MySQL Query太大了？ 导致无响应的控制台

Question

As I was trying to add a quote (via a PHP/HTML form) to my site that was particularly long, I noticed that the longer quotes did not get added via the MySQL query. The shorter ones got added just fine.

This is not a problem with the length of the columns in my table, the quotes are most definitely shorter than the limit (which is VARCHAR(600)).

When I try to manually enter the quotes into the database from the MySQL command line, hitting enter after entering the query properly does not result in a new prompt (it goes to the next line of the query instead). The query never executes.

The only way I can get to a new prompt is to force exit out of the MySQL command line and re-opening it. Anyone know why this is happening?

EDIT : Here is my query. The first 3 values are irrelevant, I won't confuse anyone by explaining them. The last 2 are the source and the quote.

EDIT2 : MySQL version is 5.5.8

THE QUERY THAT DOES NOT WORK

INSERT INTO quotes VALUES(NULL, 2, 20, 'http://www.mlb.com/news/article.jsp?ymd=20091104&content_id=7620238&vkey=news_nyy&fext=.jsp&c_id=nyy', 'He's the reason we're here. First of all, we wouldn't be in this stadium if it wasn't for him. We wouldn't have this group together if it wasn't for him. It's a special moment. We all wanted to win it for him.');

EXAMPLE OF A QUERY THAT WORKS

INSERT INTO quotes VALUES(NULL, 2, 20, 'http://www.mlb.com/news/article.jsp?ymd=20091104&content_id=7620238&vkey=news_nyy&fext=.jsp&c_id=nyy', 'I guess you could say that this is the best moment of my life right now," Matsui said. "If I were to look back, yes, this would be the best.');

To those downvoting, mind telling me why?

FINAL EDIT Got it... it's because of the single quotes in my quote. Thank you.

Answer 1

The following things could cause the MySQL console to think that you have not yet finished your query, and there is more to enter:

• An unclosed quote, or backtick.
  • Usually due to the fact that you didn't escape a quote by doing \\' (for single quotes) or \\" (for double quotes).
• No semi-colon at the end of the query.

Make sure you don't have either of those problems and the query should run.

Edit following poster's edit: Yeah, looking at your query, you need to escape quotes by replacing ' with \\' whenever it is inside an item of data. PHP has a function to escape for you which is mysql_real_escape_string() . You could also use prepared statements, which prevents this problem. See this question for more information.

Answer 2

这是非常明显的，我的朋友......你在最后一个字符串中有单引号，而使用那些作为你的字符串边界...

Answer 3

When in the MySQL console, make sure you add a semicolon (;) to the end of the query. Otherwise, it will expect more to the query.

Answer 4

You've got single quotes inside your string, which is encapsulated in single quotes.

You should be escaping your strings with mysql_real_escape_string (or something similar, like PDO): http://php.net/manual/en/function.mysql-real-escape-string.php

Answer 5

听起来你没有正确地转义引号中的'或'字符。查找任何'或'或\\字符并在它们之前添加\\。

Answer 6

You post no PHP code but your SQL suggests that you are omitting two basic steps:

1. Use prepared statements to inject data into your queries (or proper escaping functions)
2. Test the result of your DB calls and print/log error messages.
