This syntax is partially supported in Snowflake.
Sybase allow row limitation in a query by using TOP clause with an optional START AT that Snowflake not supports but can transformed as down below to achieve the same functionality.
In Sybase a Table can be defined by selecting multiple rows and defining a name to stored the date retrieved. Snowflake does not support this behavior but can emulated by doing a CREATE TABLE AS.
Snowflake does not contain indexes for query optimization.
In Sybase, during execution, the DML statement specified in the dml-derived table is executed first, and the rows affected by that DML materialize into a temporary table whose columns are described by the REFERENCING clause. The temporary table represents the result set of dml-derived-table. Snowflake does not support this behavior.
Snowflake does not support KEY join but when the ON CLAUSE is defined in the query the KEY keyword and removed otherwise an EWI is inserted.
Snowflake transforms the clause the CROSS APPLY into LEFT OUTER JOIN and OUTER APPLY to INNER JOIN.

Snowflake allows calling a stored procedure(when the procedure meets certain ) or a table value function in a FROM clause, but RESULTSETS and windowing cannot be used as parameters.
Snowflake does not support functionality.
In Sybase the clause following a table name to filter the table and return only those rows matching the full text query specified with contains-query. Every matching row of the table is returned together with a score column that can be referred to using score-correlation-name. Snowflake does not support this behavior.
