Purpose
Function to return the numeric position of the first occurrence of a specified character string in another character string
Syntax
INDEXOF(<expC1>,<expC2>)

Description
The INDEXOF() function returns the numeric position of the first occurrence of the specified character string, <expC2>, in another character string, <expC1>.
A case-sensitive search is performed. Character positions start from 1, if the string <expC2> is not found, INDEXOF() returns 0.
| Parameters | Description |
|---|---|
| <expC1> | The character string to be searched. |
| <expC2> | The character string to search for. |
Example
open database southwind use orders list for indexof(customerid,"AT") = 3
