从 excel 文件列表中删除具有特定值的 SQL 行

Question

I want to make an SQL query. I want to delete all the rows that include a specific email address. The string with the email addresses will load from an excel file. Instead of having to write the emails one by one like shown below:

DELETE FROM Table1
WHERE email ('aaa@aaa.com', 'bbb@bbb.com')

I would like to load the string using the excel file (.xlsx, .csv or any other filetype) where the email addresses are written.

LOAD * FROM excelfile.xlsx

or even load cell values from a specific column

Answer 1

If you need to do this operation once, you can write a query in EXCEL, multiply it to all your lines and then copy-paste and execute your query.

Write EXCEL formula in the free row:

="DELETE FROM TABLE1 WHERE email  = '"&RC[-1]&"'"

Drag it to all your data, and you will get SQL query:

DELETE FROM TABLE1 WHERE email  = 'aaa@aaa.com' 
DELETE FROM TABLE1 WHERE email  = 'bbb@bbb.com'

Then copy/paste and execute your query
