mysqli_multi_query何时停止执行? [英] When does mysqli_multi_query stop execution?
问题描述
建议我们使用以下3个MySQL命令编写此SQL文本:
Suggested that we have this SQL text with 3 MySQL commands:
show tables;
some nonesense command which makes error;
show tables;
第一个和第三个SQL有效，第二个无效.因此，当将此SQL文本传递给mysqli_multi_query时，MySQL会在第二个命令(错误一个)停止执行吗，还是试图一直执行到最后一个命令?如果在错误一之后的那些命令依赖于错误一，那么这很危险.
The first and third SQL are valid, the second isn't. So, when passing this SQL text to mysqli_multi_query, does MySQL stop execution at the second command (error one) or it tries to go on until the last command? Coz it is dangerous if those commands after the error one relies on the error one.
推荐答案
否，如果一个查询失败，则其余查询将不执行.请参阅mysqli_multi_query的文档中的此注释. ，这很清楚，也展示了一种检查错误的方法.
No, if one query fails the rest will not be executed. See this comment over at the documentation for mysqli_multi_query, which makes this clear and also showcases one way to check for errors.
