mysql表结构有 主键 非自增 text longtext类型字段多个 步骤 1、在T-SQL 临时表中处理好所有需要的字段 2、执行openquery语句 字段顺序完全按照mysql字段顺序插入 此时发现错误：Duplicate entry '0' for key 'PRIMARY' 经强哥指点，兑换主键字段和长类型字

mysql表结构有 主键 非自增 text longtext类型字段多个

步骤

1、在T-SQL 临时表中处理好所有需要的字段

2、执行openquery语句 字段顺序完全按照mysql字段顺序插入

此时发现错误：Duplicate entry '0' for key 'PRIMARY'

经强哥指点，兑换主键字段和长类型字段的位置，重新执行openquery语句

此时无错误发生，，但是查看mysql表内数据时发现当初执行openquery语句时第一个字段没有插入成功

究其原因，始终不解，为完成数据导入，只能折中在此基础上进行openquery的更新操作

现希望广大大神们有知其问题所在者，望不吝告知，吾在此拜谢！
