First of all - all credits goes to Laurenz Albe answer here
I hava a JSONB colum where I need to perform a search on the values (exactly as explained in the linked question). I think to get advantage from the answer there and the trigram index. However in the answer the regex which is searched is hardcoded directly WHERE visitors::text *~ '\mJohn Doe\M';
My value comes from the front end where the user enters a search string which is named in the postgres function as search_term
.
If I was to use the answer directly I would have to execute WHERE visitors::text search_term
which obviously won't work.
My question is how to continue the query so that I can modify the search_term
variable and get the same effet as the *~ '\mJohn Doe\M'
in the original post?
