Description
Some Oracle variable types do not have a direct translation in Snowflake. Currently, transformation for cursor, collection, record, and user-defined type variables; as well as placeholders, objects, and output parameters are not supported by Snow Scripting.
Changing these variables to Snowflake could help as a workaround in some scenarios.
Example Code
Input Code:
IN -> Oracle_01.sql
CREATE OR REPLACE PROCEDURE pinvalidassign(out_parameter IN OUT NUMBER)
AS
record_variable employees%ROWTYPE;
TYPE cursor_type IS REF CURSOR;
cursor1 cursor_type;
cursor2 SYS_REFCURSOR;
TYPE collection_type IS TABLE OF NUMBER INDEX BY VARCHAR(64);
collection_variable collection_type;
BEGIN
--Record Example
record_variable.last_name := 'Ortiz';
--Cursor Example
cursor1 := cursor2;
--Collection
collection_variable('Test') := 5;
--Out Parameter
out_parameter := 123;
END;
Output Code:
OUT -> Oracle_01.sql
CREATE OR REPLACE PROCEDURE pinvalidassign (out_parameter NUMBER(38, 18))
RETURNS VARIANT

Recommendations
Change the variable data type or try to simulate the behavior using Snowflake .
