徵狀

假設您有包含 DATE 資料類型資料行的資料表,且您已在 Microsoft SQL Server 2014 的此資料表中實現聚集欄商店索引(CCSI)。 當您嘗試使用 DATE 資料類型做為限定詞來查詢資料表時,可能會傳回不正確的資料。例如:create table tab2(c1 int, c2 date, c3 varchar(10)) CREATE CLUSTERED COLUMNSTORE INDEX [CCI_tab2] ON [tab2] WITH (DROP_EXISTING = OFF)GO select *FROM tab2 S -- Table with clustered columnstore indexWHERE S.c2 = @date -- variable of Date datatype

解決方案

Service pack 資訊

若要解決此問題,請取得 SQL Server 2014 的 Service Pack 1。

如需 SQL Server 2014 Service Pack 1 (SP1)的詳細資訊,請參閱 在 Sql server 2014 Service pack 1 中修正的錯誤

使用下列程式碼再現這個問題:create table tab1(c1 int, c2 date) insert into tab1values (1 , '2000-01-01') CREATE NONCLUSTERED INDEX [idxtab1c2] ON tab1( c2 ASC)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, ONLINE = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) create table tab2(c1 int, c2 date, c3 varchar(10)) insert into tab2values (1, '2000-01-01', 'test') CREATE CLUSTERED COLUMNSTORE INDEX [CCI_tab2] ON [tab2] WITH (DROP_EXISTING = OFF)GO create table t([runId] int not null, [scalingFactor] float not null) -- REPRO QUERY. Below batch is expected to return a row but we don’t get ittruncate table tDECLARE @date DATE, @numDates INT INSERT INTO t VALUES(1, 1)DECLARE @date DATE, @numDates INTSELECT @date = max(R.c2) , @numDates = COUNT(distinct R.c2)FROM tab1 R INNER JOIN t D ON R.c1 = D.runId select *FROM tab2 S -- CCIWHERE S.c2 = @date
