SQL Server 2008 Express : find similar records in a table -

-

here first question sql server 2008 express database, containing articles, quantities, prices , on. unfortunately when loaded data first time loaded articles making following mistake:

i created 2 records (almost) every article similar different character.

here's example:

  • tuto510088.9x3
  • tuto510088,9x3

the different character , , .. there way select these articles delete ones comma , leaving others?

please note position of different character not fixed, on 3rd right, or in middle

you can using self join:

delete t2 tablename t1 join      tablename t2 on replace(t1.article,'.','')=replace(t2.article,',','') t2.article '%,%'

demo in sql fiddle

you can check records going deleted replacing delete t2 select t2.*

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .
