    <p>I have a dictionary that I want to add all the values to an sqlite database. All the keys in the dictionary exist in the database, and all the keys are of type string. Yet, I am having trouble with getting the values into the database. The following code is ugly, insecure, and errors whenever it comes across a string with a " in it, but it sort of works. </p> <pre><code>Query="INSERT INTO packages VALUES(" for tag in Tags: Query=Query + '"' + Package[tag] + '", ' Query=Query[:-2]+")" cursor.execute(Query) </code></pre> <p>How can I elegantly fix this so that it is secure and accepts inputs with " in the string? I've come across a handful of other methods. For example:</p> <pre><code>fields = Package.keys() values = Package.values() query = "INSERT INTO packages (%s) VALUES (%%s);" % (",".join(fields)) cursor.execute(query, values) </code></pre> <p>but it throws a type error. </p> <pre><code>TypeError: function takes at most 2 arguments (38 given) </code></pre> <p>The most elegant solution I have come across so far appears to be</p> <pre><code>sql_insert = ('INSERT INTO packages (%s) VALUES (%s)' % (','.join('%s' % name for name in Package), ','.join('%%(%s)s' % name for name in Package))) cursor.execute(sql_insert, Package) </code></pre> <p>but it throws an operational error, saying</p> <pre><code>sqlite3.OperationalError: near "%": syntax error </code></pre> <p>Once again, my question is how can I elegantly safely add the values from a dictionary to a database? </p> <p>P.S. It may also be worthy to note that I am using Python 2.5.1. </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.
