+As in
+[the original post](/blog/add-taxonomy-term-multiple-nodes-using-sql/ 'Quickly adding a taxonomy term to multiple nodes using SQL'),
+I'd generated a list of node ID values, and needed to add structure the SQL
+update statment formatted in a certain way. However, I changed my inital query
+slightly to out put the same nid value twice.
+
+```sql
+SELECT nid, nid FROM node WHERE TYPE = 'blog' ORDER BY nid ASC;
+```
+
+Then, I could select all of the returned rows, copy the values, and paste them
+into Coda:
+
+As before, I needed my SQL update statement to be in the following format:
+
+```sql
+INSERT INTO term_node VALUE (nid, vid, tid), (nid2, vid2, tid);
+```
+
+As I mentioned previously, the nid and vid values are the same for each node,
+and the tid will remain constant. In this case, the tid value that I needed to
+use was '63'.
+
+So, using the 'Find and Replace' function within Coda, combined with
+[regular expressions](http://en.wikipedia.org/wiki/Regular_expression) (regex),
+I can easily format the values as needed. To begin with, I need to ensure that
+the RegEx search option is enabled, and that I'm using the correct escape
+character.
+
+The first thing that I wanted to do was add the seperating comma between the two
+values. To do this, I perform a search for `\s*\t`. This searches for everything
+that is whitespace AND is a tab value. I can then add the comma as the
+replacement for each result.
+
+All 31 lines have been changed.
+
+Next, I can use `\n` to target the lines between the rows. I'll replace it with
+the next comma, the number 63 (the tid value), the closing bracket, another
+comma, re-add the line and add the opening bracket.
+
+The only two lines that aren't changed are the first and last, as they don't
+have any line breaks following them. I can complete these lines manually. Now
+all I need to do is add the beginning of the SQL update statement, then copy and
+paste it into Sequel Pro.
