我有一份PHP书,该书将一只 c子输入MySQL数据库。 进口品使用该法典线进行罚款

$query = "insert into $databasetable values( $linemysql );";

唯一的问题是,在我试图进口另一只手脚,重复书写错误。 如果存在这种文字,我如何调整这一文字,以弥补重复?

最佳回答

<编码> INSERT IGNORE如果能形成一个重复的钥匙,就打上了字。 然而,它也将忽视(而不是产生错误)试图将<条码>NUL插入的栏目中的其他一些情况。

如果你只是想忽略重复,但又再插入错误,则使用<代码>。 INSERT ... ON DUPLICATE KEY UPDATE. 这将更新带有重复钥匙的行文,尽管有某些业绩成本。

问题回答

如果你利用我方设法:

$query = "insert ignore into $databasetable values( $linemysql );";
