Oracle SQL to extract Directory from filename

Recently, I had a requirement to extract just the directory name from a file name. The code snipped provided below does just that.

 select substr(:1,1,instr(:1,:2,-1)) FROM DUAL; 

where :1 is the full file name(along with the path)

:2 is the directory separator

For instance,

 select substr('D:\Sample\Mani.txt',1,instr('D:\Sample\Mani.txt','\',-1)) FROM DUAL; 

This code would strip off the file name and return just the directory

 D:\Sample\ 

Have fun. 🙂
