Result Type

Arguments

The following table describes the arguments for the function.

Argument

Description

string1

Specifies the string that is to be searched. The value can be a string literal, or a field name, or an expression that returns a string.

string2

Specifies the string that is to be searched for. The value can be a string literal, or a field name, or an expression that returns a string.

NOTE: The search for a string is case-sensitive.

(Optional) An integer that specifies the start point in string1.

Examples

The following example returns the value 9:

InStr('john.doe@company.com','@')

The following example shows how the InStr function can be used in a workflow rule condition. In the workflow rule condition, the InStr function is used to determine if a specified string appears in a field on the record. If the string is found in the field, then the actions specified on the workflow rule are performed. In this example, the InStr function determines if the Subject field in a record contains the word REVIEW. The action on the workflow rule is performed only if the Subject field contains the word REVIEW in uppercase letters.

InStr([<Subject>], 'REVIEW') > 0
