我在这个问题上遇到了我的 SQL 问题,我已经从 sys.servers 中选择 * 以检查我的服务器是否已列出。
我还完成了从 sys.servers 中选择名称的查询,并列出了我的服务器名称。
这是我的代码
declare @Source_Database_Name AS varchar(255) = 'dbo.Production2'
declare @Destination_Database_Name AS varchar(255) = 'c365online_script1'
declare @Company_Id AS int = 1 --declare a companyid
CREATE TABLE #CompanyID1 (ID bigint)
INSERT INTO #CompanyID1(ID)
VALUES('1')
--FIRST CURSOR LOOP THROUGH THIS TABLE
CREATE TABLE #TableList (
processorder int,
tablename NVARCHAR(100)
)
INSERT INTO #TableList (processorder, tablename )
VALUES
(1, 'tCompany');
DECLARE @firstLoop BIT
--SET @firstLoop = true
DECLARE @Counter INT -- counting variable
----------- Cursor specific code starts here ------------
-- company cursor
declare copyCompanyDataCursor CURSOR fast_forward FOR
SELECT ID from #CompanyID1;
open copyCompanyDataCursor
fetch next from copyCompanyDataCursor into @Company_Id;
WHILE @@FETCH_STATUS = 0
BEGIN
declare @processorder int;
declare @tablename varchar(500);
-- table cursor
declare copyTableDataCursor CURSOR fast_forward FOR
SELECT processorder,tablename from #TableList order by processorder;
open copyTableDataCursor
fetch next from copyTableDataCursor into @processorder, @tablename;
WHILE @@FETCH_STATUS = 0
BEGIN
SET IDENTITY_INSERT [c365online_script1].[dbo].[tCompany] ON
-- Does the table have a companyID column? if statement checking for company id
IF EXISTS(SELECT * FROM Production2.INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME='CompanyID' and TABLE_NAME='tProperty')
BEGIN
declare @debug varchar(max)
EXEC('INSERT INTO ' + @Destination_Database_Name + '.dbo.' + @tablename + ' SELECT * FROM ' + @Source_Database_Name + '.dbo.' + @tablename + ' WHERE ' + @Source_Database_Name + '.dbo.' + @tablename + '.CompanyID = ' + @Company_Id )
END
ELSE
BEGIN
Print 'No'
END
-- if yes then copy data based on companyID in cursor
-- if no check if this is the first time through company loop and copy all data
-- if @firstloop company exists look at information schema
-- insert into c365online_script1.dbo.tCompany(selec
EXEC('INSERT INTO ' + @Destination_Database_Name + '.dbo.' + @tablename + ' SELECT * FROM ' + @Source_Database_Name + '.dbo.' + @tablename )
-- company logic
SET IDENTITY_INSERT [c365online_script1].[dbo].[tCompany] OFF
FETCH NEXT FROM copyTableDataCursor into @processorder,@tablename;
END
close copyTableDataCursor;
Deallocate copyTableDataCursor;
--INSERT INTO c365online_script1.dbo.tCompany
--SELECT *

--WHERE ISNULL(CompanyID, 0) = 0 -- copy all data where id is equal to zero

--SET @firstLoop = false;
FETCH NEXT FROM copyCompanyDataCursor into @Company_Id;
END
CLOSE copyCompanyDataCursor;
DEALLOCATE copyCompanyDataCursor;
