NodeJS and MariaDB, Placeholder inside Queries











up vote

favorite












I'm pretty new to Mariadb.
I want to execute a Insert statement with placeholders for the values but also for the columns. I've tried the ? and the ?? for the columns but still getting the Error, that sql syntax is wrong:



let query = "INSERT INTO Users(??, ??, ??, ??, ??) VALUES(?,?,?,?,?);"
let data = [ 'email','forename', 'location','longitude','latitude',
,'test','test','test',1,1 ]
conn.query(query, data)


What is wrong here?



Thanks

          the only not supported things compare to mysql connector is those "Escaping query identifiers".



          The reasons are :




          • First, i don't see the use case for that. Is there any !?

          • I would prefer to have standard MariaDB SQL syntax with only ? as placeholder.


          The reason to have only ? as a placeholder is that when connector will be using binary protocol (not yet implemented) connector won't have to parse the SQL command, then perform better.



          But you can rewrite the command as :



          let query = "INSERT INTO Users(`email`,`forename, `location`,`longitude`,`latitude`) VALUES(?,?,?,?,?);"
          let data = ['test','test','test',1,1]
          conn.query(query, data)


          If you see some use case for that. feel free to create an issue on github

          • I have a lot of different tables with optional fields. My idea was that I don't have build a query for every possible option. To keep the prevention of SQL Injection, i wanted to count how many of the columns wants the user to update and then first build the query with placeholders
