XML has become the mainstream in different languages and data sources. In these DRP projects, Wang Yong also mentioned the use of XML to exchange data in different databases for security and flexibility. However, he just mentioned that there is such a method that does part of the work. I think this technology is very practical. I will complete this process here.

Use SQL scripts to import data to different databases to avoid duplication. Preface I believe everyone has some experience. No matter what language, once you see repetitive code in the code, you want to encapsulate it for reuse. This is also true for SQL, if we do not have an interface to maintain and frequently perform operations, we will write a script to avoid re-writing it again next time, but this invo

PLSQL Developer can synchronize table structures and table data of different databases. The Tools Options in the PLSQL Developer menu contain the Compare User Objects and Compare Table Data functions. 1. Tools --> compare user objects This function is used to compare objects owned by different users (including tables, sequence, function, procedure, and view) and

Replication between mysql tables, the same database and different databases, mysql table replication Database Mysql statement We can first export the structure of table t1 under test, and then create a new table test1.t1. Execute the following statement Insert into test1.t1 select * from test. t1 limit 2 (limit) In a database Insert into t1 select * from t2 limit 2 If the table structure is

One disadvantage of using parameterized DbCommand is that the code that requires the parameter will only apply to providers that support the same syntax. OLE DB, SqlClient, and Oracle providers all use different syntaxes. For example, the SQL syntax for naming and specifying parameters uses the @ sign, and the OLE DB parameter syntax requires a question mark (?) as the parameter placeholder, and the Oracle provider uses a colon (:).String sqlstr = "SE

Operate tables in different databases at the same time. does it support transactions? mysql MYSQL database There are two tables in database A and database B, and two tables in table A and B are operated at the same time. it is innodb that supports transaction rollback .. There are two situations: Database A and database B are on the same server Database A and database B are not on the same server Cons

Database merging Q: My account is the ACC database. The two database tables have the same structure.For example, the first database has a table house.ID (automatic number) Name Number Address1 Zhang Yi 001 District 12 Zhang 'er 002 District 13 zhangsan 003 Zone 2The second database also has a table house.ID (automatic number) Name Number Address1 zhangsan 003 Zone 22, 4, 005, zone 13 zhangwu006 Zone 2Objective: To merge data into a database without duplicate informationAfter merging
