How to remove certain strings from rows in MySQL -


i attempting clean in messy table consisting of words unnecessary. example below shows typical content:

row1        | ------------- text <12>   | more [dada] | (123) foo   | la {55w} da |

basically define unnecessary content words starting , ending particular symbol: <...>, [...], {...} , (...). use replace function, since data inside of symbols arbitrary not quite possible.

is possible use kind of regex in replace function?

update

please take notice content wrapped inside symbols can letters , numbers, unpredictable.

ok see !
use replace this - see example(will clean inside '()')
