Suppose we need to find out the name of all the months in a given year (Year will be given as an input parameter) where first day of the month falls on weekend (Saturday or Sunday).
So what should be the query/stored procedure to get the above result?
create proc techmixing_8_4_14 @yr as numeric
as
SET NOCOUNT ON;
set datefirst 1 — to set first day as monday
declare @dt as varchar(8);
declare @count as numeric=1
create table #t1 (mn varchar(20)) — Temporary table
while @count <=12
begin
set @dt=convert(varchar(4),@yr ) + isnull(REPLICATE('0',2-len(convert(varchar(2),@count))),'')+convert(varchar(2),@count)+ '01'
set @count=@count+1
if datepart(dw,convert(date,@dt,112 )) >=6
begin
insert into #t1 (mn) select datepart(MM,@dt)
end
end
select * from #t1
go
exec techmixing_8_4_14 2012
To get month name, we can also replace datepart with datename in below statement :
insert into #t1 (mn) select datepart(MM,@dt)
Really Good Answer Bharat.. Keep it up
Just to little modify the Bharat answer by adding "No count off" in the end.
Create proc techmixing_8_4_14 @yr as numeric
as
begin
SET NOCOUNT ON;
set datefirst 1 — to set first day as monday
declare @dt as varchar(8);
declare @count as numeric=1
create table #t1 (mn varchar(20)) — Temporary table
while @count <=12
begin
set @dt=convert(varchar(4),@yr ) + isnull(REPLICATE('0',2-len(convert(varchar(2),@count))),'')+convert(varchar(2),@count)+ '01'
set @count=@count+1
if datepart(dw,convert(date,@dt,112 )) >=6
begin
insert into #t1 (mn) select datename(MM,@dt)
end
end
select * from #t1
set nocount off
end
go
exec techmixing_8_4_14 2012
Declare @Months Varchar(60)
Declare @loop int
SET @loop=1
WHILE @loop<=12
BEGIN
IF(Datename(dw,'2014/'+str(@loop)+'/1') in ('Saturday','Sunday'))
BEGIN
SET @Months=COALESCE(@Months+ ', ', '')+ DateName( month , DateAdd( month , @loop , 0 ) -1)
END
SET @loop=@loop+1
END
Print @Months
