PeopleCode筆記（一）

PeopleCode變數名都以&開頭，預設的局部變數類型為ANY。當返回資料類型不確定時為ANY，由PeopleTools決定其類型。

 

Local Any &Example_Any;
Local String &Test;
Local String &Test2;

 

&Example_any = "TEST";

&Example_Any = &Test | ' ' | &Test2;

 

/*%Date：今天*/

&Example_any = %Date;

 

BOOLEAN: TRUE(1) or FALSE(0).

 

LOCAL BOOLEAN &B_test;
&B_test = False;

 

DATE: YYYY-MM-DD

DATETIME: YYYY-MM-DD-HH.MI.SS.SSSSSS

TIME: HHMISS

 

NUMBER: 整數或者小數

 

&Number_example1 = 456;
&Number_example2 = 456.78;
&Number_example3 = 0.45678;
&Number_example4 = -456.78;

 

FLOAT: 浮點小數

 

INTEGER: 整數，32位有符號數；PeopleCode中除法運算即使定義成INTEGER不會用到INTEGER，而是用浮點數

 

Local INTEGER &Sample1, &Sample2, &Sample3;
&Sample1 = 44;
&Sample2 = 11000;
&Sample3 = -2200;

 

STRING: 可以使用單引號或者雙引號

 

&sample_string = "Now is the time for all good men to come to the aid of their country";
&sample_string2 = "Now is the time for all good men to come to the aid of their country 'string within a string' declaration";
&sample_string3 = "Now is the time for all good men to come to the aid of their country "double quoted string within a string" declaration";
