How can I check if an SQL result contains a newline character?

问题

I have a varchar column that contains the string lol\ncats, however, in SQL Management Studio it shows up as lol cats.

How can I check if the \n is there or not?

回答1:

SELECT *
FROM your_table
WHERE your_column LIKE '%' + CHAR(10) + '%'

Or...

SELECT *
FROM your_table
WHERE CHARINDEX(CHAR(10), your_column) > 0

回答2:

Use char(13) for '\r' and char(10) for '\n'

SELECT *
FROM your_table
WHERE your_column LIKE '%' + CHAR(10) + '%'

or

SELECT *
FROM your_table
WHERE your_column LIKE '%' + CHAR(13) + CHAR(10) + '%'

For any fellow MySQL users who end up here:

SELECT *
FROM your_table
WHERE your_column LIKE CONCAT('%', CHAR(10), '%')

For me, the following worked just fine in both MySQL Workbench & HeidiSQL (working with MySQL) without having to use the char() variation of \n:

SELECT * FROM table_name WHERE field_name LIKE '%\n%'

回答5:

SELECT * 
FROM Table 
WHERE PATINDEX('%' + CHAR(13) + CHAR(10) + '%', Column) > 0

回答6:

In Oracle, try the below command

SELECT * FROM table_name WHERE field_name LIKE ('%'||chr(10)||'%');
