DECLARE @datetimeoffset datetimeoffset(3)
DECLARE @datetime datetime
SELECT @datetimeoffset = '2012-11-08T17:22:13.575+00:00'
SELECT @datetime = @datetimeoffset
SELECT @datetimeoffset AS '@datetimeoffset ', @datetime AS 'datetime'
__________________________________________________ ___________
Result of above SQL is
@datetimeoffset datetime
2012-11-08 17:22:13.575 +00:002012-11-08 17:22:13.577
__________________________________________________ ____________
The result should be '2012-11-08 17:22:13.575', why the milliseconds value is incorrect
We made a poor decision a long time ago when designing our databasestructure. We used bigint data types as the identity keys for many ofour base tables. For many reasons I would like to change these fieldsto int at the largest. The largest data in these fields is around200,000. I know that int can easily store this.What should I be worried about when changing these fields from bigintto int? If anything. Your help is appreciated. I did severalsearches without much luck.
View 5 Replies View RelatedHi there, I have a table that has an IDENTITY column and it is the PK of this table. By default SQL Server creates a unique clustered index on the PK, but this isn't what I wanted. I want to make a regular unique index on the column so I can make a clustered index on a different column.
If I try to uncheck the Clustered index option in EM I get a dialog that says "Cannot convert a clustered index to a nonclustered index using the DROP_EXISTING option.". If I simply try to delete the index I get the following "An explicit DROP INDEX is not allowed on index 'index name'. It is being used for PRIMARY KEY constraint enforcement.
So do I have to drop the PK constraint now? How does that affect all the tables that have FK relationships to this table?
Thanks
I have a table named PERSON and a field named PERSON_ID. How can I set this field to Autonumber? I know I have to use the IDENTITY command, but when I view this field in "design" view, all the IDENTITY options are grayed out.
How can I set this field with the IDENTITY properties?
Thanks
hi all,
i have an autonumber field (primary key) and another integer field as part of a table. What i want to do is when a record is created, the default value of the integer field should be the_autonumber+1000 for eg record with pk 82 will have an integer field that's automatically 1082. Would it be possible to do this ? Thanks in advance.
If I have a field where 99.9% of the time the answer is going to be "No", would I be better, in terms of disk space, using:
A bit field
OR
A tiny int field, with a NULL for the 99.9% that are "NO", and a 1 for those that are "YES".
I'm using SQL Server 7.0.
My application developer has no preference.
Thanks.

I have a field ID of type integer, I want to put two numbers in that field: 3 and 7, so what I do is just store the number 37.Now, is there a command in SQL server which checks if the ID field contains a number I look for, say 7.Something like a CONTAINS keyword...If there is, could someone please tell me what it is AND tell me a bit more about it :memory usage, (dis)advantages etc.

Hello,
I am trying to write an SQL command to set the default value of an integer column I have within a table.
ALTER TABLE TableName alter column ColumnName int default 0
Any suggetions?
We have account numbers that are string values, looking like: "01.02.02.00.0040.000.000".
We need to parse individual segments and pull out a range of values treating the segment like an integer. For example we would like all accounts that have the fifth segment ranging in values from .0040. through .0060. inclusive.
We've been trying to do something with the like clause: LIKE '__.__.__.__.[0-0][0-0][4-6][0-0]'.
We want 40 through 60 but we're getting 40, 50, and 60. If we change the last bracket to [0-9] we get 40 through 69.
Does anyone have any suggestions as to either fix our like clause or another approach?
Thanks.

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,

Hello,
what's best for year resp. quarter Field, char(4) resp. char(1), integer or other?
Both are part of a composite index.
Thanks

I am facing problem with re numbering of field records in a table.I am having one table with below records.
sid(identity/primarykey) stickyId(Integer) UserId(integer)
102 0 171
103 1 171
104 2 171
105 3 171
here how to renumbering stickyId values when deleted particular stickyId from UI. Here stickyId field is Integer type only. not primarykey/identity field.
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,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?

Currently I have the following stored procedure which simply adds a new row in my SQL Express 2005. What I want is that -1). before inserting the record find out the new ID (primary key) value.

Thanks ALTER PROCEDURE usp_tbl_Company_Insert @Company_ID int, @Name varchar(200), AS<FIND THE NEW ID of the new row in the database> @Company_ID = (new ID) INSERT INTO tbl_Company (Company_ID, Name,)VALUES (@Company_ID, @Name)

I did create the field on table as TinyInt. I created an appending query and appended the records to the SQL table. Now I have 0's or 255's in the field.
Shouldn't they be 0's and 1's instead????
What am I doing wrong?

I have been asked to investigate the feasibility of converting an Invoice Number field from 6 to 7 digits, and allowing alpha characters. This means CHAR. The Invoice Number is not used outside of the application, but changes would have to be made to the database, and VB code that runs the app. Any ideas on how to proceed?
Any responses would be greatly appreciated!

I created a small SQL Express database/ASP.net/C# application and in the learning process. Before I implement it I would like to re-set autonumber / identity field back to 1. Also, I need to start with the blank database. I am not sure how to approach that?
Can you assist?

Please, How can I get the value of the identity field of the register that I was including in the data base. I am using a stored procedure in SQLSERVER in a asp .net application and I need to show that for the user, it´s like the number of the reclamation.
View 2 Replies View RelatedIf my table has an IDENTITY field, say, the table schema is:
CREATE TABLE BBB(
id int NOT NULL IDENTITY(1,1),
name varchar(20),
job varchar(40))
My data file, which does not carry the IDENTITY field
and its field terminator. The data file looks like this:
debbie cao,programmer
John Doe,engineer
Mary Smith,consultant
I tried to use a format file to bulk copy data from the
data file to the table. Never had any luck.
On the other hand, if I put a comma before the name field,
say, the data file looks like the following:
,debbie cao,programmer
,John Doe,engineer

then, bcp works fine.
But, my data file is automatically generated. It does not
suppose to have the leading comma. Without the leading comma,
I have no idea how may I make bcp work. The SQLBOL says it
can be done. Does anybody have an example to show me?
Please help, thanks!
Dear Fellow Administrators,
We are experiencing an identity problem on a table with 3.7 millions rows of data in the table. The identity field is not auto numbering any more and are wondering if anyone has a suggestion on how to get the auto number field working again without doing a bcp and restoring the table back to the database from bcp. Any suggestions?
Thanks in Advance,

Greetings !
Having an unusual problem - have created several (20) tables in a database.
All of these tables have an identity field in them (defined as FIELDNAME int IDENTITY(1,1) NOT NULL ). In most of the tables this works as expected, but in 2, so far, when I do the first load (an insert based on a different database) the identity fields are all zero.
Have recreated the tables, changed the field name and location, etc.
Anyone have any clues ?
TIA
Eric

Folks
I am inserting some values into a table with the following stmt
Insert into table(number,name) values ('12','name')
In the table I have one more identity column ID. I know that I cannot insert a value in that column and the value is automatically increased once I insert a record. After this insert statment, I need to get the value
of the ID (the most recent one) in the next select statement.
ie Select @@identity from table (any condition????)
How do I get the most recent ID value? Actually I m inserting the records in a loop and the ID is increased for every insert.
Thanks for the help,
