Problems solved by technology

[0003] In the existing technology, the optimized fuzzy query in the development of large-scale projects generally requires third-party software to be implemented. The third-party software is not only cumbersome to install, but also has high maintenance costs.
But for the optimized fuzzy query of small and medium-sized projects, if third-party software is used, the project cost will be high, and if third-party software is not used, the query time will be very slow

Embodiment approach

[0051] Yet another embodiment of the present invention, this embodiment also includes:

[0052] Each keyword in the intermediate key is also correspondingly provided with an update time, which is the last fuzzy query time of the keyword in the original database;

[0053] Set an effective time in the middle key;

[0054] If the difference between the current time of the query keyword and the update time corresponding to the keyword in the intermediate key is less than the valid time, execute steps S3-S4; otherwise, execute step S5.

[0055] In this embodiment, if the difference is greater than the effective time, the keyword is fuzzy searched in the original database, the current time is set as the update time, and then the corresponding query result ID, the keyword and the update time in the original database are recorded Go to the table item corresponding to the intermediate data table, and obtain the data information corresponding to the query result ID in the original data...

Abstract

The invention discloses a query method and a data query system; the method comprises the following steps: building an intermediate key at least comprising a keyword and a query result ID corresponding to with the keyword, wherein the query result ID refers to the ID corresponding to the query result outputted by using the keyword to carry out fuzzy query in an original database; receiving a user inputted keyword; accurately searching the keyword in the intermediate key; obtaining the query information corresponding to the query result ID from the original database according to the query result ID matched with the keyword in the intermediate key if the keyword is successfully matched; if the keyword is not matched, using the keyword to carry out fuzzy query in the original database and outputting the query information, thus reducing fuzzy query time, and improving fuzzy query efficiency.

Description

technical field [0001] The invention relates to the field of data query, in particular to a query method and a data query system. Background technique [0002] Fuzzy query is the most commonly used search tool for computers to find information, through which you can find the desired information. Fuzzy query refers to the way to find relevant data by using some parameters, usually using keywords to search fuzzy. The so-called keywords are the characters contained in the registration information, such as name query, only specifying a certain part of the name, such as a surname or a name or a combination of them, can find related data. [0003] In the prior art, the optimized fuzzy query in large-scale project development generally requires third-party software to be implemented, and the third-party software is not only cumbersome to install, but also has high maintenance costs. But for the optimized fuzzy query of small and medium-sized projects, if third-party software is u...
