MySQL query to add dots if string has more than 10 words?

For this, use CASE statement. Let us first create a table −

mysql> create table DemoTable
-> (
-> Title text
-> );
Query OK, 0 rows affected (0.61 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable values('My name is John and this is my first tutorial on MySQL');
Query OK, 1 row affected (0.11 sec)

mysql> insert into DemoTable values('This is Carol and I work on MongoDB');
Query OK, 1 row affected (0.19 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable;

Output

This will produce the following output −

+--------------------------------------------------------+
| Title                                                  |
+--------------------------------------------------------+
| My name is John and this is my first tutorial on MySQL |
| This is Carol and I work on MongoDB                    |
+--------------------------------------------------------+
2 rows in set (0.00 sec)

Following is the query to add dots if string has more than 10 words −

mysql> select (case when substring_index(tbl.Title, ' ', 10) = tbl.Title then tbl.Title
-> else concat(substring_index(tbl.Title, ' ', 10), '....................')
-> end) AS AddDots
-> from DemoTable tbl;

Output

This will produce the following output −

+-------------------------------------------------------------------+
| AddDots                                                           |
+-------------------------------------------------------------------+
| My name is John and this is my first tutorial.................... |
| This is Carol and I work on MongoDB                               |
+-------------------------------------------------------------------+
