我正在运行MySQL查询.但是当从表单输入添加新行时,我收到此错误:

Error: Can't update table 'brandnames' in stored function/trigger because it is 
already used by statement which invoked this stored function/trigger.

从代码:

CREATE TRIGGER `capital` AFTER INSERT ON `brandnames`
FOR EACH
ROW UPDATE brandnames
SET bname = CONCAT( UCASE( LEFT( bname, 1 ) ) , LCASE( SUBSTRING( bname, 2 ) ) )

这个错误是什么意思？

我在MySQL表中有两列:

bname和count

 bname           count        
----------      ----------


 Blah              2

 Blah              2

 huh               3

 lol               1

 huh               3

 huh               3

我想要这样的东西.我已经创建了count列但我不知道如何像上面的例子一样显示它.count列当前为空.
