java - Why am i getting an illegal character error on an sql query? -


the error states index of illegal character 6 6th character space after select

    static final string jdbc_driver = "com.mysql.jdbc.driver"; static final string db_url = "jdbc:mysql://sql3.freemysqlhosting.net:3306/";  static final string user = "****"; static final string pass = "****";  public jsonarray getlocation(arraylist postparameters) {     connection conn = null;     httpentity httpentity = null;     try{          class.forname(jdbc_driver);          system.out.println("connecting ");         conn = drivermanager.getconnection(db_url, user, pass);         system.out.println("connection successful.");          string sql = "select * locations loctag '%"+postparameters+"%'";          defaulthttpclient httpclient = new defaulthttpclient();          httppost httppost = new httppost(sql);         httppost.setentity(new urlencodedformentity(postparameters,"utf-8"));         httpresponse httpresponse = httpclient.execute(httppost);         httpentity = httpresponse.getentity();

i getting

java.lang.illegalargumentexception: illegal character in path @ index 6: select * locations loctag = '%[loctag=fast]%'

i have tried encoding no luck.

you trying execute sql query http request. makes no sense @ all. httppost constructor expects uri, select statement not uri.

you either need use jdbc execute query, or need or post uri. can't tell code trying though.
