The invention discloses a database query field generation method and apparatus, which relates to the technical field of databases and is invented for solving the problem that a user cannot freely define query fields. The method comprises the steps of receiving a field definition rule established based on a basic data structure, wherein the field definition rule contains one or more query fields in the basic data structure and an operational relationship among the one or more query fields; verifying whether the field definition rule conforms to a query rule of the basic data structure or not; and if the field definition rule conforms to the query rule of the basic data structure, generating a relationship table corresponding to the field definition rule in a database, generating self-defined query fields corresponding to the field definition rule, and storing the self-defined query fields. The method and the apparatus are mainly applied to a process of performing field self-definition on the relational database.

The invention discloses a video concentrating method and device, a computer readable storage medium and a computer apparatus. The video concentrating method comprises the following steps: for any video frame of a set video, determining preset bit information corresponding to the any video frame, wherein the preset bit information corresponding to the any video frame is used for characterizing information of a preset bit to which a camera operates when the any video frame is shot; if determining that the any video frame includes a set moving object, determining the any video frame as a key frame; and performing concentration and integration on each of the key frames having the same preset bit to generate a concentrated video. In other words, through determining the preset bit information corresponding to each of the video frames, video frames shot by the camera at a same preset bit are concentrated to a same video and thus the video concentration on a set scene can be implemented; and the problem that existing video concentration methods cannot perform the video concentration on the set scene is solved and thus the inquiry requirement on a scene is also met.

The embodiment of the invention discloses a pre-calculation result generation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a feature vector set, the feature vector set being determined based on a dimension combination queried by a query statement within a preset time; inputting the feature vector set into a query popularity model, obtaining the score of each feature vector in the feature vector set, and obtaining the query popularity model based on data table static features and historical query statements through pre-training; determining an expected score value of each feature vector according to the score of each feature vector; and based on the expected score value of the feature vector, screening out a target feature vector meeting the query expectation from the feature vector set, and performing pre-calculation based on the target feature vector. According to the embodiment of the invention, the calculation efficiency of the pre-calculation result is high, the number of calculation results is small, less storage space is occupied, and the storage overhead is reduced.

The invention discloses a method for customizing and exporting data in a service management system, which comprises the following steps that: in a first stage, a, a client transmits a complete class name to a server; b, the server performs dynamic loading and acquires an attribute information list in a reflection mode; c, annotation and extension information are obtained through the field list; d,a user interaction interface is generated; in the second stage, a, a user selects on the interactive interface; b, the server carries out SQL splicing; and c, the inquired result is exported. Compared with the prior art, the method has the advantages that the export function module is extracted and decoupled from the specific service system, and the functions of user-visualized and understandablefield selection, user-defined query condition and sorting mode are achieved. According to the method, a large amount of repeated workloads are saved, the working efficiency is improved, the development cost is reduced, the user perception and satisfaction are improved, and the query requirements of users in various aspects are more flexibly met.

The invention relates to a global mobile communication system technology and discloses a microphone calibration information acquiring method and a microphone. In the invention, a mark used for marking whether the microphone is calibrated or not is arranged in a coded program in the microphone, the value of the mark is set into a calibrated value after the microphone is calibrated, and the information whether the microphone is calibrated or not is acquired by querying the value of the mark. A tester can acquire the information whether the microphone is calibrated or not conveniently and simply by querying the mark, therefore, the test operation carried out on the microphone which is not calibrated or loses calibration data is effectively avoided, and the invalid test is avoided to the largest extent.

The invention discloses an information matching analysis method and device, a computer system and a readable storage medium, belonging to the technical field of big data. The method comprises the following steps: creating a database in which pathological information and case data are stored; receiving a retrieval condition output by a user side, and extracting case information from the database according to the retrieval condition; comparing the matching degree of the retrieval condition and the structured information of the case information to obtain a structured score; comparing the matchingdegree of the retrieval condition and the unstructured information of the case information to obtain an unstructured score; according to the structured score and the unstructured score, acquiring association scores expressing the matching degree between the retrieval condition and the case information; based on the association scores of the retrieval condition and the case information, arrangingthe association scores to obtain a score set; and outputting the case information to the user side according to the sequence of the associated scores in the score set. According to the invention, a doctor can adjust the importance degree of each piece of information in the retrieval condition according to requirements, so query precision is improved.

The invention discloses a data processing method and device based on a block chain, and the method comprises the steps: receiving a plurality of pieces of operation data from a plurality of data chains in the block chain, with the operation data comprising operation execution sequence information and operation basic information; sequentially storing the plurality of job data in a local database according to the job execution sequence information, wherein the local database has an index set in advance according to the job basic information; and sending the corresponding job data to a subscription mechanism producer according to a predetermined subscription mechanism so as to forward the job data to a corresponding subscription mechanism consumer. The query requirements of different job datacan be met, and the query efficiency can be improved through the indexes set based on the basic job information.

The invention discloses a data query method and device based on pre-computation, and relates to the technical field of data processing, which improves the working efficiency of data query.
