Question

I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |

I want to delete the row in the table that has Name myName.

// In onCreate
dbHelper = new DBAdapter(this);
dbHelper.open()

// Function in DBAdapter class
public boolean deleteTitleGivenName(String myName) 
{
    return dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=" + myName, null) > 0;
}

// Function call in java code
dbHelper.deleteTitleGivenName(myName);  // this is where my code fails  

dbHelper.close();           

Just as a note: myName is for sure in the database. Also, I can not use the ROWID since I am getting myName from a ListView.

I just started programming with Android and I have tried for days to solve this problem.
Is my WHERE clause correct (KEY_NAME + “=” + myName)?

Thanks in advance.

Answer 1

Sure, that works, although I would recommend

dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=?", new String[] { myName })

for safety reasons. That way, you can have special characters without breaking your query. Did this not work?
