Total Length Of Data Type In A Table
Oct 3, 2007
Folks:
I would like to know the total length of data type in a table. I ran the following query. Will this give me the correct information? I also ran sp_columns <table name> and it too give the length. But There is a difference in the numbers. Am I doing something wrong and which is the correct the query or sp_column.
select sum(length) from syscolumns
where id in (select id from sysobjects
where name = 'XYZABC')
sp_columns XYZABC
Thanks !

i have one col in a nonclusted index which is bigint 8 bytes follwoing result shows min_record_size_in_bytes and max_record_size_in_bytes is 20 that is 12+8 page size is 8 kB. does that mean a record will use 20 bytes in a page or it will only use the space equalent to data stored in the col.what i have seen is page count is same weather i put some data in the col or null

Hello folks!
I have written a stored proc that selects data from this table:
A1 AA
A2 BB
B1 AAA
B2 BBB
and puts it another table in this manner:
A1 AA BB
A2 AA BB
B1 AAA BBB
B2 AAA BBB
In short, I wanted to concatenate data in the second column.
My question is for some reason, SQL Server is limiting the length of the string to only 256 characters, even though I have defined the local variables in the storeds proc as varchar(1000) and the table has that field defined as text.
Any ideas how I can get around this problem?
Thanks!

For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,
LOSTlover

I am attempting to create a stored procedure that will launch at report runtime to summarize data in a table into a table that will reflect period data using an array type field. I know how to execute one line but I am not sure how to run the script so that it not only summarizes the data below but also creates and drops the table.
Any help would be greatly appreciated.

I'm moving data between identical tables and have to use a flat file as an intermediary. I thought: "No problem, SSIS can do a quick export to a file, then move the file to another server, then use SSIS to import the data to the new server."
Seems simple, right?
I'm hitting all sorts of surprising data conversion errors. I used the export wizard to create the export package. This works fine. However using the same flat file definition, the import package fails -- even when I have no destination. That is I have just one data flow task that contains only one control: the Flat File source. When I run the package the flat file definition fails with data type conversion and truncation errors. One of the obvious errors is for boolean types. The SQL field is a bit, SSIS defined the column as DT_BOOL, the output of the data are literal text values "TRUE" and "FALSE". So SSIS converts a sql datatype of bit to "TRUE" and "FALSE" on export, but can't make the reverse conversion on import?
Does anyone else find this surprising? I would expect that what SSIS exports, it can import given all the same table and flat file definitions. Is SSIS the wrong tool to do such simple bulk copies? I'd like to avoid using BCP because this process will need to run automatically within SQL Agent so we can leverage all the error tracking and system monitoring.

I am working on a program in VB 2005 in which i want to store and retrieve GPS coordinates. I am not sure which data type is the best to use to enter Latitude & Longitude numbers and maintain their proper integrity.
Like LAT ( N38 28.025' ) and LONG (W105 52.098' )
The numbers will be entered by the user and that format can be maintained, but how to re-enter & or insert them into the database using the same format is my real question.
I hope I have explained this right. The numbers in BOLD are what I need to maintain.
Thanks for any help in advance.

Hi all,I have a table called PTRANS with few columns (see create script below).I have created a view on top that this table VwTransaction (See below)I can now run this query without a problem:select * from dbo.VwTransactionwhereAssetNumber = '101001' andTransactionDate <= '7/1/2003'But when I create an index on the PTRANS table using the command below:CREATE INDEX IDX_PTRANS_CHL# ON PTRANS(CHL#)The same query that ran fine before, fails with the error:Server: Msg 242, Level 16, State 3, Line 1The conversion of a char data type to a datetime data type resulted inan out-of-range datetime value.I can run the same query by commeting out the AssetNumber clause and itworks fine. I can also run the query commenting out the TransactionDatecolumn and it works fine. But when I have both the conditions in theWHERE clause, it gives me this error.

After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.
anyone having this problem before?? hopefully you guys can help.

Hi,
I have a stored procedure which uses:
DECLARE @Tmp TABLE ( Row_ID INT IDENTITY(1,1), Property_ID INT)
And I'd like to reuse the table in the stored procedure and have attempted to empty the table by calling
TRUNCATE TABLE @Tmp
But this doesn't work. How else can I do this? I don't want to use
DELETE FROM @Tmp
Because this doesn't reset the Row_ID, and I'm using the Row_ID in a WHILE loop. Any ideas?

I am trying to add indexes to my table data types and have realized that I can only add primary keys. So, I am hoping there is a way to add a composite primary key, but I am not having any success. I have tried the following:
Declare @Sales TABLE
(SaleID INT IDENTITY(100000,1),
SalesRegion CHAR(2),
CONSTRAINT ID_PK PRIMARY KEY (SaleID,SalesRegion))
Any suggestions would be appreciated.

I would like to set a field to not null which I can do like this: ALTER TABLE table1 ALTER COLUMN field1 BIGINT NOT NULL
My question is there anyway to set this field to NOT NULL without having to specify the data type BIGINT? I'm using dynamic sql and if there was a way then I wouldn't need to go get the data type of the field dynamically and it would save me a step. Thanks.

Hi,
I have some stored procedures that create table data types for temporary tables. From everything I've read about these, they shouldn't occupy space in tempdb. However we've been having problems with our tempdb log growing quite large, so I've done some profiling on the database and found that the temporary tables are being created in tempdb, and I don't understand why.
The Stored Procedure looks like:
-- WORKING TABLES
DECLARE @t_InsertParams TABLE (ParamKey1 VARCHAR(50) NOT NULL, ParamValue VARCHAR(1024), ParamOrder INT)
/*** POPULATE PARAMS TABLES ***/
INSERT @t_InsertParams
SELECT *
FROM dbo.GetParamsOffload(@p_ParamList, @p_TargetTable)
and GetParamsOffload is a user defined function that returns a table:
CREATE FUNCTION GetParamsOffload(@p_ParamsList AS VARCHAR(8000), @p_TargetTable AS VARCHAR(50))
RETURNS @t_Params TABLE (ParamKey1 VARCHAR(50) NOT NULL, ParamValue VARCHAR(1024), ParamOrder INT)
AS
<snip>
INSERT @t_Params
SELECT @_ParamKey
,@_ParamValue
,ISNULL(@_ParamOrder, 0)
<snip>
RETURN
During the profiling of the application, I see numerous records of EventType "Object:Created" for the tempdb DatabaseId and the ObjectName is both @t_InsertParams and @t_Params. I am also monitoring the "Objecteleted" EventType, but I never see these objects deleted.
My first question is why this code uses the tempdb in the first place. I've read that you can't use the table data type in a few instances (can't insert the values of a SP execute into the table data type; cannot do SELECT INTO or INSERT INTO statements). Is there an issue with inserting data into the table data type from a function? Is there something that can be changed in the way the table data type is defined/used that will not use tempdb?
If I am stuck with the above using tempdb, is there something that should be explicitly called to Delete the specified objects from tempdb? Do I need to Drop those tables in my SP?
This SP is called via a CSV file parser - gets called A LOT over and over parsing files and I see these objects getting created in tempdb. I need to figure out how this process can manage the space in tempdb better.
I'm using SQL Server 2000.
Thanks for any help.

Hi,
I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:
this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);
this.mycourtsDataSet1.AcceptChanges();
this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);
This did not happen with VS2005/CE3.01.
I have tried changing all references to decimal (or money in CE3.5) without luck.
I'm beginning to think that string may be the way to go!!!!!!!
Can someone shed some light on my problem.
Thanks,
Later:
It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.

We have some columns in a table where the date is stored as 19980101 (YYYYMMDD). The data type for this column is NUMBER(8) in Oracle.
I need to copy rows from Oracle to SQL Server using SSIS. I used the Data Conversion transformation editor to change it to DT_DATE, but the rows are not being inserted to the destination.
On Error, If I fail the component, then the error is :
There was an error with input column "ORDER_DATE_CONV" (1191) on input "OLE DB Destination Input" (29). The column status returned was: "Conversion failed because the data value overflowed the specified type.".

Hi,
I've a column col1 of image data type in table1. I would like to copy the data from col1 to another image column col2 in table2. Before moving the value, checking has to be done to specify which col1 data from table1 is needed and the destination has to be checked too.
Example: insert into col2
(select col1 from table1 where table1_id =5)
where table2_id =6
Hence bcp wouldn't work. Can anyone suggest me a way to do it. I tried using writetext but then, i've to get data from col1 in a variable, which is not possible. Any suggestions would be very helpful.
Thanks in advance.

However, I have problem with one field which data type is text.
MS SQL always return me this error:
Cannot use text, ntext, or image columns in the 'inserted' and 'deleted' tables.
I use the following code to take the data from deleted table
DECLARE @ptrval varbinary(16)
SELECT @ptrval = TEXTPTR(NOTES )
FROM DELETED
I also tried simple Select statement
Select notes from deleted
What code should I use to take the deleted data
Please help.
