Embodiment 1

[0025] In practical applications, the database access method can be implemented by computer programs, such as application software, etc.; or, the database access method can also be implemented as a medium that stores related computer programs, such as U disk, cloud disk, etc.; or, The database access method can also be realized by an entity device integrated or installed with a relevant computer program, such as a chip, a mobile smart device, and the like.

[0026] figure 1 It is a flow chart of the database access method provided in Embodiment 1 of the present application. like figure 1 As shown, the database access method provided in this embodiment includes:

[0027] Step 101, acquiring a database access encapsulation function instruction.

[0028] This instruction can be used as a function call instruction for programmers to write programs. The database access encapsulation function internally encapsulates the database access underlying function, and the database acces...

Embodiment 2

[0037] This embodiment optimizes the above database access method on the basis of the above embodiments.

[0038] A first implementation manner: the above-mentioned database access encapsulation function instruction may be: a connection database function instruction, for example: int ConnectDB(). Then the above-mentioned underlying function of the database is the underlying function of connecting to the database encapsulated in the function of connecting to the data. The above step 103 may specifically be: establish a connection to the database corresponding to the database name according to the underlying function of connecting to the database.

[0039] Specifically, the underlying function of connecting to the database is an OCI underlying function, including: an OCI initialization function, an environment initialization function, a function of applying for an OCI handle, and an OCI login function. For example: the OCI initialization function is OCIInitialize(), the environ...

Embodiment 3

[0067] Image 6 It is a schematic structural diagram of a database access device provided in Embodiment 3 of the present application. like Image 6 As shown, this embodiment provides a database access device, including: a memory 601, a processor 602, and a computer program. Wherein, the computer program is stored in the memory 601 and is configured to be executed by the processor 602 to implement the method provided by any one of the above contents.

[0068] This embodiment also provides a computer-readable storage medium, on which a computer program is stored, and the computer program is executed by a processor to implement the method provided by any one of the contents above.

Abstract

The embodiment of the invention provides a database access method and equipment and a storage medium, and the method comprises the steps: obtaining a database access packaging function instruction; obtaining a database access underlying function packaged in a database access packaging function according to the database access packaging function instruction, and obtaining a preset configuration file, wherein a database name is pre-stored in the configuration file; and executing an access operation on a database corresponding to the database name according to the database underlying function. According to the database access method and equipment and the storage medium provided by the embodiment of the invention, the problem that the statement content of an existing OTL data access technologyis relatively complex can be solved.

Description

technical field [0001] The present application relates to database access technology, in particular to a database access method, device and storage medium. Background technique [0002] At present, the methods for accessing the Oracle database in the Visual C++ environment mainly include Open Database Connectivity (ODBC for short), ActiveX Data Objects (ActiveX Data Objects, ADO for short) and Oracle Call Interface (OCI for short). ). Among them, ODBC is a unified interface provided for database applications to access relational databases. To access a database, an application must first register a data source with the ODBC manager. The manager provides the database location, database type and ODBC driver and other information to establish the connection between ODBC and a specific database, the process is relatively cumbersome. Access using ADO must import its library. Compared with ODBC access, it is simpler and can save network traffic to the greatest extent, but it is n...
