create a new field push it through data cleanese say remove punctuation, numbers etc (everything but letters); then use this formula

 

left([field],1) =left([new field]) and  right([field],1) =right([new field]) , if true then starts and end with an alphabet character but @Sarath27 that would be not using regex

@Sarath27 when you say 'find a string', are you looking to Filter? If so, the following expression will isolate only records that start and end with numbers (just replace [Input] with your own field):

 

 

IsInteger(Left([Input], 1))
&&
IsInteger(Right([Input], 1))

Hi @Sarath27,

 

@binu_acs is close but there's just an issue with the brackets used and the quotation marks:

 

Regex_MATCH([Field],'^\d.*\d$')

 

Kind regards,

Jonathan

@Jonathan-Sherman his use of double quotes is correct. You can use Single or Double quotes as long as both are the same.

@cjaneczko they are but it's the use of two right unicode double quotation marks that's the issue, not the fact that it's a double quote.

 

Kind regards,

@Sarath27 I updated my original post as the answer was submitted from my phone which doesn't support the proper double quotes
