Hi everyone,
I have a SQL table in which there is a name column. I found these 3 names which contains "single quote" but all 3 are different types of "single quotes".
I am using replace function to remove this quoute but its only removing it from the last name.
How can I remove it from all 3 names?

They are different characters and therefore multiple nested REPLACE commands would be required.
```
DECLARE @x VARCHAR(50) = CONCAT ('Some''', CHAR (96), CHAR (145), CHAR (146));

SELECT @x
      ,REPLACE (REPLACE (REPLACE (REPLACE (@x, '''', ''), CHAR (96), ''), CHAR (145), ''), CHAR (146), '');
```

but this leads to the question - why do you need to remove them? they are valid characters and if the output is being displayed anywhere for users removing those is a big issue as you are CHANGING what the name of the individuals is.

what should be done if nothing else is replacing the "smart quote", normally used by Word and similar word processing applications with the correct apostrophe.

Requirement of client. They asked to deliver it in this format. It is their problem if name of individual is changed. We just have to apply these changes.
