Question

The query(), exec() and rawQuery() methods in the SQLiteDatabase allow binding only Strings to parameters. How do I bind parameters that are not Strings. Specifically, I would like to execute a statement whose where clause contains a parameter that is a (small) blob. How do I bind such values

Thank you.

Answer 1

Convert your type to String before passing it to any of the methods.

To convert an int, use the static method Integer.toString(int). Similarly, to convert a long, use the static method Long.toString(long).

In case of byte[] you can use the String(byte[]) or String(byte[], Charset) constructor. You will need to ensure that you use appropriate and consistent encoding.
