Easier Method To Remove And Add A Table To Database?
Feb 22, 2000
I have a table that is corrupted and want to remove and add a backup version of it. How can i remove this table and add it again preserving all the foregin key restraints, permissions, dependencies, etc? Simply exporting and importing does not work. I could painfully remove the table and then painfully reconnect it again, recreating all the foreign key restraints, etc, by hand; but there has to be an easier way! What is the How-to?
I am using the Database is Oracle SQL Developer, here the Requirement is like Before insert the values in Database I need to remove the Database table and insert new values.
DELETE FROM XXMBB_NOSVOS_TMP_VO_NO WHERE EFFECTIVE_DATE BETWEEN '01' || '-' || TO_CHAR(to_date(:N_Date,'DD-MM-YY'),'MON-YY') AND to_date(:N_Date,'DD-MM-YY') AND LEDGER_ID = LED and name_rdf='NOSVOS'; COMMIT; DELETE FROM XXMBB_NOSVOS_BAL_TMP_VO_NO WHERE PERIOD_NAME = TO_CHAR(add_months(to_date(:N_Date,'DD-MM-YY'),-1),'MON-YY')
I have a database with table representing city blocks, houses, and people. On my main aspx page, I have a datagrid which displays a list of the blocks, followed by a count of the houses in each block, followed by a count of the people in each block. Right now I have something that works, but it is awful. Every time the page loads it makes a ton of connections to the database, and I have convoluted spaghetti code. Now I need to add more functionality, but I can't rightly do that until I find a more efficient way to do this.Step one. The program connects to the database and gets a list of the blocks using the statement "SELECT blockid FROM blocks"Step two: The program iterates through each blockid in the list and executes the statement "SELECT houseid FROM houses WHERE blockid = (whatever)"Step three: The program counts the rows returned from step two to determine the count of how many houses are in that block. Step four: The program iterates through each houseid from step two and exectues the statement "SELECT COUNT (personid) FROM people WHERE houseid = (whatever)" the result is added to a variable that keeps a running count.Step five: the final value of the variable in step four is the number of people in that block.My question for you is, how can this be done more efficiently? Can I group together some awesome SQL statement that will get these counts? I thought about doing something like "SELECT blockid (SELECT COUNT houseid FROM houses WHERE blockid = something) as HouseCount" but I can't figure out how I could take the value in the first column (blockid) and pass it to the inner select statement.Any thoughts on how to make this better? Below is the full code for my function, in case you want to examine in more detail. Also, I am in the process of changing the select statements into stored procedures, so don't beat me up too badly over that bit of ugliness in my function. Thanks.Private Function GetBlockDataSet() As DataSet Dim myconnection As SqlConnection Dim objDataAdapter As SqlDataAdapter Dim query, connectionstring As String Dim tempDS As New DataSet Dim houseDS As New DataSet Dim peopleDS As New DataSet Dim DC1 As New DataColumn Dim DC2 As New DataColumn Dim i, j, peoplecount As Int32 Dim DR, DR2 As DataRow query = "SELECT blockid FROM blocks" connectionstring = configurationsettsing.appsettings("ConnectionString") myconnection = New SqlConnection(connectionstring) objDataAdapter = New SqlDataAdapter(query, myconnection) objDataAdapter.Fill(tempDS, "BlockList") DC1.DataType = System.Type.GetType("System.Int32") DC2.DataType = System.Type.GetType("System.Int32") DC1.ColumnName = "HouseCount" DC2.ColumnName = "PeopleCount" tempDS.Tables("BlockList").Columns.Add(DC1) tempDS.Tables("blockList").Columns.Add(DC2) i = 0 For Each DR In tempDS.Tables("BlockList").Rows query = "SELECT houseid FROM Houses WHERE blockid = '" query &= tempDS.Tables("BlockList").Rows(i).Item(0) query &= "'" objDataAdapter = New SqlDataAdapter(query, myconnection) objDataAdapter.Fill(houseDS) tempDS.Tables("BlockList").Rows(i).Item(1) = _ houseDS.Tables(0).Rows.Count tempDS.Tables("BlockList").Rows(i).Item(2) = 0 j = 0 peoplecount = 0 For Each DR2 In houseDS.Tables(0).Rows query = "SELECT COUNT (personid) FROM people WHERE HouseID = '" query &= houseDS.Tables(0).Rows(j).Item(0) query &= "'" objDataAdapter = New SqlDataAdapter(query, myconnection) objDataAdapter.Fill(peopleDS) peoplecount += peopleDS.Tables(0).Rows(0).Item(0) j = j + 1 peopleDS.Clear() Next tempDS.Tables("BlockList").Rows(i).Item(2) = peoplecount houseDS.Clear() i = i + 1 Next GetBlockDataSet = tempDS ' Here comes the garbage collection myconnection.Close() myconnection.Dispose() myconnection = Nothing objDataAdapter.Dispose() objDataAdapter = Nothing tempDS.Dispose() tempDS = Nothing houseDS.Dispose() houseDS = Nothing peopleDS.Dispose() peopleDS = Nothing DC1.Dispose() DC1 = Nothing DC2.Dispose() DC2 = Nothing
Hi-I have a sql server database, and am wring web apps to access it.I've created databases different ways, and ended up with different owners (eg dbo, nt authorityetwork services...)I also have connection strings using windows authentication, and some using a user name and password.I have read that using windows authentication is the best way to go, as far as security goes, but I have noticed some connectivity issues when I upload the site to the server, and test it remotely. What is the safest 'owner' of the database, and what's the safest way to connect?Thanks Dan
I just finished a lengthy process (for me) of writing this cursor that gets each row from the Fact table, and creates a running total of the billable hours (hours from rows where BillableType = 1). It starts over when the month changes, the year changes, or the employee changes.
I did this again for a running total of billable hours for the year.
I put these in 2 stored procedures and run them in an Execute SQL control flow task in my SSIS package. It seems like SSIS is designed to make this kind of procedure simpler, and I'm wondering if I'm doing this in the best way, or if there's a more efficient way to do this using tasks inside SSIS. Can anyone advise? Any help is greatly appreciated.
Best, Andy
Don't feel obligated to read this cursor if you understand the problem above. It's not color coded because when I copied it from SQL I lost the tabbing on the case expressions.

Hi,I am trying to write a method which needs to call a stored procedure and then needs to get the response of the stored procedure back to the variable i declared in the method. private string GetFromCode(string strWebVersionFromCode, string strWebVersionString) { //call stored procedure } strWebVersionFromCode = GetFromCode(strFromCode, "web_version"); // is the var which will store the response.how should I do this?Please assist.
I have a table load which has load value for each hour.ie load_1,load_2...load_24... I want to find the max value between the 24 hourly loads and assign it to a variable say load_max...
These are the 24 load values with the load _id I have lots of rows with load_id starting from 1- 100 Output should be to display the load_Id,load_max, load_min for each row...(after comparing the 24 loads with each other) How can I do it with sql server.
I've here a shell plugin and it's compiling fine and can be viewed in BI Dev Studio when choosing the DM technique using the proper wizard.
I also have here a K-Means implementation that estimates the number of clusters using a statistical semi-empiric index (the PBM index).
This implementation is done in C# and works fine. But it has to receive all the data of the database (all variables for each row) in order to do the proper vectorial calculations in a CSR (Compact Sparse Rows) way.
Besides, as you know, K-Means needs all the data at once because of the clusters mean (centroid) calculation.
So, I have some questions:
1) Where to place the call to the K-Means implementation in the shell passing as argument an object holding all the data ?
2) After this call, with the data clustered, what other objects must be modified in order to use Microsoft Cluster Viewer ?
3) I will need to create a new column or a new table on the database to specify which data belongs to which cluster. Can I open an ADO connection as I normally do in other programs from inside the plugin or is there another (easier/better) way to do so ?
i get just as frustrated each time i try to configure email alerts on failed jobs on ms sql, it is beyond me why microsoft couldn't just let you point out an SMTP server to send through and be done with it.
is there a way to avoid having to setup an email client on our sql 7 and 2000 servers through some 3rd party app or other simple solution?
I have a Sql Server 2005 database with many tables, each with millions of records within them.
They all have a Receive Date field, with records going back 10 years or so.
What would be the best way to partition it? I was thinking of partitioning them by years, but that would give me 10+ partitions -- would that be alot of overhead?
I€™m using the data adapter method FillSchema works fine in MS Access but SQL Server Express Edition it doesn€™t get the primary key of the table. For example if I try to use the Find method of the dataset I get this error €śTable doesn't have a primary key€? but in MS Access these do not happen.
This is the code that I€™m using: Dim sql As String = "SELECT admin.rents.id, admin.rents.transaction_id, admin.rents.item_id, admin.rents.description, admin.rents.due_date, admin.rents.return_date, " sql &= "admin.rents.amount_to_pay, admin.rents.paid_amount, admin.rents.tax, admin.rents.type, admin.rents.deposit_id " sql &= "FROM admin.rents INNER JOIN " sql &= "admin.transactions ON admin.rents.transaction_id = admin.transactions.id " sql &= "WHERE admin.transactions.customer_id=?; "
RentsDA = New OdbcDataAdapter(sql, cn) With RentsDA.SelectCommand .Parameters.Add(New OdbcParameter("@customer_id", OdbcType.Int)).Value = TextBox1.Text.Trim End With RentsDA.FillSchema(ds, SchemaType.Source, "Rents") RentsDA.Fill(ds, "Rents")
It's because of the joins? I need to configure something in the sql server? What is the problem?
Dear AllI am very new to MS SQL Server and I am wondering is there some toolwhich would allow me to build pivot tables in SQL more easily. At themoment writing a query can be quite challenging and difficult.Is there any software which allows you to do it more intuitively andgives you some visual feedback about query you are building?I would be very grateful for any help with this.wujtehacjusz
I'm trying to figure out what solution (replication, mirroring, clustering) would work best for me.
I have been reading many articles in BOL and in this forum. Most talk about getting data TO a backup/standby/subscriber, but I can't find a lot of info regarding getting the data BACK after a disaster is over.
We have a main office and a disaster recovery facility. Most of the time there are no data updates at the disaster location. So, I need to get data to the disaster facility via WAN (latency is not a huge issue - end of day syncing is fine) for backup purposes. In the event of a disaster, the main office will be offline and data changes will happen at the disaster site. When the disaster is "over" and we return to the main office, what's the best scheme to reverse the data back to the main office to start business again? We are a financial company, and have gigabytes of relatively static data. Most changes are current day. So, to snapshot a 100GB database when I know only a few hundred MB changes a day doesn't seem feasible to me.
Most replication scenarios (at least from what I see) can't easily "reverse" the replication after a disaster situation. I'm looking at merge replication on a schedule which seems to look good, but was wondering if anyone else has any ideas or suggestions?
I'm trying to select from a table with three columns. I want these columns to be spread out among multiple columns based on the values. I hope someone can shed some light on this. I might be able to use pivot, but don't know how the syntax would roll for this.
Here is the example of dummy values and the output I am trying to obtain.
drop table table1
create table table1
(Category int, Place int, Value int)
insert into table1 values
(1, 1, 20)
insert into table1 values
(1,2, 12)
insert into table1 values
(1,3, 30)
insert into table1 values
(2,1, 34)
insert into table1 values
(2,2, 15)
insert into table1 values
(2,3, 78)
select Category,
(select top 1 value from table1 where place = 1 and Category = t1.Category) as place1,
(select top 1 value from table1 where place = 2 and Category = t1.Category) as place2,
(select top 1 value from table1 where place = 3 and Category = t1.Category) as place3
I have a bit of brainteaser that's going to take some serious thought.
I'm importing information from .xls files into a SQL table. The problem is I need to check for dupes and increment certain fields on success of dupe find and then not insert or delete the dupes.
For example, if I have Adam, Turner, 32, 50 already in the table and someone tries to insert Adam, Turner, 32, 50...I need it to increment to read Adam, Turner, 64, 100 and not insert the record. (Notice 2 fields were incremented.)
With that, I have created an INSERT trigger as follows:
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER Trigger [dbo].[trgInsertCheck] ON [dbo].[MyTable] FOR INSERT AS BEGIN EXEC sp_UpdateDupes EXEC sp_DeleteDupes END
The first stored procedure checks for dupes and updates if any dupes are found as follows: --------------------------------------------------------------------------------------------------------------------------------------
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER Procedure [dbo].[sp_UpdateDupes] AS
DECLARE @FirstName varchar(20), @LastName varchar(20), @Age int, @Widgets int DECLARE c1 CURSOR FOR
SELECT FirstName, LastName, Age, Widgets FROM MyTable GROUP BY FirstName, LastName, Age, Widgets HAVING COUNT(*) > 1
OPEN c1 FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets WHILE @@FETCH_STATUS = 0 BEGIN
UPDATE MyTable set Widgets = Widgets + @Widgets, Age = Age + @Age WHERE FirstName = @FirstName AND LastName = @LastName
FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets END CLOSE c1 DEALLOCATE c1
Lastly, it finds all dupes, deletes them and inserts one row back in as follows: --------------------------------------------------------------------------------------------------------------
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO ALTER Procedure [dbo].[sp_DeleteDupes] AS
DECLARE @FirstName varchar(20), @LastName varchar(20), @Age int, @Widgets int --declare all fields in table
DECLARE c1 CURSOR FOR
SELECT FirstName, LastName, Age, Widgets FROM MyTable GROUP BY FirstName, LastName, Age, Widgets HAVING COUNT(*) > 1
OPEN c1 FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets WHILE @@FETCH_STATUS = 0
BEGIN --Delete all dupes...the cursor remembers the current record
DELETE FROM MyTable WHERE FirstName IN (SELECT FirstName FROM MyTable GROUP BY FirstName HAVING COUNT(FirstName) > 1) AND LastName IN (SELECT LastName FROM MyTable GROUP BY LastName HAVING COUNT(LastName) > 1) AND Age IN (SELECT Age FROM MyTable GROUP BY Age HAVING COUNT(Age) > 1) AND Widgets IN (SELECT Widgets FROM MyTable GROUP BY Widgets HAVING COUNT(Widgets) > 1)
--insert the current record back into the table
INSERT INTO MyTable(FirstName, LastName, Age, Widgets) VALUES(@FirstName, @LastName, @Age, @Widgets)
FETCH NEXT FROM c1 INTO @FirstName, @LastName, @Age, @Widgets END CLOSE c1 DEALLOCATE c1
Is there an easier way to do this?
(I know Age doesn't make much sense in this example but just replace it with a field would logically be incremented such as wadgets.)
I have a DataSet which I am holding in .NET and I would like to know the quickest way to get the DataSet in to a Table on SQL Server? Any sample code would be great.
Hi, I just have a Dataset with my tables and thats it I have a grid view with several datas on it no problem to get the data or insert but as soon as I try to delete or update some records the local machine through the same error Unable to find nongeneric method... I've try to create an Update query into my table adapters but still not working with this one Also, try to remove the original_{0} and got the same error... Please help if anyone has a solution
Hi,I have a table which I need to store times in. What is the best way of doing this? The only way I can think of so far is to save the times as a datetime such as '1/1/1900 03:00 PM' then format the date as "hh:mm tt" so that the day isn't displayed. Is this the best method?Thanks,Curt.
Lets assume database A is production, B is copy. SQL Server 2005 sp2, SQL CE 3.5
Database A has a variety of transactions against it 24x7 Database B (the copy) is for reporting and as a source of merge replication for SQL CE instances Merge replication and reporting is used 24x7 as well
I have the following requirements: Maintain an up to date copy of the production database (need not be up to the minute, could be hourly, even daily update) Database B is read-only. The merge replication is NOT bi-directional.
Here is the caveat (which I think prohibits using some solutions to this problem): The production application accomplishes much of it's functionality with in-memory copies of records. I have no control over the production application. When it works against the database, it sort of does a 'withdrawal-deposit' scenario. (to the best of my knowledge it's not using SQL Server transactions) So, for every record it works with, a copy is made out of the database, changes are made in memory, a delete of the database record is done, then the record is re-inserted.
With this kind of behavior in db A, I'm not sure what it would do to log-shipping or transactional replication. I do know that I want to minimize the changes required at the SQL CE instances to keep the sync operation to a minimal cost.
I need a SSIS Package that compares the two tables and removes the rows in the first table with keys that do not exist in the second table. For example....
I have a table of returns based on returnID. In another table I have returnErrors that are based on returnID as well. I want a package that will uses my returns table as a source and compares that dataset to the dataset of the returnError and remove or spilt the data so that my remaining dataset only has returns that have returnErrors. I can do this in T-SQL, but I am looking for a SSIS solution that uses the conditional split transformation or some other transformation(s) combinations.
From what I've read in the docs, ado.net currently supports opening sqlserver ce tables in table-direct mode and performing Seek operations on them(using SqlCeDataReader), but not on the full-blown sql server. Is this(will this be) still true with ado.net 2.0 & sql server 2005?
I have a process that restores a backup from a primary server to a backup server daily. When doing the restore, sometime it fails (for various reasons).
I have coded a job to Set offline, set online, an then do the restore:
RESTORE DATABASE [xxx] FROM DISK = N'D:Backup Stagingxxx.bak' WITH FILE = 1, NOUNLOAD, REPLACE, STATS = 10
Sometimes it fails to bring back online, other errors as well. Is there a reliable method of doing this?
I wanted to set up a mechanism that would transfer blocks of records (a few dozen to in rare cases a few thousand), with slight modification, from one database to another. It's a sort of custom partial archiving process that would be triggered from a web-based admin application in plain old ASP (not .net alas). Records in the target db would be identical except:
-- the primary key in the source table, an identity field, would be just an integer in the target table -- the target table has an extra field, an integer batch ID supplied by the web application that triggers the process
It's a simple, if not efficient matter to do it within the web application: query the source table, suck the records into memory, and insert them one by one into the target db. This will be an infrequent process which can be done at off-hours, so a bit of inefficiency is not the end of the world. But I wondered if there is a more sensible, orthodox approach:
-- Could this process be done, and done efficiently, as a stored procedure with the batch ID passed as a parameter? -- Is there any way to do a bulk insert from a recordset or array in memory using plain ASP, ADO and SQL? And if so, is that better than inserting records one by one?
I realize that the ASP.NET tableadapter and dataset features might provide a good solution, but in the short run I can't rewrite the whole application. Advice on the best general approach from an ASP-ADO platform would be appreciated, and I will try to figure out the details.
Hi,I'm writing a telecom billing system where it is necessary to import csv delimited files into a sql server table. 1) The csv files to import differ in column arrangement i.e SQL server table arrangement = A, B, C, D whilst CDR = - , A, -, C, D2) The csv files are delimited via different characters i.e some are del.. by commas some by semi colons I can import a CSV file from my application using a BULK INSERT query but only using CSV that resembles the structure of the table exactly How can I pass a CSV to the table and state where I want each CSV column to fill a column in the SQL SERVER table Below is how I am managing to pass a CDR to the SQL table that I have pre manufactured to resemble the structure of the SQL table Is there a way I can state which values from the CSV I want to pass to corresponding columns in the SQL table:
string conString = @"Provider=SQLOLEDB;Server=(local);Database=Billing;Uid=sa;Pwd=sa;"; for (int i = listBox1.Items.Count - 1; i >= 0; i--) { string strSQL; OleDbConnection objConnection = null; OleDbCommand objCmd = null; objConnection = new OleDbConnection(conString);

I am trying to use the ListChildren method to query the SSRS Catalog. I am using this as a dataset in a report. I'd like to see more columns, in particular the Description column, included in the dataset. Is there some way to tell ListChildren what columns should be included or is there some other method to obtain this information. ListChildren returns ID, Name, Path, Type, CreationDate, ModifiedDate, CreatedBy, ModifiedBy, xmlns.
I'd prefer not to query the Catalog table directly.
I developed a console application that will continually check a messagequeue to watch for any incoming data that needs to be inserted into MSSQL database.What would be a low-cost method I could use inside this consoleapplication to make sure the MS SQL database is operational before Iperform the insert?
