如何在MySQL中右对齐的列对齐？
您可以LPAD()从MySQL使用它。让我们首先创建一个表-
mysql> create table DemoTable ( FullName varchar(100) );
使用插入命令在表中插入记录-
mysql> insert into DemoTable values('John Smith');
mysql> insert into DemoTable values('David Miller');
mysql> insert into DemoTable values('Sam Williams');
mysql> insert into DemoTable values('Carol Taylor');使用选择命令显示表中的记录-
mysql> select *from DemoTable;
这将产生以下输出-
+--------------+ | FullName | +--------------+ | John Smith | | David Miller | | Sam Williams | | Carol Taylor | +--------------+ 4 rows in set (0.00 sec)
以下是将列右对齐的查询-
mysql> select lpad(FullName,70,' ') from DemoTable;
这将产生以下输出-
+------------------------------------------------------------------------+ | lpad(FullName,70,' ') | +------------------------------------------------------------------------+ | John Smith | | David Miller | | Sam Williams | | Carol Taylor | +------------------------------------------------------------------------+ 4 rows in set (0.00 sec)
