How To Retrieve All Information Abt All Constraints Inorder To Drop And Recreate Them
May 25, 2004
Hello,
I need to retrieve all the information about all the foreign key constraints,inorder to store them temporarily (to be deleted later)and then recreated after making the necessary modifications to the concerned tables.
The stored proc sp_helpconstraint shows all the constraint types, their user-defined or system-supplied name, the columns on which they have been defined, and the expression that defines them.But I don't know whether it can be manipulated to get what I want.I need to get it done programmatically..so that I can integrate it in my program which I'm building up progressively.
Any help or scripts would be appreciated!
I need to drop and recreate few subscriptions in transactional publication Do I need to worry about log marker issues ? Do I need to set the primary and replicate databases in 'DBO use only'
The Primary and Replicate databases are being accessed all the time.
I have come across a user that has error 2525 errors on sysobjects tables throughout their SQL 6.5 system. The ids match and I can identify the index. But as they are system tables I cannot drop or rebuild the indexes.
Any ideas please?
The errors have been occuring for some time, so it is not an option to restore. I would like to avoid having to transfer data to and from another SQL Server.
I'm having a heck of a time trying to upload data to an excel spreadsheet. This works perfectly in sql 2000 but I've been having problems with 2005

I have found an (encrypted) SP which takes ~20 seconds to run on one of our client DBs.
If I drop and recreate (or alter) the SP giving it the same contents it will run in ~1 second.
I need to know 1. why the sp started running so slowly 2. how to stop it happening again 3. how to fix it without resorting to drop/recreate (I can't exactly write a batch script to recreate all our sps every so often)
I have tried sp_updatestats and sp_recompile before running the sp to no avail...
I have two tables Person & Location where Location has a primary key LocationId and Person has a foreign key LocationId.
Sometime ago I used the Database Diagrams visual tool of SQL Server Management Studio Express to create the foreign key relationship between the two tables - i.e. "visually" (drawing a line between the PK & FK LocationId elements of both tables).
Time has passed and I recently noticed that, upon retrieving my saved diagram, the foreign key relationship had "fallen off" (i.e. the many-to-one line was no longer showing in the diagram).
After recreating the relationship (redrawing the line) I find that I get an error message when I try to save the diagram:
Post-Save Notifications [!] Errors were encountered during the save process. Some database objects were not saved.
'Location' table saved successfully 'Person' table - Unable to create relationship 'FK_Person_Location'. The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK_Person_Location". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
When I go back to the object explorer and view the dependencies for the two tables, there is no dependency (between these two tables) revealed. When I try to create the foreign key constraint manually (T-SQL) it again says can't add the constraint. It comes up with an error as follows:
ALTER TABLE Person ADD FOREIGN KEY (LocationId) REFERENCES Location (LocationId)
Msg 547, Level 16, State 0, Line 2 The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "FK__Person__LocationId__793DFFAF". The conflict occurred in database "mydb", table "dbo.Location", column 'LocationId'.
(Note: Each time I do this, the 8 hexadecimal character suffix changes.)
When I try to drop the foreign key:
alter table Person drop constraint FK__Person__LocationId
it comes back with the error:
Msg 3728, Level 16, State 1, Line 2 'FK__Person__LocationId' is not a constraint. Msg 3727, Level 16, State 0, Line 2 Could not drop constraint. See previous errors.
So it seems that there's some kind of goof up here. Can anybody shed light on this / tell me how to fix it?
Hi folks, Wonder if I'm onto something....everything I've read says that to drop foreign key constraints, you have to drop/recreate the table.
I've been able to dynamically create the ALTER TABLE statements for all FK constraints in a database. The way I did was a little convoluted (Access 97 linked tables and pass-through queries, cut/paste from the debug window to SQL7 QA), but it does work. More importantly, it saves the hassle of dropping/recreating tables....Someone with more expertise than I in using nested cursors could probably convert it to pure T-SQL pretty easily.
Just curious...opinions? Be glad to post the code here if that's appropriate.
I remember once using a command in Query Analyser that gave me all theinformation about a table. It showed details about the columns,constraints, keys, indexes etc.I can't remember how I did this? Can anyone help me?It could of been a stored proc that I called or a query on the systemtables.I do know that it was very simple to do and it was executed in QueryAnalyser.Can anyone help me?
I have a report and it retrieves information from an etl logging table which contains this info: etl_process_name, active_since_date, last_run_date.
When the packages are executing, the table cant be queried because it is in a transaction. Therefore the report keeps generating :s The thing I want is that: If I query that table (with the report to show the logging table information) and the packages are executing, I want to see the values of the table before the transaction.
What I tried: From sql management studio:
ALTER DATABASE MyDataBase SET ALLOW_SNAPSHOT_ISOLATION ON set transaction isolation level snapshot go SELECT etl_process, last_run, active_since FROM config.etl_settings
I did this while the packages were executing and it works but it won't work when I execute the same SELECT statement from the Dataset in the report. How is that possible? Does it have something to do with setting the database options for all users?
Additional info: I'm database owner The report solution has a shared datasource which refers to the same database
I am testing Insert, Update etc. and messing up my database with "dirty" data. Is there a way to temporarily drop FOREIGN KEY constraints to truncate a table after testing without dropping the whole table and rebuilding it? Newbie

Hi, I'm getting this error [Microsoft][ODBC SQL Server Driver][SQL Server]Could not retrieve replication information for table 735393739. Verify that the table has a primary key, and then rerun the Log Reader Agent.Please help me!
I am attempting to drop a database (sales), however I receive this message: Error 3274 is "Cannot drop the database 'sales' because it is published for replication." Yet, I no longer have any publications in this database. It seems that there is some orphaned information related to a publication that existed. Any help would be great.
I am in process of transfering data from Sybase to Sql Server using SSIS 2005
have taken a Data Flow Task in Control Flow tab
In Data flow tab, I have taken one Ole DB Source and One OLe DB Destination
For the source, I am using Sybase Adaptive Server Anywhere Provider 8.0
For Destination, I am using Sql Server 2005 database
In Ole Db Source Editor , For OLe Db Connection Manager, I choose Sybase Connection For Data access mode, I choose Table or View For Name of the table or the view, I choose a table by name Table1( it lists all the tables from Sybase database)
When i click on preview button or Columns link, I get the following Error
Error at Data Flow Task [OLE DB Source [1]]: An OLE DB error has occurred. Error code: 0x80040E21.
Error at Data Flow Task [OLE DB Source [1]]: Unable to retrieve column information from the data source. Make sure your target table in the database is available.
Hi, I am working on inserting information into a DB and then retrieving the ID created for that Data to use elsewhere in my code. I have the code below but I do not know how to get toOutput parameter. Can anyone please help?

Till recently we were using the following code to retreive schema information of columns of tables
Dim schemaTable = connection.GetOleDbSchemaTable( _ System.Data.OleDb.OleDbSchemaGuid.Columns, _ New Object() {Nothing, Nothing, tableName, Nothing})
Now instead of getting the name of table (which i was using as param for filtering) i'm going to receive a sql-query. Now my question is if I were to get a query like the following :
I am trying to set up a data flow task. The source is "SQL Command" which is a stored procedure. The proc has a few temp tables that it outputs the final resultset from. When I hit preview in the ole db source editor, I see the right output. When I select the "Columns" tab on the right, the "Available External Column List" is empty. Why don't the column names appear? What is the work around to get the column mappings to work b/w source and destination in this scenario.
In DTS previously, you could "fool" the package by first compiling the stored procedure with hardcoded column names and dummy values, creating and saving the package and finally changing the procedure back to the actual output. As long as the columns remained the same, all would work. Thats not working for me in SSIS.
Hello, I am getting very frustrated! I have got a Foreach loop container which I am processing files within a folder. I have a flatfile connection manager which I have set up using a test file and have updated the expressions attribute to be the package variable I set up in the collection for the loop container however everytime I run it I get the error: 0xC0202094 cannot retrieve the column information from the flatfile connection manager. I can only guess that it is either the variable being passed to the connection manager or the way I set up the connection manager. When I msgbox the variable in a script component before the dataflow step, the variable for the file seems fine. Any suggestions are REALLY appreciated.
I've developed a package that is working well at development machine from VS 2013 for a sample flat file. Also, over development machine, I've deployed it to SSISDB catalogue and even from there also it is running well for the same file.When the same package is deployed to production server's SSISDB catalogue database, it throws following error while processing the same sample flat file, “Unable to retrieve column information from the flat file connection manager”
I know this is probably a flick of a switch but I cannot figure out which switch. Setup is SQL Server / Stored Procedures / DAL / BLL(skipped for testing) / PL. The stored procedure queries from only one table and two columns are ignored because they are being phased out. I can run the stored procedure and preview the data in the DAL but when I create a page with an ODS linked to the DAL and a GridView I get this error. I checked every column that does not allow nulls and they all have values. I checked unique columns (ID is the only unique and is Identity=Yes in the table definition). I checked foreign-key columns for values that are not in the foreign table and there are none. Any ideas why do I get this? Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
Hi, I am getting the above error when trying to load a report into my Web Application, I have tracked the error down to one specific field in my database. Even though this field is a NVarChar field and is of size 30 it would seem that there is an issue returning the value from the field. I can write it into the database no problems but when I try to get it out of the database it returns the above error. e.g MOB 401.908.804 - Fails 0401.907.324 - okay 8239 9082 (pager) - fails Anyone got an idea on how to fix this???? Regards.. Peter.

I need a stored procedure that can drop and recreate any table in a DB.
How could I find out all information pertinent to a table and able to generate the create statement dynamically in the preocedure then drop it and recreate the table.
I want to drop table and then recreate. It's referenced by many table and I dont want to drop all constraints referencing to it. Is there any feature like "switch off/on constraints" in MSSQL?(6.5)
Does anyone know how to recreate a database from a log file? Here is the situation:
I had a server go bad. The drive configuration was as follows
Server OS on separate RAID controller - RAID Level 1 SQL Data on separate RAID controller - RAID Level 5 Transaction Logs on Separate Raid Controller - RAID Level 1
I lost the RAID 5 array and can't get it back and don't have a backup. I need to know if/how I can recreate the database from the log file. The log file has been set to grow and has never been purged so I am hoping that I can recreate the database from scratch. Is this possible?
Dear All, after searching continuously for removing the suspect mode of MSDB database, i've found a great article in net.but i dont understand how to proceed. please explain me the steps....
1.Detach the damaged msdb. You can't just detach msdb because you're not allowed to detach system databases. However, you can if you start the server with trace flag 3608. I did this by shutting down the server, navigating to the directory 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBinn' and doing the following: start sqlservr.exe -c -T3608 2.Move or rename the damaged msdb files (msdbdata.mdf and msdblog.ldf in the 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLData' directory) 3.Run the instmsdb.sql script in the 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLInstall' directory 4.Shutdown and restart the server without the 3608 trace flag

I want to create a clean copy of my DB now that it is done. So it can be moved to another Server. It has some sample data in some tables that I would like to keep and some in other table that I don't. How can I do this?
Due to a server move of our SQL databases something 'strange' happend: one of the login accounts disappeared.
When I try to recreate it, SQL gives me back an error stating the account already exists. Read something about loginaccounts becoming orphaned but don't know how to solve it. The login account is a Windows (AD) account and not a SQL account (both requiring different methods of fixing?). How can I recreate just this single account?
I am trying to recreate a MySQL database on a new domain. The original database was exported into about 40 .SQL text files. I am importing these .SQL text files into a new database using phpmyadmin. When I attempt to import the first of these files, I get a "fatal error". It says the upload time has exceeded the 300 second limit. How do I set up the server so there is no upload time limit? Or how would you approach a solution to this problem? There are about 40 of these text files and each file varies in size between 5 and 15mb. Is it possible to split individual files in half or 3 parts and import that way? Any help would be greatly appreciated. Thanks!!
