I normally work with PHP/MySQL. A client wants to send variables from a .bat file - to a remote MySQL - where I will then manipulate them for display etc. I do not know how to connect and send these variables from a bat file in Windows.
I have small .bat file on windows, that simply writes a few variables to a text file.
#echo off
#echo Data: > test.txt
#echo VAR_1=777 >> test.txt
#echo VAR_2=245.67 >> test.txt
The result of the .bat file is a text file test.txt created with various details in it.
I would like the .bat file commands to also:
1) connect to a remote MySQL database
connect -> '8580922.hostedresource.com'
2) save to a basic table on a remote MySQL database:
INSERT INTO `My_Database`.`My_Table` (
`VAR_1` ,
`VAR_2` ,
)
VALUES (
'777',
'245.67'
);
Is this possible?
Is so - how?
I don't have MySQL Installed and I'm not familiar with it but here is a crack at something to try, based on info from the linked page.
REM This needs to be set to the right path
set bin=C:\Program Files\MySQL\MySQL Server 5.6\bin
REM set the host name and db
SET DBHOST=8580922.hostedresource.com
SET DBNAME=MyDatabase
REM set the variables and the SQL
SET VAR_1=777
SET VAR_2=245.67
SET SQL="INSERT INTO `My_Database`.`My_Table` (`VAR_1`,`VAR_2`) VALUES ( '%VAR_1%',
'%VAR_2%');"
"%bin%/mysql" -e %SQL% --user=NAME_OF_USER --password=PASSWORD -h %DBHOST% %DBNAME%
PAUSE
Please try that and post back the resulting error message. There are many reasons that it won't work, but you need to try it to find out.
I'm not sure where test.txt comes into this but it would be a good idea export the whole SQL statement to a text file then use the correct MySQL command line switch to just run the file instead of generating the SQL inside the batch file.
There's a bit more here.

OK, here is what I am trying to.
Using MySQL command line, I am running a script and then saving out the data like this:
mysql -h DATABASE -u yyyy -pxxxx < E:/Step_2.sql > E:/OUTPUT_YYYY_QQ.csv
Now, either using MySQL or a Windows batch command, I want the YYYY and QQ to be a specific value. It isn't the current date though. In this example, I want the YYYY to be 2017 and the QQ to be Q4.
I have flexibility to either:
Create a new table in SQL with the values in it if needed. Then with help run a command to use those values as part of the file name.
Or I can place a file on the server somewhere to "reference" in order to grab the data and place it in the file name.
Any thoughts?
Here I have created a shell script called "test.sh", which will generate the file name dynamically, but all you need to convert this shell script into windows batch. It's an idea to you as per your comment.
test.sh
file_name=$(mysql -N -hlocalhost -uvivek -pvivek -e "select concat('OUTPUT_',year(date_column),'_Q',quarter(date_column),'.csv') file_name from table_name")
mysql -hlocalhost -uvivek -pvivek </home/vivekanand/vivek/stack/test.sql >/home/vivekanand/vivek/stack/$file_name
After running the script, I got file created as below with correct output of SQL file "test.sql"
-rw-rw-r-- 1 vivekanand vivekanand 14535 May 7 13:56 OUTPUT_2017_Q4.csv
I am designing an application in Python and trying to write to a CSV file, but I am getting this error:
DatabaseError: 1 (HY000): Can't create/write to file '2015-04-06 20:48:33.418000'.csv (Errcode: 13 - Permission denied)
The Code:
def generate_report(self):
conn=mysql.connector.connect(user='root',password='',host='localhost',database='mydatabase')
exe2 = conn.cursor()
exe2.execute("""SELECT tbl_site.Site_name, State_Code, Country_Code,Street_Address, instrum_start_date, instrum_end_date, Comment INTO OUTFILE %s FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '\\\\' LINES TERMINATED BY '\\n'FROM tbl_site JOIN tbl_site_monit_invent ON site_id = tbl_Site_site_id """, (str(datetime.datetime.now()),))
I can run this code without any errors on a Mac, but I need it to work on Windows.
How can I resolve this error?
Simple really. A colon character is not a valid character in a filename on Windows. It's not allowed.
Reference: https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx
The colon character is in the list of "reserved characters", along with several others. (NOTE: One use of the colon character is as a separator for an Alternate Data Stream on NTFS. Ref: http://blogs.technet.com/b/askcore/archive/2013/03/24/alternate-data-streams-in-ntfs.aspx
Followup
The question has been significantly edited since my previous answer was provided. Some notes:
I'm not very familiar with running MySQL on Windows OS. Most of my work with MySQL server is on Linux.
The SELECT ... INTO OUTFILE statement will cause the MySQL server to attempt to write a file on the server host.
The MySQL user (the user logged in to MySQL) must have the FILE privilege in order to use the SELECT ... INTO OUTFILE statement.
Also, the OS account that is running MySQL server must have OS permissions to write a file to the specified directory, and the file to be written must not already exist. Also, the filename must conform to the naming rules for filenames on OS filesystem.
Ref: https://dev.mysql.com/doc/refman/5.5/en/select-into.html
For debugging this type of issue, I strongly recommend you echo out the actual SQL text that is going to be sent to the MySQL server. And then take that SQL text and run it from a different client, like the mysql command line client.
For debugging a privileges issues, you can use a much simpler statement. Test writing a file to a directory that is known to exist, that is known the mysql server has permissions to write files to, and with a filename that does not exist and that conforms to the rules for the OS and filesystem.
For example, on a normal Linux box, we could test with something like this:
mysql> SELECT 'bar' AS foo INTO OUTFILE '/tmp/mysql_foo.csv'
Before we run that, we can easily verify that the /tmp directory exists, that it is writable by the OS account that is running the mysql server, and that the filename conforms to the rules for the filesystem, and that the filename doesn't exist, e.g.
$ su - mysql
$ ls -l /tmp/mysql_foo.csv
$ echo "foo" >/tmp/mysql_foo.csv
$ cat /tmp/mysql_foo.csv
$ rm /tmp/mysql_foo.csv
$ ls -l /tmp/mysql_foo.csv
Once we get over that hurdle, we can move on to testing writing a file to a different directory, a file with a more more complex filename. Once we get that plumbing working, we can work on getting actual data, into a usable csv format.
The original question seems to indicate that the MySQL server is running on Windows OS, and it seems to indicate that the filename attempting to be written contains semicolon characters. Windows does not allow semicolon as part a filename.
It was simply permission error.
I am trying to run the standalone ncbi-blast-2.2.28+ on my machine (Mac) but get this error message when running blastp with SwissProt database:
BLAST Database error: Could not find volume or alias file (nr.00) referenced in alias file (/Users/me/bin/db/swissprot.00).
Here what I did:
1) downloaded the "ncbi-blast-2.2.28+-universal-macosx.tar.gz" from ncbi server and decompressed it
2) move the bin content of the folder to my $PATH directory "/Users/me/bin"
3) In "/Users/me/bin" I created a "db" folder, plus the ".ncbirc" file containing the following path:
[BLAST]
BLASTDB=/Users/me/bin/db
4) I downloaded the SwissProt database and got the following files in "/Users/me/bin/db/:
swissprot.00.msk
swissprot.01.msk
swissprot.02.msk
swissprot.03.msk
swissprot.04.msk
swissprot.05.msk
swissprot.06.msk
swissprot.07.msk
swissprot.08.msk
swissprot.09.msk
swissprot.10.msk
swissprot.00.pal
swissprot.01.pal
swissprot.02.pal
swissprot.03.pal
swissprot.04.pal
swissprot.05.pal
swissprot.06.pal
swissprot.07.pal
swissprot.08.pal
swissprot.09.pal
swissprot.10.pal
swissprot.pal
Then when I run blastp from any working directory (where my query file is), using this command:
blastp -query input.fasta -db swissprot
I get the following error message:
BLAST Database error: Could not find volume or alias file (nr.00) referenced in alias file (/Users/me/bin/db/swissprot.00).
As I read on other threads, I also tried to mention in the command line the whole path where the db is located, and to remove the .pal extension from the file names. But still doesn't work.
Can someone sees what I did wrong ?!!!!
you are storing your database files in db folder so you have to give this command instead of the one you have used:
blastp -query input.fasta -db db/swissprot
and I believe you are looking for an output in the console itself as you haven't used the -out option.
Also this will work only if the bin directory in which db folder is present be declared as an environment variable.
Have you checked the paths in .pal file?
Swissprot database that you have downloaded contains only links to entries in nr database: "nr - Non-redundant GenBank CDS translations + PDB + SwissProt + PIR + PRF, excluding those in env_nr". So you should additionally download nr database to run the standalone blast on your machine with SwissProt database. It weighs about 20 (!) Gb, but without it your blast will not work. Here's a link: ftp://ftp.ncbi.nlm.nih.gov/blast/db/
place all files from 00 to 10 folders into db and then check .pal file should contain 00 to 10 parts for example for nr databas its like
"nr.00" "nr.01" "nr.02" "nr.03" "nr.04" "nr.05" "nr.06" "nr.07" "nr.08" "nr.09" "nr.10"
I know you use the spool command when you are trying to write a report to a file in Oracle SQLplus.
What is the equivalent command in MySQL?
This is my code:
set termout off
spool ${DB_ADMIN_HOME}/data/Datareport.log # ${DB_ADMIN_HOME}/Scripts.Datavalidation/Datareportscript.sql
spool off
exit
How can I write it in MySQL?
In MySQL you need to use the commands tee & notee:
tee data.txt;
//SQL sentences...
notee;
teedata.txt == spooldata.txt
notee == spool off
For the Oracle SQLPlus spool command, there is no equivalent in the mysql command line client.
To get output from the mysql command line client saved to a file, you can have the operating system redirect the output to a file, rather than to the display.
In Unix, you use the > symbol on the command line. (It seems a bit redundant here to give an example of how to redirect output.)
date > /tmp/foo.txt
That > symbol is basically telling the shell to take what is written to the STDOUT handle and redirect that to the named file (overwriting the file if it exists) if you have privileges.
Q: is set pagesize and set linesize used in mysql when you are trying to generate a report?
A: No. Those are specific to Oracle SQLPlus. I don't know of any equivalent functionality in the mysql command line client. The mysql command line client has some powerful features when its run in interactive mode (e.g. pager and tee), but in non-interactive mode, it's an inadequate replacement for SQLPlus.
If I get what you are asking:
mysql dbname < ${DB_ADMIN_HOME}/Scripts.Datavalidation/Datareportscript.sql \
> ${DB_ADMIN_HOME}/data/Datareport.log
Use redirection.
I have a script that I need to execute using a batch file. Do I use SQLCMD in the batch file to run the script? Also, the script inserts data to a table in a database. How should I format the SQLCMD in the batch file so it knows what database it is suppose to work with?
First, save your query into an sql text file (text file with .sql extension). Make sure to add the USE statement at the beginning, which tells the server which database you want to work with. Using the example from MSDN:
USE AdventureWorks2008R2;
GO
SELECT p.FirstName + ' ' + p.LastName AS 'Employee Name',
a.AddressLine1, a.AddressLine2 , a.City, a.PostalCode
FROM Person.Person AS p
INNER JOIN HumanResources.Employee AS e
ON p.BusinessEntityID = e.BusinessEntityID
INNER JOIN Person.BusinessEntityAddress bea
ON bea.BusinessEntityID = e.BusinessEntityID
INNER JOIN Person.Address AS a
ON a.AddressID = bea.AddressID;
GO
Then in your batch file, you run SQLCMD and pass it the sql file (with path) as a parameter.
sqlcmd -S myServer\instanceName -i C:\myScript.sql
If you need to authenticate as well, you'll need to add in -U and -P parameters to your SQLCMD command.
Here's an MSDN article dealing with the sqlcmd utility with more details.
Use the -S switch to specify server and instance names, e.g. -S MyDbServer\Database1
SQLCMD documentation found here.
If you want to execute all .sql files (multiple sql scripts in a folder) for multiple database then create a batch file "RunScript-All.bat" with below content
echo "======Start - Running scripts for master database======="
Call RunScript-master.bat
echo "=======End - Running scripts for master database=========="
pause
echo "=====Start - Running scripts for model database========"
Call RunScript-model.bat
echo "=======End - Running scripts for master database=========="
pause
Definition for individual batch file for a specific database i.e. "RunScript-master.bat" can be written as per below
for %%G in (*.sql) do sqlcmd /S .\SQL2014 /U sa /P XXXXXXXXX /d master -i"%%G"
::pause
Create many files for different databases and call them from "RunScript-All.bat".
Now you will be all to run all sql scripts in many database by clicking on "RunScript-All.bat" batch file.
