Problems solved by technology

[0003] On the one hand, these software will read the content of each block file one by one, and then merge them. When the number of block files is very large, the merge speed will be very slow;
[0004] On the other hand, some block files will contain multiple data variables, but not all data variables need to be read, and in practical applications, these software will often read and combine all data variables, resulting in Reduced merge and data read speed

Abstract

The invention provides a data reading method and device and electronic equipment, and the method comprises the steps of obtaining a source file from a database according to a query condition; judgingwhether the source file is a blocked file or not; when the source file is a block file, obtaining all file handles corresponding to the query condition in each block file; extracting target data corresponding to the file handle in the source file; and completing data merging according to the spatial position relationship of each block. The method and the device are used for quickly extracting target data from a source file according to query conditions input by a user.

Description

technical field [0001] The present application relates to the field of computer technology, in particular, to a data reading method, device and electronic equipment. Background technique [0002] The main problem of existing block file merging software is that the merging speed is very slow. There are mainly two reasons for this: [0003] On the one hand, these software will read the content of each block file one by one, and then merge them. When the number of block files is very large, the merge speed will be very slow; [0004] On the other hand, some block files will contain multiple data variables, but not all data variables need to be read, and in practical applications, these software will often read and merge all data variables, resulting in Reduced merging and data read speed. Contents of the invention [0005] The purpose of the embodiments of the present application is to provide a data reading method, device, and electronic device for quickly extracting targ...
