Can I Export Tables So That Existing Tables In Destination Database Will Be Modified?
Jul 20, 2005
I'm working on an ASP.Net project where I want to test code on a local
machine using a local database as a back-end, and then export it to
the production machine where it uses the hosting provider's SQL Server
database on the back-end. Is there a way to export tables from one
SQL Server database to another in such a way that if a table already
exists in the destination database, it will be updated to reflect the
changes to the local table, without existing data in the destination
table being lost? e.g. suppose I change some tables in my local
database by adding new fields. Can I "export" these changes to the
destination database so that the new fields will be added to the
destination tables (and filled in with default values), without losing
data in the destination tables?
If I run the DTS Import/Export Wizard that comes with SQL Server and
choose "Copy table(s) and view(s) from the source database" and choose
the tables I want to copy, there is apparently no option *not* to copy
the data, and since I don't want to copy the data, that choice doesn't
work. If instead of "Copy table(s) and view(s) from the source
database", I choose "Copy objects and data between SQL Server
databases", then on the following options I can uncheck the "Copy
Data" box to prevent data being copied. But for the "Create
Destination Objects" choices, I have to uncheck "Drop destination
objects first" since I don't want to lose the existing data. But when
I uncheck that and try to do the copy, I get collisions between the
properties of the local table and the existing destination table,
e.g.:
"Table 'wbuser' already has a primary key defined on it."
Is there no way to do what I want using the DTS Import/Export Wizard?
Can it be done some other way?
Hello Friends, I am right now working on a project that has a database with over 100 tables in a database. Because of extreme time constraints the developers didn't build in any relationships or constraints between or in the tables. Now I need to remodel the database such that the database is more structured and normalized. I don't have much knowledge about the database design since it is a 2 year old application and the person who developed the database is now gone. I know remodelling the database would require knowledge of the existing database and business rules. I was wondering if there are any tools that could suggest or discover relationships between tables. For eg. Lets say there are two tables named 'Customer' and 'Order'. I notice that there is a column named 'id' in Customer and a column named 'customer_id' in Order. So I ask the tool to discover a relationship between id and customer_id and it tells me that there is a one-one or one-many or no relationship by comparing values. I heard ERWin would be able to do that but thats expensive. Please do let me know asap.
I would like to replace data of some tables from STG to DEV database daily using SSIS package. Should I use "Transfer SQL Server Objects Task" to do that? Thanks.
A very simple question I have two tables in the database on one server I want to export it to another database on another server How can I do this? I tried DTS but I guess it works from one server to another server on same network When I went to Query Analyzer, I can see scripting options but that only gives me the structure of the table in .sql format Is it possible to get the whole data in .sql format and then run it on another server Please suggest methods Thanks
If we want to get the changes happened in database we will get through sys.objects or sys.tables .but we are only getting it table name . But how to get by table name and what the column added to that table or what column has been modified (datatype or constraint) .
For example if i added employee table column called deptid it should be shown in changes in geiven date
SELECT modify_date ,type_desc ,name FROM sys.objects WHERE is_ms_shipped=0 --AND modify_date>='yyyy/mm/dd' <--optionally put in your date here ORDER BY 1 DESC
How to get column name of a table which is modified...
In the olden days when I used databases that kept each table in a separate file, I used to be able to tell when a specific table was modified by the date stamp on the file.
Is there a method in SQL server to check the "last modifed date" at the table level?
Kazim writes "generally when we find the new software on our customer and when they want to change the software they said "we must see and use the old datas on the new program". but at here the problem is starting for us because of i want to know on any example on the old software which data is stored on which table on sql server or it is possible for this example we can say spy. do you know anything for about this type of the question and how can we check which tables and columnS are affected by the software? thnx."
I am using SQL server 2012. An user tried to export tables from GIS application to the SQL database.
After export, and login to the SQL server, we see all the tables has his name as the schema but not dbo.
He was added as a login and user as in a windows group. Meaning he is a member of the windows group.
I assume when export, the default schema should be dbo. but apparently not. I went to the setting and explicitly make the default schema for the windows group user to dbo. But he tried again, it still use his username as schema prefix to the tables. just wondering why is this?

I've been handed a very old database to knock into shape for an ASP.NET energy monitoring website. The current tables seem to have been created as cross tabs from the meter raw data, and are in the form- CREATE TABLE [dbo].[PW_Table] ( [Date] [int] NULL , [Meter_1] [float] NULL , [Meter_2] [float] NULL , [Meter_3] [float] NULL , [Meter_4] [float] NULL , [Meter_5] [float] NULL , [Meter_6] [float] NULL , [Meter_7] [float] NULL) ON [PRIMARY] I'd like to rearrange them into the format- ReadingID (Identity), ReadingDate (datetime), ReadingValue (float), MeterID (int) I would set up a lookup table for the Meters and join on MeterID. Converting the date value from an int into a DateTime is no problem, but I can't work out how to transpose the meter readings. Can anyone point me towards a way of doing this via SQL, or would it need to be done by hand? Thanks in advance for any help offered.
hello I am working with an existing database and there is no Foreign key between 2 tables how can i create a FK after , when the tables are allready full ?
product :
product_id report_id name
report :
report_id dateR
i want to create a FK on product.report_id, and ON DELETE CASCADE
Player, Position, [From], [To], Fee, Type, ID, League, Window
I want to create a new table, EnglandFinal with all the data from the three tables although I'm guessing it would not be a good idea to copy the primary keys (ID column) as they would clash.
I have played around with CREATE and INSERT into and UNION but I get various errors. I'm sure I've done this before!
Hi guys , assuming right now I already create partition function (PF_Date) and partition scheme (PS_Date). Let say I would like to implement the partition on the existing tables ( eg: transaction table which is in PRIMARY filegroup), how am I switch it from PRIMARY to PS_Date ? Is it I have to re-create the particular table then only able to put in the partition scheme? Hope can get any assistance here. Thanks alot.
I have a requirement like, i need to save all the records from my Flat File on Monthly basis to my database table. In the next month, the flat file may be added with 10-20 records and also some updates happened to my old records. Though the faltfile is same for each month, the changes are occured in some records and also added with few records.
So when i am loading this data in to Database table, i need to just update the changed records and also needs to add the new records. I don't need to touch the remaining records.
How can i do that in SSIS 2005 using different data flow tasks ?
I want to write a SSIS which picks up the source and destination tables at runtime is it possible. As we have a SSIS which is used to pull data from oracle but the source and destination table name changes.
Now, i have a SQL Server database called "EmployeeDB" which has 2 tables "TblEmp1", "TblEmp2". The Table is like this.
TblEmp1 : Columns EmpName EmpDept EmpjoinDate
TblEmp2 : Columns EName EDate Edept
using integration services (SSIS) i need code(vb.net or c#) to Create a dtsx package so that i can push the flat file content to these 2 tables. And the condition is :
After Executing the package Data loaded in TblEmp1 should be like this
Now, i know that we need to do like this in wizard 1) Create a flat file source component. 2) Create flat file connection and set the properties of flat file (delimeters and other things) 3) Create a Multicast Component. 4) Create a Path between Flat file source and Multicast. 5) Create 2 destination component(each for a table). 6) Create path from multicast to 2 destination components 7) Create a OledbConnection and set table names for 2 destination components.. 7) Now,i have to do mapping for destination1.8) Now, i have to do mapping for destination2( this mapping will be different from mapping done for destination1 because iam not inserting the data in the same order in which iam doing for TBLEmp1.
I have done it in wizard.I need to do it through code and i know that its not complicated.Please find the attached file with this mail.i have attached a screen shot of how i have done in wizard.The main problem is Mapping differently for 2 destinations from source.for 1st one we can have a forloop for mapping.but for 2nd one iam confused!!
I need to populate tables in my MS SQL 2000 DB with content from an excel file. I am not sure how this is done or how to format the excel file. If someone could help me with this it would be much appreciated!Thanks!
I have been asked to create PK on many tables using a query on all tables where we do not have clustered indexes. Some of the tables contains PK but non-clustered. If in a table there are no PK, then how to decide on which column PK can be created? can we do it with the query without data loss and without human intervention?
I have a real table with an identity column and a trigger to populate this column.
I need to import / massage data for data loads from a different format, so I have a temp table defined that contains only the columns that are represented in the data file so I can bulk insert.
I then alter this table to add all the other columns so that it reflects all the columns in the real table. I then populate all the values so that this contains the data I need.
I then want to insert into the real table pushing the data from the temp table, however this gives me errors stating that the query returned multiple rows.
I specified all the columns in the insert grouping as well as on the select from the temp table.
ANY thoughts / comments are appreciated. This is beginning to drive me nuts.
I want to combine a series of outputs from tsql queries into a single flat file destination using SSIS.
Does anyone have any inkling into how I would do this.
I know that I can configure a flat file connection manager to accept the output from the first oledb source, but am having difficulty with subsequent queries.
I have a new problem when I import data from an xml source file in two destination tables. The two tables are linked by a foreign key... for example :
table MOTHER (MOTHER_ID, MOTHER_NAME)
table CHILD (CHILD_ID, MOTHER_ID, MOTHER_NAME)
After a lot of transformations data are inserted into MOTHER table and I want to insert other fields of the data flow in CHILD table. To do this, I need the MOTHER_ID field that is auto incremented in MOTHER table.
My problem is to chain the insertion in CHILD table after the insertion in MOTHER table to be sure that the relative row in MOTHER table is really inserted. I haven't find any solution to chain another transformation task after my flow destination "Insert into MOTHER table".
The only solution I have found is to create a new flow control to insert data in CHILD table, using a lookup transformation task to bind with MOTHER table... But with this solution all my flow control transforms are made two times...
Is there a solution to chain two insertions with a foreign key constraint in a data flow?
We have an existing BI/DW process that adds large chunks of data daily (~10M rows) to an existing table, as well as using Deletes to remove stale data. This scenario seems to beg for partitioning to support switching in/out data.
After lots of reading on this, I have figured out the mechanics of the switching, bit I still have some unknowns about the indexes needed to support this.
The table currently has several non-clustered indexes, including one on the partitioning column - let's call that column snapshotdate. Fortunately there are no FKs involved, and no constraints.
Most of the partitioning material I see focuses on creating a clustered PK to assist with switching. Not sure if this is actually necessary, but assume I create one using an Identity column (currently missing) plus snapshotdate.
For the other non-clustered, non-unique indexes, can I just add the snapshotdate to the end of the index? i.e. will that satisfy the switching requirement?
I normalized the below tables but I am finding it difficult to copy data to the new tables. How do I copy data from existing table to the normalized tables? see the table structure below and other supporting information:
SKU_DATA(SKU,SKU_Description,Department,Buyer) Note: this table already has data in it. CREATE TABLE SKU_DATA ( SKU Integer NOT NULL,
[code].....
The table structure above have two three determinants( SKU,SKU_Description and Buyer). SKU and SKU_Description are candidate keys. Primary key is SKU.
1. I need to make use of in memory engine for my pr-existed develop procedures ,tables ,index. do I need and code changes for application and how to store tables /indexes in OLTP memory
Assume table index may have primary key index as well.
2. If table with one primary index and 2 foreign constraints, 3 non clusters indexed. which one able o load to memory area and how t do that.
3. In memory is lock free zone. usually locks will happpen in RDMS context . how this works without locks.
I'm new to my company, although not new to SQL 2005 and I found something interesting. I don't have an ERD yet, and so I was asking a co-worker what table some data was in, they told me a table that is NOT in SQL Server 2005's list of tables, views or synonyms.
I thought that was strange, and so I searched over and over again and still I couldn't find it. Then I did a select statement the table that Access thinks exists and SQL Server does not show and to my shock, the select statement pulled in data!
So how did this happen? How can I find the object in SSMS folder listing of tables/views or whatever and what am I overlooking?
I would like to export db tables to another server. I have try to use export feature but it will not exporting index triggers, constraint, etc. Is there any efficient way to export table data as well as other info?
Quick question, I hope, I am trying to create a table that has a column that is a nested table in SQL Server 2005 Express Edition. Any ideas how I could go about doing this?
