Oracle - cursor using dbms_utility.exec_ddl_statement not executing properly

由 余生长醉 提交于 2019-12-08 07:33:01
问题 I have a requirement to run a SP across multiple DBs at the same time and one part of it is to eliminate some duplicate records from each DB. Now since the SP can be run multiple times i've included a backup table and and what's needed to truncate and drop it in case the SP is run twice in a row. Now, since i'm creating tables via DBLINK i've researched that i need to use dbms_utility.exec_ddl_statement - but in this case even though the procedure executes, the truncate and drop queries seem

Convert mysql database to Oracle

由 北战南征 提交于 2019-12-08 06:51:42
问题 I want to convert my MySQL database to Oracle. I read this. I tried Oracle SQL Developer and watched this as well. I downloaded the oracle developer from Oracle. But there isn't any item called "Migrations" or "Repository" in that tool. I use MySQL 5.5 and oracle 10 g servers. How do I convert a MySQL database to Oracle? Any working code or useful link would be appreciated. I am familiar with MySQL, but an absolute beginner on Oracle databases. 回答1: The download link you showed for Oracle SQL

exporting db objects for version control

由 久未见 提交于 2019-12-08 03:40:09
问题 We are implementing version control for our project. As part of this we need to check in all DB objects. We have tables, procedures, functions, packages, view and materialized view. Problem is there are many objects and we need to put source code file wise. e.g. There are tables T1, T2, T3 and we need files Table_T1.txt which will have T1 definition ( columns definition, indexes for the table and grants) and so on for all objects. I m aware of metadata tables such as DBA_VIEWS , dba_source

SQL Server: How to generate object scripts without DMO/SMO?

由 孤者浪人 提交于 2019-12-08 02:17:08

( EDIT : It looks as if SMO is actually redistributable as of today.) Is there any source code that converts SELECTs from system

MySQL to PostgreSQL table create conversion - charset and collation

由 耗尽温柔 提交于 2019-12-07 15:21:27
I want to migrate from MySQL to PostgreSQL.My query for create table is like this. CREATE TABLE IF NOT EXISTS conftype ( CType char(1) NOT NULL, RegEx varchar(300) default NULL, ErrStr varchar(300) default NULL, Min integer default NULL, Max integer default NULL, PRIMARY KEY (CType) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COLLATE=latin1_bin; What is the converted form of this query. I am confused with DEFAULT CHARSET=latin1 COLLATE=latin1_bin part. How can I convert this part? That one would mean that the table uses only latin-1 (iso-8859-1) character set and latin-1 binary sorting order. In

Renaming multiple columns in PostgreSQL

由 亡梦爱人 提交于 2019-12-07 06:41:11
问题 My table has a bunch of columns in the following format: _settingA _settingB _settingB And I want to rename them simply to add a prefix as follows: _1_settingA _1_settingB _1_settingC What is the quickest / most efficient way to achieve this? EDIT: I should add that I have a lot more than three columns to rename in this way. If I had just three, I'd just do it manually one by one. And thanks for the downvote whoever you are. 回答1: There's no single command aproach. Obviously you could type

Free/OSS Data model diagram generator from DDL

由 断了今生、忘了曾经 提交于 2019-12-06 17:01:34
I am looking for some free/oss to reverse engineer from DDL a data model diagram. My database is Oracle if that matters. Do any exist? http://schemaspy.sourceforge.net/ SQL Power architect has a GPL version (though it looks like they are releasing an 'Enterprise' edition soon) There is also FabForce's DBDesigner , though it is more geared to MySQL (but has some Oracle capability) You could also look at sql-developer and data-modeler from Oracle. both are free http://www.oracle.com/technetwork/developer-tools/datamodeler/downloads/datamodeler-087275.html 来源： https://stackoverflow.com/questions
