Need assistance in script to get the first record -

Hi there,

Please help me with the script.

SE_TMP:
Load
[Facility Identifier],
"Derived National Service Event Record Id",
"SE.Service Event Record ID",
1 as count_se
1 as count_oos
FROM
QVD;

SE:
NoConcatenate
LOAD DISTINCT
"OOS.Derived National Service Event Record Id" as IDKey,
[Facility Identifier],
"SE.Service Event Record ID",
1 as count_se
0 as count_oos
RESIDENT OOS
WHERE NOT EXISTS ("Derived National Service Event Record Id","OOS.Derived National Service Event Record Id")
;

Concatenate(SE)
LOAD
"Derived National Service Event Record Id" as IDKey,
"Facility Identifier"
,"SE.Service Event Record ID"
,count_se as SE.count_se
,count_moh_se as SE.count_moh_se
RESIDENT SE_TMP;

DROP TABLE SE_TMP;

from the middle script , I am getting two records becoz of different SE.Service Event Record ID .i.e below script

Is there any way I get the every first row the the distinct record in RESIDENT table ?

This is an eg , I have to get the distinct record depending on erived National Service Event Record Id not Service Event Record ID. I can understand why my distinct is not working becoz this are two record because of Service Event Record ID

Is there any way in qlikview script where I can only pick the first record ?

You can use the LOAD prefix First n to select the first n rows.

First 1

I would think you can just create a new dummy field as you load to use in Not Exists(). For example.

Data:
LOAD * INLINE [
Id, Name
abc, Rob
abc, Sally
def, John
def, Linda
zzz, Ralph
]
;

Firsties:
LOAD
*,
Id as FirstId
Resident Data
Where Not Exists(FirstId, Id)
;

DROP Table Data;
DROP Field FirstId;
