獲取最近6個月數據的腳本

嗨，

 

什麼是最好的腳本只選擇精確的數據過去6個月每次更新數據庫。 

回复：腳本獲取最近6個月的數據

這取決於您對“數據庫”的含義以及哪種工作流最適合您正在處理的數據，但是，如果您在JMP表中有數據，則可以執行以下操作：

 

NamesDefaultToHere(1);

// Make some 'date' data to play with
JMPstartDate = DateDMY(01,1,2013);
JMPendDate = Today();
dt = NewTable("DateTimes", 
  NewColumn("Date", Numeric, Continuous, 
   Formula(RandomInteger(JMPstartDate, JMPendDate)), 
   Format( "ddMonyyyy h:m:s", 22, 0 )
   ),
  AddRows(1000)
  );
dt << runFormulas;
Column(dt, "Date") << deleteFormula;
dt << sort(By(:Date), replaceTable);

// Exclude and hide all rows older than six months ago:
// Look for 'DateIncrement()' in 'Help > scripting Guide'.
cutoff = Date Increment( Today(), "Month", -6, "actual" );
dt << selectWhere(:Date < cutoff);
dt << hideAndExclude;
dt << clearSelect;
