Finding a line break in a text string in a SQL tab

问题:

I was trying to find line breaks and carriage returns in a column in a SQL table and I am not sure about the syntax.

I tried:

SELECT foo FROM test
WHERE foo LIKE CHAR(10)

I didn't get any results even though I know that the table should return results. What am I doing wrong?

回答1:

SELECT foo FROM test WHERE foo LIKE '%' + CHAR(10) + '%'

Edit: to find all various types of line endings you should probably just check both:

SELECT foo FROM test WHERE foo LIKE '%' + CHAR(10) + '%'
                        OR foo LIKE '%' + CHAR(13) + '%'

回答2:

SELECT foo FROM Table WHERE foo LIKE '%' + CHAR(13)+CHAR(10) + '%'

回答3:

Try

  SELECT foo FROM test WHERE foo LIKE '%'+ CHAR(10)+'%'

回答4:

Try

SELECT foo FROM test WHERE foo LIKE CONCAT('%', CHAR(10), '%')
