SQL Replace function in nth occurrence

The REPLACE function in SQL is used to replace all occurrences of a specified string in a supplied string with another one.

Sometimes, we may need to change only a single instance of the string rather than all occurrences.

To do this, we may use the following SQL procedure to replace the nth occurrence of a string:

sql replace nth occurrence: Setup

We must replace the following in the above SQL statement:

• column name should be substituted with the name of the column containing the string to be replaced.
• Replace the string with search string.
• Replace string is the string that will be used to replace the nth occurrence of the search string.
• n with the occurrence number to be replaced.

The CHARINDEX function is used to locate the nth occurrence of a search string. After that, the SUBSTRING function is used to extract the bits of the original text that come before and after the nth occurrence of the search phrase.

Ultimately, to get the desired output, the CONCAT function is used to concatenate these sections with the replace string.

It is preferable to use the STUFF and CHARINDEX methods to replace the first occurence of a character. STUFF inserts one string into another.

It deletes a defined number of characters from the first string at the beginning and then inserts the second string into the first string at the beginning.

DECLARE @str varchar(100) = '^1402 WSN NIAMLAB^teertS htimS 005' SELECT STUFF(@str, CHARINDEX('^', @str), 1, '&')

It’s worth noting that we could also use STUFF in a query like this:

SELECT STUFF(, CHARINDEX('^', ), 1, '&') FROM yourtable
