We all know that char (integer_expression) converts the ASCII code to characters. When Integer_expression is an integer between 0 and 255. If the integer expression is not within this range, a NULL value is returned. These are all official information. Specific reference https://msdn.microsoft.com/zh-cn/library/ms187323 (v=sql.120). aspxHowever, during our most recent SQL Server 2005 migration upgrade to SQL Server 2014, we found some problems with the official documentation describing the funct

The JDBC Connection database query data returns the resultset result set at all times. Key value pairs are stored in the resultset. We can first get the key value, and then we get the value we want with the key value. So how do we get the key value? Look at the following code:try {listFor SQL Server and Oracle databases, we can useString key = rsmd.getColumnName(i + 1)来获取Key值，但是对于Mysql数据库，当我们使用聚合函数时如：select count(*) as stu_count from student，我们会发现这时取得
