Method and device for splicing data records

The invention provides a method and a device for splicing data records. The method comprises the following steps: a data table appointing step: appointing at least two data tables to be subjected to data record splicing according to a data table appointing operation of a user; an associated field appointing step: respectively appointing corresponding associated fields in the fields of the data tables according to an associated field appointing operation of a user; an output field configuration step: configuring a source field of the output field and a processing mode for the source field according to an output field configuration operation of a user; and an output field generation step of processing the field value of the configured source field according to the configured processing mode for the to-be-spliced data records with the same field value in the corresponding associated fields in each data table so as to generate the field value of the output field. According to the method and the device, the flexib
