I Know This Is Easy But...
Jun 9, 2004
I'm banging my head against the wall. It's probably pretty simple so here goes...
I have a form that supposed to add records to a table on the database. I'm pretty sure I have the dataAdapter and Dataset set right but when I add a record, it complains that the primary key can’t be null. I’ve tried different things, including removing those fields and variables from the stored Proc, changing the Identity Properties of the Table, changing the AutoIncrement settings on the Dataset for that field, but all give me different errors. Nothing actually makes it work. This database has many records in it and the Primary key is a decimal field that starts at 5, then next was 10, then 28, then it started getting consecutive after 110. (111, 112, 113, etc.) (I'm porting over an old database to a new web site, so I'm somewhat contrained by the database.)
I guess my question is for adding records in to a database that has a primary unique key constraint. Certainly this is a pretty common thing. Obviously I do not want users to enter that in themselves, I thought it should simply autocreate/autonumber. So what is the best procedure and gotcha’s I need to watch out for?

if i have the following code, how do i know if the transaction was actually successful, so basically where in this code can i write TRANSACTION SUCCESFUL?
try
{
//Open up the connection
conn.Open();
//Setup the Transaction
trans = conn.BeginTransaction();
//First query in transaction
pre_query = "Delete from Menu where spec_name="
+ "'"
+ spec_name_array[i].Text.ToString()
+ "'" ;
//Second query in transaction
query = "INSERT into Menu VALUES ('"
+ Calendar1.SelectedDate
+"','"
+ spec_name_array[i].Text.ToString()
+"','"
+ spec_desc_array[i].Text.ToString()
+"','"
+spec_price_array[i].Text.ToString()
+"',1)";
SqlCommand comm = new SqlCommand(pre_query,conn);
//Setup the command to handle transaction
comm.Transaction = trans;
//Execute first query
comm.ExecuteNonQuery();
//Add in second query
comm.CommandText = query;
//Execute second query
comm.ExecuteNonQuery();
trans.Commit();
}
catch(SqlException ex)
{
com_label.Text = "Submission Not complete, did you forget the date or something else?";
//Undo all queries
trans.Rollback();
}
finally
{
conn.Close();
}

This may not be the right place for this post...but my head is hurting and I can't think right now.
I have a SQL table of users. Each record has a required 'Birthdate' field. I'd like to order this by the days left till the give birthday, keeping in mind that the year may be 1980 or their birthday might have been 2 weeks ago.
Can someone cure my headache?

I have written 2 custom connection mgr€™s.
One connects the data from an oracle source
One connects so I can put the data on a sql server.
These both work well and it makes it a lot easier across development, test, production.
But now I would like a good way to do this
I have 10 tables to copy from oracle. The only difference is just the name of the table.
static string[] g_tables =
{
"table_name_1",
"table_name_2",
"table_name_3",
€¦
};
foreach (string str_table in g_tables)
{
Oracle.DataAccess.Client.OracleCommand OracleCommand = new Oracle.DataAccess.Client.OracleCommand
(
"select * from " + str_table,
OracleConnection
);
Oracle.DataAccess.Client.OracleDataReader OracleDataReader =
OracleCommand.ExecuteReader();
// dump out to raw file destination
}
I understand there are some pieces left out but that is the basic idea. It seems like I€™m going to have write custom pieces for each step.
It does not seem like there is any advantage to using SSIS. Should I give up now and stick to writing windows services for stuff like this?
I could just write a specific piece for each table but the only difference is the table name.

I completely forgot how to do this. I want one of my groups in the matrix to take its week number (1-7) as Monday-Sunday.
so it would kind of be like this:
=IIF(Fields!DayOfWeek.Value=2,"Mon",
ELSE(Fields!DayOfWeek.Value=3,"Tues",
Else(Fields!DayOfWeek.Value=4,"Wed",
etc etc
Am i doing this right, or am i off??

I have a column in my report that i want to show percentage change from the previous year to this year. So i enter all kinds of different type of formats for the formula, and keep getting the wrong answers or error messeges. Here's what i have tried recently:
=SUM((Fields!LYTD_Amount.Value - Fields!YTD_Amount.Value) (Fields!YTD_Amount.Value*100))
Its pretty much Last year to date Minues Year to Date , Divided by Year to Date, Multiplied by 100.
any suggestions? Everytime i try to put an aggregate in the box, its always tricky.

Ok - I am still a bit weak on SQL. My understanding of FK relationships in a database are to reinforce the data integrity - Correct? For example, does it make sure that the id given for SiteID does indeed exists. Can it link tables like JOIN in select statements? If not, is there any gains by creating them, such as performance?

scenario I have 2 tables one is called "Site" which contains columns ID, Address1, Address2,City,StateID,ZipCode and the second table is called "State" which contains columns ID,Name,Abbreviation. I am looking to make a view that contains all the sites with the state inner joined on stateid to make my all my other queries easier. That is so I can just select from the view without having to do the inner join on the state. My question is when a new record is added to table Site do I have "recreate"/update the view?

I have a simple SQL table. The data looks like this:
products_ID----category----product_local
1----CORE----0
2----BASE----0
3----BRANCH----1
4----LEAF----3
I need to create a SQL statement that produces all category items where that ROW's products_ID is not found in ANY product_local in the table. So in the table above only the category BASE and LEAF would be printed because their products_ID are not found in any product_local in the table.
TIA as I am completely stuck!

OK, I have two cols of data:

I need to simply pull one row of data from the given rows. Whats in COL2 is not relevant. So an example would be:
I want to retrieve a row(any row, but only one) where COL1 = 'test'
An ecceptable result woould be:
COL1 COL2
test ing
or
COL1 COL2
test pan
or
COL1 COL2
test ut
I would appreciate any help. This is driving me nuts. Seems like it would be easy.
TIA,

Hi,
the following Insert statement is not acting like i would expect it. The final column (Average) divides two columns([Sum of Scores] / [Count Of Scores]) . The Average column is a numeric column with 5 decimal places. Yet, the result of the division is a whole number (no fractions). Why is this.
any help would be appreciated
Thanks,

I have a ASP page where the user posts part of the name field. Then i need to provides the matches. (providing partial comparision of the field & correcting bad spelling)
example:
User posts 'softwair' (should be software)
the query look like this
Select Name from A where Name is like '%softwair%' <-- but appling soundex on it in the like field, or something like it.
I could make a copy of the column and update all info in the field to the soundex value, but then the like statement would not get it if the value was only part of it. for example say the data values where like 'Microsoft Software', or 'My Software Solutions', ect...

Hey all,
A nice easy BCP question for y'all...
I'm currently running:
DECLARE @sql varchar(2000)
SET @sql = 'BCP master..sysobjects OUT C:sysobjects.csv -c -t, -T -S' + @@ServerName
EXEC master..xp_cmdshell @sql
Which works fine!
But how on earth do I save it to my local PC?
May sound silly, but this is one of my first adventures into BCP and I'd rather not "pollute" the server with my test files!
Thankyall!

I'm used to forming Select statements for IBM System i imbedded SQL in High Level source programs. I now find myself converting System i RPG programs to VB.NET classes. What I want to know is how to insert the value of a class variable into a SQL Select string. In the IBM world, I would do:
Select STCTYC,STCRID,STTITL,STSTTY From CSLSTT01 Where STCTYC = :County
where County is a program defined variable. How do I get the value in the County variable into the Select string? I tried concatenation but that didn't work either. Thanks.

Hi,
I have a query that I need to pass as a string as the second parameter of the OpenQuery method. Here's my query:
SELECT * FROM mytable WHERE last_name = 'DOE'
Thing is that a string is set with apostrophies, so I don't know how to set my string since apostrophies are alse in my query. Normally, it would look like this:
DECLARE @CQUERY VARCHAR(100)
SET @CQUERY = 'SELECT * FROM mytable WHERE last_name = 'DOE''
But of course this fails. How can I do it then?
Thanks,
Skip.

I've read some post that highly recommend not putting a clustered pk on identity columns. Rather use a non-clustered pk for identity pk columns. Does anyone have opinions about this? I have several reference tables that have the following structure. Since joins are made on the pk column I would guess that it would be beneficial to make the pk the clustered index, then again maybe it's better to make one of my unique indexes clustered. Any thoughts?
CREATE TABLE [company] (
[company_id] [int] IDENTITY (1, 1) NOT NULL ,
[co_abbrev] [char(10)] NOT NULL ,
[co_name] [varchar(50)] NOT NULL ,
CONSTRAINT [pk_company] PRIMARY KEY CLUSTERED
(
[company_id]
) WITH FILLFACTOR = 90
)
CREATE UNIQUE INDEX [ux_company_01] ON [dbo].[company]([co_name]) WITH FILLFACTOR = 90
CREATE UNIQUE INDEX [ux_company_02] ON [dbo].[company]([co_abbrev]) WITH FILLFACTOR = 90
