I have a rather simple bash script.
#!/bin/bash
echo
echo What is the root statement for the new debate?
read body
echo
echo What is your mysql password?
read -s pass
echo
sql='INSERT
INTO `Debate` (`unblocked`, `debaterId`, `dirty` )
VALUES ('"'1'"', '"'15'"', '"'0'"' );
INSERT
INTO `Statement` (`body`, `debateId`, `debaterId` )
VALUES ('"'"${body}"'"', LAST_INSERT_ID(), '"'15'"' );'
#echo mysql -u resolution -p ${pass} -D resolution -e \"${sql//[^a-zA-Z0-9(),;\`\'_]/ }\"
mysql -u resolution -p ${pass} -D resolution -e \"${sql//[^a-zA-Z0-9(),;\`\'_]/ }\"
What this is meant to do should be pretty straight forward but it comes down to "ask user for input on terminal... form sql command with the provided input... insert into database in two tables." It's meant to be a quick hack for adding new debates into the database for testing while development is ongoing.
Instead, mysql prints the help as if I had used -?. No error... just the help text. Everything looks correct when the mysql command is echoed to the terminal. And if I copy and paste the echoed command it works just fine. I've searched google and stack overflow but found nothing about this.
U#H ~ mysql --version

Im running the next postgres query using the next bash command.
sudo -u postgres bash -c "psql -d db -c \"SELECT ip FROM db_accounts;\"" \>/dev/null
The output is a table but before the table is printed, I get the following info prints
> psql: /usr/lib64/libssl.so.10: no version information available
> (required by psql) psql: /usr/lib64/libcrypto.so.10: no version
> information available (required by /usr/pgsql-9.4/lib/libpq.so.5)
> psql: /usr/lib64/libssl.so.10: no version information available
> (required by /usr/pgsql-9.4/lib/libpq.so.5)
I want to run my command without these prints appearing.
I tried to change the end of the command >/dev/null to 2>/dev/null and indeed the prints were disable but my table was not fully displayed (out of 800 rows only 40 were displayed),
Can someone help me please?
Use --quiet when you start psql
OR
It can be set in your postgresql.conf file by adding this
client_min_messages = warning
This blog is really helpful.
To fix want I wanted I added --pset pager=off to the psql to get the whole table and the disable the prints I change the end of the command to 2>/dev/null
final command:
sudo -u postgres bash -c "psql --pset pager=off --quiet -d db -c \"SELECT ip FROM db_accounts;\"" 2>/dev/null
I am learning the shell language. I have creating a shell script whose function is to login into the DB and run a .sql file. Following are the contents of the script -
#!/bin/bash
set -x
echo "Login to postgres user for autoqa_rpt_production"
$DB_PATH -U $POSTGRESS_USER $Auto_rpt_production$TARGET_DB -p $TARGET_PORT
echo "Running SQL Dump - auto_qa_db_sync"
\\i auto_qa_db_sync.sql
After running the above script, I get the following error
./autoqa_script.sh: 39: ./autoqa_script.sh: /i: not found
Following one article, I tried reversing the slash but it didn't worked.
I don't understand why this is happening. Because when I try manually running the sql file, it works properly. Can anyone help?
#!/bin/bash
set -x
echo "Login to postgres user for autoqa_rpt_production and run script"
$DB_PATH -U $POSTGRESS_USER $Auto_rpt_production$TARGET_DB -p $TARGET_PORT -f auto_qa_db_sync.sql
The lines you put in a shell script are (moreless, let's say so for now) equivalent to what you would put right to the Bash prompt (the one ending with '$' or '#' if you're a root). When you execute a script (a list of commands), one command will be run after the previous terminates.
What you wanted to do is to run the client and issue a "\i ./autoqa_script.sh" comand in it.
What you did was to run the client, and after the client terminated, issue that command in Bash.
You should read about Bash pipelines - these are the way to run programs and input text inside them. Following your original idea to solving the problem, you'd write something like:
echo '\i auto_qa_db_sync.sql' | $DB_PATH -U $POSTGRESS_USER $Auto_rpt_production$TARGET_DB -p $TARGET_PORT
Hope that helps to understand.
I have a 123MB sql file which I need to execute in my local PC. But I am getting
Cannot execute script: Insufficient memory to continue the execution of the program
How to solve this issue?
use the command-line tool SQLCMD which is much leaner on memory. It is as simple as:
SQLCMD -d <database-name> -i filename.sql
You need valid credentials to access your SQL Server instance or even to access a database
Taken from here.
It might help you! Please see below steps.
sqlcmd -S server-name -d database-name -i script.sql
Open cmd.exe as Administrator.
Create Documents directory.
Put your SQL Script file(script.sql) in the documents folder.
Type query with sqlcmd, server-name, database-name and script-file-name as like above highlighted query or below command line screen.
For Windows Authentication use this sql cmd
SQLCMD -S TestSQLServer\SQLEXPRESS -d AdventureWorks2018 -i "d:\document\sql document\script.sql"
Note: If there is any space in the sql file path then use " (Quotation marks) "
For SQL Server Authentication use this sql cmd
SQLCMD -S TestSQLServer\SQLEXPRESS -U sa -P sasa -d AdventureWorks2018 -i "d:\document\sql document\script.sql"
-S TestSQLServer\SQLEXPRESS: Here specify SQL Server Name
-U sa: Username (in case of SQL Server Authentication)
-P sasa: Password (in case of SQL Server Authentication)
-d AdventureWorks2018: Database Name come here
-i "d:\document\sql document\script.sql": File Path of SQLFile
You can also simply increase the Minimum memory per query value in server properties. To edit this setting, right click on server name and select Properties > Memory tab.
I encountered this error trying to execute a 30MB SQL script in SSMS 2012. After increasing the value from 1024MB to 2048MB I was able to run the script.
(This is the same answer I provided here)
My database was larger than 500mb, I then used the following
C:\Windows>sqlcmd -S SERVERNAME -U USERNAME -P PASSWORD -d DATABASE -i C:\FILE.sql
It loaded everything including SP's
*NB: Run the cmd as Administrator
If I understand your problem correctly, you are trying to restore (transact sql) xyz.sql - database + schema. You can try this command which worked for me:
SQLCMD -U sa -i xyz.sql
Try this step,
1)Open PowerShell
2)Write this command:
sqlcmd -S PCNAME\SQLEXPRESS -U user -P password -d databanse_name -i C:\script.sql
3)Press Return
:-)
Below script works perfectly:
sqlcmd -s Server_name -d Database_name -E -i c:\Temp\Recovery_script.sql -x
Symptoms:
When executing a recovery script with sqlcmd utility, the ‘Sqlcmd: Error: Syntax error at line XYZ near command ‘X’ in file ‘file_name.sql’.’ error is encountered.
Cause:
This is a sqlcmd utility limitation. If the SQL script contains dollar sign ($) in any form, the utility is unable to properly execute the script, since it is substituting all variables automatically by default.
Resolution:
In order to execute script that has a dollar ($) sign in any form, it is necessary to add “-x” parameter to the command line.
e.g.
Original:
sqlcmd -s Server_name -d Database_name -E -i c:\Temp\Recovery_script.sql
Fixed:
sqlcmd -s Server_name -d Database_name -E -i c:\Temp\Recovery_script.sql -x
Sometimes, due to the heavy size of the script and data, we encounter this type of error. Server needs sufficient memory to execute and give the result. We can simply increase the memory size, per query.
You just need to go to the sql server properties > Memory tab (left side)> Now set the maximum memory limit you want to add.
Also, there is an option at the top, "Results to text", which consume less memory as compare to option "Results to grid", we can also go for Result to Text for less memory execution.
sqlcmd -S mamxxxxxmu\sqlserverr -U sa -P x1123 -d QLDB -i D:\qldbscript.sql
Open command prompt in run as administrator
enter above command
"mamxxxxxmu" is computer name
"sqlserverr" is server name
"sa" is username of server
"x1123" is password of server
"QLDB" is database name
"D:\qldbscript.sql" is sql script file to execute in database
If you need to connect to LocalDB during development, you can use:
sqlcmd -S "(localdb)\MSSQLLocalDB" -d dbname -i file.sql
As in most answers given here use the command-line tool. In my case the script already has database creation code. If your script contains CREATE DATABASE command, for example
USE [master]
GO
CREATE DATABASE [your-database-name]
Then do not use the -d your-database-name, instead use the following command.
For Windows Authentication use the command
sqlcmd -S ServerName\InstanceName -i "script.sql" -x
For SQL Server Authentication use the command
sqlcmd -S ServerName\InstanceName -U usename -P password -i "script.sql" -x
I have a bash shell deployment script (linode stackscript) which runs when I deploy my debian 6.0 server. The script runs as root and the script is as follows:
apt-get update
apt-get install postgresql postgresql-contrib pgadmin3
passwd postgres
su - postgres
psql -c "ALTER USER postgres WITH PASSWORD 'changeme'" -d template1
su - postgres
createdb mytestdb
psql mytestdb
I have two problems:
Firstly, when I run each line manually through shell it works, but when I run it as the stackscript it runs the line passwd postgres but nothing after it.
Secondly, when I run the line passwd postgres it asks me to put in my password manually. Is there any way I can put it in as a variable in the shellscript?
passwd is meant to be used interactively.
The proper command to change a password in a batch is chpasswd.
Example:
#!/bin/sh
echo 'postgres:newpassword' | chpasswd
Also note that the way your script does su - postgres does not look like it's normally done in non-interactive mode.
Better do: su -c 'command1; command2...' - postgres
