T-SQL (SS2K8) :: Reading A Control Table - Avoid Using A Cursor

Jan 21, 2015

I am trying to think of a way to read a control table, build the SQL statement for each line, and then execute them all, without using a cursor.

To make it simple... control table would look like this:

CREATE TABLE [dbo].[Control_Table](
[Server_Name] [varchar](50) NOT NULL,
[Database_Name] [varchar](255) NOT NULL,
CONSTRAINT [PK_Control_Table] PRIMARY KEY CLUSTERED

[Code] ....

So if we then load:

insert into zt_Planning_Models_Plant_Include_Control_Table
values ('r2d2','planing1'), ('r2d2','planing7'), ('deathstar','planing3')

Then you would build a SQL script that would end up looking like the following (note all the columns are the same):

insert into master_models
Select * from r2d2.planning1.dbo.models
insert into master_models
select * from r2d2.planning7.dbo.models
insert into master_models
Select * from deathstar.planning3.dbo.models

Trying To Avoid A Cursor...

Jan 13, 2006

Happy new year to all! Now a question...

I added a new column to StagePayments table - Activity - which is supposed to end up being the same as the JobActivityID from the JobActivities table. Basically, I need to get JobActivities (JA) info and put it in the StagePayment (SP) column. Problem is there are duplicate JA/Descriptions and SP/Activities, so what I need is to take the first sequence SP/Activity and grab the first JA/JobActivityID that matches for a particular JobID. Then get the next one of each and so on and so on...

way too basic as I get this error...

I know somehow I have to get the duplicate Activities in the same sequence as the Descriptions, but that's where I'm stuck?!?

If anyone is able to offer suggestions on how to get this to update correctly, I'd be very happy to hear about it!
Thanks in advance!

Would Like To Avoid Cursor, Please Help

Sep 28, 2006

Hi,

I need to query a database for a recordset and insert this into another database row-by-row.

For each record I want to provide a time of insert, but for each insert this time has to be incremented by 1, the time format is HH:MM:SS.0000 so for each inserted record the last decimal point would increment by 1.

Can I do this without a cursor ?

Any additional info I will provide gladly.

Thanks!

I Want To Avoid Using A Cursor, Please!

Jul 23, 2005

Application is a Work Tracking/Timesheet database.The increments of work are stored in the TimesheetItem table. Thiscontains, inter alia, the Work Code, the Start and the Duration thatthe employee spent that day on a particular project.Some employees in the Network Support Department don't complete astandard 7.5 hour day for various reasons, so for every Network Supportperson I need to update these particular days with an amount to bringthe total day's hours to 7.5.This SQL will get me a list of all TimesheetItem records for thepersonnel concerned.SELECTTimesheetItem.TypeID,[Work].WorkCode,TimesheetItem.Start AS Start,SUM(CAST(TimesheetItem.DurationMins AS float) / 60) AS HoursFROMTimesheetItem LEFT OUTER JOIN[Work] ON TimesheetItem.WorkID = [Work].WorkIDWHERE(TimesheetItem.EmployeeID IN(SELECT EmployeeID FROM Employee WHERE DepartmentID = 2))GROUP BYTimesheetItem.TypeID, TimesheetItem.Start, [Work].WorkCodeHAVING(TimesheetItem.Start >= @FromDate) AND (TimesheetItem.Start <= @ToDate)ORDER BYTimesheetItem.StartWhat I need is to group these records by EmployeeID where theaccumulated hours per day are < 7.5, so that I can then insert anincrement to make up the difference.I'm writing this from home and I don't have access to the tables toprovide a script, but there's nothing untoward there.Hope someone can help!ThanksEdward

How Can Avoid Displaying Data Using A Cursor ??

Oct 16, 1998

I defined a stored procedure with a cursor inside for updating data.
When I call it from an MSAccess client, it fails.
When I execute it directly in a ISQL/w windows, it doesn`t fail but it displays me the data (wich is the reason for failing from MSAccess).
Do somebody know if I could do it without displaying data in the screen ??

SQL Server 2012 :: Using WHILE To Avoid Cursor Under Certain Conditions

Mar 20, 2015

I need to use WHILE to avoid Cursor under certains conditions.

My SELECT statement is:

SELECT ref, ano, numberofyears ,nreint, naoreint,degress,
tabela, tax, taxamaxima,[evactual],
[evaldepact],[ereintact],nrregbt,[taxAmtAno]
FROM deprec
ORDER BY [ref] ASC

numberofyears= 100 /tax for exemple for a good where lifecycle is 4 years ,ex:
Tax = 25% Then 100/25 = 4 years

I see this WHILE script, but i need to run :

1. for each REF + Until years < 4 in this exemple, because i have goods years depend on Percent.

the WHILE script i see is:

DECLARE @table1 TABLE (Id int not null primary key identity(1,1), col1 int )
INSERT into @table1 (col1) SELECT col1 FROM table2
SET @num_rows=@@ROWCOUNT

SET @cnt=0
WHILE @cnt<@num_rows

[Code] .....

My doubt is how to make the LOOP for each REF until Year < 4 (like my example)

T-SQL (SS2K8) :: Cursor From Variable - Procedural Loop

So effectively i have a table of names of stored procedures. I now have a store proc that loops around these procs and runs each one in order.

Now i am thinking i would like to be able to set the table it loops around in a variable at the start - is it possible to do this? So effectively use a tablename in a variable to use in the sql to define a cursor?

T-SQL (SS2K8) :: Fetch Next From Cursor Returns Multiple Rows?

Aug 9, 2014

I don't understand using a dynamic cursor.

Summary
* The fetch next statement returns multiple rows when using a dynamic cursor on the sys.dm_db_partition_stats.
* As far as I know a fetch-next-statement always returns a single row?
* Using a static cursor works as aspected.
* Works on production OLTP as well as on a local SQL server instance.

Now the Skript to reproduce the whole thing.

create database objects

-- create the partition function
create partition function fnTestPartition01( smallint )
as range right for values ( 1, 2, 3, 4, 5, 6, 7, 8 , 9, 10 ) ;

[Code]....

Why does the fetch statement return more than 1 row? It returns the whole result of the select-statement. When using a STATIC cursors instead I get the first row of the cursor as I would expect. Selecting a "normal" user table using a dynamic cursor I get the first row only, again as expected.

Index Help To Avoid Table Scan

Sep 29, 2006

I have following query to delete the data from fact history table based on fact table. logid, level and post_date uniquely identify the rows on both fact and history table. I want to create indexes on the joined columns.I tried with clustered index (logid, level and post_date) it gives clustered index scan. I also tried with non clustered indexes on each column (logid, level and post_date) but still getting table scan.
Do you have any suggestion on which columns should I create proper indexes to avoid table or index scan? There are about 6 million rows on each table.


DELETE xbar_fact_history
FROM xbar_fact_history AS a
INNER JOIN xbar_fact AS b
ON a.logid = b.logid
AND a.level = b.level
AND a.post_date = b.post_date
AND a.check_CheckSum <> BINARY_CHECKSUM(b.out_mins,b.nor_hrs,b.pdi_call)

How Can I Avoid Table Lock In SQL2000?

To any and all;I have a very large table (16Mil+ records), for which I want to deleteabout 8 Million records. There are a few indexes on this table.Is there a way that I can run either a query or a series of queriesthat will run against each record and delete based on criteria (date)?If I do a single DELETE query, it will take forever, lock the table,and my app that runs against it will stop INSERTING, which is bad.If I do a cursor, I think it locks the table also, so that won't do,right?Any help would be appreciated.Glenn DekhayserContentcatcher.com

select @i, '1.' + cast(@i as varchar(5))
set @i = @i - 1
end

insert into dbo.test2
select 1, '2.1' union all
select 2, '2.2'
go

-- create view
create view dbo.vw_Test
as
select1 as QueryID,
TestName
fromdbo.Test1
union all
select2 as QueryID,
TestName
fromdbo.Test2;
go


-- this works as i want, only scans table dbo.Test2
select *
fromdbo.vw_Test
whereQueryId = 2

-- joining to a table triggers scan of both tables in view:
declare @table table (QueryID int)
insert into @table
select 2;

selectvt.TestName
fromdbo.vw_Test vt
join@table t on
vt.QueryID = t.QueryID



Using the showplan I can see why the optimizer ends up scanning all tables, but maybe there is a way to force it to use the QueryID param evaluation earlier in the filtering.

Permission On View. Is There Way To Avoid Granting Persmission On The Underlying Table?

Jul 13, 2007

I want to grant access on the below view for an end user so that he connect to our SQL server and retrieve data. The view looks like the below


CREATE VIEW DB1.[dbo].[View1]
AS
-- For brevity, I made it as simple statement.
SELECT *
From DB2.dbo.table2
GO

For the above view, it looks like I have to grant select and connect permission for the DB1. [dbo].[View1] as well as DB2.dbo.table2.

1. Is my understanding correct?

2. I want the user to access only DB1. [dbo].[View1] and not the underlying tables. Is there a way to grant access only on the view and execute the statement on a different security context so that the user can€™t access DB2.dbo.table2 directly?

3. When the user uses SQL Server Management Studio to connect to SQL server, he is able to connect and select DB2.dbo.table2 directly. Is there any way to restrict user from viewing and executing select statement on DB2 database from SQL Server Management Studio

Thanks in advance for your help

With regards
Ganesh

Reading And Writing To Same Table

Feb 16, 2008

I need to select all the records in a table, loop through them one by one, calculating some new field data, and then write the new data back to the same table. Here is the basic structure of what I've come up with:<CODE>SqlCmd = SqlConn.CreateCommandSqlStatement = "SELECT ProductID, Name FROM tblProducts"SqlCmd.CommandText = SqlStatementSqlRdr = SqlCmd.ExecuteReaderIf SqlRdr.HasRows Then  While SqlRdr.Read    If SqlRdr.FieldCount > 0 Then      ...      SqlWriteCmd = SqlConn.CreateCommand      SqlStatement = "UPDATE tblProducts SET Name = '" & NewName & "' WHERE ProductID = " & CStr(ProductID)      SqlWriteCmd.CommandText = SqlStatement      SqlWriteCmd.ExecuteNonQuery()      SqlWriteCmd = Nothing    End If  End WhileEnd IfSqlRdr.Close()SqlCmd = Nothing </CODE>I get an error that tells me to close out the Reader before trying to execute the write query. But I can't close it out for the loop to work properly. So I assume that there must be another way to do this simple task, but I'm so new to all of this that I need some help! Thanks!
