I have an SQL view created by joining columns of two separate tables.
I need to know how to insert a record into this view.
Here's the code I tried,
create view P_Order
as
select Product.Pname, Product.Pdesc, Product.Pprice, Order1.Onumber, Order1.Oqty
from Product
join Order1
on Order1.Procode=Product.Pcode;
select * from P_Order;
insert into P_Order (Pname, Pdesc, Pprice, Onumber, Oqty) values('Toshiba','Television',48000.00,10023,25);
It generated an error saying,
View or function 'P_Order' is not updatable because the modification affects multiple base tables.
How can I fix this?
Inserting Records into a VIEW with two table in Join Condition in not advisable it leads to multiple changes in the both tables.
So Instead of inserting them into the View, you can insert the records into separate tables.
This is an issue I have been working on for a while, I have three tables, all of which share 3 of the same columns but there are rows that are unique to each row. I would like to combine all of the tables without duplicating rows. I have a working solution but I feel like it might not be the most efficient. I tried using joins but found that without a parent table, I wasn't getting the expected number of results. My solution which does yield the correct number of results(I've cut some columns for simplicity):
--Create table
CREATE TABLE #Temp
(
ID,
Date
)
-- Insert rows that are only in db1
INSERT INTO #Temp
SELECT
ID,
Date
FROM test.dbo.db1
-- Do not include rows shared by db1 and db2
EXCEPT
(
SELECT
ID,
Date
FROM test.dbo.db2
INTERSECT
SELECT
ID,
Date
FROM test.dbo.db1
)
EXCEPT
-- And not in db1 and db3
(
SELECT
ID,
Date
FROM test.dbo.db1
INTERSECT
SELECT
ID,
Date
FROM test.dbo.db3
)
EXCEPT
-- And not in db1, db2 and db3
** Code where I intersect all 3 tables
I repeat the above steps for all three tables and then add the intersections for each combined ID/Date(db1+d2+db3, db1+db2, etc...)
Does anyone know of a way to do this that is more direct and to the point? I have tried doing a full join of all of them but without a parent table with all of the ID's, I found the ID's that only appear in the other two tables don't show up.
SELECT
ID,
Date
FROM test.dbo.db1
UNION
SELECT
ID,
Date
FROM test.dbo.db2
UNION
SELECT
ID,
Date
FROM test.dbo.db3
The UNION takes care of removing duplicates.
I am creating a view for a table and joining multiple tables for additional columns, getting exact output for some join tables which has only two columns(ID, Name) in it. But i am getting 'Ambiguous column error' for a column which i am using one join table which has more than 10 columns in it.
I know why I am getting this error but i need help to call the EventName from EventInfo join table. Also is it possible to give different column names in the view.
Below are the select statement and the join table that I am getting error.
Thanks in advance for your suggestions.
SELECT
Event_ID, EventName
FROM
[dbo].[tbl_ValueTool_Event_ResultantDataEntryData] Res_event
JOIN
[GRID_ProjectServer_Applications].[dbo].[tbl_ValueTool_EventInformation] EVT ON Res_event.[Event_ID] = EVT.[Event_ID]
Below is the join table from which I want to call the column names corresponding to the Id's
You can use alias for the column names if needed.
SELECT EVT.Event_ID, EVT.EventName
FROM [dbo].[tbl_ValueTool_Event_ResultantDataEntryData] Res_event
JOIN [GRID_ProjectServer_Applications].[dbo].[tbl_ValueTool_EventInformation] EVT
ON Res_event.[Event_ID] = EVT.[Event_ID]
I have two tables namely :- TDM & AccountMaster. Both are having three equal columns and I have to create a table retrieving all the rows from TDM-table joining the three columns,i.e. FD_BRANCH,FD_CUSTCODE & PRODUCTID.
while creating table through select into clause I get an error
Column names in each table must be unique. Column name 'FD_BRANCH' in table 'acty' is specified more than once.
Please find the following query from which I want to create a table which as per my requirement :-
SELECT * FROM (SELECT FD_BRANCH,FD_CUSTCODE,PRODUCTID FROM TDM
GROUP BY FD_BRANCH,FD_CUSTCODE,PRODUCTID) A full OUTER JOIN AccountMaster B
ON( A.FD_BRANCH=B.FD_BRANCH AND A.FD_CUSTCODE=B.FD_CUSTCODE AND
A.PRODUCTID=B.PRODUCTID)
Change your select to get only the fields you need from one of the 2 tables.
Select A.*
FROM (
or
Select B.FD_BRANCH,
B.FD_CUSTCODE,
B.PRODUCTID
FROM (
FULL OUTER JOIN combines the 2 sets of columns from both queries so you end up with at least 6 columns. Even though they're from different tables or aliases the columns names are the same.
I need to search across multiple columns from two tables in my database using Full-Text Search. The two tables in question have the relevant columns full-text indexed.
The reason I'm opting for Full-text search:
1. To be able to search accented words easily (cafè)
2. To be able to rank according to word proximity, etc.
3. "Did you mean XXX?" functionality
Here is a dummy table structure, to illustrate the challenge:
Table Book
BookID
Name (Full-text indexed)
Notes (Full-text indexed)
Table Shelf
ShelfID
BookID
Table ShelfAuthor
AuthorID
ShelfID
Table Author
AuthorID
Name (Full-text indexed)
I need to search across Book Name, Book Notes and Author Name.
I know of two ways to accomplish this:
Using a Full-text Indexed View: This would have been my preferred method, but I can't do this because for a view to be full-text indexed, it needs to be schemabound, not have any outer joins, have a unique index. The view I will need to get my data does not satisfy these constraints (it contains many other joined tables I need to get data from).
Using joins in a stored procedure: The problem with this approach is that I need to have the results sorted by rank. If I am making multiple joins across the tables, SQL Server won't search across multiple fields by default. I can combine two individual CONTAINS queries on the two linked tables, but I don't know of a way to extract the combined rank from the two search queries. For example, if I search for 'Arthur', the results of both the Book query and the Author query should be taken into account and weighted accordingly.
Using FREETEXTTABLE, you just need to design some algorithm to calculate the merged rank on each joined table result. The example below skews the result towards hits from the book table.
SELECT b.Name, a.Name, bkt.[Rank] + akt.[Rank]/2 AS [Rank]
FROM Book b
INNER JOIN Author a ON b.AuthorID = a.AuthorID
INNER JOIN FREETEXTTABLE(Book, Name, #criteria) bkt ON b.ContentID = bkt.[Key]
LEFT JOIN FREETEXTTABLE(Author, Name, #criteria) akt ON a.AuthorID = akt.[Key]
ORDER BY [Rank] DESC
Note that I simplified your schema for this example.
I had the same problem as you but it actually involved 10 tables (a Users table and several others for information)
I did my first query using FREETEXT in the WHERE clause for each table but the query was taking far too long.
I then saw several replies about using FREETEXTTABLE instead and checking for not nulls values in the key column for each table, but that took also to long to execute.
I fixed it by using a combination of FREETEXTTABLE and UNION selects:
SELECT Users.* FROM Users INNER JOIN
(SELECT Users.UserId FROM Users INNER JOIN FREETEXTTABLE(Users, (column1, column2), #variableWithSearchTerm) UsersFT ON Users.UserId = UsersFT.key
UNION
SELECT Table1.UserId FROM Table1 INNER JOIN FREETEXTTABLE(Table1, TextColumn, #variableWithSearchTerm) Table1FT ON Table1.UserId = Table1FT.key
UNION
SELECT Table2.UserId FROM Table2 INNER JOIN FREETEXTTABLE(Table2, TextColumn, #variableWithSearchTerm) Table2FT ON Table2.UserId = Table2FT.key
... --same for all tables
) fts ON Users.UserId = fts.UserId
This proved to be incredibly much faster.
I hope it helps.
I don't think the accepted answer will solve the problem. If you try to find all the books from a certain author and, therefore, use the author's name (or part of it) as the search criteria, the only books returned by the query will be those which have the search criteria in its own name.
The only way I see around this problem is to replicate the Author's columns that you wish to search by in the Book table and index those columns (or column since it would probably be smart to store the author's relevant information in an XML column in the Book table).
FWIW, in a similar situation our DBA created DML triggers to maintain a dedicated full-text search table. It was not possible to use a materialized view because of its many restrictions.
I would use a stored procedure. The full text method or whatever returns a rank which you can sort by. I am not sure how they will be weighted against eachother, but I'm sure you could tinker for awhile and figure it out. For example:
Select SearchResults.key, SearchResults.rank From FREETEXTTABLE(myColumn, *, #searchString) as SearchResults Order By SearchResults.rank Desc
This answer is well overdue, but one way to do this if you cannot modify primary tables is to create a new table with the search parameters added to one column.
Then create a full text index on that column and query that column.
Example
SELECT
FT_TBL.[EANHotelID] AS HotelID,
ISNULL(FT_TBL.[Name],'-') AS HotelName,
ISNULL(FT_TBL.[Address1],'-') AS HotelAddress,
ISNULL(FT_TBL.[City],'-') AS HotelCity,
ISNULL(FT_TBL.[StateProvince],'-') AS HotelCountyState,
ISNULL(FT_TBL.[PostalCode],'-') AS HotelPostZipCode,
ISNULL(FT_TBL.[Latitude],0.00) AS HotelLatitude,
ISNULL(FT_TBL.[Longitude],0.00) AS HotelLongitude,
ISNULL(FT_TBL.[CheckInTime],'-') AS HotelCheckinTime,
ISNULL(FT_TBL.[CheckOutTime],'-') AS HotelCheckOutTime,
ISNULL(b.[CountryName],'-') AS HotelCountry,
ISNULL(c.PropertyDescription,'-') AS HotelDescription,
KEY_TBL.RANK
FROM [EAN].[dbo].[tblactivepropertylist] AS FT_TBL INNER JOIN
CONTAINSTABLE ([EAN].[dbo].[tblEanFullTextSearch], FullTextSearchColumn, #s)
AS KEY_TBL
ON FT_TBL.EANHotelID = KEY_TBL.[KEY]
INNER JOIN [EAN].[dbo].[tblCountrylist] b
ON FT_TBL.Country = b.CountryCode
INNER JOIN [EAN].[dbo].[tblPropertyDescriptionList] c
ON FT_TBL.[EANHotelID] = c.EANHotelID
In the code above [EAN].[dbo].[tblEanFullTextSearch], FullTextSearchColumn is the new table and column with the fields added, you can now do a query on the new table with joins to the table you want to display the data from.
Hope this helps
