Is there a way to check the data type and the maximum length of a field?
I have some code I build 2 weeks ago which Iâve been running daily but itâs suddenly stopped working with the following error.
âThe table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limitâ When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit Iâm puzzled with is it was working and stopped.
I donât recall changing anything but I wouldnât rule that out. I âve inspected the source files and I donât believe they have changed either.
DECLARE Â Â Â Â Â Â Â Â Â Â Â Â Â
@FileName varchar(50),
@Path varchar(50),
@SqlCmd varchar(1000)
= '',
@ASXCode varchar(5),
@Offset decimal(18,0),
[code]....
I am using MS SQL server 2008, and i have a table with 350 columns and when i m trying to create one more column its giving error with below message -
Warning: The table XXX has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes.
INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
how can i resolve this?
I posted this in another area and didn't get an answer, so maybe I posted it in the wrong place. Forgive me if you've seen this twice.
I'm trying to figure out what the ultimate size limitation for a SQL 2005 Enterprise server is. This document is helpful but I'm a bit confused:
http://msdn2.microsoft.com/en-us/library/ms143432.aspx
In the document, it says that the maximum database size is 524,258 terabytes; however, it also says that the maximum data file size--which I assume is the .MDF file--is 16 terabytes. My question is, how can you create a 524,258 TB database if the maximum file size 16 TB?
Dumb question, I'm sure...please enlighten me!

How much data we can pass through as an XML Text into SP by the concept OPENXML
Is there any limit to the maximum size of a datafile or transaction log you can have with SQL Server 2000 on Windows 2000. Also is there a maximum size that should be adhered to for performance and admin reasons ?.

Hi, All,
if I set the "Maximum insert commit size" to 10 ( 0 is the default) in a OLE destination,
what does the 10 means? 10 records or 10 MB/KB of data?
Thanks
Hi,
I've found a two different answers for this question:
one - on the http://support.microsoft.com/Default.aspx?kbid=920700 site where on the Performance improvements section there is a 128MB value in the Database size.
other is in the product datasheet there is a information that this version supports databases up to 4 GB.
Could you tell me what is the correct answer?

Hi,
I'd like to replicate an SQL Server Database to an SDF file. For Simplicity I want to use the SQL Server 2005 Management Console. The Console reports that the maximum buffer size were to small. In the comment (c# code) I can see it is set to 512. How can I increase the value in the replication assistant?

In SSIS, what is the maximum size of the String variable (one that you would define in the Variables dialog box)?
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,

P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
One of our production databases was setup mirroring, log shipping and replication on it, the log file was setup unrestricted growth. This morning one index rebuilding process generated lots of logs, and the log file disk ran out of space, the database was in recovery mode. so we had to disable log shipping, pause mirroring and replication, expand log file disk, restarted SQL instance to fix the issue. Now we want to setup the log file to maximum size 80G, the whole log file disk is 120G.
So if the log file reached 80G next time, we can change the max size to 90G or 100G and it's easier to fix the space issue. My question is, if the database  log file reached max size,
1. is the database still available?Â
2. Will the active session causing the issue be rollback to release space back?
I'm seeing some strange behavior from the OLE DB Destination when using the "fast load" access mode and setting the "Maximum insert commit size".
When I do not set the "Rows per batch" or the "Maximum insert commit size", the package I'm working with inserts 123,070 rows using a single "insert bulk" statement. The data seems to flow through the pipeline until it gets to the OLE DB Destination and then I see a short pause. I'm assuming the pause is from the "insert bulk" statement handling all of the rows at once.
When I set the "Rows per batch" option but leave the "Maximum insert commit size" alone, I generally see the same behavior -- a single "insert bulk" statement that handles all 123,070. In this case, however, the "insert bulk" statement has a "ROWS_PER_BATCH" option appended to the statement that matches the "Rows per batch" setting. This makes sense. I'm assuming the "insert bulk" then "batches" the rows into multiple insert statements (although I'm unsure of how to confirm this). This version of the "insert bulk" statement appears to run in about the same time as the case above.
When I set the "Maximum insert commit size" option and leave the "Rows per batch" statement alone, I see multiple "insert bulk" statements being executed, each handling the lower of either the value I specify for the "Maximum insert commit size" or the number of rows in a single buffer flowing through the pipeline. In my testing, the number of rows in a buffer was 9,681. So, if I set the "Maximum insert commit size" to 5,000, I see two "insert bulk" statements for each buffer that flows into the OLE DB Destination (one handling 5,000 rows and one handling 4,681 rows). If I set the "Maximum insert commit size" to 10,000, I see a single "insert bulk" statement for each buffer that flows into the OLE DB Destination (handling 9,681 rows).
Now the problem. When I set the "Maximum insert commit size" as described in the last case above, I see LONG pauses between buffers being handled by the OLE DB Destination. For example, I might see one buffer of data flow through (and be handled by one or more "insert bulk" statements based on the "Maximum insert commit size" setting), then see a 2-3 minute pause before the next buffer of data is handled (with its one or more "insert bulk" statements being executed). Then I might see a 4-5 minute pause before the next buffer of data is handled. The pause between the buffers being passed through the OLE DB Destination (and handled via the "insert bulk" statements) is sometimes shorter, sometimes longer.
Using Profiler, I don't see any other activity going on within the database or within SQL Server itself that would explain the pauses between the buffers being handled by the OLE DB Destination and the resulting "insert bulk" statements...
Can anyone explain what is going on here? Is setting the "Maximum insert commit size" a bad idea? What are the differences between it and the "Rows per batch" setting and what are the recommended uses of these two options to try to improve the performance of the insert (particularly when handling millions of rows)?
TIA for any thoughts or information...

I am running a script which has a table creation. The table gets created, but with the below warning.
Warning: The table 'PropertyInstancesAudits' has been created but its maximum row size (8190) exceeds the maximum number of bytes per row (8060). INSERT or UPDATE of a row in this table will fail if the resulting row length exceeds 8060 bytes.

How should I get rid of this?
This has me stumped.
I have a table UnitRateItems with the following columns
ItemID, Description
and table UnitRates with the following columns
ItemID,Year,UnitRate
UnitRateItems and UnitRates have a primary-foreign key relationship on ItemID.
In UnitRates, there may be several rows with the same value for ItemID but a different value for Year. What I want to do is pick the row with the largest value of Year for a given ItemID. I want to do this for ALL the rows in the table (not just for a particular ItemID).
In other words, I want to return one row in UnitRates for each row in UnitRateItems. I want that one row to be the one with the highest Year for that ItemID.
It sounds simple, but I can't seem to figure out how to do it. The MAX function only works on a single column. I can get the MAX Year, but then I can't tell it "pick up the other values that go with the row with the MAX Year".
Any help would be greatly appreciated!

using an OLE DB Source and a SQL Server Destination, I get DT_DBDATE to DT_DBTIMESTAMP
errors on two fields from Informix which are date data ....no timestamp part
I tried a couple of things:
Created a view of the Informix table where I cast the date fields as datetime year to fraction(5), which failed.
Altered the view to convert the date fields to char(10) with the hopes that SQL Server would implicitly cast them
as datetime but it failed.
What options do I have that will work?

I have a problem selecting maximum values inside a data flow, when the field is varchar. For example, I could have an incoming text file with following rows (the real life problem is a bit more complicated, but the idea is the same)
ID Desc
1 Car
1 Truck
1 Bicycle
2 Horse
2 Cow
Now I would like to group by ID, and have the maximum value from the Desc field, resulting
ID Desc
1 Truck
2 Horse
I tried to sort the data flow first with ID ascending and Desc descending, followed by sort with ID ascending and "Remove duplicate sort values" turned on. However, the sort does not seem to select the first Desc value it gets, because the result is.
ID Desc
1 Bicycle
2 Horse

Hello,
I am working on an accounting system using VB.NET and sql server 2005 as a database. the application should be used by multiple users.
i have a the following structure:
Voucher: ID (primary), Date,TypeID, ReferenceCode, .....
Type: ID, Code, Name. (the user can add new type anytime!)
(Ex: PV- payment voucher, JV - Journal Voucher ,....)
When adding a voucher the user will choose a type, according to this type (for each year) a counter will be increminted.
for example: PV1, PV2....PV233,... the other type will have its separate counter JV1, JV2 ,...JV4569,..
I am using the sqlTransaction cause i am doing other operations that should be transactional with the insertion of the Voucher.
The question is :
What is the best solution to generate a counter for each type?(With code sample)
Thanks.
