如何使用mysql中的vary选项将多条记录从一个表中的某一列复制到一列中的另一个表中

如何使用SQL命令在mysql中使用vary选项从表中的某一列复制多条记录并插入以更新列中的另一个表

列：“targetCategory”条件所有记录都包含Top/name\u test2、Top/name\u test2/%

列“标题”，“父主题”引用数据 注意：数据具有根差异，不导入示例：Top/name\u test752

从“parentTopic”goo到“parentTopic”的数据
我需要在“displayName”列中插入新数据，该列将为“Nuul”
我需要在“说明”列中插入新数据，并将其视为“主题短”
我需要在“displayName”列中插入新数据，该列将为“Nuul”
我需要在“lastUpdate”列中插入新数据，而不是“数据时间插入”
我需要在“displayName”列中插入新数据，该列可能为“0”
将其列targetCategory数据设置为Top/name_test2和Top/name_test2/%

不完全清楚您想要什么，但您可以与适当的一起使用。例如，要从

列2

中删除所有内容，直到第一个冒号：

INSERT INTO table_exemple3 (column4, column5, column6)
SELECT column1, SUBSTRING(column2, LOCATE(':', column2) + 1), column3
FROM   table_exemple2

---

请参阅。

您如何确定希望复制到

表例2

中的

表例1

中的哪些记录？您如何确定带有

表例2.id=6

的新记录的值，该记录似乎与

表例1

中的任何原始记录几乎没有相似之处？如果根不同的示例Top/name\u test50已经不需要了，我不想创建重复的记录

6

has

topic='Top/name\u test2/32'

和

topicShort='32'

；根据您的映射，这些值应该分别来自

targetCategory

和

title

，但没有任何记录在

表中的示例1

中有这些值：）是的，这是我的错，所以你现在明白了，好吧，你有解决方案了吗？你看到我下面答案中的SQLFIDLE链接了吗？@olariuromevicentiu:你想要类似的东西吗？
