[sqlite] Does anybody can port sqlite3-3.3.7 to uClinux based-ARModulator?
Hi guys uClinux version with 2003. kernel with linux-2.4.x. sqlite with 3.3.7 verdor with GDB. productor with ARModulator. compilied process work out as well.

Re: [sqlite] does sqlite support mutil-thread be run in samedatabase?
But I still get orignal error message, a pice of code as follow, suppose all
routines open the same database:
void fillSchedule(void *param)
{
Open();
...
Close();
}
void fillCredits(void *param)
{
Open();
...
Close();
}
int main(void)
{
Open()
...
Close();
hThreadSchedule = CreateThread(..., fillSchedule, ...);
hThreadCredits = CreateThread(..., fillCredits, ...);
WaitForSingleObject(.., hThreadSchedule,...);
WaitForSingleObject(.., hThreadCredits,...);
}
So does the through is right?

Re: [sqlite] does sqlite support mutil-thread be run in same database?
The next question is that if I want to use multi-thread in sqlite, so I need to open same database for two times, right? - Original Message - From: "LuYanJun" <[EMAIL PROTECTED]> To: "sqlite-users sqlite.org" Sent: Friday, January 19, 2007 10:53 AM Subject: [sqlite] does sqlite support mutil-thread be run in same database? > Hi guys > does sqlite support mutil-thread be run in same database? because of I am > stuck in such below sqlite error message: > error number = 21 > error message = library routine called out of sequence > certainly, I get some useful hints from stuff about interface of SQLite, but > I am not sure that weather sqlite support multi-thread. > Tks in advance.
[sqlite] SELECT * FROM Schdeule WHERE title LIKE '%%%'
Hi guy Suppose there is table name Schedule and more than two records be stored. however, one filed name as title and its values contain '%' in one of both records , so then such SQL pharse: SELECT * FROM Schedule WHERE title LIKE '%%%' be given , then return both records NOT only one . example: .. | .. | title| ... .. | .. | I hate you % | ... .. | .. | I love you | ... so what's problem come with me?
Re: [sqlite] SQL error: near "READ_ONLY": syntax error
Thanks, But I step the instruction fellow the hint by offcial document by which said that's correct(BTW forgive me my poor english ): http://www.sqlite.org/concurrency.html 4.1 Read-only transactions BEGIN READ_ONLY; SELECT * FROM t1; SELECT * FROM t2; COMMIT; 4.2 Defer write locks BEGIN READ_INITIALLY; SELECT * FROM t1; SELECT * FROM t2; COMMIT; 4.4 Defer writes BEGIN DEFER_WRITES; SELECT * FROM t1; -- Processing delay UPDATE t1 SET ...

Ok, Let me do it with C language
const unsigned char* Format(const char* szFormat, ...);
int AudioFillDatabase(const char* audiofile);
int main(void)
{
Open();
execDML(" CREATE TABLE IF NOT EXISTS AudioTable (id INTEGER , \n"
" name VARCHAR , \n"
" data BLOB , \n"
" type VARCHAR);");
AudoFillDatabase(SomeSongname.xxx);
Close();
exit(0);
}
int AudioFillDatabase(const char* audiofile)
{
FILE* fp = fopen(audiofile, "rb");
if ( fp == NULL )
return -1;
else {
fseek(fp, 0, SEEK_END);
long filesize = ftell(fp);
unsigned char* MemFileSize = new unsigned char[filesize + 1];
size_t ret = fread(MemFileSize, filesize, 1, fp);
if ( ret != 0 )
return -1;
else {
unsigned char* buf = new unsigned char[filesize+1024];
buf = Format("insert into AudioTable values (0, 'music', %Q, 'mp3');",
MemFileSize);
execDML(buf);
}
}
const char* format(const char* szFromat, ...)
{
va_list va;
va_start(va, szFormat);
static char* mpBuf = sqlite3_vmprintf(szFormat, va);
va_end(va);

[sqlite] Fw: Why can't I delete tmp.db after close sqlite?
