Setting Title Field

If you want to display multiple fields in the Title Field, you can use the "&" operator in the Text field to concatenate strings.
You can also use the DATE_FORMAT function to concatenate values of the Date field or the Time field with a string.
For example, you can concatenate customer name and the value of the Date field, and use that for the Title Field.

& Operator: Concatenating Strings and Numbers
DATE_FORMAT Function: Specifying the Display Format of Date and Time
