Re: [sqlite] BCD representation of floats
We actually added this type of capability to Sqlite (actually fixed point display format numbers), but it may be unnecessary in your case. Instead of representing integers as BCD how about using the 64 bit Sqlite integers? You may have sufficient precision. The COBOL-style COMP3 integers are pretty much obsolete these days.

Re: [sqlite] resetting a column back to its default value
Hello Puneet,
I guess I can select and reinsert all columns except for the column with
the default value.
I guess it would be nice (efficient) to update a single column to its
default value via the update command.

Imho the shell should rather implement the ! command to ask the bash (or other shell) to execute a command in its preferred format.

Re: [sqlite] BCD representation of floats
Liam, I know a great deal about oracle internals, Oracle stores "numbers" as you indicate in a bcd format. But It can be up to 22 bytes long. But usage in oracle proc/proc++/sql/plsql is really dependent upon your native conversion to host datatype. The number storage formats betweend Sqlite and Oracle are totally different. I don't think there is much your going to be able to do since the storage is different, most likely the precision is also going to be different and hence the outputs. Maybe you could implement a deviation check in your sqlite code. If the number produced fromsqlite matches oracle within a range +/- some number. Then it is considered equal. Also as your article implies you could modify the oracle data type to be a binary_float or binary_double which would store the value in a "native" ieee format instead of the NUMBER (which is more accurate). Another thought: Role your own NUMBER data type !!! Create a function inside sqlite that would basically implement an oracle Number representation. This should then produce exact match to oracle (in theory). You could use a text field or blob field to store the number datatype. Then apply your conversion function to it!

[sqlite] BCD representation of floats
I am porting a numerical application from Oracle to SQLite. For the most part, I have been successful, but there are slight disagreements in the floating point number results. I have traced this back and found a problem. According to http://articles.techrepublic.com.com/5100-22_11-5224536.html, Oracle by default stores floats as binary-coded decimal (BCD), and not IEEE754 binary. SQLite on the other hand does http://www.sqlite.org/datatype3.html: "REAL. The value is a floating point value, stored as an 8-byte IEEE floating point number." For the results of the application, it makes no difference how the numbers are stored -- the differences in the 15th significant figure are irrelevant. However, I would like to insure that there no disagreements in the way the two applications operate (other than the storage of floating point numbers), and for that I temporarily need exact agreement on input numbers. I cannot change the Oracle application, so I'm wondering if there's a wrapper or something I can put around sqlite calls (or better, a mode that I can put sqlite in) that will reproduce exactly the BCD format of Oracle. Thanks for any guidance. Liam ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
[sqlite] insert of string with line breaks
I've got an AIR app that does simple inserts into a SQLite db. The
insert looks like so:
var insStmt:SQLStatement = new SQLStatement();
insStmt.sqlConnection = dbconnection;
sql = "insert into hours(description,projectidfk,clientidfk,hours,date)
values(:description,:projectidfk,:clientidfk,:hours,:date)";
insStmt.parameters[":description"] = descriptionfield.text;
insStmt.parameters[":projectidfk"] = projectfield.selectedItem.id;
insStmt.parameters[":clientidfk"] = projectfield.selectedItem.clientid;
insStmt.parameters[":hours"] = hoursworkedfield.value;
insStmt.parameters[":date"] = dateworkedfield.selectedDate;
trace('desc is '+descriptionfield.text);
insStmt.text = sql;
insStmt.addEventListener(SQLEvent.RESULT, refreshHandler);
Notice I'm using bound parameters for all my values. The description
field is a text box. When I enter text with line breaks in it, the db
only gets line one of description.
Any ideas why? A string is a string even if it has line breaks in it -
afaik.

Re: [sqlite] Multithreads access the same database resultingin database is locked error
There can be only one thread that has an exclusive write lock on the database.
Most likely this is a bug in your application.
Heres what I do for my multi threaded app:
1. All transactions use "begin immediate" (that way I don't do a bunch of
work only to find the db locked later).
2. The begin immediate is wrapped in a while loop,
do {
begin immediate
} while (sqlite busy || sqlite locked).
3. Commit the transaction.
4. Select statements else where can also get sqlite_busy. This happens due
to the exclusive lock above! Its just the way sqlite works.
So, select statements the first step command can get a sqlite busy. S
prepare
refetch:
step
if sqlite busy
sleep a while
goto refetch
do {
work
step
} while (sqlite_row)

database is locked it stays locked and I cant update the databases with other

We don't; wherever did you get this idea from?

The first case is slower, since it has to make an extra sqlite3_mprintf
call (that achieves precisely nothing).

sprintf requires you to provide an output buffer (but not its length,
risking a buffer overrun). sqlite3_mprintf allocates its buffer (of an
appropriate size) on the heap (which you have to free afterwards). Also,
sqlite3_mprintf supports an extra format specifier - %m if I remember
correctly - which takes a string and turns it into correctly escaped SQL
string literal. This helps protect against SQL injection attacks (but
using a parameterized prepared statement is still better).

You don't need sprintf here either.

[sqlite] sqlite3_mprintf and Prepare
Hi,
I want to know why we have to use sqlite3_mprintf before sqlite3_prepare()
Case 1:
Query = sqlite3_mprintf ("DELETE FROM MUSIC WHERE URL = ?;");
sqlite3_prepare(db, Query ,-1,&stmt,0);
sqlite3_free(Query);
case 2:
We can also use directly - sqlite3_prepare(db, "DELETE FROM MUSIC WHERE URL
= ?;",-1,&stmt,0);
Will there be any performance difference between case 1 and case2.Kindly
help me to solve.Right now I am directly passing the Sqlite staments inside
sqlite3_prepare().Do I need to use sqlite3_mprintf or not needed.
Sometimes I am using sprintf instead of sqlite3_mprintf.will both have the
same functionality.After calling sqlite3_mprintf()we are freeing using
sqlite3_free but not sprintf().
sprintf(buff,"DELETE FROM MUSIC WHERE URL = ?;");
sqlite3_prepare(db, buff,-1,&stmt,0);
Thanks & Regards,
Mahalakshmi
