關於Mysql查詢帶單引號及插入帶單引號字符串問題

1.轉為帶參數查詢

String sql=""select id from student where name='?';

Connection connect = DriverManager.getConnection( "jdbc:mysql://10.82.80.7:3306/haitao" , "root" , "123456" );

PreparedStatement pStmt = connect .prepareStatement( sql );

pStmt .setString(1, name );

pStmt .executeUpdate();

2.將字符串中的單引號轉換為兩個單引號。
