There are still some omissions. The experiment is not very rigorous in theory! 1. transaction isolation level settings Oracle has two transaction isolation levels: connection. transaction_read_committed (Read committed) and connection. transaction_serializable (Serial read ). If an error occurs when setting the isolation level, the following exception is thrown: Java. SQL. sqlexception: Only read_committed and serializable are valid transaction processing levels.

One: From the dBASE file, import data into the SQL database, very simple, directly using the following statement: /*===================================================================*/ --If the table that accepts the data import already exists INSERT INTO table SELECT * FROM OpenRowset (' MICROSOFT.

Oracle users01.dbf is getting bigger and bigger. After oracle deletes data, the tablespace is not released, and the dbf file is getting bigger and bigger. You can use: SQL> ALTER DATABASE DATAFILE 'C: \ oracle \ product \ 10.2.0 \ oradata \ orcl \ USERS01.DBF 'resize 1G; to shrink the tablespace, if an error is reported: "ORA-03297: file contains data not used by

Currently, most C # databases are connected to SQL server. However, I am not familiar with the connection and operations of some old database files.This problem occurs today. You need to operate the DBF file database generated by FOXPRO.I have been investigating CSDN for a long time, and most of the problems have not been well resolved to these operations.After my experiment, you can use ODBC to connect to it.The following code is used.It is very simp

Problem description: If you accidentally delete the dbf file of the Oracle database, an error is prompted when you start or close the database.
