REPEAT function - Amazon Redshift
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Amazon Redshift will no longer support the use of Python UDFs after June 30, 2026. We will start enforcing it in phases. For more information on the details of Python end of life and migration options, see the blog post that was published on June 30, 2025.

Examples

The following example uses data from the CATEGORY table in the TICKIT sample database. For more information, see Sample database.

To repeat the value of the CATID column in the CATEGORY table three times, use the following example.

SELECT catid, REPEAT(catid,3) FROM category ORDER BY 1,2; +-------+--------+ | catid | repeat | +-------+--------+ | 1 | 111 | | 2 | 222 | | 3 | 333 | | 4 | 444 | | 5 | 555 | | 6 | 666 | | 7 | 777 | | 8 | 888 | | 9 | 999 | | 10 | 101010 | | 11 | 111111 | +-------+--------+

The following example demonstrates generating strings up to 16,000,000 bytes:

SELECT LEN(REPEAT('X', 5000000)) AS five_million_bytes, LEN(REPEAT('Y', 16000000)) AS sixteen_million_bytes; five_million_bytes | sixteen_million_bytes ----------+----------- 5000000 | 16000000
