记事本++中的正则表达式：查找所有“ INSERT INTO…;” 查询

Question

I have a big sql file that contains a lot of 'create table ...' and 'insert ...' queries. Now I want to eliminate all the 'insert' queries from the file. The insert queries are somewhat like:

INSERT INTO 'some_table' (col1, col2, col3) values
('val11','val12','val13'),
('val21','val22','val23'),
('val31','val32','val33');

Using Notepad++ I want to find and delete all these 'INSERT' queries using regular expression.

When I tried finding with the regex INSERT INTO((.*\\r\\n)*) then it selects from the start of the first INSERT query till the end of the file. Now when I place the semicolon after this reqex ( INSERT INTO((.*\\r\\n)*); ), it finds nothing? How can I terminate the regex search with semicolons ( ; )?

Answer 1

The semicolon falls before the end of the line, and that is where it needs to be in your regex.

INSERT INTO(([^;]*\r\n)*(.*;(\r\n|$)))

A more reliable approach is:

INSERT INTO[\s\S]*?(?<=;)\s*$

which allows you to have semicolon literals in your query.

Answer 2

INSERT INTO.*?;

choose the match newline option

---

You were matching it greedily( .* )...use lazy quatifier( .*? )

No need of \\r\\n ...
