Compare dates from different records

[arpitkharkia]

Consider the following table:

LOAD * INLINE [

    GR, RT, QID, CD, Date

    1, 8, 11, 6/1/2017, 8/1/2017

    1, 10, 22, 9/1/2017, 8/1/2017

    1, 15, 33, 15/1/2017, 8/1/2017

    2, 9, 66, 4/1/2017,10/1/2017

    2, 12, 44, 8/1/2017, 10/1/2017

    2, 15, 55, 11/1/2017, 10/1/2017

];

If Date is greater than CD of the row and less than CD of the next row than that row has to be considered. For the above table i need the following output:

GR	RT	QID	CD	Date
1	8	11	6/1/2017	8/1/2017
2	12	44	8/1/2017	10/1/2017

I hope its possible. Help appreciated!

You need this in the script or front end?

[arpitkharkia]

I need this in the script itself. Need to join certain tables after that.

You may try this script:

tmp_table1:

LOAD * INLINE [

    GR, RT, QID, CD, Date

    1, 8, 11, 6/1/2017, 8/1/2017

    1, 10, 22, 9/1/2017, 8/1/2017

    1, 15, 33, 15/1/2017, 8/1/2017

    2, 9, 66, 4/1/2017,10/1/2017

    2, 12, 44, 8/1/2017, 10/1/2017

    2, 15, 55, 11/1/2017, 10/1/2017

];

tmp_table2:

load

GR, RT, QID, CD, Date, Peek(CD,RowNo(),'tmp_table1') as prevCD

Resident tmp_table1;

NoConcatenate

table1:

load *

Resident tmp_table2

where Date>CD and Date<prevCD

;

DROP Tables tmp_table1, tmp_table2;

Thanks for the reply! But the solution is not what i want.

You are welcome, but please explain why this is not what you want, maybe I didn't understand your requirement correctly.

Hi Arpit,

maybe this

Temp:
LOAD *,RowNo() as Rowno INLINE [
GR, RT, QID, CD, Date
1, 8, 11, 6/1/2017, 8/1/2017
1, 10, 22, 9/1/2017, 8/1/2017
1, 15, 33, 15/1/2017, 8/1/2017
2, 9, 66, 4/1/2017,10/1/2017
2, 12, 44, 8/1/2017, 10/1/2017
2, 15, 55, 11/1/2017, 10/1/2017
];
Temp1:
NoConcatenate LOAD *
Resident Temp
Where Date > CD and Date < Previous(CD)
Order By Rowno desc;
Drop Table Temp;
