works fine but I want to take @list and use it to update my customers table. here is the full code.

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)

What is the purpose of creating table variable and inserting data into it and selecting from table variable inside of stored proc?
Why can't the stored proc just have select statement instead of creating table variable?

To see where is the problem I am trying to count rows in the database.First I create a table A with 2 columns namely tablename, rowbefore and rowafter and I insert records in it as below.
INSERT INTO A
SELECT TableName = o.name, '', Rows = max(i.rows) FROM sysobjects o
INNER JOIN sysindexes i ON o.id = i.id
WHERE xtype = 'u' AND OBJECTPROPERTY(o.id,N'IsUserTable') = 1
GROUP BY o.name
ORDER BY o.name
Then I update rowbefore with rowafter as below.
UPDATE A SET rowbefore = rowafter
Now I launch my application with update records in the database.Then I am trying to update rowafter with new records as below.
UPDATE A
SET rowafter = (SELECT max(sysindexes.rows) FROM sysobjects
INNER JOIN sysindexes ON sysobjects.id = sysindexes.id
WHERE xtype = 'u' AND OBJECTPROPERTY(sysobjects.id,N'IsUserTable') = 1 AND A.tablename = sysobjects.name)
Does this update really update my column rowafter or not?

I have some stored procedures that do updates using table aliases, like this:
UPDATE TableAlias
SET ColVal = 1
FROM RealTable AS TableAlias
WHERE TableAlias.ColVal <> 1
This allows me to include joins and stuff in the update (not shown) and make it all more readable for me.
It all works fine, and the SSMS parser says it's fine. But I also have another script which looks at sys.sql_expression_dependencies and sys.objects to find stored procedures with invalid object references (see below), and it's understandably saying that all of the above type stored procedures have invalid references.
SELECT
OBJECT_NAME(DEP.referencing_id) AS referencing_name,
DEP.referenced_entity_name
FROM sys.sql_expression_dependencies AS DEP
WHERE
-- Only validate local references:
(
DEP.referenced_database_name = DB_NAME()
[Code] ....
So I have a couple questions.
1. Is the UPDATE syntax I'm using kosher?
2. Can you recommend any updates to my stored procedure validation script that will better accommodate table aliases like mine?

I have a table with 8 columns, I need to update data in multiple columns on this table, this table contains 1 million records, having single update was taking time so I broke the single update into multiple update statements and running multiple update statements in parallel, Each update statement updates different column.
This approach is working fine but I am getting the deadlock error.
Transaction (Process ID 65) was deadlocked on lock | communication buffer resources with another process and has been chosen as the deadlock victim. Rerun the transaction.
I tried with various lock hints but no success.

I am trying to run an update statement against a vendor's database that houses HR information. If I run a regular select statement against the database with the following query, it returns without error:
SELECT "QUDDAT_DATA"."QUDDAT-INT", "NAME"."INTERNET-ADDRESS", "QUDDAT_DATA"."QUDFLD-FIELD-ID", "QUDDAT_DATA"."QUDTBL-TABLE-ID"

I am assuming I am receiving this error because it doesn't know where to find QUDDAT-INT? How can I fix that?

In a stored procedure I dynamically create a temp table by selecting the name of Applications from a regular table. Then I add a date column and add the last 12 months. See attachment.
So far so good. Now I want to update the data in columns by querying another regular table. Normally it would be something like:
UPDATE ##TempTable
SET [columName] = (SELECT SUM(columName)
FROM RegularTable
WHERE FORMAT(RegularTable.Date,'MM/yyyy') = FORMAT(##TempMonths.x,'MM/yyyy'))
However, since I don't know what the name of the columns are at any given time, I need to do this dynamically.
how can I get the column names of a Temp table dynamically while doing an Update?

Our system runs a SQL Server 2012 DB, it has a table (table_a) which has over 10M records. Our system have to receive data file from previous system daily which contains approximate 3M updated or new records for table_a. My job is to update table_a with the new data.
The initial solution is:
1 Create a table (table_b) which structur is as the same as table_a
2 Use BCP to import updated records into table_b
3 Remove outdated data in table_a:
delete from table_a inner join table_b on table_a.key_fileds = table_b.key_fields
4 Append updated or new data into table_a:
insert into table_a select * from table_b
As the test result, this solution is very inefficient. Step 3 costs several hours, e.g. How can I improve it?

I have a stored proc that contains an update which utilizes a case statement to populate values in a particular column in a table, based on values found in other columns within the same table. The existing update looks like this (object names and values have been changed to protect the innocent):
UPDATE dbo.target_table
set target_column =
case
when source_column_1= 'ABC'then 'XYZ'
when source_column_2= '123'then 'PDQ'
[Code] ....
The powers that be would like to replace this case statement with some sort of table-driven structure, so that the mapping rules defined above can be maintained in the database by the business owner, rather than having it embedded in code and thus requiring developer intervention to perform changes/additions to the rules.
The rules defined in the case statement are in a pre-defined sequence which reflects the order of precedence in which the rules are to be applied (in other words, if a matching value in source_column_1 is found, this trumps a conflicting matching value in source_column_2, etc). A case statement handles this nicely, of course, because the case statement will stop when it finds the first "hit" amongst the WHEN clauses, testing each in the order in which they are coded in the proc logic.
What I'm struggling with is how to replicate this using a lookup table of some sort and joins from the target table to the lookup to replace the above case statement. I'm thinking that I would need a lookup table that has column name/value pairings, with a sequence number on each row that designates the row's placement in the precedence hierarchy. I'd then join to the lookup table somehow based on column names and values and return the match with the lowest sequence number, or something to that effect.

The objective is to identify orders where an order fee has been applied incorrectly. I have multiple orders per customer, my table contains an orderID and a customerID. Currently if the customer places additional orders before the previous orders have been closed/cancelled, then additional fees are being applied.
Let's say I'm comparing order #1 to order #2. I need to identify these rows where the following is true:-
The CustID is the same.
Order #2 has a more recent order date.
Order #2 has a FeeDate Before the CancelledDate of Order #1 (or Order #1 has no cancellation date).
So in the table the orderID:2835692 of CustID: 24643 has a valid order fee. But all the subsequently placed orders have fees which were applied before the first order was cancelled and so I want to update the FeeInvalid column with a 'Y'. The first fee will always be valid.
I think I understand why the code I am trying doesn't achieve the result I want but I can't figure out how to write it correctly. Below is one example of code I've tried and also code to create the table and insert some test data.
update t1
SET FeeInvalid = 'Y'
FROM MockData t1 Join MockData t2 on t1.CustID = t2.CustID
WHERE t1.CustID = t2.CustID
AND t2.OrderDate > t1.OrderDate
AND t2.FeeDate > t1.CancelledDate
CREATE TABLE [dbo].[MockData](
[OrderID] [float] NULL,

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,

I have run into a perplexing issue with how to UPDATE some rows in my table correctly.I have a Appointment table which has Appointment Times and a Appointment Names. However the Name is only showing on the Appt start Time line. I need it to show for its duration. So for example in my DDL Morning Appt only shows on at 8:00 I need it to show one each line until the next Appt Starts and so on. In this case Morning Appt should show at 8:00,8:15, 8:30.
CREATE TABLE #TEST ( ApptTime TIME, ApptName VARCHAR (20), DURATION TINYINT)
INSERT INTO #TEST VALUES ('8:00', 'Morning Appt', 45), ('8:15', NULL, NULL),('8:30', NULL,NULL),('8:45', 'Brunch Appt', 45),('9:00', NULL,NULL),('9:15', NULL,NULL),
('9:30', 'Afternoon Appt', 30),('9:45', NULL,NULL),('10:00', NULL,NULL).

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.

I have a table named 'DepartmentItem' which is designed with hierarchy structure. The column 'ParentId' from table DepartmentItem indicates parent-child relationship and department root among records. I have written and run a user-defined function I use recursive approach, but the function runs slowly.
My question: is there a better way to query that hierarchy table instead of using recursive?
** The current user-defined function that is written using recursive:
CREATE FUNCTION dbo.fnGetDepartmentTree
(
@departmentItemId int
)
RETURNS TABLE
AS
RETURN
with DepartmentItemTree(DepartmentItemId , DepartmentItemTypeId , ParentId, ItemOrder, Level)
[code].....
** And definition of table 'DepartmentItem' :
DepartmentItemId int IDENTITY(1,1) NOT NULL,
ParentId int NULL, -- Each department root starts when this column is NULL or the current row is department root. If it is not NULL then the current row has ParentId whose record has DepartmentItemId = ParentId of the current row (see more below)
IsActive bit NOT NULL DEFAULT ((1)),
