Re: Simple C API question
Thanks for the response..it was helpful. The information I was missing was that numeric values appear in MYSQL_ROW arrays as null-terminated strings, not as binary data.

Think of the Type VARCHAR. The length member of the FIELD tells you the maximum, the row gives you the string in the actual length. So far I know the Strings in the ROW are zero-terminated so you can use it with ease and the regular C-character-functions. http://www.mysql.com/doc/en/mysql_fetch_row.html Regards Bernhard - Original Message - From: Travis McLeskey [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, February 25, 2003 10:04 PM Subject: Simple C API question Question: Can I reliably interpret 'length' as the length in bytes of the corresponding byte string in the MYSQL_ROW, and is there a usual way to extract these data into regular C datatypes? - 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?

Simple C API question
Maybe this is a stupid question but I couldn't find suitable sample code or an answer in the manual. mysql_fetch_row() returns a MYSQL_ROW representation of a row of data. According to the manual, this is an array of counted byte strings. mysql_fetch_field() returns a MYSQL_FIELD with members 'type' and 'length', where 'length' is the width of the field, as specified in the table definition. Question: Can I reliably interpret 'length' as the length in bytes of the corresponding byte string in the MYSQL_ROW, and is there a usual way to extract these data into regular C datatypes?

Re: problem building mysql as an embedded server
Hi All, I am trying to run mysqld as an embedded server within my application. I have read the manual which says to run configure with --with-embedded-server option, but I have not succeded in building libmysqld.a. It builds all the remaining libs, but I don't find libmysqld.a anywhere within the install directory. The command I used is : ./configure --prefix=/home/dir --with-embedded-server=yes make make install I also tried, ./configure --prefix=/home/dir --with-embedded-server without any success in building libmysqld.a. Is this a bug ? Can anyone please help in resolving this ? Thanks, Ashok I'm guessing you are using the 3.23 source download. It's confusing because the documentation provided with the 3.23 source says that it can be configured with --with-embedded-server but, as far as I can tell, the embedded server was added with the 4.0 release. Anyway, binaries for the 4.0 embedded server are available for download. --- Travis McLeskey - [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?
