Runstats:收集统计信息,为DB2优化器提供最佳路径选择。 runstats命令只能针对单表执行。命令格式:db2 runstats on table schema.tabname runstats选项默认为allow write access,DB2在runstats的表上加IN锁,可以读取和修改表数据。指定allow read access会在runstats的表上加S锁,只能读取数据,无法修改。 runstats统计结果存在系统表中,syscat.tables保存表统计信息,syscat.indexes保存索引统计信息。 可以查看syscat.tables的stat_time字段,表是否有收集统计信息。db2 "select substr(tabname,1,20) as tabname,stats_time from syscat.tables where stats_time is null" 另外可以使用db2look的mimc选项抽取统计数据。这样可以在测试机器上模拟生产环境的数据,进行测试。 db2look -d sample -m > db2look_stat.out --------------------------------------------------------------------------------- Reorgchk:重组检查

Difference between CLOB and BLOB from DB2 and Oracle Perspective?

六月ゝ 毕业季﹏ 提交于 2019-12-03 00:34:57
问题 I have been pretty much fascinated by these two data types. According to Oracle Docs , they are presented as follows : BLOB : Variable-length binary large object string that can be up to 2GB (2,147,483,647) long. Primarily intended to hold non-traditional data, such as voice or mixed media. BLOB strings are not associated with a character set, as with FOR BIT DATA strings. CLOB : Variable-length character large object string that can be up to 2GB (2,147,483,647) long. A CLOB can store single

DB2浮点数转换成字符串

1.比较通用的方法: SELECT rtrim(cast(111.987 as char(20))) from sysibm.SYSDUMMY1; 在db2 v8,db2 v9.1,db2 v10.1 db2 v10.5都可以用. 注:这种方法无法格式化字符串。 2.db2 v9.1及以后的版本: select trim(replace(strip(replace(char(cast(12.9 as decimal(8,3))),'0.','#'),L,'0'),'#','0.')) from sysibm.sysdummy1; 注:这种方法是在网上找的,可以对数据进行格式化。但是无法处理负数。 如图 这个结果不是我想要的,正确的应该是:-12.900。 所以对上述方法进行小的调整。 select case when tmp.amnum<0 then '-' || trim(replace(strip(replace(char(tmp.amnum*-1),'0.','#'),L,'0'),'#','0.')) else trim(replace(strip(replace(char(tmp.amnum),'0.','#'),L,'0'),'#','0.')) END from (select cast(-90123.459 as decimal(20,2)) as amnum

DB2复制表结构及数据

匿名 (未验证) 提交于 2019-12-02 23:52:01
在DB2数据库中,复制已经存在的表的结构及其数据。我们采用两步走方式:第一步先复制表结构,第二部拷贝数据。 第一步:复制表结构 方法一: Create table test_Rate as (select * from t_Rate) Definition only; --test_Rate是新表,t_Rate是老表 方法二: Create table test_Rate like t_Rate; --test_Rate 是新表,t_Rate是老表 说明: 上述方式创建的新表不复制老表的主键,约束,索引,数据。且创建的新表放在用户的临时表空间中。 /*----查询新表test_Rate的主键,表空间----*/ select keycolumns,keyindexid,tbspace from syscat.tables where tabname='TEST_RATE' --keycolumns:表示有几个字段组成联合主键,keyindexid:等于0表示没有主键 /*----查询新表test_Rate的索引----*/ select * from syscat.indexes where tabname='TEST_RATE'; --上述查询有记录表示表有索引,反之没有 /*----查询新表test_Rate的记录条数----*/ select count(1) from
