  1. I have not resolved the problem yet. After tracing, I found two different test way caused different call of "mysql_init" and other mysql client api: When I use "a.out" built from C source code (a.out->my.so->iodbc->myodbc->mysql) to test, it used "mysql-init" within the libmysqlclient.so. When I use "php test.php" (php->my.so->iodbc->myodbc->mysql) to test, it used "mysql_init" within "php". "php" client contained a "mysql_init" from its "ext/mysql". So strange. And I have not found how to deal with it. Please help me.
  2. I traced into myodbc and found it was caused by charset setting. When I use exec-file built from C source code to test, the charset is "latin1". And when I use "php test.php" to test, the charset struct parameter is null pointer. SQLDriverConnect passed but SQLExecDirect failed. When SQLDriverConnect, "mysql_real_connect" said: | | | >get_charsets_dir | | | | info: charsets dir='NONEXISTENT/charsets/' I configed the php.ini and add "default-charset=latin1". But the failure is the same. Who can tell me how to set the charset for php->odbc->mysql?
  3. I used PHP->"C++ shared object(*.so)"->unixODBC->myodbc->mysql architecture. I executed "php test.php" at command line. Then I got "segment fault" on tty. I apply ODBC trace log. I found SQLConnect succeeded but SQLExecDirect was failed at the first "SELECT" statement. I traced into unixODBC and found no return from myodbc's SQLEXECDIRECT. It seems dead in myodbc. I had not traced into myodbc since no source code of myodbc. I installed myodbc with binary code. Furthermore, I used "C binary: main()"->"C++ shared object(*.so)"->unixODBC->myodbc->mysql architecture to test. Everything is OK. SQLExecDirect succeeded at every "SELECT" statement. The "SELECT" statement is the same as php execution mode. I saw they are coincident in ODBC trace log. The environment is: Login linux with "root". Connect ODBC with "DSN=testdb;UID=root;PWD=;". There is no password for "root" of mysql.
