I am trying to use a select statement to query some data from the database's table . when i type =?the query succeed , but when i use LIKE %?% instead i got this error in logcat:
FATAL EXCEPTION: main
Process: com.example.ahmed.bus_time_djerba4, PID: 4178
java.lang.IllegalArgumentException: Cannot bind argument at index 2 because the index is out of range. The statement has 0 parameters.
and this is my methode that call the database:
public String QuerySQL(String DepartStation,String Destination){
String result="";
SQLiteDatabase db=this.getReadableDatabase();
Cursor c=db.rawQuery("select distinct * from "+TABLE_Name+" where "+Col_3+" LIKE '%?%' and "+Col_4+" LIKE '%?%'", new String[]{DepartStation,Destination});
if(c.getCount()==0) {result="Data not found";c.close();}
else {
while (c.moveToNext()) {
//affichage des lignes
int ligne = c.getInt(1);
String Station = c.getString(2);
String Dest = c.getString(3);
String hours = c.getString(4);
result += "\n" + ligne + "|" + Station + "-" + Dest + " " + hours;
}
c.close();
}
return result;
}
what is the problem ? please
answer
The Problem is with the SQL query you have used.
you are giving ? A String which is not acceptable for prepare statements.
you are giving ? A String which is not acceptable for prepare statements.
select distinct * from table_name where X like '%?%';
is not correct because ?
will be a string with double quotation inside a quotation like '%"your_string"%'.
instead write:
select distinct * from table_name where X like ?;
and for
?
use "'%your_string%'
". you can apply this to your array of string too.
