Command for executing the MySQL stored procedures using command prompt also required to reduce the size of output history on a console window.
Update:
There is already a similar question with excellent answers on the CALL'ing part.
To run stored procedures from the command line, use the -e option of the mysql client. Example, to call a SP "foo", from bash, you'd do:
bash> mysql -e "call foo()" dbname
If you do not want the command to be stored in the history file, add a space before the mysql command, thusly:
bash> mysql -e "call foo()" dbname
^
|_ space

Want to Execute a MYSQL Stored Procedure in shell script
Example : Employee_config ('ClientId','Data') is Procedure name in my sql
When i try to give in the shell script as below
CALL Employee_config ('ClientId','Data') we are getting CALL: command not found
EXECUTE Employee_config ('ClientId','Data') we are getting EXECUTE: command not found
So would be great if someone can have an update on the same on how to call MySQL stored procedure from shell script
You can try to call it using the mysql command:
mysql -u root –ppassword -e 'call test_procedure();' Databasename
you can follow that with a > out.txt to capture the output into a file.
You can try the below way...
#!/usr/bin/bash
#Script to run automated sql queries
#Declaring mysql DB connection
MASTER_DB_USER='root'
MASTER_DB_PASSWD='root'
MASTER_DB_PORT='3160'
MASTER_DB_HOST='192.168.0.0'
MASTER_DB_NAME='MyDB'
startDate='2018-03-09'
endDate='2018-03-09'
#Prepare sql query
SQL_Query1='select * from mytable limit 1'
SQL_Query2='call carServicedQry'
SQL_Query3='call carServicedQry2("2018-03-09","2018-03-09")'
#mysql command to connect to database
MYSQL -u$MASTER_DB_USER -p$MASTER_DB_PASSWD -D$MASTER_DB_NAME <<EOF
$SQL_Query2
EOF
echo "End of script"
and execute the script like ./myscript.sh
I'm writing a bash script to do some db stuff. New to MySQL. I'm on Mac and have MySQL installed via homebrew.
Am using username "root" right now and there isn't a pw set. I included the pw syntax below just to help others out that may have a pw.
My goal is to have mysql commands be as "clean" as possible in my bash script
Not a hige deal, but would like to do this if possible.
Example
# If I can do it without logging in (*ideal)
mysql CREATE DATABASE dbname;
# Or by logging in with - mysql -u root -pPassword
CREATE DATABASE dbname;
# Instead of
mysql -u root -pPassword -e"CREATE DATABASE dbname";
Tried to simplify it. I have a handful of things I gotta do, so would rather keep my code cleaner if possible. I tried logging in with the bash script, but the script stopped once logged into MySQL and didn't run any commands.
Another option I was considering (but don't really like) would be just to keep username and pw string in a var and call it for every commmand like so
# Set the login string variable
login_details="-u root -p password -e"
# example command
mysql $login_details"CREATE DATABASE dbname";
So any ideas?
Write a new bash script file and run this file after putting all your commands into it. Don't forget to give right username and password in your bash script.
For bash script:
#!/bin/bash
mysql -u root -pSeCrEt << EOF
use mysql;
show tables;
EOF
If you want to run single mysql command.
mysql -u [user] -p[pass] -e "[mysql commands]"
Example:
mysql -h 192.168.1.10 -u root -pSeCrEt -e "show databases"
To execute multiple mysql commands:
mysql -u $user -p$passsword -Bse "command1;command2;....;commandn"
Note: -B is for batch, print results using tab as the column separator, with each row on a new line. With this option, mysql does not use the history file. Batch mode results in nontabular output format and escaping of special characters. -s is silent mode. Produce less output. -e is to execute the statement and quit
I am creating a database in a shell script using
mysql -u$username -p$password -e " create database testdb"
I want to store the result of this statement to make decisions in shell script based on its success or failure.
Even during insert statements i do not get any return value
how can is store the result after executing create database / insert statements in shell script?
use the following command substitution syntax:
var=$(command-name-here arg1 arg2...)
So for your command you can do something like this,
output=$(mysql -u$username -p$password -e " create database testdb")
echo "$output"
i am trying to rewrite a script that is written in c-shell script to that uses sql plus command to get information from an oracle database but i am replacing it with mysql and i would like to replace all sqlplus syntax with mysql syntax. I am asking all the c-shell gurus to explain to me what this command means
set SQLPLUS=${ORACLE_HOME}/bin/sqlplus
set REPORT=${MYBD_HOME}/Scripts/report.sql
so somewhere along the line i invoke the sql plus command using the follwing
${SQLPLUS} ${MYDBUSER} # &{REPORT}
i am able to say i undertand what the right hand values mean ({ORACLE_HOME}/bin/sqlplus) is the path to where my sqplus command is located and thus i need it to invoke the command and the {REPORT=$(MYBD_HOME}/Scripts.report.sql) is the path where my sql script that is to be ran by invoking the sqplus command resides correct?
what i dont understand is what the set command is initializing this to. is SQLPLUS a variable so i dont have to type the path when i try to put it in my .csh script?
If so then all i need to do to run this script on a mysql database is simply set the SQLPLUS(problably change it to MYSQL) to point to the path where my msql exec is right
set MYSQL=${MYSQL_HOME}/bin/mysql
then just invoke mysql and run the sql statement
${MYSQL}${MYDBUSER}#${REPORT}
is this what i need to do ro tun the same .tsch script to get data from a mysql table?
You'll need something like this:
${MYSQL} -u $username -p$password -D $database < ${REPORT}
(The username and password are passed in differently to the mysql executable than they are passed to SQLPlus. You'll need to parse out the username and the password from ${MYDBUSER}. Likely, that contains a string such as "scott/tiger". The equivalent on the mysql command line client would be "-u scott -ptiger -D scott".
That # (at sign) is a SQLPlus thing; it tells SQLPLus to read input from the specified filename. The equivalent in mysql would be the source command, e.g.
${MYSQL} -u $username -p$password <_EOD!
use $database
source ${REPORT}
_EOD!
Also, your report.sql file likely includes spool and other SQLPLus specific commands. The mysql command line client is NOT ANYWHERE near as powerful a reporting tool as SQLPlus is.
Addendum:
Q: what exactly does the spool do?
The SQLPlus spool command directs output to a file. It's frequently used to create a log file from a SQLPLus session, and is also useful for creating report files.
set trimspool on
spool /tmp/file.lis
select 'foo' as foo from dual;
spool off
Q: Why can't i set the user name and passowrd to a variable and use that?
You could set a variable, the end result of the command line sent to the OS would be the same.
set MYDBUSER="-u username -ppassword -D database"
${MYSQL} ${MYDBUSER} <${REPORT}
Q:Seems like mysql is more verbose than sqlplus.
The mysql command line client takes unix-style options. These are equivalent:
mysql -u myusername -pmypassword -D mydatabase
mysql --user=myusername --password=mypassword --database=mydatabase
I am trying to create a batch script that would connect to a mySQL database and issue a delete command:
#echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback
delete from competency_question_answer;
I will run this script providing the password as a command-line argument, but all this script does is, connects to the database, and the mysql> prompt will be shown. After I exit from mysql, the rest of the batch commands get to execute (and fail, no surprise).
How can I pass the SQL commands from the batch script to the mysql console? Is this even possible?
You need to use command line tools. I don't know if there exists any for MySQL but for SQL there is SQLCMD and for Oracle there is OSQL.
What you can also do is something like this.
mysql -uuser -ppass < foo.sql
Where foo.sql is the commands you want to execute.
You may need to connect multiple times:
#echo off
echo Resetting all assessments...
mysql -hlocalhost -urdfdev -p%1 rdf_feedback -e delete from competency_question_answer;
Alternatively, you should be able to put all your commands in a separate file such as input.sql and use:
mysql -hlocalhost -urdfdev -p%1 rdf_feedback <input.sql
echo "delete from competency_question_answer;" | mysql -hlocalhost -ur... etc.
Putting multiple sets of commands into .sql batch files works best, and you can execute multiples of these in the .bat file.
