Moving table from one database to another with primary key and other keys - sql

Question

I want to move all the table from one database to another with primary key and all other keys
using SQL queries. I am using SQL Server 2005 and I got a SQL queries to move the table but the keys are not moved.
And my queries is as follows
set #cSQL='Select Name from SRCDB.sys.tables where Type=''U'''
Insert into #TempTable
exec (#cSQL)
while((select count(tName) from #t1Table)>0)
begin
select top 1 #cName=tName from #t1Table
set #cSQL='Select * into NEWDB.dbo.'+#cName+' from SRCDB.dbo.'+#cName +' where 1=2'
exec(#cSQL)
delete from #t1Table where tName=#cName
end
where SRCDB is the name of source database and NEWDB is the name of destination database
How can I achieve this..?
Can anyone help me in this...
Thank you...

The following T-SQL statement move all the table, primary key and foreign key from one database to another. Notice that the method SELECT * INTO FROM ... WHERE 1 = 2 does not create COMPUTED columns and user-data types. Suppose also that all primary keys are clustered
--ROLLBACK
SET XACT_ABORT ON
BEGIN TRAN
DECLARE #dsql nvarchar(max) = N''
SELECT #dsql += ' SELECT * INTO NEWDB.dbo.' + name + ' FROM SRCDB.dbo. ' + name + ' WHERE 1 = 2'
FROM sys.tables
--PRINT #dsql
EXEC sp_executesql #dsql
SET #dsql = N''
;WITH cte AS
(SELECT 1 AS orderForExec, table_name, column_name, constraint_name, ordinal_position,
'PRIMARY KEY' AS defConst, NULL AS refTable, NULL AS refCol
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE OBJECTPROPERTY(OBJECT_ID(constraint_name), 'IsPrimaryKey') = 1
UNION ALL
SELECT 2, t3.table_name, t3.column_name, t1.constraint_name, t3.ordinal_position,
'FOREIGN KEY', t2.table_name, t2.column_name
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS as t1
JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE t2 ON t1 .UNIQUE_CONSTRAINT_NAME = t2.CONSTRAINT_NAME
JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE t3 ON t1.CONSTRAINT_NAME = t3.CONSTRAINT_NAME
AND t3.ordinal_position = t2.ordinal_position
)
SELECT #dsql += ' ALTER TABLE NEWDB.dbo.' + c1.table_name +
' ADD CONSTRAINT ' + c1.constraint_name + ' ' + c1.defConst + ' (' +
STUFF((SELECT ',' + c2.column_name
FROM cte c2
WHERE c2.constraint_name = c1.constraint_name
ORDER BY c2.ordinal_position ASC
FOR XML PATH(''), TYPE
).value('.', 'nvarchar(max)'), 1, 1, '') + ')' +
CASE WHEN defConst = 'FOREIGN KEY' THEN ' REFERENCES ' + c1.refTable + ' (' +
STUFF((SELECT ',' + c2.refCol
FROM cte c2
WHERE c2.constraint_name = c1.constraint_name
ORDER BY c2.ordinal_position ASC
FOR XML PATH(''), TYPE
).value('.', 'nvarchar(max)'), 1, 1, '') + ')' ELSE '' END
FROM (SELECT DISTINCT orderForExec, table_name, defConst, constraint_name, refTable FROM cte) AS c1
ORDER BY orderForExec
--PRINT #dsql
EXEC sp_executesql #dsql
COMMIT TRAN

You can generate customized script of Source Database and run the script for Destination Database.
Here is the link and slightly better [one][2]
Get the complete table and then perform the delete queries on Destination database as per requirement
If you want to do with Query. I guess this link would be helpful

DECLARE #strSQL NVARCHAR(MAX)
DECLARE #Name VARCHAR(50)
SELECT Name into #TempTable FROM SRCDB.sys.tables WHERE Type='U'
WHILE((SELECT COUNT(Name) FROM #TempTable) > 0)
BEGIN
SELECT TOP 1 #Name = Name FROM #TempTable
SET #strSQL = 'SELECT * INTO NEWDB.dbo.[' + #Name + '] FROM SRCDB.dbo.[' + #Name + ']'
EXEC(#strSQL)
DELETE FROM #TempTable WHERE Name = #Name
END
DROP TABLE #TempTable
If you have destination table already created then just set identity insert on and change query like below :
SET #strSQL = ' SET IDENTITY_INSERT NEWDB.dbo.[' + #Name + '] ON; ' +
' INSERT INTO NEWDB.dbo.[' + #Name + '] SELECT * FROM SRCDB.dbo.[' + #Name + ']' +
' SET IDENTITY_INSERT NEWDB.dbo.[' + #Name + '] OFF '
UPDATE :
If you don't want records and only want to create table with all key constaints then check this solution :
In SQL Server, how do I generate a CREATE TABLE statement for a given table?

The following script copies many tables from a source DB into another destination DB, taking into account that some of these tables have auto-increment columns:
