Re: [sqlite] VC++ and SQLite
I used Borland when I was a student too and a little bit after I graduated, I used OWL once, what a mistake, soon after Borland dropped the ball on OWL; left me stranded. Ever since I use GNU and GTKmm, they appear to be much more stable than Borland. Microsoft is stable, no doubt, but too complicated; just have a look at the madness of MFC or try to play a sound file using WIN API code. No man, I am not an advocate for anyone but me and what I find to be good. I am not loyal to companies or consortiums; I am loyal to me and what I find to be good to me. MS was never free before FSF pushed it to give a bit of its millions of $ back, after that, even MS-Windows started to feel like Linux. Linux proved to be just as good as, and some times better than MS. Linux developers didn't need the complexity of VS10 or a simple IDE like Code::Blocks to create or participate in the creation of an OS so much better than those using VS to develop theirs. MS-VS developers should spend more time creating more effective documentation and less time developing a new Language/Dialect for the IT industry.

Re: [sqlite] C++ - HOW MANY rows?
Look, Sir, I appreciate that you have spend your time and energy responding to my question, in fact, I have used your suggestion to have a look at the other guys' C++ wrappers of the SQLite3 library, but my intention is to learn SQL using the SQLite3 API. I am using C++ and not the 'prompt', because I will ultimately use C++ to implement my knowledge of SQL and SQLite3. Just so that we are clear, I don't mind trying and failing a thousand times, I need to know how this thing works! On the other hand, I really like your analogy of the book being opened, the pages being read and then closing the book again, it is brilliant concept. I see now that I need to reorganize my class so that I can have the 'finalizer' method called only once at the end of the database transaction. I hope, and I am counting on everyone here, to eventually release mySQLite3 in the public domain.

Arbol One arbol...@gmail.com wrote: Since the call to the sqlite3_step function is inside the mySQLite3::read_* class-function/method ... it is clear that you have a poor class design. As you would generally want to read several columns from the same row, it is unwise to have a read_* method call sqlite3_step, thus advancing to the next row. It is even less wise to have it call sqlite3_prepare and sqlite3_finalize. Now, in a while loop inside Runner::read_tblName() I could call the mySQLite3::read_* for the data to be retrieved, but instead of reading the next row of data, it keeps on reading the same row again and again. Because you prepare and finalize the stament again and again. Think about it this way: sqlite3_prepare call opens a book, sqlite3_step call turns a page, sqlite3_finalize call closes the book shut. Your read_* method opens the book, turns to the first page, reads one line, then closes the book. The next read_* call opens the book again, turns to the first page again, reads another line, and closes the book. Again, and again. Is it still surprising that you never progress past the first page? Obviously my problem is in design Indeed. but I don't have enough experience using SQLite3 to come up with a better idea. In this case, perhaps you should consider using, or at least studying, some existing libraries.

Try using this method...you just need to ensure mystmt is set to NULL to
start with and reset to NULL in finalize().
const int mySQLite3::read_int(int pos)
throw(somexception) {
if (mystmt == NULL) { // Ensure mystmt is set to NULL in constructor
rc = sqlite3_prepare_v2(db, SQLStatement.c_str(), -1, mystmt, NULL);
if(rc != SQLITE_OK) {
try {
this-display(rc, FILE, METHOD, LINE);
} catch(somexception e) {

}
}
rc = sqlite3_step(mystmt);
if(rc == SQLITE_ROW ) {
apint = sqlite3_column_int(mystmt,pos);
counter++;

if (rc != SQLITE_DONE) {

Thanks Igor for your prompt response.
Since the call to the sqlite3_step function is inside the mySQLite3::read_*
class-function/method, I call the read_* method from Runner::read_tblName()
for each datum I need to retrieve. Now, in a while loop inside
Runner::read_tblName() I could call the mySQLite3::read_* for the data to be
retrieved, but instead of reading the next row of data, it keeps on reading
the same row again and again. Furthermore, I have no way to let
Runner::read_tblName 'know' that there is no more data, hence stopping the
while loop.
Obviously my problem is in design, but I don't have enough experience using
SQLite3 to come up with a better idea.

well.. you already answered your question:
You step thru the result list until you reach SQLITE_DONE.
In your example you re prepare the statement all the time and thus you will
always get the first hit in your data.
The sequence should be:
sqlite3_prepare_v2
while( sqlite3_step(mystmt) == SQLITE_ROW ) {
/** read the data .. **/
}
sqlite3_finalize

The problem I have is that I have no control as to the exact location where
I want the data to be stored, look the table below to have a better idea of
what I mean.
My question is, is there a function that will allow me to directly plug the
data at that specific index I want?
Ultimately, what I want to do is to store all the data in ONE row. How is
this handle in SQLite3?
TIA

[sqlite] C++ - nothing has been stored!!??
And here I am again, asking for what you find so easy and I. well, just
cannot understand.
I am trying to write to a database table previously created by another
process like this:
void someClass::create_tblName() {
sql_param_tblName = CREATE TABLE name(n_id INTEGER PRIMARY KEY, title
TEXT, fname TEXT, mname TEXT, lname TEXT);
try {db-createTable(sql_param_tblName); } catch(someException e) {...}
}
void mySQLite3Class::createTable(const Glib::ustring s) throw
(someException) {
rc = sqlite3_prepare_v2( db, s.c_str(), -1, stmt, NULL);
if(rc != SQLITE_OK ) { throw someException }
rc = sqlite3_step(stmt);
if(rc != SQLITE_DONE) { throw someException }
}
}
The actual writing to the table looks like this:
void someClass::write2tblName() {
stmtName = INSERT INTO name (n_id, title, fname, mname, lname) VALUES
(?, ?, ?, ?, ?);
int data1 = 10;
int pos = 1;
try{db-write(stmtName,pos, data1);}catch(someException){.}
}
void mySQLite3Class::write(const Glib::ustring sql_stmt, int pos, int data
)throw(someException) {
rc = sqlite3_prepare_v2(db, sql_stmt.c_str(), -1, stmt, NULL);
if(rc != SQLITE_OK) { throw(someException)}
rc = sqlite3_bind_int(stmt, pos, data);
if(rc != SQLITE_OK) { throw(someException) }
}
but this does not store anything in the database table. I have used an
sqlite browser to determine if, in fact, some data was stored, but no,
nothing has been stored.
What am I doing wrong?

You were doing two sqlite3_step()'s instead of one. So you skipped the one

You can run this multiple times and you;; see error messages about the

[sqlite] C++ - ISERT from a data object
In my GUI application the user enters a information that will go in a SQLite
database table, so statements like:
string dbdata = INSERT INTO friend (name, address, age) VALUES ('Caramba',
'490 New Bridge', '49');
are not very useful in a real life C++ GUI application. I would assume that
SQLite has functions to submit information in the form of string object to
a table i.e.:
--snip--
std::string name;
int age;
sqlite3_submit_data_text(db, table, name, ..);
sqlite3_submit_data_int(db, table, age, ..);
What is the C++ API for entering data to a table?
Thanks!!

[sqlite] C++ programming - SELECT question

[sqlite] C++ programming - getting data from a table
in a database called 'db' I created a table named 'friend' that looks like
this:
string create_table( CREATE TABLE friend (name TEXT, address TEXT, age
INT));
I entered some values in that table and now I would like to extract the
values from that table. Shown below is what I have done so far, but I have
hit a wall, I cannot find definitive information as to how to view the
extracted data, if any.
What do I do next to view the data from that table?
TIA
snip
getData(){
string sName;
string sAddress;
int age = 0;
string dbdata = SELECT * FROM friend;
rc = sqlite3_prepare_v2(
db, /* Database handle */
dbdata.c_str() , /* SQL statement, UTF-8 encoded */
dbdata.length(), /* Maximum length of zSql in bytes. */
stmt,/* OUT: Statement handle */
NULL /* OUT: Pointer to unused portion of
zSql */
);
rc = sqlite3_step(stmt);
?

Shown below is what I have done so far, but I have hit a wall, I cannot find definitive information as to how to view the extracted data, if any. What do I do next to view the data from that table? [Simplified answer for SQLite starter] You're asking about the set of commands which go _prepare(), _step(), _finalize(). These are commands which create, use and destroy an SQLite statement. Do one _prepare() which causes SQLite to do complicated things to make a statement. Do _step() to get a row, and continue to do them while it continues to give a result code of SQLITE_ROW Do one _finalize() to tell SQLite you no longer need that statement's handle, memory, etc.. If _step() returns SQLITE_ROW it makes available one row of the resulting table. You can read the data from that row using functions like sqlite3_column_int() and sqlite3_column_text(). You need as many of these calls as you expect columns returned by your SELECT statement. You pass into that function the statement handle, and the number of the column you want, with column 0 being the first column. Details of the statement loop are here: http://www.sqlite.org/c3ref/stmt.html Details of how to retrieve the values of a row are here: http://www.sqlite.org/c3ref/column_blob.html Hope this helps.

sqlite_column_* functions are only meaningful for queries that produce a
resultset - namely, SELECT and certain PRAGMAs. None of the data definition
statements (of which CREATE TABLE is one), nor INSERT, UPDATE or DELETE
statements, produce a resultset; thus, sqlite3_column_* functions couldn't
be used with them.
What are you trying to achieve here? What's the supposed purpose of
sqlite3_column_type call?

Since there seems to be a confusion about the application I am using to view
the newly created table and the data entered to it, I asked the question you
are referring to in order to establish a common ground, an application to view
the data in which we can discus on.
If you have an idea of a freeware I could use as a test bench, I would really
appreciated if you let us know.

[sqlite] C++ programming - int sqlite3_open_v2() question
int sqlite3_open_v2(
const char *filename, /* Database filename (UTF-8) */
sqlite3 **ppDb, /* OUT: SQLite db handle */
int flags, /* Flags */
const char *zVfs /* Name of VFS module to use */
);
In my Windows 7 box, using MinGW I am trying to use sqlite in my c++ program,
but the parameters used in int sqlite3_open_v2() are not totally clear to me
and I hope you are able to help me.
Here is an example of what I would like to do,
void mydb(){
std::string db_name(test);
std::string my_name(Programmer);
int my_age = MAX_INT;
.
rc = sqlite3_open_v2(db_name.c_str(), *??1*, db, SQLITE_OPEN_READWRITE |
SQLITE_OPEN_CREATE, *??2*);
if(rc != SQLITE_OK){
std::cout error one std::endl;
exit(-1);
}
else{ std::cout it's working! It's working std::endl;}
sqlite3_close(db);
cout Good bye! endl;
return 0;
}
What do I input as *??1* and *??2* ? and do I need to grab ??1 to later use
it?
Thanks folks!
Please note, that I am trying to learn SQL as I learn how to apply this
knowledge in c++, what you see above is pretty much all my knowledge of SQL,
so, go easy on me, OK?

Re: [sqlite] C++ programming - int sqlite3_open_v2() question
Thanks Stephan for the help, with a little bit of reading and a lot of your
help, I have come to understand how opening a data base file in SQLite is done.
Here is a code I came up with:
void mydb(){
std::string db_name(test);
std::string my_name(Programmer);
int my_age = MAX_INT;
std::string vfs(win32);
.
rc = sqlite3_open_v2(dbName.c_str(), db, SQLITE_OPEN_READWRITE |
SQLITE_OPEN_CREATE, vfs.data());
if(rc != SQLITE_OK){
sqlite3_close(db_name);
std::cout naaa, you ain't got it yet... press any key and keep trying.
std::endl;
std::cin.get();
exit(-1);
} else {
std::cout Welcome to a whole new world! std::endl;
std::cin.get();
}
sqlite3_close(db_name);
cout Good bye! endl;
return 0;
}
Now, my next step is to create data tables, but that will be on another email.

Thanks for the info. Yes, I read that page, but since the purpose of this exercise is to acquire a good understanding of SQLite under C++, I decided not to use the *sqlite3_exec* wrapper, but to execute each and every step of the development process. I know is not the fastest way, it involves more code, but it is serving me very, very well. In the future, I will use the wrapper, but for now I find it that it is necessary that I understand the long and tedious way... yes, I know...

Now my step two looks like this

rc = sqlite3_prepare_v2(
db, /* Database handle */

);
if(rc != SQLITE_OK) {
sqlite3_close(db);
std::cout error prepare_v2 std::endl;

however, this gives me a run time error that reads
*#0 0x00446642 in ??() (??:??)*

story as with sqlite3_open_v2 and DB handle. You declare a variable like
sqlite3_stmt* stmt;, then pass stmt. ?? /* OUT: Pointer to unused portion

sqlite3_prepare_v2 only prepares the statement, but doesn't actually execute
it. To run the statement, you would call sqlite3_step. After you are done, call
sqlite3_finalize to free resources associated with the statement; and
sqlite3_close to close your database connection. -- Igor Tandetnik

At least it is so on the sqlite-users mail-list. 5. No need for e-mail-addresses to be exposed Couldn't a mailing list hide email addresses too? Perhaps it could.

On the other hand, I find mailing lists much better: I can read them off line, I can also answer them off line (my client will send my answers as soon as it gets online), I can archive any and/or all posts that I find valuable. I get messages from others when they are on their way to work or home sitting in trains and busses. Mostly people are just online through wireless or mobile networks. It is considered in to be able to access the Internet at all times in all places, so I find that point a bit moot nowadays. In fact, when fora (forums?) propose a mailing list interface (i.e. google groups), I prefer subscribing to them as a mailing list. Even better than mailing lists: newsgroups. Except my company only lets us use port 80 in addition to the mail gateway, so I can't use newsgroups. Who am I tell someone what to prefer. I just find, however, it is a bit religious like choice of OS or gadgets. I can see that e-mail lists can work and in the past could have a lot of advantages.
