I have just started studying for an MCTS, to eventually get to MCITP for SQL Server 2k5.
I am currently in an Application Support position, working with a large clinical Oracle Database, but mainly on a simple querying basis.
The plan is obviously to get away from the Tech Support, towards the DBA and I have been researching the current job market and never once found a job offer that said "offering an entry level or Junior DBA position for those that are just starting"... There's always at least a few years of experience already as a DBA required!
I am wondering how one is supposed to get that experience if he doesn't get a beginners position to start off with?
Any stories from experience? Any hints where to look, how to apply and where maybe?
AA Guyz i want to calculate class position of students from a table.Sample data is as follows...Roll # - Name - Marks1 - ABC - 602 - DEF - 603 - GHI - 574 - JKL - 555 -MNO - 506 -PQR - 53The query should return the following result.Roll # - Name - Marks - POSITION1 - ABC - 60 - 12 - DEF - 60 - 13 - GHI - 57 - 34 - JKL - 55 - 45 -MNO - 50 - 56 -PQR - 53 - 6I want query in MS SQL Server 2000
I want to create a procedure where each time I add a new record to a table I want to set the field “Display” ( BIT ) to “false” in a position that is two rows before the last one. How to do that ?
PRINT cast(111 as decimal(38,35)) / 23 --> 4.82608695652173913043478260869565217
then here
DECLARE @Zähler decimal(38,35) , @Nenner decimal(38,35) SET @Zähler = 111.0 SET @Nenner = 23.0 PRINT cast(@Zähler as decimal(38,35)) / @Nenner --> 4.826086
Of course, in the upper part 23 is implicitly an integer, in the lower example it is declared as decimal. But what if I need to devide by 23.5? Why is dividing by an decimal reducing the results decimal positions?

I'm in stage of manually populating a database that requires me to have about a dozen tables open simultaneously. It would be great to be able to save the tables, locations and sizing so that these can be recalled and opened automatically. Currently I do a screen capture, which is pretty lame.
Any suggestions would be welcome.

I have got code for single string... but i want to encrypt/decrypt columns and sometimes the whole database... Can anybody help me out... If you have Store procedure in SQL for the same then also it ll do... Thanks in advance
When you utilize transactions in ADO.NET are the locks put on the entire TABLE used or at the row level? For instance if you do a SELECT within a transaction if you only pull 5 rows out of a 1000 row table can you just make it lock the rows that have been pulled? It seems like it locks the entire table?
Hi, Can anybody please explain me, what is low level and high level locking in SQL Server 2005 database. Also what is the name of process which converts low level locking into high level locking and vise versa. -Sanjeev
Hi..I'd very much appreciate it if someone would tell me how to translatea statement level trigger written in Oracle to its equivalent (if there isone)in MS SQL Server. Ditto for a row level trigger.If this is an old topic, I apologize. I'm very much a newbie to SQL Server.Regards,Allan M. Hart
The relationship between state and sales region is n:1, i.e. one state belongs to exactly one sales region, and one sales region can consists of one or multiple states. Unfortunatly I can't define this attribute relationsship in the dimension because it would lead to a diamond-shaped relationsship without a user-defined-hierarchy to back it up. So far that isn't much of a problem, user don't drill down from sales region to state. But now I want to define a calculated member that multiplies a measure from the main measure group with another measure from a weighting factor measure group at the state level and above. The granularity attribute of the geography dimension in the dimension usage tab of the weighting factor measuregroup is the state.
So far what I've got is:
CREATE MEMBER Currentcube.Measures.[weighted measure state and above] AS NULL; SCOPE (Measures.[weighted measure state and above], Descendants(geography.[political territory].[all member],3,SELF_AND_BEFORE), Descendants(geography.[salesterritory].[all member],2,SELF_AND_BEFORE), ... Descendants(geography.[hierarchy 9].[all member],1,SELF_AND_BEFORE)); this = sum(existing(geography.[political territory].state.members), measures.[main measure group measure] * measures.[weighting measure group measure]);END SCOPE;
This works from a functional point of view, but is rather slow when querying any other hierarchy than the political territory hierarchy, because SSAS first goes down from the state level to the key attribute of the geography dimension, and then aggregates from there to the sales region.In other words, I want SSAS to resolve the relationsship (which state belongs to which sales region) through the dimension, and not through the fact, and apply the calculation afterwards. Like some kind of currency conversion, but only from a certain level upwards.
Can someone please help me solve the following error? I am not sure of the version my hosting company is using and where to get the manual. Could not add the entry because: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '-id, title, entry, date_entered) VALUES ('testing', 'testing', . The query was INSERT INTO blog_entries (blog-id, title, entry, date_entered) VALUES ('testing', 'testing', 'testing'.
PHP Code:
if ($dbh = mysql_connect ('localhost', 'blu6592_money', 'rich')) { print '<p>Successfully connected to MySQL.</p>';
if (mysql_select_db ('blu6592_myblog')) { print '<p>The database has been selected.</p>'; } else { die ('<p>Could not select the database because: <b>' . mysql_error() . '</b></p>'); }
if (mysql_query ($query)) { print '<p>The blog entry has been added.</p>'; } else { print "<p>Could not add the entry because: <b>" . mysql_error() . "</b>. The query was $query.</p>"; }
} else { die ('<p>Could not connect to MySQL because: <b>' . mysql_error() . '</b></p>'); }
(I don't post here often, so in case I'm violating long-standing taboosof this newsgroup, I apologize in advance for calling a relation atable, using nulls, and other ignorant, destructive, and comtemptibleterminology.)I have a table that's keeping a sort of running log of different typesof changes to pieces of data. The table has a foreign key of the databeing changed, the foreign key for the type of change occuring, someinformation about the change in a couple more columns, and a timestampfor each entry. So it's:dataIDeventIDeventInfotimestampWhat I'd like to do, if at all possible, is a single SQL query that,given a dataID, returns the most recent eventInfo and timestamp foreach eventID. Is this possible?Many thanks.-Eric
"High priority system task thread: Operating system error Exception 0xAE encountered."
we are seeing this on one of our development servers, running SQL 2005 Enterprise SP1. The symptom is that after the sql service has been running a while (order of days), this error starts getting written to the sql server log file over and over, and eventually the logfile fills the drive.
Apparently it's fixed by this hotfix, but our ops team doesn't want to install this - they'd rather just cycle the service and delete the log when it happens.
I was wondering if anyone else has seen it might know the root cause so we might be able to workaround it without cycling the service. I know, lame question. The correct answer is "install the hotfix" or "install sp2" but our ops team won't do that for now...
I have a table with name C1_Subscribers with three fields (1)-MobileNumber [varchar] (2)-ReceivedTime [datetime] (3)-Status [char]. Now here how to remove duplicate entry of same mobile number to MobileNumber field?
Hello, I have a table of names/dates as such: Class 1 1/1/2007Class 1 1/3/2007Class 1 1/5/2007Class 2 2/1/2007Class 2 2/3/2007Class 3 3/1/2007 What I want to do is select only the nearest entry from the list for each distinct class, so the results are like this: Class 1 1/1/2007Class 2 2/1/2007Class 3 3/1/2007 So basically, I want the first upcoming class in the list for each distinct class name. How do I do this? I'm using SQL 2005 Express. Thanks.
How do i do that... in sch lab, the lecturer said: Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Try SqlDataSource2.SelectParameters("Title").DefaultValue = txtProductTitle.Text GridView1.DataBind() If GridView1.Rows.Count > 0 Then //if no repeated Label1.Text = "Existing Record Found. Please enter another Software." Else 'SqlDataSource1.Insert() 'Label1.Text = txtProductTitle.Text & " successfully added to the database." End If Catch ex As Exception Label1.ForeColor = Drawing.Color.Red Label1.Text = "An error occured!" & ControlChars.NewLine & ControlChars.NewLine & _ ex.Message.ToString() End Try End Sub but its not working for me... the GridView1.Rows.Count is always 0, if there is a repeat, it should be > 0
Hi, I know this is probably very simple but I am pretty new to this and have tried looking but cant seem to get the search criteria right. I have a database with a storeDate field which is of shortdatetime type. I am connecting to the database (MSSQL) via a stored procedure and returning all the records. I then use the code foreach (DataRow dr in ds.Tables[0].Rows) { DateTime dtTo = DateTime.Now; DateTime dtFrom = DateTime.Parse(dr["storeDate"].ToString()); TimeSpan diff = dtTo.Subtract(dtFrom); } I am basically trying to find out the age of the database entry by subtracting it from the current DateTime so i can delete records over a certain age. The problem (at least one of them!) is retrieving the "storeDate" object from the database and storing it in the dtFrom object. I have tried just assigning it directly as dtFrom = dr["storeDate"] and various other methods but I just don't know enough to assign it! Can anyone help me with this or spot any other mistakes in this process of removing old files automatically. Greatly Appreciated,Sean.
Hi,I'm creating a database using SQL Server 2005 Express Edition (Comes with Visual Web Developer). The table which I am creating has the following Fields - all don't allow nulls:IDUserIdDateDescription(UserId is a foreign key to asp_net_Users as I am supporting user accounts)Basically what I need to do is create a page where I as an Administrator can log onto and enter just the text for the field Description. Then once I upload this I wish all users to visit the site and view this Description on a page however with it also listing the Administrator who wrote it along with the Date. I wish both of these fields to be added automatically (UserId to display the User Name and the Date to display the date and time with which the Description was added - However these need to be editable by the Administrator if he/she wishes to change them).Can anyone point me in the right direction on the steps needed to create this scenario?Thanks for any helpDaniel
Here's some code that says it should identify if a user already exists in my database. I have changed the code to match my database, but it seems to have somewhat the opposite affect, rejecting all names (even new ones) or accepting all names (including existing ones). The switch in situations occurs in the "if" statement towardsd the end, when I change the sign of objDR.RecordsAffected. Do you have any idea what could be wrong? Thanks. Function DoesUserExist(ByVal userName As String) As Boolean Dim connectionString As String = "server='(local)Netsdk'; trusted_connection=true; Database='AuthorizedUsers'" Dim sqlConnection As System.Data.SqlClient.SqlConnection = New System.Data.SqlClient.SqlConnection(connectionString)
Dim queryString As String = "SELECT [Users].[UserName] FROM [Users] WHERE ([Users].[UserName] = @UserName)" Dim sqlCommand As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand(queryString, sqlConnection) Dim Cmd as New SQLCommand(queryString, sqlConnection) With Cmd.Parameters .Add(New SQLParameter("@username", username)) End With
sqlConnection.Open Dim blHasRows As Boolean Dim objDR As System.Data.SqlClient.SqlDataReader = Cmd.ExecuteReader(system.data.CommandBehavior.CloseConnection)
if objDR.RecordsAffected > 0 then blHasRows="True" else blHasRows="False" End If
To insert entries into a table. The table has a primary key based on a field 'ID'. When inserting into the destination table, I want to make sure that the new entry will overwrite the old entry.
Howdy all. Im trying to write a query that will track a data modification grouped by employer ID and transaction date. I don't know if Im asking it right so here is what I have, plus my current and desired outputs.
Newbie here, just wanted to get that out of the way first and foremost.
Im trying to set up a DB in SQL 2000 that allows me to enter lots of text into a column.
I read one site where it said to use the NTText datatype with a length of 16. I did that, but everytime I enter alot of text into that column I get <Long Text> and I dont know how to output that or even read it.
Do any of you guys know how to either:
1. get the text out of the <long text> or 2. a better way to store that much data.
Hey there, could someone please help me!! I had created a database in sql server but since then installed windows xp pro and now when i go through the microsoft sql server dsn configuration the database is not valid and therefore i cannot change the default database as it says it doesn't exist. So then when i type in command prompt use 'db' it says it doesn't exist but when i try to create 'db' it says that the database already exists. I get the error message, could not locate entry in sysdatabases for 'cti' (database name). When i look in mysql - data - along with master etc there is my cti.mdf and log files?? I'm stuck??? Is it that the files just aren't registering through sql server??? Please help!
I have the following situation: I have a table that is log of transactions of useractions. Each time a userstatus changes, a new entry is made into the table.
The table has (currently) about 4 million records, and keeps growing each day with thousands of records. It logs the status of about 150 users (currently active).
What I now want is to get the log-entry from all the distinct users that have a log-entry on the latest day (so current day, 'where TimeStamp > 2008-04-08').
(extremely simplified) Example: (date is y/m/d)
USERID TIMESTAMP STATUS ---------------------------------------------------- ... (thousands and millions of records above) Ed 2008-04-07 18:00:00 Logged_Out Jim 2008-04-07 18:30:00 Blabla_Status_5 Jack 2008-04-07 19:00:00 Logged_Out Jim 2008-04-07 19:30:00 Logged_Out Jim 2008-04-08 06:00:00 Logged_In (<< notice new day) Jim 2008-04-08 06:01:00 Blabla-Status_1 Bob 2008-04-08 06:03:00 Logged_In Fred 2008-04-08 06:05:00 Logged_In Jim 2008-04-08 06:08:00 Blabla-Status_2 Jack 2008-04-08 06:12:00 Logged_In Fred 2008-04-08 06:20:00 Blabla_Status_5 Jack 2008-04-08 06:12:00 Logged_Out Fred 2008-04-08 06:12:00 Blabla_Status_4 Jack 2008-04-08 06:12:00 Logged_In Jack 2008-04-08 06:12:00 Blabla_Status_7 ----------------------------------------------------
The result should be:
USERID TIMESTAMP STATUS ---------------------------------------------------- Jack 2008-04-08 06:12:00 Blabla_Status_7 Fred 2008-04-08 06:12:00 Blabla_Status_4 Jim 2008-04-08 06:08:00 Blabla-Status_2 Bob 2008-04-08 06:03:00 Logged_In ----------------------------------------------------
I have an online store with products and categories. The requirements are: Each product can be in one or more categories; a product must be in at least one category.
To accomplish the first requirement, I have a Product table, Category table, and a many-to-many Product2Category table. (Probably not relevant, but a requirement is the Category table is self-referencing to provide sub-categories.)
My question is for the second requirement that each Product be in at least one category. My assumption would be to add a column to the Product table called "ParentCategoryId", which is a foriegn key of the Category table's identity column.
What would be the best approach to ensure a product is in at least one category?
