Data retrieval condition setting method
First Claim
1. A method of setting a data retrieval condition for retrieving data from a database, said method comprising the steps of:
- displaying unit retrieval conditions separated by logic symbols which logically associate said unit retrieval conditions with each other, on a display device;
receiving specific information for specifying one of said logic symbols based on which priority-given retrieval is executed;
highlighting with color or display density the logic symbol indicated by said received specific information and the unit retrieval conditions displayed adjacent to said logic symbol from other unit retrieval conditions or other logic symbols; and
logically building said data retrieval condition based on said unit retrieval conditions, said logic symbols and said specific information.

Abstract
When an operator inputs a unit retrieval condition and a logic symbol, a condition input section stores them in a condition storage section. A condition display section displays them alternately one after another on a display device. When the operator inputs specific information for specifying the logic symbol among the displayed logic symbols for which a priority-given retrieval based on the unit retrieval conditions displayed ahead and behind the logic symbol should be performed, a condition operating section raises the priority order of the logic symbol in the condition storage section in accordance with the specific information. The condition display section performs a specific distinguishing display on the logic symbol, indicated by the accepted specific information, and the unit retrieval conditions displayed ahead and behind the logic symbol to distinguish them from other unit retrieval conditions and logic symbols. When the operator operates an execution key, a condition building section logically builds a data retrieval condition for retrieving data from a database, from the input unit retrieval conditions, the logic symbols and the specific information.

7. A method of setting a data retrieval condition for retrieving data from a database, said method comprising the steps of:
-
alternately displaying unit retrieval conditions and logic symbols for logically associating said unit retrieval conditions with each other on a display device, with first letters of each of said unit retrieval conditions and logic symbols put side by side, said input unit retrieval conditions and logic symbols are displayed line after line on said display device, with display positions of heads of said input unit retrieval conditions and logic symbols being aligned in a same column; and receiving specific information for specifying ones of said logic symbols based on which priority-given retrieval is executed; shifting display positions of all of said logic symbol which are indicated by said received specific information and unit retrieval conditions adjacent to said indicated logic symbols on said display device, wherein a display column of heads of said unit retrieval condition and said logic symbol which are subjected to said distinctive display is shifted by a given amount; and logically building said data retrieval condition based on said unit retrieval conditions, said logic symbols and said specific information.
