why take empty result set row ? resultset row = dbmd.gettables("%", "dbuser1", "%", types); while (row.next()) { system.out.println(result.getstring(1)); } you can use code : try { //must upper case string username="dbuser1".touppercase(); resultset row = dbmd.gettables("%", username , "%", types); while (row.next()) { //you need table name trigger name result.getstring("table_name"); } //catch errors } catch (sqlexception e) { while (e != null) { system.out.println("\n message: " + e.getmessage()); system.out.println("\n sqlstate: " + e.getsqlstate()); system.out.println("\n errorcode: " + e.geterrorcode()); e = e.getnextexception(); } }

does 1.0e+1 return float value or int value? when print 1.0e+1 gives 10 when sizeof(1.0e+1) gives me 8 . does 1.0e+1 return float value or int value? ans: none. written, represents double . nitpick: let's use term represent instead of return i think you're confused. ihmo, need know proper usage of conversion specifiers. to print float, need use %f to print sizeof output, need use %zu that said, printing 1.0e+1 means printing value whereas, sizeof(1.0e+1) sizeof(double) , because, floating point literal default double . related, c11 standard, chapter §6.4.4.2 an unsuffixed floating constant has type double . if suffixed letter f or f , has type float . if suffixed letter ``l or l , has type long double .
