SSC-FDM-OR0033

DBMS_RANDOM.VALUE Built-In Package precision is lower in Snowflake

Description

This message is shown when SnowConvert migrates a DBMS_RANDOM.VALUE Oracle built-in package function. This warning indicates that the UDF added to emulate the functionality has lower precision than the original function.

Example code

Input Code:

IN -> Oracle_01.sql

CREATE OR REPLACE PROCEDURE built_in_package_proc
IS
var1 NUMBER;
BEGIN
    SELECT DBMS_RANDOM.VALUE() INTO var1 FROM DUAL;

    SELECT DBMS_RANDOM.VALUE(2,10) INTO var1 FROM DUAL; 
END;

Output Code:

OUT -> Oracle_01.sql

CREATE OR REPLACE PROCEDURE built_in_package_proc ()
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},{"attributes":{"component":"oracle"}}'
EXECUTE AS CALLER
AS
$$
    DECLARE
        var1 NUMBER(38, 18);
    BEGIN
        SELECT
            --** SSC-FDM-OR0033 - DBMS_RANDOM.VALUE DIGITS OF PRECISION ARE LOWER IN SNOWFLAKE **
            DBMS_RANDOM.VALUE_UDF() INTO
            :var1
        FROM DUAL;

        SELECT
            --** SSC-FDM-OR0033 - DBMS_RANDOM.VALUE DIGITS OF PRECISION ARE LOWER IN SNOWFLAKE **
            DBMS_RANDOM.VALUE_UDF(2,10) INTO
            :var1
        FROM DUAL;
    END;
