|

<p>I tried to parse SQL that should be valid but it failed, why did that happen?</p>
|
||||
|
||||
<ul>
|
||||
<li>You need to specify the dialect to read the SQL properly, by default it is SQLGlot's dialect which is designed to be a superset of all dialects <code>parse_one(sql, dialect="spark")</code>. If you tried specifying the dialect and it still doesn't work, please file an issue.</li>
|
||||
</ul>
|
||||
|
||||
<p>I tried to output SQL but it's not in the correct dialect!</p>
|
||||
|
||||
<ul>
|
||||
<li>You need to specify the dialect to write the sql properly, by default it is in SQLGlot's dialect <code>parse_one(sql, dialect="spark").sql(dialect="spark")</code>.</li>
|
||||
</ul>
|
||||
|
||||
<p>I tried to parse invalid SQL and it should raise an error but it worked! Why didn't it validate my SQL.</p>
|
||||
|
||||
<ul>
|
||||
<li>SQLGlot is not a validator and designed to be very forgiving, handling things like trailing commas.</li>

<p>This is a typical example of adding a new dialect implementation in SQLGlot: we specify its identifier and string
|
||||
delimiters, as well as what tokens it uses for its types and how they're associated with SQLGlot types. Since
|
||||
the <code>Expression</code> classes are common for each dialect supported in SQLGlot, we may also need to override the generation
|
||||
logic for some expressions; this is usually done by adding new entries to the <code>TRANSFORMS</code> mapping.</p>
|
||||
<p>The above example demonstrates how certain parts of the base <code>Dialect</code> class can be overridden to match a different
|
||||
specification. Even though it is a fairly realistic starting point, we strongly encourage the reader to study existing
|
||||
dialect implementations in order to understand how their various components can be modified, depending on the use-case.</p>
