I'm wondering how/why this query works. Trying to get my head wrapped
around SQL. Basically the Query deletes from the Import table all
records that are already in FooStrings so that when I do an insert from
the FooStringsImport table into the FooStrings table, then I won't get
primary key violations.
DELETE FROM FooStringsImport
WHERE EXISTS
(SELECT * FROM FooStrings
WHERE FooStringsImport.FooKey = FooStrings.FooKey)
It seems to work fine, but I'm wondering about how the EXISTS keyword
works.
(SELECT * FROM FooStrings
WHERE FooStringsImport.FooKey = FooStrings.FooKey)
This part is going to return only records from FooStrings correct? Or
does it do a cartesian product since I've specified more than one table
in the WHERE statement?
I wonder if it only returns records in FooStrings, then I don't see how
a record from FooStringsImport would "EXISTS" in the records returned
from FooStrings.
The reason I wondered about the cartesian product is because, if only
FooStrings is specified in the FROM part of the SELECT statement, then
I was thinking it is only going to return FooString records. These
records would then be returned by the select statement to the WHERE
EXISTS, which would look for FooStringImport records, but would find
none because the select statement only returned FooString records.
I'm guessing maybe because it has to do a cartesian product to evaluate
the WHERE Pkey's equal, then the "SELECT *" just goes ahead and gets
ALL the fields, and not just those in FooStrings.
FooStrings and FooStringsImport are identically structured tables,
where the FooKey is set as the primary key in each table:
Thanks in advance. I'm so appreciative of the help I've gotten here,
as I've been able to write several very useful queries on my own now
after everyones help and plus lots of reading on my own.
I've created a new table in ASPNETDB.mdf called 'customerInfo'. Most of the fields are, for the moment, data that exists in one of the existing ASPNET tables eg Membership_UserId (primary key), Membership_Email, Users_UserName etc.; the list goes on. I have put a new column 'amountspent' - just to test that I can do what I think I can do, however the table doesn't display any data. Am I OK in thinking that I can use the aspnet data in my own tables and reference through foreign keys to them. I've made sure that the procedure that I used to put the table into a gridview on the webpage is OK as I did the same thing to the membership table and that displays all of its data. Can someone either explain the steps I need to make this happen correctly or point me in the direction of a noob type walkthrough. Thanks
How do you concatinate fields in SQL? I tried in a SQL query, but did not have any success. I'm coming from MS Access where it is simple to add fields together.
You could add fields and put characters between the two different fields like a space and/or some sort of seperation character (/,-,_,:) in an expression. Then you could call that expression from whatever you wanted.
Is there a way to do this in SQL Express 2005? Do I do it in a query? Can I add seperation characters?
Thanks
PS. If you have a good link to the basics of SQL queries, I would look at that as well.
I have a table which has the column [itemNumber] Which contains numbers from 000 to 999. I have another table which has the UPC data for given items I am trying to get results from my query that will show me every number in the itemNumberSet table that does not already exist (in the substring) of the UPCcode column.
By using the query below i am able to retrieve the opposite, and it works by returning results that do exist in the UPCcode column. But I cannot seem to get it to do the opposite which is what i am after. I figured it would be as simple as using NOT IN but that returned 0 results.
SELECT itemNumber FROM itemNumberSet WHERE itemNumber IN (select SUBSTRING(UPCcode, 9, 3) FROM itemUPCtable) ORDER BY itemNumber
What I want to do is update 1 table based on data in another. This query works great in Access XP, but I cannot make it work in SQL 2000 sp3. Is there a different way to populate table A with direct data from table B in an update?
Any help is appreciated

hello everybody! I'm using ssce. I'm trying to add the followed query in my table adapter but in the query builder (VS), when I choose execute query, I get a couple of textboxes but whatever I type in, I get an error message "The parameter is wrong"
here is the query: SELECT EntryID, UserInfo, Kind, ActionDate, Span, SalaryAtAction FROM Logbook WHERE ((CASE WHEN @Enter = 0 AND @Exit = 0 THEN 0 WHEN @Enter = 1 AND @Exit = 0 AND kind = '?????' THEN 1 WHEN @Enter = 0 AND @Exit = 1 AND kind = '?????' THEN 1 WHEN @Enter = 1 AND @exit = 1 AND kind IN ('?????', '?????') THEN 1 ELSE 0 END) = 1)
what I try to implement is, a table that one of it's columns is bit datatype. the end-user can filter out the table by these parameters whether to show only the true rows or only the false rows or both.
would you suggest to use a different various of the query?

My SQL Query Analyzer just runs the clock but when the clock stops it fails to open the tool. Both my SQL Server 2000 Developer and Enterprise Edition do this. Can anyone suggest how I can get this working? It worked fine in SQL 7.

Hi all, I have a table with 2 columns (simplified for this question): Date and Action
Date is normal datetime, Action is varchar and can be either Sent or Received. The data can look like this:
1. '2008-04-02 15:09:09.847', Sent 2. '2008-04-02 15:09:10.125', Sent 3. '2008-04-02 15:09:11.125', Received 4. '2008-04-02 15:09:12.459', Received 5. '2008-04-02 15:09:15.459', Received 6. '2008-04-02 15:09:24.121', Sent
7. '2008-04-02 15:09:28.127', Received
I want to find a pair of rows Sent-Received with the Max Date difference, where Received follows immediately after Sent.
It means in our example, valid are only lines 2. and 3. or 6. and 7.
In this example, rows 6. and 7. have bigger difference of Dates, so the result of the query should be
6. '2008-04-02 15:09:24.121', Sent, 7. '2008-04-02 15:09:28.127', Received

Edit: Newer mind. I tested this query more after writing this, and now it seems to work!I hope it continues to work. In following query, else is never executed.CREATE PROCEDURE Put_into_basket( @Product_code varchar(20))ASBEGIN SET NOCOUNT ON;IF NOT EXISTS(SELECT * FROM dbo.t_shopping_basket WHERE Product_code=@Product_code) BEGIN INSERT dbo.t_shopping_basket (Product_code, Name,Price) SELECT Product_code, Name,Price FROM dbo.t_product WHERE Product_code= @Product_code ENDELSE --this part is never executed BEGIN UPDATE dbo.t_shopping_basket SET Quantity=Quantity+1 WHERE Product_code=@Product_code ENDENDGO The query should test if there is a record or row with Product_code=@Product_code. If there is not, that is the first part, one such row is inserted. Quantity has a default value of 1. Insertion works, one row is inserted. At least sort of. If there is already record, That's later part, Quantity is increased by 1. That too works, if ran separately.But when I test query, it never runs the quantity+1 part.
I am currently stuck on how to make this 2 separate query work together, both work as i want them to individually, please note the syntax is according to a application i use that uses mysql to manipulate columns in an imported csv file.
CONCAT('at-', REPLACE([CSV_COL(18)],'http://www.homebuy.co.uk/product.php/','') ) removes last character i.e. / SUBSTRING([CSV_COL(18)], 1, CHAR_LENGTH([CSV_COL(18)]) - 1)
basically i need these 2 to work together to give me an output like this
at-09fd8903
from the this. URL...url above minus the "" as i said both work on there own, but not together.
I have recently upgraded my Access Database too use SQL server 2005 using the upsizing wizard. I have selected too use SQL Linked tables instead off the ADP project for ease off conversion. So now the tables are on the SQL server and the queries are still local.
On off my Access forms which returns a datasheet view by accessing the a query is now running really slowly now SQL server is the backend, I was wondering if I can put an index on one of the tables too speed it up, as the query is local too Access will this work? Just wondering if anyone ever come across this.
I have my db in a pocket pc wm5.0, I just want to make a simple query select * from table where pk = '1' but this doesnt work, if you tried any other field else than the primary key it works... WHY???

I have a script to bulk copy data from my table into textfile. This bcp script will be executed by xp_cmdshell. When I try to execute the scipt inside query windows it returned an error : Error = [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified. But when I test the bcp script in command prompt it will execute successfully
Is there any misconfiguration ? (I'm using sqlexpress) thanks in advance.
I am trying to run the below query in SSIS, However it does not work, but when I try to run the same query in Oracle client it works fine. Here is the following query:
select 'AAA-'||OWNER AS SOURCE, table_name, column_name, SUBSTR(data_type,1,50) DATA_TYPE , SUBSTR(decode(data_type,'NUMBER', DATA_PRECISION, DATA_LENGTH),1,20) DATA_LENGTH from all_tab_cols where owner='XXX' ORDER BY TABLE_NAME, COLUMN_ID
Here ARE the following errorS I get when running from SSIS:
[ORA_AAA_XXX [147]] Error: There was an error with output column "SOURCE" (612) on output "OLE DB Source Output" (157). The column status returned was: "The value could not be converted because of a potential loss of data.".
[ORA_AAA_XXX [147]] Error: The "output column "SOURCE" (612)" failed because error code 0xC0209072 occurred, and the error row disposition on "output column "SOURCE" (612)" specifies failure on error. An error occurred on the specified object of the specified component.
I am trying to create a script that will return information from 4 different tables in a database using different where clauses.
This is working correctly, however the primary table the query uses has multiple entries for different people and i only want to return the last row per person. I have got this to work using a MAX(t.column) statement, but when used in conjunction with all the where clauses things go wrong.
This is what i have
Code:
CREATE VIEW Firereport1 AS
select max(t.punch_id) as punch, e.EMPLOYEE_FIRSTNAME, e.EMPLOYEE_LASTNAME, c.CLOCK_NAME, t.PUNCH_TIME, d.DEPT2_DESCRIPTION
FROM TM_PUNCH t, EMPLOYEE e, COMM_CLOCK c, DEPT2 d
WHERE t.PUNCH_EMPID = e.EMPLOYEE_ID and e.EMPLOYEE_ONCLOCK <> 'False' and e.EMPLOYEE_LASTTIMELOC = c.CLOCK_ID and e.EMPLOYEE_LASTDEPT2 = d.DEPT2_ID
group by e.EMPLOYEE_FIRSTNAME, e.EMPLOYEE_LASTNAME, c.CLOCK_NAME, t.PUNCH_TIME, d.DEPT2_DESCRIPTION
GO
This returns multiple entries because there are multiple unique entries for t.punch_time.
What i was thinking is i need a where statement on t.time_punch, d.dept2_description, c.clock_name that says something along the lines of where return t.punch_time where t.punch_id=punch (**substitute correct column names**)
just wanted to ask the most efficient way to query for the following: say i have a table with the following columns A, B, C, D, E. i want to find the records whose A, B and C are the same but at least D or E are different and then display all the columns (A to E) for these records. thank you!
So as the subject states, I'm a total sql noob. I have a database in SQL 2k5 that was transfered over from an acces DB. In the sql db there are a few fields using nvarchar(255) but the data held is actually dates and times. I need to convert these over to datetime format but do no know how. Also, not all rows have a full mm/dd/yyyy hh:mm format. some hold only the date and can be seen as either m/d/yyyy or full out mm/dd/yyyy format. If anyone can help with this that would be great.
I installed sql sever 2005 enterprise edition in my computer.Where is the management studio? Is it a different program? Can I install the express edition of the management studio?Help please.
Ok so i have something like this for a simple quary,
select avg(reorderlevel)/ (avg(QOH)/(avg(reorderlevel)*2)) as "Needed qty",ItemCategory from item group by ItemCategory
What I basicly need to do is to output the quantity needed for QOH to be 2 times the amount of reorderlevel. then grouped by diffrent catagories.
Anyways I have the formula done and it should work except for some reason "(avg(QOH)/(avg(reorderlevel)*2))" gives me 0 when in fact it should give me 0.728383 or w/e. Im wondering if its omiting the decimals or what??
Because if i run that code it tells me i cant divid by zero
Sorry im new at this and might be doing this all wrong so go easy on me =/
Apologies first up -I dont do security so slapped wrists all round, but I have a little situation that I need to take seriously so I thought I'd try do the job right for a change. Scenario: I have a stored procedure that I want one, and only one, 'thing' to have access to. The 'thing' will be one and only one SSIS package invoked by external scheduling software so basically a call to the dtexec utility to run the package stored in the file system. At runtime therefore, this package has an ExecuteSQL task which connects to the server and runs the sproc. Given windows authentication how do I ensure that the ONLY user allowed to execute the stored procedure is whatever user happens to invoke the package but that this same user can never log in to sql server and execute the stored procedure. In even simpler terms, I want nothing on earth to run that stored procedure nor select the data from the table other than this package when it runs, regardless of who runs it, it is only internal processing by the package that gets the data.
