System.OverflowException: Value Was Either Too Large Or Too Small For An Int32.
Mar 23, 2008
System.OverflowException: Value was either too large or too small for an
Int32.
Why does this error originate in the following line?
"SqlCommand cmd = new SqlCommand("SELECT Count(*) FROM Contacts", conn)
........ ..........
DataSetContacts.ContactsRow row = ds.Contacts.NewContactsRow();
..................
row["ContactNumber"] = Convert.ToInt32(txtContactNo.Text);"
ContactNumber field is SqlDbType.Int.

when to use table variable and temp table. i told the interviewer that when rows is less like hundreds or thousand then use table variable else use temp table.After that he asked that what do u mean by less data or thousand rows may be there are multiple columns involved with that less rows and make a huge data set.

Hello,
the application will add items into a "bag". That is, the items in one table will refer a record in another table. This will be done in timely manner -- with second or minute delays between adding a new item. There will be up to thouthand of items per bag. The option is to wait until a full bag accumulates and set up all the references at once by using
UPDATE items SET container_ref = bag WHERE id IN [...]
The disadvantage of such all-at-once I see is inability to encapsulate the functionality into a SP -- the problem is to pass a set of IDs. The advantage should be efficiency in terms of total SQL Server load. How mush would it be?

Hi Experts
We are debating what is best:
1. To combine all the company's data in one large database, and use schemas and file groups to create logical and physical distribution on drives and namespaces
or
2. Distribute the data into smaller databases with related data - eg. products and product description in one db, Customers in another and orders and orderlines in a third db.
Just what are the pros and cons?
regards

HiThis is a question of "what does it cost me".Lets say I have an integer value which would fit into a smallint fieldbut the field is actually defined as int or even larger as bigint.What would that "cost" me ? How would definitions larger than I need forthe values in the field affect me ?Its obvious that the volume of the database would grow but with the sizeof resources etc that we have nowadays disc space isn't a problem likeit used to be and i/o is much faster and many people would tell me "whocares" , or IS it a problem ?How does it affect performance of data retrieves ? Searches ? Updatesand inserts ? How would it affect all db access if tables are pointingat each other with foreign keys ?Thanks !David Greenberg

HI There,
Generally speaking, is it better to use a large or small stripe size for a Raid 5 array (4 drives) ? I would appreciate any specifics also.
Thanks in advance.

Hi,
Please could you tell me how big sql tables are when people refer to them as small, medium and large? Preferably in terms of disk space or rows (each row in my table will contain a standard length job advert and 20 additional columns with an average of 8 characters)
Thanks for your help! :-)

I have a small number of rows in a dataset, Table 1. There is a CLOB on a large dataset, Table 2. They join on a PK. I would like to retrieve this CLOB and add it to the data flow for Table1. In short I want to emulate the following:
Table 1: Small table without CLOB, 10 rows.
Table 2: Large table with CLOB, 10,000,000 rows
select CLOB
from table2
where pk = (select pk from table1)
I want this to return the CLOBs for the small number of rows in Table 1. The PK is indexed obviously so it should be a fast look up.
Table 1 and Table 2 live on different Oracle databases. How do I perform this operation efficiently in SSIS? It seems the Lookup and Merge Join wont do this.

I'm using Decimal.MinValue in SqlParameter( SqlDbType.Decimal ) to execute a stored procedure.
But, I receive this stack trace exception:
System.OverflowException: Conversion overflows. at System.Data.SqlTypes.SqlDecimal.ToDecimal() at System.Data.SqlTypes.SqlDecimal.get_Value() at System.Data.SqlClient.TdsParser.AdjustDecimalScale(Decimal value, Int32 newScale) at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.InternalExecuteNonQuery(DbAsyncResult result, String methodName, Boolean sendToPipe) at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()
I have changed Decimal.MinValue to Decimal.Zero to resolve my trouble. But, Why Decimal.MinValue throw OverflowException? Isn't Decimal.MinValue valid SqlDbType.Decimal type?

Hi, all experts here,
Thank you very much for your kind attention.
It's so frustrated that I dont really knwo what is going on and why is that and I have tried ages to try to figure it out and nothing really helps.
I have already moved the data files of tempdb database to a drive with enough space (many GB space left still), but then again I got the problem which run out all of the system drive space when I run a query against a large table? Why is that? And how to figure it out?
Please help me and thanks a lot in advance for your kind advices and help and I am looking forward to hearing from you shortly.
With best regards,
Yours sincerely,

I have a well-structured but also very large binary data-set that is generated by a C++ application every five minutes. The data needs to be accessed by SQL applications. Since data is generated every five minutes, performance is key, both for write and read. The data set is about 500MB.If data is written to the file system, the write performance doesn't involve SQL server. For reading it, I have a CLR to read the portions of the data that I need based on offset and length. That works and is very fast. The problem is that data is stored in the file system, so it is not self-contained within the database.
A second option that I haven't explored yet, is to write the data into a table as VARBINARY(MAX). I would read the data using SUBSTRING with appropriate offset and length. Performance of SQL write/read of binary data of this size, and whether there is a third option I haven't thought off. I'm using SQL Server 2014.

Hi,
I found out that executing the procedure SP_INDEXOPTION and setting 'AllowRowLocks' to false i can prevent the sql server from locking rows in a table and 'AllowPageLocks' prevents from pages being locked. I need to preform same operation
in case of tables. I need to perform insertion operations concurrently and acquire required locks manually. Is there a way to stop sqlserver from acquiring locks on the table. I need to disable all the locks (row, page and table).
Thank you in advance.

Hello everyone,
This is my first time posting here, I hope this questions has not been asked before. I tried to search for it but I came not with nothing.
Recreating the error :
I am using VS2005. I created a Pocket PC 2003 project.
I have downloaded the SQL Server Compact Edition and installed it. I get the System.Data.SqlServerCe.dll file from the installation directory.
I reference to that DLL using Add Reference in VS2005.
Build it. In the Bin folder, a long list of files suddenly appears.
System.data.dll
System.data.oracleClient.dll
system.web.dll
system.enterpriseservices.dll
system.enterpriseservices.wrapper.dll
system.transactions.dll
and the rest of your original files in Bin
The worst of it all, all of these files are deployed into the Emulator! Causing it to run out of memory and unable to deploy.
Something is not right here, I just cannot figure it out! If this happens, each mobile devices can hold one applications. Thats not the way it should be, right?
If you have solved this before, do help. I am at my wits end at the moment.
Thanking you in advance.
Sincerely,
Lasker

Hi,
Can anyone help me figure out how to convert from type GUID to int32 format which will be the format to store in sqlserver database?
I have retrieved the UserId of a particular user in the current users profile (which is also a field in a row of data in table aspnet_Users) using this method:
MembershipUser user = Membership.GetUser(CreateUserWizard1.UserName);
and now would like to cast the following
user.ProviderUserKey type int32.
I thought the way to go was to use a GuidConverter by doing such as below by first assigning the user.ProviderUserKey in the _UserID variable and then calling:
TypeConverter converter = TypeDescriptor.GetConverter(_UserID);
Int32 newUserId = (Int32)converter.ConvertTo(_UserID, typeof(Int32));
But it blows up! any ideas?
thanks

Using c# in the compact framework, is there a way to do a parameterized query for counting the number of records where a specified column is null. I tried all of these, but none of them work:
cmd.Add(new SqlCeParameter("@IntColumn", SqlInt32.Null));
cmd.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.Add(new SqlCeParameter("@IntColumn", DBNull.Value));
cmd.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.Add(new SqlCeParameter("@IntColumn", SqlInt32.Null));
cmd.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";
cmd.Add(new SqlCeParameter("@IntColumn", DBNull.Value));
cmd.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Int32));
cmd.Parameters["@IntColumn"].Value = SqlInt32.Null;
cmdGetNumRead.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Int32));
cmd.Parameters["@IntColumn"].Value = SqlInt32.Null;
cmdGetNumRead.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Int32));
cmd.Parameters["@IntColumn"].Value = DBNull.Value;
cmdGetNumRead.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Int32));
cmd.Parameters["@IntColumn"].Value = DBNull.Value;
cmdGetNumRead.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Variant));
cmd.Parameters["@IntColumn"].Value = SqlInt32.Null;
cmd.CommandText = "select count(*) from Meter where IntColumn is not @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Variant));
cmd.Parameters["@IntColumn"].Value = SqlInt32.Null;
cmd.CommandText = "select count(*) from Meter where not IntColumn = @IntColumn";
md.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Variant));
cmd.Parameters["@IntColumn"].Value = DBNull.Value;
cmd.CommandText = "select count(*) from Meter where IntColumn is not @IntColumn";
cmd.Parameters.Add(new SqlCeParameter("@IntColumn", SqlDbType.Variant));
cmd.Parameters["@IntColumn"].Value = DBNull.Value;
cmd.CommandText = "select count(*) from Meter where not IntColumn = @IntColumn";
Whenever I use a "is not" in the query I get an exception, otherwise it returns a count of 0 which is not accurate. Any help will be appreciated.

I have created a windows library control that accesses a local sql database
I tried the following strings for connecting
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"
Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"
I am not running the webpage in a virtual directory but in
C:Inetpubwwwrootusercontrol
and I have a simple index.html that tries to read from an sql db but throws
the error
System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
at System.Security.CodeAccessSecurityEngine.Check(Object demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.PermissionSet.Demand()
at System.Data.Common.DbConnectionOptions.DemandPermission()
at System.Data.SqlClient.SqlConnection.PermissionDemand()
at System.Data.SqlClient.SqlConnectionFactory.PermissionDemand(DbConnection outerConnection)
at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection,
etc etc
The action that failed was:
Demand
The type of the first permission that failed was:
System.Data.SqlClient.SqlClientPermission
The Zone of the assembly that failed was:
Trusted
I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security
I think that a windows form connecting to a sql database running in a webpage should be simple
to configure what am I missing?

HelloI have a case where Partners are some kind of Super-Users and arestored in a SQL Server database. Best is IMO to put both in the sametable:table Customers:CustomerID[pr.key][blabla]PartnerIDBut of course I have to reference the partnerid from another table andI want SQL Server to maintain the integrity rules. I could splitCustomers en Partners into different tables, but that would not bewise i think.Or I could just reference the CustomerID from the other table and-know- that we are talking about a partner, but in that case it itpossible to reference a customer that is not a partner, and i want toavoid that.Any ideas?Freek Versteijn

Consider a recordset consisting of
Vendor, Invoice, InvAmt, Item,ItemAmt
1, 'A12345', 100.00,'Item1', 25.00
1, 'A12345', 100.00,'Item2', 50.00
1, 'Z22222', 200.00,'Item1',100.00
1, 'Z22222', 200.00,'Item3', 50.00
2, 'A12345', 300.00,'Item4,' 250.00
I have a report that groups by vendor and then by invoice within a vendor.
I want to create a report totals that contains
Number of vendors=2
Number of invoices=3
Total Inv Amounts=600.00
Total Item Amounts=475.00
How?
Number of vendors is =count(distinct vendors) ??
Cant do that for # Invoices because of possible duplicate invoices used by different vendors.
How do i get the total invamt? Each occurrence of the invamt fld is in a list2 as =first(invamt).
I really need the sum of each first(invamt).
Thanx Up Front.

I currently use JET 4.0 as my database in a small app I distribute. SQL Server Express is way way too big to distribute. I am looking to move to a better database.
Is there a version of SQL that gives simple database CRUD support, but is super small to distribute? I am also considering Firebird as it's a full database and only 3MB on the client as an embedded tool.
