1. Set Date format
Alter system set nls_date_format= ' Yyyy-mm-dd hh24:mi:ss ' scope=spfile;
Select To_char (sysdate, ' Yyyy-mm-dd hh24:mi:ss ') from dual;
2. Add Supplemental Log
If the database needs to use Logminer, it should be added, only after this log is added to capture DML
ALTER DATABASE ADD Supplemental LOG DATA (PRIMARY KEY, UNIQUE INDEX) COLUMNS;
3. Open Archive

The NFA is converted to a DFA, and a subset construction (subset construction) algorithm is used. The process of the algorithm is similar to the NFA matching process mentioned in section 3.1 of the C # lexical Analyzer (iii) regular expression. In the NFA matching process, use is a state of

Calculator is a lot of programming beginners have done, starting from the simplest console program, input values, input operators, and then enter a value, to get a result. The interface is basically modeled on the Windows operating system calculator, through the button input values and operators, and then give the results of the operation. Can you directly enter an expression, or you can calculate several expressions, or select a part of an expression to calculate, if the input error can indicat

Today, we will introduce how to perform one-step debugging through the debugging function of the query analyzer. This is also a very practical technique. Q: How can I perform one-step debugging through the debugging function of the query analyzer? A: The specific steps are as follows: 1. Set the server [authentication] attribute to [hybrid mode] (window and SQL identity)
Today, we will introduce how to perf
