Table4 - primary key = SourceServiceNo (Foreign Key from Table1), MemberServiceNo(Foreign Key from Table1)
what I need to do is copy all records from Table1 where CampaignNo = @CampaignNo and insert them into table1, this I can do easily but I will generate a new ServiceNo for each one and associated a new CampaigNo which is fine.
The problem comes in that I need to also copy the contents of Table2 = Table3 for all ServiceNos that have been copied from Table1 but insert the new Guid that will have been created when copying the rows in Table1
This is further compounded when I need to do the same to Table4 but this time I need to insert the newid's for SourceServiceNo and the related MemberServiceNo which all would have changed.
I haven't the first clue where to start with this task, do I need to use temporary tables, cursors? any help gratefully received, even if it's a pointer to the most efficient approach.
Hey everyone, I am beggining in SQL and the .NET framework and have been running into some problems trying to design a relational database. I am completely new to it so I bought a book that was recommended in this Forum called "Handbook of Relational Database Design" and it has been pretty usefull so far. RIght now I am trying to make the Logical Data Model before I make the Relational Data Model. The problem that I am having right now is creating a table that is a derivation from another table. For example, in the book they have a table called Property, and then two other tables called MountainProperty and BeachProperty. MountainProperty and BeachProperty are a type (relationship here) of a property. So basically Property will hold some data in a table, and then MountainProperty and BeachProperty will extend that property to contain more specific data. This is very similar to what I want to do. However I am having a problem understanding how an instance (or row) in Property, will have a link (foreign key) to a piece of data that is in Mountain or BeachProperty. I understand the foreign key in Mountain and BeachProperty and how they will link back to their "parent". But how will Property know its children, where is the link for that, how can one make a link to that. You could make a column with a foreign key, but which table would it point to, can one column point to mulitple tables? That doesn't make very much sense to me. Basically what I am trying to say is that a row in the Property table can be multiple types, and these types will store more additional data about that row. How can I link to that data from that row in the Table Property. I am terribly sorry if this is confusing or if it is so appartently easy for you, but this is the first time that I have ever tried to make a relational database and I am really struggling on seeing how to organize these tables properly. Thank yor for your time. Jeremy
I created my database on a remote server. It now has lots of tables and stored procedures When I created it, the server created a schema named for me, the user, so all my tables and stored procedures are named like johndoe.tablename. I would like to rename the schema to something less personal more professional. Can it be as simple as "ALTER SCHEMA johndoe RENAME professional"? Also, I would like to create a local copy of the databse, so I can develop offline, without the 2 second delay. SQL Server Management Studio Express lets me generate scripts, which I have been using to make backups. Can I use the script file to recreate the database on my local machine?
I have a couple tables that I am exporting data from.
I have one table (call it TABLE1) that contains abbreviations instead of actual words.
For example instead of having the full word "New York City", the column would just contain "NYC".
In another table (call it TABLE2) it has all the abbreviations and the actual words.
So in TABLE2 one column name is FieldName, another Abbreviation and another is Value.
So on a web site, to display that actual name I do something like this
Code:
SELECT CityBoxlabel AS City FROM TABLE1 INNER JOIN TABLE 2 AS CityBox ON ISNULL(TABLE1.City, 'NYC') = CityBox.[Value] WHERE CityBox.FieldName = 'City'
This is working great except that some of these columns contain more than one abbreviation such as "NYC,WDC" which would stand for "New York City" and "Washington DC" The items that have more than one abbreviation are not being pulled across because my query is looking for an "NYC,WDC" in TABLE2 to INNER JOIN on but it won't be in there. But "NYC" and "WDC" by themselves are in there.
I tried messing with the INNER JOIN statement by saying something like TABLE2 AS CityBox ON ISNULL(TABLE1.City, 'NYC') IN CityBox.[Value] INNER JOIN
But it wasn't allowing that. I can write a program to do this, but I would rather keep it in T-SQL.
Hope this wasn't too confusing! Any help is greatly appreciated!!
I'm attempting to create a complex query and i'm not sure exactly how i need to tackle I have a series of tables:
[tblEmployee]
empID
empName
deptID
jobtID
[tblDept]
deptID
deptNum
deptName
[tblJobTitle]
jobtID
jobtNam
[tblTrainng]
trnID
trnName
[tblTrnRev]
trnrevID
trnID
trnrevRev
trnrevDate
[tblEduJob]
ejID
jobtID
trnID
[tblEducation]
eduD
empID
trnrvID
eduDate
The jist of this database is for storage of training. The Training table is used for storing a list of training classes. The TrnRev links and shows each time the training was updated. The EduJob table links each Job title (position) in the company to each trainng class that position should be trained on. The Education table links each employee to which revision of a class they have attended.
What i need to do is create a query that for each employee, based on their job title, wil show what classes they are required to be trained on. I want the query to return the employee, the training, the latest revision of that class, and then show if a) the person's trainig is current for that revision, b) the person has been trained on that topic but not the latest revision, or c) they've had no training at all on that topic.
The queary I need is to display the result in this form. must be like this
docIDdocName Avaragerating 1aaa3 2bbb3 3ccc0
NOTE : For getting the average I used this queary “SELECT SUM(rating) As RatingSum, COUNT(*) As RatingCount FROM tbl_Rating WHERE tbl_rating.docID = tbl_documents.docID”
do you have a general rule of thumb for breaking a complex query into temp tables? For someone who is not a sql specialist, a query with more than a few table joins can be complex. So a query with 10+ table joins can be overwhelming for someone who is not a sql specialist.
One strategy is to break a problem into pieces so to speak by grouping together closely related tables into temp tables and then joining those temp tables together. This simplifies complex SQL and although not as performant as one big query it's much easier to understand. So do you have a general rule of thumb as far as a threshold for the number of joins you include in a query before you break the query into temp tables?
Hello,I am creating a new database and I was advised to use Sequential Guids.I was reading some information and, as far as I understood, I can use NEWSEQUENTIALID. This can be used when I have a uniqueidentifier column as the key of a clustered index to avoid fragmentation during insert. Ok, so I use NEWSEQUENTIALID instead of NEWID.But I will use LINQ most of the time instead of Stored Procedures.So can I specify in my tables scripts to use Sequential Guids when, for example, a record is created? And am I right when using Sequential Guids?Here is a part of my code:-- Blogs ... create table dbo.Blogs ( BlogID uniqueidentifier not null constraint PK_Blog primary key clustered, Title nvarchar(400) null, Description nvarchar(2000) null, CreatedDate datetime null )
-- Posts ... create table dbo.Posts ( PostID uniqueidentifier not null constraint PK_Post primary key clustered, BlogID uniqueidentifier not null, AuthorID uniqueidentifier not null, Title nchar(1000) null, Body nvarchar(max) null, UpdatedDate datetime not null, IsPublished bit not null, constraint FK_Posts_Blogs foreign key(BlogID) references dbo.Blogs(BlogID) on delete cascade, constraint FK_Posts_Users foreign key(AuthorID) references dbo.Users(UserID) on delete cascade Thanks,Miguel
We're trying to set a new standard at my office, of using GUIDs as database ID fields - all new tables in all databases will have a GUID as the ID field, using the UniqueIdentifier data type.
The problem that we are running into, is that different applications interpret the UniqueIdentifier data type differently - ADO 2.x interprets it with the opening and closing { } braces. ADO.NET does not include the { and } in the GUID structure, SQL Server Query Analyzer does not include the { } braces, and SQL Server Enterprise Manage does include the { }
The problem with this is in two parts: 1) VB6 does not have a GUID structure or data type, so we are treating GUIDs as strings... but VB6 doesn't recognize "{012345678-abcd-ef01-2345-6789abcd}" and "012345678-abcd-ef01-2345-6789abcd" as the same string 2) when sending a URL link through an email, the { } braces break the link - in all email applications that we have tested. This include Groupwise 6, Groupwise 6.5, IPSwitch Web IMail, Outlook 2000, and Outlook Express (IE 6).
We're becoming very frustrated with the problems at hand, and need to know how others have worked around these problems. Please respond with any kind of advice or any real life situations where you have encountered this and found a solution, etc.
I have web forms with about 10-15 optional search parameters (fields) for a give table. Each item (textbox) in the form is treated as an AND condition.
Right now I build complex WHERE clauses based on wheather data is present in a textbox and AND each one in the clause. Also, if a particular field is "match any word", i get a ANDed set of OR's. As you can imagine, the WHERE clause gets quite large.
I build clauses like this (i.e., 4 fields shown):
SELECT * from tableName WHERE (aaa like '%data') AND (bbb = 'data') AND (ccc like 'data%') AND ( (xxx like '%data') OR (yyy like '%data%') )
My question is, are stored procedures better for building such dynamic SQL clauses? I may have one field or all fifteen. I've written generic code for building the clauses, but I don't know much about stored procedures and am wondering if I'm making this more difficult on myself.
I've been thinking about using GUIDs as primary keys within my application. One problem I have with this approach is that GUIDs generated with NEWID() are not sequential, and this can have a huge impact on insertion performance due to fragmented indexes. It would seem that NEWSEQUENTIALID() solves this issue, however it doesn't seem very practical to use this on SQL Server Mobile. With SQL Server, you can specify an OUTPUT clause for an INSERT statement, and using this, determine what the last inserted GUID was. There doesn't seem to be such an option in SQL Server Mobile, so how can I get the last generated GUID so that I can attach children records to my parent record? It's been suggested that you could use the MAX() function to get the latest GUID, but there is a problem with this approach - NEWSEQUENTIALID() guarantees that the GUIDs generated will be sequential for the machine generating them, but makes no guarantees about how this will fit in with GUIDs generated by other machines. It is entirely possible that GUIDs generated by a different machine will be larger than the latest one generated on the current machine, so using MAX() to determine the latest value doesn't seem like a valid option to me.
Does anybody have any ideas on tackling this problem? Any thoughts on the suitability of using GUIDs as the primary key for SQL Server Mobile devices in general?
Am I looking at a potential bug here or do I not understand the feature properly? I have an ExecuteSQL task that inserts into a table for logging and includes the System::PackageID as one of the values. It's stored in my table as a uniqueidentifier. When I set the output variable in Parameter Mappings tab of the Execute SQL task to VarChar, all works great. WHen I set it to GUID as the data type in that tab, it outputs a different GUID than the actual System::PackageID variable.
Are Guids good or bad? I've spoken to people who hate them in databases, but the db's I'm using right now all use them, so there must be *some* people out there who like them. I'm interested to know what other people think.
I have a table that I am basically reduplicating a couple of times for each part of this database that I want to create.Each table basically has the same data: The tables will be called motherTable, fatherTable, sonTable, daughterTable and so on.I am pretty much using the following in each column: UserID, MotherID(or FatherID or SonID, etc., etc. and so on for each unique table), FirstName, LastName, MiddleName, BirthPlace, Photo, Age.I don't see an option to copy a table and just modify the second ID part and rename that table accordingly.How can I make this an easier way of creating these similar tables without retyping all these columns over and over again?Thanks in advance.
Hi,I was just wondering... Is there any built-in function in MS SQL, which willallow me to do rows' "capitalisation"?Lets say that in database.table.name I've got:"FOO BAR LTD.", which I want to change to "Foo Bar Ltd.""Foo bar LTD.", which I want to be "Foo Bar Ltd.".Is there any way of doing this or do I have to read it from database, changein some script, and then insert it back into the table?Hope it's all clear ;-)Thank you,Martin
I need gurus input on the pros and cons of Seeded(int) Identity colums vs. UniqueIdentifier(GUIDs) columns for my db design.
As I understand it, merging the data of 2 independent db's both using IDENTITY columns would be very hairy because of the possibility of overlap. GUIDs are much more likely to be unique across different servers.
What I'd like to hear from others are the other pros and cons of the situation. I of course understand the performance hit suffered at the hands of the GUID.

I'm trying to convert this statement to use left outer joins so it will be 2005 compatible.
select convert(varchar(8),a.order_no), a.order_ext, a.line_no, c.part_no, a.order_seq, a.customer_code, b.date_shipped, 0, a.seq_descript from fm_orderline a, orders b, ord_list c, fm_ordhist d where c.order_no = a.order_no and c.order_ext = a.order_ext and c.line_no = a.line_no and c.order_no *= d.order_no and c.order_ext *= d.order_ext and c.line_no *= d.line_no and b.order_no = c.order_no and b.ext = c.order_ext and d.line_no <> 999 and c.status = 'T' group by d.order_no, convert(varchar(8),a.order_no), a.order_ext, a.line_no, c.part_no, a.order_seq, a.customer_code, b.date_shipped, a.seq_descript having d.order_no is null
I've tried this: select convert(varchar(8),a.order_no) as order_no, a.order_ext, a.line_no, c.part_no, a.order_seq, a.customer_code, b.date_shipped, 0, a.seq_descript from fm_orderline a, orders b, ord_list c left outer join fm_ordhist AS d on (c.order_no = d.order_no) left outer join fm_ordhist AS d2 ON (c.order_ext = d2.order_ext) left outer join fm_ordhist AS d3 ON (c.line_no = d3.line_no) where c.order_no = a.order_no and c.order_ext = a.order_ext and c.line_no = a.line_no and b.order_no = c.order_no and b.ext = c.order_ext and d.line_no <> 999 and c.status = 'T'
And various derivations of it(adding d2.line_no <> 999 and d3.line_no <> 999 to the where clause.) But it came up with different results than what I received when it was a *= query.

i have a database with 300 tables. All the data types of the fields of my tables are custom. Ex. IFGint:int and stuff like that.
I want to know how can i through a stored procedure, change in batch mode all the fields of my tables. I don't want to modify by hand everytable. It's a lot of work and i think that maybe there might be a way for this programatically.
I have two databases and want to copy tables (with table data) and stored procedures from one database to another.both databases have the same name (so management studio is not letting me have both up)....what should I do?thanks.
What is the easiest way for me to copy my database tables so that I could use the copy as a template to work on for setting primary keys, and normalizing the data?
A question from a beginner. Is there a simple command to create a copy of at table with its original attributes. I would like to take a table for a year and copy it to an archive file with the year appended to the name, i.e. myfile copied to myfile02
Hi I have a DB2 database server.It has 2000+ tables...And I have a MS SQL database server.It has got the same tables.With same schema... I want to take all of that tables datas to MS Sql database's tables.... I try to use DTS Import Data Wİzard but it gace an erro which is Unknown Error!!!
Now; I try to make a DTS which is capable with doing this mission... I want to create one DTC package and the source table and destination table names will be changed dynamically...Probably i should use ActiveX Task or Dynamic PropertTask... Despite i have searched from net very much i couldnt find any helpfull article or sample for 3 days...I have also checked this one; http://www.sqldts.com/default.aspx?246
But it hasnt helped me too..
I really wish thatsomebody can help me... Thank u all
I want to copy from DB certain tables to an other DB. How can I do that with SQL Server 2005. I would prefer an SQL string solution instead of buttonclicking solution.
Apologies if this has been raised in the past, but 6 hours of web searching today hasn't turned up anything!
I'd like to use the Slowly Changing Dimension (SCD) Wizard to keep track of tables in my relational database. This means 200+ tables. I don't want to step through the UI Wizard for each table. Ideally I'd like to be able to create the SCD transformation in code, but I can find no good examples for doing this. The MSDN examples here are too brief and don't allow me to expand out to the level I need.
As in any database, columns come and (very rarely, go), and having a programmatic solution to this would mean that I could be flexible and cope with these situations.
So, my question is: Has anyone implemented SCD functionality in code, or have any code examples that do this, that I might learn from. Or, any tips/pointers if I'm barking up totally the wrong tree.
