Annotation Type Query

@Documented
 @Target(value=METHOD)
 @Retention(value=RUNTIME)
public @interface Query

Annotation to support the use of N1QL queries with Couchbase.

Using it without parameter will resolve the query from the method name. Providing a value (an inline N1QL statement) will execute that statement instead.

In this case, one can use a placeholder notation of ?0, ?1 and so on.

Also, SpEL in the form #{spelExpression} is supported, including the following N1QL variables that will be replaced by the underlying CouchbaseTemplate associated information:

• (see StringN1qlBasedQuery.SPEL_SELECT_FROM_CLAUSE)
• (see StringN1qlBasedQuery.SPEL_BUCKET)
• (see StringN1qlBasedQuery.SPEL_ENTITY)
• (see StringN1qlBasedQuery.SPEL_FILTER)
