Question

I need a regular expression to find the single quotes in (Anand’s & boy’s) of the below scenario,

'This has to be Anand's first task', 'A boy's friend works in France'

Consider I have many fields to be inserted in to DB like what I have shown in the example above.

I have error with the queries which has a single quote in its text. I need to find them and replace with ” two single quotes for this to solve.

Can you help me in writing the regex for this purpose? As I do not have much insight on regEx.

You should rather be working on how to make sure that you don’t get these obviously incorrect quotes in your input in the first place. But if you can’t, you have a fighting chance by finding quotes that are not followed by a comma (or end of string) and are not preceded by a comma (or start of string):

String resultString = subjectString.replaceAll("(?<!^|, ?)'(?!,|$)", "''");
