推荐答案
SELECT * FROM tbUserDetails WHERE UserNAME = ?
这里 ?表示您要从数据库中获取哪些用户信息.您必须对此清楚.您可以像这样使用:
Here ? means which user information you want to fetch from database. You''ll have to be clear on that. You can use like:
SELECT * FROM tbUserDetails WHERE UserNAME = 'amit' *表示表中的所有列.如果只需要表中的特定列，则可以将 *替换为用逗号分隔的列名.像这样尝试:
Here * means all the columns from the table. If you want only specific columns from table then you can replace the * to your column names separated with comma. Try like this:
SELECT FName, LName, Address, EmailID, PhoneNo FROM tbUserDetails WHERE UserNAME = 'amit'
