I am trying to get all the data from a table and then clear all the data using a stored procedure. I tried the following:
ALTER PROCEDURE "RD1DTA"."my_procedure"()
BEGIN
SELECT * FROM rd1dta.qrtsp
TRUNCATE TABLE rd1dta.qrtsp
END
This only does the SELECT but it doesn't do the TRUNCATE. If I do the TRUNCATE before the SELECT then it does the TRUNCATE but not the SELECT. How do I get it to do both?
I am using sybase to do this.
Daniel,
Use a temp table:
ALTER PROCEDURE "RD1DTA"."my_procedure"()
BEGIN
SELECT * INTO #XYZ FROM rd1dta.qrtsp
TRUNCATE TABLE rd1dta.qrtsp
SELECT * FROM #XYZ
END
Hope that helps.

With the code:
SELECT *
FROM information_schema.tables
WHERE table_name LIKE 'prefix%';
I can obtain all the tables that I want to truncate, but how can I execute the TRUNCATE TABLE function for the results of that SELECT statement?
You cannot execute TRUNCATE from a SELECT statement. You could do something like
SELECT concat('TRUNCATE TABLE ',table_catalog,'.',table_schema,'.',table_name)
FROM information_schema.tables
WHERE table_name LIKE 'prefix%';
which would return a TRUNCATE statement for each table with the prefix. You could even look into using a stored procedure to execute each single row.
I use below code to create procedure to using temp table
Go
create procedure testTempTable
as
INSERT INTO #resultTbl (code,userName) SELECT code,userName FROM Customer
select * from #resultTbl
Go
When I want to run the procedure with exec testTempTable says
Invalid object name '#resultTbl'.
How can I use temp table in the procedure?
Because your temp table might not be created, so you can't get result set from #resultTbl. you can try to use SELECT ... INTO temp table or create a temp table before you use it.
create procedure testTempTable
as
BEGIN
SELECT code,userName
INTO #resultTbl
FROM Customer
SELECT *
FROM #resultTbl
END
Go
I know the temporary table will be deleted after the connection is lost. But within that connection, I want to do something like
EXEC test;
SELECT * FROM #Final;
#Final is the temporary table created in the stored procedure. The stored procedure needs 30 seconds, and I want to check my #final without running stored procedure again.
If I run the script in that stored procedure, the #final can be reused in the connection. But how to use it after the EXEC test?
So, except for creating a real table, is it possible to SELECT * FROM #Final after EXEC test? If no, I'll use real table instead. Thanks!
Then you don't want a temporary table. Use either a global temporary table (##final) or a real table.
Then delete the results after you run the procedure.
I should note that the stored procedure can return a result set which you can insert into a table, using exec().
Use a global temporary Table
create proc demo as
begin
select * into ##temptable from original_table
end
exec demo;
select * from ##temptable
SELECT Val from storedp_Value within the query editor of SQL Server Management Studio, is this possible?
UPDATE
I tried to create a temp table but it didn't seem to work hence why I asked here.
CREATE TABLE #Result
(
batchno_seq_no int
)
INSERT #Result EXEC storedp_UPDATEBATCH
SELECT * from #Result
DROP TABLE #Result
RETURN
Stored Procedure UpdateBatch
delete from batchno_seq;
insert into batchno_seq default values;
select #batchno_seq= batchno_seq_no from batchno_seq
RETURN #batchno_seq
What am I doing wrong and how do I call it from the query window?
UPDATE #2
Ok, I'd appreciate help on this one, direction or anything - this is what I'm trying to achieve.
select batchno_seq from (delete from batchno_seq;insert into batchno_seq default values;
select * from batchno_seq) BATCHNO
INTO TEMP_DW_EKSTICKER_CLASSIC
This is part of a larger select statement. Any help would be much appreciated. Essentially this SQL is broken as we've migrated for Oracle.
Well, no. To select from a stored procedure you can do the following:
declare #t table (
-- columns that are returned here
);
insert into #t(<column list here>)
exec('storedp_Value');
If you are using the results from a stored procedure in this way and you wrote the stored procedure, seriously consider changing the code to be a view or user defined function. In many cases, you can replace such code with a simpler, better suited construct.
This is not possible in sql server, you can insert the results into a temp table and then further query that
CREATE TABLE #temp ( /* columns */ )
INSERT INTO #temp ( /* columns */ )
EXEC sp_MyStoredProc
SELECT * FROM #temp
WHERE 1=1
DROP TABLE #temp
Or you can use OPENQUERY but this requires setting up a linked server, the SQL is
SELECT * FROM (ThisServer, 'Database.Schema.ProcedureName <params>')
The best article (in my opinion) about all possible methods for sharing data between stored procedures in SQL Server you can find here: http://www.sommarskog.se/share_data.html
Try this
Change 'Return'
delete from batchno_seq;
insert into batchno_seq default values;
select #batchno_seq= batchno_seq_no from batchno_seq
RETURN #batchno_seq
to 'Select'
delete from batchno_seq;
insert into batchno_seq default values;
select #batchno_seq= batchno_seq_no from batchno_seq
SELECT #batchno_seq
My approach
select * into new_table from (select t1.col1,t1.col2,..
from table1 t1
union
select t2.cola,t2.colb,..
from table2 t2) as union_table
I MUST be missing something.
Since your stored procedure does not return a result set, and instead returns an integer, using the RETURN functionality of stored procs, you simply CANNOT INSERT into ANY table (since there isn't any result set coming back, at all).
BUT, you can (assuming that this is done iteratively, and not over a set) simply store the return value into a local variable, and insert that variable's value into whatever table is necessary.
However, if you simply want to return the value in the results of a Query Window in SSMS, doing the INSERT and SELECTING is overkill.
It seems to me like THIS would suffice (in a query window):
DECLARE #RetVal INT = 0;
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
EXEC #RetVal = storedp_UPDATEBATCH;
COMMIT TRANSACTION;
SELECT #RetVal;
--OR
--PRINT #RetVal;
If this is way far off base, please provide the DDL for "batchno_seq", maybe I can be of better assistance that way.
Cheers!
I am trying to write a stored procedure in SQL Server 2008 which updates a table after some values are inserted into the table.
My stored procedure takes the values from a DMV and stores them in a table. In the same procedure after insert query, I have written an update query for the same table.
Insert results are populated fine, but the results of updates are getting lost.
But when I try to do only inserts in the stored procedure and I execute the update query manually everything is fine.
Why it is happening like this?
there should not be a problem in this.
below code working as expected.
create procedure dbo.test
as
begin
create table #temp (
name varchar(100) ,
id int
)
insert #temp
select name ,
id
from master..sysobjects
update #temp
set name='ALL Same'
from #temp
select * from #temp
drop table #temp
end
go
Best approach is to use Trigger, sample of AFTER UPDATE trigger is below:
ALTER TRIGGER [dbo].[tr_MyTriggerName]
ON [dbo].[MyTableName] AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
--if MyColumnName is updated the do..
IF UPDATE (MyColumnName)
BEGIN
UPDATE MyTableName
SET AnotherColumnInMyTable = someValue
FROM MyTableName
INNER JOIN Inserted
ON MyTableName.PrimaryKeyColumn = Inserted.PrimaryKeyColumn
END
END
