mysql - 插入 withy 选择：！#1062 - 键 'cry_id' 的重复条目 '222-104276'

Question

我有一个下表：

dct_cry_id............cry_id............dct_id............分类............dct_connection_id（.. .) 71.......................13............104276............ .....70..................0 2110........29....... ........104276............7............0 2111...... ............37............104276............8...... ......0 2112............38............104276...... ............6............0（......）591............ ....13........154614..................540........0 2090.. .....................36........154614..................46。 ......................0 2091......................30............ 154614.......................2................0 (...)

我使用以下查询

I use following query
INSERT INTO mytabletest1 (cry_id,`dct_id`)
-- VALUES (222)
SELECT  
222, `dct_id`

FROM `mytabletest1`
WHERE `cry_id`
NOT IN 
(
112, 115, 116, 117, 118,
973, 974, 975, 976, 977,
8 
)

不幸的是，我有以下警告/错误消息：

“！#1062 - 键‘cry_id’的重复条目‘222-104276’”

为什么我有这个消息？

在此之后，我检查了我的表，我的查询有效 ：dct_cry_id............cry_id............dct_id............classify ........dct_connection_id (...) 71.......................13.......... ..104276........70........0 2110...... ......29............104276............7 0 2111............37............104276............ ..8......................0 2112............38....... .....104276............6............0 153876............ ............222............104276............0...... .0 (...) 591......................13............154614...... .........540.............0 2090........36.. ............154614............46............0 2091............ ......................30............154614............2....... ...........0 15870......................222............154614............0 .............0 (...)

Answer 1

您的查询将返回键 '222-104276' 4 次。记录插入一次，第二次插入时引发错误。
