Hi, we're trying to read from a table and write back to the same table and are having a lot of trouble with blocking. What could we do to prevent our application from hanging due to blocking of this type?
Is there a way to get the last read/write time of a table?
I want to have a few tables, but only allow them to exist if they have been used in the last 30 days. I want to set up a "purge" job to clear out any tables that have not been used in 30 days.
Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew If jdoenew is missing in the 2nd db I will need to write entries like: db1.usr_table.usr_name = jdoenew db1.usr_table.password = tmppassword db1.usr_table.active = 1
INPUT: A table contains 2 columns with data i need. column A=Filename and column B=FileContent
PROCESS: I need to loop through ea record in the table and retrieve columns A and B. Then for ea column i need to write the Content hold in column B into File hold in column A.
I so far found out, that i need a Execute SQL Task in Control Flow querying the table and get columns A and B into 2 variables, plus a 3rd var holding the object. Then the output goes into a Foreach Loop Container. From this point i don't know how to continue. I tried to put a Data Flow Task inside the Foreach Loop, but couldn't find out how i now get the 2 variables to the Data Flow Task and use them to for the file to be written and the content to be placed in the file.
Is there any example similiar to that so i could learn how to start on that?
I have been trying to write a cursor to fetch required data from table but somehow its running forever and inserting duplicate records.
I have a temp table named getInvoice where I have five important columns
1. invoice number 2.group 3.invoice status 4. Invoice Expiration date 5. Creation date time
and some other columns.One invoice number can belong to one or more group and there can be one or more records for a particular invoice number and group.
An example is below :
InvoiceNumber Group InvoiceStatus InvoiceExpirationDate CreationDateTime
My query condition is complex and that is why Im facing problem retrieving the output.I need a cursor for getting distinct invoice number from the table and for each invoice number I need to get the latest record for each invoice number and suffix combination based on creationdateand time column and if that record has invoice status of 2 and also the invoice expiration date can be either null or greater than today's date, then I need to get that record and put it in a temp table.
The query I wrote is below
declare myData cursor for select distinct invoiceNumber from #getInvoice declare @invoiceNumber varchar(30) open myData fetch next from myData into @invoiceNumber while @@FETCH_STATUS = 0
I'm trying to do Sharepoint DR with Log Shipping and every thing configured except one thing which is switch the WSS_Content (Standby /Read-Only) DB to be ready and Write.
I tried from
GUI or ALTER DATABASE [WSS_Content] SET READ_WRITE WITH NO_WAIT
I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1 Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
I have a query that runs for 10 sec on one database( A) and 5 min on another database(B) even though two database have identical scheam, tables, index and statistics..
I ran a profiler and got the below information CPU READ Write Database A: 92051 711956 8774 Database B: 91812 7621589 315822
A query runs on database has a significant larger read and write.. I don;t understand why this is happening? even though these two database have the same structure?? it has the same execution plan as well..
Please help me to get the required result: For each IDS in table1 - change the ids to numbers (eg. for '1,2,3' get the numbers (IntValue) 1, 2 & 3) - in table2, find the maxVal for each number - disply the table1..ids, number, table2..maxVal & table1..idsDesc, order by table1..ids, table2..maxVal & IntValue
I have 2 tables, over milin records each. The Simplified versions of the tables looks like that:
create table table1 (ids varchar(100), idsDesc varchar(100)) go insert table1 select '1,2,3', 'Description 1' union all select '2,3,4', 'Description 2' union all select '1,7', 'Description 3' union all select '16,3,8', 'Description 4' union all select '2,5,6,1', 'Description 5' go
create table table2 (ids int, maxVal int) go insert table2 select 1, 10 union all select 2, 6 union all select 3, 12 union all select 4, 11 union all select 5, 66 union all select 6, 4 union all select 7, 3 -- union all select 8, 5 -- no value for 8 union all select 9, 6 union all select 16, 12 go
I have also function that returns table variable of numbers delivered from given string: create function dbo.fn_StrToIntValues ( @str varchar(1000) ) returns @numsTbl table (IntValue int not null)
The command select * from dbo.fn_StrToIntValues('1,2,33')
Returns --> intValue 1 2 33
Can I use SQL query and not cursor to get the following result ?
I need to update the Tn column from the default 9999 for the 3 rows in this table where the dealid is 12345 based on the value in the datex column so the row with the 'highest ie most recent date' gets a 0. I then need to assign the value 1 to the next highest and so on until all rows (in this case 3) get incrementing integer values. It's easy with a cursor but can't get my head round doing it in a set-based way Any ideas
FETCH NEXT FROM new_cur2 INTO @new_rec_ibaid,@new_rec_rid,@new_rec_attr,@new_rec_val,@new_rec_orig_rid delete from new_iba_3 where current of new_cur2; --HERE
close new_cur2; deallocate new_cur2;
select * from new_iba_3
WHEN I TRY TO DELETE FROM new_iba_3 IT GIVES CURSOR IS READ ONLY BUT UPDATE WORKS ON THIS TABLE I HAVE NOT DECLARED THIS CURSOUR AS READ ONLY THEN WHY IT IS GIVING THIS ERROR

We currently run sql 2005 server and also sql express in our dev environments. We use sql express as an offline store (smart client). We have a similar/exact schema on the sql 2005 server and also the express.
We use the auto attach feature to connect to the express version of the database. Both the developer machines and the one that is running the sql 2005 server have exactly the same hardware configuration. The only difference may be that the server box is not running the VS.Net environment. The disk space etc is pretty much the same. Actually we run another database server(DB2) on the 2005 server machine.
We have observed that sql express is much slower and queries execute much slower aswell. For example, this may not be a totally scientific way of checking but a long running query on the server took only 2 minutes while on express it took longer than 9 minutes. The schema and data etc are the same.
Is there something we need to look into as far as read write speed/performance goes ?
I am using a Script Component and I have a Read/Write Variable varStatusCase (as assigned in the Custom Properties of my Script Component). I used this inside my script to get a specific value. However, when I ran it I get this error:
The collection of variables locked for read and write access is not available outside of PostExecute.
I have a table which table has :Identity Column (Identity), Schema name and Table_Name.
So I would like to write a cursor For each Table Count(*) from Table--@Cnt Int , Schemaname and Tablename need to store another table.
Implement a USP, using a cursor that scan the table, generate select count statement from configuration table and fire the select count statement and record the result of the query in the log table :
how can I write a cursor and Import Those results into to Another table.
I am trying to write a cursor to update certain rows in a particularorder as follows: (I need the cursor version, not SQL, as the updatelogic depends on the order of rows and some other conditions. Iremoved the Order-By clause from the statement to simplify it; itgives the same error message with or without it.)DECLARE prod_cursor CURSORFORWARD_ONLYKEYSETFOR SELECT 1 FROM all_products WHERE p_qty = 0 FOR UPDATEThis gives the following error message: "FOR UPDATE cannot bespecified on a READ ONLY cursor."I have tried a few different combinations of cursor types (like SCROLLinstead of FORWARD_ONLY) but they all give this error, although thestatement seems identical to what I have seen in the books and inbooks online.Any ideas on how to convert this into an updating cursor?
Okay, maybe I'm getting ahead of myself. Using SQL Server Express, VWD and .net 2.0 I've figured out how to drop a Table Column Constraint or Default Value/Binding and then Create it again using a stored procedure. What I can't figure out is how to retrieve that column's constraint value and write it to, say a label, in an aspx page, simply for reference. Is it possible? In this case the Data Type of the column is money. I'm using it to perform a calculation to a column with a value that the user inserts into another column. (Column1(user input) minus Column2(with Default Value) = Column3(Difference). I just want to read Column2's Default Value for reference so I know whether to change it or not.
Hi, I was reading that many of these high traffic websites actually have 2 databases, 1 database is used ONLY for reads, while the other is for writes.
How does one go about creating such a setup? How does the database where writes are allowed replicated the data to the read only database server?
Hi,I would like to use database locking mechanism to control access to anexternal resource (like file system).What I need is1. an exclusive (write) lock conflicting with any access to theresource (both for read and write)2. non-exlusive (read) lock conflicting with writes onlyHow this could be done?I'd appreciate any reply.Vadim
Hello Guys, in SSIS I want to get a set of data and do some modifications on it before I insert it into the destinatipn. So far so good. Some of the modifications will include comparisions between two columns and if certain field is NULL then I want to get the value from the other one I was comparing to. When using conditional splits, I only get the rows to be redirected so that I can do whatever next. However, I want like use the variables as a storage so that I can put the value of one of the two columns in this variable which will be actually loaded into the destination finally. Any help? Thanks

I use excel as an interface to write query to retrieve data from a database in network drive. My problem is everyone can open and edit my query. Of course, the univeral database access user name and password will ask but everyone know this. How can I put password to prevent any query modification?
