[英]Detect whether the connection exists between fields in Dynamics-AX-2012
I have two tables, table1(fields: playerId, insuranceId) and table2. 我有两个表,table1(字段:playerId,insuranceId)和table2。
How to determine from table2 if the playerId and insuranceId have a connection to each other? 如何从表2中确定playerId和insuranceId是否相互连接?
I mean which player have agreement with which insurance company... 我的意思是哪个球员与哪个保险公司达成协议...
I know that I should override method(which one?) in table to and use table1 exist method to make it work, but I don't know how to do it. 我知道我应该重写表中的方法(哪个?)并使用table1存在的方法来使其工作,但我不知道该怎么做。
I don't sure I understand you correctly, but you create next method on table2 我不确定我是否正确理解您,但是您在table2上创建了下一个方法
public boolean existInTable1()
{
table1 t;
;
select recid from t where t.playerid == this.playerid && t.insuranceid == this.insuranceid;
return (t.recid !== 0);
}
And somewhere in code: 在代码中的某处:
table2 t2;
;
select t2;
if(t2.existInTable1()) ...
Updated 更新
Of course, if you have exist-method on table1 you can rewrite existInTable1() like this: 当然,如果在table1上存在存在方法,则可以像下面这样重写existInTable1():
public boolean existInTable1()
{
;
return table1::exist(this.playerid, this.insuranceid);
}
