Can not store the correct XML Schema facet value in MySQL table

Hi experts

I have a problem with storing facet value in MySQL table. Here is the code:

public void insertFacet(int vid, int pathid, int pPathid, String fName, String fValue) throws SQLException {
        Connection con = startDBConnection(server_name,databse_name,username,password);
        try {           
            Statement statement = con.createStatement();
            String query = "INSERT INTO facet VALUES("
                    + vid + ", " + pathid + ", " + pPathid + ", '" 
                    + fName + "', '" + fValue + "') ";
            statement.execute(query);
            statement.close();
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

Open in new window


I use java language. When I parse XML Schema, it stores the value of the 'pattern' facet but ignore the backslash symbol \
For example the facet
<xs:pattern value="\d{1,2}"/>

Open in new window

is stored like this:
d{1,2}

Open in new window


Any suggestion why this is happening and how to solve it?

Use a PreparedStatement. It will handle escaping correctly for you

Could you explain more please.
Do you mean the replaceAll() function that is used for java string?

Thanks CEHJ

I make a simple alteration and the problem is solved.

I add the replace function like this:
fValue = fValue.replace("\\", "\\\\");

You don't need to escape it yourself - the PreparedStatement will do it for you. If your xml changes to include further chars that need escaping, your home-made code will break
