I'm newer to MS SQL, but have a programming background, so I'm going to try to describe what I'm doing in that sense.
What I want to do is pull an entire column of data from one table, and insert it into a column in another table. Typically, I would do this with an array and while loop or something similar. I've figured out how to do a while loop in SQL, but the array situation has me stumped. I tried reading http://weblogs.sqlteam.com/jeffs/archive/2007/06/26/60240.aspx that article, however it referred to a procedure, and I have no background or experience with procedures.
Any sort of idea or document on a technique to do this would be most appreciated, thank you!
Books online mention the existence of sample code for several custom tasks, including the one mentioned in the title. But, when I try to find this code in the location mentioned it is nowhere to be found.
I have run a search on the rest of my drive and come up empty.
Im trying to use VB.net 2005 to write a sample app to access a DB. Are there any samples for this and any samples of how I go about making the DB in the first place?
hi, i'm passing a string to a Stored procedure(sp).this is string is delimited, say, mon:tue:wed..is there a way in a sp to parse this string out an store it in an array and then use a for i=i to..whatever.. loop to access each element?
I have data I am retrieving using a datareader...and SQLSERVER It could return 1 row of information or perhaps 3 rows of information I need to know how to use an array here I would guess so I can access each element in this row or rows.
HOw might I use reader.read and get it into the array
I am creating an application for booking events. Each event has several dates and each date has a fixed amount of available seats.
Currently in the events table I have a field for the number of available seats and a field for the string of dates that are later parsed into a listbox control.
The problem with my current setup is each date is sharing the same number of available seats so if date Event A is decemented 10 so will Event B.
I need some way to associate each date with it's own number of available seats. What is the best way to do this? An array? If so how do I store an array in the DB?
Hi;I have been writing a lot of short tsql scripts to fix a lot of tinydatabase issues.I was wondering if a could make an array of strings in tsql that Icould process in a loop, something likearray arrayListOfTablesToProcess = { "orders", "phone","complaints"}for( int i = 0; i < arrayListOfTablesToProcess.length; i++ )delete from arrayListOfTablesToProcess[i]Can you do something like this in tsql?I should probably stop asking all of these questions.Is there a good book on TSQL alone ( I'm not interested in wizards,just scripting )...that is short?Steve
Hi everyone My stored procedure accepts 2 parameters: names, number of names like this: (name1, name2, name3,3) Problem is: the number of names changes each time i want to run it. Some time it is: Name1,1 and other time it is: name1, name2,2. So every time i run it i need to change code. I thought "arrays" might solve that problem but i never met arrays in sql2005. Does it exist ? Case answer is "no": What is it to replace arrays and solve the above problem? Thanks
I'm have a stored procedure that iterates through a list of numbers and adds an item for each number (user id) some of these ids are duplicates which is fine even necessary for the first part of my query but for the last I need to ensure that no duplicates id's are passed to the stored procedure, in this case called 'spInsertForBackupNote'. My thoughts here was to do something like this:
SET @Note_Buffer = @UserID -- @Note_Buffer being some kind of array?
IF @Note_Buffer = @UserID -- If its been added to the buffer we dont execute sp BEGIN Do Nothing here END
ELSE
BEGIN EXECUTE spInsertForBackupNote @FK_UserID, @FK_NoteID END
I know this would never work because it would always be false since I just added the same userid to the buffer that I want to add. But I think you see my problem. I know it should be an easy one but my TSQL is limited. I've posted the whole sp. Hope someone can help.
Can any one help me with a sample code, which can take an array of elements as one of it's parameters and get the value inserted into a table in a stored procedure.
I want to pass my stored proc a list, and either loop through it as a list or (better) turn it into an array and loop through it that way to insert it. Psuedocode would be...
Loop from 0 to ListLength begin INSERT Transaction_Data end
I am glad to announce that there is now a version of my article "Arrays andLists in SQL Server" for SQL 2005 available on my web site.THe URL for the article ishttp://www.sommarskog.se/arrays-in-sql-2005.html. If you are curious aboutthe performance numbers they are in an appendix athttp://www.sommarskog.se/arrays-in-sql-perftest.html.The old version of the aritlce remains, as the new article covers SQL 2005only. The old version is now athttp://www.sommarskog.se/arrays-in-sql-2000.html.The old URL, http://www.sommarskog.se/arrays-in-sql.html leads to a pagethat links to both articles.And the reason that there are two articles is simply that SQL 2005 addsso many new features: nvarchar(MAX), the CLR, the xml data type, CTE thatall can be used in the realm of arrays and lists.--Erland Sommarskog, SQL Server MVP, Join Bytes!Books Online for SQL Server 2005 athttp://www.microsoft.com/technet/pr...oads/books.mspxBooks Online for SQL Server 2000 athttp://www.microsoft.com/sql/prodin...ions/books.mspx
Hi, I'm using Visual Studio and Visual Basic to save data about members in a database. I use SQL-database as it's included. However, I'm new to this saving in the datbase and wonder how I can at the best save data about a member without having to index each value in the arrays: The array has 2 index and is declared dim Results(6, 50) as string Of course, I can do results11, results12,... results150, results21, ...results250.... But it seems rather awkward to do it this way. I'm sure that there is a better way. Thanks, any assistance is appriciated! Best wishes, Per
SelectCommand="SELECT * FROM Table1 WHERE Field1 IN @target"
And my parameter looks like this:
<asp:ControlParameter Name="target" ControlID="CheckBoxList1" PropertyName="SelectedValue" /> This code gives me a syntax error near @target. Someone got a solution?
i want to know how i can pass multiple values in the form of arrays to a stored procedures.
the technique by which i pass multiple values to a stored procedure beginning along with declarations are as follows:

to the insert procedure i am passing multiple values with the help of ~ sign and in the procedure the individual values are separated by identifying the position of ~ sign and the no. of records which have been passed. For which a complicated stored procedure has been written.
i want to pass multiple values in an array, so that my stored procedure becomes simple and runs faster. So, if someone tells me how to pass arrays to a stored procedure (with code example), it will be of real help.
Someone recently tried to tell me that it is possible to pass an array to a stored procedure.
I have tried creating procedures with the 'table' datatype for the parameters but the attempts fail with a syntax error.
We currently workaround this limitation by passing the equivalent of an array to temporary tables and selecting from those tables as needed within our stored procedure but if we can circumvent this by passing an array, we'd definetly like to try that instead.
My SQL knowledge is limited so if I get stuff wrong then correct me... but I can imagine this task will be quite testing...
I am working on a system that logs ([Audit] table) the changes to fields on some tables using a Trigger on UPDATE. I need to produce a 'quick' report that returns the date when the tables overallStatus field was set to 1.
In the [Audit] table I can find all the field changes for the record in question using this SQL...
select * from audit where rowid = 1309606 order by auditID asc
My problem is filtering this data. The fields I need are formatted as below, see records returned, in ASC order...
So need to find when 1309606's overallStatus was changed to 1. Manually looking at the data, I can see overallStatus was modified in 3 of the above 5 [Audit] records. It started life as 0, then went to 1 and then to 3. I'm aware that I need to look at the previous Audits date for when it was changed to the value I'm looking for... So it was changed to 1 on 2008-04-25 10:51:47.930.
What is the best way to approach this problem? I'm hoping to use T-SQL only and not have to use an external scripting language, unless I can embed vbscript or jscript inside a T-SQL function and then use arrays, etc?
Somehow I need to convert the ASCII(127) seperated list of fieldname into an array or list, find the index of the fieldname 'overallStatus' and then lookup that value in the datafield.
Hope that makes sense and any help would be great!
How do you all recommend storing ordered pairs in SQL Server 2005? I plan to add one record for every data point but this will generate many records and requires an extra field to relate the points together. Are there any better ways to do this? Can the data still be searchable or does it have to be unpacked first?
I'm getting ready to install SQL Server 2005 Enterprise for the first time and I have a question about the directory location of the log files and the data files. I have 3 RAID arrays on my server, 1 for the OS, 1 for SQL Logs, and 1 for SQL Data.
Here's my issue. I want to install the logs on the Log array and the SQL data on the SQL data array, however, during the installation I can't find anything that allows me to select certain directories!
I have a bunch of SPs that all rely on a UDF that parses a commadelimitted list of numbers into a table. Everything was working fine,but now my application is growing and I'm starting to approach the 8000character limit of the varChar variable used to store the list.I would like to change the UDF only and avoid having to dig through allof my stored procedures. I was hoping to use the text datatype toallow for much larger lists, but I am unable to perform anymanipulations necessary to parse the list into a table. I have triedPATINDEX, but it alone is not enough without the text maniuplations andI don't think the sp_xml_preparedocument can be used in a UDF.Anyone with any thoughts on managing large arrays in t-sql?thanks,Matt Weiner
I know that SQL Server itself does not support passing arrays to its procedures. But I need an alternative that will allow me to "duplicate" the same functionality.
I have the following information stored in a Class:
UserInfo: Where I keep the variables 1-12 PageInfo: Where I keep variable 13 (the list of pages)
I need to store this information in my SQL Server Database. So far I found three possible methods but I'm not sure which one has the better performance:
First Method: the easy one 1. Call the SaveUserInfo stored procedure 2. Loop through the pages array and call the SavePageInfo stored procedure for each page item in the array
Second Method: Passing a delimited string to the stored procedure 1. Call the SaveUserInfo stored procedure 2. Pass a delimeted string to the SavePageInfo stored procedure. The stored procedure will split the string and save the pages into the database. The string would look like this:
Third Method: Passing and XML File to the stored procedure The stored procedure will read the XML file and store the information into the database.
What method is the best for performance?? As you may see this is for tracking the user navigation through the website. For the first method I worry about the number of call to the database; for the Second and Third method I worry about the lenght of the string or XML file to pass to the stored procedure.
I have a 2-node cluster environment & I am planning to replace it with new hardware. Currently I am using MSA1000 Disk arrays. Now I would like to move my storage to SAN.
What are the necessary pre-requisite and actions to do this. Any particular thing, I must take care in planning.
I have a matrix table which has two groups in the columns
I am trying to create a multileveled document map which i have succeed by
1. Edit Group 1 properties and setting the document map properties to the name of the field 2. Edit Group 2 properties and setting the document map properties to the name of this field and making the parent group the name of Group 1
The document map appears with the correct groups and name , however when I click on the values it doesnt take me to any where !!! It refreshes the screen but it doesnt go anywhere !
Can someone please help me troubleshoot this or know what i may be missing
When i publish a report to our reporting services site, it comes with a document map that I cannot seem to get rid of and is really annoyong to users. How do I stop this from happening and appearing?
Hello Everyone and thanks for your help in advance. I am developing a document storage application for an intranet that will store various Word, Excel, and PDF documents. Most of the examples I see utilize SQL Server and an image field rather than the FileSystem Object to store documents. My concern with this method is that some of the documents may be several hundred pages (not exactly sure of the actual file size yet, but they must be fairly large). My question is, where does the use of SQL Server become impractical for this type of application? Any insight would be greatly appreciated. Thanks.

I have a database which stores documents (e.g. policies and guidelines)in our content management system. The follow relationships exist:Documents (1-to-Many) LinkTableKeywordLink (Many-to-1) KeywordsDocuments (1-to-Many) LinkTableAttachments (Many-to-1) AttachmentsDocuments (1-to-Many) LookUpSubjectsDocuments (1-to-Many) LookUpDocTypeWhen the user conducts a search I want the SQL to check if the stringthey enter is present in:* the Title, Author, Summary fields of Documents OR* the Title or Path of the Attachments* the Keywords that are links OR* the Subject that is linked OR* the DocType that is linked.Is this possible in one SQL query. I have tried the following:SELECT DISTINCT Documents.Document, Documents.Title,PriorityFROM Documents,Attachments,Keywords,LinkTableAttachments,LinkTabl eKeywordLinkWHERE((Documents.Document=LinkTableAttachments.Document ID andLinkTableAttachments.AttachmentID=Attachments.Id) OR(Documents.Document=LinkTableKeywordLink.DocumentI D andLinkTableKeywordLink.KeywordID=Keywords.Id))AND (Documents.Title Like '%SEARCHSTRING%' OR Documents.Author Like'%SEARCHSTRING%' OR Documents.Summary Like '%SEARCHSTRING%' ORKeywords.Keyword Like '%SEARCHSTRING%' OR DocType.DocType Like'%SEARCHSTRING%' OR Attachments.AttachmentTitle Like '%SEARCHSTRING%'OR Attachments.Path like '%SEARCHSTRING%' or Subjects.Subject Like'%SEARCHSTRING%')AND StartDate<=getDate() and ReviewDate>getDate() order by Titlebut this causes, perhaps understandably, a timeout error.Any thoughts?Thanks!Steve
