问题 I created a table using select with a union , as follows: create table tableC as select column1, column2 from tableA union all select column1, column2 from tableB The resulting table ( tableC ) has inherited none of the constraints from tableA or tableB . Why weren't the constraints copied to the new table? 回答1: Using select ... as ... to create a table never copies constraints. If you want the new table to inherit constraints from the original tables, you must create the new constraints

问题 My system write some data to a SQL Server DB (2008), extracts it later and processes it some more, before writing it to an Oracle (10g) DB. I've wrapped my SQL Server interactions in a TransactionScope but when I try the same think with my Oracle interactions I get a `TranactionAbortedException - "The transaction has aborted". Remove the TransactionScope, and everything works OK. I could always revert back to manually managing my own transactions, but I'm hoping there is a simple solution.

It keeps saying ORA-01407: cannot update ("SCHEMA1".

问题 There are a lot of inactive connection in my oracle server. I retrieve SQL text from those inactive. The SQL test is SELECT PARAMETER, VALUE FROM SYS.NLS_DATABASE_PARAMETERS WHERE PARAMETER IN ('NLS_CHARACTERSET', 'NLS_NCHAR_CHARACTERSET') but I never use the SQL statement in my system, and do not know why the statement run automatically without closing automatically. 回答1: Is there a problem? In most systems, most sessions are inactive the vast majority of the time. An inactive session merely

问题 Similar question to: Strange problem with JDBC, select returns null but people didn't ask for this. My code: public int myMethod(String day) throws SQLException{ String sql = "Select count(*) from MyTable WHERE someColumn = " + day; Connection connection = ConnFactory.get(); PreparedStatement prepareStatement = null; ResultSet resultSet = null; int ret = -1; try{ prepareStatement = connection.prepareStatement(sql); resultSet = prepareStatement.executeQuery(sql); if(resultSet.next()){ ret =

问题 I have several SQL files that I want to import. An example: CREATE TABLE BB_Department ( idDepartment number(2) , DeptName varchar2(25) , DeptDesc varchar2(100) , DeptImage varchar2(25) , CONSTRAINT dept_id_pk PRIMARY KEY(idDepartment) ); insert into bb_department values(1,'Coffee','Many types of coffee beans','coffee.gif'); When importing this with http://localhost:8080/apex I continually receive the 'invalid character' error. It seems that one can only run ONE SQL statement at a time. The

问题 I have a web application that uses JAXB 2. When deployed on an Oracle 10g Application Server, I get errors as soon as I try to marshal an XML file. It turns out that Oracle includes JAXB 1 in a jar sneakily renamed "xml.jar". How I can force my webapp to use the version of the jaxb jars that I deployed in WEB-INF/lib over that which Oracle has forced into the classpath, ideally through configuration rather than having to mess about with classloaders in my code? 回答1: I assume you use the

问题 Which table contains detailed information(For example the table the foreign key is referring to) about the constraints? The tables 'all_cons_columns' , 'all_constraints' contains only the name of the constraints which isn't very helpful. I am currently using dbms_metadata.get_ddl() but it doesn't work on all the databases.
