Zhang Yon · Journal of Yangtze River Scientific Research Institute · 2001
For implementing universal dynamic multi table query under the PowerBuilder condition,three aspects,i.e.,the data base struction design,the interface design and multi table query method,are discussed in the paper.The method can meet the retriaval query requirement for hydraulic planning,design items through arbitrary composite ways.The train of trought for getting suitable single tables from compasite table by use of the data moving between two buffer regions is introduced.
