Embodiment Construction

[0019] figure 1 It is a schematic flowchart of a method for processing a business table provided by an embodiment of the present invention. The method in this embodiment can be applied to any database. Such as figure 1 As shown, the method provided in this embodiment includes:

[0020] 101. When a row of data content is added or decreased in the data content column of any business table in the database, acquire the name of the business table to be processed whose data content column changes;

[0021] The database of this embodiment includes a plurality of business tables, and a corresponding name and a sequence table corresponding to each business table name are defined for each business table. In this embodiment, an initial A sequence value and a step size, wherein the step size is a preset value representing the change rule of the sequence value in the sequence table. Wherein, the initial sequence value may be 0 or 1, for example.

[0022] Assume that a plurality of stu...

Abstract

The invention provides a service table processing method and device; the method comprises the following steps: obtaining the name of a service table with changing data content columns when data-in-line content is added or reduced in the data content columns of a random service table in a database; searching a sequence table corresponding to the name of the service table according to the service table name, obtaining a present sequence value and increment contained in the sequence table, wherein the increment is a preset value representing sequence value changing rule in the sequence table; adding or subtracting the obtained present sequence value and the increment, plugging the added or subtracted sequence value into an identification attribute column of the service table, wherein the added or subtracted sequence value is matched with an identification attribute item of the added or reduced data-in-line content. The method and device suit for all databases, and can solve the application restricted problems existing in a digit sequence generation method provided by an existing database.

Description

technical field [0001] The invention relates to database technology, in particular to a method and device for processing business tables. Background technique [0002] In the prior art, the database provides two methods for generating digital sequences, one of which is to define a column with an Identity attribute, referred to as an Identity column, when the Identity column is used to define a business table, and in each business table When a row is inserted in the business table, a value will be automatically generated for the Identity column of the business table; another method is to create a sequence object, which can be referenced by a sequence expression (sequence expression), which can be used for a row in the business table Automatically generate a serial number, which is a set of equally spaced values ​​(sequence of numbers). [0003] However, the biggest difference between Identity and sequence is: Identity is only specified on a certain column in the business tab...
