Manipulating SQLite databases with transactions

Use the Sqlitedatabase BeginTransaction () method to open a transaction where the program executes to the Endtransaction () method to check whether the flag of the transaction is successful if the program executes to Endtransaction () The Settransactionsuccessful () method was previously called to set the transaction's flag to commit the transaction successfully, and if the Settransactionsuccessful () method was not called, the transaction is rolled back. Examples of use are as follows:
Sqlitedatabase db = ....;    Db.begintransaction ();//Start transaction try {Db.execsql ("INSERT into person (name, age) VALUES (?,?)", New object[]{"Preach Wisdom Podcast", 4}); Db.execsql ("Update person set name=?")    Where personid=? ", New object[]{" Preach Wisdom ", 1}); Db.settransactionsuccessful ();//Call this method to commit the current transaction when it executes to endtransaction (), and if this method is not called, rollback the transaction} finally {db.endtransaction ();// The flag of the transaction determines whether to commit the transaction or rollback the transaction} db.close (); The above two SQL statements are executed in the same transaction.
