Replace Numbers in DB2 String

In IBM Db2 database, you can use the REGEXP_REPLACE function to replace all numbers in a string. This function allows you to use regular expressions to match the content to be replaced.

Here is an example usage: Suppose we have a string containing numbers ‘abc123def456ghi’, and we want to replace all the numbers with a specific character (such as a space):

SELECT REGEXP_REPLACE('abc123def456ghi', '[0-9]', ' ') AS replaced_string FROM sysibm.sysdummy1;

In the example above, ‘[0-9]’ is a regular expression pattern that matches all numbers. ‘ ‘ is the character to be replaced with. After executing the SQL query above, the result will return as ‘abc def ghi’, which means all the numbers in the original string are replaced with blank spaces.
