Test Stored Procedure Manually in MS SQL

Write a stored procedure  eg :  sp_Insert_Client_info

Now on New Query window  execut it with stored procedure's required value,

 like this  sp_Insert_Client_info'Age','India','phone',10101

Above sp will take 3 arguments/values :

1. Age  or text value
2. India or Text vale
3. 10101  or integer value

Another example:

 sp_Insert_Client_Info'Jhon','sharma',87

Casting date & time to datetime in SQL

Casting & concatenating date & time field of a table to datetime & perform a datetime search query

Okey its a quick post.We will get date & time separably from C# & we will concatenating in DB as a datetime & perform a search query.


In C# to SQL 

Suppose  variable 1=11/9/2011 10:53:00 AM

V2=11/9/2011 12:42:50

In table we have two fields  like one is date & second is time  .Now we will cast them in to Datetime & search with datetime parameter of C#

--[sp_checkFlights]'11/9/2011 10:53:00 AM','11/9/2011 12:42:50'

ALTER PROCEDURE [dbo].[sp_checkFlights]

(

@gmtnow datetime,

@addedtime datetime

)

AS

BEGIN

SET NOCOUNT ON;

SELECT *

FROM tbl_sms_record

WHERE CONVERT(datetime, Convert(varchar, FlightDate) + ' ' + Convert(varchar(8), SchedularDepartureTime))

BETWEEN @gmtnow AND @addedtime

END

(
@uname varchar(100),
@password varchar(100)
)
As
declare @pass varchar(100)
select @pass=password from tbl_user where user_name=@uname
if(@pass=@password)
begin
select user_id,role,type from tbl_user where user_name=@uname and password=@pass
end
else
begin
select 0 as user_id
end

If - Else in T-SQL

Its an example of a simple stored procedure using IF-Else in SQL .

First of all,we declared a variable ( @cnt ) to count no of rows that matches the condition ( @cnt=COUNT(*) ).

Select @cnt=COUNT(*) from tbl_X where AirlineCode = @AirlinesCode AND DestinationCode = @DestinationCode


Structure of IF Else like this :-

IF @cnt=0
Then
Insert New Record
Else
Update the Existing Record


Stored Procedure would be :-


USE [XXX]
GO



Create PROCEDURE [dbo].[sp_Admin_InsertIncreasedFare]


@AirlinesCode varchar(100),
@DestinationCode varchar(100),
@Amount decimal(18, 2)


AS
BEGIN

SET NOCOUNT ON;

declare @cnt int=0;

Select @cnt=COUNT(*) from tbl_X where AirlineCode = @AirlinesCode AND DestinationCode = @DestinationCode

-- If loop--
IF @cnt=0

Begin

Insert into tbl_X (AirlineCode,DestinationCode,Amount) VALUES (@AirlinesCode,@DestinationCode,@Amount)

END

Else

Begin

Update tbl_X Set Amount=@Amount where AirlineCode = @AirlinesCode AND DestinationCode = @DestinationCode

END

END
