About the leftmost index prefixes using nounique index
hello, I want to know about the leftmost index prefixes using nounique index/ About the composite index using primary key, in the reference 7.4.5, I can understand the following: -- MySQL can see that if a column is a leftmost prefix of the primary key, I can use it as though it were a separate index. I don't need to define a second index on the column alone. On the other hand, if a column is not a leftmost, I need to define a second index . -- Is the above content legal about the leftmost index prefixes using nounique index?
The number of left join in one SQL statement.
Hello, my name is Takanobu Kawabe. I have some questions about left join SQL statement. I want to join some tables, and using left join statement . the system is the following. I use two machines. I created the same databases and tables on both machines. OS ： Debian Linux the newest stable 3.1 Server ： Apache 2.0 MySQL ： 5.0.20 PHP ： 5.1.4 OS ： WindowsXP Server ： Apache2.0 MySQL ： 5.0.19 PHP ： 5.1.2 And I considered the following SQL statement to select some columns from some tables using left join. SELECT `MST`.`no`, `MST`.`denhyono`, `GUS`.`TANI` AS `GUS`, `SUIDO`.`TANI` AS `SUIDO`, `DENKI`.`TANI` AS `DENKI`, `SYOKUIN1`.`SYOKUINNAME` AS `SYOKUIN1`, `SYOKUIN2`.`SYOKUINNAME` AS `SYOKUIN2`, `TANTOSYA`.`TANTOSYANAME` AS `TANTOSYA` FROM `MST` Left Join `TANIMST` AS `GUS` ON `MST`.`GUSno` = `GUS`.`no` Left Join `TANIMST` AS `SUIDO` ON `MST`.`SUIDOno` = `SUIDO`.`no` Left Join `TANIMST` AS `DENKI` ON `MST`.`DENKIno` = `DENKI`.`no` Left Join `SYOKUINMST` AS `SYOKUIN1` ON `MST`.`SYOKUINno1` = `SYOKUIN1`.`no` Left Join `SYOKUINMST` AS `SYOKUIN2` ON `MST`.`SYOKUINno2` = `SYOKUIN2`.`no` Left Join `SYOKUINMST` AS `TANTOSYA` ON `MST`.`TANTOSYAno` = `TANTOSYA`.`no`; - I tried this statement without error. But Ihave some questions. 1.How many left join keywords can I use in one SQL statement if there are 5000 datas in one table? 2. when some customers use this query, can they read this query exactly? 3. Will the above query speed become slowly if there are 5000 datas in one table? Will the processing efficiency improve if I use multiple SQL statement? 4.Is there any other effective SQL statement I can get better processing efficiency?
