Microsoft SQL Server Replicate


Example

Repeats a string value a specified number of times.

Parameters:

  1. string expression. String expression can be a character string or binary data.
  2. integer expression. Any integer type, including bigint. If negative, null is returned. If 0, an empty string is returned.
SELECT REPLICATE('a', -1)  -- Returns NULL

SELECT REPLICATE('a', 0)  -- Returns ''

SELECT REPLICATE('a', 5)  -- Returns 'aaaaa'

SELECT REPLICATE('Abc', 3) -- Returns 'AbcAbcAbc'

Note: If string expression is not of type varchar(max) or nvarchar(max), the return value will not exceed 8000 chars. Replicate will stop before adding the string that will cause the return value to exceed that limit:

SELECT LEN(REPLICATE('a b c d e f g h i j k l', 350)) -- Returns 7981

SELECT LEN(REPLICATE(cast('a b c d e f g h i j k l' as varchar(max)), 350)) -- Returns 8050
