Chronological book inquiry method and device

Abstract

The present invention discloses a query method of a chronological book, including the following steps: S1, whether the definition of a query field is included in the metadata of the chronological bookis decided according to the submitted query field, if so, S3 is then executed, and if not, S2 is then executed; S2, the query field is defined in the metadata and S3 is executed; S3, the query fieldis extracted from the metadata and displayed; S4, query conditions are set by adoptive users based on the query field, and a query plan is generated based on query conditions, and the query plan is saved; S5, a search is conducted in the chronological book database according to the query conditions. The present invention can set query conditions flexibly and utilize the query conditions repeatedly.

Description

technical field

[0001] The invention relates to the field of computer data query, in particular to a query method for a chronological book and a device for inquiring a chronological book. Background technique

[0002] The list is a display report of business document data. At present, the query of the list is similar to the query of the database, that is, the process of obtaining the query results that meet the query conditions by setting the query conditions. During the query process of the list , the query field is the key factor in defining the query conditions.

[0003] However, in the prior art, the query field of the list is usually fixedly set in the source program code, or stored in a system file (such as a TXT file), and the setting is usually completed before the product leaves the factory. In this case, when the user sets the query conditions, the query fields that can be used are fixed, that is, initially set by the system. In the process of setting query condi...

[0050] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] refer to figure 1 , which shows a flow chart of an embodiment of a timebook query method according to the present invention, which may specifically include the following steps:

[0052] Step 101. According to the submitted query field, it is judged whether the metadata of the list includes the definition of the query field, if yes, execute step 103; if not, execute step 102;

[0053] Step 102, define the query field in the metadata, and execute step 103;

[0054] Step 103, extracting the query field from the metadata and displaying it;

[0055] Step 104, receiving the query condition set by the user for the query field, generating a query scheme according to the query condition, and saving the query scheme;
