mysql limit 用法詳解（修正版）

在google中輸入"mysql limit"，得到的前兩條記錄內容是雷同的，其中有這樣一段

“//為了檢索從某一個位移量到記錄集的結束所有的記錄行，可以指定第二個參數為 -1： 

mysql> SELECT * FROM table LIMIT 95,-1; // 檢索記錄行 96-last. ”

這段其實是在誤人子弟，來看看mysql的官方文檔：http://dev.mysql.com/doc/refman/6.0/en/select.html

內容摘錄如下：

The LIMIT clause can be used to constrain the number of rows returned by the SELECT statement. LIMIT takes one or two numeric arguments, which must both be non-negative integer constants (except when using prepared statements).

With two arguments, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return. The offset of the initial row is 0 (not 1):

SELECT * FROM tbl LIMIT 5,10;  # Retrieve rows 6-15

To retrieve all rows from a certain offset up to the end of the result set, you can use some large number for the second parameter. This statement retrieves all rows from the 96th row to the last:

SELECT * FROM tbl LIMIT 95,18446744073709551615;

With one argument, the value specifies the number of rows to return from the beginning of the result set:

SELECT * FROM tbl LIMIT 5;     # Retrieve first 5 rows

In other words, LIMIT row_count is equivalent to LIMIT 0, row_count.
