Example of JSP calling SQL Server Stored Procedure:

Create a table:

Reference content is as follows:
Create table [BookUser] (
[UserID] [int] IDENTITY (1, 1) not null,
[UserName] [varchar] (50) COLLATE Chinese_PRC_CI_AS not null,
[Title] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS not null,
[Guid] [uniqueidentifier] not null constraint [DF_BookUser_Guid] DEFAULT (newid ()),
[BirthDate] [datetime] not null,
[Description] [ntext] COLLATE Chinese_PRC_CI_AS not null,
[Photo] [image] NULL,
[Other] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL
CONSTRAINT [DF_BookUser_Other] DEFAULT ('default '),
CONSTRAINT [PK_BookUser] PRIMARY KEY CLUSTERED
(
[UserID]
) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

Create a stored procedure:


Reference content is as follows:
Create procedure InsertUser
@ UserName varchar (50 ),
@ Title varchar (255 ),
@ Guid uniqueidentifier,
@ BirthDate DateTime,
@ Description ntext,
@ Photo image,
@ Other nvarchar (50 ),
@ UserID int output
As

Set NOCOUNT ON
If Exists (select UserID from BookUser Where UserName = @ UserName)
RETURN 0
ELSE
Begin
Insert into BookUser (UserName, Title, Guid, BirthDate, Description, Photo, Other)
VALUES (@ UserName, @ Title, @ Guid, @ BirthDate, @ Description, @ Photo, @ Other)
SET @ UserID = @ IDENTITY
RETURN 1
End
GO


JSP code:

Reference content is as follows:
<% @ Page language = "java" contentType = "text/html; charset = UTF-8" pageEncoding = "UTF-8" %>
<% @ Page import = "java. SQL. *" %>
<! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Transitional // EN"

String url = "jdbc: sqlserver: // localhost: 1433; databaseName = Book; user = sa; password = ";
String SQL = "{? = Call InsertUser (?,?,?,?,?,?,?,?)} ";
Connection cn = null;
CallableStatement cmd = null;
Try
{
Cn = DriverManager. getConnection (url );
Cmd = cn. divpareCall (SQL );
Java. util. UUID Guid = java. util. UUID. randomUUID ();
String FilePath = application. getRealPath ("") + "\ test \ logo.gif ";
Java. io. FileInputStream f = new java. io. FileInputStream (FilePath );
Date rightNow = Date. valueOf ("2007-9-9 ");
Cmd. setString ("UserName", "mengxianhui ");
// Note that the Stored Procedure verifies the uniqueness of UserName.
Cmd. setString ("Title", "Meng xianhui ");
Cmd. setString ("Guid", Guid. toString ());
Cmd. setString ("BirthDate", "2007-9-9 ");
Cmd. setDate ("BirthDate", rightNow );
Cmd. setString ("Description", "Chapter E of Mencius ]");
Cmd. setBinaryStream ("Photo", f, f. available ());
Cmd. setString ("Other", null );
Cmd. registerOutParameter (1, java. SQL. Types. INTEGER );
Cmd. registerOutParameter ("UserID", java. SQL. Types. INTEGER );
Cmd.exe cute ();
Int returnValue = cmd. getInt (1 );
Int UserID = cmd. getInt ("UserID ");
If (returnValue = 1)
{
Out. print ("<li> added successfully! ");
Out. print ("<li> UserID =" + UserID );
Out. print ("<li> returnValue =" + returnValue );
}
Else
{
Out. print ("<li> failed to add! ");
}
F. close ();
}
Catch (Exception ex)
{
Out. print (ex. getLocalizedMessage ());
}
Finally
{
Try
{
If (cmd! = Null)
{
Cmd. close ();
Cmd = null;
}
If (cn! = Null)
{
Cn. close ();
Cn = null;
}
}
Catch (Exception e)
{
E. printStackTrace ();
