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.
Thanks!
hi, can I have a composit primary key which have more than one data type. for instance job_id int,job_type varchar(20)... thanks

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.

Hello,
I have a table which has a composite primary key consisting of four columns, one of them being a datetime called Day.
The nice thing afaik with this composite key is that it prevents duplicate entries in the table for any given day. But the problem is probably two-fold
1. multiple columns need to be used for joins and I think this might degrade performance?
2. in client applications such as asp.net these primary keys must be sent in the query string and the query string becomes long and a little bit unmanagable.
A possible solutions I'm thinking of is dropping the existing primary key and creating a new identity column and a composite unique index on the columns from the existing composite key.
I would like to have some tips, recommendations and alternatives for what I should do in this case.
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.
The table above is my users table. It allows for a user to be at multiple sites or multiple locations within a single site or multiple sites. Would it be wise to use a auto incrementing primary key instead of the 3 column composite key? The reason I ask is because if I am referencing this SU table (which I will be a lot), a lot more data would be replicated to the tables which have the foreign key to this table, right? But if I used a single incrementing column as the primary key, only a small integer would be used as the foreign key, saving space?Does this make sense?

well i want to have an web-based database application in which in an single webform , i need to insert the values to 5 different tables.
here empid is primary key (PK) in one table and in the rest of the tables its an Foreign Key(FK)
my question is, how can i create these tables with composite key?
ie, i want to creat an table which will have FK and as well another key which both will uniquely idenitfies a row.
Well i am using SQL server 2000 and i wish to create these tables using the enterprise manager.
here are the tables

empid,fname,lname
2)empcountrytable
empid,country
3)empvisatable
empid,visa
4)empdoctable

Plz do help me
thanx in advance
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.

I have three tables that are important here, a 'Plant' table a 'Spindle' table and a 'PlantSpindle' table. The 'PlantSpindle' is comprised of a PlantID and a SpindleID acting as the Primary Key for the table with no other fields.
I have an aspx page that captures the appropriate data to create an entry in the Spindle table. Depending on the user, I will know which plantID they are associated with via a querystring. In my storedproc I insert the data from the webform into the Spindle table but get stuck when I try to also insert the record into the PlantSpindle table with the PlantID I have retrieved via the querystring and the SpindleID of the spindle record the user just created. Basically, I am having trouble retrieving that SpindleID.
Here is what I have in my storedProc (truncated for brevity).
CREATE PROCEDURE [dbo].[InsertSpindle]
@plantID int,
@spindleID int,
@plantHWG varchar(50),
@spindleNumber varchar(50),
@spindleDateInstalled varchar(50),
@spindleDateRemoved varchar(50),
@spindleDurationMonths float(8),
@spindleBearingDesignNumber int,
@spindleArbor varchar(50),
@spindleFrontSealDesign varchar(50),
@spindleFrontBearing varchar(50),
@spindleRearBearing varchar(50),
@spindleRearSealDesign varchar(50),
@spindleNotes varchar(160)
AS
SET NOCOUNT ON
INSERT INTO Spindle
(plantHWG, spindleNumber, spindleDateInstalled, spindleDateRemoved, spindleDurationMonths,
spindleBearingDesignNumber, spindleArbor, spindleFrontSealDesign, spindleFrontBearing,
spindleRearBearing, spindleRearSealDesign, spindleNotes)
VALUES
(@plantHWG, @spindleNumber, @spindleDateInstalled, @spindleDateRemoved, @spindleDurationMonths,
@spindleBearingDesignNumber, @spindleArbor, @spindleFrontSealDesign, @spindleFrontBearing,
@spindleRearBearing, @spindleRearSealDesign, @spindleNotes)
SET @spindleID = (SELECT @@Identity
FROM Spindle)
INSERT INTO PlantSpindle
(plantID, SpindleID)
VALUES
(@plantID, @SpindleID)
I have guessed at a few different solutions but still come up with Procedure 'InsertSpindle' expects parameter '@spindleID', which was not supplied when I execute the procedure.
Any help would be appreciated! thanks!
NOTE:
I am not interested in any responses that want to argue the use of a unique ID field and autonumbering as the PK. It is quite clear from the forums that this subject is a polarizing one. This question is for those who follow text-book design practices and believe that a composite primary key should be used when it is available. I want to be one of them for the time being.
SYNOPSIS:
I have three tables, TestSummary, TestDetails, and Steps.
The TestSummary table looks like this:
Create table TestSummary
(
TestSummaryID int identity primary key,
...
SequenceID int not null
)
It contains the date and time of the test, the serial number, the part number, the test operator's name, and the ID of the sequence of steps used during the test. It uses a unique ID field for the primary key.
The TestDetails table looks like this:
Create table TestDetails
(
TestDetailsID int identity primary key,
TestSummaryID int not null,
StepID int not null,
...
)
It contains the details of the test like voltage readings, current readings, temperature, etc., one record per reading. It also contains the step number of the test sequence specified in the TestSummary table.
The Steps table looks like this:
Create table Steps
(
SequenceID int not null,
StepID int not null,
Function int not null
Primary key (SequenceID, StepID)
)
It contains a list of all of the functions to be performed on the device under test by sequence number and the step number within the sequence.
When I try to establish a relation between TestSummary.SequenceID and Steps.SequenceID, SQL Server flags an error because TestSummary.SequenceID and Steps.SequenceID:Steps.StepID do not match.
What is the problem with this approach?
Is is possible to create a composite primary key on a table variable?Neither of these two statements are successful:DECLARE @opmcjf TABLE (jobdetailid INT NOT NULL,cjfid INT NOT NULL,cjfvalue VARCHAR(100) NULL)ALTER TABLE @opmcjf ADD CONSTRAINT [PK_opmcjf] PRIMARY KEY CLUSTERED([jobdetailid],[cjfid])andDECLARE @opmcjf TABLE (jobdetailid INT PRIMARY KEY,cjfid INT PRIMARY KEY,cjfvalue VARCHAR(100) NULL)Thanks,Shaun

CREATE TABLE Table1 (

CREATE TABLE Table2 (
Email <------

How can I use Table1's Email column's data type as for Email col in Table2. I remember it's possible in Oracle
Thank you
Can anybody tell me why can't we write this...
declare @tab1 as table
Plz tell me if there are any use of table data type rather than UDFs..
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?
How can I use Table Data Type as parameter for Stored Procedures and Functions.

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 All
I want to retrieve the data type of table column and validate the input data whether same as data type of table column before insert into database. Any suggestion?
I use asp.net + msde
Thank you.
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.
Ramya.
Does any one have any examples of how to declare and use these properly?
MSDN doesn't seem to give any example for a beginner.
Can we retrieve data from table type variable as an array in oracle key values..
E.g.
ALTER PROCEDURE prn1( @p_prn as KeyValuePair readonly)
-- proc which having parameter table type as parameter
AS
declare @v_formatted_str varchar(50)
BEGIN
set @v_formatted_str = v_formatted_str + @p_prn(1)(1)
END
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.

select sum(length) from syscolumns
where id in (select id from sysobjects

I also tried simple Select statement
Select notes from deleted
What code should I use to take the deleted data

On sqlserver 2000 transactional replication:
How would I best go about changing a published table's column from smallint to int? I could not find anything about it in BOL or MS.com. I do not think EM/Replication Properties allows the change. I suspect I have to run "Alter Table/Column" on the Publisher and each Subscriber the old-fashioned way. Is that true?
Thanks!
