So basically, I want everything after
and before

How can I solve it?


If you want to get this out of your table using SQL, take a look at the following functions that will help you: SUBSTRING and CHARINDEX. You can use those to trim your entries.

A possible query will look like this (where col is the name of the column that contains your image directories:

SELECT SUBSTRING(col, LEN(SUBSTRING(col, 0, LEN(col) - CHARINDEX ('/', col))) + 1, LEN(col) - LEN(SUBSTRING(col, 0, LEN(col) - CHARINDEX ('/', col))) - LEN(SUBSTRING(col, CHARINDEX ('.', col), LEN(col))));

Bit of an ugly beast. It also depends on the standard format of 'dir/name.ext'.

This one (inspired by praveen) is more generic and deals with extensions of different length:

SELECT SUBSTRING(col, LEN(LEFT(col, CHARINDEX ('/', col))) + 1, LEN(col) - LEN(LEFT(col, CHARINDEX ('/', col))) - LEN(RIGHT(col, LEN(col) - CHARINDEX ('.', col))) - 1);
