USQL query for SELECTING a range from a table - u-sql

Question

Data is as
index id
1 112
1 112
2 109
2 109
3 125
3 125
4 199
4 199
5 100
5 100
The id are not incremental but are sequential in nature take it as a GUID that's why i have assigned index for Range query
The user will give #startid #endid and i will get the rows for this range
Now first i get the index corresponding these id like
#indexes = SELECT DISTINCT index
FROM #table
WHERE id IN (#startid, endid);
as a result i get (let's say for example if #startid = 2 and #endid = 4)
2
4
Now i know the Range will be BETWEEN 2 and 4 i.e. i want rows corresponding 2,3 and 4
#result= SELECT index AS index,
id AS id
FROM #data
WHERE
index BETWEEN (THE TWO ENTRIES FROM #indexes)
would have done this using Nested SELECT but USQL doesn't support it.
now is there a way to treat #indexes as a list and specify range or something???

Answer 1

BETWEEN is supported in U-SQL, it's just case-sensitive, eg
DECLARE CONST #startId int = 2;
DECLARE CONST #endId int = 4;
#input = SELECT *
FROM (
VALUES
( 1, 112 ),
( 1, 112 ),
( 2, 109 ),
( 2, 109 ),
( 3, 125 ),
( 3, 125 ),
( 4, 199 ),
( 4, 199 ),
( 5, 100 ),
( 5, 100 )
) AS x ( index, id );
#output =
SELECT *
FROM #input
WHERE index BETWEEN #startId AND #endId;
OUTPUT #output TO "/output/output.csv"
USING Outputters.Csv(quoting:false);
My results:
Alternative approach:
DECLARE CONST #startId int = 109;
DECLARE CONST #endId int = 199;
#input = SELECT *
FROM (
VALUES
( 1, 112 ),
( 1, 112 ),
( 2, 109 ),
( 2, 109 ),
( 3, 125 ),
( 3, 125 ),
( 4, 199 ),
( 4, 199 ),
( 5, 100 ),
( 5, 100 )
) AS x ( index, id );
#output =
SELECT i. *
FROM #input AS i
CROSS JOIN
(
SELECT MIN(index) AS minIndex,
MAX(index) AS maxIndex
FROM #input AS i
WHERE id IN ( #startId, #endId )
) AS x
WHERE i.index BETWEEN x.minIndex AND x.maxIndex;
OUTPUT #output TO "/output/output.csv"
USING Outputters.Csv(quoting:false);
