When exporting data for a oracle11.2.0.2 server, the "EXP-00003: storage definition for segment (0,0)" error was reported. The initial analysis is due to the fact that the data table is empty and the table causes the problem.An empty table cannot be exported when Oracle 11G is exported with exportThere is a new feature in 11GR2 that does not allocate segment when the table has no data to save spaceWorkaroun

Strict mode (strict mode), all variable definitions need to use the var keyword. If you do not use strict mode, then when the JS program to an undefined variable to assign a value, the program will be in the JS global object to create a name and the same variable property, that is, create a new global variable. This practice will bring a lot of problems (for example, a number of JS program to produce global variable pollution, etc.), to the maintenance of the later bring no small trouble, so in
