There are two tables, parent and child table.
Foreign key field of the child table is not a required field. If the
data is submitted w/o a value into the foreign key field, what should
I make it as a default value? Should it be "null"?
I have table "Clients" who have associated records in table "Mailings"
I want to populate a gridview using a single query that grabs all the info I need so that I may utilize the gridview's built in sorting.
I'm trying to return records containing the next upcoming mailing for each client.
The closest I can get is below:
I'm using GROUP BY because it allows me to return a single record for each client and the MIN part allows me to return the associated record in the mailings table for each client that contains the next upcoming 'send_date'
SELECT MIN(dbo.tbl_clients.client_last_name) AS exp_last_name, MIN(dbo.tbl_mailings.send_date) AS exp_send_date, MIN(dbo.tbl_mailings.user_id) AS exp_user_id, dbo.tbl_clients.client_id, MIN(dbo.tbl_mailings.mailing_id) AS exp_mailing_idFROM dbo.tbl_clients INNER JOIN
dbo.tbl_mailings ON dbo.tbl_clients.client_id = dbo.tbl_mailings.client_idWHERE (dbo.tbl_mailings.user_id = 1000)GROUP BY dbo.tbl_clients.client_id
The user_id set at 1000 part is what makes it rightly pull in all clients for a particular user. Problem is, by using the GROUP BY statement I'm just getting the lowest 'mailing_id' number and NOT the actual entry associated with mailing item I want to return. Same goes for the last_name field. Perhaps I need to have a subquery within my WHERE clause?Or am I barking up the wrong tree entirely..
Newbie question. Can someone show me an SQL statement that sorts the results of a query by a field in a different table?
CREATE TABLE `Table1`
(
`table1_id` INTEGER AUTO_INCREMENT ,
`table1_name` VARCHAR(255),
PRIMARY KEY (`table1_id`)
)
CREATE TABLE `Table2`
(
`table2_id` INTEGER AUTO_INCREMENT ,
`table2_name` VARCHAR(255),
`table2_table1` INTEGER,
PRIMARY KEY (`table2_id`)
)
ALTER TABLE `Table2` ADD FOREIGN KEY (`table2_table1`) REFERENCES `Table1`(`table1_id`);
What I'd like is something like:
SELECT * FROM Table2 ORDER BY "Table1(table2_table1).tabel1_name",table2_name
It's the section in double quotes that I can't figure out how to compose.
As an example, if Table 1 has
1, A
2, B
3, C
and Table 2 has
1, a, 2
2, b, 1
3, c, 2
then I'd like the sort to return
2, b, 1
1, a, 2
3, c, 2
TIA,

How can i find the primary field name and primary table name of a given foreign key.
For example
Table A:
IDa
Column1
Column2
Column3
Table B:
IDb
column1
column2
column3 <---- this is foreign key to table A's IDa
What i want to do is i pass input of tableB, column3 and i get name of Primary tableA and field name IDa. How is it possible to do in tsql ?
I am doing a shopping basket type demo.I have difficulties going from table with fields like (Name,ProductCode) to table(Name, ProductCode, NumberOfItems). One way could be adding just Name and ProductCode fields and let NumberOfItems come automatically. It could have some common value like 1. How should I do this with VB.

I have a field call: password, I want to generates some random chars as
default password for users (so user got something to login, and update
later).
Current Solution I have:
I made myself a trigger and it does generate password on insert, but
the problem with that is I have to allow NULL on that field. I
don't want NULL to be allowed, and if I don't allow null... sql server
won't allow me to insert a record (when leaving password field empty).
Reason i don't wanna allow NULL on that field, is because there may be
more applicaions using the same field from the same database.
Just in case if the other developer gets sloopy, I don't want other
application(s) allow user put to enter a null or leave it blank on my
password field.
My question is:
1) can I put a function or some sort at the "Default" field under "Design Table", if so...how?
2) any suggestions for a better implementation?
3) if (1) doesn't work, what other options would you suggest other then the current trigger i'm using?
TIA
I have a datatable : Data_Table and a look up table: Lk_table. Myfield that I
use in Inner Join is defined in both the
data and look table.
So I build my query like this:
SELECT * FROM dbo. Data_Table INNER JOIN
dbo. Lk_table ON dbo.Data_Table.MyField = dbo.Lk_table.Myfield
The pb, sometimes I
have myfield still with its default null value in the datatable: Data_Table.
So, I end up getting 0 record when I execute the query shown above.
How do I turn that around so that even if myfield in Data_Table
is Null, I still get the records from Data_Table. (I don t want a set of
records including all possible values from the look up table: Lk_Table)
I have a situation that I must resolve. I have a program being used by many but I had to create a new table to provide a new feature. The problem I have is this table must use the primary key from the parent table as its primary key, meaning when a user adds a new record to parent table, I need to instantly add the primary key to the child table. Now this was done in the program using sql statements, but I need to implement a trigger or such as to keep me from having to reinstall application on many computers.
basically person inserts new record, then I need to get the new primary ket and add insert it into the child tables. how can I do this with a trigger. I have tried to use an insert into statment with my trigger, but I can't seem to pass the parameters correctly.

Hi All,
I need to create a new field on a table and have that field default to another field value in that same table. Is there a way to do this w/ a default constraint rather than adding a trigger to the table? If i can't use a default constraint does anyone have a template trigger i could use?

is there a way to cascade update to foreign keys where both fields (PK & FK) are located in two different database?
View 2 Replies View RelatedI'm a total newb to SQL so I apologize if I butcher the description of what I'm looking to do :) Hopefully the example makes more sense. Is it possible for a single record in 1 table to contain relationships to several records in a different table?
What I've got so far is 2 tables - Hardware and Software, with ID Specifying primary keys HardwareID and SoftwareID respectively. the hardware records are for computer details and the software obviously are for programs. What I need to be able to do is pull up a hardware record and be able to see what software is installed on it, and vice versa pull up a software record to see which computers it's installed on. The problem I'm running into is that a computer can have multiple programs installed on it and a program can be installed on multiple computers, so I don't know how to create that relationship to account for that.
What I'd like to see is in the Hardware table a column for SoftwareID that has a foreign key relationship to the SoftwareID field in the Software Table, and vice versa....My question though is is that possible to do and have potentially multiple separate records it links to from that same column field? I might have a computer with say Windows XP Pro, Office 2003 Standard, Adobe Acrobat 8 and a proprietary rate calculator program that i need each to be displayed with their details when I open that computer's record. Or on the software side if I need to see which computers a license is already installed on then I want to make sure I can pull up the full list of computers.
And finally if what I'd like to do isn't possible as I described it...any recommendations for a better way?
Thanks all for the help!
Hello,
I have two tables (one-to-many relation) related thru a common key. I have setup the Relation using the Database Designer. The Form is populated using Drag-and-drop which automatically adds the BindingSource, TableAdapter, and Binding Navigator. The Relation works great in the change mode, and life is good.
In the Add mode the field setup with the Foreign Key is not automatically populated as it is in Change mode. The field can be updated manually, but that defeats the purpose of setting up the Relation.
Any ideas how to fix this?
I know this is difficult to visualize without seeing it.
Thank you for any ideas,

Hi there
We have a SSIS run which runs as follows
The master package has a configuration file, specifying the connect strings
The master package passes these connect-strings to the child packages in a variable
Both master package and child packages have connection managers, setup to use localhost. This is done deliberately to be able to test the packages on individual development pc€™s.
We do not want to change anything inside the packages when deploying to test, and from test to production. All differences will be in the config files (which are pretty fixed, they very seldom change). That way we can be sure that we can deploy to production without any changes at all.
The package is run from the file system, through a job-schedule.
We experience the following when running on a not default sql-server instance (called dkms5253uedw)
Case 1:
The master package starts by executing three sql-scripts (drop foreign key€™s, truncate tables, create foreign key€™s). This works fine.
The master package then executes the first child package. We then in the sysdtslog get:
Error - €ścannot connect to database xxx€?
Info - €śpackage is preparing to get connection string from parent €¦€?
The child package then executes OK, does all it€™s work, and finish. Because there has been an error, the master package then stops with an error.
Case 2:
When we run exactly the same, but with the connection strings in the config file pointing to the default instance (dkms5253), the everything works fine.
Case 3:
When we run exactly the same, again against the dkms5253uedw instance, but now with the exact same databases defined in the default instance, it also works perfect.
Case 4:
When we then stop the sql-server on the default instance, the package faults again, this time with
Error - €śtimeout when connect to database xxx€?
Info - €śpackage is preparing to get connection string from parent €¦€?
And the continues as in the first case
From all this we conclude, that the child package tries to connect to the database before it knows the connection string it gets passed in the variable from the master package. It therefore tries to connect to the default instance, and this only works if the default instance is running and has the same databases defined. As far as we can see, the child package does no work against the default instance (no logging etc.).
We have tried delayed validation in the packages and in the connection managers, but with the same results (error).
So we are desperately hoping that someone can help us solve this problem.
Thanx,

View 3 Replies View RelatedI ran into an interesting situation. I'm working on contract and was looking at creating an ERD for an existing database when I ran into a problem. I found FK's that are referencing columns that do not have a unique constraint or a unique index.Â
I don't know the history of the database but was there a time in SQL Server history where this would have been possible? I scripted out the tables and created it in a test database. When I run the script to create the FK I get the following message.Â
I double checked the original tables and this FK does exist in table1 and there is no unique anything in the referenced table, table2. Currently the database is running on SQL Server 2008 Ent.
ALTER TABLE [dbo].[table1] WITH CHECK ADD CONSTRAINT [FK_table1] FOREIGN KEY([Col1])
REFERENCES [dbo].[table2] ([col2])
There are no primary or candidate keys in the referenced table 'dbo.table2' that match the referencing column list in the foreign key 'FK_table1'.
Is it possible to change the default value of a field using a stored proc or query? Any hints on how to do this if it is possible would be appreciated!

I'm copying MyDbTable to TempdbTable. There are 12 fields and I'm ignoring 11 of them when copying the one table to another with DTSWizard.
Once the TempdbTable is there, I'm adding 2 fields along with the one that is there already.
1) field1 int, Nullable, Default value ((3))
2) field2 tinyint, Nullable, Default value ((1))
The reason why I'm creating these two fields and giving them a value so they will match up when I import TempdbTable to MyDb2ndTable.
The problem I'm having is... field1 and field2 have a Null value intead of the value I'm giving them.
I'm new at this, so maybe the cause of the problem is obvious, but if anyone can help me I'd really appreciate it.

For number and character fields, the default is pretty obvious, but is there any empty value for a date field? I think a null there might be better than putting in a bogus date, at least it can be tested for.
Are there any more developend ideas on this question?

ALTER TABLE TableName alter column ColumnName int default 0

SO i thought about changing the default value to int (im thinking this means integer?) and changing it to '3' but it still displays the decimal point and two 0's
Am I doing something wrong here? I just want it to display '0'
Thanks
should I set to "0" as a default value on a quantity and a price fieldor set to "null"?if a user enter nothing on the quantity or price field on a webbrowser, should I treat it as null or "0"? I am so confused about thisconcept. please advise me. thank you.
