错误代码1093：Sql语法错误

Question

我有以下sql。

update voting_table
Set VOTING_STATUS = 1
where  CE_ID = 15813 

and

VOTING_PK = 
(SELECT VOTING_PK FROM voting_table
ORDER BY VOTING_PK DESC
LIMIT 1) ;

但编辑器向我显示以下错误：

Error code 1093, SQL state HY000: You can't specify target table 'voting_table' for update in FROM clause

如何克服错误？请帮我 。

Answer 1

我认为这些SQL对您有所帮助。

update voting_table as table_1, (SELECT VOTING_PK FROM voting_table ORDER BY VOTING_PK DESC LIMIT 1) as table_2  
where table_1.VOTING_PK = table_2.VOTING_PK and CE_ID = 15813 
Set VOTING_STATUS = 1

谢谢。
