Sql server SQL Server不支持'；t禁用索引
我有一个测试数据库，我正试图调整某列的大小和索引。 表中只有几行。 让我们不要说话，让我们展示代码Sql server SQL Server不支持'；t禁用索引,sql-server,resize,indexing,Sql Server,Resize,Indexing,我有一个测试数据库，我正试图调整某列的大小和索引。 表中只有几行。 让我们不要说话，让我们展示代码 Create Table Country (ID INT PRIMARY KEY IDENTITY, NAME VARCHAR(48),ENEMY VARCHAR(32),AMOUNT INT); CREATE NONCLUSTERED INDEX IDX_COUNTRY_NAME ON Country(NAME); 我添加一些行。稍后使用sql语句调整列的大小，如下所示： ALTER IND
Create Table Country (ID INT PRIMARY KEY IDENTITY, NAME VARCHAR(48),ENEMY VARCHAR(32),AMOUNT INT);
CREATE NONCLUSTERED INDEX IDX_COUNTRY_NAME ON Country(NAME);
ALTER INDEX IDX_COUNTRY_NAME ON Country disable;
alter table COUNTRY alter column NAME VARCHAR(40);
ALTER INDEX IDX_COUNTRY_NAME ON Country rebuild;`
java.sql.BatchUpdateException: The index 'IDX_COUNTRY_NAME' is dependent on column 'NAME'.

我希望避免删除索引，因为我不知道将来是否存在指向随机索引的脚本，并且在重新加载它们时会遇到问题。 我正在使用SQLServer2008 我试了很多方法来完成这件事。唯一的希望是使用drop，但正如我之前所说，我宁愿不使用它 编辑 这些只是示例sql，我知道我更新了哪个表和列。为了找到它，我使用sys.index、sys.index\u列，并通过object\u id将它们连接起来。这很好，因为我打印了所有结果，并且与预期的一样。从on ALTER表的ALTER COLUMN部分： 修改后的列不能是以下任一列： [……]
- 在索引中使用，除非列是varchar、nvarchar或varbinary数据类型，否则数据类型不会更改，新大小等于或大于旧大小，并且索引不是主键约束的结果
varchar（48）varchar（40）- 在索引中使用，除非列是varchar、nvarchar或varbinary数据类型，否则数据类型不会更改，新大小等于或大于旧大小，并且索引不是主键约束的结果
