ALTER procedure [dbo].[MainSchedule]
as
begin
DECLARE #sup table (supervisorId int)
INSERT INTO #sup SELECT DISTINCT SupervisorId FROM CallPlan .dbo .CallPlanSchedule WHERE MONTH (scheduledate)= MONTH (GETDATE ()) and YEAR (ScheduleDate )= YEAR(GETDATE())
DECLARE CUR CURSOR FORWARD_ONLY FOR SELECT * FROM #sup
DECLARE #suptem int
OPEN CUR
FETCH NEXT FROM CUR INTO #suptem
WHILE ##FETCH_STATUS =0

Could not find stored procedure 'dbo.randomOutlet'."
please help me solve this problem thank in advance
I tried the following and got everything running fine.
CREATE procedure CALL_PROC --'abc'
#var varchar(100)
as
begin
declare #sup table (item int)
insert into #sup select 1 union select 2
DECLARE CUR CURSOR FORWARD_ONLY FOR SELECT * FROM #sup
DECLARE #var1 int
OPEN CUR
FETCH NEXT FROM CUR INTO #var1
WHILE ##FETCH_STATUS =0
BEGIN
EXEC dbo.call_me #var1
FETCH NEXT FROM CUR INTO #var1
END
CLOSE CUR
DEALLOCATE CUR
end
go
CREATE PROCEDURE [dbo].[CALL_ME]
#VAR VARCHAR(100)
AS
if OBJECT_ID('tempdb..#temp') is not null
begin
insert into #temp select #VAR
end
else
select #var value into #temp
select * from #temp
go
Please check if you have created the objects on the same DB or not.

I have this stored procedure which executes a lot of SQL queries and returns the results. How do i go about returning only the results from the queries that returns rows?
BEGIN
DECLARE #Query varchar(4000)
DECLARE cur CURSOR FOR SELECT SQLSyntax FROM tblChecks
OPEN cur
FETCH NEXT FROM cur INTO #Query
WHILE ##FETCH_STATUS = 0 BEGIN
EXEC (#Query)
FETCH NEXT FROM cur INTO #Query
END
CLOSE cur
DEALLOCATE cur
END
Please help me...
To avoid returning empty result sets, you have to conditionally run each query. For instance:
declare #query varchar(4000)
declare cur cursor local for
select 'if exists (' + SQLSyntax + ') ' + SQLSyntax from tblChecks
open cur
fetch next from cur into #query
while ##fetch_status = 0
begin
exec(#query)
fetch next from cur into #query
end
close cur
deallocate cur
Or, if every result set is identical, you could create a temp table first, and then insert all values into the temp table, and then do a single select statement at the end from the temp table:
create #temp (field1 type null, field2 type null, field3 type null)
declare #query varchar(4000)
declare cur cursor local for
select 'insert into #temp ' + SQLSyntax from tblChecks
open cur
fetch next from cur into #query
while ##fetch_status = 0
begin
exec(#query)
fetch next from cur into #query
end
close cur
deallocate cur
select * from #temp
drop table #temp
If possible, the 2nd option is better, because it will only run each query one time. The 1st option will run each query twice (that returns data), once to test if there are any results and once to return the data. This is not efficient! Hopefully all queries return the same fields in the results and you can use the 2nd option.
You can also execute and evaluate the results using the If exists strategy.
IF EXISTS(exec(#query))
BEGIN
exec(#query)
END
I got a table of words to be searched in the database and the table
Parameter
id Name Word
----------------------------------
1 word search c&a
2 word search Beton
3 word search Freiman
4 Anything Null
beside that i have the Procedure SearchAllTable, which is the searching Procedure and for searching the words in the database.
DECLARE #id int
DECLARE #name varchar(100)
DECLARE #word varchar(100)
DECLARE cur CURSOR FOR SELECT Id, word FROM #Parameter WHERE Name = 'word search'
OPEN cur
FETCH NEXT FROM cur INTO #id,#word
WHILE ##FETCH_STATUS = 0 BEGIN
EXEC SearchAllTables #word
FETCH NEXT FROM cur INTO #id, #word
END
CLOSE cur
DEALLOCATE cur
the problem that I got the result in multipule tables and I want them all to be listed in one table without any suppuration.
Insert your results into temporary table, created before cursor cycle
UPDATE
try this UNION the results of multiple stored procedures
Collect your result into a temp table or table variable and get it in a single select outside the cursor. Please try the bellow.
DECLARE #id int
DECLARE #name varchar(100)
DECLARE #word varchar(100)
--Create Result table wrt your SP output
DECLARE #Result TABLE (NAME VARCHAR(16), DATEVAL DATETIME)
DECLARE cur CURSOR FOR SELECT Id, word FROM #Parameter WHERE Name = 'word search'
OPEN cur
FETCH NEXT FROM cur INTO #id,#word
WHILE ##FETCH_STATUS = 0
BEGIN
INSERT INTO #Result
EXEC SearchAllTables #word
FETCH NEXT FROM cur INTO #id, #word
END
CLOSE cur
DEALLOCATE cur
--Selecting result as a single unit
SELECT * FROM #Result
How to truncate selective tables in SQL Server 2008,
I have a list of tables which may be excluded during truncate process.
Can anybody guide me?
You can simply run TRUNCATE TABLE yourTableName. If you have a list you can run the following:
CREATE TABLE #truncateTables(name nvarchar(255))
INSERT INTO #truncateTables(name) VALUES(N'dbo.yourTable1'),(N'dbo.yourTable2')
DECLARE cur CURSOR FOR
SELECT name FROM #truncateTables
OPEN cur
DECLARE #sql nvarchar(max), #tabname nvarchar(255)
FETCH NEXT FROM cur INTO #tabname
WHILE ##FETCH_STATUS = 0 BEGIN
SET #sql = N'TRUNCATE TABLE '+#tabname
BEGIN TRY EXEC(#sql)
END TRY
BEGIN CATCH -- if a foreign key constraint exists
SET #sql = N'DELETE FROM '+#tabname
EXEC(#sql)
END CATCH
FETCH NEXT FROM cur INTO #tabname
END
CLOSE cur
DEALLOCATE cur
DROP TABLE #truncateTables
I am using SQL Server 2012: This is the query using cursors.
create table test(id varchar(10), name varchar(10))
insert into test values('1','a'),('2','b'),('3','c')
declare #id varchar(10)
declare #name varchar(10)
declare cur cursor for
select id, name
from test
open cur
if ##CURSOR_ROWS > 0
begin
fetch next from cur into #id, #name
while ##FETCH_STATUS=0
begin
print 'test'
print #id+','+#name
fetch next from cur into #id,#name
end
end
close cur
deallocate cur
But in the result set it doesn't display results, but gets successfully executed.
Expected result
1,a
2,b
3,c
##CURSOR_ROWS is returning -1 that's why it's not printing.
Try this:
declare #id varchar(10)
declare #name varchar(10)
declare cur cursor for
select id, name from test
open cur
fetch next from cur into #id, #name
while ##FETCH_STATUS = 0
begin
print #id+','+#name
fetch next from cur into #id,#name
end
close cur
deallocate cur

I want to use cursor to delete record from table. How can I do it?
I use MSSQL 2008 Express this code does not delete anything from #temp. I also tried where current of cursor_name did not work.
Here is my sample code:
use AdventureWorks
drop table #temp
select * into #temp from HumanResources.Employee;
declare #eid as int;
declare #nid as varchar(15);
DECLARE Employee_Cursor CURSOR FOR
SELECT A.EmployeeID, A.NationalIDNumber FROM #temp AS A
OPEN Employee_Cursor;
FETCH NEXT FROM Employee_Cursor INTO #eid , #nid ;
WHILE ##FETCH_STATUS = 0
BEGIN
IF (#eid > 10)
BEGIN
delete from #temp where #temp.EmployeeID = #eid;
END
FETCH NEXT FROM Employee_Cursor;
END;
CLOSE Employee_Cursor;
DEALLOCATE Employee_Cursor;
GO
select * from #temp
thanks in advance
use AdventureWorks
select * into #temp from HumanResources.Employee;
declare #eid as int;
declare #nid as varchar(15);
DECLARE Employee_Cursor CURSOR FOR
SELECT A.EmployeeID, A.NationalIDNumber FROM #temp AS A
OPEN Employee_Cursor;
FETCH NEXT FROM Employee_Cursor INTO #eid , #nid ;
WHILE ##FETCH_STATUS = 0
BEGIN
IF (#eid > 10)
BEGIN
delete from #temp where current of Employee_Cursor
END
FETCH NEXT FROM Employee_Cursor INTO #eid , #nid ;
END;
CLOSE Employee_Cursor;
DEALLOCATE Employee_Cursor;
select * from #temp
drop table #temp
this works for me
There is a much simpler answer - use this command:
delete from HumanResources.Employee where current of Employee_Cursor
It's called 'Positioned delete' and described at MSDN.
Could you please try in below ways, thanks for your time.
You have fetched data from cursor but didn't push into your variables missed in WHILE loop, please have a look on below code, thanks.
drop table #temp
select * into #temp from Employee;
declare #eid as int;
declare #nid as varchar(15);
DECLARE Employee_Cursor CURSOR FOR
SELECT A.EmployeeID, A.NationalIDNumber FROM #temp AS A
OPEN Employee_Cursor;
FETCH NEXT FROM Employee_Cursor INTO #eid , #nid ;
WHILE ##FETCH_STATUS = 0
BEGIN
IF (#eid > 10)
BEGIN
delete from #temp where #temp.EmployeeID = #eid;
END
FETCH NEXT FROM Employee_Cursor INTO #eid , #nid ;
END;
CLOSE Employee_Cursor;
DEALLOCATE Employee_Cursor;
GO
select * from #temp
Update:
I've changes in 2nd FETCH statement, just have added below highlighted part, thanks
FETCH NEXT FROM Employee_Cursor INTO #eid , #nid ;
