I want to transfer data of table A,column emp_name to Table B with column name EMP_NAME.
I want that EMP_ID column of Table B to be equal to row_id.How this can be done in sql
or ssis..?
what have you tried?
You will need two connections, one for each DB and one data flow component which will have a OleDBSource and an OleDBDestination component inside.
On the OleDBSource you can select your connection and write your query and then you drag the green arrow to the OleDBDestination. Double click the OleDBDestination select destination connection and table and click on mapping.
Should be it
SQL:
SELECT ROW_NUMBER() OVER(ORDER BY emp_name DESC) AS 'emp_id on table B', emp_name
FROM table
The SQL is:
INSERT INTO
TableB (EMP_ID, EMP_NAME)
SELECT
A.row_id
A.emp_name
FROM
TableA AS A
but for this to work EMP_ID on TableB must not be defined as an IDENTITY column (assuming you are in SQL Server).

Consider the following relational data table, employee. Now find the output for the following SQL statement?
SELECT COUNT(*)
FROM employee, employee, employee
Employee table
gid
name
Three
E101
John
HRM
E102
Lucy
Marketing
E103
Rick
Management
This will produce error since you didn't use unique aliases. You need to assign unique name (alias) to all the tables in from clause. But you should run it first. Here I am sharing a fiddle link please go there and run the query.
Schema (MySQL v5.7)
create table employee (gid varchar(20), name varchar(20),Three varchar(20));
insert into employee values('E101','John','HRM');
insert into employee values('E102','Lucy','Marketing');
insert into employee values('E103','Rick','Management');
Query #1
SELECT count(*) From employee a, employee b, employee c;
count(*)
27

I'm having an issue copying one table's data to another. I have around 100 or so individual tables that have generally the same field names but not always. I need to be able to copy and map the fields. example: source table is BROWARD and has column names broward_ID, name, dob, address (the list goes on). The temp table I want to copy it to has ID, name, dob, address etc.
I'd like to map the fields like broward_ID = ID, name = name, etc. But many of the other tables are different in column name, so I will have to write a query for each one. Once I figure out the first on, I can do the rest. Also the column in both tables are not in order either..thanks in advance for the TSQL...
With tables:
BROWARD (broward_ID, name, dob, address) /*source*/
TEMP (ID, name, address,dob) /*target*/
If you want to copy information from BROWARD to TEMP then:
INSERT INTO TEMP SELECT broward_ID,NAME,ADDRESS,DOB FROM BROWARD --check that the order of columns in select represents the order in the target table
If you want only copy values of broward_ID and name then:
INSERT INTO TEMP(ID, name) SELECT broward_ID,NAME FROM BROWARD
Your question will resolve using update
Let's consider we have two different table
Table A
Id Name
1 abc
2 cde
Table B
Id Name
1
2
In above case want to insert Table A Name column data into Table B Name column
update B inner join on B.Id = A.Id set B.Name = A.Name where ...
i have an employee database table with a column NAME
in the NAME field we have names of employees like this -> LI-MING (ALLEN)
this is there real first name and there English nick name in ()
i would like to know if i can swap this around in an SQL UPDATE query
FROM: LI-MING (ALLEN) TO: ALLEN (LI-MING)
the reason why i would like this is Users want to have it sort this column by nick name
Try this
UPDATE Employee
SET NAME =
SUBSTRING(name,CHARINDEX('(',name)+1,(CHARINDEX(')',name)-CHARINDEX('(',name)-1))+
' ('+SUBSTRING(name,1,CHARINDEX('(',name)-1)+')'
FROM Employee
If I were you I would create seperate colums both for name and nick name. Trying to get a string portion on the fly prevent sql server from using indexes which might be really importand from performance perspective.
So there are basicly two options:
Parse values for seperate columns every time you update or insert a new employee (via TRIGGER, application code, etc).
Or just create two calculated columns but make sure they are marked as PERSISTED.
Hope it helps!
I had worked on several project and I have done it my way to update same issue that you been through in 3 steps:
1) Create table with ID or Name field and Insert the values to the table
2) Trim the values with different functions and insert the final value to different table.
3) Update the old table with the new value
I don't say this is the only way to do thing but there might be other ways as well.
Create table #Employee(
EmployeeName varchar(200)
)
Insert into #Employee
Select 'LI-MING (ALLEN)' union all
Select 'Jio-Kio (Smith)'
Select
substring(employeename,1,patindex('%(%',employeename)-1),
--Len(substring(employeename,1,patindex('%(%',employeename)-1)),
Right(employeename,len(employeename)-(len(substring(employeename,1,patindex('%(%',employeename)))))
from #Employee
Create table #EmployeeNew(
Employeename1 varchar(200),
Employeename2 varchar(200)
)
Insert into #EmployeeNew(Employeename1, Employeename2)
Select
ltrim(rtrim(substring(employeename,1,patindex('%(%',employeename)-1))),
ltrim(rtrim(Right(Employeename,charindex('(',employeename,1)-3)))
from #Employee
Select * from #Employee
Select * from #EmployeeNew
Select cast('('+Employeename1+')'+left(employeename2,len(employeename2)-1) as varchar(200)) from #EmployeeNew
Update e
Set e.EmployeeName = cast('('+e1.Employeename1+')'+left(e1.employeename2,len(e1.employeename2)-1) as varchar(200))
from #Employee e
left outer join #EmployeeNew e1 on ltrim(rtrim(substring(e.employeename,1,patindex('%(%',e.employeename)-1))) =e1.Employeename1
Sorry for the lack of info -- SQL Server 2008.
I'm struggling to get a couple of column values from table A into a new row in table B for each row in A where a column isn't null.
Table A's structure is as:
UserID | ClientUserID | ClientSessionID | [and a load of other irrelevant columns)
Table B:
UserID | Name | Value
I want to create rows in table B for each non-null ClientUserID or ClientSessionID in A - using the column name as B's "Name", and column value as "B's Value".
I'm struggling to write my "unpivot" statement - just getting the syntax correct! I'm trying to follow along with some samples but can't
Here's my SQL query so far - any further help would be appreciated (just getting this SELECT is frustrating me, let alone doing the insert!)
SELECT UserID, ClientUserID, ClientSessionID FROM websiteuser WHERE ClientSessionID IS NOT null
This gives me the rows that I need to perform actions upon -- but I just can't get the syntax correct for UNPIVOTing this data and turning it into my insert.
You can unpivot records in this fashion by using UNION to get each new row:
INSERT INTO TableB (UserID, Name, Value)
SELECT UserID, 'ClientUserID' AS Name, ClientUserID AS Value
FROM TableA
WHERE ClientUserID IS NOT NULL
UNION ALL
SELECT UserID, 'ClientSessionID' AS Name, ClientSessionID AS Value
FROM TableA
WHERE ClientSessionID IS NOT NULL
I am using UNION ALL in this case as UNION implies a DISTINCT operation across the entire set, which should normally be unnecessary when pivoting unique records.
If your ClientUserID and ClientSessionID columns are not the same datatype, you may have to cast one or both to the same.
I have a table known as Customer(DATABASE AAA) containing 3 fields
Cust_id Cust_name Cust_salary
1 A 2000
2 B 3000
3 C NULL
I want to put data of these 3 columns in Employee(DATABASE BBB) which has the same structure as of Customer.
I want to transfer records of only those customer in which Cust_salary part is not null.
This work is to be done in SSIS only. MY values for Cust_id is auto generated & before putting values to Employee_id,the Employee table should be deleted.The auto generated identity should be preserved.
You could create a SQL Execute Task in SSIS and run the following:
INSERT INTO Employee
(EmployeeId, EmployeeName, EmployeeSalary)
SELECT Cust_id, Cust_name, Cust_salary
FROM Customer
WHERE Cust_salary IS NOT NULL
Darren Davies answer seems correct, but if for some obscure reason you have an EmployeeID is also an identity column and needs to match Cust_ID, and assuming any entries already in the Employee table correspond with the correct customer you can use an Execute SQL Task in SSIS with a connection open to Database BBB to run the following:
SET IDENTITY_INSERT Employee ON
INSERT INTO Employee (EmployeeID, EmployeeName, EmployeeSalary)
SELECT Cust_ID, Cust_Name, Cust_Salary
FROM AAA..Customer
WHERE Cust_Salary IS NOT NULL
AND NOT EXISTS
( SELECT 1
FROM Employee
WHERE EmployeeID = Cust_ID
)
SET IDENTITY_INSERT Employee OFF
This will maintain the integrity of the Identity fields in each table, and only insert new Customers to the Employee table.
