Question

navicat导出数据表的时候有个“添加”选项作用是什么？如下图所示：

Answer 1

is to add exported data to the end of an existing file.

If the subject has programming experience, it can be used as an output stream append.

Note: When you select the same file when exporting, you may be prompted that the file already exists. Ignore that prompt and continue to select the existing file. If 添加 is checked, it will be added to the original file, otherwise it will be overwritten. Change the file!
