Check Values Record By Record

Nov 14, 2007

Consider this scenario.

I have two database in the sql server and consider that i have a query which has 4 tables inner joined.

When i execute the query in the database1 , the query is returning rows, But when  i execute the same query in the database2, the query is not retuning rows . I know that the

no rows are returned because of missing data in the database2. But have no idea how to trace what values are missing in the database2. Please note the tables is having a huge

list of records by which manually comparison is painfull. Please consider i dont have any background idea of the values in the tables but just using it. Any help would be

How To Check Previous And Next Record Values

May 22, 2008

Hi all,

I wanted to check the previous and next record values.

For example:

sKey NextKey PreviousKey

1 2 Null
2 8 1
8 5 2
5 null 8


Ex : In the first record of the table, the NextKey is pointing to 2.
So the next record of Skey will be 2. The Next Key for this record is 8. Like wise the next record of this should have the Skey as 8.

Now I need to check whether the NextKey and SKey are correct for all rows.

For that I need to check the previous record of "Next key" and next record of "Skey".

Any idea?

Regards
Helen

Check If Record Exists

Feb 1, 2007

 Hello,I created the following SQL script to check if a record exists:IF (EXISTS (SELECT LevelName FROM dbo.by27_Levels WHERE LOWER(@LevelName) = LOWER(LevelName)))  Return (1)ELSE  Return (0)And I also found in a web page another solution:IF EXISTS(SELECT 1 FROM TABLENAME WHERE LevelName=@LevelName)  SELECT 1ELSE  SELECT 0- Which approach should I use?- Why "SELECT 1 FROM"?- And when should I use SELECT or RETURN?All I need is to know if the record exists ... nothing else.I will use this procedure on an ASP.NET 2.0 / C# web site.I am not sure if this important but anyway ...Thank You,Miguel

Check For Primary Key Before Inserting New Record

May 17, 2005

Hi,
Can someone please tell me the best practices for checking the primary key field before inserting a record into my database?
As an example I have created an asp.net page using VB with an SQL server database.  The web page will just insert two fields into a table (Name & Surname into the Names table).  The primary key or the Names table is "Name".   When I click the Submit button I would like to check to ensure there is not a duplicate primary key.  If there is return a user friendly message i.e. A record already exisits, if there no duplicate, add the record.
I guess I could use try, catch within the .APSX page or would a stored procedure be better?
Thanks
Brett

Creating A Trigger To Check Before Deleting A Record

Jun 12, 2008

I am using the tables created by the aspnet_regsql.exe tool for security.  Basically, I need to ensure that an account named Administrator is never deleted.  I also have a role named administrator, and I need to make sure that Administrator is never removed from the administrator role.Can I create a trigger to ensure that the Administrator is never deleted and that the Administrator is never removed from the Administrator role?  I know it will probably be two separate triggers: one on the aspnet_users table and one on the aspnet_usersinroles table.Thanks a lot for the help!

SQL Server 2012 :: Check To See If Columns Are NOT NULL In A Record

Jun 25, 2015

I am looking for the best way to check to see if any columns are still NULL in a record. I have a form that gets filled out by users and the values entered into TableA. There are 6 columns in the table, 5 are responses and column6 indicates if the record is complete. So I want a way to see if all of the first 5 columns are NOT NULL and, if so, mark column6 with a 1.

I am thinking this would be a good thing for a trigger on INSERT or UPDATE to check to see if the first 5 columns are filled in and then mark the record as complete.

Ways To Make This Work: Several Selectable Related Record For One Main Record.

Apr 6, 2007

Hey all!



Sorry for the less then descriptive post title but I didn't find a better way to describe it. I'm developing an app in the express editions of VB and SQLserver. The application is a task/resource scheduler. The main form will have a datepicker or weekly overview and show all tasks scheduled per day. The problem is, I've got one or more people assigned to tasks and I wonder what's the best way to design this. Personally, I'd go for one Task table, a People table and a table that provides a link between them (several record per task, one for each person assigned linking TaskID and PplID). However, I don't see a nice way of showing this data to the end user, allowing him to edit/add etc on ONE screen.

To fix that the only way I see is just add columns to the Task table for every person with select boxes. This way everything can be done on one simple screen. This obviously does present some future issues.

On top of this, which people are available on a day varies and there should be an option to allow a user to set who is available on a specific day. Which would lead me to my first idea and add another table that would provide this. but then I'm having design issues again for the form.



I'm kinda stuck atm, can anyone shed some light on this. I'm sure there is an elegant way of doing this but I'm failing at finding it.



Thanks in advance,

Johan

Query Timeouts When Updating A Record Retrieved Through A Websphere JDBC Datasource - Possible Record Locking Problem

Apr 7, 2008

Hi,

We're running a Sage CRM install with a SQL Server 2000 database at the back end. We're using the Sage web services API for updating data and a JDBC connection to retrieve data as it's so much quicker.

If I retrieve a record using the JDBC connection and then try and update the same record through the web services, the query times out as if the record is locked for updates. Has anyone experienced anything similar or know what I'm doing wrong? If I just use DriverManager.getConnection() to establish the connection instead of the datasource, and then continue with the same code I don't get these record locking problems. Please find more details below.

Thanks,
Sarah

The JDBC provider for the datasource is a WebSphere embedded ConnectJDBC for SQL Server DataSource, using an implementation type of 'connection pool datasource'. We are using a container managed J2C authentication alias for logging on.

This is running on a Websphere Application Server v6.1.

Code snippet - getting the record thru JDBC:


DataSource wsDataSource = serviceLocator.getDataSource("jdbc/dsSQLServer");
Connection wsCon = wsDataSource.getConnection();


// wsCon.setAutoCommit(false); //have tried with and without this flag - same results

Statements stmt = wsCon.createStatement();


String sql = "SELECT * FROM Person where personID = 12345";
ResultSet rs = stmt.executeQuery(sql);


if(rs.next()){
System.out.println(rs.getString("lastName"));
}

if (rs != null){
rs.close();
}
if (stmt != null) {

stmt.close();
}
if (wsCon != null) {

wsCon.close();
}

SSIS: Multi-Record File Extract With 9 Record Types

Feb 26, 2008

I am attempting to create a multi-record file (as described in my last thread) and have found the following set of instructions very helpful:
http://vsteamsystemcentral.com/cs21/blogs/steve_fibich/archive/2007/09/25/multi-record-formated-flat-file-with-ssis.aspx

I have been able to create a sample file with two of my record types.

I now need to build on this further, because I have 9 record types in total that need to be extracted to a single flat file.

does anyone have any ideas how I might extend the example above to include more record types or know of another means of achieving this?

Thanks in advance for any help you might be able to provide.

Integration Services :: Check Table For Existing Record Before Data Flow Task

Jun 1, 2015

Using SSIS 2012 (within Visual Studio) on Windows 7.

Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate"). 

Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?

Changing Values In A Record

May 2, 2004

I have the problem of dynamically changing a field value in a row depending on the value of the same field in the previous row, assuming the table is sorted on that field.
:(
You may consider that field as a key of same sort as other values in the table do not help in selecting them uniquely.
Ex.
Before After
130 -> 130
130 -> 130A
140 -> 140
140 -> 140A

Editing A Sql Record That Contains NULL Values

Mar 25, 2008

Seems that when i use the edit functionality of the formview, and there are NULLs in the record, that my sql update statement (default from the FormView wizard) doesnt work (nothing updates). However, if i populate all fields, everything works fine. I have modified the FormView edit template to add my own textboxes and dropdowns to simplify the user record editing. 
Because it works when all fields are populated with non-NULL values, Seems my Bind's are all correct.

Retrieve When All Values In Group Have Same Record

Feb 25, 2015

Here is some sample data:

CREATE TABLE
#MyTable
(
Pk INT,
GroupID INT,
Value VARCHAR(10)

[code]...

I am looking to retrieve any GroupID in which every Value of that GroupID is either (a) null, (b) an empty string, or (c) "XYZ". So in the above example, GroupID #1 would not be returned in my query because there is a Value of "ABC", but GroupID #2 would be returned since it consists of only nulls, "XYZ"'s, and empty strings.What would be the most efficient way to write such a query?

Fast Way To Get Values From Previous Record

Jul 20, 2005

Hello,I know that I've seen this question asked on here before, but I can'tfind an answer that gives me the performance that I need.I have a table that stores events for users:CREATE TABLE Lead_Action_History (lead_action_seq INT IDENTITY NOT NULL,lead_action_date DATETIME NOT NULL,lead_seq INT NULL,operator_id VARCHAR(20) NOT NULL,call_time INT NOT NULL,CONSTRAINT PK_Lead_Action_History PRIMARY KEY (lead_action_seq) )GOThe table has a foreign key to another table through the lead_seqcolumn:CREATE TABLE Lead_Master (lead_seq INT IDENTITY NOT NULL,state CHAR(2) NOT NULL,CONSTRAINT PK_Lead_Master PRIMARY KEY (lead_seq) )GOI need to write a query that will give me a sum of call_time brokendown by a column that is in the table joined through the lead_seq.However, if the lead_seq for a row is NULL then I need to use thelead_seq for the previous row (based on lead_action_date) for the sameoperator.This is what I came up with:SELECT LM.state, SUM(call_time)FROM Lead_Action_History LAHINNER JOIN Lead_Master LM ON (LM.lead_seq = LAH.lead_seq)OR (LAH.lead_seq IS NULLAND LM.lead_seq = (SELECT TOP 1LAH2.lead_seqFROMLead_Action_History LAH2WHERELAH2.operator_id = LAH.operator_idAND LAH2.lead_seqIS NOT NULLORDER BYLAH2.lead_action_date DESC))GROUP BY LM.stateThe problem is that Lead_Action_History has millions of records andany solution that I've found involves one or more subqueries on itwhich kills performance. I am going to look at using a covering indexwith the solution above, but I thought that someone here might haveanother way of doing this.I can't really change the structure, but I can play with the indexing.I would still be curious though how other people model this type oftemporal data in a way that makes it easy to work with.Thanks!-Tom.

Column Locked In Record Even Though No One Accessing Record

Mar 18, 2008



Hello. I have a database with a record that has two columns locked. descrip1 and descrip2. they are both nvarchar(max) columns. These are the only two columns of the record that remain locked. I am certain no user is accessing the record. I have even moved a backup of the database to my testing computer and the lock still exists. How do I remove the lock from these two columns on that particular record.

I can edit these two columns on other records. I have researched "Unlock" on MSDN but it doesn't seem to apply to t-sql. Any help would be greatly appreciated.

Thanks. Gary.
