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 semi-structured data types 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

--** SSC-FDM-0007 - MISSING DEPENDENT OBJECT "employees" **
CREATE OR REPLACE PROCEDURE pinvalidassign (out_parameter OUT NUMBER(38, 18))

Recommendations

• Change the variable data type or try to simulate the behavior using Snowflake semi-structured data types.
