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.

shell configuration.
The following shell commands are available:
- \ Start multi-line input when in SQL mode.
- \connect (\c) Connects the shell to a MySQL server and assigns the
global session.
- \disconnect Disconnects the global session.
- \edit (\e) Launch a system editor to edit a command to be executed.
- \exit Exits the MySQL Shell, same as \quit.
- \G Send command to mysql server, display result vertically.

- \history View and edit command line history.
- \nopager Disables the current pager.
- \nowarnings (\w) Don't show warnings after every statement.
- \option Allows working with the available shell options.
- \pager (\P) Sets the current pager.
- \py Switches to Python processing mode.
- \quit (\q) Exits the MySQL Shell.
- \reconnect Reconnects the global session.
- \rehash Refresh the autocompletion cache.
- \show Executes the given report with provided options and
arguments.
- \source (\.) Loads and executes a script from a file.
- \sql Executes SQL statement or switches to SQL processing
mode when no statement is given.
- \status (\s) Print information about the current global session.
- \system (\!) Execute a system shell command.
- \use (\u) Sets the active schema.

needed to add apt-package for mysql
everything working fine now.

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.
connecting to MySQL from the command line
I’m trying to run/load sql file into mysql database using this golang statement but this is not working:
exec.Command("mysql", "-u", "{username}", "-p{db password}", "{db name}", "<", file abs path )
But when i use following command in windows command prompt it’s working perfect.
mysql -u {username} -p{db password} {db name} < {file abs path}
So what is the problem?
As others have answered, you can't use the < redirection operator because exec doesn't use the shell.
But you don't have to redirect input to read an SQL file. You can pass arguments to the MySQL client to use its source command.
exec.Command("mysql", "-u", "{username}", "-p{db password}", "{db name}",
"-e", "source {file abs path}" )
The source command is a builtin of the MySQL client. See https://dev.mysql.com/doc/refman/5.7/en/mysql-commands.html
Go's exec.Command runs the first argument as a program with the rest of the arguments as parameters. The '<' is interpreted as a literal argument.
e.g. exec.Command("cat", "<", "abc") is the following command in bash: cat \< abc.
To do what you want you have got two options.
Run (ba)sh and the command as argument: exec.Command("bash", "-c", "mysql ... < full/path")
Pipe the content of the file in manually. See https://stackoverflow.com/a/36383984/8751302 for details.
The problem with the bash version is that is not portable between different operating systems. It won't work on Windows.
Go's os.exec package does not use the shell and does not support redirection:
Unlike the "system" library call from C and other languages, the os/exec package intentionally does not invoke the system shell and does not expand any glob patterns or handle other expansions, pipelines, or redirections typically done by shells.
You can call the shell explicitly to pass arguments to it:
cmd := exec.Command("/bin/sh", yourBashCommand)
Depending on what you're doing, it may be helpful to write a short bash script and call it from Go.

It is kind of strange that script works fine when run manually when it runs using /etc/xinetd.d/ , it is not working as expected.
In mysqlclustercheck script, instead of using --user= and passord= syntax, I am using --login-path= syntax
script runs fine when I run using command line but status for xinetd was showing signal 13. After debugging, I have found that even simple command like this is not working
mysql_config_editor print --all >>/tmp/test.txt
We don't see any output generated when it is run using xinetd ( mysqlclustercheck)
Have you tried the following instead of /usr/bin/mysqlclustercheck?
server = /usr/bin/clustercheck
I am wondering if you could test your binary location with the linux which command.
A long time ago since this question was asked, but it just came to my attention.
First of all as mentioned, Percona Cluster Control script is called clustercheck, so make sure you are using the correct name and correct path.
Secondly, since the server script runs fine from command line, it seems to me that the path of mysql client command is not known by the xinetd when it runs the Cluster Control script.
Since the mysqlclustercheck script as it is offered from Percona, it uses only the binary name mysql without specifying the absolute path I suggest you do the following:
Find where mysql client command is located on your system:
ccloud#gal1:~> sudo -i
gal1:~ # which mysql
/usr/local/mysql/bin/mysql
gal1:~ #
then edit script /usr/bin/mysqlclustercheck and in the following line:
MYSQL_CMDLINE="mysql --defaults-extra-file=$DEFAULTS_EXTRA_FILE -nNE --connect-timeout=$TIMEOUT \
place the exact path of mysql client command you found in the previous step.
I also see that you are not using MySQL connection credentials for connecting to MySQL server. mysqlclustercheck script as it is offered from Percona, it uses User/Password in order to connect to MySQL server.
So normally, you should execute the script in the command line like:
gal1:~ # /usr/sbin/clustercheck haproxy haproxyMySQLpass
HTTP/1.1 200 OK
Content-Type: text/plain
Where haproxy/haproxyMySQLpass is the MySQL connection user/pass for HAProxy monitoring user.
Additionally, you should specify them to your script's xinetd settings like:
server = /usr/bin/mysqlclustercheck
server_args = haproxy haproxyMySQLpass
Last but not least, the signal 13 you are getting is because you try to write something in a script run by xinetd. If for example in your mysqlclustercheck you try to add a statement like
echo "debug message"
you probably going to see the broken pipe signal (13 in POSIX).
Finally, I had issues with this script using SLES 12.3 and I finally manage to run it not as 'nobody' but as 'root'.
Hope it helps
I am having real issues with a .db file its around 20gb in size with three tables and the rest data.
I am on a mac so i am having to use some crappy apps but it wont open in Access.
Does any one know what software will produce a .db file and what software will allow me to open it and export it as a CSV or MySQL file ?
Also if the connection was interrupted during transit could this effect the file ?
Since mac is BSD-based now, try opening a terminal and executing the command file /path/to/large/db -- it should tell you at least what file type the DB is, and from there you can determine what program to use to open it. It might be MySQL, might be PostGreSQL, might be SQLite -- file will tell you.
Example:
$ file a.db
a.db: SQLite 3.x database
$ file ~/.kde/share/apps/amarok/mysqle/amarok/tracks.{frm,MYD,MYI}
~/.kde/share/apps/amarok/mysqle/amarok/tracks.frm: MySQL table definition file Version 10
~/.kde/share/apps/amarok/mysqle/amarok/tracks.MYD: data
~/.kde/share/apps/amarok/mysqle/amarok/tracks.MYI: MySQL MISAM compressed data file Version 1
So it's SQLite v3? Then try
sqlite3 /path/to/db
and you can perform pretty much standard SQL from the CLI. At the CLI, you can type .tables to list all the tables in that DB. -- Or if you prefer a GUI, there are a few options listed in this question. Accepted answer was SQLite manager for Firefox.
Then you could drop tables or delete as you see fit.
Here's an example of dumping a csv to stdout:
$ sqlite3 -separator ',' -list a.db "SELECT * FROM t"
3,4
3,5
100,200
And to store it to a file -- the > operator redirects output to a file you name:
$ sqlite3 -separator ',' -list a.db "SELECT * FROM t" > a.csv
$ cat a.csv # puts the contents of a.csv on stdout
3,4
3,5
100,200
-separator ',' indicates that fields should be delimited by a comma; -list means to put row data on the same line, using the delimiter; a.db indicates which db to use; and "SELECT * FROM t" is just the SQL command to execute.
I'm not a Mac user but if it's a SQLite file I've heard great things about Base.
