How to write DB2 DDL & DML audit logs as System Application Logs?

阅读更多关于 How to write DB2 DDL & DML audit logs as System Application Logs?

问题 I am using DB2 LUW in a windows machine. I want to get the logs for DDL & DML queries used in the database. The default logs(for example S000001.LOG) contains 'null' and not in a readable format. So I enabled auditing and extracted the archived audit logs into .del files. But the audit log extraction creates .del like this: execute.del "2019-09-05-01.19.44.443001","EXECUTE","STATEMENT",13,0,"TEST2","Administrator","ADMINISTRATOR","ADMINISTRATOR",,,"*LOCAL.DB2.190904193137","db2bp.exe",,,,,,,,

Is using a SELECT inside a pipelined PL/SQL table function allowed?

阅读更多关于 Is using a SELECT inside a pipelined PL/SQL table function allowed?

问题 The docs for pipelined functions say that DML is not allowed when they are used in a SQL statement (typically a SELECT ), and in most examples the pipelined functions are used for data generation or transformation (accepting a custor as parameter), but not issuing any DML statements. Now, technically, it is possible to use SELECTs without any error from Oracle (ORA 14551 will not occur). However, I have experiences reproducible strange behavior of the select; even though PRAGMA AUTONOMOUS

郑昀创建于2015/12/2 最后更新于2015/12/2 关键词：数据库，MySQL，自动化运维，AutoDDL，刷库，帐号授权，审核，回滚 iDB 是刘勤红部门推出的数据库自动化运维平台，它其实已经断断续续开发了几个月了，线上也跑了一段时间，最近又发布了新版本。版本迭代的主力是王晓华同学，李世杰也参与了一部分开发工作，曹富志和张永奎是需求方。 iDB 的主要目的是解决绝大部分重复、复杂的数据库运维工作，满足业务对数据库信息查询和快速变更需求，借此提升研发效率，保证数据库操作符合审计要求，有可追溯的变更和审核日志。 0x00，数据库自动化运维什么？别人家是怎么玩的？当数据库越来越多时，比如按业务垂直分库了，10个，50个，100个…… 当数据库关系越来越复杂时，比如 Cobar 水平拆库，从库分组，级联从库，合并库，比如某些索引要求只建在特定从库上…… DBA 的日常管理，手速再快，也不得不希望有系统来帮忙，毕竟数据库拓扑建立起来后，很多操作都可以自动化完成。举个例子，工程上线前要开数据库访问帐号和权限。没有平台的话，那就得 DBA 一个一个去建，写库是 M 打头的帐号，读库是 S 打头的帐号，密码强度还得高。有了平台之后，DBA 只需要审核研发人员提的需求即可，系统自动化生成帐号密码，然后发邮件给申请人，或者将密码生成对称加密后的密文展示给申请人。再比如

问题 I have a table that contains mamy columns and I want to update the one or few columns of the row without effecting remaining columns I can write query: update table as t set t.a=:a set t.b=:b where t.id=1 But seen I dont know which columns will be selected to update, and I think it is not a good idea to write every query for every scenarios.

Combine stored procedure and query in T-SQL

阅读更多关于 Combine stored procedure and query in T-SQL

问题 How do I combine executing of a stored procedure and using its result or parameters in a regular SQL query? For example I would like to do something like the following: -- passing result of SELECT to SP SELECT a, b FROM t EXEC my_sp a, b -- passing result of SP to INSERT INSERT INTO t EXEC my_sp a, b etc. 回答1: no, you need to use a temp table create table #results (col1 int, col2 varchar(5) ...) INSERT INTO #results EXEC YourProcedure @parma... then you can join to it SELECT * FROM YourTable

I am trying to extract the first row I get after ordering the result by i_version_id . If I do not use TOP(2) , my query works as expected ans returns all results sorted by i_version_id. But when I add the TOP(2) (as shown below), it says that there is a syntax error near distinct . Please let me know what I am doing wrong. SELECT TOP(2) distinct(i_version_id) FROM [PaymentGateway_2006].[dbo].[merchant] WHERE dt_updated_datetime > '2013-11-11' GROUP BY i_version_id ORDER BY i_version_id; D Stanley If you're only getting the TOP 1 then distinct is irrelevant. It's also irrelevant since grouping
