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

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 attcnt=1 rno=24 op=6 padlen=2 sessionid=256008,2 len=64 odc_stat=0x0000 (0x0000) loh_status: 0x0 (0x00000000) objid=608002166 ptnid=608002166 pageno=801 offset=32 status=0x2000 (0x2 000 (XSTAT_EXTABLE)) cid=0 indid=0 old ts=0x0000 0x000017f8 new ts=0x0000 0x000017f9 data rnum 0 ptr=(256008,13) INSIND (256008,25) sessionid=256008,2 attcnt=1 rno=25 op=6 padlen=2 sessionid=256008,2 len=64 odc_stat=0x0000 (0x0000) loh_status: 0x0 (0x00000000) objid=608002166 ptnid=608002166 pageno=801 offset=49 status=0x2000 (0x2 000 (XSTAT_EXTABLE)) cid=0 indid=0 old ts=0x0000 0x000017f9 new ts=0x0000 0x000017fa data rnum 1 ptr=(256008,15) INSIND (256008,26) sessionid=256008,2 attcnt=1 rno=26 op=6 padlen=2 sessionid=256008,2 len=64 odc_stat=0x0000 (0x0000) loh_status: 0x0 (0x00000000) objid=608002166 ptnid=608002166 pageno=801 offset=66 status=0x2000 (0x2 000 (XSTAT_EXTABLE)) cid=0 indid=0 old ts=0x0000 0x000017fa new ts=0x0000 0x000017fb data rnum 2 ptr=(256008,17) INSIND (256008,27) sessionid=256008,2 attcnt=1 rno=27 op=6 padlen=2 sessionid=256008,2 len=64 odc_stat=0x0000 (0x0000) loh_status: 0x0 (0x00000000) objid=608002166 ptnid=608002166 pageno=801 offset=83 status=0x2000 (0x2 000 (XSTAT_EXTABLE)) cid=0 indid=0 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：
