more than half the speed that we had with 3.5.5. We are using SQLite in an embedded Linux device, and the database files are on a CompactFlash device. The inserts are being done into an initially empty table with 28 columns, and all inserts (can be more than 10) are done within one large transaction, using a prepared insert statement. One additional unique index on a single column is used on the table as well. With 3.5.5, inserting 1000 rows into that table took about 7 seconds, with 3.6.11 it takes 14-16 seconds. We are using PRAGMA synchronous = OFF and a cache size of 6000 pages. The main reason why we updated was because we experienced memory issues with 3.5.5. Reducing the cache size (PRAGMA cache_size) would not release memory. Any ideas what causes this? Apart from that we are very happy with sqlite. A big thank you to D. Richard Hipp and everyone who contributed to this great peace of software.

[sqlite] sql select of varchar text with special chars
Hello all,
I've a table in oracle that contains fields of type varchar2. In these fields
are TCL scripts that contain backslash chars and brackets.
Now, I've generated an SQL file from the Oracle table data that contains SQL
insert statements. I then use sqlite .read to read in the entire db. This runs
fine with no issues.
However, when I select the rows using SQLite (TCL api), I notice some of the
data comes back garbled and messed up. This doesn't happen to all of the rows,
just some of them.
How do I get around this? It's not exactly clear why the SQLite TCL API is not
handling some of the data properly.
Note that when I do a select using the sqlite3 command API, I don't see any
problems.
Below is the insert corresponding to a row that comes back messed up. By messed
up, I mean that the data that comes back has a \ for every space in the
original field. But that is not what the original data contained.
Thanks for any help!!

[sqlite] Documentation on SQLite indirectBLOB?
The Open Source project BitPim uses SQLite. I'm trying to examine the database BitPim creates.

I ran: sqlite3 bitpim.db then typed: .dump and saved the output to see what's in the database. The result is a set of SQL queries that can be used to recreate the database. In the output I found numerous references to columns of type indirectBLOB. When I look at the data that gets inserted into those columns, it's pretty clear that the value in those columns is of the form: /tableName/,/recordId/,/recordId/,...

Sqlite allows one to use most anything as a type -- BlobThatAteNewYork would work quite nicely. From sqlite's point-of-view, if a BLOB contains structure, it's structure known only to the calling application. Hope this helps, Donald -Original Message- From: sqlite-users-boun...@sqlite.org [mailto:sqlite-users-boun...@sqlite.org] On Behalf Of MBR Sent: Wednesday, March 25, 2009 6:09 PM To: sqlite-users@sqlite.org Subject: [sqlite] Documentation on SQLite indirectBLOB? The Open Source project BitPim uses SQLite. I'm trying to examine the database BitPim creates. At http://www.sqlite.org/download.html I found sqlite-3_6_11.zip, which is a pre-compiled Windows command-line SQL interface. I ran: sqlite3 bitpim.db then typed: .dump and saved the output to see what's in the database. The result is a set of SQL queries that can be used to recreate the database. In the output I found numerous references to columns of type indirectBLOB. When I look at the data that gets inserted into those columns, it's pretty clear that the value in those columns is of the form: /tableName/,/recordId/,/recordId/,... But I've been unable to find documentation on the keyword 'indirect' or 'indirectBLOB' anywhere on the web, including http://www.sqlite.org/docs.html. Can anyone here tell me where to find that documentation?

There will be no magic unless you also link a previously compiled sqlite library, or also include the sqlite3.c almagamation source code file in your project. Using Xcode. The model itself has about 30 or 40 different .c files and about a dozen or so .h files.

The rationale is at http://bitpim.svn.sourceforge.net/viewvc/bitpim/trunk/bitpim/dev-doc/database.html In the output I found numerous references to columns of type indirectBLOB. Generally the indirect is because the value is stored in another table. The BLOB bit is so that SQLite doesn't attempt to make any affinity conversions (it generally prefers to mangle things into integers which is fatal for phone numbers) . This is only deep and meaningful to BitPim itself. It has import and export functionality if you want the actual data. The SQLite database is structured so that Python dictionaries are can be used in the rest of the code. Each entry has arbitrary fields each of which can have any number of ordered values. Any entry can be looked up for any point in the past.

The model itself has about 30 or 40 different .c files and about a dozen or so .h files. I am a C newbie (but, by golly, I will learn some by the end of this), so be gentle in your replies. Grab the amalgamation, add sqlite3.c to your makefile and include sqlite3.h in your program files as necessary. At some point, you may want or need to add some compilation options depending upon your system (e.g. thread safety or page size). I usually create a wrapper for the database access so I can have some abstraction which makes sense for the objects I am working with and isolate all the SQL into one area of the code. What this wrapper looks like will largely depend upon your system and how you use SQLite. If you program in C++, you could consider a C++ wrapper to make your life even simpler. SQLiteDatabase.cpp from WebKit can provide a good starting point or be used as inspiration to roll your own. ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
