As shown in fig. 1, an embodiment of the present invention is implemented by: acquiring database updating information and generating an SQL statement for updating the database; inputting the SQL sentences updated by the database into a language conversion relational database, and outputting the SQL sentences updated by the database of the target language type; the language conversion relation library is established according to conversion relations among SQL sentences of multiple language types; according to the method and the system, version iteration is carried out on the database of the target language type according to the SQL sentences updated by the database of the target language type and the existing SQL sentences of the database of the target language type, and compared with the prior art that the SQL sentences of multiple language types need to be written manually during the database version iteration, the SQL sentences updated by the database can be converted into the SQL sentences of multiple language types based on the language conversion relational database, so that the workload of business personnel is reduced, and the efficiency and the accuracy of the database version iteration are improved.
In step 101, a user may input database update information through an interactive interface, where the database update information may include: newly creating names and versions of databases, for example, information such as Mysql, Oracle and the like, field information such as names, field types, field lengths, whether fields are empty, default values and the like of the newly created databases, and attribute information such as indexes, constraint conditions, main keys and the like of the newly created databases, and the database update information may also include other information, which is not limited in the present invention.
The user can add new database and database table at any time, also can add or modify the field and attribute information of the table at any time, and can generate the SQL sentence of the corresponding database update according to the database update information input by the user. The interactive interface can be used for a user to check, manage and enter database information, the interactive interface can adopt an interface style of a document style, the convenience and the rapidness are realized, a new page can be established for each database, when a database table is newly established, a form is equivalently added on the page, each row in the form is a field of the database table, and the database updating information input by the user can be printed with a timestamp for storage for inquiring at any time.

In specific implementation, in step 1021 and step 1022, the conversion relationship between the SQL statements of multiple language types may be stored in the language conversion relational library, for example, syntax differences such as correspondence, constraints, indexes, and the like between the field type of Mysql and the field type of Oracle and the field type of the universal language may be stored in the language conversion relational library, and loaded into a memory when the system is started, and used for reading when the SQL statements are converted, where the universal language may be a programming language familiar to business personnel. In addition, the language types, such as GP, Sybase and the like, can be dynamically expanded according to the actual requirements of users.
The core function of the language conversion relation library is the corresponding relation and conversion relation between the universal language and the SQL sentences of multiple language types, as shown in table 1, the variable length Text type of the universal language is String, the variable length Text type of Mysql is Varchar, the variable length Text type of Oracle is Varchar2, in table 1, the large String type of the universal language and Mysql is Text, and the large String type of Oracle is Clob.

In specific implementation, in step 102, the SQL statement of the general language type may be input into the language conversion relational database, and the SQL statement updated by the database of the target language type may be output, where the target language type may be specified by a user and may be one or more types. It should be noted that, a Create statement or an enter statement may also be correspondingly generated according to whether the database Table and the field are created at the same time, if the database Table and the field are created at the same time, the Create statement is generated, and if the database Table is created before, and the updating is only to modify or Add the field, an enter Table Add column statement is generated.
In specific implementation, in step 103, version iteration may be performed on the database of the target language type according to the SQL statement updated by the database of the target language type and the existing SQL statement of the database of the target language type, for example: business personnel build a database, and there are 10 pieces of database tables in the database, the existing SQL statement of the database can be the SQL statement of the 10 pieces of database tables, because of business requirements, the user adds 2 pieces of database tables, can generate the SQL statement of the newly added 2 pieces of database tables, and can generate the full-base SQL statement containing the complete 12 pieces of database tables, and can perform version iteration of the database according to the SQL statement of the newly added 2 pieces of database tables or the full-base SQL statement of the 12 pieces of database tables based on user requirements, so that in the whole software life cycle, after the user inputs update information each time, the corresponding SQL statement updated by the database or all the SQL statements of the database can be generated, and version iteration of the database is realized.
In one embodiment, the method may further comprise:
according to the SQL statements updated by the database of the target language type and the existing SQL statements of the database of the target language type, deploying the running environment of the software corresponding to the database of the target language type;
the SQL statement for updating the database of the target language type comprises the following steps: creating SQL sentences of the database table and/or modifying SQL sentences of the database table.
In specific implementation, based on user requirements, according to the SQL statements updated by the database or all the SQL statements of the database, the operating environment deployment or performance test can be performed on the software corresponding to the database, so as to implement various software functions.
In one embodiment, the method may further comprise:
storing SQL statements updated by the database of the target language type, and recording a timestamp of the database update of the target language type;
and querying the SQL sentences of the database update or all the SQL sentences of the database of multiple language types corresponding to different timestamps based on different timestamps.
In specific implementation, after the user performs update operations such as addition, modification, deletion, and the like, the SQL statement updated by the database of the target language type may be stored according to the update timestamp, and an update log may be generated, which may include: updating running water, updating operators, updating operation time and other information. Subsequently, the SQL sentences updated by the databases of various language types or all the SQL sentences of the databases corresponding to any timestamp can be inquired based on different timestamps, and the user can derive the SQL sentences updated by the databases of any language types or all the SQL sentences of the databases of any timestamp according to actual requirements for the user to use and deploy at any time, so that the management of the database versions of the database platform in the whole software life cycle process can be realized.
The following is a specific example to facilitate an understanding of how the invention may be practiced.
Firstly, establishing a language conversion relation library according to the conversion relation among SQL sentences of a plurality of language types, and then executing the following steps:
