MySQL truncate text with ellipsis
Question
Suppose I have a MySQL table of one column: "Message". It is of type TEXT. I now want to query all rows, but the text can be large (not extremely large but large) and I only want to get a summary of them. For example the result can be populated into a list.
Is there a way to trim the text to a specific length (say, 10 characters), and add ellipsis if the text is trimmed?
For example:
Message
-----------
12345678901234
1234567890
12345
12345678901
Query result:
1234567...
1234567890
12345
1234567...
Thanks!
Solution
select case when length(message) > 7
then concat(substring(message, 1, 7), '...')
else message end as adapted_message
from ...
to test/confirm:
SELECT CASE WHEN LENGTH('1234567890') > 7
THEN CONCAT(SUBSTRING('1234567890', 1, 7), '...')
ELSE '1234567890' END AS adapted_message
UNION
SELECT CASE WHEN LENGTH('12345') > 7
THEN CONCAT(SUBSTRING('12345', 1, 7), '...')
ELSE '12345' END AS adapted_message
OTHER TIPS
or...
SELECT CONCAT(LEFT(message, 7), IF(LENGTH(message)>7, "…", ""))
FROM table
Here's a simple one line solution:
IF(CHAR_LENGTH(message) > 10, CONCAT(LEFT(message, 7),"..."), message)
Have a look at the MySQL string functions, documented here. You should be able to use some combination of substring
and concat
to achieve your desired behaviour.
