    <p>I can recommend the following options:</p> <p>1) I would embed query parameters directly in the query, I would pass then separately as a tuple/dict to the cursor.execute (see your db api for exact formatting) method: </p> <pre><code>app_phone = 5555555555 query_string="""SELECT biz_name, biz_addr, biz_owner FROM business_t WHERE regexp_replace(biz_phone_1, E'\\\\D|^1', '', 'g') = '%(phone)s' OR regexp_replace(biz_phone_2, E'\\\\D|^1', '', 'g') = '%(phone)s' OR regexp_replace(biz_cell_1, E'\\\\D|^1', '', 'g') = '%(phone)s' OR regexp_replace(biz_cell_2, E'\\\\D|^1', '', 'g') = '%(phone)s'; """ result = run_query(query_string, {'phone': app_phone}) </code></pre> <p>This solution will save you from (most) sql injection attacks</p> <p>2) To build the query you can consider using sql query building library (<a href="https://pypi.python.org/pypi/python-sql/0.2" rel="nofollow">https://pypi.python.org/pypi/python-sql/0.2</a>). That will allow you to build SQL queries in terms of expressions, not using string editing. Not sure if this query builder will support usage of regexp in where though</p> <p>3) You can try to use loop, but the question if it's become more readable will be subjective, imho:</p> <pre><code>app_phone = 5555555555 cmp_phones = "regexp_replace(%s, E'\\\\D|^1', '', 'g') = '%%(phone)s'" db_phone_columns = (biz_phone_1, biz_phone_2, biz_cell_1, biz_cell_2) where_condition = 'OR'.join(cmp_phones % phone for phone in db_phone_columns) result = run_query(query_string, {'phone': app_phone} query_string="""SELECT biz_name, biz_addr, biz_owner FROM business_t WHERE %(where_condition)s;""" % {'where_condition': where_condition} result = run_query(query_string, {'phone': app_phone}) </code></pre> <p>I personally find solution 1) most readable</p> <p>4) Use stored procedure with phone as a parameter</p> <p>5) Formatting of the query inside the query string that I personally prefer is demonstrated in the examples</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
