Hello:
I want find that the ntext column data string have more than 2000 characters. I need to truncate those string to segment with 200 character, then put those segments along with their table_name and column_name to another table. Maybe need to use cursor? If so, how to use it?
Your help is highly appreciated.

How can I create a Cursor into a Stored Procedure, with another Stored Procedure as data source?
Something like this:
CREATE PROCEDURE TestHardDisk
AS
BEGIN
DECLARE CURSOR HardDisk_Cursor
FOR Exec xp_FixedDrives
-- The cursor needs a SELECT Statement and no accepts an Stored Procedure as Data Source
OPEN CURSOR HardDisk_Cursor
FETCH NEXT FROM HardDisk_Cursor
INTO @Drive, @Space
WHILE @@FETCH_STATUS = 0
BEGIN
...
END
END
I have a stored procedure that basically recieves the where clause of a select statement and executes the new sql statement... ie:
CREATE PROCEDURE [dbo].[bsa_GetImportIDs]
(@FilterText varchar(1000))
AS
DECLARE @MySQL varchar(1000)
SET @MySQL = "SELECT Import_ID FROM tblImport WHERE " + @FilterText
EXEC (@MySQL)
GO
Now, in another stored procedure, I need to use the stored procedure above in a cursor so that I can execute an insert statement for each occurance of the Import_ID that appears in that dataset... ie:
CREATE PROCEDURE [dbo].[bsa_PutLargeCase]
AS
DECLARE @CaseID uniqueidentifier
SET @CaseID = NewID()
Declare @ImportID uniqueidentifier
Declare curClient Cursor FAST_FORWARD for
SELECT Import_ID FROM dbo.bsa_GetImportIDs (@FilterText) <---- this does not work!!!
Open curClient
FETCH NEXT FROM curClient INTO @ImportID
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC dbo.bsa_PutCaseDetail @CaseID, @ImportID
FETCH NEXT FROM curClient INTO @ImportID
END
CLOSE curClient
DEALLOCATE curClient
GO
How can I utilize my first stored procedure in the cursor of the second? ... or
Are there any other approaches that may be a better solution to what I am trying to accomplish?
Thanks in advance for any input.

Hi,everyone.
Why need to open CURSOR in the part in which a procedure is created?
The following codes are listed in the Microsoft SQL Server 2005 BOOKS ONLINE.
(1)
USE AdventureWorks;
GO
IF OBJECT_ID ( 'dbo.currency_cursor', 'P' ) IS NOT NULL
DROP PROCEDURE dbo.currency_cursor;
GO
CREATE PROCEDURE dbo.currency_cursor
@currency_cursor CURSOR VARYING OUTPUT
AS
SET @currency_cursor = CURSOR
FORWARD_ONLY STATIC FOR
SELECT CurrencyCode, Name
FROM Sales.Currency;
OPEN @currency_cursor;
GO
(2)
USE AdventureWorks;
GO
DECLARE @MyCursor CURSOR;
EXEC dbo.currency_cursor @currency_cursor = @MyCursor OUTPUT;
WHILE (@@FETCH_STATUS = 0)
BEGIN;
FETCH NEXT FROM @MyCursor;
END;
CLOSE @MyCursor;
DEALLOCATE @MyCursor;
GO
Please help me. Thank you in advance!
can someone tell me how to use static cursor to read the rows applying it in procedure.
i have input and output tables
i will have to use input table to read data and then in procedure update/insert into output table ) insert values from input and dditioanl calulate charges.
ok, there is my problem:
An Internet service provider has three different subscription
packages for its customers:
Package A: For $15 per month with 50 hours of access provided.
Additional hours are $2.00 per hour over 50 hours.
Assume usage is recorded in one-hour increments,
i.e., a 25-minute session is recorded as one hour.
Package B: For $20 per month with 100 hours of access provided.
Additional hours are $1.50 per hour over 100 hours.
Package C: For $25 per month with 150 hours access is provided.
Additional hours are $1.00 per hour over 150 hours
Assume a 30-day billing cycle.
1) Create a table to hold customer input billing data.
2) Populate input table with follwing records:
CustomerID Pkg Hours
---------- --- ------
1000 A 49
1010 A 50
1020 a 90
1030 a 130
1090 B 40
1100 B 99
1110 b 100
1120 b 145
1140 C 45
1150 c 85
1160 c 149
1170 c 150
1180 c 200
3) Create a table to hold customer data used to generate
the statement to be sent to the customer. It should
include CustomerID, Package, HoursUsed, and Charges.
Write an SQL script that reads customer billing data,
calculates a customer’s monthly charges, and populates
the customer statement table.
Use Cursor to process records and Stored Procedures for
ProcessBill and calcCharges.
CREATE TABLE custinput(
cust_id int NULL,
pkg char(1) NULL,
hrs smallint NULL
)
CREATE TABLE custoutput(
cust_id int NULL,
pkg char(1) NULL,
hrsused smallint NULL,
charges money null
)
insert into custinput values (1000,'A',49);
insert into custinput values (1010,'A',50);
insert into custinput values (1020,'a',90);
insert into custinput values (1030,'a',130);
insert into custinput values (1090,'B',40);
insert into custinput values (1100,'B',99);
insert into custinput values (1110,'b',100);
insert into custinput values (1120,'b',145);
insert into custinput values (1140,'C',45);
insert into custinput values (1150,'c',85);
insert into custinput values (1160,'c',149);
insert into custinput values (1170,'c',150);
insert into custinput values (1180,'c',200);
then there is conditions:
if upper (@pkg)= 'A'
begin
if @hrs<= 50 set @charges =15
else set @charges =15 + (@hrs-50)*2
end;
else if upper(@pkg)= 'B'
begin
if @hrs <= 100 set @charges = 20
else set @charges = 20 + (@hrs - 100)*1.5
end;
else
if @hrs <=150 set @charges = 25
else set @charges =25+(@hrs-150)
insert into custoutput values(@cust_id,@pkg,@hrs,@charges)

Basically, I have a complex stored procedure that combines two tables and fills a cursor.
I would like to fill another cursor in another stored procedure from the results of this first stored proc, rather than have to type it all in again.
The reason being that I am doing a one time import of some data from two tables into one new table based on some complex linking/querying.
Can I fill a cursor from the output of another stored procedure rather than an inline SELECT statement?
Does the sp I am using have to have cursor as an out parameter?
What is error here when i declare cursor ?

I need to write a stored procedure using T-SQL to declare a cursor for containing id(staff_no), names and specialism of all doctors that have specialism, The contents of the cursor then are to be displayed using a loop and print statement to give a formatted display of the output of each record within the cursor.
The doctors table has the following columns with specialism allowing NULL values
doctor
(
staff_no CHAR(3),
doctor_name CHAR(12),

I have created the following stored procedure to get the text from one table and compare with them with another table and the one's that match will assign the corresponding ID.

The tile says it all... How to put into a Cursor the result of a procedure that selects certain rows.
View 1 Replies View RelatedCan someone post some code that shows a Stored Procedure receiving a cursor that it can process - lets say a group of order detail records are received that must be saved along with the single Order header record.
And, in another example, a SP returns a result set to the calling program. - For example, a particular sale receipt is pulled up on the screen and the order detail is needed.

Hi,
I have a kind of problem. In SQL Server I have a stored procedure ressembling this:
Code Block
ALTER PROCEDURE procedure1
(
@param int
)
SELECT * FROM table WHERE param = @param
Now I want to call this procedure and pass it to a cursor. We all know you can do this:
Code Block
DELCARE cursor1 CURSOR for
SELECT * FROM table WHERE param = @param
.. , but I want something like this:
Code Block
DECLARE cursor1 CURSOR for
EXEC procedure1 @param
Is it possible? I could solve it in another, but then I have to connect 2x to the database, which is less performant.
I have also tried something like this:
Code Block
ALTER PROCEDURE procedure1
(
@param int
)
SELECT @test = id FROM table WHERE param = @param
RETURN @test
ALTER PROCEDURE procedure2
(
@param int
)
DECLARE @var varchar(100)
EXEC @var = procedure1 @param
But then it returns always 0.
So is there a way to pass a procedure's select to a cursor?
Thanks in advance

I'm working on a procedure that needs to cycle through the records of some raw data and combine the the current record with the datetime field of the prior record. I have been able to write a script to do that with cursors and variables but my problem is it returns each record separately. How do I go about getting the procedure to return all the records as one set of data?
To see what I mean, the following script for the Pubs DB returns each pass through the data as a seperate query. Since I can't do a select *, what approach should I take? If you want the actual script, I would be happy to provide it.

I appear to be having an issue where the @LetterVal and @Numeric variables aren't resetting for each loop iteration, so if no results are found, it just returns the previous loops values since they aren't overwritten. Below is the stored procedure I've created:
ALTER PROCEDURE [dbo].[ap_CalcGrade]
-- Add the parameters for the stored procedure here
@studId int,
@secId int,
@grdTyCd char(2),
@grdCdOcc int,
@Numeric int output,
[Code] ....
And below is the "test query" I'm using:
-- *** Test Program ***
Declare @LetterVal varchar(2), -- Letter Grade
@Numeric int, -- Numeric Grade
@Result int -- Procedure Status (0 = OK)
Execute @Result = dbo.ap_CalcGrade 102, 86, 'QZ', 3,
[Code] ....
This is resulting in an output of:
A+ 97
A+ 97
C- 72
but it should be returning the output below due to the 2nd data set not being valid/found in the sp query:
A+ 97
No Find
C- 72
I'm sure this is sloppy and not the most efficient way of doing this, so whats causing the errant results, and if there is any better way I should be writing it. Below is the assignment requirements:
Create a stored procedure using the STUDENT database called ap_CalcGrade that does the following:
1. Accepts as input STUDENT_ID, SECTION_ID, GRADE_TYPE_CODE, and GRADE_CODE_OCCURRENCE
2. Outputs the numeric grade and the letter grade back to the user
3. If the numeric grade is found, return 0, otherwise return 1
4. You must use a cursor to loop through the GRADE_CONVERSION table to find the letter grade
I currently have a process that has a cursor. It takes data and executes a stored procedure with parameters.

The following Client3 accounts have A1 value and a blank A2 field. Accounts: Ac1,Ac2,Ac3,

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.

View 3 Replies View Related In MSDN file I read about static cursor
STATIC
Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in
tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that

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

I am begginner at best so I hope someone that is better can help.I have a stored procedure that updates a view that I wrote using 2cursors.(Kind of a Inner Loop) I wrote it this way Because I couldn'tdo it using reqular transact SQL.The problem is that this procedure is taking longer and longer to run.Up to 5 hours now! It is anaylizing about 30,000 records. I thinkpartly because we add new records every month.The procedure works like this.The first Cursor stores a unique account and duedate combination fromthe view.It then finds all the accts in the view that have that account duedatecombo and loads them into Cursor 2 this groups them together for datamanipulation. The accounts have to be grouped this way because aaccount can have different due dates and multiple records within eachaccount due date combo and they need to be looked at this way aslittle singular groups.Here is my procedure I hope someone can shead some light on this. Myboss is giving me heck about it. (I think he thinks Girls cant code!)I got this far I hope someone can help me optimize it further.CREATE PROCEDURE dbo.sp_PromiseStatusASBEGINSET NOCOUNT ON/* Global variables */DECLARE @tot_pay
