Hello How can I use this select and skip value with simple quotation mark?

.
.
.st.executeQuery("select * from tabela_A where id = uc");

        rs = st.getResultSet();


        while (rs.next()) {

                texto = rs.getString("rua")
           }...

...the problem is that when the street is for example Passo'Dareia, I want to eliminate this simple quote, because otherwise I will have an error in the sequence of the system...

ps. the select is being done in MYSQL, and the return(rs.getString) used in a JSP page.

  • What error for example? You want to delete in the return or it can be later, within the same text variable?

You can treat the return right away in the result.

texto = rs.getString("rua");
if (null != texto) {
  texto = texto.replaceAll("\'","");
}

  • So that the counter?

  • Backslash serves to escape the character and be accepted as it is being used. It would not work without it.

  • replaceAll takes a regular expression (Regex), so you need to escape the single quote.

  • @ricktg But it is not better to use texto.replace("'", "")? What would be the justification for using regular expression?

  • It is neither better nor worse because the two methods use Pattern and Matcher to perform the search. In my opinion the regex is more assertive in the char search.

  • Thank you very much! That’s right....
