Java API执行run函数和GUI中执行结果不一致
conn.login("admin","123456",false);
StringBuilder sb = new StringBuilder();
sb.append("'")
.append("F:"+File.separator+"dolphinDB2"+File.separator+"DolphinDB_GUI_V1.30.13"+File.separator+"workspace"+File.separator+"test1"+File.separator+"scripts"+File.separator+"GenTradeTable.txt")
.append("'") ;
Entity run = conn.run(sb.toString());
System.out.println("run.getString():"+run.getString());
txt
n=2000 syms=`YHOO`GE`MS`MSFT`JPM`ORCL`CISCO timestamp=09:30:00+rand(18000, n) sym=rand(syms, n) qty=100*(1+rand(100,n)) price=5.0+rand(100.0, n) t1=table(timestamp,sym,qty,price); t1
在GUI中可以看到结果如下
在Java API中只打印txt文件地址

可以这样理解，Java API的run方法的参数是字符串形式的脚本，和server的run函数不同。
正确代码如下：
DBConnection conn = new DBConnection();
conn.connect("localhost",8848,"admin","123456");
StringBuilder sb = new StringBuilder();
String script = "run(\"D:/work/GenTradeTable.txt\")";
System.out.println(script);
BasicTable res = (BasicTable) conn.run(script);
System.out.println("run.getString():"+res.getString());
