Sequence function in Power Apps
Generate a table of sequential numbers.
Description
The Sequence function generates a single column table of sequential numbers, such as 1, 2, 3. The name of the column is Value. Sequence( 4 )
is equivalent to [1,2,3,4]
.
Use Sequence with the ForAll function to iterate a specific number of times. For example, the following formula adds 10 random numbers to the collection MyRandomNumbers:
ForAll( Sequence( 10 ), Collect( MyRandomNumbers, Rand() ) )
ForAll can also be used to transform the value into other data types and return a new table. For example, the following formula returns a table of the next 10 days:
ForAll( Sequence( 10 ), DateAdd( Today(), Value, Days ) )
The number of records to generate is rounded down to the nearest whole number and must be in the range 0 to 50,000. Generating a table with zero records results in an empty table.
Note
Sequence is limited to 50,000 records.
Syntax
Sequence( Records [, Start [, Step ] ] )
- Records – Required. The number of records to create. Must be in the range 0 to 50,000.
- Start – Optional. The starting number for the sequence. Default is 1.
- Step – Optional. The increment for each successive number in the sequence. Step can be negative to count down from the Start. Default is 1.
Examples
Basic usage
Formula | Description | Result |
---|---|---|
Sequence( 4 ) | Generates a 4 record table starting at the default 1 and incrementing by the default 1. | |
Sequence( 4, 24 ) | Generates a 4 record table starting at 24 and incrementing by the default 1. | |
Sequence( 4, 4, -1 ) | Generates a 4 record table starting at 4 and incrementing by -1, effectively counting backward. | |
Sequence( 4, -100, 0.5 ) | Generates a 4 record table starting at -100 and incrementing by 0.5. | |
Sequence( 0.9 ) | Generates an empty table as the count rounds down to 0. | |
ForAll( Sequence( 4 ), Rand() ) | Generates a 4 record table of random numbers. | Actual numbers will vary. |
Concat( Sequence( 5 ), Text( Value ) & " " ) |
Generates a string of numbers from 1 to 5. | "1 2 3 4 5 " |
