Is there any function to find the position of a specific value in a field.. Lets say i have a field customer name. I have ABC customer in it.. I want to know the occurance of the value 'ABC' of it in the field.
Position of a substring. This function gives the starting position of the n:th occurrence of substring s2 in string s1. If n is omitted, the first occurrence is assumed. If n is negative, the search is made starting from the end of string s1. The result is an integer. The positions in the string are numbered from 1 and up.
Examples:
index( 'abcdefg', 'cd' ) returns 3
index( 'abcdabcd', 'b', 2 ) returns 6
index( 'abcdabcd', 'b', -2 ) returns 2
left( Date, index( Date,'-') -1 ) where Date = 1997-07-14 returns 1997
mid( Date, index( Date, '-', 2 ) -2, 2 ) where Date = 1997-07-14 returns 07
