SQL - 테이블로 데이터 채우기가 있습니다.

Question

SQL 문을 사용하여 레코드 수를 가진 임시 테이블을 만듭니다.이 테이블은 4 개의 필드, 설명 자 및 3 개의 정수를 삽입합니다. 마지막 필드 CountBYODEntityStagingTable은 실제로 내가 연결된 sp_addlinkedserver이라는 다른 데이터베이스입니다. 때로는 테이블이 게시되지 않은 경우 존재하지 않습니다.

아래 계산서에 어떤 논리를 추가하여 계산을 시도하기 전에 테이블이 존재 하는지를 확인할 수 있으므로 오류가 발생하지 않습니다.

INSERT INTO #TempTable (
    EntityName, 
    CountMainTable, 
    CountEntityView, 
    CountEntityStagingTable, 
    CountBYODEntityStagingTable 
) VALUES 
('CustTransEntity', (SELECT count(*) FROM CustTrans), (SELECT count(*) FROM CustTransEntity), (SELECT count(*) FROM CustTransEntityStaging), (SELECT count(*) FROM DEVBYOD.dbo.CustTransEntityStaging)), 
('VendTransEntity', (SELECT count(*) FROM VendTrans), (SELECT count(*) FROM VendTransEntity), (SELECT count(*) FROM VendTransEntityStaging), (SELECT count(*) FROM DEVBYOD.dbo.VendTransEntityStaging)), 
('TaxTransEntity', (SELECT count(*) FROM TaxTrans), (SELECT count(*) FROM TaxTransEntity), (SELECT count(*) FROM TaxTransEntityStaging), (SELECT count(*) FROM DEVBYOD.dbo.TaxTransEntityStaging))

Answer 1

당신이 뭔가를 할 수 있도록 할 수 있습니다. LinkedSserver가 어떤 종류의 데이터베이스인지는 알 수 없지만 SQL 데이터베이스에서는 작동합니다.

SQL 변수에서 YOURDATABASENAME을 변경해야합니다.

DECLARE @CustTransNo int = (select count(*) from CUSTRANS) 
DECLARE @VendTransNo int =(select count(*) from VendTrans) 
DECLARE @TaxTransNo int =(select count(*) from TaxTrans) 

DECLARE @CustTransEntity int = (select count(*) from CustTransEntity) 
DECLARE @VendTransEntity int =(select count(*) from VendTransEntity) 
DECLARE @TaxTransEntity int =(select count(*) from TaxTransEntity) 


DECLARE @CustTransEntityStaging int = (select count(*) from CustTransEntityStaging) 
DECLARE @VendTransEntityStaging int =(select count(*) from VendTransEntityStaging) 
DECLARE @TaxTransEntityStaging int =(select count(*) from TaxTransEntityStaging)

Answer 2

나는 간단한 방법은 (작성된 테이블)에 존재하는 모든 테이블에 대한 마스터 테이블을 유지하는 것입니다 생각합니다. 그리고 삽입하는 동안 그냥 마스터 테이블을 확인하십시오. 이 경우에는 오류가 발생하지 않을 것입니다.

INSERT INTO #TempTable (EntityName, CountMainTable, CountEntityView, CountEntityStagingTable, CountBYODEntityStagingTable) VALUES 
('CustTransEntity', (SELECT count(*) FROM CustTrans), (SELECT count(*) FROM CustTransEntity), (SELECT count(*) FROM CustTransEntityStaging), (SELECT CASE WHEN CustTransEntityStaging = (SELECT * from TableMaster) THEN (select CAST(COUNT(*) as varchar) from DEVBYOD.dbo.CustTransEntityStaging) ELSE 'No such Table' END)) 

Answer 3

이것은 간단합니다!
