У меня есть запрос SQL Server:
CREATE PROCEDURE [dbo].[usp_GetBuyHoldSellValuationAdjusted_PE]
(@userName VARCHAR(255) = NULL,
@companyCode VARCHAR(255) = NULL,
@portfolioCode VARCHAR(255) = NULL,
@regionCode VARCHAR(255) = NULL,
@sectorCode VARCHAR(255) = NULL,
@countryCode VARCHAR(255) = NULL,
@recommend VARCHAR(255) = NULL,
@universe VARCHAR(20) = NULL,
@includeWatches BIT = NULL,
@economicClassificationCode VARCHAR(20) = NULL,
@InvestmentTypeCode VARCHAR(20) = NULL)
AS
BEGIN
Как преобразовать эту часть в версию Oracle PL / SQL?
