Double Loop? Exist()? some way else?

Tue, 01 Sep 2015 07:52:45 GMT

Hello,

I want to do a matching for two tables, aiming to create a flag. The 2 tables look like following:

Table 1:

Board Nr.	Planned Method
a1	A
a1	C
a1	D
a2	A
a2	B
a2	D
a2	F
a3	C
a3	E

Table 2:

Appointment Index	Board Nr.	Used Method	Flag
1	a1	C	1
		D
		A
		F
2	a3	B	0
		D
3	a3	C	0
4	a2	A	0
		B
		D
		E
5	a1	A	1
		C
		D
6	a3	C	1
		E

For each board, there are planned methods (see Table 1). However, the actually used methods in each appointment may not be as planned and each appointment must belong to one board (see Table 2). When there is at least one planned method not being used, we mark the flag as 0; when all planned methods are used, mark as 1. Could anyone help me with this match? Thank you in advance.

Regards, Luwen

Try Like this

load [Board Nr.],concat([Planned Method],',') as [Planned Method]

group by [Board Nr.];

load * Inline

[

Board Nr.,Planned Method

a1,A

a1,C

a1,D

a2,A

a2,B

a2,D

a2,F

a3,C

a3,E

];

join(A)

load [Appointment Index],[Board Nr.],Concat([Used Method],',') as [Used Method]

Group by

[Appointment Index],[Board Nr.];

load * Inline

[

Appointment Index,Board Nr.,Used Method

1,a1,C

1,a1,D

1,a1,A

1,a1,F

2,a3,B

2,a3,D

3,a3,C

4,a2,A

4,a2,B

4,a2,D

4,a2,E

5,a1,A

5,a1,C

5,a1,D

6,a3,C

6,a3,E

];

NoConcatenate

final:

load *,if(SubStringCount([Used Method],[Planned Method])>0,1,0) as flag Resident A;

drop Table A;
