DB2分区表如何区分索引是分区索引还是非分区索引

问题描述 : 经常有人问,我分区表里的索引到底是分区索引还是非分区索引? 因为是否是分区索引涉及到detach分区的时候是否会耗费大量的时间做异步索引清理:如果是非分区索引,则异步索引清理需要大量时间。 总体结论 : --对于唯一索引或者主健,如果包含了分区健,则默认是分区索引;如果不包含分区健,则默认是非分区索引。 --对于非唯一索引,默认都是分区索引。 测试过程 DB2版本为10.5 $ db2 "create table p1 (col1 int not null, col2 int not null, col3 int not null) partition by range(col2)(partition part1 starting 1 ending 5, partition part2 starting 6 ending 10, partition part3 starting 11 ending 15)" 1. 唯一索引 $ db2 "create unique index u_idx1 on p1 (col1)" $ db2 "create unique index u_idx1_2 on p1 (col1,col2)" $ db2 "create unique index u_idx1_3 on p1 (col1,col3)" $ db2look -d

下载kettle 下载MySQL和DB2的驱动,解压驱动到文件夹lib下(驱动网上都可以找到) 双击运行kettle,时间会有点长,稍等1,2分钟左右 双击运行kettle,时间会有点长,稍等1,2分钟左右 进入kettle界面,转换输入表输入(按住‘表输入’往右边拖) 双击右边的‘表输入’进入配置数据库信息,点击新建,类型选择MySQL数据库 为了防止中文乱码,指定字符集characterEncoding utf8, 在kettle的启动文件添加字符集,即在 Spoon.bat 文件中添加 “-Dfile.encoding=UTF-8” 配置好后点击‘测试‘,如下图显示是为正常 点击获取SQL查询语句,选择对应的表之后(每次只能指定一张表),方可预览表中数据 同上,“表输入”配置完毕,接下来可配置“插入/更新”,输出->插入/更新(按住‘插入/更新’往右边拖),按住shift点击‘表输入‘再点击’插入/更新‘建立联系 双击‘插入/更新‘进行数据库配置,在’选项‘中配置utf8字符集(同上) 点击测试 选择‘目标模式‘、’目标表‘(每次只能指定一张表),点击’获取字段‘、’获取和更新字段‘是mysql表字段与之匹配 增量转换 首先获取某个字段的最大值,然后把这个值作为下个‘表输入’的条件 SELECT coalesce(max(字段名),0) maxId FROM 库名.表名

Sql Cleanup script, delete from one table that's not in the other

半腔热情 提交于 2020-01-17 14:05:11
问题 We wrote a cleanup script in SQL(DB2) as400 to do cleanup of tables. ps we are fixing the processes that is causing the data issues. The SQL : DELETE FROM p6prodpf A WHERE (0 = (SELECT COUNT(*) FROM P6OPIPF B WHERE B.OPIID = A.OPIID)) Its simple code to check if theres a record in p6prodpf that has no record in P6OPIPF then delete the record in p6prodpf . My problem that I am facing is that there's instances where the p6prodpf is being deleted even if theres a record in P6OPIPF . Is there a

DB2 keeping n columns in sync between two tables

夙愿已清 提交于 2020-01-17 13:09:06
问题 I have a two tables (actually sets of tables) which may need to be kept in sync (The first set of tables I need all the data replicated to the second set where this data will be a subset). If why matters (perhaps because it is obviously not very good form having replicated data) see (very bottom of this other question under the ' PS ' section): DB2 update and insert trigger, references a lot of fields can I use * to shorten them (in iSeries but might not matter) To do this I'm placing insert,

Quantity of transaction logs used per application/connection in DB2

白昼怎懂夜的黑 提交于 2020-01-17 12:38:45
问题 I would like to know the quantity of logs used (active logs) by each connection in the database. I know how to retrieve the quantity of active logs for the database, but not for each application. Knowing the quantity of active logs in the database helps me to identify if a log-full condition is approaching. However, I want to know which application is approaching to this condition of log-full. For this reason, I need to know how much log is used by each transaction (each application), but I
