Update Table Variable From Another Table

Sep 10, 2007

I need to update a table variable with a sum from another table. Something like this:


DECLARE @MyTableVariable Table

(

Location varchar(10),

ItemNumber Varchar(10)

Amount money,

Quantity int

)



UPDATE @MyTableVariable

SET Quantity =( SELECT SUM(Quantity)

FROM myTable

WHERE @MyTableVariable.[Location] = myTable.[Location]

and

@MyTableVariable.[ItemNumber] = myTable.[ItemNumber] )

The where clause does not work though. Is there a way to do this?

SQL Server 2012 :: Update Table From Variable Table Column?

Oct 6, 2014

I am trying to use a stored procedure to update a column in a sql table using the value from a variable table I getting errors because my syntax is not correct. I think table aliases are not allowed in UPDATE statements.

This is my statement:

UPDATE [dbo].[sessions_teams] stc
SET stc.[Talks] = fmt.found_talks_type
FROM @Find_Missing_Talks fmt
WHERE stc.sessionid IN (SELECT sessionid FROM @Find_Missing_Talks)
AND stc.coupleid IN (SELECT coupleid FROM @Find_Missing_Talks)

UPdate Table Variable

Apr 6, 2008

Hi all,

Hopefully an easy question to answer.

I'm looking to update a field in a table variable with the results from a SQL query. The SQL query howver needs to use the ID filed of the table variable which has already beeen populated.

Effectively, for each ID in the table variable run the query using that ID field and then pass the scalar result into another column.

I'm having a bit of trouble doing this. Can anyone help?

Thanks in advance,

G

Table Variable With Update Slow

May 30, 2007

Hi



I have an update query that joins with 2 table variables. this update updates about 50,000 rows in a table.



update table1

from @table2 t2

inner join @table3 t3

on t2.id = t3.id

where table1.id = t2.id



the problem is that sometimes this update takes forever. If I replace the table variable with regular tables, it only takes about 11 seconds.



I am not sure what the problem is. Could this be a problem with the tempdb. What should I be looking for in the tempdb that might cause a problem.

Power Pivot :: Temp Table Or Table Variable In Query (not Stored Procedure)?

Jul 19, 2012

I don't know if it's a local issue but I can't use temp table or table variable in a PP query (so not in a stored procedure).

Environment: W7 enterprise desktop 32 + Office 2012 32 + PowerPivot 2012 32

Simple example:
    declare @tTable(col1 int)
    insert into @tTable(col1) values (1)
    select * from @tTable

Works perfectly in SQL Server Management Studio and the database connection is OK to as I may generate PP table using complex (or simple) queries without difficulty.

But when trying to get this same result in a PP table I get an error, idem when replacing table variable by a temporary table.

Message: OLE DB or ODBC error. .... The current operation was cancelled because another operation the the transaction failed.

Table Variable Versus #Temp Table

Jan 17, 2008

In a previous post "Could #TempTable within SP cause lock on tempdb?" http://forums.microsoft.com/msdn/showpost.aspx?postid=2691763&siteid=1

It was obvious that we have to limit the use of #Temp table to a minimum. Let assume that some of the temp tables are really difficult to replace and we have to live with them.

Would it be easier on tempdb if the #TempTable is replaced by a table variable? Or do they all end up in tempdb?

Thanks in advance for any help.

Table-valued Function Run Once For Each Row In A Table Variable.

Mar 19, 2008

I have a stored produre. Inside this stored procedure I have table variable with one column. Once the table variable is populated with rows, I would like to pass each value in the table, into a table-valued function. The table-valued function may return any number of rows. I would like all the rows the TVF returns to be returned from the stored procedure as a single result set. I would also like to do this without defining a table variable to hold the results of the table-value function.




Code Snippet

declare @IdTable table
(
EmployeeId nvarchar( 16 ) not null
)
insert into @IdTable
select EmployeeNumber from Employees

/*
I need to run this query for every EmployeeId value in @IdTable and return the results from the stored proc as a single result set.
*/
select * from fn_GetEmployeeById( EmployeeId )







Any help is very much appreciated.

Stored Procedure That Fetch Each Row Of A Table And Update Rows In Another Table

Jan 31, 2006

I am working with the following two tables:

Category(NewID,OldID)
Link(CategoryID,BusinessID)

All fields are of Integer Type.

I need to write a stored procedure in sql 2000 which works as follows:

Select all the NewID and OldID from the Category Table
(SELECT NewID,OldID FROM Category)

Then for each rows fetched from last query, execute a update query in the Link table.

For Example,

Let @NID be the NewID for each rows and @OID be the OldID for each rows.
Then the query for each row should be..

UPDATE Link SET CategoryID=@CID WHERE CategoryID=@OID

Please help me with the code.

Thanks,

SQL Server 2008 :: Non Blank / Non Null Value From Table To Update Same Table

Mar 13, 2015

Here is the sample data for table.

create table #sample (emp varchar(max),data1 varchar(max),data2 varchar(max), Rdate date)
insert into #sample (emp,data1,data2,rdate)
values('john','','',getdate())

insert into #sample (emp,data1,data2,rdate)
values('tony','','',getdate())

[Code] ...

I need to update the data1, data2 from yesterday or before but they should be non blank and non null and update to todays data.

It means, I can't update to 2015-03-12 values to 2015-03-13, as they are blanks or nulls.

So I need to go 2015-03-11 and check the values, if they are not blank , i need to update with todays values.

Before the update :

empdata1data2Rdate
john3/13/2015
tony3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015
tonyab3/11/2015

After the update:

empdata1data2Rdate
johncd3/13/2015
tonyab3/13/2015
john3/12/2015
tony3/12/2015
johncd3/11/2015

Update Temp Table With Stored Procedure Joined With Table

Hello

Is it possible to insert data into a temp table with data returned from a stored procedure joined with data from another table?

insert #MyTempTable

exec [dbo].[MyStoredProcedure] @Par1, @Par2, @Par3

JOIN dbo.OtherTable...

I'm missing something before the JOIN command. The temp table needs to know which fields need be updated.

I just can't figure it out

Transact SQL :: Update Table Based On Available Date Range In Same Table

Dec 2, 2015

I would like to update the flag of the promotion ID should the promotion ID date range overlap with Promotion ID(All) Date Range. The general logic is as below.

Update TableName
SET PromotionID Flag = 1 AND Reason = 'Overlap with row ID(Overlap row ID number)'
Where EACH ROW(Except with Promotion ID ALL) Date Range Overlap with ROW(with promotion ID ALL) Date range

Note: ROW is Partition By ColumnA,ColumnB

TableName: PromotionList

ID PromotionID StartDate EndDate ColumnA ColumnB Flag Reason
1 1 2015-04-05 2015-05-28 NULL NULL 0 NULL
2 1 2015-04-05 2015-04-23 2 3 0 NULL
3 2 2015-05-04 2015-07-07 2 3 0 NULL
4 ALL 2015-04-05 2015-04-28 NULL NULL 0 NULL
5 ALL 2015-07-06 2015-07-10 2 3 0 NULL
6 1 2015-02-03 2015-03-03 NULL NULL 0 NULL

Expected outcome after performing update on the table

ID PromotionID StartDate EndDate ColumnA ColumnB Flag Reason
1 1 2015-04-05 2015-05-28 NULL NULL 1 Overlap with row ID 4
2 1 2015-04-05 2015-04-23 2 3 0 NULL

I have a table called ADSCHL which contains the school_code as Primary key and other two table as

RGDEGR(common field as SCHOOl_code) and RGENRl( Original_school_code) which are refrencing the ADSCHL. if a school_code will be updated both the table RGDEGR (school_code) and RGERNL ( original_schoolcode) has to be updated as well. I have been provided a new data that i have imported to SQL server using SSIS with table name as TESTCEP which has a column name school_code. I have been assigned a task to update the old school_code vale ( ADSCHL) with new school_code ( TESTCEP) and make sure the changes happen across all 3 tables.

I tried using Merge Update function not sure if this is going to work.

My question is, how to insert the values from variable into a table (table variable or temp table or CTE).OR Is there any way to parse the multiple values into a table. like if we pass multiple values into a parameter. those should go into a table as rows.
