OT: Reply-Adress in this list
I use some mail-lists for mysql, php and security with Outlook Express. When I reply, some lists set their list-adress automatically, some the adress of the person originally posting. The second version may not so good IMHO, because I think so many replies are not going to the lists. mysql++ and mysql do not automatically reply to the list mysql-de does. I think the a big Problem with the first solution are some autoresponders which may spamming mainling lists. I'm not a freak in mailservers, but maybe others know if there's a better configuration. Maybe I can configure my Outlook Express better? -- [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: MySQL as a desktop DB
I think MySQL will be more faster in Desktop environment and if you are adverse to using the text based interface to MySQL then you can try out some GUI avaiable in the market. The best I know are MySQL-Front and SQLyog but since MySQL-Front has been discontinued you can try SQLyog at http://www.webyog.com/sqlyog Have you ever tried OpenOffice as a Frontend for our mySQL?

Re: Store pictures in DB
Can I use MySQL to store pictures as part of a record? You CAN. Should I just try to store the name of the picture? Yes. If you have FTP Access or similiar, I would prefere this! Some remarks from the manual : -- Insert a File located locally on MySQL-Serverinto a blob-column INSERT INTO media_binaerdaten (Daten) values(load_file(c:/tmp/test.zip); -- get length of blob-fields SELECT Key,length(Daten) FROM `media_binaerdaten` WHERE 1 SELECT Daten FROM `media_binaerdaten` WHERE FKMedia_ID=47 INTO OUTFILE C:/tmp/test.zip - get data WITH escapes, can be insertet again SELECT Daten FROM `media_binaerdaten` WHERE FKMedia_ID=47 INTO DUMPFILE C:/tmp/test.zip - get raw data (WITHout) escapes, can be used as binary, e.g. *.zip or *.exe Escaping --- If you want to insert binary data into a BLOB column, the following characters must be represented by escape sequences: NUL ASCII 0. You should represent this by `\0' (a backslash and an ASCII `0' character). \ ASCII 92, backslash. Represent this by `\\'. ' ASCII 39, single quote. Represent this by `\''. ASCII 34, double quote. Represent this by `\'. If you write C code, you can use the C API function mysql_escape_string () to escape characters for the INSERT statement. See section 22.3 C API function overview. In Perl, you can use the quote method of the DBI package to convert special characters to the proper escape sequences. See section 22.5.2 The DBI interface. You should use an escape function on any string that might contain any of the special characters listed above! greetings by a busted by blobs-coder ! -- [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: Store pictures in DB
+1 For medical imaging, at least in radiology (PACS), you usually see the terabytes of images being stored on a NAS somewhere, and the database itself is actually pretty small just pointing to filenames of where the pictures are located. This keeps the database small and fast, and lets you add storage without the complication of using Logical Volume Management since you don't need to extend your filesystem to add space. Just add a completely new block of space and start writing your images out to it, storing the location in a field in your DB. On Tuesday, September 24, 2002, at 08:46 AM, Salada, Duncan wrote: You can store pictures in a BLOB field, but it is generally recommended that you simply store the filename of the picture. I'm not shure, but is there a feature in oracle, which stores something like BLOBS internally as files? Is something like that planed in MySQL? -- [EMAIL PROTECTED] - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

Re: granting does not give the correct privileges
Is this an error in Mysql? I do the follwing command from a shell grant insert on mydb.* to username@localhost identified by user 'pwd'; When I check the permissions the insert_priv field on user table of mysql db is set to 'N'. Why is that? I can change the privileges by giving an update command. I did't understand exactly, but here a mistake I made: What plattform?

Tryout mysql++ Example Loading binary file in a BLOB ...
I wanted to test the mysql++ example Loading binary file in a BLOB ...
because I'm looking for for a solution to load several MB up to a remote DB,
without FTP or things like that. Just 1 thread in DB, so performance should
be no problem.
Therefor I try to execute and benchmark this quite famous Code from the
online-manual, but I've got some Problems (P) and Questions (Q).
I'm using Visual C++ 6 on an Windows98 , 526MHz and 320MB Ram.
I can compile in debug and release-Version. No errors, just warnings like, I
try to translate:
\include\type_info1.hh(39) : warning C4800: 'int' : Variable wird auf
booleschen Wert ('True' oder 'False') gesetzt
Integer set to boolean value true or false
\include\convert1.hh(40) : warning C4273: 'strtol' : Inkonsistente
DLL-Bindung. dllexport angenommen.
assumed inconsistent dll-binding for dllexport
\include\sql_query1.hh(135) : warning C4355: this' : wird in
Initialisierungslisten fuer Basisklasse verwendet
-this is used in init-lists for derived classses
\load_file.cpp(5) : warning C4273: '_errno' : Inkonsistente DLL-Bindung.
dllexport angenommen.
assumed inconsistent dll-binding
Q1: Can I do something against this warnings?
Q2: or are they taking any affect?
Then something curious: I can execute the code in Release-Mode and it runs
with no runtime error ( but the result is wrong , see below).
P1: When I run in in debug-Mode, I get an SQL-Syntax-Error 1064
Q3: Where can I find error-codes in the online-manual?
Q4: I'm not shure if std::string fill(read_buffer,blen);I included
std::string
P2:Unfortunally, the result ist not ok, since the escape manipulator
doesn't seem to do anything at all.
P3: I tried to fix the code for my VisualC++ compiler by inserting
#include string iostream , using namespace std; or adding std::
for debug-mode.
Then I get (often, not always) an Exception in line:
std::string tmp_str = strbuf.str();
release binary seems to be unchanged ...
This is a sample output of 2 runnings. file aaa contains now data to
escape, but abs does. both are ascii files.
// - OUTPUT
1st
C:\Bauinfo\Projekt_MySQL\mmd_source\Konsolentest\mysql_blob_load\Releasel
abc
release: loading ... abc
load data file: 0s
Length:20
kBytes/second: 1.#INF
// the cout of the whole query
INSERT INTO blobs (blob_data) VALUES(abc / 1 ' 2 3\
)
Error: You have an error in your SQL syntax near '3\
)' at line 1 1064
2nd
C:\Bauinfo\Projekt_MySQL\mmd_source\Konsolentest\mysql_blob_load\Releasel

release: loading ... aaa
load data file: 0s

INSERT INTO blobs (blob_data) VALUES(aaa bbb !§$%() 123 x-_
)
INSERT in MySQL: 0s

kBytes/second: 1.#INF
// END OF OUTPUT
P3) Uploaded Binary files cause no SQL-error, but are cut at the first '\0'.
therefore only some bytes are stored in BLOB (messured via phpmyadmin,
SELECT length(blob_data) ...
Has anybody compiled and tried out the original example?
