I am trying to access an AS-400 database using ODBC. So I created a DSN named "Test" and used the following as connection string

DSN=Test;SYSTEM=YYYYYYY;CMT=0;DBQ=XXXXXXX;NAM=0;DFT=5;DSP=1;TFT=0;TSP=0;DEC=0;XDYNAMIC=1;RECBLOCK=2;BLOCKSIZE=256;SCROLLABLE=0;TRANSLATE=0;LAZYCLOSE=1;LIBVIEW=0;REMARKS=0;CONNTYPE=0;SORTTYPE=0;LANGUAGEID=ENU;SORTWEIGHT=0;PREFETCH=1;DFTPKGLIB=QGPL;MGDS

Is there any way to acheive the above without creating the DSN?
