Bug #10549: Performance problem with Openlink ODBC drivers

From: a.vdvelden@it.correct.nl Operating system: Suse Linux 6.2 PHP version: 4.0.4pl1 PHP Bug Type: Performance problem Bug description: Performance problem with Openlink ODBC drivers Hello, I've experienced a compilation error and some huge performance problems setting up an ODBC connection via Openlink ODBC drivers. I've configured my Php: ./configure --with-openlink=/usr/src/openlink When compiling Php, it complains about missing the iodbc.h udbcext.h header files which are not included in the SDK software package of Openlink. When I remove the two above include files from ./ext/odbc/php_odbc.h line 125 128 the compilation works fine without errors or warnings, and am able to etablish a connection to my Openlink drivers. When I query my DB from out of Php via Openlink, a simple query takes huges amounts of time, while the same query is very fast using the included odbctest utility from the Openlink SDK package. I've run a query via Php and the odbctest utility and compared the two debug files and saw that Php uses the ExtendedSQLFetch C- function. The odbctest utility uses an 'normal' SQLFetch function. So I have changed my ./ext/odbc/php_odbc.h file line 124 from: #elif defined(HAVE_OPENLINK) /* OpenLink ODBC drivers */ #define ODBC_TYPE "Openlink" #include <iodbc.h> #include <isql.h> #include <isqlext.h> #include <udbcext.h> #define HAVE_SQL_EXTENDED_FETCH 1 #define SQLSMALLINT SWORD #define SQLUSMALLINT UWORD to: #elif defined(HAVE_OPENLINK) /* OpenLink ODBC drivers */ #define ODBC_TYPE "Openlink" // #include <iodbc.h> #include <isql.h> #include <isqlext.h> // #include <udbcext.h> // #define HAVE_SQL_EXTENDED_FETCH 1 #undef HAVE_SQL_EXTENDED_FETCH #define SQLSMALLINT SWORD #define SQLUSMALLINT UWORD With this small change I was able to compile my Php succesfully and query my Database via the Openlink Package very fast!
