I need to transform data from one schema into another in an MS Access database. This involves writing queries to select data from the old schema and then inserting the results of the queries into tables in the new schema. The below is an example of what I am trying to do. The SELECT component of the below works fine, but the INSERT component does not work. Can someone show me how to fix the below so that it effectively inserts the results of the SELECT statement into the destination table?
INSERT INTO CompaniesTable
(CompanyName)
VALUES
(
SELECT DISTINCT
IIF(a.FIRM_NAME IS NULL, b.SUBACCOUNT_COMPANY_NAME, a.FIRM_NAME) AS CompanyName
FROM
(SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS a
LEFT JOIN
(SELECT ContactID, FIRM_NAME, SUBACCOUNT_COMPANY_NAME FROM qrySummaryData) AS b
ON a.ContactID = b.ContactID
);
The definition of the target table (CompaniesTable) is:
CompanyID Autonumber
CompanyName Text
Description Text
WebSite Text
Email Text
TypeNumber Number
Maybe you have a typo but joining a table to itself you don't need the join, this should work fine. With an insert on a select statement you don't use the values keyword.
INSERT INTO CompaniesTable (CompanyName,Description,Website,Email,TypeNumber)
SELECT DISTINCT IIF(FIRM_NAME IS NULL, SUBACCOUNT_COMPANY_NAME, FIRM_NAME),
'','','',0
FROM qrySummaryData

I am fairly new to SQL, and I am hoping someone can help me with a problem I'm having. I haven't been able to find any answers helping me figure out this exact problem.
I have two tables in two SQL Server databases on two different servers that I want to compare using the column ItemID. I want to find records from Table1 that have an ItemID that does not exist in Table2 and insert those into a table variable. I have the following code:
--Create table variable to hold query results
DECLARE #ItemIDTable TABLE
(
[itemid][NVARCHAR](20) NULL
);
--Query data and insert results into table variable
INSERT INTO #ItemIDTable
([itemid])
SELECT a.[itemid]
FROM database1.dbo.table1 a
WHERE NOT EXISTS (SELECT 1
FROM [Database2].[dbo].[table2]
WHERE a.itemid = [Database2].[dbo].[table2].[itemid])
ORDER BY itemid
This works on a test server where the two databases are on the same server, but not in real life where they are on different servers. I tried the following using OPENQUERY, but I know I haven't got it quite right.
--Create table variable to hold query results
DECLARE #ItemIDTable TABLE
(
[ItemID][nvarchar](20) NULL
);
--Query data and insert results into table variable
INSERT INTO #ItemIDTable
([ItemID])
SELECT a.[ItemID]
FROM Database1.dbo.Table1 a
WHERE NOT EXISTS (SELECT 1
FROM OPENQUERY([Server2], SELECT * FROM [Database2].[dbo].[Table2]')
WHERE a.ItemID = [Database2].[dbo].[Table2].[ItemID])
ORDER BY ItemID
I'm pretty sure I need to do something in the WHERE clause, where I have the two databases on two servers, I'm just not quite sure how to structure it. Could anyone help?
You can't create an OPENQUERY that is correlated to an outer query. You could populate a temp table with the results of an OPENQUERY and do your WHERE NOT EXISTS against the temp table, or you might want to look into Synonyms.
Openquery works like this:
select *
from openquery
(LINKED_SERVER_NAME,
'select query goes here'
)
Note that the sql portion is single quoted. That means you might have to quote the quotes if necessary. For example:
select *
from openquery
(LINKED_SERVER_NAME,
'
select SomeTextField
from SomeTable
where SomeDateField = ''20141014''
'
)
I have a fully working stored procedure grabbing data from different tables using joins. I am currently using the below SELECT statement to select the data I require:
SELECT
ClientReference, ReferenceNumber, Text3,
ReceiptDate, [dbo].[Complaint].[Description],
ActionTaken, dbo.Category.Name, dbo.CategoryOption.FullName,
dbo.Complaint.AuditCreatedBy,
dbo.UserGroup.Name, dbo.Complaint.LoggedByUserId,
dbo.Complaint.LoggedByTime
FROM
dbo.Complaint
Now what I want to be able to do is insert this data into a temporary table. However, INSERT INTO does not work as I have two columns (resulting from my join) called Name.
How would I go about solving this?
Just alias one of the Name columns:
SELECT
ClientReference,
ReferenceNumber,
Text3,
ReceiptDate,
Complaint.Description,
ActionTaken,
Category.Name As CategoryName,
CategoryOption.FullName,
Complaint.AuditCreatedBy,
UserGroup.Name,
Complaint.LoggedByUserId,
Complaint.LoggedByTime
INTO #tempTable
FROM
dbo.Complaint
...
I'm doing a data conversion between systems and have prepared a select statement that identifies the necessary rows to pull from table1 and joins to table2 to display a pair of supporting columns. This select statement also places blank columns into the result in order to format the result for the upload to the destination system.
Beyond this query, I will also need to update some column values which I'd like to do in a separate statement operation in a new table. Therefore, I'm interested in running the above select statement as a subquery inside a SELECT INTO that will essentially plop the results into a staging table.
SELECT
dbo_tblPatCountryApplication.AppId, '',
dbo_tblPatCountryApplication.InvId,
'Add', dbo_tblpatinvention.disclosurestatus, ...
FROM
dbo_tblPatInvention
INNER JOIN
dbo_tblPatCountryApplication ON dbo_tblPatInvention.InvId = dbo_tblPatCountryApplication.InvId
ORDER BY
dbo_tblpatcountryapplication.invid;
I'd like to execute the above statement so that the results are dumped into a new table. Can anyone please advise how to embed the statement into a subquery that will play nicely with a SELECT INTO?
You can simply add an INTO clause to your existing query to create a new table filled with the results of the query:
SELECT ...
INTO MyNewStagingTable -- Creates a new table with the results of this query
FROM MyOtherTable
JOIN ...
However, you will have to make sure each column has a name, as in:
SELECT dbo_tblPatCountryApplication.AppId, -- Cool, already has a name
'' AS Column2, -- Given a name to create that new table with select...into
...
INTO MyNewStagingTable
FROM dbo_tblPatInvention INNER JOIN ...
Also, you might like to use aliases for your tables, too, to make code a little more readable;
SELECT a.AppId,
'' AS Column2,
...
INTO MyNewStagingTable
FROM dbo_tblPatInvention AS i
INNER JOIN dbo_tblPatCountryApplication AS a ON i.InvId = a.InvId
ORDER BY a.InvId
One last note is that it looks odd to have named your tables dbo_tblXXX as dbo is normally the schema name and is separated from the table name with dot notation, e.g. dbo.tblXXX. I'm assuming that you already have a fully working select query before adding the into clause. Some also consider using Hungarian notation in your database (tblName) to be a type of anti-pattern to avoid.
If the staging table doesn't exist and you want to create it on insert then try the following:
SELECT dbo_tblPatCountryApplication.AppId,'', dbo_tblPatCountryApplication.InvId,
'Add', dbo_tblpatinvention.disclosurestatus .......
INTO StagingTable
FROM dbo_tblPatInvention
INNER JOIN dbo_tblPatCountryApplication
ON dbo_tblPatInvention.InvId = dbo_tblPatCountryApplication.InvId;
If you want to insert them in a specific order then use try using a sub-query in the from clause:
SELECT *
INTO StagingTable
FROM
(
SELECT dbo_tblPatCountryApplication.AppId, '', dbo_tblPatCountryApplication.InvId,
'Add', dbo_tblpatinvention.disclosurestatus .......
FROM dbo_tblPatInvention
INNER JOIN dbo_tblPatCountryApplication ON
dbo_tblPatInvention.InvId = dbo_tblPatCountryApplication.InvId
order by dbo_tblpatcountryapplication.invid
) a;
Try
INSERT INTO stagingtable (AppId, ...)
SELECT ... --your select goes here
This is a specific problem .
I have an excel sheet containing data. Similar data is present in a relational database table. Some rows may be absent or some additional rows may be present. The goal is to verify the data in the excel sheet with the data in the table.
I have the following query
Select e_no, start_dt,end_dt
From MY_TABLE
Where e_no In
(20231, 457)
In this case, e_no 457 is not present in the database (and hence not returned). But I want my query to return a row even if it not present (457 , null , null). How do I do that ?
For Sql-Server: Use a temporary table or table type variable and left join MY_TABLE with it
Sql-Server fiddle demo
Declare #Temp Table (e_no int)
Insert into #Temp
Values (20231), (457)
Select t.e_no, m.start_dt, m.end_dt
From #temp t left join MY_TABLE m on t.e_no = m.e_no
If your passing values are a csv list, then use a split function to get the values inserted to #Temp.
Why not simply populate a temporary table in the database from your spreadsheet and join against that? Any other solution is probably going to be both more work and more difficult to maintain.
You can also do it this way with a UNION
Select
e_no, start_dt ,end_dt
From MY_TABLE
Where e_no In (20231, 457)
UNION
Select 457, null, null
I am trying to update one table from another, im able to update fine as long as the customer record exists, but there are some entries that dont.
To solve this i've tried running the following insert
SELECT *
INTO SalBudgetCust
FROM SalBudgetCust_temp
WHERE NOT EXISTS (
SELECT Customer
FROM SalBudgetCust
WHERE Customer = SalBudgetCust_temp.Customer
)
but im prompted with
There is already an object named 'SalBudgetCust' in the database.
Im stuck at this point... could anyone offer a little guideance?
SELECT INTO implicitly creates the table you name. You should instead use INSERT INTO ... SELECT * FROM ..., so that the existing table is used.
It should be INSERT INTO instead of SELECT * INTO ... like
INSERT INTO SalBudgetCust SELECT * FROM SalBudgetCust_temp
WHERE NOT EXISTS
(
SELECT Customer FROM SalBudgetCust WHERE Customer = SalBudgetCust_temp.Customer
)
The general syntax to insert data of one table into another is :
INSERT INTO new_table
SELECT * FROM old_table
WHERE some_condition;
Where, new_table is the table where you want to insert data, old_table is table from where you are fetching data and some_condition is the expression / condition based upon which you want to fetch data from old table.
You may use other clauses like order by, group by, and even sub queries after where clause.
