MySQL truncate text with ellipsis?
You can truncate the text with ellipsis using LENGTH() with CASE statement. If your length is greater than 7 then truncate the text and add some number otherwise print the number as it is.
To understand the above syntax, let us create a table. The query to create a table is as follows:
mysql> create table TruncateText -> ( -> Id int NOT NULL AUTO_INCREMENT, -> Number longtext, -> PRIMARY KEY(Id) -> ); Query OK, 0 rows affected (0.66 sec)
Insert some records in the table using insert command. The query is as follows:
mysql> insert into TruncateText(Number) values('64575868667687');
Query OK, 1 row affected (0.11 sec)
mysql> insert into TruncateText(Number) values('7654332');
Query OK, 1 row affected (0.17 sec)
mysql> insert into TruncateText(Number) values('25434656');
Query OK, 1 row affected (0.19 sec)
mysql> insert into TruncateText(Number) values('6457586');
Query OK, 1 row affected (0.17 sec)
mysql> insert into TruncateText(Number) values('958567686868675757574');
Query OK, 1 row affected (0.13 sec)
mysql> insert into TruncateText(Number) values('374785868968787');
Query OK, 1 row affected (0.21 sec)
mysql> insert into TruncateText(Number) values('58969678685858585858585858585');
Query OK, 1 row affected (0.14 sec)Display all records from the table using select statement. The query is as follows:
mysql> select *from TruncateText;
The following is the output:
+----+-------------------------------+ | Id | Number | +----+-------------------------------+ | 1 | 64575868667687 | | 2 | 7654332 | | 3 | 25434656 | | 4 | 6457586 | | 5 | 958567686868675757574 | | 6 | 374785868968787 | | 7 | 58969678685858585858585858585 | +----+-------------------------------+ 7 rows in set (0.00 sec)
In the above sample output, we have some numbers whose length is greater than 7. If the length is greater than 7 then we need to append a numeric number after 7th digit. If the length is 7 or equal to 7 then there is no need to append the numeric number.
The query is as follows:
mysql> SELECT *, CASE WHEN LENGTH(Number) > 7 -> THEN CONCAT(SUBSTRING(Number, 1, 7), '99999999') -> ELSE Number END AS AddNumber -> FROM TruncateText;
The following is the output:
+----+-------------------------------+-----------------+ | Id | Number | AddNumber | +----+-------------------------------+-----------------+ | 1 | 64575868667687 | 645758699999999 | | 2 | 7654332 | 7654332 | | 3 | 25434656 | 254346599999999 | | 4 | 6457586 | 6457586 | | 5 | 958567686868675757574 | 958567699999999 | | 6 | 374785868968787 | 374785899999999 | | 7 | 58969678685858585858585858585 | 589696799999999 | +----+-------------------------------+-----------------+ 7 rows in set (0.00 sec)
Look at the above sample output. If the number is greater than 7, then we have truncated all the values from the number and added a number '99999999' after 7th digit.
