Using Select Statement Instead Of Cursor
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.

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

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

Moving Average Using Select Statement Or Cursor Based?
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
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?

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

Help With Cursor And Fetch Statement
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), @ItemKey Int, @WhseKey Int, @ShortDesc VarChar (40), @StdCost Decimal (16,8) DECLARE Temp_cursor CURSOR FOR SELECT TranID, TranDate, QtyRcvd, UnitCost, ItemKey, WHseKey, ItemID, ShortDesc, WhseID, QtyOnHand, StdCost FROM #Temp1 tem OPEN Temp_cursor FETCH NEXT FROM Temp_cursor INTO @TranID, @TranDate, @QtyRcvd, @UnitCost, @ItemKey, @WHseKey, @ItemID, @ShortDesc, @WhseID, @QtyOnHand, @StdCost WHILE @@FETCH_STATUS = 0 BEGIN -- 0 Insert Into #Temp3 (TranID, TranDate, QtyRcvd, UnitCost, ItemKey, WHseKey, ItemID, ShortDesc, WhseID, QtyOnHand, StdCost) Values (@TranID, @TranDate, @QtyRcvd, @UnitCost, @ItemKey, @WHseKey, @ItemID, @ShortDesc, @WhseID, @QtyOnHand, @StdCost) FETCH NEXT FROM Temp_cursor INTO @TranID, @TranDate, @QtyRcvd, @UnitCost, @ItemKey, @WHseKey, @ItemID, @ShortDesc, @WhseID, @QtyOnHand, @StdCost

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

Cursor Vs. Select
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

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

Variable As Column In Cursor Select
I can't seem to get a cursor to work when I'm passing in a variable for a column name of the select statement. For example: declare @col varchar(50) set @col = 'Temperature' declare notifycurs cursor scroll for select @col from Table Obviously this won't work correctly (since the result will simply be 'Temperature' instead of the actual float value for temperature). I tried to use quotes for the entire statement with an EXEC (ie. exec('select '+@col+' from Table' ) but that gave me an error. Is there a way to pass in a variable for a column name for a curor select statement????

Adding Variable To SELECT For CURSOR
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.

Stored Procedure With CURSOR OUTPUT Parameter, Using JDBC And A Callable Statement
My server is MS Sql Server 2005. I'm using com.microsoft.sqlserver.jdbc.SQLServerDriver as the driver class. I've established a connection to the database. I'm trying to invoke a stored procedure using JDBC and a callable statement. The stored procedure has a parameter @CurOut CURSOR VARYING OUTPUT. How do I setup the callable statement so the output parameter is accepted by the driver? I'm not really trying to pass a cursor up to the database Server but I'm wanting a cursor back from the stored procedure that is other than the result set or other value the stored procedure returns. First problem: What java.sql.Types (or SQL Server specific) value do I specify for the out parameter I'm registering on the CallableStatement? Second problem: What do I set the value of the parameter to? The code looks like: CallableStatement cstmt = myConnection.prepareCall(sQuery); cstmt.registerOutParameter(1, Types.OTHER); // What is the right type? cstmt.setNull(1, Types.OTHER); // What is the right type? if (cstmt.execute()) { ResultSet rs = cstmt.getResultSet(); } Execution results in a NullPointerException from the driver. What am I doing wrong? Thanks for your assistance. Jon Weaver

Incrementally Build Cursor Select Using CASE?
In Access/VB/DAO I can declare a string variable to contain my SELECT statement. If I do this I can build the string incrementally and finally open the cursor using OpenRecordset(strSQL). I'd like to be able to do this in SQL7. Let me illustrate: In Access97: Function Test(ByVal pstrOrder As String) As Boolean Dim strSQL As String strSQL = "SELECT * FROM tblEmployee " Select Case pstrOrder Case "Alpha" strSQL = strSQL & "ORDER BY [LastName], [FirstName]" Case "SSN" strSQL = strSQL & "ORDER BY [SSN]" End Select db.OpenRecordset(strSQL) End Function This is a very simple example....I have a lot of complex SELECT statements and I don't want to retype the same code in the same procedure that does ALMOST the same thing. I'm hoping to use something like the CASE construct: DECLARE csrEmployee CURSOR FOR SELECT * FROM tblEmployee (CASE @pstrOrder WHEN "Alpha" THEN ORDER BY LastName, FirstName WHEN "SSN" THEN ORDER BY SSN END) Can anyone out there help?

Output Of Select Stament Into Variable Within Cursor
Within a cursor that I am building I would like to execute a select statement built from a varchar variable as such: SELECT @BuildDBPageUsed = 'SELECT sum(reserved) FROM ' + @DatabaseName + '.dbo.sysindexes WHERE segment <> 2' Next I execute the statement, which is now in the variable @BuildDBPageUsed. Such as: EXEC (@BuildDBPageUsed) The resulting output I need to set to another variable @DBPageUsed which is integer. I have been unsuccessful in finding the correct set of commands to do this. How should I build the command to input the results of the EXEC (@BuildDBPageUsed) into the integer variable @DBPageUsed? *Thanks* for any help in this matter. Brad

Hi All, Can some one point me in the right direction in how to construct my SQL query within my cursor? I Have got a cursor which i am using to iterate through a table, What i am trying to do is in my statement(used to open the cursor) is compare 2 tables (the one which my cursor is iterating) to see if there is a matching row in the other table (using both tables ID's Like So: SELECT column_List FROM Table1 WHERE Table1_id = Table2_id so for each row my cursor checks if there is a corresponding match in table2... but i would like to write to an error log and do other statements if there is no match how do i add this condition to my statement either using an if...else statement proceeding to the next row? here is the statment i attempted to write: SELECT column_List FROM table1 WHERE Table1_id = Table2.id now i want to incoporate the statements below into the statement above as a condition when table1.id <> table2.id IF table1.id <> table2.id BEGIN SET @DebugMessage = 'data not live.' RAISERROR (@DebugMessage, 16, 1) WITH LOG END essentially what i am trying to sayin my statement is: go to the first row check if it has a match in table 2, if there is no match execute a number of statements such as error loging e.t.c go to the next row repeat the previous statements ...i also looked through some Case...When statements am just not sure how to put in the condition thanks in advance

Dynamic Cursor Versus Forward Only Cursor Gives Poor Performance
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin
