复制数据库中的所有表并添加新数据，而不影响旧数据SQL

Question

Can anyone help me with a stored procedure that would allow all the tables in a database to be copied and the original tables must be truncated at the end, and when the procedure runs everyday all new data must be copied from the original table to the backup tables without affecting the existing data.

This is what I've done

CREATE PROCEDURE ZS_Backup
AS
BEGIN

SELECT * INTO
 [dbo].[CS_ArrivalsBackUp], 
 [dbo].[CS_awbBackUp],
 [dbo].[CS_awb_arrivalsBackUp],
 [dbo].[CS_awb_dlvBackUp],
 [dbo].[CS_awb_iataBackUp],
 [dbo].[CS_awb_iata_arrivalsBackUp],
 [dbo].[CS_ConsolidationBackUp],
 [dbo].[CS_part_agents],
 [dbo].[CS_part_consignee],
 [dbo].[Evo_Customers],
 [dbo].[Evo_Products],
 [dbo].[int_log_arrivals],
 [dbo].[int_log_deliveries],
 [dbo].[integration_logs],
 [dbo].[period],
 [dbo].[public_holidays],
 [dbo].[rates],
 [dbo].[temp_Rates]

FROM [dbo].[CS_Arrivals],
       [dbo].[CS_awb],
      [dbo].[CS_awb_arrivals],
      [dbo].[CS_awb_dlv],
      [dbo].[CS_awb_iata],
      [dbo].[CS_awb_iata_arrivals],
      [dbo].[CS_Consolidation],
      [dbo].[CS_part_agents],
      [dbo].[CS_part_consignee],
      [dbo].[Evo_Customers],
      [dbo].[Evo_Products],
      [dbo].[int_log_arrivals],
      [dbo].[int_log_deliveries],
      [dbo].[integration_logs],
      [dbo].[period],
      [dbo].[public_holidays],
      [dbo].[rates],
      [dbo].[temp_Rates]

TRUNCATE TABLE [dbo].[CS_Arrivals],
           [dbo].[CS_awb],
           [dbo].[CS_awb_arrivals],
           [dbo].[CS_awb_dlv],
           [dbo].[CS_awb_iata],
           [dbo].[CS_awb_iata_arrivals],
           [dbo].[CS_Consolidation],
           [dbo].[CS_part_agents],
           [dbo].[CS_part_consignee],
           [dbo].[Evo_Customers],
           [dbo].[Evo_Products],
           [dbo].[int_log_arrivals],
           [dbo].[int_log_deliveries],
           [dbo].[integration_logs],
           [dbo].[period],
           [dbo].[public_holidays],
           [dbo].[rates],
           [dbo].[temp_Rates]

           END
           GO

Answer 1

Here you go,

be careful where you run this. For your safety I have commented out the bit that actually does the copy and truncate but instead I have set it so it would show you what would be executed:

DECLARE @table_name nvarchar(1000)
DECLARE @SQL nvarchar(1000)

DECLARE CUR CURSOR 
FOR 
SELECT name 
FROM sys.tables
WHERE type = 'U'
and name IN ('CS_ArrivalsBackUp', 
'CS_awbBackUp',
'CS_awb_arrivalsBackUp',
'CS_awb_dlvBackUp',
'CS_awb_iataBackUp',
'CS_awb_iata_arrivalsBackUp',
'CS_ConsolidationBackUp',
'CS_part_agents',
'CS_part_consignee',
'Evo_Customers',
'Evo_Products',
'int_log_arrivals',
'int_log_deliveries',
'integration_logs',
'period',
'public_holidays',
'rates',
'temp_Rates')
ORDER BY NAME

OPEN CUR

FETCH NEXT FROM CUR
INTO @table_name

WHILE @@FETCH_STATUS = 0  
BEGIN  

PRINT 'SELECT * INTO TMP_' + @table_name + ' FROM ' + @table_name
PRINT 'TRUNCATE TABLE ' + @table_name 

--SET @SQL = 'SELECT * INTO TMP_' + @table_name + ' FROM ' + @table_name
--EXEC (@SQL)

--SET @SQL = 'TRUNCATE TABLE ' + @table_name 
--EXEC (@SQL)

FETCH NEXT FROM CUR INTO @table_name  

END
CLOSE CUR
DEALLOCATE CUR

Answer 2

Okay only a slight change needed. Once your temp tables are created (above in the first run); then for future runs you need:

DECLARE @table_name nvarchar(1000)
DECLARE @SQL nvarchar(1000)

DECLARE CUR CURSOR 
FOR 
SELECT name 
FROM sys.tables
WHERE type = 'U'
and name IN ('CS_ArrivalsBackUp', 
'CS_awbBackUp',
'CS_awb_arrivalsBackUp',
'CS_awb_dlvBackUp',
'CS_awb_iataBackUp',
'CS_awb_iata_arrivalsBackUp',
'CS_ConsolidationBackUp',
'CS_part_agents',
'CS_part_consignee',
'Evo_Customers',
'Evo_Products',
'int_log_arrivals',
'int_log_deliveries',
'integration_logs',
'period',
'public_holidays',
'rates',
'temp_Rates')
ORDER BY NAME

OPEN CUR

FETCH NEXT FROM CUR
INTO @table_name

WHILE @@FETCH_STATUS = 0  
BEGIN  

PRINT 'INSERT INTO TMP_' + @table_name + ' SELECT * FROM_' + @table_name
PRINT 'TRUNCATE TABLE ' + @table_name 

--SET @SQL = 'INSERT INTO TMP_' + @table_name + ' SELECT * FROM_' + @table_name
--EXEC (@SQL)

--SET @SQL = 'TRUNCATE TABLE ' + @table_name 
--EXEC (@SQL)

FETCH NEXT FROM CUR INTO @table_name  

END
CLOSE CUR
DEALLOCATE CUR
