I'm trying to get the rows affected output from an sql server stored procedure activity in azure data factory to azure log analytics. I can currently get the rowsCopied and rowsRead from the copy activity. Would appreciate any help.
Below is the sample code in determining the effected rows from stored procedure in SQL server
CREATE PROCEDURE UpdateTables
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
DECLARE #RowCount1 INTEGER
DECLARE #RowCount2 INTEGER
DECLARE #RowCount3 INTEGER
DECLARE #RowCount4 INTEGER
UPDATE Table1 Set Column = 0 WHERE Column IS NULL
SELECT #RowCount1 = ##ROWCOUNT
UPDATE Table2 Set Column = 0 WHERE Column IS NULL
SELECT #RowCount2 = ##ROWCOUNT
UPDATE Table3 Set Column = 0 WHERE Column IS NULL
SELECT #RowCount3 = ##ROWCOUNT
UPDATE Table4 Set Column = 0 WHERE Column IS NULL
SELECT #RowCount4 = ##ROWCOUNT
SELECT #RowCount1 AS Table1, #RowCount2 AS Table2, #RowCount3 AS Table3, #RowCount4 AS Table4
END

Following is the procedure that i have written in my application. But i want the LogSource Column in my list, but i am not able to get it from this stored procedure.
CREATE PROCEDURE [dbo].[GetApplicationLogs]
-- Add the parameters for the stored procedure here
#Skip int,
#Pagesize int
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
WITH TableDatawithRowNumber AS
( SELECT dbo.ApplicationLog.* ,ROW_NUMBER() OVER (ORDER BY LoggedDate DESC) AS RowNumber,
(SELECT COUNT(*) AS Expr1
FROM ApplicationLog ) AS TotalRecords
from ApplicationLog
)
SELECT * FROM TableDatawithRowNumber
WHERE RowNumber > #Skip AND RowNumber <= (#Pagesize+#Skip)
END
This table doensn't contain a LogSource column but it is having LogSourceID in it which is a foreign key in this table and the primary key in LogSource Table. I want to show that in my list but i am not able to get it in the view. I can only use LogSourceId but not LogSource. So please help me.
I think you just need to do a left join on the LogSource table
WITH TableDatawithRowNumber AS
( SELECT dbo.ApplicationLog.* ,ROW_NUMBER() OVER (ORDER BY LoggedDate DESC) AS RowNumber, logSource.LogSource
(SELECT COUNT(*) AS Expr1
FROM ApplicationLog ) AS TotalRecords
from ApplicationLog as appLog
left join LogSource as logSource on appLog.LogSourceId = logSource.LogSourceId
)
I have a stored procedure for Oracle 10g that needs to create a new row in the table and not create duplicates.
The table allows duplicates, so long as all columns are not the same. This is because the last two columns can differ in values.
With that being said, when I try to store my procedure I get the following flags:
Line # = 10 Column # = 1 Error Text = PL/SQL: SQL Statement ignored
Line # = 13 Column # = 3 Error Text = PL/SQL: ORA-00933: SQL command not properly ended
The procedure looks fine [given I haven't added a WHERE clause for an insert before like this].
So either my format isn't what it should be or my logic is off.
Whatever the case may be, I have tried finding examples online and on stackoverflow and have fallen short.
Any suggestions on how I should tweak this?
(val_ID tablename.column1%type,
val_cat tablename.column2%type,
val_sub tablename.column3%type
)
AS
BEGIN
INSERT INTO tablename (column1, column2, column3)
VALUES (val_ID, val_cat, val_sub)
WHERE ((column1 != val_ID) and (column2 != val_cat) and (column3 != val_sub));
COMMIT;
END;
I have even removed the "(" in WHERE clause and nothing changed.
UPDATE:
tried the suggestion and all errors are gone [however the record didn't create]
(val_ID tablename.column1%type,
val_cat tablename.column2%type,
val_sub tablename.column3%type
)
AS
BEGIN
INSERT INTO tablename (column1, column2, column3)
SELECT val_ID, val_cat, val_sub
FROM dual
MINUS
SELECT val_ID, val_cat, val_sub
FROM tablename;
The insert statement doesn't have a where clause. You could emulate it, though, by using an insert-select statement:
INSERT INTO tablename (column1, column2, column3)
SELECT val_ID, val_cat, val_sub
FROM dual
MINUS
SELECT column1, column2, column3
FROM tablename;
#Mureinik 's example did negate all my errors; however, when tested it didn't create the new row.
So my current work around will be a query in VB.net checking if the value exists and then implementing a simple insert stored procedure:
//Make select statement and look at table for whether more than 0 rows shows up. If 0 rows, then execute stored procedure
If DsAds1.Tables(0).Rows.Count = 0 Then
...do stored procedure
End If
Stored Procedure
(val_ID tablename.column1%type,
val_cat tablename.column2%type,
val_sub tablename.column3%type
)
AS
BEGIN
INSERT INTO tablename (column1, column2, column3)
VALUES( val_ID, val_cat, val_sub);
COMMIT;
END;
I am intended to insert data in multiple tables and for each entry I need to capture SCOPE_IDENTITY() for each insert. In my store procedure, it store record for first insert and return SCOPE_IDENTITY() but following insert does not record value unless I remove SCOPE_IDENTITY()... what I am doing wrong here ????
I am using SQL Server 2012
USE [MySolution01_DB]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[CreateNewFunctionsNavigation]
#FunctionName nvarchar(250),
#Hierarchy_Level INT,
#Function_identity INT OUTPUT,
#ControllerName nvarchar(250),
#Controller_identity INT OUTPUT
AS
BEGIN
SET NOCOUNT ON;
INSERT INTO [dbo].[Navigation_Functions] ([FunctionName],[Hierarchy_Level] )
VALUES(#FunctionName, #Hierarchy_Level)
SET #Function_identity=SCOPE_IDENTITY()
RETURN #Function_identity
INSERT INTO [dbo].[Navigation_FunctionController] ([ControllerName])
VALUES(#ControllerName)
SET #Controller_identity = SCOPE_IDENTITY()
RETURN #Controller_identity
RETURN
END
I would like to change a couple of column values before they get inserted.
I am using Informix as database.
I have a table consisting of 3 columns: Name (NVARCHAR), Type (INT), Plan (NVARCHAR).
Every time a new record is inserted, I would like to check the Name value before inserting it. If the Name starts with an F, I would like to set the Type value to 1 and the Plan Name to "Test"
In short, what I want the trigger to do is:
For every new insertion, first check if Name value starts with F.
If yes, set the Type and Plan to 1 and "Test" then insert.
If no, insert the values as-is.
I have looked up the CREATE TRIGGER statement with BEFORE and AFTER. However, I would like to have a clearer example. My case would probably involve BEFORE though.
The answer of #user3243781 get close, but did not work because it returns the error:
-747 Table or column matches object referenced in triggering statement.
This error is returned when a triggered SQL statement acts on the
triggering table, or when both statements are updates, and the column
that is updated in the triggered action is the same as the column that
the triggering statement updates.
So the alternative is handle with the NEW variable directly.
For that you need to use a procedure with the triggers reference resource, which means the procedure will able to act like the trigger by self.
Below is my example which I run with dbaccess over a Informix v11.70.
This resource is available only for versions +11 of the engine, as far I remember.
create table teste ( Name NVARCHAR(100), Type INT , Plan NVARCHAR(100) );
Table created.
create procedure check_name_values()
referencing new as n for teste ;;
define check_type integer ;;
define check_plan NVARCHAR ;;
if upper(n.name) like 'F%' then
let n.type = 1;;
let n.plan = "Test";;
end if
end procedure ;
Routine created.
;
create trigger trg_tablename_ins
insert on teste
referencing new as new
for each row
(
execute procedure check_name_values() with trigger references
);
Trigger created.
insert into teste values ('cesar',99,'myplan');
1 row(s) inserted.
insert into teste (name) values ('fernando');
1 row(s) inserted.
insert into teste values ('Fernando',100,'your plan');
1 row(s) inserted.
select * from teste ;
name cesar
type 99
plan myplan
name fernando
type 1
plan Test
name Fernando
type 1
plan Test
3 row(s) retrieved.
drop table if exists teste;
Table dropped.
drop procedure if exists check_name_values;
Routine dropped.
create trigger trg_tablename_ins
insert on tablename
referencing new as new
for each row
(
execute procedure check_name_values
(
new.name,
new.type,
new.plan
)
);
create procedure check_name_values
(
name NVARCHAR,
new_type integer,
new_plan NVARCHAR,
)
define check_type integer ;
define check_plan NVARCHAR ;
let check_type = 1;
let check_plan = "Test";
if name = 'F%'
then
insert into tablename (name,type,plan) values (name,check_type,check_plan);
else
insert into tablename (name,type,plan) values (name,new_type,new_plan);
end if ;
end procedure ;
Here is my version an adaptation of an old example I found in the informix usenet group.
It is possible to update columns in a trigger statement but not very straight forward. You have to use stored procedures an the into statement with the execute procedure command.
It worked here for IBM Informix Dynamic Server Version 12.10.FC11WE.
drop table if exists my_table;
drop sequence if exists my_table_seq;
create table my_table (
id INTEGER
NOT NULL,
col_a char(32)
NOT NULL,
col_b char(20)
NOT NULL,
hinweis char(64),
uslu char(12)
DEFAULT USER
NOT NULL,
dtlu DATETIME YEAR TO SECOND
DEFAULT CURRENT YEAR TO SECOND
NOT NULL
)
;
create sequence my_table_seq
increment 1
start 1;
drop procedure if exists get_user_datetime();
create function get_user_datetime() returning char(12),datetime year to second;
return user, current year to second;
end function
;
drop trigger if exists ti_my_table;
create trigger ti_my_table insert on my_table referencing new as n for each row (
execute function get_user_datetime() into uslu, dtlu
)
;
drop trigger if exists tu_my_table;
create trigger tu_my_table update on my_table referencing new as n for each row (
execute function get_user_datetime() into uslu, dtlu
)
;
insert into my_table values (my_table_seq.nextval, "a", "b", null, "witz", mdy(1,1,1900)) ;
SELECT *
FROM my_table
WHERE 1=1
;
I am writing a PL/SQL stored procedure which will be called from within a .NET application.
My stored procedure must return
the count of values in a table of part revisions, based on an input part number,
the name of the lowest revision level currently captured in this table for the input part number
the name of the revision level for a particular unit in the database associated with this part number and an input unit ID.
The unit's revision level name is captured within a separate table with no direct relationship to the part revision table.
Relevant data structure:
Table Part has columns:
Part_ID int PK
Part_Number varchar2(30)
Table Part_Revisions:
Revision_ID int PK
Revision_Name varchar2(100)
Revision_Level int
Part_ID int FK
Table Unit:
Unit_ID int PK
Part_ID int FK
Table Unit_Revision:
Unit_ID int PK
Revision_Name varchar2(100)
With that said, what is the most efficient way for me to query these three data elements into a ref cursor for output? I am considering the following option 1:
OPEN cursor o_Return_Cursor FOR
SELECT (SELECT COUNT (*)
FROM Part_Revisions pr
inner join PART pa on pa.part_id = pr.part_id
WHERE PA.PART_NO = :1 )
AS "Cnt_PN_Revisions",
(select pr1.Revision_Name from Part_Revisions pr1
inner join PART pa1 on pa1.part_id = pr1.part_id
WHERE PA.PART_NO = :1 and pr1.Revision_Level = 0)
AS "Input_Revison_Level",
(select ur.Revision_Name from Unit_Revision ur
WHERE ur.Unit_ID = :2) as "Unit_Revision"
FROM DUAL;
However, Toad's Explain Plan returns Cost:2 Cardinality: 1, which I suspect is due to me using DUAL in my main query. Comparing that to option 2:
select pr.Revision_Name, (select count(*)
from Part_Revisions pr1
where pr1.part_id = pr.part_id) as "Count",
(select ur.Revision_Name
from Unit_Revision ur
where ur.Unit_ID = :2) as "Unit_Revision"
from Part_Revisions pr
inner join PART pa on pa.part_id = pr.part_id
WHERE PA.PART_NO = :1 and pr.Revision_Level = 0
Essentially I don't really know how to compare the results from my execution plans, to chose the best design. I have also considered a version of option 1, where instead of joining twice to the Part table, I select the Part_ID into a local variable, and simply query the Part_Revisions table based on that value. However, this is not something I can use the Explain Plan to analyze.
Your description and select statements look different... I based the procedure on the SQL statements.
PROCEDURE the_proc
(
part_no_in IN NUMBER
, revision_level_in IN NUMBER
, unit_id_in IN NUMBER
, part_rev_count_out OUT NUMBER
, part_rev_name_out OUT VARCHAR2
, unit_rev_name_out OUT VARCHAR2
)
AS
BEGIN
SELECT COUNT(*)
INTO part_rev_count_out
FROM part pa
WHERE pa.part_no = part_no_in
AND EXISTS
(
SELECT 1
FROM part_revisions pr
WHERE pa.part_id = pr.part_id
);
SELECT pr1.revision_name
INTO part_rev_name_out
FROM part_revisions pr1
WHERE pr1.revision_level = revision_level_in
AND EXISTS
(
SELECT 1
FROM part pa1
WHERE pa1.part_id = pr1.part_id
AND pa.part_no = part_no_in
);
SELECT ur.revision_name
INTO unit_rev_name_out
FROM unit_revision ur
WHERE ur.unit_id = unit_id_in;
END the_proc;
It looks like you are obtaining scalar values. Rather than return a cursor, just return the values using clean sql statements. I have done this numerous times from .net, it works fine.
Procedure get_part_info(p_partnum in part.part_number%type
, ret_count out integer
, ret_revision_level out part_revisions.revision_level%type
, ret_revision_name out part_revisions.revision_name%type) as
begin
select count(*) into ret_count from ....;
select min(revision_level) into ret_revision_level from ...;
select revision_name in ret_revision_name...;
return;
end;
