Actually both tables are the same, and I just need to merge data. Problem is that one column is defined with XML shema, which is same in both tables, and for my query I am getting this error from sql server studio:
"Implicit conversion between XML types constrained by different XML schema collections is not allowed. Use the CONVERT function to run this query."
Help me writedown this query.
I have something like this:
INSERT INTO table1
SELECT * FROM table2
WHERE id NOT IN (select id from table1);
Without more info on your table structure and the xml schemas I'm not sure how much assistance I can be. That said there's an article that discusses this exact problem here
http://sqlblogcasts.com/blogs/martinbell/archive/2010/11/08/Using-XML-Schemas.aspx
And his example of using the convert statement to overcome exactly this problem is as follows.
INSERT INTO [dbo].[Test_ProductModel_Content]( [CatalogDescription] )
SELECT CONVERT(XML, [CatalogDescription] )
FROM AdventureWorks2008.Production.ProductModel
WHERE [CatalogDescription] IS NOT NULL ;
GO
Hope that helps, if not post more information and I'm sure someone can help you out.

I have been running into trouble executing SQL code in VBA Access when I refer to certain Table names.
For example,
INSERT INTO TempTable (ClientName) SELECT DISTINCT 1_1_xlsx.ClientName FROM 1_1_xlsx'<--does not work
The code works fine when I changed the Table name from 1_1_xlsx to Stuff.
INSERT INTO TempTable (ClientName) SELECT DISTINCT Stuff.ClientName FROM Stuff '<--works
I have no idea why the first query results in a syntax error and the second code is runs fine even when they refer to the same thing. I suspect it should be the naming conventions but I could not find any concrete answers.
Also, are there any ways that I could use 1_1_xlsx as my table name? Or am I just writing my query wrong?
try this:
INSERT INTO TempTable (ClientName) SELECT DISTINCT [1_1_xlsx].ClientName FROM [1_1_xlsx]
In many SQL based databases you can't have a table name or field name that starts with a number.
I suspect this is the underlying reason for your problem. Although Access will allow it, I have seen it cause problems in the past.
The problem is the number at the beginning of the table name. That is bad -- because it confuses the parser.
This is a bad table name, but SQL allows you to define table aliases. And, in this case, you don't even need to repeat the table name. So, here are two simple solutions:
INSERT INTO TempTable (ClientName)
SELECT DISTINCT ClientName
FROM 1_1_xlsx;
Or:
INSERT INTO TempTable (ClientName)
SELECT DISTINCT t.ClientName
FROM 1_1_xlsx as t
There is no reason to use the complete table name as an alias. That just makes the query harder to write and to read.
first off, noob alert! :))
I need to construct a query that runs on many tables. The tables vary on name just on the last digits as per client code. The thing is, the values that change aren't sequential so looping as in i=1,2,3,... does not work. A possible solution would be to have those values on a given field on an other table.
Here is the code for the first two clients 015 and 061. The leading zero(s) must are essential.
SELECT LnMov2017015.CConta, RsMov2017015.DR, RsMov2017015.NInt, "015" AS CodCli
FROM LnMov2017015 INNER JOIN RsMov2017015 ON LnMov2017015.NReg = RsMov2017015.NReg
WHERE (((LnMov2017015.CConta)="6" And (LnMov2017015.CConta)="7") AND ((RsMov2017015.DR)=9999))
UNION SELECT LnMov2017061.CConta, RsMov2017061.DR, RsMov2017061.NInt, "061" AS CodCli
FROM LnMov2017061 INNER JOIN RsMov2017061 ON LnMov2017061.NReg = RsMov2017061.NReg
WHERE (((LnMov2017061.CConta)="6" And (LnMov2017061.CConta)="7") AND ((RsMov2017061.DR)=9999))
...
So for the first SELECT the table Name is LnMov2017015, the ending 015 being the value, the client code, that changes from table to table e.g. in the second SELECT the table name is LnMov2017061 (061) being what distinguishes the table.
For each client code there are two tables e.g. LnMov2017015 and RsMov2017015 (LnMov2017061 and RsMov2017061 for the second set client shown).
Is there a way that I can build the SQL, based upon the example SQL above?
Does anyone have an idea for a solution? :)
Apparently it is possible to build a query object to read data in another db without establishing table link. Just tested and to my surprise it works. Example:
SELECT * FROM [SoilsAgg] IN "C:\Users\Owner\June\DOT\Lab\Editing\ConstructionData.accdb";
I was already using this structure in VBA to execute DELETE and UPDATE action statements.
Solution found :)
Thank you all for your input.
Instead of linking 100 tables (password protected), I'll access them with SLQ
FROM Table2 IN '' ';database=C:\db\db2.mdb;PWD=mypwd'
And merge them all with a query, before any other thing!
I'm looking for an efficient way of how to convert rows to columns in SQL Server. I tried in Toad for Oracle, but now I want it in SQL Server.
This is my example:
CID SENTENCE
1 Hello; Hi;
2 Why; What;
The result should be like
CID SENTENCE
1 Hello
1 Hi
2 Why
2 What
Would you please help me with it?
I would advise you to rethink your database design. It's almost never a good idea to store data in a delimited string in any relational database.
If it's impossible to change your database design, you need to use some UDF to split strings.
There are many different approaches to split strings in sql server, read this article on the differences between the common ways.
You can probably change your chosen split string function to take the cid as well as the sentence as a variable and have it return the data exactly as your desired output for each row in your table.
Then all you have to do is a select from your table with an inner join with the udf on the cid.
try
declare #var table (CID int, SENTENCE varchar(50))
insert into #var(CID,SENTENCE) values
(1,'Hello; Hi;'),
(2,'Why; What;')
select cid,t.c.value('.','varchar(50)') as val
from (select cid,x=cast('<t>'+ replace(stuff(sentence,len(sentence),1,''),';','</t><t>')+'</t>' as xml)
from #var) a cross apply x.nodes('/t') t(c)
I'm trying to create a stored procedure in sql 2008 to select the id values from some xml like this.
DECLARE #idPolygonXML XML
SET #idPolygonXML =
'<polygons>
<id>35</id>
<id>36</id>
<id>37</id>
<id>38</id>
<id>39</id>
<id>40</id>
</polygons>'
I can get the id for a specific index but I need all of them and I keep getting 'value() requires a singleton'.
Does anyone know how I can get all these values without changing the xml?
Take a look at this: http://msdn.microsoft.com/en-us/library/ms188282.aspx
This isn't tested, but your query would look something like this
SELECT T2.ID.query('.')
CROSS APPLY #idPolygonXML.nodes('/polygons/id') as T2(ID)
I created a table with this schema using sqlite3:
CREATE TABLE monitored_files (file_id INTEGER PRIMARY KEY,file_name VARCHAR(32767),original_relative_dir_path VARCHAR(32767),backupped_relative_dir_path VARCHAR(32767),directory_id INTEGER);
now, I would like to get all the records where original_relative_dir_path is exactly equal to '.', without 's. What I did is this:
select * from monitored_files where original_relative_dir_path='.';
The result is no records even if in the table I have just this record:
1|'P9040479.JPG'|'.'|'.'|1
I read on the web and I see no mistakes in my syntax... I also tried using LIKE '.', but still no results. I'm not an expert of SQL so maybe you can see something wrong?
Thanks!
I see no problem with the statement.
I created the table that you described.
Did an INSERT with the same values that you provided.
And did the query, and also queried without a where clause.
No problems encountered, so I suspect that when you execute your selection, you may not be connected to the correct database.
