Limit SQL query result in MySQL -


मैं MySQL में लाने वाली पंक्तियों की मात्रा को सीमित करना चाहूंगा

ex:

  • पहली क्वेरी मैं केवल पहले 10,000 रिकॉर्ड प्राप्त करना चाहूंगा
  • दूसरी क्वेरी मैं चाहूंगा

आदि

शब्द से केवल रिकॉर्वर प्राप्त करें आप "पृष्ठ पर अंक लगाना" की तलाश कर रहे हैं। दुर्भाग्य से, यह एसक्यूएल इंजन के आधार पर अलग ढंग से किया जाता है।

एमएस SQL ​​सर्वर के लिए, यह देखें।

चूंकि आपने मायएसक्यूएल का उल्लेख किया है, यह वास्तव में बहुत सरल है: 

 <कोड> सेलेक्ट [कॉलम] से [एक टेबल] LIMIT 10000 SELECT [कॉलम] से [एक टेबल] LIMIT 10000 OFFSET 10000

पहला वक्तव्य 1-10,000 परिणामों को प्राप्त करता है, और दूसरा कथन परिणाम 10,001-20,000 तक लाता है।

How can I use the Pageinization Assistant in KPHPH to set more than one result on the same page? They will do the page independently Edit: I have found a reason why it can not do this because because the page will get its URL from the assistant controller / verb and after that Finally add its parameters. If it pulls the URL from the address bar, it has its own unique variable and then a straw_rele is used to navigate to the next one if you have already placed the page, or if it is not present in it Now, I'm thinking of re-writing assistant to support this feature to support this feature, but I'm not sure if I need it or if they are already I support it and I am doing it wrong Here's my solution in your controller: function index () {// your default model is $ $ this- & gt; Set ('model1', $ this- & gt; paginated)); // Endorsement for Model 2- $ this- & gt; Set ('Model2', $ this- & gt; Paginated ('Model2')); } In your ...

I'm trying to display the file name in a listbox, taken from a special directory.
