SQL Server常用存储过程及示例

/*分页查找数据*/
CREATE PROCEDURE [dbo].[GetRecordSet]
@strSql varchar(8000),--查询sql,如select * from [user]
@PageIndex int,--查询当页号
@PageSize int--每页显示记录
AS
set nocount on
declare @p1 int
declare @currentPage int
set @currentPage = 0
declare @RowCount int
set @RowCount = 0
declare @PageCount int
set @PageCount = 0
exec sp_cursoropen @p1 output,@strSql,@scrollopt=1,@ccopt=1,@rowcount=@rowCount output --得到总记录数
select @PageCount=ceiling(1.0*@rowCount/@pagesize) --得到总页数
,@currentPage=(@PageIndex-1)*@PageSize+1
select @RowCount,@PageCount
exec sp_cursorfetch @p1,16,@currentPage,@PageSize
exec sp_cursorclose @p1
set nocount off
GO

unity3d脚本全新开启

/*
用户注册，也算是添加吧
*/
Create proc [dbo].[UserAdd]
(
@loginID nvarchar(50), 　　　　--登录帐号
@password nvarchar(50), --密码
@email nvarchar(200) --电子信箱
)
as
declare @userID int --用户编号
--登录账号已经被注册
if exists(select loginID from tableName where loginID = @loginID)
begin
return -1;
end
--邮箱已经被注册
else if exists(select email from tableName where email = @email)
begin
return -2;
end
--注册成功
else
begin
select @userID = isnull(max(userID),100000)+1 from tableName
insert into tableName
(userID,loginID,[password],userName,linkNum,address,email,createTime,status)
values

SQL Server 系统存储过程

Create table T2 (id int , name char (20))
GO
EXEC sp_addextendedproperty 'MS_Description', 'Employee ID', 'user', dbo, 'table', T2, 'column', id
EXEC sp_updateextendedproperty 'MS_Description', 'this is a test', 'user', dbo, 'table', T2, 'column', id

2.修改数据库名称

Create table T2 (id int , name char (20))
GO
EXEC sp_addextendedproperty 'MS_Description', 'Employee ID', 'user', dbo, 'table', T2, 'column', id
EXEC sp_updateextendedproperty 'MS_Description', 'this is a test', 'user', dbo, 'table', T2, 'column', id

2.修改数据库名称

EXEC sp_renamedb 'old_db_name', 'new_db_name'

3.修改数据表名称和字段名称

EXEC sp_rename 'old_table_name', 'new_table_name'–修改数据表名称
EXEC sp_rename 'table_name.[old_column_name]', 'new_column_name', 'COLUMN'–修改字段名称
