I have to create a history of tables. Therefore I must know the previous structure of the table. I have to document the changes of the structures of the tables.
Is there a solution for the version 2000?
For my company, we have made it a standard to create history tables and triggers for the majority of our production tables. I recently grew tired of consistently spending the time needed to create these tables and triggers so I invested some time in creating a script that would auto generate these.
We recently launched a project which required nearly 100 history tables & triggers to be created. This would have normally taken a good day or two to complete. However, with this script it took a near 10 seconds. Here are some details about the script.
The code below creates a stored procedure that receives two input parameters (@TableName & @CreateTrigger) and performs the following actions:
1) Queries system tables to retrieve table schema for @TableName parameter
2) Creates a History table ("History_" + @TableName) to mimic the original table, plus includes additional history columns.
3) If @CreateTrigger = 'Y' then it creates an Update/Delete trigger on the @TableName table, which is used to populate the History table.

Hi
I have a table called my_history that has columns like this
column_name , old_value, new_value, key, date
bankaccount 30 50 1 01-Apr-2008
bankbalance 10 14 2 04-Apr-2008
and so on............
The history table is populated using triggers
The main table called my has a structure like
bankaccount bankbalance bankname name address key
50 50 xyz abc ford 1
30 14 abc xyz east 2
Now using this information can i reconstruct the records in my table before the update happened ?
I am finding it very difficult to do this is there a way to do this in t-sql ?
The problem is my_history table where the column_name keeps on varrying

Hi,
To programmatically invoke a subscription we can use -
exec ReportServer..AddEvent 'TimedSubscription', '575F96C6-A1BD-49FD-9C2F-934FC9658780'
How can we programmatically cause a Manual Report History Snapshot to be created.
I know it can be done using the Webservice. How would we do it using the ReportServer stored procedures. Which SP/SP's can we call. With what parameters.
TIA,
Sam.
Hi,
I want to backup an important table every week in creating some history tables.
I would like to create a Dts job or script to create every week a table with the day and month in its name. ( like : [important_table_09-07] , [important_table_09-14],... )
Any idea ?
Thanks.
Hi,

When creating history tables that are appended to whenever a record isupdated, should one append the corresponding child table records to theirhistory tables at the same time (so as to have a complete set for eachedit); or should one append the child tables only when those particulartables are edited? I have been doing the latter, but I thought I'd ask forothers' opinions.Thanks!Neil

How frequently will the history tables get deleted in Merge Replication and Transactional Replication with updatable subscriptions??
When transactional replication with updatable subscriptions is running in the continuous mode, will the history tables get deleted frequently??
Parameters :
Version : SQL Server 2005 SP1
Mode : Continuous running mode
Subscription type : Pull (for transactional)

I've got a large and growing database in SQL Server 7.0. I'd like to utilize a monthly stored procedure that will search various tables for records that are older than 3 months and copy this data out to corresponding history tables. Typically, most production queries are run only on the new data, but occasionally (like at year-end, for example), we will need to run some queries on data extending back 12 months -- that is, on data in the production tables AND in the history tables. Notwithstanding the fact that I've never done stored procedures*, I would like to know if it is possible to run a query that can search for data in both production and history tables at the same time. I know this sounds like a stupid question, but I read somewhere that doing this qould require some kind of Joining function that is complex...?
Thanks,
Whill96205
* Also, any good resources I could use for developing stored procedures?
We have a need to report on historical data when none exists in the database.
Create a tabular report rdl that is run on a regular schedule. This report run is saved as an Excel sheet that overwrites the previous run, which has the same name.
Report is designed to use two data sources--the database and and the previously run Excel sheet. The data is "merged" using the Lookup function thereby creating a new report that includes the history needed.

Hello all,
Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.
Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.
What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1
Please help :-D

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.

flowid and stepid for both tables match; meaning that if i found a record in task with a certain taskid, i could query stepdefinition with the same flowid and stepid to find the steptype.
well, i wanna do it the other way around. I query stepdefinition to find a list of flowids and stepids for a specific steptype.
select flowid, stepid from stepdefinition where steptype = -3

Hi, I have a users table in my SQL Server database. Now, I am looking to create a table (or multiple tables) to allow users to post their weekly events, meetings, activities, and accomplishments to the database. Each Monday morning, each user will enter their new schedule for that week and the previous week's entry will be archived in the database. My question is: what would make more sense? Should I create one big table that would have the following columns:
- Week Number (the current week number in the year)
- User ID
- Events
- Meetings
- Activities
- Accomplishments
And each user would have one row in the database per week.
OR should I create 4 separate tables named Events, Meetings, Activities, Accomplishments. Each of these tables would have the following columns: (for instance, the Events table would contain:)
- eventID (auto incremented number)
- userID
- weekNumber
- event_description
Each time a user adds a new event to their schedule, a new row in the Events table is created. Each time a user adds a new accomplishment, a new row in the Accomplishments table is created. etc., etc.
Which approach seems to make more sense and would be easier to maintain? Also, which one would conserve database space better and result in faster querying.
Thanks, Dave
I'm attempting to use SQL statement to create tables within a new database, and I'm somewhat lacking in experience for this. Normally I'd simply create them through the GUI, but I want to get the hang of DDL statements.
I have written what I think are scripts to create one table with a primary key, create a unique index on it, and then create another table with a primary key and constrain two columns in the second table to the non-primary unique index in the first.
Code:
Use SKUTracking
CREATE TABLE
SKUTracking.dbo.tblOraUnits

Im trying to bring together two tables into one, but they're records dont always match, so im getting akward returned records. So now i want to combine the fields i need from these two tables to create a new one. How would that be coded.
I want to

[Customer_Bill_Customer_No],
[Customer_Bill_Customer_No],
[Sales_Header_Order_DateTime],
[Sales_Header_Your_Reference]

now , how would i do that?
I'm trying to create two tables, Admins and SecurityGroups, I want to have the ability to assign a security group to an admin so that I don't have to specify all the rights individually to every admin. So, I have the securityGroupID in the Admins table and I reference the SecurityGroups table for data integrity. On the other hand, for audit purposes, I also want to record which admin created the security group so I have the AdminID in the SecurityGroups table and I reference the Admins table for data integrity. Of course when I try to create any of those tables I get an error message that the other table doesn't exist. I wonder if this can be done without having to remove the references constraint from one of the tables and then using alter table. Here's an example below to make it clearer:
CREATE TABLE Admins
(
AdminID INT NOT NULL PRIMARY KEY,
SecurityGroup NULL REFERENCES SecurityGroups (SecurityGroupID)
)
CREATE TABLE SecurityGroups
(
SecurityGroupID INT NOT NULL PRIMARY KEY,
CreatedBy INT NOT NULL REFERENCES Admins (AdminID)
)
Any suggestions are highly appreciated...
I'm currently developing an RDF application which need to handle lots of datatypes. But I want to use SQL-Servers capabilities for efficient querying and sorting. Therefore, I've wanted to create a Main Table which stores a Reference to the Table where the Data is stored. The Data itself should get stored in a Datatype-specific Table.
The Typed Table might get created by something like:
public void CreateTypedLiterals(Type type)
{
String sql = String.Format(
"CREATE TABLE [Literals_{1}] (" +
"ID int DISTINCT NOT NULL, Value {1})",
// BUG: does not work
// WARNING: introduces a potential sql-injection problem
type.ToString()
);
...
As you can see on the statements this solution makes many troubles. So I've wanted to implement it in a more fine way using a DataTable:
[SqlProcedure]
public void CreateTypedLiterals(Type type)
{
DataTable TypedLiterals =
new DataTable(
String.Format("Literals_{0}", type.ToString()));
TypedLiterals.Columns.Add(
"ID", typeof(int), "DISTINCT NOT NULL");
TypedLiterals.Columns.Add("Value", type);
...
But I have totally no Idea how to fetch this result into the existing Database. It might be cool to simply access the Database as it would be a .NET Dataset in the form:
using(Microsoft.SqlServer.Server)
{
CurrentDatabase.Tables.Add(TypedLiterals);
}
But this is afaik not possible. Has anybody an idea how to solve this issure?

I want to do this on all my tables I need to pull from and create on my sql ce db
Hi, I am trying to create a create for two table A and table B which have no relationship each time. For TableA, there are 3 columns like ID, APoints1, APoint2. For Table B, there are also 3 columns as ID, Qty, BPoints. There is no internal relationship for these two tables. But there may be same ID inside A and B for some records. Now I want to create a datagrid for displaying the information as :
ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID
Please Notice that I can't use directly SQL script as following from table A and table B because there is no relationship for Table A and Table B, otherwise the recult set would be wrong:
Select A.ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID group by A.ID
May I know is there solution for it?
Thank you very much!
