How To Specify Which Database To Use For A Select Statement Within A Cursor?

Nov 9, 2007

Hi everyone,

I have been trying to perform the following task:

Using the sys.databases & sys.sysindexes views to display all the columns with a clustered index for all tables and all databases in a given server. So the end result will have 3 columns:

Database name
Table name
Column name from that table with a clustered index

I have already created the following script which displays all the databases for a given server:

declare @DBname nvarchar(128)
declare testCursorForDB cursor
for
select name from sys.databases with (nolock)
where name not in ('master','tempdb','model','msdb')
order by name

open testCursorForDB
fetch next from testCursorForDB
into @DBname

while @@fetch_status = 0
begin
print @DBname
fetch next from testCursorForDB
into @DBname
end

close testCursorForDB
deallocate testCursorForDB

I also have created the following query which will display all the table and column names which have a clustered index for a given database:

select object_name(i.id) as TableName,

i.name as IndexName
from sys.sysindexes as i with (nolock)
where i.indid = '1'

However, what I need help/advice on is how do I combine these two together into one working script (either using nested cursors or a better way). In other words, how can I specify which database to use (ie. using the "use database_name") so that my query above will be applied to each database found within the cursor.

Any help is greatly appreciated

Thanks!

Select Statement In Cursor

Mar 26, 2000

Hi...


I have a stored procedure that rertrieves data from an sql database
and sends out a mail to each receipient who meets the criteria

I am using SQL mail.


I dynamically generate the where clause for my sql query based on criteria taken
from other stored procedures and store it in a varchar variable
called @sqlquery

When i have the following code to run my cursor

DECLARE overdue3 CURSOR
LOCAL FORWARD_ONLY
FOR SELECT DISTINCT Events.E_Name, Events.E_SDate, Events.E_City,
Events.E_ID FROM Events, IndustryEvents + @sqlquery2
OPEN overdue3

I get an error message at the '+' sign
which says, cannot use empty object or column names, use a single
space if necessary.

What should i do. i have tested the variable @sqlquery and it is
definately not blank. There is no bracket error or anything.

Please help!!!

Thanks much indeed

Ramesh

Using Select Statement Instead Of Cursor

May 20, 2003

Hi All, Can anyone please help?

TableA has data as below:

ssn sex dob rel_code
111111111 m 19500403 m
111111111 f 19570908 w
111111111 f 19770804 d
111111111 f 19801203 d
111111111 f 19869712 d
111111111 m 19870907 s
111111111 m 19901211 s

I have to convert the rel_code into a specific manner so the data will look as below in TableB:

ssn sex dob rel_code
111111111 m 19500403 01
111111111 f 19570908 02
111111111 f 19770804 20
111111111 f 19801203 21 111111111 f 19869712 22
111111111 m 19870907 30
111111111 m 19901211 31

Member's rel_code = 01
spouse's rel_code = 02
daughter's rel_code starts from 20 with the oldest and increments by 1.
Son's rel_code starts from 30 and increments by 1 from oldest to the youngest.

I know You can write a Sp with cursor and do this, but I would like to know if you can accomplish the same thing by a select or case or something else instead of a cursor.

Thanks in advance.

Moving Average Using Select Statement Or Cursor Based?

Jul 30, 2007

ID DATE(dd/mm/yy) TYPE QTYIN COST_IN_AMT COST_OUT_AMT(MOVING AVERAGE)
1 01/01/2007 PURCHASE 10 1000
2 01/01/2007 PURCHAES 5 1100
3 01/01/2007 SALES -5 *TobeCalculated
4 02/01/2007 Purchase 20 9000
5 02/01/2007 SALES -10 *TobeCalculated
5 02/01/2007 purchase 50 8000
6 03/01/2007 Sales -10 *TobeCalculate
7 01/01/2007 Purchase 20 12000

I have a table when user add new sales or puchase will be added to this table ITEM_TXNS. The above date is part of the table for a ProductID . (The field is removed here)
In order to calculate the balance amount using moving average, I must calculated the cost_out_amt first on the fly.
When user add new sales I also need to determine the cost/unit for a product id using moving average. The problem is I can not just use sum, because i need to determine cost_out_amt for each sales first which will be calculated on the fly.
The reason i dont store the cost_out_amt (instead calculate on the fly) because User could Edit the previous sales/purchase txn or Insert new sales for a previous date. Example THe record with ID 9. By Adding this txn with ID 9, would cause all the cost_out_amt will be incorrect (Using moving Average) if i store the cost_amout_out on entrying txn and need to be recalculated.
Instead I just want to calculate on the fly and able to determine the cost avr for a specific point of time.
Should I just use Cursor and loop all the record and calculate the cost or maybe I can just use on Select Statement?

Combing In A Cursor, A Select Statement With The WHERE Clause Stored In A Variable

Mar 28, 2000

Hi
I am ramesh here from go-events.com
I am using sql mail to send out emails to my mailing list


I have difficulty combining a select statement with a where clause stored in a variable inside a cursor

The users select the mail content and frequency of delivery and i deliver the mail

I use lots of queries and a stored procedure to retrieve thier preferences. In the end i use a cursor to send out mails to each of them.

Because my query is dynamic, the where clause of my select statement is stored in a variable. I have the following code
that does not work

For example

DECLARE overdue3 CURSOR
LOCAL FORWARD_ONLY
FOR SELECT DISTINCT Events.E_Name, Events.E_SDate, Events.E_City, Events.E_ID FROM Events, IndustryEvents + @sqlquery2
OPEN overdue3

I get an error message at the '+' sign
which says, cannot use empty object or column names, use a single
space if necessary

How do I combine the select statement with the where clause?

Help me...I need help urgently

Order By Clause In DECLARE CURSOR Select Statement Won't Compile

May 7, 2008

The stored procedure, below, results in this error when I try to compile...


Msg 156, Level 15, State 1, Procedure InsertImportedReportData, Line 69
Incorrect syntax near the keyword 'ORDER'.

However the select statement itself runs perfectly well as a query, no errors.

The T-SQL manual says you can't use the keywords COMPUTE, COMPUTE BY, FOR BROWSE, and INTO in a cursor select statement, but nothing about plain old ORDER BYs.

What gives with this?

Thanks in advance

The Select Statement Was Denied On The Object 'table Name' , Database 'db Name', Schema 'dbo'

Nov 12, 2007



Hi,

I have a select statement running on the client machine linking to different tables in 1 database. All with the same schema. When I ran it, i had this error. I had trial and error, removing 1 table at a time until i hit the one which is causing it. when i removed it, everything's ok. i just wonder if all the tables were using dbo schema what is causing this particular table to throw this error?

Need Help With A SQL Statement - Trying Not To Use A Cursor

May 25, 2007

I'm just know basic SQL but not enough to write any complex queries.The problem I'm facing right now keeps me thinking to use a Cursor butI've seen a lot of posts on here saying Cursors are bad so I'm hopingthere is a complex query that can give me the data I need.I have about 6 pages in website where I need to display a datagrid ofinformation. There should be 5 columns, Filename, and then 4 CategoryTitles (These category titles are stored in a table calledPageCategory). I have another table, XREF_Doc_Page that stores thePageID, DocID (ID to know what file it is), and PageCategoryID. So Ican query this table with a pageID to see all the results that shouldbe on this page but I don't know how to format it the way I need mydatagrid?In order to have the records from PageCategory be columns, is this acrosstab query or something?My only thoughts right now are to user a cursor to query Pagecategoryand build a temp table somehow with these as the columns?? (Not surehow'd that would work yet).So the datagrid would have the 5 columns like I said and then justlist all files associated with this page and put a checkmark underwhichever category it was assigned to (example below...)Files PageCat1 PageCat2PageCat3 PageCat4abc.pdf Xxyz.pdf Xjkl.pdfx

Using Cursor For Update Statement?

May 9, 2012

I would like to get the results of a cursor into update statement but it fills only the last record of the cursor

this is the cursor:

Code:
DECLARE @avg varchar(50)
DECLARE @cur_avg CURSOR
SET @cur_avg = CURSOR FOR
select cast(avg(cast(reply as decimal(12,2))) as decimal(12,2)) from tbl_app_monitoring
group by test_name, application_id

this is the update statement:

Code:
OPEN @cur_avg
FETCH @cur_avg INTO @avg
WHILE (@@FETCH_STATUS = 0) BEGIN
UPDATE tbl_app_monitoring_archive
SET average = @avg
FETCH @cur_avg INTO @avg
END

is it also possible to do this without the cursor ?

Cursor And USE Statement With Variables

Sep 18, 2013

I have a cursor that goes through a table with the names of all the database in my server. So for each fetch, the cursor gets the name of a database and assign it to a variable, @databaseName, and try to do some queries from that database by using the command "USE @databaseName". But "USE" doesn't take the variable @databaseName; it is expecting a database name (i.e. USE master).

Here is my code:

Declare @databaseName varchar(50)
Declare c_getDatabaseName CURSOR for SELECT name from tblDatabases
OPEN c_getDatabaseName
FETCH NEXT from c_getDatabaseName into @databaseName
While @@FETCH_STATUS = 0

[Code] ....

How to get USE to take the variable value ?

Help With Cursor And Fetch Statement

Mar 17, 2008

Hello,

I am hoping someone can help me with using the cursor and fetch functions. I have not used these features in the past and I am now stuck when trying to use IF statements with the fetch function.

I have a temp table populated with the below headers and their associated data.

The headers are as follows:
ItemRcvdKey, TranID, TranDate, QtyReceived, UnitCost, ItemKey, WhseKey, ItemID, ShortDesc, WhseID, QtyOnHand, StdCost.

The information contained in this temp table lists every single receipt of goods against all of our inventoried items. The QtyOnHand listed on each record is the total QtyOnHand for that item in that warehouse. What I need the fetch to do is grab the receipt of goods records, starting with the most recent TranDate, and pull them into the new temp table until the QtyOnHand is reached. The QtyonHand it should be comparing too is the one listed on the first fetched record. Once the Sum of the QtyRcvd is equal to or is greater than the QtyOnHand for that item I need the fetch to move on to the next item number and perform the same function.

One thing I need to be clear on is that if there are 3 Receipt Records(TranID) for Item A in Warehouse A, the total QtyOnHand will be listed 3 times. I need to make sure that the Fetch is comparing all the records for Item A in Warehouse A to one instance of the QtyOnHand.

The other aspect is that there will be receipt of goods for the same item in multiple warehouses. So I also need the Fetch to be sure that when it is grabbing records and putting them in the temp table, it makes sure it is matching the ItemID and the WhseID with the record it started with.

The current script I have written is below. If you can offer any help I would greatly appreciate it.





Code SnippetDeclare @ItemID VarChar(30),
@QtyOnHand Decimal (16,8),
@WhseID VarChar (6),
@SumRcvd Int,
@TranID VarChar(30),
@TranDate DateTime,
@QtyRcvd Decimal (16,8),
@UnitCost Decimal (16,8),

Cursor Vs. Select

Jul 23, 2005

buddies,situation: a processing must take place on every row of a table, andoutput results to another table, that can't be done via an insertinto..select query (let's assume that it's not possible for now).There're 2 solutions I have in mind:1) open a cursor and cycle through each row (The table can have up to1M rows)2) create a clustered index (i.e on an identity column) then have aloop like:declare @i int, @rows int,@col1 varchar(20), @col2 varchar(20),... @coln varchar(20),@outval1 varchar(20),... -- output valuesselect @i=1, @rows = max(xid) from tblname -- xid is clustered indexedwhile (@i<=@rows)beginselect @col1 = col1, @col2 = col2,...@coln = colnfrom tblnamewhere xid = i-- do the processing on the variables-- then insert results to another tableset @i = @i+1endI'd like to know your ideas of which one would be more efficient. Anyother solutions are much appreciatedthanks,Tamy

24000 Invalid Cursor State. Prepared Statement

May 1, 2006

I have written a routine to search a unique record using prepared statement. Its my first sql coding with c++.

I am not using / importing any dlls.

I connect+allocs handels , then use SQLPrepare(StmtHandle, SQLStmt,SQL_NTS); to generate a guery.

I have written bind parameters and sqlexecute +sqlFetch in a loop and loop gets executed till ESC key is pressed.

First time when I bind paramaters using SQLBindParameter it works perfect.

When loop gets executed secondtime onwards, it gives an error.
SQLState: 24000 [ODBC Client Interface]Invalid cursor state.

If I open connection, handles, and prepared starement in same loop, THEN it gives correct record without 24000 error.

I want the advantage of prepared staement. So I do not want to close and open connection and prepare statement every time.

Have I missed any step?
Where & when I should code the cursor type? Any specific libraries I need to link?

Thanks

Another question for all you SQL experts, I have a lot of them. I am trying to select from a table wher some conditions need to be met based on an employee ID. What I am doing is when the rank is a 1,2, or 3 I pick up the text description of that rank. Can I make it so that I get the ID only once and all the text descriptions are on the same line. Here is the sql script along with my current output and my desired output.



--SQL SCRIPT__

select C.empID, B.Rank,B.Text1 as Skills from tbl_survey_rank B , tbl_survey_valueID C
where PATINDEX ( '%'+ltrim(rtrim(B.valueID))+'%', C.text1) >0 and C.empID = '2924'and
(B.Rank ='1'or B.Rank ='2' or B.Rank ='3')

Dynamic Select For CURSOR

May 14, 2008

Hi all

I am trying to do dynamic Select for Cursor. The dynamic would be like this:
IF CONDITION1 IS TRUE:
SELECT CustomerTenderID, CustomerSiteID, ContractPeriod, SupplierID
FROM dbo.tnd_TenderSiteRateConsumptionView
WHERE CustomerTenderID = @CustomerTenderID
IF CONDITION2 IS TRUE:
SELECT CustomerTenderID, CustomerSiteID, ContractPeriod, SupplierID
FROM dbo.tnd_TenderSiteRateConsumptionView
WHERE CustomerTenderID = @CustomerTenderID AND
CustomerSiteID = @CustomerSiteID

etc etc

Here's the cursor


DECLARE RateList CURSOR FOR
SELECT CustomerTenderID, CustomerSiteID, ContractPeriod, SupplierID
FROM dbo.tnd_TenderSiteRateConsumptionView
WHERE (BASED ON CONDITION)
ORDER BY CustomerTenderID,
CustomerSiteID,
SupplierID,
ContractPeriod

OPEN RateList
FETCH NEXT FROM RateList
INTO@CustomerTenderID, @ReturnedCustomerSiteID, @ReturnedContractPeriod, @ReturnedSupplierID
WHILE @@FETCH_STATUS = 0
BEGIN
SET @rowNum = @rowNum + 1

-- DO SOME FUNKY STUFF


FETCH NEXT
FROM RateList
INTO@CustomerTenderID, @ReturnedCustomerSiteID, @ReturnedContractPeriod, @ReturnedSupplierID

CURSOR Select Clause

Oct 11, 2006

I need to dynamically construct the field order of a cursor based on fixed labels from another table, but when I put that resulting query I receive the error:

Server: Msg 16924, Level 16, State 1, Line 78
Cursorfetch: The number of variables declared in the INTO list must match that of selected columns.

I have 6 fields defined in the cursor select, and 6 parameters in the fetch. The results of running the @sql portion returns valid data. Should this be possible to define a parameter containing the select clause of the cursor?

select colnum, coldesc, colname into #ae_defs from ae_adefs
select @Sql = (select colname from #ae_defs where coldesc = 'PATIENT NAME') +
', ' +
(select colname from #ae_defs where coldesc = 'PATIENT NUMBER') +
', ' +
(select colname from #ae_defs where coldesc = 'ACCOUNT NUMBER') +
', ' +
(select colname from #ae_defs where coldesc = 'VISIT DATE') +
', ' +
(select colname from #ae_defs where coldesc = 'VISIT TYPE') +
', DocID from ae_dtl1'

DECLARE myCursor CURSOR FOR
Select @SQL

OPEN myCursor
print @@Cursor_rows
FETCH NEXT FROM myCursor into @var1, @var2, @var3, @var4, @var5, @DocID

Cursor Select And Variables

Oct 23, 2006

I have problems to place my variable into the select statement.

DECLARE @DB_NAME varchar(64)
DECLARE MR_ReqPro_DB_cursor CURSOR FOR
select name from dbo.sysdatabases where name like '%MR_req%'
OPEN MR_ReqPro_DB_cursor
FETCH NEXT FROM MR_ReqPro_DB_cursor
INTO @DB_NAME

WHILE @@FETCH_STATUS = 0
BEGIN
print @DB_NAME; --works fine

Select NAME, FILEDIRECTORY FROM @DB_NAME.MR_ReqPro.RQDOCUMENTS WHERE (FILEDIRECTORY LIKE '%\%');

FETCH NEXT FROM MR_ReqPro_DB_cursor INTO @DB_NAME
END
CLOSE MR_ReqPro_DB_cursor
DEALLOCATE MR_ReqPro_DB_cursor

GO

How could i use a variable like @DB_Name in my select ?

Multiple Tables Used In Select Statement Makes My Update Statement Not Work?

Aug 29, 2006

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly.  My problem is that the table I am pulling data from is mainly foreign keys.  So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys.  I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit.  I run the "test query" and everything I need shows up as I want it.  I then go back to the gridview and change the fields which are foreign keys to templates.  When I edit the templates I bind the field that contains the string value of the given foreign key to the template.  This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value.  So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors.  I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode.  I make my changes and then select "update."  When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing.  The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work.  When I remove all of my JOIN's and go back to foreign keys and one table the update works again.  Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People].  My WHERE is based on a control that I use to select a person from a drop down list.  If I run the test query for the update while setting up my data source the query will update the record in the database.  It is when I try to make the update from the gridview that the data is not changed.  If anything is not clear please let me know and I will clarify as much as I can.  This is my first project using ASP and working with databases so I am completely learning as I go.  I took some database courses in college but I have never interacted with them with a web based front end.  Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

SQL Server 2012 :: Create Dynamic Update Statement Based On Return Values In Select Statement

Jan 9, 2015

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".

Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

TSQL - Use ORDER BY Statement Without Insertin The Field Name Into The SELECT Statement

Oct 29, 2007

Hi guys,
I have the query below (running okay):



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01

The results are just as I need:


Field01 Field02

------------- ----------------------

192473 8461760

192474 22810



Because other reasons. I need to modify that query to:



Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:

Field02

----------------------

22810
8461760

And what I need is (without showing any other field):

Field02

----------------------

8461760
22810


Is there any good suggestion?
Thanks in advance for any help,
Aldo.

Adding Variable To SELECT For CURSOR

Oct 13, 2003

I'm trying to build a select statement for a CURSOR where part of the SQL statement is built using a variable.
The following fails to parse:

Declare Cursor1 Cursor
For
'select table_name from ' + @database + '.Information_Schema.Tables Where Table_Type = ''Base Table'' order by Table_Name'
Open cursor1

That doesn't work, I've also tried using an Execute() statement, no luck there either. Any ideas or suggestions are greatly appreciated.
