I have a fairly complex set of statistical views and when I try to combine them together into one "master" view, I get the following error:
Msg 4408, Level 19, State 1
The query and the views in it exceed the limit of 16 tables.
I have not been able to find anything in books online or the kb addressing this issue. Is there a way to increase this limit? The first question I had of myself is, "Is there a way to make the view and underlying views more efficient?" But I have been coding sql for years now and I do not think there is much of a way to reduce the number of tables. It is just a darn complex query!
Any help beyond "simplify your sql statement" would be of great help.
I create an sql string as so, add parameters to it and execute it: string cmdstr = "INSERT INTO locations(id1, id2, companyname, address, city, province, postalcode, phonenumber, faxnumber, contact, contactemail) VALUES (@id1,@id2,@companyname,@address,@city,@province,@postalcode,@phonenumber,@faxnumber,@contact,@contactemail)"; SqlCommand sqlCmd = GetCommandSQL(cmdstr); sqlCmd.CommandTimeout = TimeOut; sqlCmd.Parameters.Add("@id1", SqlDbType.Int).Value = itID; sqlCmd.Parameters.Add("@id2", SqlDbType.Int).Value = Convert.ToInt32(ddlDPCLocation.SelectedValue); sqlCmd.Parameters.Add("@companyname", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbCompanyName")).Text; sqlCmd.Parameters.Add("@address", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbAddress")).Text; sqlCmd.Parameters.Add("@city", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbCity")).Text; sqlCmd.Parameters.Add("@province", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbProvince")).Text; sqlCmd.Parameters.Add("@postalcode", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbPostalCode")).Text; sqlCmd.Parameters.Add("@phonenumber", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbPhoneNumber")).Text; sqlCmd.Parameters.Add("@faxnumber", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbFaxNumber")).Text; sqlCmd.Parameters.Add("@contact", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbContact")).Text; sqlCmd.Parameters.Add("@contactemail", SqlDbType.VarChar).Value = ((TextBox)dvShippingInformation.FindControl("tbContactEmail")).Text; sqlCmd.ExecuteNonQuery(); for testing purposes ive added the max text in each textbox area, so each textbox has 50 characters or so and i get an error message as follows, when executing the query: "System.Data.SqlClient.SqlException: String or binary data would be truncated.

There may/may not be an upper limit for the number of rows in a table, but is there any performance-related limit?
I'm designing a database that stores results that have been acquired from a number of devices. Each device provides a set of data measurements every 10 minutes. Therefore each year a device will produce 52000 sets of results. If I design a table to store a row for each set of measurements from a device (PK is based on the timestamp and the deviceID), and if there are 100 devices recording for 5 years, there will be 52000x100x5 rows. Would I get a performance increase by separating this data into one table per year? Perhaps the year could be appended to the table name to identify the particular tables.
A secondary issue is some devices can also be configured to produce a different set of measurements every 10 seconds. In this case there will be hundreds of millions of rows over a 5 year period. Therefore I am considering bulking the results into an array for a 10 minute period, and storing this array as a blob each 10 minutes. Is this going to be faster or slower than having hundreds of millions of rows?
I have a partitioned view sitting over several tables and I'm slowlyapproaching the 256 number. Can anybody confirm if there is such alimit for the maximum number of tables that a partitioned view canhold?If this is true, does anybody have any suggestions or ideas to workaround this max limit?TIA!
I thought I understand the notion in the Title until I ran the query below. This query inserts a 5000 byte value into two columns in the same record and sql (2008) doesn't complain.
I came across this statement from ASP.NET forum : "..There is a limit to the level for OUTER JOIN ANSI SQL limit is four after that you may get strange results. ..." . I did a little research but without getting clear answer from the SQL92 standard itself. I am wondering whether I can get help about this in SQL Server 2005 implementation here.
I put this question in another way, How many tables can we use in OUTER JOIN(or INNER JOIN) in SQL Server 2005?
Is there a limit of how many rows a table can have in SQL compact Edition? I didn't find anything in the documentation, but I get regularly a funny error message "Expression evaluation caused an overflow. [ Name of function (if known) = ]" when I try to create record number 32768 (is equal to 2 to the power of 15).
Is there a performance limit on the number of indexes per table / database ? With Filtered indexes there appear to be many more opportunities for more finely defined, and therefore smaller indexes resulting in many more indexes on a single table.
I have a simple SP that returns 2 columns with 4 inner joins, results are about 100 odd rows max, nothing complicated. When I run the SP via SSMS it works fine, as soon as this is run via an application server the SP fails to complete with the error :
Internal error: An expression services limit has been reached. Please look for potentially complex expressions in your query, and try to simplify them.
We are not getting anywhere near the expression limit so I cannot understand why we are suddenly receiving this error. 2 weeks ago this query was running fine, no updates have been rolled out to the SQL database servers or application servers but the error is suddenly appearing on both prod and dev environments.
Hello everyone, I'm having an issue with dynamically setting the Send Mail task's to field to decent sized recipient list(approx 15 email addys). The strange thing is that this same package works fine if I'm using a list of say 4 email addys. I have double checked everything I can think of....list is seperated by semicolons, each address looks good....and have ran script tasks to check my variables along the path of the package but so far have not found the reason. The error I get is below:
"The specified string is not in the form required for an e-mail address"
Also of note, these addresses are being populated from a table, that is then setting the To string of the send mail task via a seperate variable...that variable being populated from a foreach loop. Again, all of this works fine with a smaller recipient list. Any ideas?
The only thing I can think of right now is to run the send mail task within the foreach loop...but then I'll be sending a seperate email for each address and would like to avoid that if possible.
I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.
The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.
Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.
Hi, I have application in which i am performing synchronization between SQL Server 2000 and SQL Server 2005 CE. I have one table "ItemMaster" in my database.There is no relationship with this table,it is standalone.I am updating its values from Windows Mobile Device.
I am performing below operations for that. Step : 1 Pull To Mobile
Code BlockmoSqlCeRemoteDataAccess.Pull("ItemMaster", "SELECT * FROM ItemMaster", lsConnectString,RdaTrackOption.TrackingOn);
Step : 2 Using one device form i am updating table "ItemMaster" table's values.
So i am getting an error on 3rd step. While i am trying to push it says, "The Push method returned one or more error rows. See the specified error table. [ Error table name = ]". I have tried it in different ways but still i am getting this error.
Note : Synchronization is working fine.There is not issue with my IIS,SQL CE & SQL Server 2k.
Can any one help me?I am trying for that since last 3 days.
I have SQL Server Management Studio Express (SSMS Express) and SQL Server 2005 Express (SS Express) installed in my Windows XP Pro PC that is on Microsoft Windows NT 4 LAN System. My Computer Administrator grants me the Administror Privilege to use my PC. I tried to use SQLQuery.sql (see the code below) to create a table "LabResults" and insert 20 data (values) into the table. I got Error Messages 102 and 156 when I did "Parse" or "Execute". This is my first time to apply the data type 'decimal' and the "VALUES" into the table. I do not know what is wrong with the 'decimal' and how to add the "VALUES": (1) Do I put the precision and scale of the decimal wrong? (2) Do I have to use "GO" after each "VALUES"? Please help and advise.
Thanks in advance,
Scott Chang

But now I am getting error "General Network Error. Check your network documentation" after specifying Use existing stored procedure in TableAdpater Configuration Wizard.
ALTER PROCEDURE dbo.Insert_MailSignature( @Singnature image )
AS
SET NOCOUNT OFF;
INSERT INTO MailsSignature (Singnature) VALUES (@Singnature);

For testing I created a desktop application and found that the same Code, same(Use existing stored procedure in TableAdpater Configuration Wizard) and same stored procedure is working fine in inserting image into the table.
ALTER TABLE [dbo].[CalCalendar] ALTER COLUMN [OID] uniqueidentifier NOT NULL PRIMARY KEY NONCLUSTERED
is answered with:
Server: Msg 156, Level 15, State 1, Line 2 Incorrect syntax near the keyword 'PRIMARY'.
which I consider to be interesting. Anyone has an idea why? I checked documentation but I do not see an error.
Note that:
ALTER TABLE [dbo].[CalCalendar] ALTER COLUMN [OID] uniqueidentifier NOT NULL
DOES get executed, and
ALTER TABLE [dbo].[CalCalendar] ALTER COLUMN [OID] uniqueidentifier NOT NULL PRIMARY KEY
produces the same error.
Now, in my understanding this has nothing to do with an index may already exist etc. - the eror indicates a SYNTAX error, before any checking. Makes no sense to me, though, reading the documentation.

When creating a database, SQL Server 6.5 seems to have a 2 gig limit. What I mean is that if the device chosen is over 2 gigs SQL Server displays the size of the device as anegative number. This prevents me from being able to expand the database when I need to. Can anyone tell me why this is so, and if there`s anyway around it??
we all know mysql: select * from table limit ?1, ?2

hi,I have a question.Maybe You know the equivalent to command LIMIT from MySQLI couldn`t find something like this in MS SQLPSI try to display 10 records begining form e.g. 4 sort by idsomething like: "SELECT * FROM table WHERE name=... LIMIT 4, 10 ORDER BY id"in MySQLthanx,Urban
I recently read up and found an msdn forum post that said the 4gb limit only applied to data files not log files.
However recently i had an error on a sql express database saying that the log file was full, the database log file was set to auto grow and there was plenty of space left.
So i am guessing the 4gb limit applies to any database file mdf or ldf, is this correct ?
I'm trying to send a Test Email to Operators defined in a SQL 7.0 server (currently on SP2). And get the following error message: "Error 22022: SQLServerAgent Error: MAPI error: Table too big."
We've checked the email profiles (also performed test on SQL MAIL) and can stop/start SQL Mail successfully. Verified that the accounts are correctly identified with appropriate permissions. MSDB is 150MB with no table that looks abnormal in size.
Has anyone come across this situation? Please let me know. THANKS!!!
I have the fields in my table: ID, Title, Description, Price, ImageData, Active I only want it to be possible to have two records at any time with Active=Yes. Active is a Bit, Yes/No, field. Any help is appreciated. Chuck
hi,i have a union statement that works like a charm:SELECT [Name], [EventID] AS [ItemID], [TourID], [Date], NULL AS [StartDate], [Date] AS [SortDate], [Type] FROM [Events] WHERE [TourID] IS NULL AND AccessLevel <= @AuthenticationLevel
UNION
SELECT [Name], [TourID] AS [ItemID], [TourID], NULL AS [Date], [StartDate], [StartDate] AS [SortDate], '2' AS [Type] FROM [Tours] WHERE AccessLevel <= @AuthenticationLevel
ORDER BY [SortDate] this statement selects all the records i want from both tables, and orders the entire new table by sort date.what i want to do is to add a limitation on the number of records. i have tried using both LIMIT and TOP commands, but i can't get it working. both of the below statements give me a syntax error saying "Incorrect syntax near the keyword 'ORDER'"first try:SELECT * FROM (<same_statement_as_above>) ORDER BY [SortDate] LIMIT 2second try:SELECT TOP 2 * FROM (<same_statement_as_above>) ORDER BY [SortDate]what am i doing wrong, and how do i achieve what i want?i am working with mssql server 2005 (express locally, and standard on my hosting service). thanks for your help!
I have an application with a DAL that has an interface with SQL Server. The application has 400 users that open the web forms. My question is: Is there a limit of the parallel connections that can be opened? Or the IIS is managing all the access to the DB? Should I worry about the performance Or it's normal behaviour for ASP.NET applications?
SQL takes all CPU resource on some of the intensive queries. Is any way to make sure there is something left for other tasks to be processed? Let's say limit SQL to use no more than 80% of CPU.
