1/25/2024 0 Comments Mysql concat comma separated![]() Or 1 and 2 and 4.Is there a nice way to do this with a SELECT? I am using PHP but I'd really like to handle this in the query so that I know the number of rows returned from the start (rather than grabbing all of them, exploding the string or substring searching it, and then deciding from there). This will output an empty string if either of the columns are null or empty. Yes, comma separated is always desirable, but SQL isn't good at it. For example if 1 and 9 are in the string. Can anyone please advise how I should change the code It worked without the ', ' in the middle of the query, but didn't give a comma. ('Those operations' being parsing a comma-delimited string of integer values into a list of integers.) For a pure SQL answer, the best you could hope for would be a stored function that takes a string and uses procedural logic to parse the values out of the string and then sum them. USE AdventureWorks2022 GO SELECT STRINGAGG(CONVERT(NVARCHAR(max), ISNULL(FirstName,'N/A')), ',') AS csv FROM Person.Person GO Here is the result set. The following example replaces null values with 'N/A' and returns the names separated by commas in a single result cell. ![]() I tried to do so using this code, but it didn't work. Generate list of names separated with comma without NULL values. ![]() It will extract parts of the number and use the CONCAT to join the specific parts together. I managed to concatenate them, but I need to separate them with a comma. For example, the following query shows all dynamic. I have sort of a weird problem:There is a table that has a column that contains what essentially is a string of comma-separated numbers (in no particular order and they are all 1 or greater)I need to do a query where I select stuff from this table where a certain number exists in that comma separated string.For example the string might be '10,9,1,2,4'Then if the number I am looking for is '1', that row would be returned.To further complicate things, I would like to be able to query it for multiple numbers at once (and it's only returned if ALL of them are there). I'm trying to concatenate two fields in Oracle SQL Developer.
