In Access, if I want to update one table with information from another,
all I need to do is to create an Update query with the two tables, link
the primary keys and reference the source table(s)/column(s) with the
destination table(s)/column(s). How do I achieve the same thing in SQL?

I'm new to adp w/ sql server but I have to use it on a project i'mdoing...One of the MUSTS for this project is the ability to update a 00 - 09text value with the appropriate text description from another table...Easy as pie in .mdb. Of course In the stored procedure it barks at meand tells me that an update query can only have one table.. ouch thathurts...I'm currently reading on the subject but this group has been veryhelpful in the past.....I found this link...http://www.sqlservercentral.com/col...stheeasyway.aspUnfortunetly I'm using MSDE not Enterprise so I don't think I can usethe query analyser.. But I tryed it in my Access ADP anywayit barked at me..I tried to go from this....SELECT dbo.LU_SEX.SEX_CODE, dbo.TEST.DEFECTS_DP1FROM dbo.TEST INNER JOINdbo.LU_SEX ON dbo.TEST.SEX_DP1 =dbo.LU_SEX.SEX_DECTo this...UPDATE dbo.TEST.SEX_DP1SET dbo.TEST.SEX_DP1 = dbo.LU_SEX.SEX_CODEFROM dbo.LU_SEX INNER JOINdbo.TEST ON dbo.LU_SEX.SEX_DEC =dbo.TEST.SEX_DP1Maybe I need a good book on this?Thanks,Charles

My scenario:
I have a master securities table which has 7 fields. As a part of the daily process I am uploading flat files into database tables. The flat files contains the master(static) security data as well as the analytics(transaction) data. I need to
1) separate the master (static) data from the flat files,
2) check whether that data is present in the master table, if not then insert that data into the master table
3) If data present then move that existing record to an history table and then update the main master table.
All the 7 fields need to be checked to uniquely identify a single record in the master table.
How can this be done? Whether we can us a combination of data flow items or write a sql procedure to do all this.
Thanks in advance for your help.

Oracle and MS drivers do not support parameterized queries, so update table set column=? where primarykey=? does not work for Oracle.
Anyone knows how to update an Oracle table through SSIS?
Thanks!

Is there any way to use a graphical designer to build your insert & update SQL statements in Enterprise manager? I mean Access has an EASY way to build them, surely SQL does too?
I would just build them in Access and copy the SQL, but then I'm stuck replacing all the "dbo_" with "dbo." and other little nuances.
I have a page that will require several hundred update queries to be sent to the database. How much of a performance increase will i get by joining them all into one statement and sending them as a batch instead of running them one by one?
Thanks.
Hi,
Trying to update a single value within a table, thus eliminating nulls. Another words, if the value is NULL update it with the next preceeding non-null value. In this example, 1 should be CO, 2 should be CO, 6 should be CO, 8 should be TT, and 10 should be TT.
For example,
1 NULL
2 NULL
3 CO
4 CO
5 CO
6 NULL
7 TT
8 NULL
9 TT
10 NULL
Any ideas? Thanks.
Help, please. I am trying to update atable with this structre:CREATE TABLE Queue (PropID int, EffDate smalldatetime,TxnAmt int)INSERT Queue (PropID) SELECT 1INSERT Queue (PropID) SELECT 2INSERT Queue (PropID) SELECT 3....from this table...CREATE TABLE Txns (PropID int, TxnDate smalldatetime,TxnType char(1), TxnAmt int)INSERT Txns SELECT 1 '20000201', 'B', 100000INSERT Txns SELECT 1 '20020515', 'B', 110000INSERT Txns SELECT 1 '20020515', 'A', 120000INSERT Txns SELECT 1 '20020615', 'c', 130000....only certain txn types are okay, and they have an orderof preference...CREATE TABLE GoodTxnTypes (GoodTxnType char(1), Pref)INSERT GoodTxnTypes SELECT 'A', 1INSERT GoodTxnTypes SELECT 'B', 2The idea is to fill in the NULL fields in the Queue table,according to a rule -- the transaction must be the latesttransaction within a date window, it must be one of the goodtxn types, and if there are two txns on that date, choosethe txn by the preferred txn type (A is preferred over B,according to the field Pref).If the time window were 20020101 to 20030101, the txnselected to update the Queue table would be this one:INSERT Txns SELECT 1 '20020515', 'A', 120000 -- there aretwo in the time window that are type A or B; they areboth on the same day, so the 'A' is preferred.If the time window were 20000101 to 20010101, this wouldbe selected because it is the only A or B type txn inthe interval:INSERT Txns SELECT 1 '20000201', 'B', 100000I'm looking for a statement that starts...UPDATE Queue SET EffDate = ...., TxnAmt = .... (EffDate,in this table, is the same as TxnDate in the Txn table).Assume we have @FirstDate and @LastDate available.Help, please. I'm getting stuck with (a) a sub-query tofind the relevant Txn records, and (b) another sub-querywithin that to find the MAX(TxnDate) within the timewindow. Filtering the Txn records on the basis of theGoodTxnTypes table is easy, as is ordering what is returned.But I'm having trouble joining the sub-queries back to theQueue table on the basis of PropId.

I'm writing an application for Windows Mobile 5 / Pocket PC using VB.NET 2005. The database is connected using an instance of SqlCeConnection and updated by an SqlCeCommand.
The application can perform select queries on data originally entered into the database through Visual Studio, or perform update / insert queries at run time. Anything inserted or updated can be returned by a select query whilst the application is running, however, anything I have inserted or updated doesn't appear to be written to the SDF file and hence is not in the database after restarting the application.
Am I missing something that's different between performing queries on an SQL CE database on Pocket PC and an ODBC source in a normal Windows application?
At one of your client sides we have configured Always on with synchronous mode.Also we have schedule rebuild index and update statistics job which runs in night every alternate day. the issue is there are more then 100 sleeping queries which is blocking update statistics job.
I have to stop update statistics job manually once i come to office manually.
Once I have killed blocking sleeping query but then other sleeping query blocked it and so on.
I need to search for such SPs in my database in which the queries for update a table contains where clause which uses non primary key while updating rows in table.
If employee table have empId as primary key and an Update query is using empName in where clause to update employee record then such SP should be listed. so there would be hundreds of tables with their primary key and thousands of SPs in a database. How can I find them where the "where" clause is using some other column than its primary key.
If there is any other hint or query to identify such queries that lock tables, I only found the above few queries that are not using primary key in where clause.

That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

I have a table where table row gets updated multiple times(each column will be filled) based on telephone call in data.
Initially, I have implemented after insert trigger on ROW level thinking that the whole row is inserted into table will all column values at a time. But the issue is all columns are values are not filled at once, but observed that while telephone call in data, there are multiple updates to the row (i.e multiple updates in the sense - column data in row is updated step by step),
I thought to implement after update trigger , but when it comes to the performance will be decreased for each and every hit while row update.
I need to implement after update trigger that should be fired on column level instead of Row level to improve the performance?

Hi,
I wanted to know a query which will create a final result table from a combination of select queries.
The select query is like :
1. select col1 , col2 , null from table1
2. select null , col2 , null from table2
3. select null , null , col3 from table 3.
null are inserted as i wanted a single select query which will merge all the columns from all the tables and finally create a result table.
Thanks in advance.
I was messing around with stored procedures and I was wondering if creating a SP that populates a single table for reporting is a good idea?
I have ~10 queries that I have to currently run manually and was hoping to drop them into a physical table and then leverage that single table to pull into excel.
Some of my queries use virtual tables or CTE's, this is to get the aggregate set correctly.
Essentially I am working out of a data warehouse and would like to eventually get all my queries in one SP or something similar and then call that query for a insert.
Speaking of which could you create a SP that has several selects than with that output drops the records into a single table by using an insert into query so the data from the all the queries would line up into the right columns?
I am trying to insert the queries in a table such as the following, not able to insert it.
create table test (txt Varchar(200))
insert into test values('select *from master.dbo.sysprocesses WHERE status NOT IN('sleeping','background')')
I have 3 queries pulling from the same table, trying to define a count on each criteria. I have the data pulling, but the data is in multiple rows. I want the data in one row with all the counts in each separate columns. Also I need to setup a flag if a client purchased and order within 30 days from their last purchase.
I am doing this select for each credit card, check and cash purchases. I do not know how to setup a flag where the client may have ordered and paid by check or cash after 30 days from a credit card purchase. Is this something that can be done?
select
clientnumber,count(distinct clientnumber) as cccnt,
0 as ckcnt, 0 as cacnt
from dbo.purchases
where orderdate >= 20120101 and orderdate <= 20121231 and
payment_type = 'CC'
group by clientnumber;
OUTPUT currently looks like this:
1234 2 0 0
1234 0 1 0
1234 0 0 4
Is it possible to result in this, along with a flag with the criteria above?:
1234 2 1 4 Y
Hi friends,
when I write multi-table queries which involve two tables which are joined via a bridging table (M:N),
do I just join the tables or do I have to reference the bridging table as well in the queries?

Hi,
I currently have three queries running seperately which I'd like to join up..
However I'm sure it can be done..
Here goes:
I have one table which lists payments made (it stores a PaymentID from another table, a payment amount and an invoiceID)
Therefore there can be several records with the same PaymentID referenceing different invoices (i.e a user paying off several invoices with one payment)
I have one query which lists all of the invoices paid against one payment.
SELECT PaymentID, InvoiceID, PaymentAmount WHERE PaymentID = xxx AND PayType <> 'Credit'
I then have a second query which is ran against each individual invoice which shows the other payments which have been made against this invoice already
SELECT PaymentID, InvoiceID, PaymentAmount WHERE PaymentID <> xxx AND PayType <> 'Credit' AND InvoiceID = XXX
and final I have one query which lists the credits
SELECT PaymentID, InvoiceID, PaymentAmount WHERE PayType = 'Credit' AND InvoiceID = XXX
All of the above lets me see an payment, which invoices have been paid against that payment.. and then for each invoice, any other payment which were made beforehand, and finally any credits against that invoice.
I run these from an ASP page in a loop which is pretty inefficient way of doing it.
I would much prefer to amalgamate the three queries above so I could see what I was paying now, what had already been paid and what was credited against each invoice from a PaymentID.. all in query.
Is that possible?
Thanks

I'm working with a table with about 60 million records. This monster is growing every minute of the day as well, by 200,000 - 300,000 records/day. It's 11 columns wide, and has one index on a datetime column. My task is to create some custom reports based on three of these columns, including the datetime one.
The problem is response time. Any query executed on this table takes forever--anywhere between 30 seconds and 4 minutes. Queries such as this one below, as simple as it is, can take a minute or more:
select
count(dt_date) as Searches
from
SearchRecords
where
datediff(day,getdate(),dt_date)=0
As the table gets larger and large, the response time is going to get worse and worse. Long story short, what are my options to get the speed of queries down to just a few seconds with a table this big? So far the best I can come up with is index any other appropriate columns (of which there is one for sure, maybe two).
I have the following MDX query:
SELECT NON EMPTY {[DateT].[Year].[Year].Members } ON ROWS,
NON EMPTY { [Measures].[Val] } ON COLUMNS FROM [MyDB]
I need to order the data by year, so I tried this query:
SELECT
NON EMPTY { Order ( [DateT].[Year].[Year].Members,Desc) }
ON ROWS,
NON EMPTY { [Measures].[Val] } ON COLUMNS
FROM [MyDB]
But it doesn't work.
Hello. I'm having some difficulty trying to output the results of two seperate queries into the same temporary table.
Does anyone know if it is possible to use the UNION operator to output the results into a temporary table?
Select * From TableA
UNION
Select * From TableB
<---output result to temporary table here--->
Alternatively, is it possible to output the results of two queries in to the same temporary table without the UNION clause?
The following statement fails on the second SELECT INTO due to the fact that #MyTempTable already exists.
Select * INTO #MyTempTable FROM TableA
Select * INTO #MyTempTable FROM TableB
Thanks in advance.
Hi all.
How can I lock table with longtime query?
I would like to pull all the columns from a table where the date column is within 6 months from the max date (i.e. Jul, Aug, Sep, Oct, Nov, & Dec). In addition to that, I would like to pull another column -the summary column - from the same table where the date = max(date) (Dec only).
I have written 2 queries and they produce the correct data. However, I don't know how to combine them into one resultant table. I tried to do a left join and had difficulties dealing with the different where statements from the 2 queries..
Here is query #1:
select investor, full_date, month_end_summary, category, loan_count
from cust_table
where datediff(month,full_date,(select max(full_date) from cust_table)) < 6
group by investor, full_date, month_end_summary, category, loan_count
order by investor, full_date
Here is query #2:
select investor, full_date, month_end_summary
from cust_table
where datediff(month,full_date,(select max(full_date) from cust_table)) =0
order by investor, full_date
Can they be combined into one query to produce one result table??

Hello
I've to write an trigger for the following action
When a entry is done in the table Adoscat79 having in the index field Statut_tiers the valeur 1 and a date in data_cloture for a customer xyz
all the entries in the same table where the no_tiers is the same as the one entered (many entriers) should have those both field updated
statut_tiers to 1
and date_cloture to the same date as entered
the same action has to be done when an update is done and the valeur is set to 1 for the statut_tiers and a date entered in the field date_clture
thank you for your help
I've never done a trigger before
Hello,
I have a table that I want to cache. So, if this is my query "SELECT * FROM myTable" that I create the cache from, how can I filter the data?
I really need to cache the whole table, since there are a myriad of different statements being executed against the table, so just caching a specific query won't do.
I've found the best approach to make a question is writing it in code, so how can I do the following:
SELECT ColNames FROM MyTableWhichShouldNowBeCached WHERE whereColumns=someParams.
ColNames and someParams make up for a variation of about to 120 different queries. I use SQL 2005 express edition with advanced services.
Cheers!
