when table purge

I have set up code that whenever I user returns the site a new cookie is created(persistent) and the token
is stored in the corresponding table in the database.

Suppose that someone comes 2-3 times/day in the site,multiply that with number of registered users and
the tables gets written many times,becoming large quickly. often should I erase table rows you think
Do you think-for example- that from the moment I create a token to the table I should delete the previous one-belonging to the same user obviously

Is there a rule of thumb in this

As a second though, maybe I just need update the token in the place of the previous one

Creating inter-table relationships using Primary Keys/Foreign Keys Problem   (150 Views)
again, I'm going through my tables and rewriting them so that I can create relationship-based constraints and create foreign keys among my tables. I didn't have a problem with a few of the tables but I seem to have come across a slightly confusing hiccup. Here's the query for my Classes table: Code: CREATE TABLE Classes ( class_id INT IDENTITY PRIMARY KEY NOT NULL, teacher_id INT NOT NULL, class_title VARCHAR(50) NOT NULL, class_grade SMALLINT NOT NULL DEFAULT 6, class_tardies SMALLINT NOT NULL DEFAULT 0, class_absences SMALLINT NOT NULL DEFAULT 0, CONSTRAINT Teacher_instructs_ClassFKIndex1 FOREIGN KEY (teacher_id) REFERENCES Users (user_id) ) This statement runs without problems and I Create the relationship with my Users table just fine, having renamed it to teacher_id. I have a 1:n relationship between users and tables AND an n:m relationship because a user can be a student or a teacher, the difference is one field, user_type, which denotes what type of user a person is. In any case, the relationship that's 1:n from users to classes is that of the teacher instructing the class. The problem exists when I run my query for the intermediary table between the class and the gradebook: Code: CREATE TABLE Classes_have_Grades ( class_id INT PRIMARY KEY NOT NULL, teacher_id INT NOT NULL, grade_id INT NOT NULL, CONSTRAINT Grades_for_ClassesFKIndex1 FOREIGN KEY (grade_id) REFERENCES Grades (grade_id), CONSTRAINT Classes_have_gradesFKIndex2 FOREIGN KEY (class_id, teacher_id) REFERENCES Classes (class_id, teacher_id) ) Query Analyzer spits out: Quote: Originally Posted by Query Analyzer There are no primary or candidate keys in the referenced table 'Classes' that match the referencing column list in the foreign key 'Classes_have_gradesFKIndex2'. Now, I know in SQL Server 2000 you can only have one primary key. Does that mean I can have a multi-columned Primary key (which is in fact what I would like) or does that mean that just one field can be a primary key and that a table can have only the one primary key In addition, what is a "candidate" key Will making the other fields "Candidate" keys solve my problem Thank you for your assistance.

Issues importing a text file (tab delimited) to a SQL table   (175 Views)
I have a text file I am trying to import to a table. This text file is in a tab delimited format. I am using DTS to import the data to a new table I made. The fields are varchar and are set to allow nulls & allow 8,000 characters per field. The error I am getting is that the data exceeds the allowed amount (or something like that) in col4. Now I have checked everything in column 4 and nothing exceeds 5,000 spaces/characters combined. I have checked the entire sheet (in excel) for that fact, and there is not one single column/row/cell that exceeds 5,000 spaces/characters combined. What the heck could be causing SQL to tell me I am trying to import too much data in one column when there is nothing that even comes close to 8,000 characters & spaces combined

Combining info from two tables?   (179 Views)
, I'm having some problems trying to access two tables in a SQL database at the same time and making some results out of them. Let me explain further: the first table has some information in that I'm going to be doing a select query on and reading out, but one of the columns in this table is a set of codes, the second table contains the codes in one column and their meanings in the other. So I want to bring back the information from the first table and then select the information for the codes shown from the second table and print their meanings alongside the information from the first table. Could anyone help me out in figuring out how my SQL in the ASP page for this would be written Sorry if this is a little confusing but im having a hard time visualising how to do this.
Help with MS SQL Server - updating data from 2 tables   (169 Views)
Hi all, Please forgive me, but I'm new to MS SQL Server and I have few questions. First of all I'd like to know if there is a way to update one table with the data from another. Let's say I have 2 tables. TableA table contains the voucher numbers; TableB table contains the image numbers. Is there a way to merge Voucher numbers from TableA table to Image numbers in TableB table if we assume that there is a primary key Voucher Number in both tables If yes- what would be the query structure for that Please forgive me if you think that this question is silly, I have to say I'm not just new to SQL I'm VERY new to it Thank you in advance.
problem w/ linked table permissions   (168 Views)
This question involves SQL server as well as Access, so I hope that someone can follow. I'm trying to give someone read and write access to a table in SQL server through a linked table scenario in Access. I set up a new user account with datareader and datawriter permissions and made sure it went into the particular table as well. I also re-created the DSN on the user's local machine using this new login information. However, each time you open up the table after logging in using this info and try to edit a field, it gives a "Write Conflict" error and gives three choices: Save Changes, Copy to Clipboard, Drop Changes and of course, Save Changes is disabled. We also tried logging in using the db admin account and it won't work. Anyone have similar experiences with this If so, is there a work-around so that you can edit data through Access

Migrate Sybase DB to MS SQL... datetime problem.   (174 Views)
I have a Sybase server with my source data. I have a MS SQL 2000 server for my destination. Trying to migrate all the data from the Sybase instance over to the SQL instance... not really all the data, just the tables that have a rowcount above '0'. I don't care about PK/FK relationships, constraints, triggers or stored procs. I came up with the following script, using the linked server features of SQL2000. Code: declare tablecursor scroll cursor for select name from openquery(LINKEDSERV, 'select name from sysobjects where type= ''U'' and uid = 1 order by name') open tablecursor declare @tablename varchar(50) declare @sql nvarchar(800) fetch first from tablecursor into @tablename while @@fetch_status = 0 begin set @sql = N' IF (select * from openquery(LINKEDSERV, ''select count(*) from ' + @tablename + ''')) > 0 BEGIN select * into TargetDB.dbo.' + @tablename + N' from openquery(LINKEDSERV, ''select * from ' + @tablename + ''') END' -- select @sql exec sp_executesql @sql fetch next from tablecursor into @tablename end close tablecursor deallocate tablecursor But, about part way through I get an error. Server: Msg 8114, Level 16, State 10, Line 3 Error converting data type DBTYPE_DBDATE to datetime. Seems that implicit conversion is not working for the Sybase datetime datatype and the SQL2000 datetime datatype. I don't want to write an import for each table... I have about 100 total tables to target. Any ideas Can DTS help in this case, even though this source server is not an MS server I want the whole database, and I don't want to write a construct for each table.

Dead-Man switch for stored procedure   (151 Views)
I probably should know the answer to this, but it is eluding me. I have a stored procedure called Morning_Refresh something like this: CREATE PROCEDURE Morning_Refresh AS -- create snapshot DELETE FROM Static1; INSERT INTO Static1 Select * From Table1; -- updates in system UPDATE TABLE2 SET X = (Select Y FROM Table1); UPDATE TABLE3 SET X = 'C' WHERE ID NOT IN (SELECT ID FROM TABLE1); And so forth. Now, all is well, there is a real chance that that Table1 that I am updating everything with could be bad. I want to add some sort of sanity check to the procedure, so that if Table1 does not meet certain requirement, NOTHING gets changed. For now, the check will simply be that there in fact are records in Table1. How can I modify the stored procedure so that it will do nothing if there are no records in Table1
SQL SP Validation   (160 Views)
I have project where I am building an ASP.NET Internal Website that will run Updates, Selects, and Inserts on a SQL Server 2005 Database. There will be a series of forms that will call stored procedures rather than have embedded SQL. I would like to design the SP in such a way that I can do validation like, if the record already exists, do not INSERT and return an error code to the web page. I would also like to have a main Validation SP that all other SPs will call if a particular error occurs. For example, if a record already exists, it will return an error code of 1. OR ... it will call another SP and send that error code of 1 as a variable which will then display a standard message. Any ideas regarding this and the design of that SP. How would I send the message to the web app Is that a RETURN value Thank You, Marc

Crystal reports query question-   (171 Views)
hi, Im modifying a query for a Crystal Report. The query is for a report. I have 7 fields ,all boolean and the user can pick one or more. It seems that most of the time, only one is selected. I need to add these to the report. Based on the selections they make, I then put the corresponding text value associated with the boolean. I put separate CASE statements in my sql , but Im not going to have room to put those fields in the report. I tried putting them vertically, but the report doesn't look good. Am I on the right track or way off I have the same thing for all 7 fields (below). I managed to squeeze all 7 fields together, making them really small, but when the user has selected something other than the first field displaying on the form, the field appears to the right instead of where it should. How do I do this Not sure about how to do this Another problem I am having is this: I make changes to the report, but when I bring the web page up and select the report, it shows the old report, not the new one. I can't build anything ( I didnt think I had to because the reort is the same ) because I don't have the code-behind - does that matter Can you suggest what I should do
