webservice proxy dll

pankajmittal — Fri, 07 Oct 2011 10:07:14 +0000

Please run these two commands in visual studio command prompt one by one.

Wsdl /language:CS /username:sa /password:XXXXX http://192.168.1.X/serwebservice/Service.asmx /n:XXXSmsService /o:XXXSmsService.CS
After generating result run this query.

csc /t:library /out:XXXSmsService.dll XXXSmsService.CS

This will generate a class file and a dll on below path.

Go To “C:\Program Files\Microsoft Visual Studio 9.0\VC” there you will find XXXSmsService.CS and XXXSmsService.dll.

Enjoy :)

Get Comma Separated values from table without using Function

pankajmittal — Fri, 07 Oct 2011 06:00:30 +0000

Many times you come across a situation where you have to convert values stored in multiple rows in a comma separated string e.g. Part consumed in a job.

Using Coalesce you can achieve the same but the drawback is that it would hit the performance significantly if you need to call this function for each row in a recordset. Actually using any function when it needs to be applied to each row will hit query performance unless the rows returned are not too many !

As an alternate to Coalesce, you can use For XML construct which will give better performance if your recordset is large.

Sample :

SELECT t1.ID ,

SUBSTRING(( SELECT ( ‘ ,’ + t2.Part )

FROM dbo.PartConsumed t2

WHERE t1.ID = t2.ID

FOR

XML PATH(”)

), 3, 500) AS PartUsed

FROM dbo.PartConsumed t1

GROUP BY t1.ID

calculate sunday between two dates

–Pass two dates and it how many sundays occures
CREATE FUNCTION [dbo].[fnc_SundayCount](@StartDate datetime,@EndDate datetime)
RETURNS SMALLINT
as
Begin
SET @StartDate=CONVERT(datetime,CONVERT(VARCHAR, @StartDate,101))
SET @EndDate=CONVERT(datetime,CONVERT(VARCHAR, @EndDate,101))
DECLARE @DayDiff SMALLINT
DECLARE @tempVar SMALLINT
DECLARE @TotalSunday SMALLINT
SET @TotalSunday=0
SET @DayDiff=DATEDIFF(DAY,@StartDate,@EndDate)
SET @tempVar=0
WHILE (@tempVar < @DayDiff)
BEGIN
IF(DATEPART(weekday,@StartDate)=1)
BEGIN
SET @TotalSunday =@TotalSunday+1
END
SET @StartDate=@StartDate+1
SET @tempvar = @tempvar+1
END
Return @TotalSunday
END

performance of your queries

Implicit Conversion can hit performance of your queries

If there is data type mismatch in the type of table field and the variable you use in where clause, the query will result in table or index scan instead of index seek even when there is a proper index on the field used in the where clause.

This is because SQL server will do implicit conversion by using the function on the field. Eg. if your table field is varchar and you define parameter as nvarchar, if you write something like below

declare @var1 nvarchar(20)=’test’
select * from table1 where field1=@var1

it will actually work like

select * from table1 where convert(nvarchar(20),field1) = @var1.
Thus any index on field1 will be ignored and a scan operation will run.
Be aware of this and use proper data types for your variables.

Also note the implicit conversion issue is not limited to field vs. variable..it will happen as well if you compare two fields with different data types..thus if same you have field in multiple tables, came the data type as same.
