How to Insert or Update table On base of Name value in Sqlite android -

public long createcountry(string code, string name, string continent,      string region) {       contentvalues initialvalues = new contentvalues();      initialvalues.put(key_product_type, code);      initialvalues.put(key_product_name, name);      initialvalues.put(key_product_quantity, continent);      initialvalues.put(key_prodcut_cost, region);       return mdb.insertwithonconflict(sqlite_table, null, initialvalues, sqlitedatabase.conflict_replace);       } 

this insert or update function taking new row if name x alredy present in table row want should update suppose have 3 entry name column value has x,y,z suppose want call again function name x rest of value should update not should create column please me doing wrong .

there no update-or-insert function. have manually:

public void createcountry(string code, string name, string continent, string region) {     contentvalues values = new contentvalues();     values.put(key_product_type, code);     values.put(key_product_quantity, continent);     values.put(key_prodcut_cost, region);     int updated = mdb.update(sqlite_table, values,                     key_product_name + " = ?",                     new string[]{ name });     if (updated == 0) {         values.put(key_product_name, name);         mdb.insert(sqlite_table, null, values);     } }
