Default parameters may need to be reordered. Snowflake only supports default parameters at the end of the parameter declarations.

Example Code

CREATE PROCEDURE MySampleProc
    @Param1 NVARCHAR(50) = NULL,
    @Param2 NVARCHAR(10),
    @Param3 NVARCHAR(10) = NULL,
    @Param4 NVARCHAR(10)
AS   
    SELECT 1;

Output Code:

OUT -> SqlServer_01.sql

CREATE OR REPLACE PROCEDURE MySampleProc
