I have a script that needs to connect to oracle db hosted on a different server .I am able to connect to this oracle db using sqldeveloper.But i am not able to configured it in my bash script .
SQLDEVELOPER 4.0 is the tool that i use to connect through gui .How can i use this in my script .Is there any other way to do it ?Do i need any other software (sqlplus)
try using following once:
sqlplus db_user_name/password_for_user#DB_schema < Input_file.sql > Output
You need sqlplus to achieve what you're trying to do. The syntax of the command you need to put in you shell script should be like:
sqlplus 'USER/PASSWORD#(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=DB_HOST)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=SERVICE_NAME_YOU_USE_IN_SQLDEVELOPER)))'
On *nix systems, this will create a csv stream of results to standard out:
java -Djava.security.egd=file///dev/urandom -jar jdbcsql.jar -d oracledb_SID -h $host -p 1521 -U some_username -m oracle -P "$PW" -f excel -s "," "$1"
Note that adding the -Djava.security.egd=file///dev/urandom increases performance greatly
Windows commands are similar: see http://jdbcsql.sourceforge.net/

I'm trying to run my query without the need to have SSMS open and running. Previously I've used this connecting to SQL server database via SQLMCD utility to run batches. However, this query I am now using is in MDX so I am not sure on how that translates for a connection to analysis server. This is what I've used in the past to execute the query:
echo StartTimeStamp > "%~dp0\StartTimeStamp.txt"
sqlcmd -S businesspublish -d revcube -G -i "%~dp0\Step 1 - modify query.mdx" -o "%~dp0\Step 3 - Query
results in CSV format.csv" -s"," -w 700 -I -t 28800 -h-1
echo EndTimeStamp > "%~dp0\EndTimeStamp.txt"
#set /p delExit=Press the ENTER key to exit...:
This was written by a former colleague and I'm trying to recycle it, to execute the query with the following details:
ServerName: Businesspublish
Database:RevCube
Query file name: Step 1 - modify query.mdx
Step 3 - Query results in CSV format.csv
Any help would be highly appreciated. Thanks!
Try the ASCMD utility. The folloing link explain how you can use XMLA, MDX,DMX on cube

I have a file that contains several SQL queries.
Can I somehow run them via isql (I'm doing the calls from Bash script, so no access to Perl DBI or JDBC)
I tried piping them into isql command via echo /my/file | isql -my-other-parameters but that didn't work.
Yes.
If you're running ISQL in interactive mode, you can load an entire contents of the file using :r my-filename command from > prompt.
From Bash script, it's also possible to do - but you need to carefully make sure that
The SQL file you are piping in has a go statement at the end. That is a VERY common cause of issues like the one you mentioned.
That statement has a newline after it.
From a script, you can do it 2 ways: Pass on STDIN via a pipe/redirect; OR, pass in the file name via isql's -i parameter
In my case it was isq -n for a piped query to work.
isql -U $DB_USR -P $DB_PWD -S $DB_PATH -D $DB_NAME -w 500 < $FILE
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'm looking to be able to run a single query on a remote server in a scripted task.
For example, intuitively, I would imagine it would go something like:
mysql -uroot -p -hslavedb.mydomain.com mydb_production "select * from users;"
mysql -u <user> -p -e 'select * from schema.table'
(Note the use of single quotes rather than double quotes, to avoid the shell expanding the * into filenames)
mysql -uroot -p -hslavedb.mydomain.com mydb_production -e "select * from users;"
From the usage printout:
-e, --execute=name
Execute command and quit. (Disables --force and history file)
here's how you can do it with a cool shell trick:
mysql -uroot -p -hslavedb.mydomain.com mydb_production <<< 'select * from users'
'<<<' instructs the shell to take whatever follows it as stdin, similar to piping from echo.
use the -t flag to enable table-format output
If it's a query you run often, you can store it in a file. Then any time you want to run it:
mysql < thefile
(with all the login and database flags of course)
echo "select * from users;" | mysql -uroot -p -hslavedb.mydomain.com mydb_production
As by the time of the question containerization wasn't that popular, this is how you pass a single query to a dockerized database cluster with Ansible, following #RC.'s answer:
ansible <host | group > -m shell -a "docker exec -it <container_name | container_id> mysql -u<your_user> -p<your_pass> <your_database> -e 'SELECT COUNT(*) FROM my_table;'"
If not using Ansible, just login to the server and use docker exec -it ... part.
MySQL will issue a warning that passing credentials in plain text may be insecure, so be aware of your risks.
From the mysql man page:
You can execute SQL statements in a script file (batch file) like this:
shell> mysql db_name < script.sql > output.tab
Put the query in script.sql and run it.
I have some SQL scripts that I'm trying to automate. In the past I have used SQL*Plus, and called the sqlplus binary manually, from a bash script.
However, I'm trying to figure out if there's a way to connect to the DB, and call the script from inside of the bash script... so that I can insert date and make the queries run relative to a certain number of days in the past.
I'm slightly confused. You should be able to call sqlplus from within the bash script. This may be what you were doing with your first statement
Try Executing the following within your bash script:
#!/bin/bash
echo Start Executing SQL commands
sqlplus <user>/<password> #file-with-sql-1.sql
sqlplus <user>/<password> #file-with-sql-2.sql
If you want to be able to pass data into your scripts you can do it via SQLPlus by passing arguments into the script:
Contents of file-with-sql-1.sql
select * from users where username='&1';
Then change the bash script to call sqlplus passing in the value
#!/bin/bash
MY_USER=bob
sqlplus <user>/<password> #file-with-sql-1.sql $MY_USER
You can also use a "here document" to do the same thing:
VARIABLE=SOMEVALUE
sqlplus connectioninfo << HERE
start file1.sql
start file2.sql $VARIABLE
quit
HERE
Here is a simple way of running MySQL queries in the bash shell
mysql -u [database_username] -p [database_password] -D [database_name] -e "SELECT * FROM [table_name]"
Maybe you can pipe SQL query to sqlplus. It works for mysql:
echo "SELECT * FROM table" | mysql --user=username database
I've used the jdbcsql project on Sourceforge.
On *nix systems, this will create a csv stream of results to standard out:
java -Djava.security.egd=file///dev/urandom -jar jdbcsql.jar -d oracledb_SID -h $host -p 1521 -U some_username -m oracle -P "$PW" -f excel -s "," "$1"
Note that adding the -Djava.security.egd=file///dev/urandom increases performance greatly
Windows commands are similar: see http://jdbcsql.sourceforge.net/
If you do not want to install sqlplus on your server/machine then the following command-line tool can be your friend. It is a simple Java application, only Java 8 that you need in order to you can execute this tool.
The tool can be used to run any SQL from the Linux bash or Windows command line.
Example:
java -jar sql-runner-0.2.0-with-dependencies.jar \
-j jdbc:oracle:thin:#//oracle-db:1521/ORCLPDB1.localdomain \
-U "SYS as SYSDBA" \
-P Oradoc_db1 \
"select 1 from dual"
Documentation is here.
You can download the binary file from here.
As Bash doesn't have built in sql database connectivity... you will need to use some sort of third party tool.
