I am trying to insert data to a table from another where data is not already exists
The table I am inserting the data into
CREATE TABLE #T(Name VARCHAR(10),Unit INT, Id INT)
INSERT INTO #T
VALUES('AAA',10,100),('AAB',11,102),('AAC',12,130)
The table I am selecting the data from
CREATE TABLE #T1(Name VARCHAR(10),TypeId INT,Unit INT, Id INT)
INSERT INTO #T1
VALUES('AAA',3,10,100),('AAA',3,10,106)
In this case I want to select ('AAA',3,10,106) from #T1 because AAA,106 combination not exists in #T
Basically what I want is to populate unique Name and Id combination
I tried below which doesn't seems to work
SELECT *
FROM #T1
WHERE NOT EXISTS(SELECT * FROM #T)
You have to somehow correlate the two tables:
SELECT *
FROM #T1
WHERE NOT EXISTS(SELECT *
FROM #T
WHERE #T1.Name = #T.Name AND #T1.ID = #T.ID)
The above query essentially says: get me those records of table #T1 which do not have a related record in #T having the same Name and ID values.
Your best bet is probably to use a insert statement with a subquery. Something like this:
SQL Insert Into w/Subquery - Checking If Not Exists
Edit: If you're still stuck, try this--
INSERT INTO #T (Name, Unit, Id)
SELECT Name, Unit, Id
FROM #T1
WHERE
NOT EXISTS (SELECT Name, Unit, Id FROM #T
WHERE #T.Name = #T1.Name AND #T.Unit = #T1.Unit AND #T.Id = #T1.Id)

I have this function, but I wanted to pass a table so as to use the same function to get the job done for multiple tables. For example, I want this function work for table1, and table2. But it is just for table1 currently. I was trying to use a dynamic sql in vain; it doesn't pass the parameter selected.
Can someone help? Give me guide on how to pass table as a parameter.
Sample data, table1
CREATE TABLE table1 (id int identity (1,1), name varchar(60))
INSERT INTO table1
VALUES ('a1, a2, a9, a8')
Sample data, table2
CREATE TABLE table2 (id int identity (1,1), name varchar(60))
INSERT INTO table2
VALUES ('a1, a2, a9, a8')
The function:
CREATE FUNCTION f_split
(#id INT)
RETURNS #ab
TABLE (name VARCHAR(20),
ab1 VARCHAR(5)
)
AS
BEGIN
DECLARE #temp TABLE (rn INT, name VARCHAR(5))
INSERT INTO #temp(rn, name)
SELECT ROW_NUMBER() OVER(ORDER BY LTRIM(RTRIM(Split.a.value('.', 'NVARCHAR(MAX)'))) ASC) rn, LTRIM(RTRIM(Split.a.value('.', 'NVARCHAR(MAX)'))) Result
FROM
(
SELECT CAST('<X>'+REPLACE([name], ',', '</X><X>')+'</X>' AS XML) AS String
FROM table1 where id = #id
) AS A
CROSS APPLY String.nodes('/X') AS Split(a)
ORDER BY 1
INSERT INTO #ab
SELECT * FROM #temp
RETURN
END
This gives the result from table1.
SELECT * FROM F_SPLIT(1)
But I want the same function to work for table2 as well.
Any help is appreciated.
Use a partitioned view, which will allow you to specify the table name as a parameter in the where clause.
Start by creating a view that unions the two tables, plus an additional column to indicate which table the row comes from.
CREATE VIEW BothTables AS
SELECT 'Table1' TableName, * FROM Table1
UNION ALL
SELECT 'Table2' TableName, * FROM Table2
Then modify your function. When you pass the table name, use it to select a subset of rows from the view. So instead of
SELECT CAST('<X>'+REPLACE([name], ',', '</X><X>')+'</X>' AS XML) AS String
FROM table1
WHERE id = #id
Use
SELECT CAST('<X>'+REPLACE([name], ',', '</X><X>')+'</X>' AS XML) AS String
FROM BothTables
WHERE TableName = #TableName
AND id = #id
I need to insert multiple Table variables into one temp table.
One of the table variables is:
DECLARE ##TempTable_Number TABLE (Number bigint)
insert into ##TempTable_Number (Number) values ('000000000000');
insert into ##TempTable_Number (Number) values ('100000000000');
This works for inserting just one table variable
select * into ##GlobalTempTable_1 from ##TempTable_Number
I have a couple more table variables like
DECLARE ##TempTable_ID TABLE (Number int)
insert into ##TempTable_ID (ID) values ('1');
insert into ##TempTable_ID (ID) values ('12');
etc...
I tried this to insert data from multiple table variables into one TempTable:
Select * into ####GlobalTempTable_1 From ##TempTable_ID, ##TempTable_Number;
The query goes to a continuous loop...
EDIT:
One of the table variables is:
DECLARE ##TempTable_Number TABLE (Number bigint, ID int)
insert into ##gvTempTable (Number) values ('21212321332332');
insert into ##gvTempTable (Number) values ('100000000000');
insert into ##gvTempTable (ID) values ('1');
insert into ##gvTempTable (ID) values ('12');
select * into ##GlobalTempTable from ##gvTempTable;
select * from ##GlobalTempTable;
This returns a kind of a cartesian product
Use UNION ALL:
SELECT ID
INTO ##GlobalTempTable_1
FROM ##TempTable_ID
UNION ALL
SELECT Number
FROM ##TempTable_Number;
LiveDemo
Select * into ####GlobalTempTable_1 From ##TempTable_ID, ##TempTable_Number;
The query goes to a continuous loop...
It is probably not loop but very long query. Keep in mind that you do Cartesian product.
So your query is the same as:
SELECT *
INTO ##GlobalTempTable_1
FROM ##TempTable_ID
CROSS JOIN ##TempTable_Number;
And the result is NxM records where N is number of records in first table and M in the second.
Try like this,
DECLARE #TempTable TABLE (
ID INT
,Number BIGINT
)
INSERT INTO #TempTable (Number)
VALUES ('21212321332332');
INSERT INTO #TempTable (Number)
VALUES ('100000000000');
INSERT INTO #TempTable (ID)
VALUES ('1');
INSERT INTO #TempTable (ID)
VALUES ('12');
--select * into #GlobalTempTable from ##gvTempTable;
--select * from ##GlobalTempTable;
SELECT *
FROM #TempTable
SELECT A.ID
,B.Number
FROM (
SELECT ID
,ROW_NUMBER() OVER (
ORDER BY ID
) TempId
FROM #TempTable
WHERE id IS NOT NULL
) A
INNER JOIN (
SELECT number
,ROW_NUMBER() OVER (
ORDER BY id
) TempId
FROM #TempTable
WHERE number IS NOT NULL
) B ON A.TempId = B.TempId
The tables I have are;
TableA {TableA_OID, TableB_OID, SomeFields} //Source Table
TableB{TableB_OID, SomeFields} //Destination Table
I have to copy some data from source table to destination table, and on success i want to take the primary key identity field(TableB_OID) of destination table back to update (TableB_OID) field in the source table.
I think the following will work, but I'd play with it with some reasonable size data sets first, to be sure:
DECLARE #TA TABLE (ID INT IDENTITY(1,1), AID INT)
INSERT #TA(AID) SELECT TableA_OID FROM TABLEA -- ORDER BY data desc
DECLARE #TB TABLE (ID INT IDENTITY(1,1), BID INT)
INSERT TableB( data )
OUTPUT Inserted.TableB_OID INTO #TB(BID)
SELECT data
FROM #TA TA JOIN TableA ON TA.AID=TableA.TableA_OID ORDER BY TA.ID
SELECT * FROM #TA
SELECT * FROM #TB
UPDATE TableA
SET TableB_OID=TB.BID
FROM #TB TB
JOIN #TA TA ON TB.ID=TA.ID
JOIN TableA ON TA.AID=TableA.TableA_OID
SELECT * FROM TableA
SELECT * FROM TableB
First of all we're going to impose an order on the data we pull from table A, and use an identity column in a temporary table to record that order, linked to the original table A records. We'll then insert data into table B using that order, and record the resulting output into another temporary table. Again, we'll use an identity to record the sequence. We'll then use the identity values from the two temporary tables to link the tableA and tableB rows
I think you want to select the scope_identity()?
This will do a single row:
INSERT INTO TableB (
something
)
VALUES (
'Some Value'
)
DECLARE #Id int
SET #Id = scope_identity()
UPDATE TableA SET tableB_OID = #Id WHERE TableA_OID = TableAId
If you need to copy more than one row at once, something like the following will work:
DECLARE #data TABLE(ID int, data varchar(50))
INSERT TableB( data )
OUTPUT Inserted.TableB_OID, INSERTed.data INTO #data
SELECT data FROM TableA
UPDATE TableA
SET TableB_OID=D.ID
FROM #data D JOIN TableA ON D.DATA=TableA.data
It does make an assumption though, that there is a unique key in your "SomeField" (column "data") in my example, otherwise you can't relate the identity data back into tableA. If there is, then fine, otherwise, as Steph said, you'll need to add a TableA_OID field into TableB to be able to do the join to write back the data
I am trying to run a query given three tables.
DECLARE #TABLE1 TABLE (ID CHAR(2))
DECLARE #TABLE2 TABLE (ID CHAR(2))
DECLARE #TABLE3 TABLE (ID CHAR(2))
INSERT INTO #TABLE1 VALUES('1')
INSERT INTO #TABLE1 VALUES('2')
INSERT INTO #TABLE2 VALUES('1')
--NOTHING in TABLE3
I Need to get only the values that are present and ignore the null table. This doesn't work since TABLE3 has no values.
SELECT ID
FROM #TABLE1
INTERSECT
SELECT ID
FROM #TABLE2
INTERSECT
SELECT ID
FROM #TABLE3
**Result should be 1**
How do I ignore the any table if it's null but keep the other values?
Why not do a union of select distincts from each table, and then group that by ID and select count(*), and select only rows with count(*) equal to the maximum value of count(*) in the result?
It's a bit of a mess of subqueries at this point unfortunately but you should get the logic :)
Intersect is not going to work for you as you can't add conditions to it.
From what I understand you want to select all records where the ID appears in at least 2 of the tables. I am assuming that the ID is unique to each table.
The following works in MS SQL Server:
DECLARE #TABLE1 TABLE (ID CHAR(2))
DECLARE #TABLE2 TABLE (ID CHAR(2))
DECLARE #TABLE3 TABLE (ID CHAR(2))
INSERT INTO #TABLE1 VALUES('1')
INSERT INTO #TABLE1 VALUES('2')
INSERT INTO #TABLE2 VALUES('1')
--NOTHING in TABLE3
;WITH AllValues AS
(
SELECT ID
FROM #TABLE1
UNION ALL
SELECT ID
FROM #TABLE2
UNION ALL
SELECT ID
FROM #TABLE3
)
SELECT ID
FROM AllValues
GROUP BY ID
HAVING COUNT(*) > 1
Maybe... But the design of the system is extremely foreign; a real world example would help understand what you're trying to do.
Select count(*), ID FROM (
Select ID from #table1
UNION
Select ID from #table2
UNION
Select ID from #table3) Derived
Where RowNum =1
GROUP BY ID
ORder by count(*) DESC
Updated where clause was in wrong place
After having created a temporary table and declaring the data types like so;
CREATE TABLE #TempTable(
ID int,
Date datetime,
Name char(20))
How do I then insert the relevant data which is already held on a physical table within the database?
INSERT INTO #TempTable (ID, Date, Name)
SELECT id, date, name
FROM physical_table
To insert all data from all columns, just use this:
SELECT * INTO #TempTable
FROM OriginalTable
Don't forget to DROP the temporary table after you have finished with it and before you try creating it again:
DROP TABLE #TempTable
SELECT ID , Date , Name into #temp from [TableName]
My way of Insert in SQL Server. Also I usually check if a temporary table exists.
IF OBJECT_ID('tempdb..#MyTable') IS NOT NULL DROP Table #MyTable
SELECT b.Val as 'bVals'
INTO #MyTable
FROM OtherTable as b
SELECT *
INTO #TempTable
FROM table
I have provided two approaches to solve the same issue,
Solution 1: This approach includes 2 steps, first create a temporary table with
specified data type, next insert the value from the existing data
table.
CREATE TABLE #TempStudent(tempID int, tempName varchar(MAX) )
INSERT INTO #TempStudent(tempID, tempName) SELECT id, studName FROM students where id =1
SELECT * FROM #TempStudent
Solution 2: This approach is simple, where you can directly insert the values to
temporary table, where automatically the system take care of creating
the temp table with the same data type of original table.
SELECT id, studName INTO #TempStudent FROM students where id =1
SELECT * FROM #TempStudent
After you create the temp table you would just do a normal INSERT INTO () SELECT FROM
INSERT INTO #TempTable (id, Date, Name)
SELECT t.id, t.Date, t.Name
FROM yourTable t
The right query:
drop table #tmp_table
select new_acc_no, count(new_acc_no) as count1
into #tmp_table
from table
where unit_id = '0007'
group by unit_id, new_acc_no
having count(new_acc_no) > 1
insert into #temptable (col1, col2, col3)
select col1, col2, col3 from othertable
Note that this is considered poor practice:
insert into #temptable
select col1, col2, col3 from othertable
If the definition of the temp table were to change, the code could fail at runtime.
Basic operation of Temporary table is given below, modify and use as per your requirements,
-- CREATE A TEMP TABLE
CREATE TABLE #MyTempEmployeeTable(tempUserID varchar(MAX), tempUserName varchar(MAX) )
-- INSERT VALUE INTO A TEMP TABLE
INSERT INTO #MyTempEmployeeTable(tempUserID,tempUserName) SELECT userid,username FROM users where userid =21
-- QUERY A TEMP TABLE [This will work only in same session/Instance, not in other user session instance]
SELECT * FROM #MyTempEmployeeTable
-- DELETE VALUE IN TEMP TABLE
DELETE FROM #MyTempEmployeeTable
-- DROP A TEMP TABLE
DROP TABLE #MyTempEmployeeTable
INSERT INTO #TempTable(ID, Date, Name)
SELECT OtherID, OtherDate, OtherName FROM PhysicalTable
insert #temptable
select idfield, datefield, namefield from yourrealtable
All the above mentioned answers will almost fullfill the purpose. However, You need to drop the temp table after all the operation on it. You can follow-
INSERT INTO #TempTable (ID, Date, Name)
SELECT id, date, name
FROM physical_table;
IF OBJECT_ID('tempdb.dbo.#TempTable') IS NOT NULL
DROP TABLE #TempTable;
