Looking for a string within a string
If you need to check whether an expression exists within a string, you can use the CHARINDEX() function. This function returns the position of the expression you are searching within the string.
The syntax is:
CHARINDEX(expression_to_find, expression_to_search [, start_location])
In this exercise, you are going to use the voters table to search for information about the voters whose names meet several conditions.
