Question

我想根据前缀创建一个联合特定表的视图它是在SQL 2008服务器上运行的数据库。

表名如下：
Table_XXX_13_1 ; Table_XXX_14_2 ;Table_XXX_15_3 ; Table_XXX_15_4 ...等

新视图名称：'View_XXX_15'

我该怎么办？我想过滤“Table_XXX_15%”，尝试使用选择内容，
请列出一些信息，我是SQL的新手。

以下代码不起作用：

    CREATE PROCEDURE spCreateView2015 
            @BaseTableName varchar(100),
            @View varchar(100),
            @s varchar(max),
            @v varchar(max)

AS
BEGIN
        SET NOCOUNT ON;
        set @BaseTableName = 'Table%15%';
        set @View = 'View_097_001_test';

        set @v =
        N'(
          select stuff((
          select cast('' union all select * from '' as nvarchar(max)) + quotename(''CEE_097_001'')
          from information_schema.tables
          where table_name like @BaseTableName))
        )';

        set @s = 'DROP VIEW ' + @View;
        EXEC (@s);

        set @c = N'CREATE VIEW @View AS ' + @v;
        EXEC Sp_executesql @c, N'@View varchar(100), @BaseTableName varchar(100)', @View, @BaseTableName;

输出：
过程或函数'spCreateView2015'需要参数'@BaseTableName'，这是未提供的。

Database附近缺少引号，设置动态变量@v时应添加引号。应该是这样的：

CREATE PROCEDURE spCreateView2015 
@BaseTableName varchar(100) = 'Table_XXX_15%',
@View varchar(100) = 'View_XXX_2015'
AS  
BEGIN  
    SET NOCOUNT ON;

            declare @v nvarchar(max) 
            set @v =
            '(
              select stuff((
              select cast('' union all select * from '' as nvarchar(max)) + quotename(''Database'')
              from information_schema.tables
              where name like @BaseTableName))
            );'

        declare @s nvarchar(max) = 'DROP VIEW ' + @View;
        EXEC Sp_executesql @s, N'@BaseTableName varchar(100), @View varchar(100)', @BaseTableName, @View

        declare @c nvarchar(max) = 'CREATE VIEW ' + @View + ' AS ' + @v;
        EXEC Sp_executesql @c, N'@BaseTableName varchar(100), @View varchar(100)', @BaseTableName, @View           

END

创建基于前缀来联合特定表的视图
