sybase中给表增加和删除字段时内部处理过程分析
分析一下给表增加字段时sybase数据库的内部处理过程。
表原来的结构：
create table t(id int, col1 varchar(30))
向表中插入数据：
insert into t
select 1,'a'
go
insert into t
select 1,'a'
go
insert into t
select 2,'b'
go
insert into t
select 3,'c'
go
测试表t的object_id是：
1> select object_id('t')
2> go
-----------
608002166
利用dbcc log分析数据库的日志，可以看出上面的四条insert语句对应了四个单独的事务。因为sybase中默认是隐式提交的。
四条记录的页号和偏移分别是：
row1. pageno=801 offset=32
row2. pageno=801 offset=44
row3. pageno=801 offset=56
row4. pageno=801 offset=68

接着，向表中添加一个identity字段。
alter table t add col2 int identity not null
go
再利用dbcc log分析日志，我们可以看出在这四行数据上面发生了延迟更新（op=6,INSID在日志类型中是延迟更新的意思！）。
每行数据的页号和偏移变成了：
row1. pageno=801 offset=32
row2. pageno=801 offset=49
row3. pageno=801 offset=66
row4. pageno=801 offset=83
INSIND (256008,24) sessionid=256008,2

old ts=0x0000 0x000017fb new ts=0x0000 0x000017fc
data rnum 3 ptr=(256008,19)
比较一下前后的各行的偏移量。我们发现：第一行没有移动，第二行向下移动了5（49-44）字节，第三行向下移动了10字节，第四行向下移动了15字节（83-68）。也就是说，每行增加了5个字节的数据。5个字节是因为：int类型占用4个字节再加一个字节的长度。
关于alter table add语法方面的
在向表添加列时是不能够添加not null 列的。错误如下所示：
1> alter table t add col4 char(30) not null
2> go
Msg 4997, Level 16, State 1:
Server 'SYB_NFJD_TEST', Line 1:
ALTER TABLE 't' failed. Default clause is required in order to add non-NULL
column 'col4'.
1> alter table t add col4 int not null
2> go
Msg 4997, Level 16, State 1:
Server 'SYB_NFJD_TEST', Line 1:
ALTER TABLE 't' failed. Default clause is required in order to add non-NULL
column 'col4'.
1>
1. 只能添加为空的字段。
2. 但是，本文前面的向表添加identity类型的int 非空字段却可以。alter table t add col2 int identity not null却可以。
3. 这似乎和SQL标准中的不太一致。
4. 分析page：801页面上的数据。发现最后添加的identity列居然是作为可变长字段进行存储的。字段col即使被定义为非空，但是物理存储上却是作为可变长存储的。因为是varchar类型。
注意： 后来我通过试验发现有一种例外情况。就是新增一个非空列的时候对这列指定默认值，就可以成功增加这列。
比如：alter table test add COLC char(1) default "0" not null
这条语句就能够成功执行！
删除表上的字段的时候报错：
1> alter table t drop col2
2> go
Msg 11052, Level 16, State 1:
Server 'SYB_NFJD_TEST', Line 1:
The 'select into' database option is not enabled for database 'testdb'. ALTER
TABLE with data copy cannot be done. Set the 'select into' database option and
re-run.
1>
报错的原因是表t所在的数据库testdb没有打开select into buklcopy选项。
打开testdb的select into/bulkcopy/pllsort 选项
1> use master
2> go
1> sp_dboption testdb,'select into',true
2> go
Database option 'select into/bulkcopy/pllsort' turned ON for database 'testdb'.
Running CHECKPOINT on database 'testdb' for option 'select
into/bulkcopy/pllsort' to take effect.
(return status = 0)
再次执行删除列的操作，可以执行成功！
1> use testdb
2> go
1> alter table t drop col2
2> go
(4 rows affected)
删除完col2之后，再次分析一下dbcc log的结果。
发现背后进行的操作有三步：
第一：删除表t在systabstats上的统计信息并重建；
第二：删除在系统表sysstatistics,sysobjects,syscolumns,sysindexes,syspartitions上对应记录的索引然后重建；
第三：更新在系统表sysstatistics,sysobjects,syscolumns,sysindexes,syspartitions上对应记录的信息。
删除表上的列的过程的日志信息，如下：

有兴趣的可以自己分析一下。
自己先补充一下。
如果数据库没有打开select into选项的时候，drop column都会报错误：
Msg 11052, Level 16, State 1: Server 'TEST', Line 1: The 'select into' database option is not enabled for database 'escourt5'. ALTER TABLE with data copy cannot be done. Set the 'select into' database option and re-run 。
注意：不能添加非空列（除了第一个identity列）。 添加一列的时候，指定为非空并且有默认值的话，也报错：
1> alter table test add COLE char(1) default "0"
2> go
Msg 11052, Level 16, State 1: Server 'TEST', Line 1: The 'select into' database option is not enabled for database 'escourt5'. ALTER TABLE with data copy cannot be done. Set the 'select into' database option and re-run.
有空总结一下。 为什么会进行data copy。
