I have a query in MS ACCESS, I ran it in MS ACCESS:
SELECT * FROM table1
INNER JOIN table2 ON table1.f1=table2.f1 WHERE table1.f2=table2.f2
It works fine. However, I need to save the results into another table. So, I changed it to:
SELECT * Into a1
FROM table1 INNER JOIN table2 ON table1.f1=table2.f1 WHERE table1.f2=table2.f2
It does not work. I receive this error: "Cannot Open database. It may not be a database that your application recognizes, or the file may be corrupt."
Does anybody know how I can save the results in a database or txt file?
Thank you very much.
You can use the insert into command, see: http://msdn.microsoft.com/en-us/library/bb208861(office.12).aspx
Also appears that the database is in read only mode.
Is the database read-only?
Some things to check:
Is the DB file's read-only attribute set?
Did you use "Open Read Only" to open the DB?
Are you out of disk space?
Is there enough disk space to create the new table?
You can easily output the results as a .txt file or a .csv file (that you can view in Excel). To export a .txt file:
DoCmd.TransferText acExportDelim, , "myQuery", "C:\myQuery.txt", True
You can research TransferText in help to see the options for a .csv file.
This should work easily.
try create a new table with the values mentioned at your select.
step 1:
CREATE TABLE table_shadi
(
column_name1 data_type,
column_name2 data_type,
column_name3 data_type,
....
)
make sure you defined the same datatypes and number of fields as expected from you query
step 2:
Insert into table_shadi(column_name1,column_name2,column_name3)
SELECT column_name1,column_name2,column_name3
FROM table1
INNER JOIN table2
ON table1.f1=table2.f1
WHERE table1.f2=table2.f2
Hope it helps.

I'm pretty new to SQL and need some help configuring a command. The details of my database structure can be found in this thread:
How to copy new data but skip old data from 2 tables in MySQL
The general problem is that I'm merging a new (temporary) database with an old one. I want to keep all the data in the old but copy over any new data from the new. If there is a duplicate, the old should be favored/kept.
My current command is:
INSERT INTO BAT_players
SELECT *
FROM bat2.bat_players
WHERE NOT EXISTS (SELECT 1 FROM BAT_players WHERE BAT_players(UUID) = bat2.bat_players(UUID));
When I run this, I get
Function bat2.bat_players undefined or Function bat.BAT_players undefined
I do not know how to proceed and would appreciate the help.
Columns are accessed using . not parens:
INSERT INTO BAT_players
SELECT *
FROM bat2.bat_players bp2
WHERE NOT EXISTS (SELECT 1
FROM BAT_players bp
WHERE bp.UUID = bp2.UUID
);
Note that the columns have to correspond by position, because you are not explicitly listing them. As a general rule, you want to list all all the columns in an insert:
INSERT INTO BAT_players ( . . . )
SELECT . . .
. . .
I am no familiar with the idea of MySQL,
I worked with SQL Server to be honest but if all the infrastructure are the same and I say IF, then there is a trick to these kinds of transactions between databases and that's simply the phrase dbo.
Like below:
using BAT
Insert into bat_players
SELECT * FROM bat2.dbo.bat_players
and also the rest of your conditions
or
instead of using the phrase using bat you can simply add the dbo to:
Insert into bat.dbo.bat_players
and again the rest of your condition,
just remember to use the dbo before each [table name].
HUGE UPDATE
if you want to access the fields (columns) you have to use . as #Gordon Linoff explained above. For example:
...
Where bat2.dbo.bat_players.UUID = --the condition--
I have to work on a linked server. My goal: Update an entire table in mysql server(version:8.0.21) via OPENQUERY in SQL Server(version 13.0.1742.0). I tried this but it generates an error Row cannot be located for updating. Some values may have been changed since it was last read and this one The rowset was using optimistic concurrency and the value of a column has been changed after the containing row was last fetched or resynchronized.
update linkedTable
set
linkedTable.id_parent=unlinkedTable.IdCat1,
linkedTable.code=unlinkedTable.CodeFamilleFAT,
linkedTable.niveau=unlinkedTable.NiveauCategorieFAT,
linkedTable.langue=unlinkedTable.CodeLangueFAT,
linkedTable.nom=unlinkedTable.LibelleCommercialFAT,
linkedTable.descriptionA=unlinkedTable.DescriptifCom1FAT,
linkedTable.vignette=null,
linkedTable.id_categorie=unlinkedTable.id
from openquery(NAMELINKEDSERVER, 'select id_categorie, id_parent, code, niveau, langue, nom, description as descriptionA, vignette from DatabaseMySQL.Table') as linkedTable
inner join DatabaseSQLserver.dbo.Table as unlinkedTable on unlinkedTable.Id = linkedTable.id_categorie
Then I tried this:
update linkedTable
set
linkedTable.id_parent=unlinkedTable.IdCat1,
linkedTable.code=unlinkedTable.CodeFamilleFAT,
linkedTable.niveau=unlinkedTable.NiveauCategorieFAT,
linkedTable.langue=unlinkedTable.CodeLangueFAT,
linkedTable.nom=unlinkedTable.LibelleCommercialFAT,
linkedTable.descriptionA=unlinkedTable.DescriptifCom1FAT,
linkedTable.vignette=null,
linkedTable.id_categorie=unlinkedTable.id
from openquery(NAMELINKEDSERVER, 'select id_categorie, id_parent, code, niveau, langue, nom, description as descriptionA, vignette from DatabaseMySQL.Table') as linkedTable
inner join DatabaseSQLserver.dbo.Table as unlinkedTable on unlinkedTable.Id = linkedTable.id_categorie
where linkedTable.id_categorie = 1
This work but only one row is updated. So I wrote a stored procedure to update each line but it took too much time.
Can someone explain why my first query didn't work (question1) and how I can reduce the time of my stored procedure (question2)?
I use while loop (count the number of id and update each id).
Thank you in advance.
Kind Regards.
I resolve the problem by checking some option on ODBC Driver in MySQL and reading some forum. I check this box.
enter image description here
This option allows to avoid the errors quoted previously. With this option, i can update multiple values without error on join or other request. Thank you Solarflare and "Another guy" (i lost the name) for correcting me (EDIT A POST). Have nice day both.
Before anyone says this is a duplicate, I havent found this case anywhere.
I make my query (a joined query with 4 tables) and then hit EXPORT, but it exports just the table and not the query with the combined info and not just the fields I asked for but ALL the fields of the first table in the query. So basically, the query is ignored at the export stage.
I have loooked into "INTO OUTFILE" however, I do not have the right access to access the file after it is created.
I wonder if "INTO OUTFILE" can save files elsewhere? (remotely, I mean)
I wonder if the amount of results (6200( is straining the server?
My code :
SELECT pname, concat(afname, ' ', alname) as artistname, pubname, pwide, phigh, concat(pubcode,'-',psku) as fullsku, catname, concat('/prints/', pubcode,'-',psku, '.jpg') as imagesource, ptext FROM (prints LEFT JOIN publishers ON (publishers.pubid=prints.ppub) LEFT JOIN artists ON (artistid=partist)) LEFT JOIN cats ON (pcat = catid) WHERE psku <> '' AND phigh > 0 ORDER BY pubname,ltrim(alname),ltrim(afname) LIMIT 6200
I have the same problem, when hitting the "export" button at the bottom of my query results, phpmyadmin exports one of the tables, not the query results. I can't figure why. My workaround is to create a new table, adding
CREATE TABLE xxxx AS
before my select query, and then export this new table.
Since I haven't heard anything, I will post my very lame workaround but at least I got what I wanted.
I did a copy/paste into BBEdit and then tidied up the data with a series of find/replaces.
Not ideal and not the quickest solution, but it worked where nothing else would.
I have a lot of tables in my data base all with same structure. I want to select from all tables without having to list them all like so:
SELECT name FROM table1,table2,table3,table4
And I tried but this doesn't work:
SELECT name FROM *
Is there a way to select all tables in a database without listing each table in the query?
i am working on a online file browser, each directory has its own table
It is very unuseful due to one reason: when you have about 200 files (this situation is real, yeah?) you have about 200 tables. And if there are about thousand files in each directory.. etc. In some time you will either have slow processing while selecting from your database either have to buy more server resources.
I think you should change your database structure: just begin from adding parent_folder_id column to your table, after this you can put all your rows (files and directories -- because directory is a file too -- here you can add type column to determine this) into the one table.
As far as I know there are no such wildcards to select from *all tables. I would recommend writing a view and then call that view instead (it will save you writing out the names every time) – VoodooChild
That means you should not have a lot of tables with same structure at all.
But just one table with a field to distinguish different kinds of data, whatever it is.
Then select all would be no problem.
I found a solution, but I would still like to know if there is a simpler way or a better solution.
But here's what I came up with:
$tables = mysql_query("show tables");
$string = '';
while ($table_data = mysql_fetch_row($tables)){
$string.=$table_data[0].',';
}
$ALL_TABLES = substr($string,0,strlen($string)-1);
$sql="SELECT name FROM $ALL_TABLES ";
Sounds like you want to UNION together each table, so you get the results as if they were one big table. You'll need to write out the query in full like
SELECT * FROM table1 UNION SELECT * FROM table2 UNION ... SELECT * FROM tableN
Copy & paste may be your friend here.
I'm curious as to why you have lots of different tables with the same structure?
You can generate SELECT by cursor like this code
and find all result step by step in sql server:
--Author: Ah.Ghasemi
Declare #Select sysname;
DECLARE A CURSOR
FOR Select 'select ' + '*' + ' from ' + name
from sys.tables
--Where name like 'tbl%'
Order by name
OPEN A
FETCH NEXT FROM A INTO #Select
While (##FETCH_STATUS <>-1)
Begin
exec sp_executesql #Select
FETCH NEXT FROM A INTO #Select;
End
close A
Deallocate A
Please let us know if the problem is not resolved.
I hope you for the best
I need to use text files as data source in SSRS. I tried accessing this with ‘OLEDB provider for Microsoft directory services’ connection. But I could not. The query is given below.
Also let me know how to query the data
I know this thread is old, but as it came up in my search results this may help other people.
There are two 'sort of' workarounds for this. See the following:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=130650
So basically you should use OLEDB as the data source, then in the connection string type:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=xxxx;Extended Properties="text;HDR=No;FMT=Delimited"
Then make sure your file is saved in .txt format, with comma delimiters. Where I've put xxxx you need to put the FOLDER directory - so C:\Temp - don't go down to the individual file level, just the folder it's in.
In the query you write for the dataset, you specify the file name as though it were a table - essentially your folder is your database, and the files in it are tables.
Thanks
I have had great success creating linked servers in SQL to link to disparate text files for creating SSRS reports. Below is sample SQL to link to your txt files:
EXEC master.dbo.sp_addlinkedserver #server = N'', #srvproduct=N'', #provider=N'Microsoft.Jet.OLEDB.4.0', #datasrc=N'', #provstr=N'text'
EXEC master.dbo.sp_addlinkedsrvlogin #rmtsrvname=N'YourLinkedServerName',#useself=N'False',#locallogin=NULL,#rmtuser=NULL,#rmtpassword=NULL
I simply used BULK INSERT command to load the flat file into a temporary table in SSRS, like this:
CREATE TABLE #FlatFile
(
Field1 int,
Field2 varchar(10),
Field3 varchar(15),
Field4 varchar(20),
Field5 varchar(50)
)
BEGIN TRY
BULK INSERT #FlatFile
FROM 'C:\My_Path\My_File.txt'
WITH
(
FIELDTERMINATOR ='\t', -- TAB delimited
ROWTERMINATOR ='\n', -- or '0x0a' (whatever works)
FIRSTROW = 2, -- has 1 header row
ERRORFILE = 'C:\My_Path\My_Error_File.txt',
TABLOCK
);
END TRY
BEGIN CATCH
-- do nothing (prevent the query from aborting on errors...)
END CATCH
SELECT * FROM #FlatFile
I don't think you can
Data Sources Supported by Reporting Services. In the table, your only chance would be "Generic ODBC data source", however a text file is not ODBC compliant AFAIK. No types, no structure etc.
Why not just display the text files? It seems a bit strange to query text files to bloat them into formatted HTML...
I'm not of the mind that you can, but a workaround for this, if your text files are CSVs or the like, is to create an SSIS package which brings that data into a table in SQL Server, which you can then query like there's no tomorrow. SSIS does Flat File Sources with ease.
You can even automate this by right clicking the database in SSMS, doing Tasks->Import Data. Walk through the wizard, and you can then save off the package at the end.
