com.ibm.db2.jcc.am.sqlsyntaxerrorexception: db2 sql error: sqlcode=-204, sqlstate=42704, sqlerrmc=root.employee, driver=3.63.123     @ com.ibm.db2.jcc.am.fd.a(fd.java:679)     @ com.ibm.db2.jcc.am.fd.a(fd.java:60)     @ com.ibm.db2.jcc.am.fd.a(fd.java:127)     @ com.ibm.db2.jcc.am.ho.c(ho.java:2644)     @ com.ibm.db2.jcc.am.ho.d(ho.java:2632)     @ com.ibm.db2.jcc.am.ho.a(ho.java:2097)     @ com.ibm.db2.jcc.t4.cb.h(cb.java:141)     @ com.ibm.db2.jcc.t4.cb.b(cb.java:41)     @ com.ibm.db2.jcc.t4.q.a(q.java:32)     @ com.ibm.db2.jcc.t4.sb.i(sb.java:135)     @ com.ibm.db2.jcc.am.ho.gb(ho.java:2066)     @ com.ibm.db2.jcc.am.ho.a(ho.java:3120)     @ com.ibm.db2.jcc.am.ho.a(ho.java:681)     @ com.ibm.db2.jcc.am.ho.executequery(ho.java:665)

code:

      class.forname("com.ibm.db2.jcc.db2driver");                                    system.out.println("**** loaded jdbc driver");          string url = bundle.getstring("db2.url");           string user = bundle.getstring("db2.username");           string password = bundle.getstring("db2.password");        // create connection using ibm data server driver jdbc , sqlj       connection con = drivermanager.getconnection (url, user, password);                       // commit changes manually       con.setautocommit(false);       system.out.println("**** created jdbc connection data source");        // create statement       statement stmt = con.createstatement();                                                  system.out.println("**** created jdbc statement object");        // execute query , generate resultset instance       resultset rs = stmt.executequery("select empno  employee");                          system.out.println("**** created jdbc resultset object");        string empno;           // print of employee numbers standard output device       while (rs.next()) {         empno = rs.getstring(1);         system.out.println("employee number = " + empno);       }       system.out.println("**** fetched rows jdbc resultset");       // close resultset       rs.close();       system.out.println("**** closed jdbc resultset");        // close statement       stmt.close();       system.out.println("**** closed jdbc statement");               if(con!=null){system.out.println("connection successfull db2");}

the problem not connection. need understand how read db2 error messages.

in part problem explained:

sqlcode=-204, sqlstate=42704, sqlerrmc=root.employee

in means, established connection, , when looking object root.employee, db2 did not find anything. error 204, can interpreted sql0204. in db2clp or internet , got answer.

it seems problem connecting root database, , implicit schema 'root' not contain employee table. make sure using right schema.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
