# AWS Clean Rooms Spark SQL conditions
<a name="sql-conditions-topic-spark"></a>

 Conditions are statements of one or more expressions and logical operators that evaluate to true, false, or unknown. Conditions are also sometimes referred to as predicates.

**Syntax**

```
comparison_condition
| logical_condition
| range_condition
| pattern_matching_condition
| null_condition
| EXISTS_condition
| IN_condition
```

**Note**  
All string comparisons and LIKE pattern matches are case-sensitive. For example, 'A' and 'a' do not match. However, you can do a case-insensitive pattern match by using the ILIKE predicate.

The following SQL conditions are supported in AWS Clean Rooms Spark SQL.
