At present, in the process of migrating a database table structure, developers often encounter the situation that the constraints of creating sentences, tables, fields, primary keys, indexes and the like between different original databases and new databases are inconsistent. This requires a deep understanding of the knowledge about the two databases by the developer, which, once biased, can affect the progress of the subsequent databases on-line. In addition, the modification workload for each system is huge, the functions, storage processes, sequences, views and the like among the databases need to be changed one by one, but the system and the database operation have a many-to-many relationship, which is extremely easy to cause errors in the migration process of the databases.

In this embodiment, the manner of obtaining the configuration information of the new database may be: determining type information of a new database; configuration information input by a user based on the type information is received.
The configuration information comprises a database type name and a table construction grammar of a new database. If the type of the new database is the existing type, directly acquiring the configuration information of the database of the type; if the type of the new database is not available at present, a developer self-defines the type of the new database through an interactive interface and inputs configuration information of the new database through the interactive interface, wherein the table-building grammar can be understood as writing rules of information such as multiple fields, multiple indexes, a main key external key and the like.
The first table-building statement may be understood as a table-building statement of the original database, where the table-building statement includes table structure information in the original database. In this embodiment, the first table-building statement may be directly extracted from the original database system.
S120, converting the first list-building sentence based on the configuration information to obtain a second list-building sentence of the new database.
In this embodiment, the method for building the table of the new database is learned by identifying keywords in the table-building grammar in the configuration information. Converting the first list-building sentence based on the configuration information may be understood as: and converting the first list-building sentence by a list-building method identified by the list-building grammar in the configuration information to obtain a second list-building sentence of the new database. The process may be: and re-combining the fields contained in the first table-building statement according to the table structure information of the new database, thereby obtaining a second table-building statement of the new database.
Optionally, before converting the first table-building sentence based on the configuration information, the method further includes the following steps: acquiring first server address information of a new database and second server address information of an original database; testing connectivity between the new database and the original database based on the first server address information and the second server address information; accordingly, the process of converting the first table-building sentence based on the configuration information may be: if the connectivity test between the new database and the original database is passed, converting the first table-building sentence based on the configuration information.
The first server address information may be understood as an address of a server corresponding to the new database, and the second server address information may be understood as an address of a server corresponding to the original database. In this embodiment, the manner of testing connectivity between the new database and the original database based on the first server address information and the second server address information may be: logging in a first server through address information of the first server, then sending an access request to a second server through address information of the second server in the first server, and if the first server receives response information returned by the second server, testing connectivity between the first server and the second server; logging in a second server through the address information of the second server, then sending an access request to the first server through the address information of the first server in the second server, and if the second server receives response information returned by the first server, testing connectivity between the first server and the second server.

The method for pre-building the table based on the second table building sentence can be as follows: and pre-creating a table structure in a preset storage space according to the second table-building statement, and determining whether the second table-building statement can successfully create the table structure. When the pre-built table fails or is abnormal, the second table-building sentence is indicated to have a problem, the second table-building sentence is confirmed to be failed in verification and needs to be corrected, at the moment, the second table-building sentence failed in verification is displayed, and a user manually corrects the second table-building sentence failed in verification to obtain a corrected second table-building sentence. In this embodiment, the second table-building sentence is checked, so that the efficiency and accuracy of the subsequent table structure migration can be improved.

Wherein the database operation statement (Structured Query Language, SQL) comprises: adding sentences, deleting sentences, modifying sentences and inquiring sentences. The test cases comprise database operation data and corresponding test data. In this embodiment, the database operation statement is obtained by parsing a database operation file, which may be an xml format file. Test data may be generated based on a table field type corresponding to the database operation statement.
Specifically, the method for acquiring the database operation statement may be: acquiring a database operation file; and analyzing the database operation file to obtain a database operation statement.
The method for acquiring the database operation file may be: firstly, a catalog storing database operation (xml format) files is obtained, and then all database operation files under the catalog and sub-catalog are extracted. After the data operation file is obtained, the database operation file is analyzed, and the database operation statement is obtained.
Optionally, before parsing the database operation file, the method further includes the following steps: checking the database operation file, and displaying the database operation file which does not pass the checking; and receiving marks or modifications of the database operation files which are not checked by the user.
In this embodiment, it is first checked whether the database operation files conform to the specifications of the database framework, and for the database operation files that do not conform to the specifications, the database operation files are displayed to the user in the form of a list, and the user may mark the database operation files as not tested or correct the database operation files.
Specifically, the manner of generating the test cases based on the database operation statement may be: acquiring a table field type corresponding to a database operation statement; generating test data based on the table field type; and generating a test case according to the database operation statement and the test data.
The table field type may be a character type, a date type, a number type, a boolean type, a binary type, and the like. Generating test data based on table field type can be understood as: if the table field type is a character string type, randomly generating test data of the character string type; if the table field type is a date type, randomly generating test data of the date type; if the table field type is the Boolean type, randomly generating test data of the Boolean type; if the table field type is binary type, test data of binary type is randomly generated. And finally, combining the database operation statement and the test data to obtain a test case.
Specifically, the data operation test method for the new database based on the test cases can be as follows: if the database operation statement is any one of a deletion statement, a modification statement and a query statement, inserting test data into a table structure corresponding to the database operation statement in the new database; and carrying out corresponding data operation test on the new database based on the database operation statement.
In this embodiment, if the database operation statement is a delete statement, the test data corresponding to the delete statement is inserted into the table structure corresponding to the delete statement in the new database, and then the delete operation is performed on the database based on the delete statement. If the database operation statement is a modification statement, inserting test data corresponding to the modification statement into a table structure corresponding to the modification statement in the new database, and then carrying out modification operation on the database based on the modification statement. If the database operation statement is a query statement, inserting test data corresponding to the query statement into a table structure corresponding to the query statement in the new database, and then carrying out query operation on the database based on the query statement.
Specifically, the data operation test method for the new database based on the test cases can be as follows: and if the data operation statement is an add statement, performing an add operation test on the new database based on the add statement.
Optionally, after the data manipulation test is performed on the new database based on the test cases, the method further comprises the following steps: acquiring a test case which does not pass the test; correcting the database operation sentences in the test cases which do not pass the test; and re-performing corresponding data operation test on the new database based on the corrected test cases.
Wherein, the test failure can be understood as that the database operation statement cannot execute the corresponding operation or fails to execute the operation on the new database. For an add statement, test failing may be understood as the add statement failing to perform the add data operation or add data failure on the new database; the add statement is revised and the data adding operation is performed again on the new database based on the revised add statement. For a delete statement, test failing may be interpreted as the delete statement failing to perform the operation of deleting data or failing to delete data on the new database; the delete statement is revised and the delete operation is performed again on the new database based on the revised delete statement. For a modification statement, the test does not pass or can be understood as that the modification statement cannot execute the operation of modifying the data on the new database or fails to modify the data; the modification statement is revised, and the data modification operation is carried out on the new database again based on the revised modification statement. For a query statement, a test failing may be understood as the query statement failing to perform an operation of querying data on a new database or failing to query data. The query statement is revised, and the operation of querying the data is carried out again on the new database based on the revised query statement.
