This article will not be practical. Some resources are quite good. Let's share a link with you. The online cool predecessors can always create benefits for our elders !!! Young !!! Haha! I have found a good website on the Internet, which is better than the textbooks. I would like to share it with everyone. PS: Thank you !! SQL Tutorial: W3School At the same time, I attached a note photo which I started learning SQL statements in the Early Learning Mod

When data is inserted in SQLite, a default statement is a transaction, and disk operations are performed on every piece of data. If you need to execute SQL statements frequently, you can enable transactions explicitly to improve efficiency. Database. begintransaction (); // manually set the start transaction // Data insertion operation cycle Database. settransactionsuccessful (); // sets whether the transaction is successfully processed. If this

database table structure and other information can be found. The search is also a problem when the contents of the write to the database are encrypted. 2. Encrypt the database file The whole database is encrypted, which can basically solve the information security problem of the database. The existing SQLite encryption is basically implemented in this way. Here is an open source encryption tool Sqlcipher, installation method can refer to the offici

SQLite is a lightweight database designed for embedded devices. It has only five data types: Null: NULL Integer: integer Real: Floating Point Number Text: String BLOB: Big Data In SQLite, the Boolean and date types are not specifically designed, because the boolean type can replace true and false with integer 0 and 1, the date type can have text, real, and integer values in a specific format instead of disp

In the previous lecture on Android, SQLite reads data by PAGE and only displays data in text boxes. This time, we will go deeper and implement and encapsulate an SQL paging table control, data can be displayed on pages or in tables. Let's take a look at the animation program running in this article: This SQL paging table control is mainly divided into two parts: "table area" and "page bar", which are imp

first, let's talk about the concept of SQLite: SQLite is an open-source embedded relational database, which can reduce the overhead of the application Program to manage data, SQLite is portable, easy to use, small, efficient, and reliable. Currently, sqlite3 is integrated in Android.

Today, let's summarize the application of SQLite database in Android system. First look at some of the database introduction:The SQLite database is an untyped database, which means that you can save any type of data to any column in any table, no matter what type the column is declared in when the table is create. Because SQL
