Multiple SET/WHERE Within Single UPDATE?

Mar 21, 2008

Can an Update statement support multiple SET/WHERE clauses? The following example won't work, but this is what I'd like to be able to do:

Code Snippet
UPDATE [CPSAgacar].tmp_CTA2

SET [Admit Date] = NULL
WHERE [CPSAgacar].tmp_CTA2.CalcAdmitDate IS NOT NULL

SET CalcDischDate = Discharge
WHERE [CPSAgacar].tmp_CTA2.CalcAdmitDate IS NOT NULL AND CPSAgacar].tmp_CTA2.CalcDischDate IS NULL

Thanks.

Update Multiple Records From A Single ASP.NET Webpage

Mar 3, 2004

Got a beginner question here...
Let's say I have a database table that houses server information with four columns: make, model, serial #, ip address. And assume there are ten rows with that information filled out. How could I display all the rows of information on a single webpage (ASP.NET), with all the fields being editable; and a single save button that would send any changes to the database (in reality I guess it would be sending all rows and fields to the database, and just overwrite the previous data).

Could a page such as that be created using FrontPage 2003 or Dreamweaver MX 2004?

This would be strictly for updating information. I would have a separate form for adding a new entry.

Thanks for your help.

Update Multiple Rows In A Single Query?

Jul 30, 2007

I know this isn't right but I'm trying to build a single query in PHP to re write the sortorder column starting at 0 and writing every row in order.

Code:

update categories set (sortorder=0 where catid=32), (sortorder=1 where catid=33),(sortorder=2 where catid=36) where userid=111

PHP Code:

$qt="update categories set ";
for($i=0;$i<$num;$i++){
    $a=$i+1;
    $qt.="sortorder=$i";
    if($a<$num){
        $qt.=", ";
    }
}
$qt.=" where userid=111";

Using PHP I can amend the loop above to slot in a row I want so I can change the sort order.

unfortunately I'm not sure how to build such a query in mssql, can anyone help?

Update Multiple Varbinary Records With Single Sql Statement

Jan 16, 2007

I am renovating an existing application and am converting the existing passwords into hashed values using SHA1. I know how to compute the hashed values as a byte array for each record. What I don't know how to do easily is update all of the records i a single call to the database. Normally, I would just do the following:UPDATE HashedPassword = someValue WHERE UserID = 101;
UPDATE HashedPassword = someOtherValue WHERE UserID = 102;
...

What I don't know is what someValue and someOtherValue should be. How do I convert my byte array into string representation that SQL will accept? I usually execute multiple statements using Dim oCmd as New SqlCommand(sSQL, MyConn) and then call oCmd.ExecuteNonQuery().
Alternatively, I found the following code that uses the byte array directly but only shows a single statement. How could I use it to execute multiple statements as shown above?'FROM http://aspnet.4guysfromrolla.com/articles/103002-1.2.aspx

'2. Create a command object for the query
Dim strSQL as String = _
"INSERT INTO UserAccount(Username,Password) " & _
"VALUES(@Username, @Password)"
Dim objCmd as New SqlCommand(strSQL, objConn)

'3. Create parameters
Dim paramUsername as SqlParameter
paramUsername = New SqlParameter("@Username", SqlDbType.VarChar, 25)
paramUsername.Value = txtUsername.Text
objCmd.Parameters.Add(paramUsername)

Dim paramPwd as SqlParameter
paramPwd = New SqlParameter("@Password", SqlDbType.Binary, 16)
paramPwd.Value = hashedBytes
objCmd.Parameters.Add(paramPwd)

'Insert the records into the database
objConn.Open()
objCmd.ExecuteNonQuery()
objConn.Close()

Transact SQL :: How To Update Multiple Rows In Different Transactions In A Single Table

Jul 16, 2015

We have control table which will be useful whether we need to start the job or not. If we are starting the Job we will make it to 1.

Below is the Table Structure.

Table Name IN_USE_FG
CUST_D 0
PROD_D 0
GEO_D 0
DATE_D 0

Now we have different packages for 4 tables data loading. These 4 packages will start at a time. Before going to load the data we have to make the Flag to 1 and after that we have to load it. Because of this we have written Update statement to update the Value to 1 in respective Package.

Now we are getting dead lock because we are using same table at a same time. Because we are updating different records.

Integration Services :: How To Update Multiple Single Excel Cells Using SSIS

Sep 3, 2015

I have created an SSIS package which processes daily financial information to a sql server database. These processes are to be outputted to excel spreadsheets to a readable report format for management to review. Some of these reports are laid out in a way that is not just tabular output but requires customized placement of data on an excel spreadsheet to specific cells.

I am able to place an initial resultset of a query output from the database in a tabular excel template through SSIS but the issue is at the end of that placement in the spreadsheet I am required to place another output below that tabular output in a different format from the initial output which I have shown below.

Multiple Columns With Different Values OR Single Column With Multiple Criteria?

Aug 22, 2007

Hi,

I have multiple columns in a Single Table and i want to search values in different columns. My table structure is

col1 (identity PK)
col2 (varchar(max))
col3 (varchar(max))

I have created a single FULLTEXT on col2 & col3.
suppose i want to search col2='engine' and col3='toyota' i write query as

SELECT

TBL.col2,TBL.col3
FROM

TBL
INNER JOIN

CONTAINSTABLE(TBL,col2,'engine') TBL1
ON

TBL.col1=TBL1.[key]
INNER JOIN

CONTAINSTABLE(TBL,col3,'toyota') TBL2
ON

TBL.col1=TBL2.[key]

Every thing works well if database is small. But now i have 20 million records in my database. Taking an exmaple there are 5million record with col2='engine' and only 1 record with col3='toyota', it take substantial time to find 1 record.

I was thinking this i can address this issue if i merge both columns in a Single column, but i cannot figure out what format i save it in single column that i can use query to extract correct information.
for e.g.;
i was thinking to concatinate both fields like
col4= ABengineBA + ABBToyotaBBA
and in search i use
SELECT

TBL.col4
FROM

TBL
INNER JOIN

CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABBToyotaBBA"') TBL1
ON

TBL.col1=TBL1.[key]
Result = 1 row

But it don't work in following scenario
col4= ABengineBA + ABBCorola ToyotaBBA

SELECT

TBL.col4
FROM

TBL
INNER JOIN

CONTAINSTABLE(TBL,col4,' "ABengineBA" AND "ABB*ToyotaBBA"') TBL1
ON

TBL.col1=TBL1.[key]

Result=0 Row
Any idea how i can write second query to get result?

SQL Server 2000 - Issue W/ UPDATE - Single Row Update Returns 2 Different Messages

Nov 11, 2007

I am hoping someone can shed light on this odd behavior I am seeing running a simple UPDATE statement on a table in SQL Server 2000. I have 2 tables - call them Table1 and Table2 for now (among many) that need to have certain columns updated as part of a single transaction process. Each of the tables has many columns. I have purposely limited the target column for updating to only ONE of the columns in trying to isolate the issue. In one case the UPDATE runs fine against Table1... at runtime in code and as a manual query when run in QueryAnalyzer or in the Query window of SSManagementStudio - either way it works fine.
However, when I run the UPDATE statement against Table2 - at runtime I get rowsaffected = 0 which of course forces the code to throw an Exception (logically). When I take out the SQL stmt and run it manually in Query Analyzer, it runs BUT this is the output seen in the results pane...
(0 row(s) affected)
(1 row(s) affected)
How does on get 2 answers for one query like this...I have never seen such behavior and it is a real frustration ... makes no sense. There is only ONE row in the table that contains the key field passed in and it is the same key field value on the other table Table1 where the SQL returns only ONE message (the one you expect)
(1 row(s) affected)
If anyone has any ideas where to look next, I'd appreciate it.
Thanks

SQLCE V3.5: Single SDF With Multiple Tables Or Multiple SDFs With Fewer Tables

Mar 21, 2008

Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:

1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.

1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.

1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.

I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.

Thanks in advance for any help/suggestions,
Bob

SQL Server 2008 :: How To Update Multiple Column With Multiple Condition

Feb 25, 2015

I need to update multiple columns in a table with multiple condition.

For example, this is my Query

update Table1
set weight= d.weight,
stateweight=d.stateweight,
overallweight=d.overallweight
from
(select * from table2)d
where table1.state=d.state and
table1.month=d.month and
table1.year=d.year

If table matches all the three column (State,month,year), it should update only weight column and if it matches(state ,year) it should update only the stateweight column and if it matches(year) it should update only the overallweight column

I can't write an update query for each condition separately because its a huge select

Bcp Single CPU Vs Multiple CPU

Oct 20, 2001

I'm doing a BCP of a large table 37 million rows. On a single CPU server, SQL 7, sp 3, with 512 meg of RAM, this job runs in about 3 hours. On a 8 way server with 4 Gig of RAM, SQL 7 Enterprise, this job runs 12 hours and is only a third done. The single CPU machine is running one RAID 5 set while the 8 way server is running 4 RAID 5 sets with the database spread out over two of them.

Is there something obvious that a single CPU box would run this much faster?

Single Or Multiple DB For Different Systems?

Jun 6, 2008

Hi everyone,

Im having a hard time deciding what approach should I take. The scenario is this: I have developed various systems (inventory, HR, accounting, etc.). All this systems are (and should be) tightly integrated with one another. At present, for all these systems, i've used a single DB prefixing the tables with the systems name (eg. Inventory.Items).

My question is: did I did the right (and practical) thing? Or should I create a DB for each system to organize them? The problem with multiple DBs is some system uses the other system's table(s). Example, if i created a separate DB for accounting, and a separated DB for inventory, and another for HR, how am I going to relate inventory and HR's accounts to the accounting DB's table? I want a single instance for each table; I don't want to create another account table for inventory or HR so I can enforce integrity. And if different DBs, is there a performance impact on this?

Or is there another way? My concern is performance and manageability. Please help. Thanks!

Single Or Multiple Services

Aug 31, 2007

I have 2 systems that will send data to each other. Each system will originate a particular set of messages, there will be no overlap. This scenario has transaction data going to a reporting system and management operations going back to the transactional system. It is semi-related data.

I have two patterns in mind, a combined stream of all messages or 2 streams of segregated messages.

A. A single service on each instance would originate a set of messages, process the responses, and receive the other instance's messages. The responses and original message from the other system would mix on the same Q. The activation procs would have to handle all message types. The same infrastructure (message types, contracts, Qs, activation stored procs) would be created on both systems. Although, distinct service names and ports would be used on each instance.

B. Two services and two Qs. 1 service would originate a set of messages, process the responses. The other service would process messages from the other system. The responses and original message from the other system would be on the separate Qs. There would be 2 infrastructures created. There could be separate activation stored procs.

There is just one message type and message validation is only WELL_FORMED_XML.

Which is pattern is better for management and performance? Should I create 1 service or 2 on each instance? Either way should work about as well as the other? 2 services are twice as complex to set up. Separation is not necessary, but I like the idea. 1 service will send many more messages (>10x) than the other. Any thoughts?

Single Row Into Multiple Rows

May 8, 2008

Hi All,

We've a table as in the following format:

PK_Column1
PK_Column2
Issue_Date1
Issue_Amount1
Issue_Category1
Issue_Reject1
Issue_Date2
Issue_Amount2
Issue_Category2
Issue_Reject2

We need to divide it into two new tables as follows:

UniqueID
PK_Column1
PK_Column2
And

UniqueID
PK_Column1
PK_Column2
Sequence_ID
Issue_Date
Issue_Amount
Issue_Category
Issue_Reject

Unique1

1
Issue_Date1
Issue_Amount1
Issue_Category1
Issue_Reject1

Unique2

2
Issue_Date2
Issue_Amount2
Issue_Category2

Unique3

1
xx

xx

Unique4

2
xx

xx

Unique5

3
xx

4

xx

There will be one UniqueID for each row.
We'll get the uniqueID and PK1 and PK2 in a file.
Imp: We need to generate the Sequence_Id depending on number of Issue_dates or Issue_amounts or Issue_Categories or Issue_Rejects as in the above table.

Can we do this without using cursors?
This is going to be one time process.

Any ideas are appreciated.

Thanks,
Siva.
