要在连字符后拆分列,请使用SUBSTRING_INDEX()方法-
select substring_index(yourColumnName,'-',-1) AS anyAliasName from yourTableName;
让我们首先创建一个表-
create table DemoTable -> ( -> StreetName text -> );
使用插入命令在表中插入一些记录-
insert into DemoTable values('Paris Hill St.-CA-83745646') ; insert into DemoTable values('502 South Armstrong Street-9948443');
使用select语句显示表中的所有记录-
select *from DemoTable;
这将产生以下输出-
+------------------------------------+ | StreetName | +------------------------------------+ | Paris Hill St.-CA-83745646 | | 502 South Armstrong Street-9948443 | +------------------------------------+ 2 rows in set (0.00 sec)
以下是在特定字符后拆分一列的查询-
select substring_index(StreetName,'-',-1) AS Split from DemoTable;
这将产生以下输出-
+----------+ | Split | +----------+ | 83745646 | | 9948443 | +----------+ 2 rows in set (0.00 sec)
