What does the INSTR function return when given two arguments?

The INSTR function is designed to return the numeric position of a substring within a string when provided with two arguments—specifically, the string to search within and the substring to find. This allows users to identify where in the larger string the specified substring first appears, making it especially useful for tasks involving string manipulation in databases or programming contexts.

For instance, if the main string is "NetSuite" and the substring is "Suite," the INSTR function would return the starting position of "Suite" within "NetSuite," which is 4, reflecting its location counting from the beginning of the string. This capability to pinpoint the position helps in various scenarios, such as validating data, parsing information, or performing conditional operations based on the presence of certain text.
