When the qsqldatabase::adddatabase is first run, a default connection is generated while generating the SQLite file:Qsqldatabase database = Qsqldatabase::adddatabase ("Qsqlite");QString myconn = M_createname = Database.connectionname

First, attach database:The ATTACH database statement adds another file to the current connection, and if the file name is ": Memory:", we can treat it as a memory database and the memory database cannot be persisted to the disk file. If you

To SQLite both hate and love, in small projects, with SQLite developed very convenient, efficient enough. The drawback is that SQLite has streamlined some functions and related functions. such as stored procedures, DATEDIFF, does not support

SQLite is a very small embedded open source database software. That is to say, there is no independent maintenance process, and all maintenance comes fromProgramItself. It uses a file to store the entire database, which is very convenient to operate.

You can use the begintransaction () method of sqlitedatabase to start a transaction,ProgramWhen you run the endtransaction () method, the system checks whether the transaction flag is successful. If the settransactionsuccessful () method is called

This analysis is called a simple version, because we plan to analyze a more complex database file later to gain a deep understanding of the structure implemented by the B-tree of the SQLite database. It is a good learning method from a simple one,

In actual programming and development, we often need to process the storage of large-capacity binary data, such as slices or music. For these binary data (BLOB fields), we cannot simply insert or query the data as if we were dealing with common text.

Preface: Thank you for your attention. I didn't expect so many people to be interested. I am also excited and stressed that I have been using SQLite for just a few days and have never used it in actual development. I only came to study it based on
