Is there a way to have a .csv or .txt imported into SQL Server automatically?
I know how to do it manually using Date import & Export tool. But is it possible to do it automatically?
You can use Windows Task Scheduler to run bcp commands automatically. The command that will be run automatically will import your csv file using bulk copy program (bcp) utility. It can import or export data from/to files. For example to import a csv file to a table in SQL Server, you can use command like this:
bcp.exe dbo.MyTable in "C:\Some Folder\Data.csv" -s MYPC\SQLEXPRESS -d MyDatabase -U LoginName -P StrongP#ssw0rd
Where:
dbo.MyTable is the schema and table name, where data should be imported.
in tells the direction (put data in the database, or get data out of it).
"C:\Some Folder\Data.csv" is the name and path to the file holding the data to be imported.
MYPC\SQLEXPRESS is the computer and SQL Server instance name.
MyDatabase is the name of the database, where dbo.MyTable is.
LoginName and StronP#ssw0rd are the credentials to be used to connect to the server (or -E instead of -U and -P to connect using Windows Authentication).
Then create a new scheduled task (Start -> Task Scheduler -> Create Basic Task) and set a schedule according your requirements (e.g. daily at 3:00 AM) to run the command above.

I have a .sql file with a content of insert queries for all tables of my database.
This file is 12 GB in size. I tried to open it with Notepad++, SQL Server Management Studio, and also with chrome browser, but the file is very long. I cant' open it.
How can I import it into my database directly without opening the file and execute the queries?
What is the proper way to do this?
you need to use sqlcmd , the documentation has a full explanation of how to use it but here is a quick sample how to use it, you need to install sqlcmd utility first then open up your cmd command prompt and type the command like this :
sqlcmd -S DBSERVER\TESTINSTANCE -d DATABASENAME -U USERNAME -P PASSWORD -i "D:/InsertData.sql"
I'm trying to import data from .csv file to a PostgreSQL database hosted in a Linux Server, using the following command:
COPY areas_brasil FROM 'C:/Temp/RELATORIO_DTB_BRASIL_MUNICIPIO.csv' with delimiter '|' null 'NULL';
But i'm receiving the following error:
ERROR: could not open file
"C:/Temp/RELATORIO_DTB_BRASIL_MUNICIPIO.csv" for reading: No such file
or directory TIP: COPY FROM instructs the PostgreSQL server process
to read a file. You may want a client-side facility such as psql's
\copy.
The .csv file is in a client computer (running on Windows 10) in which i have administrator access to the database hosted in the server (running on Linux - Debian).
Thanks for helping me!
Welcome to SO.
COPY .. FROM 'path' assumes that the file is located in the server. If you wish execute COPY without having the file into the database server, you can either use \copy or just use the STDIN of psql from your client console, e.g. in unix systems (you have to find the cat and | equivalent for Windows):
$ cat file.csv | psql yourdb -c "COPY areas_brasil FROM STDIN DELIMITER '|';"
Using \COPY inside of psql it can be done like this:
\COPY areas_brasil FROM '/home/jones/file.csv' DELIMITER '|';
See this answer for more details.
Files are being written to a directory using the COPY query:
Copy (SELECT * FROM animals) To '/var/lib/postgresql/data/backups/2020-01-01/animals.sql' With CSV DELIMITER ',';
However if the directory 2020-01-01 does not exist, we get the error
could not open file "/var/lib/postgresql/data/backups/2020-01-01/animals.sql" for writing: No such file or directory
PostgeSQL server is running inside a Docker container with the volume mapping /mnt/backups:/var/lib/postgresql/data/backups
The Copy query is being sent from a Node.js app outside of the Docker container.
The mapped host directory /mnt/backups was created by Docker Compose and is owned by root, so the Node.js app sending the COPY query is unable to create the missing directories due to insufficient permissions.
The backup file is meant to be transferred out of the Docker container to the Docker host.
Question: Is it possible to use an SQL query to ask PostgreSQL 11.2 to create a directory if it does not exist? If not, how will you recommend the directory creation be done?
Using Node.js 12.14.1 on Ubuntu 18.04 host. Using PostgreSQL 11.2 inside container, Docker 19.03.5
An easy way to solve it is to create the file directly into the client machine. Using STDOUT from COPY you can let the query output be redirected to the client standard output, which you can catch and save in a file. For instance, using psql in the client machine:
$ psql -U your_user -d your_db -c "COPY (SELECT * FROM animals) TO STDOUT WITH CSV DELIMITER ','" > file.csv
Creating an output directoy in case it does not exist:
$ mkdir -p /mnt/backups/2020-01/ && psql -U your_user -d your_db -c "COPY (SELECT * FROM animals) TO STDOUT WITH CSV DELIMITER ','" > /mnt/backups/2020-01/file.csv
On a side note: try to avoid exporting files into the database server. Although it is possible, I consider it a bad practice. Doing so you will either write a file into the postgres system directories or give the postgres user permission to write somewhere else, and it is something you shouldn't be comfortable with. Export data directly to the client either using COPY as I mentioned or follow the advice from #Schwern. Good luck!
Postgres has its own backup and restore utilities which are likely to be a better choice than rolling your own.
When used with one of the archive file formats and combined with pg_restore, pg_dump provides a flexible archival and transfer mechanism. pg_dump can be used to backup an entire database, then pg_restore can be used to examine the archive and/or select which parts of the database are to be restored. The most flexible output file formats are the “custom” format (-Fc) and the “directory” format (-Fd). They allow for selection and reordering of all archived items, support parallel restoration, and are compressed by default. The “directory” format is the only format that supports parallel dumps.
A simple backup rotation script might look like this:
#!/bin/sh
table='animals'
url='postgres://username#host:port/database_name'
date=`date -Idate`
file="/path/to/your/backups/$date/$table.sql"
mkdir -p `dirname $file`
pg_dump $url -w -Fc --table=$table -f $file
To avoid hard coding the database password, -w means it will not prompt for a password and instead look for a password file. Or you can use any of many Postgres authentication options.
I have a .sql dump file 20 gb and I am trying to run it on Mysql workbench using run script and after successful execution, using SSMA I'll migrate the data from Mysql workbench to SQL Server. I have migrated the data this way many times successfully however for 20 gb file it seems very time-consuming. Please let me know if there is any alternate way to achieve this quickly. I have followed the following link:
Steps to migrate mysql tables to sql server using SSMA!
From your Title "unable to run .sql file in SSMS" and "I have a .sql dump file 20 gb" are you trying to open a 20GB .sql in SSMS? That's never going to work. SSMS is a 32bit application, so the maximum addressable memory is 2GB. If you want to run your .sql file, I suggest using sqlcmd.
Open up Powershell, and then run the command below replacing the appropriate parts:
sqlcmd -S {Server Name/ServerIP} -U {Your Login} -i {Your full path to your script}
You'll be prompted for your password and then you the file will be run. So, as an example, you might run:
sqlcmd -S svSQL2017 -U Larnu -i \\svFileServer\SQLShare\Scripts\BigBatchFile.sql
If you are using integrated security, then don't pass the -U parameter for the command.
Edit: This answer is no relevant to the OPs question, as they were using "SSMS" as a synonym for SQL Server, which it is not. I have left this here for the moment so the OP can review my comments, and I will likely remove this answer at a later point.
I deploy some .bteq and .sql scripts on a TERADATA database. For doing this, I use a client on my desktop called BTEQWin version 13.10.0.03.
I get the .bteq/.sql from a version control like pvcs/svn etc and all I do once the files are in my workspace folder (from Version control tool), to just drag and drop the files from Windows browser to BTEQWin client (which I connect to a database prior to drag/drop for running those scripts).
Now, I have to automate this whole process in UNIX.
I have written a SHELL KSH/BASH script which is getting all the .bteq/.sql from a TAG/LABEL in the version control tool to a given UNIX folder. Now, all I need to do is the pass these files one by one (i'll take care of the order) to Teradata client.
My ?
- what client do I need to tell Unix admin team to install on Unix server - so that I can run something like below:
someTeraDataCommand -u username -p password -h hostname -d database -f filenametoexectue | tee output_filename.log
Where, someTeraDataCommand is the client / executable - which will let me run Teradata scripts (like I was doing using BTEQWin on my desktop - GUI session). Other parameters can be username, password, which database to connect on what server and which file to run or make that file passed to the command using "<" operator at command line.
Any idea?
- What client ?
Assuming the complete Teradata Tools and Utilities package is installed on your UNIX server (which will have the connectivity tools to talk to Teradata), you should have access to bteq from the command line. Something like this:
bteq < script_file > output_file
Your script file should contain a .LOGON statement to establish the connection:
.LOGON yourTDPID/your_account,your_pw
You might also need to use other commands to set your default database or non-default session values.
Another option would be to combine the SQL and call to BTEQ in a Korn shell script:
#!/usr/bin/ksh
##############
SHELL_NAME=`basename $0`
PRG_NAME=`basename $(SHELL_NAME} .ksh`
LOG_FILE=${PRG_NAME}.log
OUT_FILE=${PRG_NAME}.out
#
bteq <<EOBTQ > ${LOG_FILE} 2>$1
.LOGON {TDPID}/{USERID},{PWD};
--.RUN file=${LOGON}
/* Add your SQL/BTEQ commands here */
.QUIT 0;
EOBTQ
Edit
The double hyphen indicates a single line comment. Typically in a UNIX script you do not leave your password in plain text of a KSH script. The .RUN command would reference a text file in a barely sufficient secure location containing the .LOGON {TPDID}/{USERID},{PWD}; command.
The .RUN command in BTEQ allows you to reference another text file containing a series of valid BTEQ commands that you want to run in the current BTEQ script.
Easiest way is to setup the Solaris TTU, is to request root sudo, and run an interactive installation into defaults as a root. That would cure all client issues.
