SQL Server存储过程和用户​​查询之间的区别

Question

We have a stored procedure that pulls information from a few different tables to display some information. This works fine.

We now want to "borrow" some of the code and I'm trying to do some dev work. When I copy the contents of the stored procedure out into a query window and run it (minus the stored procedure related stuff), it completes successfully but no results are returned - in fact #test2 is not populated. Running the same via the stored procedure returns results normally.

Code is below from the query - stored procedure is the same just with ALTER PROCEDURE and I have changed all the table names etc...

    SET ANSI_NULLS ON
    GO

    SET QUOTED_IDENTIFIER ON
    GO

    DECLARE @reportstart smalldatetime, @reportend smalldatetime  

    SET @reportend = 2016-01-01
    SET @reportstart = 2016-02-01

    SET NOCOUNT ON;

    SELECT 
        OPA10.[PATIENT PATHWAY IDENTIFIER], OPA10.RTTPeriod

Answer 1

You need to quote date with ' :

DECLARE @reportstart smalldatetime, @reportend smalldatetime;                 

SET @reportend = '2016-01-01';
SET @reportstart = '2016-02-01';

Otherwise you will get implicit conversion from INT to DATE which is year 1905.

It works similiar to this:

SET @reportend = 2016-01-01;
--SET @reportend = 2014   -- int
--SET @reportend = DATEADD(d, 2014,'1900-01-01')
--SET @reportend = '1905-07-08 00:00:00'

I highly doubt that you have data from 1905 😎
