为什么这样描述的比方是一片 my子的 que子,什么是回报?
原标题:Why does this string comparision mysql query return nothing?

I execute the following:

SELECT url FROM mytable WHERE 1

结果:http://www.ciao.es/Epson_Stylus_S22_2007613

到现在为止......但当我这样做时:

SELECT * FROM mytable WHERE url =  http://www.ciao.es/Epson_Stylus_S22__2007613 

!

I tried using LIKE, changing the quotes, etc... what am I doing wrong?

最佳回答

You are having in your table field url .So if you are querying you will get output like this: http://www.ciao.es/Epson_Stylus_S22__2007613 (with in single quote) SO Write in this way:

SELECT * FROM mytable WHERE url = " http://www.ciao.es/Epson_Stylus_S22__2007613 "

或从表格中删除单一报价。
