I used Leonard Challis’s technique with a few changes: CREATE TEMPORARY TABLE tmptable_1 SELECT * FROM table WHERE primarykey = 1; UPDATE tmptable_1 SET primarykey = NULL; INSERT INTO table SELECT * FROM tmptable_1; DROP TEMPORARY TABLE IF EXISTS tmptable_1; As a temp table, there should never be more than one record, so you don’t … Read more
I think you have 2 ways – simplier and slowier solution or faster complicated. use Rolling.apply and test pattern replace 0s to NaNs by mask use bfill with limit (same as fillna with method=’bfill’) for repeat 1 then fillna NaNs to 0 last cast to bool by astype pat = np.asarray([1, 2, 2, 0]) N … Read more
Tables are iffy (at least, in IE) when it comes to fixing heights and not wrapping text. I think you’ll find that the only solution is to put the text inside a div element, like so: td.container > div { width: 100%; height: 100%; overflow:hidden; } td.container { height: 20px; } <table> <tr> <td class=”container”> … Read more
You can just check the return value directly. $stmt = $conn->prepare(‘SELECT * FROM table WHERE ID=?’); $stmt->bindParam(1, $_GET[‘id’], PDO::PARAM_INT); $stmt->execute(); $row = $stmt->fetch(PDO::FETCH_ASSOC); if( ! $row) { echo ‘nothing found’; } /* $rows = $stmt->fetchAll(PDO::FETCH_ASSOC); // Same here if( ! $rows) { echo ‘nothing found’; } */ If you are asking about checking without fetching … Read more
The row obtained from columnAtPoint() is in view coordinates, while removeRow() assumes model coordinates. Quoting from the relevant tutorial section: This distinction does not matter unless your viewed data has been rearranged by sorting, filtering, or user manipulation of columns. If so, you will need to use convertRowIndexToModel(), described near the end of Sorting and … Read more
The key idea is you form a set of the rows you want to remove, and keep the complement of that set. In R, the complement of a set is given by the ‘-‘ operator. So, assuming the data.frame is called myData: myData[-c(2, 4, 6), ] # notice the – Of course, don’t forget to … Read more

You can call apply pass axis=1 to apply row-wise, then convert the dtype to str and join: In [153]: df[‘ColumnA’] = df[df.columns[1:]].apply( lambda x: ‘,’.join(x.dropna().astype(str)), axis=1 ) df Out[153]: Column1 Column2 Column3 Column4 Column5 ColumnA 0 a 1 2 3 4 1,2,3,4 1 a 3 4 5 NaN 3,4,5 2 b 6 7 8 NaN … Read more
Use a selector that will select all the rows and take the length. var rowCount = $(‘#myTable tr’).length; Note: this approach also counts all trs of every nested table!
