I am having a little trouble with my after insert trigger it does not update/insert into the table and I am not sure why.
I have the tables employee, position, certification, employeecertification, positioncertification.
What I need to do is after a Position is assigned a Certification then all employees that are defined in that position (Employee:PositionId = Ins.PositionId] need to get the certification added (if it does not already exist in their record) , I might need to update them where they do exist (but for the moment do not believe that will be a requirement).
I have been getting a couple different results (neither is correct)
1: EmployeeId can not insert null into EmployeeId
2: On some other test data - nothing is inserted.
I have the following trigger with the sql for creation of tables that follows:
The Trigger
CREATE TRIGGER [dbo].[trig_InsNew_PositionCertification]

Left Join dbo.Employee Emp On Emp.PositionId = Ins.PositionId
Left Join dbo.Certification Trw On Trw.CertificationId = Ins.CertificationId
WHERE NOT EXISTS
(SELECT EmployeeId, CertificationId
FROM
EmployeeCertification
WHERE EmployeeId = Emp.EmployeeId AND CertificationId = Ins.CertificationId);

I have been working with SQL for 3 month, I would like to know create a table with 3 columns as primary key, Any help would be great thank you.
This code below is a Scrip to Create table generated my SQL Server Management Studio of the table
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[REP]
(
[id] [UNIQUEIDENTIFIER] ROWGUIDCOL NOT NULL,
[id_client] [NCHAR](30) NULL,
[id_representant] [UNIQUEIDENTIFIER] NULL,
[date_debut] [DATE] NULL,
[date_fin] [DATE] NULL,
CONSTRAINT [PK_REP]
PRIMARY KEY CLUSTERED ([id] ASC)
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,
IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,
ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
ALTER TABLE [dbo].[REP]
ADD CONSTRAINT [DF_REP_id] DEFAULT (NEWID()) FOR [id]
GO
First all the columns that are part of the primary key have to be not null.
then defining the key just add all columns as comma separated list.
CREATE TABLE [dbo].[REP](
[id] [uniqueidentifier] ROWGUIDCOL NOT NULL,
[id_client] [nchar](30) NOT NULL,
[id_representant] [uniqueidentifier] NULL,
[date_debut] [date] NULL,
[date_fin] [date] NULL,
CONSTRAINT [PK_REP] PRIMARY KEY CLUSTERED
( [id] ASC,id_client ASC )
WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY]
In the code above I changed the column id_client to be not null and added it to the definition of the primary key ... ([id] ASC, id_client ASC).
To add more columns to a primary Key contraint you'd add the additional fields after the first field.
[id] ASC, nextfield ASC, nextfield2 asc
You can have a one composite key that comprise of more than one primary key.
CREATE TABLE xyz (
primary key (id,id_client,id_representer)
);
I have two tables which is one of them is
AI: Ascent insensitive and other is AS: Ascent sensitive
How can I compare between them and take difference between them? I used except
select ID,FIRST,FATHER,GRAND from t1
EXCEPT
select ID,FIRST,FATHER,GRAND from t2
But I got this error:
Cannot resolve the collation conflict between "Arabic_CI_AS" and
"Arabic_100_CI_AI" in the EXCEPT operation
Choose an appropriate collation so that the comparison of the strings does match as wanted (e. G. "CI" = case sensitive/insensitive), the use your collation like this (ignoring the problem of of the ID column in EXCEPT:
select ID,
FIRST collate Arabic_CI_AS,
FATHER collate Arabic_CI_AS,
GRAND collate Arabic_CI_AS
from t1
EXCEPT
select ID,
FIRST collate Arabic_CI_AS,
FATHER collate Arabic_CI_AS,
GRAND collate Arabic_CI_AS
from t2
it working here

The problem
During the passed few months the below described procedure has worked without any problems a vast majority of the times it has run (on 2008 r2). We have, however, three instances of incorrectly connected data. The question is, what is causing this and how do I remedy it?
DATA_PreImp
sourceid col01 col02 col03 col04 col...
100001 John Smith
100002 Calvin Klein
100003 Peter Parker
100004 Moe Greene
Usually the rendered result is that the attribute is connected to the Items_Main correctly but sometimes (less than 1%) the order is scrambled so that the value of col01 is not connected to the same Items_Main as the value of the rest of the columns.
Any insights as to what is causing this would be most appreciated.
The data moving procedure
We have an SSIS package that transfers data from a flat table called DATA_PreImp to a structure consisting of three related tables (attribute based).
Items_Main should contains one row for each row in DATA_PreImp
Items_Featurevalues contains one row for each column value of a row in DATA_PreImp
Items_MainRel contains the connection between Items_Main and Items_FeatureValues
The first step in the SSIS package inserts the data from DATA_PreImp to Items_Main and inserts the generated identifier into the TARGET_ID column in the empty DATA_PreImpMappingTMP table.
insert into items_main(creationdate, status)
output inserted.itemid into DATA_PreImpMappingTMP(TARGET_ID)
select getdate(), '0' from data_preimp
order by sourceid asc;
The second step in the SSIS package fill the Items_MainRel table with TARGET_ID (Itemid originally) and an identifier for the feature (in this case a 5).
insert into items_mainrel(itemid, featureid)
output inserted.itemrelid into DATA_PreImpMapping2TMP(INDREL_ID)
select TARGET_ID, 5 from DATA_PreImpMappingTMP
order by TARGET_ID asc;
The third step is to fill the SOURCE_ID column in the DATA_PreImpMapping2TMP table with the SOURCE_ID from DATA_PreImp.
with cte as (select sourceid, row_number() over (order by sourceid asc) as row from data_preimp)
update m set m.SOURCE_ID = s.sourceid, m.FEAT_ID = 5
from DATA_PreImpMapping2TMP as m
join cte as s on s.row = m.ROW;
The last step is to fill the Items_FeatureValues table with data from DATA_PreImpMapping2TMP and DATA_PreImp.
insert into items_featurevalues(itemrelid, languageid, fnvarchar)
select DATA_PreImpMapping2TMP.INDREL_ID, 0, data_preimp.col01
from DATA_PreImpMapping2TMP
join data_preimp on (DATA_PreImpMapping2TMP.SOURCE_ID = data_preimp.sourceid)
where FEAT_ID = 5

The problem was the computed column CUST_CD. After a lot of researching, it seems that the BULK INSERT does not like complex computed types (see Using SQL Server spatial types in SSIS data load). The solution is to removed the computed column and just make it a varchar(20) NULL. Then I created a new Execute SQL Task that updates any NULL rows with the computed value.
I wish to migrate some data from a single table into these new THREE tables.
Here's my destination schema:
Notice that I need to insert into the first Location table .. grab the SCOPE_IDENTITY() .. then insert the rows into the Boundary and Country tables.
The SCOPE_IDENTITY() is killing me :( meaning, I can only see a way to do this via CURSORS. Is there a better alternative?
UPDATE
Here's the scripts for the DB Schema....

I don't see a need for SCOPE_IDENTITY or cursors if you approach the data in order of the parent/child relationship:
INSERT INTO LOCATION
SELECT t.name,
t.originallocationid
FROM ORIGINAL_TABLE t
GROUP BY t.name, t.originallocationid
INSERT INTO COUNTRY
SELECT DISTINCT
t.isocode,
l.locationid
FROM ORIGINAL_TABLE t
JOIN LOCATION l ON l.name = t.name
AND l.originallocationid = t.originalocationid
INSERT INTO BOUNDARY
SELECT DISTINCT
l.locationid,
t.centrepoint,
t.originalboundary,
t.largereducedboundary,
t.mediumreducedboundary,
t.smallreducedboundary
FROM ORIGINAL_TABLE t
JOIN LOCATION l ON l.name = t.name
AND l.originallocationid = t.originalocationid
After loading your Location table you could create a query that joins Location with your source single table. The join criteria would be the natural key (is that the Name column?) and it would return the new LocationId along with the Boundary data. The results would inserted into the new Boundary table.
