Embodiment Construction

[0036] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0037] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0038] The inventor understands that although the batch SQL execution supported by the database client can provide convenience for executing multiple SQL tasks, it is not easy to find dangerous operations in the batch SQL. If a specific dangerous SQL operation cannot be discovered in time, the possible dangerous SQL operation cannot be audited in a timely and ...

Abstract

The invention provides a statement extraction method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining to-be-processed batch SQL data; according to a preset matching rule, determining an offset position of each SQL statement contained in the to-be-processed batch SQL data; and according to the offset position, extracting each SQL statement from the to-be-processed batch SQL data, and constructing an SQL statement set.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, relates to a sentence extraction method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] Existing database clients support batch SQL (Structured Query Language, Structured Query Language) execution and batch result return, which provides convenience for executing multiple SQL tasks. But this also brings some challenges to the security audit, especially for some undisclosed database protocol data. If there may be some dangerous SQL operations in batch SQL, the dangerous SQL operations may not be discovered in time due to the existence of batch SQL. Contents of the invention [0003] The purpose of this application is to provide a statement extraction method, device, electronic equipment and computer-readable storage medium, which can solve the problem that dangerous SQL operations in batch SQL are not easy to...
