& Operator: Concatenating Strings and Numbers

Article Number:040511

Using the "&" operator, you can concatenate multiple field values.
When concatenating strings and numbers, you must use a half-width "&" operator. You cannot use a "+" operator for this purpose.

Fields That Can Be Concatenated with "&" Operator

When using the "&" operator to concatenate fields, you can specify the following field types for concatenation.

  • Text
  • Number
  • Calculated
  • Radio button
  • Drop-down
  • Date1
  • Time1
  • Date and time1
  • Lookup2
  • Record created by
  • Record updated by
  • Record created datetime1
  • Record updated datetime1

1: Use the DATE_FORMAT function to specify a formula.
2: If the Key Field is a "Link" field or a "Lookup" field (whose Key Field is a "Link" field), that field cannot be referenced by a formula.

This section describes how to concatenate a first name and last name that are entered separately in different fields, using an example of a company directory app.

  1. Click the App Settings icon (the gear-shaped icon at the upper right of the app's "View" screen), then select the Form tab.
    Screenshot: The "App Settings" icon

  2. Place two "Text" fields on the app form. To do so, drag the "Text" field from the list of fields on the left side of the screen and drop it in the area on the right side of the screen. Screenshot: Placing "Text" fields

  3. Open the field settings and change the field name and field code for each field. For the first field, change the field name to "First Name" and the field code "First_Name". For the second field, change the field name to "Last Name" and the field code to "Last_Name". Screenshot: A GIF that shows a field name and field code being changed

  4. On the app form, place a "Text" field to be used for displaying the result of concatenation, then change its field name to "Full Name" and its field code "Full_Name". Screenshot: Placing the field

  5. Open the field settings of the "Full Name" field, select Calculate automatically, and then enter the following formula: First_Name&" "&Last_Name
    A half-width '&' is used for concatenating strings. If you want the result to contain a specific character string or a space, use half-width double quotation marks (""). Screenshot: A formula set in a "Text" field

  6. Click Save on the field setting screen.

  7. Click Save Form on the upper left side of the screen, and then click Update App on the upper right side of the screen. Screenshot: "Update App"

  8. On the confirmation dialog, click Update App.

You have successfully configured a field that concatenates character strings. Screenshot: A formula for concatenating character strings is displayed

Enter values in the "First Name" and "Last Name" fields, then check that the full name automatically appears in the "Full Name" field. Screenshot: Checking that character strings are successfully concatenated

Tips: If there are fields with empty values

Empty fields are concatenated as empty strings.
For example, assume that a field has the following formula set: State/Province&City&Street&Building_Name&" "&Floor. In this case, even when the "Building Name" field is empty, the values of the other fields are concatenated. Screenshot: The result of concatenation when there is a field with an empty value
