Finding pattern in strings

[Srinivas reddy Guda]

Hello Friends,

How to find the pattern in strings.

Example: In string "MATHEMATICS", i want to know the first occurrence of
"MAT".

Is there any standard function is available or we have to write our own
code for this?

I am looking like function in oracle INSTR.

Thanks in Advance,
Srinivas.
