Sql 导入到 Excel 工具

Sql 导入到 Excel 工具

这个VBA宏的步骤如下：

1. 通过文件对话框选择SQL文件。
2. 读取文件内容。
3. 解析文件中的每一行，如果包含“insert into”，则提取表名。
4. 检查是否已经存在以表名命名的工作表，如果不存在则创建新的工作表。
5. 将数据插入到相应的工作表中。

Tip：因为 sql 文本 大小写等问题实际比较复杂，所以本例谨慎使用。
一些意外的情况，比如字段包含一些 ) values 之类的，主要是定位问题，再就是值的长度，万一值里面也有,逗号，再就是空格等问题；
用python应该会好处理些；
以下VBA脚本经供参考；可以自行绑定按钮；

针对这样式的：

insert into aaa (aa,bb,cc) values ('2','','3aa');
insert into aaa (aa,bb,cc) values ('1',null,'');
