[SQL SERVER 2000] Generic Table Exporter
Jun 28, 2007
Hello every body.
First of all sorry for my bad english but I'm french ;-)
My internship consits into making a generic table exporter (with a table list). Export into csv files.
I have tried 2 solutions :
1 - Create a DTS with a Dynamic Properties Task. The problem is I can easily change the destination file but when I change the table source I don't know how to remap the transformations between source and destination (do you see what I mean ?). Any idea ?
2 - Use the bcp command. Very simple but how to do when tables contains the separator caracter ? for example : If a table line is "toto" | "I am , very happy" --> the csv file will look like this : toto, I am , very happy --> problem to get back the data ( to much comma ).
Does someone has a solution ?
Last point is how to export the table structure ? For the moment, using the table structure, I generate an sql query which creates a table (I write this query in a file). Isn't there any "cleaner" solution ?
Thanks in advance and have a nice day all

I want to use ONE stored procedure to update/insert about 300 tables in a database. I hoped this code would work but it gives me an error:
ALTER PROCEDURE [dbo].[InsertRowsTick]
@tableName varchar,
@bid float,
@ask float,
@last float,
@volume int,
@dateTimed DateTime
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO tableName (
bid,
ask,
last,
volume,
dateTimed)
Values (
@bid,
@ask,
@last,
@volume,
@dateTimed)
END
When I (1) commented out @tableName parameter and (2) instead of INSERT INTO tableName wrote: INSERT INTO <realtableName> the code (C#) executed and the table was filled.
How can I use a generic table name as a parameter?
Thanks.

In general (I know.. lots of factors) but in general will adding more RAM to a SQL box help the performance? I'm working w/ 256MB right now, and deciding whether to add 256MB or 512MB? Any advice
Thanks and sorry so generic but this is a vendored app and they know of design issues but for now that can't be changed.

This Audit Trigger is Generic (i.e. non-"Table Specific") attach it to any tabel and it should work. Be sure and create the 'Audit' table first though.
The following code write audit entries to a Table called
'Audit'
with columns
'ActionType' //varchar
'TableName' //varchar
'PK' //varchar
'FieldName' //varchar
'OldValue' //varchar
'NewValue' //varchar
'ChangeDateTime' //datetime

The trick was getting the Table Name and the Primary Key Columns.
I hope this code is found useful.

Hi guys
I have a simple problem:
I want to be able to query with a start date(@start) and then calculate 1 year from there. I figured since the date is of type integer just add 364 and it will give me the day before 1 year.
So if its 1998-05-01, Id get 1999-04-31.
Code:
DECLARE @FinStart DATETIME
DECLARE @FinEndDATETIME
SET @FinStart = '1998-05-01' --is of type int .:. +365 is adding 1 year
SET @FinEnd = @FinStart + 364
SELECT @FinStart
SELECT @FinEnd
Problem, this doesnt cater for leap years.
Any suggestions?
The help is always appreciated!

Here's the scenario:
whenever a change (insert/update/delete) has occured in any of the tables, it needs to be logged by adding the changed table's name, and changed columns' names (if any) into the special ChangeLog table.
So, is it possible for me to write a generic trigger that would get the name of the table it just executed upon and names of every column affected by the UPDATE and then insert those into the Log table?
If this is not possible, how do you suggest it should be done?
I'm familiar with standard SQL but T-SQL is completely new to me, so please bear with me if my question makes no sense...
Thanks!

Hello,
Can someone please guide me to online resources or books on how to design generic database? I mean, I can have a "Record" that can have a set of fixed fields like: ID, Title, CreatedOn, etc ... and I can add as many properties I want to that record in a vertical way.
Then based on the generic tables present, I can fit in the same table, a Record for Customer, a Record for House, a Record for Order. All share the same set of Fields, but each has its own set of proeprties.
This way, I design my database once, and customize it to fit any type of applications I need.
Is there something like that or just dreaming?
thanks

I have 24 lookup tables that contain the same columns (e.g. Rec_Id (identity field), Code, Desc) and I need to build an interface for each of these tables with Create, Update, and Delete capabilities.
I would like to create three stored procedures (create, update, delete) that would perform the task for any of the lookup tables.
For example, table AGENCY has three fields (Agency_id (identity field), Agency_Code, Agency_Desc) and I need to add a new record to AGENCY. I would like to call a stored procedure that would take the parameters @tablename, @code, @desc, and then create a new record in the table specified by @tablename.
I could then use a single "create" stored procedure for all of the lookup tables when adding a new record, rather than creating a separate "create" stored proc for each of my lookup tables.
Any help would be greatly appreciated!

I am attempting to create a generic stored procedure in SQL Server 6.5 which returns a record count of a specific table passed in as a parameter. The stored procedure looks like this"
CREATE PROCEDURE asp_GetRecordCount
@tablename varchar(30), @recordcount integer OUTPUT
AS
/* Generic stored procedure which returns
number of records in a table.
*/
SELECT @recordcount = COUNT(*) FROM @tablename
RETURN
GO
The problem is that when I save the stored procedure, SQL Server balks at the FROM @tablename entry. Any suggestions? Thanks.

Hi,
My current project requires me to convert a mysql based software to a more generic one. I started by designing separate db class files and separated the lower level connection queries from the business logic. By doing this, I now have mssql.class, mysql.class, sqllite.class etc..
But am not sure how to handle sql functions in queries. For instance, one of my queries need the use of a date function to add minutes to a db field.
In mysql, I accomplish this using
dbfield+interval '$arg' minute between date1 and date1
But in mssql I cannot use this type of query. It seems I'll have to use date_add() function. How do I handle this situation?
My frontend scripting language is php
Thanks d'advance

I have a bunch of tables for my basketball club's d/b. I want to be able to interrogate them to build a web page showing player stats. For example, I want a table showing the top 5 scorers, top 5 3-point scorers, etc. What's got me foxed is how to join it all up and then sort it into the top 5 order. The main tables in question are T_Member, T_Fixture, T_Season and T_FixtureTeam:
T_Member:
MemberNo, FirstName, LastName, (etc)
T_Fixture:
FixtureNo, SeasonNo, MatchDate, (etc)
T_Season:
SeasoNo, SeasonDescription, SeasonStartDate, SeasonEndDate, CurrentSeason
T_FixtureTeam:
FixtureNo, MemberNo, 2Points, 3Points,Fouls,FreeShotAttempts,FreeShotsHit,Assists
Where you see the same field name, that field data is common for all tables that it appears in. In other words, for example, the T_FixtureTeam 'FixtureNo' and 'MemberNo' fields are made up of 'T_Fixture.FixtureNo' and 'T_Member.MemberNo' respectively.
Ready?
The user will select a season at the top of the page (although there's a default to the current season (CurrentSeason is a Boolean field). The query needs to:
- Find all fixtures in that season
- Find all members who played in those fixtures
- Find the top 5 3-point scorers (or whatever stat I'm gathering) for those matches
- Sort the resulting data
I figure I need a JOIN on MemberNo but, as I say, the rest of it has my head spinning.
TIA

Hi,
This is really a Visual Studio 2005 Report Designer problem but I didn't see a good place to post this question in the Visual Studion forum.
On some reports when looking at the Data tab the Generic Query Designer is disabled. Anybody know why? The report runs. Other reports have it enabled.
I am using Visual Studio 2005 sp1.

Here is my situation. I have a fairly large query that I am working on in visual studio (data tab). I am at the point where the program will NOT let me type (add SQL code) anymore. I found that clicking the Generic Query Designer (turning the query builder on) button switches the format then allows me to add more code. Well, this solves the running out of room issue, BUT now it does something to my code and it will not process it. Prior to clicking the Generic Query Designer button, everything worked w/ no errors. I did not change anything, but simply pressed the Generic Query Designer button (turning the query builder on) and now it dose not work now. Just for kicks, I have pasted my working origional code into SSMS, added code and it executed just fine in SSMS. But then I pasted back into visual studio and it gave me the same errors?
Has anyone experienced this? Is there a maximum for lines of code? Why does the Generic Query Designer (having query builder on) change my code? All comments are welcome!

An SSIS package to transfer data from a DB instance on SQL Server 2005 to SQL Server 2000 is extremely slow. The package uses an OLEDB Source to OLEDB Destination for data transfer which is basically one table from sql server 2005 to sql server 2000. The job takes 5 minutes to transfer about 400 rows at night when there is very little activity on the server. During the day the job almost always times out.
On SQL Server 200 instances the job ran in minutes in the old 2000 package.
Is there an alternative to this. Tranfer Objects task does not work as there is apparently a defect according to Microsoft. Please let me know if there is any other option other than using a Execute 2000 package task or using an ActiveX Script to read records from one source and to insert them into the destination source, which I am not certain how long it might take and how viable will that be?
Any inputs will be much appreciated.
Thanks,
MShah

sql server 2000I am currently maintaining a table that contains 30 Million+ records,30 columns, and 11 indexes and will double within the next six mouths.The application that accesses this table, mainly for read onlypurposes, runs without any problems. We have begun using Crystalreports and are now having problems. When we create reports thataccesses the large table our server has significant performance dip.The application begins to time out and the reports take a very longtime, even with simple selects on indexed field.I have began looking into partitioning the large table on its key fieldand creating a partition view. But from what I have read this willonly help if we key on the partitioned field. And all other searcheswill actually take a little longer.Archiving old data is not an option. All the data is being usedAny suggestions will be appreciated. Thanks in advance.Rick
