That code will help to developer to develop code to run Stored Procedure easily from .Net (if you built it .dll file). Any one can write just few lines code to use it. If any one get any bug then please inform me at firstname.lastname@example.org. To know more about such programming please visit to my blog http://socketprogramming.blogspot.com.
When I try to run stored procedure from C# then I see that to run a single stored procedure need to write few line of code also to pass parameter need to write more line of code. So i decide to write some code by using stored procedure can run very fast. And now my code can run a Stored procedure by invoke just one function, and per parameter just one line code.
Use this code to run stored procedure
You can run any stored
procedure by invoking two static methods. These are -
spArgumentsCollection - this is a static method of SP class, used to
pass arguments to stored procedure. It has four arguments, for example, SP.spArgumentsCollection(arLst, "@nextName",
"Suman Biswas", "varchar"); here ‘SP’ is the class name, ‘arLst’ is an ArrayList, “@nextName” is
arguments name in Stored Procedure, “Suman Biswas” is the value of argument and
“varchar” is argument type (in version 2, this has updated to enum type).
RunStoredProcedure- this is used to run
stored procedure. If stored procedure has argument then need to set argument(s)
in ArrayList then have to call that method. For e.g. SP.RunStoredProcedure(cnnStr, "UpdateName",
arLst); Here ‘cnnStr’ is connection string of BD, “UpdateName” is stored
procedure name and arLst is ArrayList of arguments. By this array list
arguments’ value passed to stored procedure. This has one more overload method,
with extra argument DataSet, to use it’s DataTable to store retrieved value.
How this code actually works
SP class has one subclass SPArgBuild which helps to pass argument to Stored
Procedure. When spArgumentsCollection method
called then it internally creates an object of SPArgBuild, and set passed value
to new objects’ attribute then return that object, which holds as an ArrayList
element (here in arLst), and return ArrayList. In this way ArrayList holds
Stored Procedure’s all argument.
Next when RunStoredProcedure called then data are retrieve from ArrayList and these set to command
object’s parameter. Then send commend to execute Stored Procedure.
An example by executing a sample Stored
To run that code we will follow
these steps –
CREATE TABLE client(
id int IDENTITY(1,1) NOT NULL,
Name varchar(64) NULL,
jdate datetime NULL
some rows in there
INSERT INTO client(Name,jdate)VALUES ('Taniya',getdate())
INSERT INTO client(Name,jdate)VALUES ('Jhuma',getdate())
INSERT INTO client(Name,jdate)VALUES ('Ganesh',getdate())
create procedure UpdateName ( @nextName varchar(256), @id int )
update client set name=@nextName where id=@id
procedure by my code.
ArrayList arLst = new ArrayList();SP.spArgumentsCollection(arLst, "@nextName", "Suman Biswas", "varchar");
SP.spArgumentsCollection(arLst, "@id", "2", "int");
SP.RunStoredProcedure(cnnStr, "UpdateName", arLst);
Now code is completed try it now.
