How To Make Or Add A Table With A Field With Default Value
Nov 7, 2007
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.
Hiim new to ms sql server, having previously used mysql. How do i make a auto number field? What datatype shall i use for it? like autonumber for mysql. Ive tried setting my primary key field to uniqueidentifier data type but then i still need to manually add a guid key in there. i want it so it automatically generates a unique key everytime i add a new row. is this possible?!hope someone can help!thanks

Link ( GroupID int , MemberID int ) Member ( MemberID int , MemberName varchar(50), GroupID varchar(255) )
The Link table contains the records showing which Member is in which Group. One particular Member can be in multiple Groups and also a particular Group may have multiple Members.
The Member table contains the Member's ID, Member's Name, and a Group ID field (that will contains comma-separated Groups ID, showing in which Groups the particular Member is in).
We have the Link table ready, and the Member table' with first two fields is also ready. What we have to do now is to fill the GroupID field of the Member table, from the Link Table.
For instance,
Read all the GroupID field from the Link table against a MemberID, make a comma-separated string of the GroupID, then update the GroupID field of the corresponding Member in the Member table.
Please help me with a sql query or procedures that will do this job. I am using SQL SERVER 2000.
hi 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?
There are two tables, parent and child table.Foreign key field of the child table is not a required field. If thedata is submitted w/o a value into the foreign key field, what shouldI make it as a default value? Should it be "null"?
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)
When I ran the report from the browser (not from the preview when designing the report), the parameters and the View Report button still displayed. I noticed clicking a double arrow button can hide or show the parameter section . How can I make hiding the parameter section as default? Currently showing the section is the default.
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? Below is an example of what i'm trying to do (Field_C is the new field and i want it to use Field_A value if no other value is specified on insert). Any help would be greatly appreciated.
alter table FOO add Field_C varchar(50) not null constraint FOO_default DEFAULT Field_A
Hi, I have asked this question on 3 forums now and never get an answer, I don't know what is so hard about this question but I will try it here. I am using SHA512 in C# to convert a password and its salt to hashed. I need to store the password hash and the salt hash in the database in two fields. I was told to use binary field to store the hash data and that the output of SHA512 would ALWAYS be the same no matter how long the password is. I modified this hash example to use only SHA512 and to work with byte array instead of plain text. All I need to know now is what size I need to make my binary field to hold this password that is hashed. http://www.obviex.com/samples/Code.aspx?Source=HashCS&Title=Hashing%20Data&Lang=C%23 Say I have a password which is 30 characters max, and a salt which is 16 characters max. The password and the hash are stored in seperate fields in the same table. They are both hashed using SHA512 and are both being stored as byte arrays in C#, what size to I need to make the binary data type in order to hold the password, and to hold the salt. Thanks!
Hi there! I'm using a Switch statement in my SQL as follows:
Code:
SELECT symbol, Switch(timestamp Is Null,Null, timestamp <= 005959, 0, timestamp<=235959,23) AS period INTO averageprice FROM stocktrades;
Now here's my problem. The Data Type stored in the 'period' field of this new table I've created, dubbed averageprice, is a Text field and I want it to be a Number field. I've tried my best to figure this out and I'm still looking so any helpful hints or solution would be greatly appreciated. Thanks!!!
is there any way i can make a field in a table accomodate more than 1023 charcters? i used the 'varchar' datatype and used a length of 2500, but still, I can't fill up a field with more than 1023 characters. Is there any way to change it? Also, is there any way to used a symbol or special character in a field? Can SQL server identify such a character? like the alpha or beta symbol...
Hi, SELECT UserID, UserName, Password, PublisherID, CurrencyFROM [User]WHERE (Password = 'Anitha') I am using the above mentioned it is working but int the password field i had given it as anitha. Now the querry is retriving the record for anitha, it shouldnot happen. The querry should retrive the record of anitha only for where condition anitha and not for Anitha or ANITHA etc.. Thanks Vishwanath
I have a table where i have to make a check constraint that states the first 3 characters of the customerid field must be the first 3 characters of the company name I am so lost I looked everywhere.
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!
hi, please help me, i have a data driven site, i made a field that i call "Status"so this is how it should happens, there are three different gridviews in a single page, gridview1 filter is [status] = ok, gridview2 filter is [status] = fine, gridview3 filter is [status] = complete, so all gridview has its own <asp:hyperLinkField> at first the value of "Status" is ok, so it will appear in the gridview1, so when the user click on the <asp:HyperLinkField> of gridview1 it will go to a new page with a form view, this page has a button that when click will change the value of the status field to "fine", so that it will no longer appear to the gridview1 but it will now appear to gridview2 and same with the next <asp:HyperLinkField> click until it appears to the final gridview. so my question is how can i make the button that is capable of changing (update) the value my database field (status) to a specific value, that is not visible to the user thru codebehind or plain asp.net codes. please help me, if you need more info just reply.ThanksSALAMAT PO!
Hi guys, I need to get a column with the sum of the field "SUF" from table "JurnalTransMoves_1" when that field ("SUF") is ordered by the field "REFERENCE" from table "Stock", and Show the value only once.
The desired result should by something like:
Stock.REFERENCE JurnalTransMoves.SUF SUM(JurnalTransMoves.SUF) Group By Stock.REFERENCE
5752 10 60
5752 20
5752 30
5753 400 3000
5753 500

In SQL Server 2000 / Asp.Net I am trying to use default values for all fields; hoping to eliminate nulls.
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?
I am creating a new filed in SQL Server 2005, and I want the field to have the default of '0'
I select the data type as numeric and save my changes, I then visit our front end database to see if the default value is just '0' but it appears as '0.00'
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'
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.
We want to add a default date to our database tables. Looking at other database samples people use all sorts of dates to add as default date e.g. 1/1/1997 or the getdate() function. Is it good practice to set a default date and what should the default date be???? Newbie
I am working with a SQL server 2005 database. I have created several new tables. In one of the tables, I need to set up a data field so that it will default to a particular value. For exampe, I need to have a particular data field default to a value of '0' How can I do this? I would prefer not to do this through Query analyzer. I have been using the interface to SQL server 2005 provided through the Visual Studio IDE. Thanks in advance, Bill
Is there a way to set a field value to the column default in an update statement? Eg. UPDATE Table2 SET field1 = DefaultValue where DefaultValue is the field1 column default in the table definition. The reason I need to do this is when I delete a record from Table1, I need to set the foreign key in Table2 to the default (I don't want to delete the record in Table2, just want to set the key to a default key). I could hard-code the default value in the stored procedure but I think that's just not clean. If I create a new instance of the DB and the default value changes, I'd need to change the stored procedure(s). Just not clean... To avoid a drawn-out discussion, there are reasons why I can't setup a relationship between the two tables and use "ON DELETE SET DEFAULT". Any info greatly appreciated.
For reasons that are not relevant (though I explain them below *), Iwant, for all my users whatever privelige level, an SP which createsand inserts into a temporary table and then another SP which reads anddrops the same temporary table.My users are not able to create dbo tables (eg dbo.tblTest), but arepermitted to create tables under their own user (eg MyUser.tblTest). Ihave found that I can achieve my aim by using code like this . . .SET @SQL = 'CREATE TABLE ' + @MyUserName + '.' + 'tblTest(tstIDDATETIME)'EXEC (@SQL)SET @SQL = 'INSERT INTO ' + @MyUserName + '.' + 'tblTest(tstID) VALUES(GETDATE())'EXEC (@SQL)This becomes exceptionally cumbersome for the complex INSERT & SELECTcode. I'm looking for a simpler way.Simplified down, I am looking for something like this . . .CREATE PROCEDURE dbo.TestInsert ASCREATE TABLE tblTest(tstID DATETIME)INSERT INTO tblTest(tstID) VALUES(GETDATE())GOCREATE PROCEDURE dbo.TestSelect ASSELECT * FROM tblTestDROP TABLE tblTestIn the above example, if the SPs are owned by dbo (as above), CREATETABLE & DROP TABLE use MyUser.tblTest while INSERT & SELECT usedbo.tblTest.If the SPs are owned by the user (eg MyUser.TestInsert), it workscorrectly (MyUser.tblTest is used throughout) but I would have to havea pair of SPs for each user.* I have MS Access ADP front end linked to a SQL Server database. Forreports with complex datasets, it times out. Therefore it suit mypurposes to create a temporary table first and then to open the reportbased on that temporary table.
