I'm working on convertion of sql from Teradata to snowflake, I've encoutered Normalize in sql with period(). Is there any equivalent in snowflake?
...
select normalize
id,
abc,
xyz,
period(time,
case
when
mtnt = mtnt_bb_l
and net_bb = net_bb_l
and DATEDIFF(MONTH,time,lead(time,1) over (....))>1
then add_months (time +1,1)
else lead(...)
end),
tms
from table
...
As you can see, normalize juste comme after select. is there any workround?

I need to create calculate table for the report in PowerBI Desktop.
I know how to do that in t-sql but I am unable to interpret it to DAX.
So should I use t-sql and add this query using "Get Data"?
Or should I create calculate table using DAX?
Which one is more efficient?
select distinct PolicyNumber,
ReserveStatus,
case when ReserveStatus = 'Open' then 1 else 0 end as OpenStatus
from RockhillClaimsDataFeed_PBI
group by PolicyNumber,ReserveStatus
Result looks like that:
can somebody help?
This is achievable by creating a calculated table in Power BI, with similar syntax using SELECTCOLUMNS and DISTINCT.
RockhillClaimsSummary =
DISTINCT(
SELECTCOLUMNS(
RockhillClaims,
"PolicyNumber", RockhillClaims[PolicyNumber],
"ReserveStatus", RockhillClaims[ReserveStatus],
"OpenStatus", IF(RockhillClaims[ReserveStatus] = "Open", 1, 0)
)
)

I am facing problem converting bellow query in spark-sql in pyspark
SQL-server query is
coalesce((Select top 1 f2.ChargeAmt from Fact_CMCharges f2
where f2.BldgID = f.BldgID
and f2.LeaseID = f.LeaseID
and f2.IncomeCat = f.IncomeCat
and f2.Period < f.Period
and f2.ActualProjected = 'Lease'
order by f2.Period desc),0) as Charge
I did not find replacing key word of top in pyspark sql . Kindly Help me
how could i convert this query in py-spark sql
Since you said Spark-SQL and if you have `DF', then you can use something like this.
df.limit(1).show()
I have a page that ask of users opinion about a topic. Their responses are then saved into a table. What I want to do is to check how many users selected an option 1,2,3 and 4.
What I have now are multiple T-SQL queries that run successfully but I believe there is a simplified version of the code I have written. I would be grateful if someone can simplify my queries into one single query. Thank you.
here is sample of data in the database table
enter image description here
$sql4 = "SELECT COUNT(CO) FROM GnAppItms WHERE CO='1' AND MountID='".$mountID."'";
$stmt4 = sqlsrv_query($conn2, $sql4);
$row4 = sqlsrv_fetch_array($stmt4);
$sql5="SELECT COUNT(CO) FROM GnAppItms WHERE CO='2' AND MountID='".$mountID."'";
$stmt5=sqlsrv_query($conn2,$sql5);
$row5=sqlsrv_fetch_array($stmt5);
$sql6="SELECT COUNT(CO) FROM GnAppItms WHERE CO='3' AND MountID='".$mountID."'";
$stmt6=sqlsrv_query($conn2,$sql6);
$row6=sqlsrv_fetch_array($stmt6);
$sql7="SELECT COUNT(CO) FROM GnAppItms WHERE CO='4' AND MountID='".$mountID."'";
$stmt7=sqlsrv_query($conn2,$sql7);
$row7=sqlsrv_fetch_array($stmt7);
You can do it by using group by in sql server
example :
create table a
(id int,
mountid nvarchar(100),
co int,
)
insert into a values (1,'aa',1)
insert into a values (2,'aa',2)
insert into a values (3,'aa',1)
insert into a values (4,'aa',2)
insert into a values (5,'aa',3)
Query
select co,count(co)as countofco from a
where mountid='aa'
group by
co
result
co countofco
1 2
2 2
3 1
Note : Beware of SQL injection when you are writing a sql query, so always use parametrized query. You can edit the above example code and make it as a parametrized query for preventing sql injection
I am doing queries over multiple databases in SQLite, and I'm having trouble using a .* in my queries. I have successfully used the ATTACH function to reference both databases:
dbOne.execute("ATTACH DATABASE 'dbOne.sql' as db1");
dbOne.execute("ATTACH DATABASE 'dbTwo.sql' as db2");
This query here gives me a syntax error (syntax error near *):
dbOne.execute("SELECT db2.myTable.* FROM db2.myTable");
Can I do db2.myTable.*? Or do I have to select each individual column one at a time?
SELECT db2.myTable.columnA, db2.myTable.columnB, db2.myTable.columnC, etc.
Thanks!
In case you have not solved this already, this will work:
a) dbOne.execute("SELECT * FROM db2.myTable");
b) dbOne.execute("SELECT abc.* FROM db2.myTable abc");
Also, you don't have to specify the database name when the tablename is unique across all attached databases.
b) is commonly used when you select or join multiple tables, e.g.
SELECT abc.*, xyz.* FROM db2.myTable abc, db1.myOtherTable xyz
I'm attempting to move a view between DB2 and SQL Server.
CREATE VIEW msu.bad_bus_cnty_st_mstr
AS
SELECT id,
bus_cnty_cntry_cd,
bus_st,
bus_zip
FROM summit.mstr
WHERE ( bus_cnty_cntry_cd, bus_st ) IN (SELECT cnty_cntry_cd,
st
FROM uhelp.cnty_cntry_cd
WHERE
cnty_cntry_descr LIKE '%invalid%');
The view works in DB2, but doesn't work with SQL Server because of the WHERE clause. Can I have a recommendation on how to rewrite this view to work with SQL Server?
It usually helps to define what "doesn't work" means (e.g. what error did you get) and also to specify the version of SQL Server you are using.
Unfortunately SQL Server doesn't support IN() with more than one clause. However you can re-write your view this way:
ALTER VIEW msu.bad_bus_cnty_st_mstr
AS
SELECT id,
bus_cnty_cntry_cd,
bus_st,
bus_zip
FROM summit.mstr AS mstr
WHERE EXISTS
(
SELECT 1
FROM uhelp.cnty_cntry_cd
WHERE cnty_cntry_descr LIKE '%invalid%'
AND cnty_cntry_cd = mstr.bus_cnty_cntry_cd
AND st = mstr.bus_st
);
one way
CREATE VIEW msu.bad_bus_cnty_st_mstr
AS
SELECT id,
bus_cnty_cntry_cd,
bus_st,
bus_zip
FROM summit.mstr m
WHERE EXISTS( SELECT 1 FROM uhelp.cnty_cntry_cd c
WHERE c.cnty_cntry_descr LIKE '%invalid%'
AND c.bus_cnty_cntry_cd = m.bus_cnty_cntry_cd
AND c.st = m.bus_st)
