Question

Whenever the search query contains the ‘ char my android app crashes, because it thinks the ‘ splits the String.
Here’s an example –

Cursor selCur= myDataBase.rawQuery("SELECT * FROM drinks WHERE name like '%"+editTextSearch.getText().toString()+"%'", null);

Whenever editTextSearch.getText().toString() contains a ‘ (for example – “Ben’s”) the app crashes.

I can’t think of anyway around it.
Could really use help.

Thanks!

What you really should do is use the SQLiteDatabase method rawQuery with a String array for selection args:

Cursor selCur= myDataBase.rawQuery("SELECT * FROM drinks WHERE name like ?", new String[] {"%" + editTextSearch.getText().toString() + "%"});

You place a question mark ? in place of the string you wish to have there, and put the actual string in an array, like i have above. You can have multiple ? in your query string, just make sure your array size matches how many ? you have.

Edit: also for using like, you may want to add the % symbol inside the String array like i have just changed. I found that this results in a query that i expect rather than including the % in the query string itself.
