ERROR 1267 concat name_const函式



今天朋友他們有一個錯誤，最後是因為：

MySQL> select concat('￥',NAME_CONST('tttt',1234));

ERROR 1267 (HY000): Illegal mix of collations (utf8_general_ci,COERCIBLE) and (latin1_swedish_ci,IMPLICIT) for operation 'concat'

這個類似的錯誤原來也見過：那是因為兩表關聯時，關聯的欄位是有索引的，但是索引不是按的相同的COLLATION，所以出現的問題，修改為一樣之後，即可正常。

又試了一下

MySQL> select concat('a',NAME_CONST('tttt',1234));

+-------------------------------------+

| concat('a',NAME_CONST('tttt',1234)) |

+-------------------------------------+

| a1234                               |

+-------------------------------------+

1 row in set (0.00 sec)

MySQL> select concat('工',NAME_CONST('tttt',1234));

ERROR 1267 (HY000): Illegal mix of collations (utf8_general_ci,COERCIBLE) and (latin1_swedish_ci,IMPLICIT) for operation 'concat'



從這裡看，用漢字的類的就不正常。



MySQL> select COLLATION('工');

+------------------+

| COLLATION('工')  |

+------------------+

| utf8_general_ci  |

+------------------+

1 row in set (0.00 sec)

MySQL> select COLLATION('a');

+-----------------+

| COLLATION('a')  |

+-----------------+

| utf8_general_ci |

+-----------------+

1 row in set (0.00 sec)

MySQL> select COLLATION('￥');

+------------------+

| COLLATION('￥')  |

+------------------+

| utf8_general_ci  |

+------------------+

1 row in set (0.00 sec)

MySQL> select COLLATION(NAME_CONST('tttt',1234));

+------------------------------------+

| COLLATION(NAME_CONST('tttt',1234)) |

+------------------------------------+

| binary                             |

+------------------------------------+

1 row in set (0.00 sec)



有點暈了，前前看 'a','工','￥' 都是一樣的， 漢字的不行。



看看這個函式：

This function is for internal use only，可以寫成別的方式 

比如這裡的 

MySQL> select NAME_CONST('tttt',1234);

+------+

| tttt |

+------+

| 1234 |

+------+

1 row in set (0.00 sec)

可以寫為：

MySQL> select 1234 as 'tttt';

+------+

| tttt |

+------+

| 1234 |

+------+

1 row in set (0.00 sec)

一樣的效果 。



另：

MySQL> select concat('￥',NAME_CONST('tttt','1234'));

+-----------------------------------------+

| concat('￥',NAME_CONST('tttt','1234'))  |

+-----------------------------------------+

| ￥1234                                  |

+-----------------------------------------+

這樣也不會報錯：


不知道開發到底是什麼 意思 ，和開發商量 才好最後約定怎麼搞。
