MySQL String Last Index Of in a URL?
To get the last index, use the SUBSTRING_INDEX() function from MySQL. The syntax is as follows −
SELECT yourColumnName1,...N,SUBSTRING_INDEX(yourColumnName,’yourDelimiter’,-1)as anyVariableName from yourTableName;
To understand the above syntax, let us create a table. The query to create a table is as follows
mysql> create table LastIndexString -> ( -> Id int, -> yourURL text -> ); Query OK, 0 rows affected (0.89 sec)
Insert some records in the table using INSERT command. The query is as follows −
mysql> insert into LastIndexString values(1,'https −//www.example.com/home.html'); Query OK, 1 row affected (0.26 sec) mysql> insert into LastIndexString values(2,'https −//exampledemo.example.com/index.jsp'); Query OK, 1 row affected (0.18 sec) mysql> insert into LastIndexString values(3,'https −//www.example.com/question/LastString'); Query OK, 1 row affected (0.18 sec)
Display all records from the table using SELECT statement. The query is as follows −
mysql> select *from LastIndexString;
The following is the output displaying URL string −
+------+---------------------------------------------+ | Id | yourURL | +------+---------------------------------------------+ | 1 | https −//www.example.com/home.html | | 2 | https −//exampledemo.example.com/index.jsp | | 3 | https −//www.example.com/question/LastString| +------+---------------------------------------------+ 3 rows in set (0.00 sec)
Here is the query to get the last index string from a URL string −
mysql> select Id, substring_index(yourURL,'/',-1) as LastStringFromURL from LastIndexString;
The following is the output displaying the part of the URL −
+------+-------------------+ | Id | LastStringFromURL | +------+-------------------+ | 1 | home.html | | 2 | index.jsp | | 3 | LastString | +------+-------------------+ 3 rows in set (0.00 sec)
