Change a value in a column in sqlite

Question

I need to update a value in a column from a certain table. I tried this :

 public void updateOneColumn(String TABLE_NAME, String Column, String rowId, String Col         


        

Answer 1

Easy solution:

String sql = "UPDATE "+TABLE_NAME +" SET " + ColumnName+ " = '"+newValue+"' WHERE "+Column+ " = "+rowId;

Better solution:

ContentValues cv = new ContentValues();
cv.put(ColumnName, newValue);
db.update(TABLE_NAME, cv, Column + "= ?", new String[] {rowId});
