How to remove [] from a query result


ricmcdonald

Recommended Posts

I have a query that returns a result enclosed in [ ] and I want to remove these brackets 

 

I can successfully get rid of the right or left bracket but not both using a trim

 

TRIM(Trailing ']' FROM g.field_value) AS Genre 

 

but if i add a TRIM(leading '['     i get an error 

 

if the characters were both the same then TRIM(both ']' will work but they are not

 

Do you have a solution

I agree - it could be an indication that something is wrong - but data can be sourced from all sorts of places, sometimes it is a case of just having to deal with it.  It's especially the case when the data is from a third party and there may be nothing you can do with the source data, you massage it to fit into what you need.  

Working with data loads can provide a great insight into what people try and do and your left with the impression that relying on people to do anything correctly and consistently is like trying to juggle water.

If the data comes from a third party (which is pure speculation), then you sanitize it before putting it into the database. Even the weakest programming language is far better at string operations than any MySQL hack.

 

In any case, I'd be careful with literal answers. Users often fail to show their actual problem and only post random ideas they've come up with. Implementing those ideas may not solve the problem at all.
