It calls the EnumFields procedure, which you can find in the SELECT statement example. This example returns a list of employees whose names begin with the letters A through D. The following table shows how you can use Like to test expressions for different patterns. The following example returns data that begins with the letter P followed by any letter between A and F and three digits: Like "P#" In a parameter query, you can prompt the user for a pattern to search for. ![]() For example, if you enter Like "C*" in an SQL query, the query returns all field values beginning with the letter C.
