I have created a small (5 fields) Access table which I will be
converting to MS-SQL Server format when the ASP code has been
completed. It is basically a collection of links to news releases from
mining companies. The group of people who will be browsing this
database want to know if the news release pertains to their area.
Sometimes the news release pertains to multiple areas if the mining
properties are scattered. Given the possibility of a one-to-many
relationship, ie one news release, many areas, I created an additional
table for the areas. I created the ASP code to pull down the news
release information, then loop through the area records such as:
set RSNewsRelease = Server.CreateObject("ADODB.Recordset")
NewsRelSQL = "Select date, company, title, newsreleaseID from
newsreleases;"
do while not RSNewsRelease.EOF
'display news release date, company and title
response.write RSNewsRelease(0).Value & RSNewsRelease(1).Value &
RSNewsRelease(2).Value
'loop through areas
set RSAreas = Server.CreateObject("ADODB.Recordset")
'run query
do while not RSAreas.EOF
'display areas
Loop
set RSAreas = nothing
Loop
In other words, the only way I could get the results I wanted was to
set the Recordset to nothing, then reset it with each iteration of the
outer loop.
I know this question has been asked. And the usual answer is don't usecursors or any other looping method. Instead, try to find a solutionthat uses set-based queries.But this brings up several questions / senarios:* I created several stored procedures that take parameters and insertsthe data into the appropriate tables. This was done for easy access/usefrom client side apps (i.e. web-based).Proper development tactics says to try and do "code reuse". So, if Ialready have stored procs that do my logic, should I be writing asecond way of handling the data? If I ever need to change the way thedata is handled, I now have to make the same change in two (or more)places.* Different data from the same row needs to be inserted into multipletables. "Common sense" (maybe "gut instinct" is better) says to handleeach row as a "unit". Seems weird to process the entire set for onetable, then to process the entire set AGAIN for another table, and thenYET AGAIN for a third table, and so on.* Exception handling. Set based processing means that if one row failsthe entire set fails. Looping through allows you to fail a row butallow everything else to be processed properly. It also allows you togather statistics. (How many failed, how many worked, how many wereskipped, etc.)?? Good idea ?? The alternative is to create a temporary table (sandboxor workspace type thing), copy the data to there along with "status" or"valdation" columns, run through the set many times over looking forany rows that may fail, marking them as such, and then at the end onlydealing with those rows which "passed" the testing. Of course, in orderfor this to work you must know (and duplicate) all constraints so youknow what to look for in your testing.
Im having a issue. Im not sure how I am going to carry out but I have two tables in SQL server 2005 TABLES Category SubCategory (PK)CategoryName (PK) SubCategoryNameCategoryID SubCategoryIDDate Date (Just shows the date inserted) (FK)CategoryID On the front page, I need to have it querys out the CategoryName from Categorys but also querys out all....Well not all but atleast 5 subcategorys that relate to that categoryName. Once its down it moves to the next category and does the same and so on. Does anyone know the trick ?
How due I set up a database in SQL 7 to be accessed via the web and to have queries performed on it. What else do I need besides NT 4.0 SRV Pack 6. I need detailed instructions, really appreciate your help. Thank You!
i know that db.owner.tablename works in the query analyzer, but what i really appreciate from anyone is how to apply this in vb6 code since the recordset is opened only from one db using the following syntax:
Dear friends, ours is a product company,we are delivering our product presently in sql server.in future we r planning to deliver the product in all the big databases.
now the problem is conversion of the module to other back end.there are so many functions and procedures as well.some will execute only at runtime.through some where string.
is there any tools those can automatically convert queries, functions and procedures to the other back ends?
or is there any open source code to convert automatically?
I'm working on an electronic register which people use to sign in and out of a building. It uses 3 tables, one to store personal information (Name & Visitor Number), one to store what time they come in, and one to store what time they leave. Visitor Number is the primary key in the Visitor_Info table, and is used as a foreign key in the other 2 tables.
I've been asked to put in an 'emergency print' function where, when you click the print button, it compares the data in the time in database and the time out database and prints a list of people still in the building.
So, what I'm trying to do is create a SQL query that will give me this information. Having never used SQL before, it's a little tricky. I've spent the last few days looking at tutorials on the net and learning about queries and this is what I've come up with:
Select Time_In_Table.Visitor_Number Not Union Select Time_Out_Table.Visitor_Number
If I'm right (and I'm probably not), this will give me the people who are in the time in table, but not in the time out table.
Can someone please help me by letting me know what I'm doing wrong in the statement above, and also, advise me as to where it goes since none of the tutorials I've found cover where to put the statement in my programming? At a guess, I'd say it goes in the print button click function.

Say for example DatabaseA has failed over to the mirror. Then you call a stored procedure in that database that queries a table on DatabaseB that is on the principle (has not failed). What happens? Is mirroring smart enough to know that? If not, are there workarounds? Perphaps manually failing over the other databases?
I am using SQL 2008 r2. I have two SQL Queries from 2 different database but they share one server. I need to linked these two SQL Queries as they share the same Primary key which CustomerID see example below
Query 1
Database::Student Select StudentID , FName, LName From Student
Query 2
Database ::Finance Select StudentID,Tution FROM Payment
I need to be able combine two query which come from two database but they share one server.I would like to use two temp tables so that I can perform a left / right join to retrieve the data by linking two queries using primary id which they both share ( StudentID)
Summary : I have two DB's on the same server. I have two simple select queries for each DB which work correctly.
As a part of DBA, I used to execute various SQL files. Most of the time, it is like a manual effort to execute the files individually.
I am looking to automate the process, like a single click to execute all the .SQL files.
The main hurdle I have is, some files needs to be executed in A1 database, some in B1 database and some other SQL files need to be executed in C1 database. In this scenario, I need to pass the DBName information to the powershell query dynamically.
My design for this requirement is, say each .SQL file need to contain a template like
@DBName = 'your Database name' @Executeon = 'When to execute'
In this case, the powershell first need to read the SQL file and finds the value for @DBName and replace it in the powershell query and execute the SQL files automatically.
Is it feasible ? Or any other alternate easier way to proceed.
I'm using connection strings to SQL Server Express that have the form
"DataSource= .SQLEXPRESS;AttachDbFilename="(path to my development directory)CurrentDevelopmentDB.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
I'm assuming this works because the DB is already there, created "manually".
How might I build a connection string for a SQLCommand for a "Create DataBase" query?
I'm confused about what the AttachDbFileName would be, or if there would be another variable in its place, since there's no file yet.
Hi! we have no Business Intelligence solution in my job and the general manager asked for a query and reports system where he (and other section managers and non IT staff) could query the corporative database (we work in healthcare, so it's mostly about patients, clinic histories, treatments) so I will propose them SQL SERVER 2005. I'll tell you my general idea and maybe you could tell me if I'm right: Through Integration Services we will load our data from the corporative database (it's Borland's InterBase) and generate a datawarehouse (now we don't have a datawarehouse) then through Reporting Services we can query this datawarehouse to generate different reports (this reports can be generated for non-technical staff, but staff who knows quite a lot about for example the different treatments that different groups of patients follow, so this staff may want to query about which patients followed which treatment in a period of time and generate by himself a report about that). And through Analysis Services we could (in a future) generate some OLAP solutions, Data Mining etc
But for the query and report system it could be enough to start with Integration Services and Reporting Services? it's very important for this system to work efficiently in terms of time: the non-technical staff generates the query and in seconds receives the report result... some of this non IT staff who will use the system knows exactly which information we house in each InterBase table, so through this system they would like to generate their own queries and reports (this is a different level of non-IT staff who is in between a Medical doctor and a Software engineer, this staff does have some technical background specially in SQL.
So my idea is to have an SQL SERVER 2005 to which this staff gets connected via LAN (all this system runs locally in one corporative place, will not run through Internet) feeded by the InterBase corporative database and delivering efficiently queries and reports... is this possible? could I test this using the trial free 6 months version? and after that if everything's working fine how much will I have to pay for 15 persons to access the SQL SERVER 2005 for keeping using the system?
We have a client who runs SQL Server 2000 queries on one database server and performance is approx. 4 seconds. If the database is backed up, no tables in the query or indexes on these tables are modified (we may run a small script that affects stored procedures, views, etc.) the query can run virtually forever.
The customer is runing a cluster and we are running a stand-alone. Although, the two environments that they run in and have these wildly different results in are the same.
The queries are not worth listing (join a couple of tables and views, select a few columns, put on a few conditions--nothing crazy).
Is this normal behavior for MS SQL Server?
I've personally seen where a database is backed up and query plans and performance are different from one server to another, but we are looking at extreme cases here. In fact, on the second server, the majority of the queries are faster and only a couple run very slowly.
Also, the query optimizer seems to be making poor decisions at this custoemer. For example, two tables will be cross joined (forming over 200 million records) and then table scans ensue. The process in some cases will take a 4 second query to 45 minutes.
To me none of this makes any sense. I've been working with SQL Server since 1997 and have not experienced any type of performance problems or variances of this magnitude. Although this is a 6GB database, SQL Server 7 ran on a terabyte without even blinking, so I wouldn't understand why this would have anything to do with it.
Also hampering our efforts is that we do not have easy access to this SQL Server database to get our hands on it and debug these issues.
Does anyone know of a way to examine these issues in a "system wide" manner to determine what the problems could be since the problems are not specific to the database (i.e. .bak file) but seem to be specific to the server?
They have also had database corruption (an index that wouldn't update) and had to roll back the database. Would that indicate that the MDF/LDF's are unstable? Is there a way to figure out if there is some type of MDF/LDF file structure corruption?
I am running MS SQL 2000 server. The table involved is only about10,000 records. But this is the behavior I am seeing.The local machine is querying the table looking for a particularrecord. Everything works fine.The remote amchine goes to clear the table and then insert all 10,000records, into the table the following happens.1) the local machines queries do not compilete until the remotemachine is done.2) the remote machine can take up to 6 minutes to do these 10,000insert operations. So nothing on the local machine works right forthese 6 minutes.I do not have access to the remote machines source to see what isrunning but I am told it is simply a for loop with a insert query init. Nothing of a locking natture.Any idea the types of things I should look for to track this down? Ifound this by doing SQL profiler profiling and finding the remoteoperations. Turn these operatiiosn off and the local machine worksfine again, with no other action.Thanks,David
I had my database in 6.5 which i upgraded to 7.0 using SQL Server upgrade wizard.Then I created full text catalog. When I say incremental population It gives me warning that You can create full text indexes but can not execute queries against it as the database is still in SQL server 6.5 mode.What is the reason behind this?
I have been trying to export an sql2000 database to sql2005 with no luck. I continuosly get the error
Msg 0, Level 11, State 0, Line 0
A severe error occurred on the current command. The results, if any, should be discarded.
I have looked upon all support material and have installed the latest sql2005 service pack, but this has not fixed the problem. a simple query as:
select * from [transaction] ta,transactionentry tr
where tr.transactionnumber=ta.transactionnumber and
glacctid=6 and ta.[time]> '3/01/2006'
would produce this fatal error.

This problem is happening on some of the most important tables in the database.
I want to loop through a recordset and do inserts into another table based on each record.
The way I have been doing it is copy my key data into a temp table, Loop through temp finding the max ID Doing what I need to do, deleting the max, then finding the new max and looping until no records exist.
I know there has to be a better way. The table I am working with is millions of records. Thanks in advance, Chris Reeder
I need to loop through a set of tables and move the data through a data pump from one server to another. This set of tables is dynamic so I have greated a global recordset and the looping is working fine.
During the looping process I need to change the transformations for each table so the source, destination, and transformation of the datapump are correct for the next table in the loop. I am using a VBS to handle this right now but cannot get the transformation to change. I essentially want to auto-remap using a vbs script. Is this possible?
Hello clever people I have a table that holds duplicates that I want to change into a table that has no duplicates. The current table is this name compound_id integer name varchar(150) name_type integer
This table stores chemical names. There is no primary key in the table so there are multiple compound_id's. I think the original idea was to have four name-types 1 = chemical name 2 = a description of the chemical 3 = a synonym of the chemical 4 = a formula of the chemical
I have created a new table called compound_name with this structure
id int primary key (auto identity) compound_id int used as a foreign key compound_name varchar(150) compound_desc varchar(250) compound_synonym varchar(150) compound_formula varchar(50) compound_trade_nme varchar(50)
I have also started to populate the new table by running this code insert into compound_name(compound_id,compound_name) SELECT DISTINCT compound_id, name FROM dbo.name WHERE (name_type = 1)
Now I need to somehow loop through the name table getting distinct compound_id's, and perform a case when name_type = 2 (which is synonym name_type) Then inside the loop update compound_name.compound_synonym for each compound_id which matches name_type 2 Then case 3 do the same for name_type 3 which is the name_type for descripton Then case 4 do the same for name_type 4 which is the formula
Hi there, I am new to SQL and am having trouble looping a script. I have the following script that needs to be refreshed a large number of times, or needs to be looped indefinitely until stopped:
select df.tablespace_name "Tablespace", block_size "Block Size", (df.totalspace - fs.freespace) "Used MB", fs.freespace "Free MB", df.totalspace "Total MB", round(100 * (fs.freespace / df.totalspace)) "Pct. Free" from dba_tablespaces ts, (select tablespace_name, round(sum(bytes) / 1048576) TotalSpace from dba_data_files group by tablespace_name) df, (select tablespace_name, round(sum(bytes) / 1048576) FreeSpace from dba_free_space group by tablespace_name) fs where ts.tablespace_name = fs.tablespace_name and df.tablespace_name = fs.tablespace_name(+) ;
I know this question may have a very easy solution, but I have no idea how to solve it.

Hi All, I would like to know the best way to approach the following requirement: I have an ASP.net 2 web site which gets its data from SQL 2005. I am trying to run a series of 'rules' which are SQL where statements stored in a table, against rows stored in another table. I open the 'Rules' table looping through all records. I copy each rule to a string and put it on the end of the SQL statement so that the rule will only be appended if it passes the rule... this may be a little confusing. The rules process will fire when the details have been submitted to the database. Table containg rules would contain something like: ID, RuleSQL 1, (ClientAge >18) 2, (ClientIncome>10000) 3 Etc... This a very simplified version of the table but gives the general idea. I currently use ASP.NET 2 and sqlconnections/datareaders to do this. I would like to know if there is a way of doing the same thing server side using Transact SQL because that would (I believe) speed up the time taken to perform all the tests as i wouldn't need to rely on ASP to open all recordsets and append the data. If the ASP route would be the standard way of doing it and is not likely to have a detremental effect on performance then i am fine to stick with it because i know it works. any comments or suggestions would be welcomed. Thanks, Ian
I have an array (12,2) of values plus a profile variable that I want to pass as parameters while writing to a database. I've been told that I've set up the parameters wrong, and they cannot be changed every time I loop using the method I'm using. But I have no idea how to use any other method. Please... I'm down to the wire in terms of deadline here. I have until midnight to get it uploaded and running online. [CODE]Sub WriteClasses(ByVal CreditsArray) Dim i As Integer Dim EnrollDb As SqlConnection Dim cmdEnroll As SqlCommand EnrollDb = New SqlConnection("Server=LONNASQLEXPRESS;Integrated Security=True;database=LGordonTouroReg") cmdEnroll = New SqlCommand("INSERT INTO Enrollment (SectionID, Semester, Year, ClassID, StudentID) VALUES (@SectionID, 'Fall', '2007', @ClassID, @StudentID)", EnrollDb) EnrollDb.Open() For i = 0 To 12 cmdEnroll.Parameters.AddWithValue("@SectionID", CreditsArray(i, 2)) cmdEnroll.Parameters.AddWithValue("@ClassID", CreditsArray(i, 0)) cmdEnroll.Parameters.AddWithValue("@studentID", Profile.StudentID) If Not CreditsArray(i, 0) = "" Then cmdEnroll.ExecuteNonQuery() Response.Write(CreditsArray(i, 0) & " has been added to your schedule.<br/>") End If Next i EnrollDb.Close() End Sub[/CODE]
lets say i have a stored procedure (for insert command) which i am calling in my code to execute. The user provided data is being stored in a array. My class takes the stored procedure name and also takes parameters name and types. Is there any way to loop through the parameters, (various columns in the table which is of diffrent data type ie varchar, int, etc). How to implement it?
