Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearly; below in conjunction with the accompanying drawing in the embodiment of the present invention; technical scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is a part of embodiment of the present invention, rather than whole embodiments, based on the embodiment in the present invention; the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly falls into the scope of protection of the invention。
As it is shown in figure 1, a kind of method embodiments providing DLL and database synchronization, the method may comprise steps of:
S0: prefab data storehouse upgrade file in DLL；
S1: determine the current version of described DLL and the current version of data base；
S2: judge whether the current version of described DLL mates with the current version of described data base, if it does not match, perform S3；
S3: obtain described database upgrade file from described DLL, upgrades to described data base according to described database upgrade file。
By a kind of method embodiments providing DLL and database synchronization, by prefabricated for database upgrade file in DLL, whether the current version of current version with data base by judging DLL mates determines whether database upgrade, when not mating, from DLL, obtain database upgrade file data base is upgraded, make DLL and database synchronization, without being upgraded by special instrument, without manually upgrading, achieve DLL synchronization with data base simplerly。
In a kind of possible implementation, described prefab data storehouse upgrade file in DLL, including:
The database upgrade file that each version of prefabricated described DLL is corresponding in described DLL；
Described S3, including:
A1: determine the fit version of the described DLL matched with the current version of described data base；
A2: determine the intermediate releases of described DLL between the fit version of described DLL and the current version of described DLL；
A3: obtain the intermediate database upgrade file that each intermediate releases of described DLL is corresponding from described DLL, and the current database upgrade file that the current version of described DLL is corresponding；
A4: according to each intermediate database upgrade file and described current database upgrade file, described data base is upgraded。
Owing to DLL needs Tong Bu upgrading with data base, will not there is exception in such guarantee, therefore, each version of DLL has the database upgrade file of correspondence when calling DLL。When differing multiple version between the current version and the current version of data base of DLL, it is necessary to the version of current data base is carried out the upgrading of version one by one, until being upgraded to the version that the current version with DLL matches。For example, the current version of data base is version 1.0, the current version of DLL is edition 4 .0, the version of the DLL matched with the current version of data base is version 1.0, between version 1.0 to edition 4 .0, also has version 2 .0 and version 3 .0, therefore, when upgrade database, it is necessary to pass sequentially through the database upgrade file corresponding for version 2 .0 of DLL, the database upgrade file corresponding for version 3 .0 of DLL, DLL database upgrade file corresponding for edition 4 .0 data base is upgraded。
In a kind of possible implementation, the method also includes: pre-set version sign table, and in described version sign table, storage has the matching relationship of the version number of DLL and the version number of data base；
The described database upgrade file that each version of prefabricated described DLL is corresponding in described DLL, including: the database upgrade file that the version number of each version of prefabricated described DLL is corresponding in described DLL；
Described S1, comprises determining that the current version number of described DLL and the current version number of data base；
Described S2, including: indicate the described matching relationship in table according to described version, it is judged that whether the current version number of described DLL mates with the current version number of described data base, if it does not match, perform A1；
Described A1, including:
The described matching relationship in table is indicated, it is determined that the fit version number of the fit version of the described DLL matched with the current version of described data base according to described version；
Described A2, including: indicate table according to described version, it is determined that the intermediate releases number of the described DLL between fit version number and the current version number of described DLL of described DLL；
Described A3, including:
The intermediate database upgrade file that each intermediate releases number of described DLL is corresponding is obtained from described DLL, and the current database upgrade file that the current version number of described DLL is corresponding。
In this implementation, identify version by version number, each version of DLL by unique version number as mark, each version of data base by unique version number as mark。Above-mentioned matching relationship refers to that the version number of DLL corresponding in version sign table and the version number of data base match。For example, it is as shown in table 1 that a kind of version indicates table, in this implementation, the version number of the DLL matched can be adopted identical version number with the version number of data base, such as: the version A of DLL and the version B of data base matches, then the version number of the version number of the version A of DLL and the version B of data base can be disposed as 3.0.5801.30364。
Table 1
In order to determine the current version of DLL as soon as possible, in a kind of possible implementation, described S1, including: the current version of described DLL is determined according to the destructor function of described DLL。
In a kind of possible implementation, the method also includes: using the described database upgrade file resource file as described DLL。By this implementation, it is possible to the DLL of database upgrade file with corresponding version is bound。
In a kind of possible implementation, described database upgrade file includes: the SQL file of database upgrade。In this implementation, the SQL file of database upgrade includes the SQL for database upgrade。Specifically, the SQL file of database upgrade can include code below:
--DBVERSION2.0.4365
