I'm attempting to write a bash script that will dump a database and then import it to a staging database. I would like the staging database to match the 'master' database.
I have the following code, however I recieve:
ERROR 1062 (23000) at line 23: Duplicate entry '1' for key 'PRIMARY'
# Dump production master database, excluding school_hosts table
mysqldump -h $MYSQL_HOST -u $MYSQL_USERNAME -p$MYSQL_PASSWORD --no-create-info --ignore-table=hcl_master.school_hosts hcl_master > hcl_master.sql
# Dump hcl staging database, for backup.
mysqldump -h $MYSQL_HOST -u $MYSQL_USERNAME -p$MYSQL_PASSWORD hclstaging_master > hclstaging_master_backup.sql
# Import dump file into staging master database
mysql -h $MYSQL_HOST -u $MYSQL_USERNAME -p$MYSQL_PASSWORD hclstaging_master < hcl_master.sql
After searching, I found that I could add --replace to the mysql command that is importing, however I recieve an error stating that:
mysql: unknown option '--replace'
Can anybody help with getting this script to work correctly? I'm unsure how I can drop the staging database before i import or how to get it to overwrite the primary key record?
Any help would be much appreciated. I am using MariaDB.
--replace is a mysqldump option that you specify when creating the dump, not something you can tell mysql when importing the dump.

How do I issue commands to MariaDB via the CLI without actually jumping into the interactive use mode?
I know I can type mysql which will then jump me into the interactive mode where I can write SQL commands like CREATE DATABASE dbname; and then exit to go back to the regular terminal.
However I'd like to skip that and do something like mysql 'CREATE DATABASE dbname;' all in one line.
mysql --help | grep "\-execute"
Output:
-e, --execute=name Execute command and quit
So to create a database with command line client, you just need to execute
mysql -uuser -p -e"CREATE DATABASE dbname"
You can also concatenate several SQL statements, e.g.
mysql -uuser -p -e"CREATE DATABASE dbname;SHOW DATABASES"
Put the commands that you want executed into a text file (optionally with a file extension of .sql) then, from the command line, do mysql -uuser -p < yourtextfile.sql to have all of the commands in the file executed.
I have a MySQL DB that is the backend for my drupal web site, I am going through the drupal upgrade and before I do the upgrade I need to make a copy of the database.
mysqladmin create ts_prod_bak -u root --password=XXXXXX && \
mysqldump -u root --password=XXXXXX ts_prod | mysql -u root --password=XXXXXX -h localhost ts_prod_bak
This does create a new DB called ts_prod_bak and fills that DB with data from ts_prod but it isn't copying all of the data. I see some tables, cache_* that are created in the new DB but have a different size than the source. Because of this I am not confident in my backup/copy.
How can I make an exact duplicate of my source database and verify that by restoring it to another DB?
I want to copy my heroku production db (postgres) to my development (sqlite).
Copying a postgres db into another postgres db is easy using heroku pg:pull. Does anyone know how to use this command to copy postgres into sqlite?
Heroku docs on pg:pull do not say how to use different types of dbs. This old article implied that it used to be possible. Setting up a local postgres db is something I'd like to avoid.
You will need do a pg_restore locally then dump the data using the -a option to dump data only.
It should look something like this:
Download a data dump.
heroku addons:add pgbackups
heroku pgbackups:capture
curl -o latest.dump `heroku pgbackups:url`
Create a temporary database.
sudo -u postgres createdb tempdb
Restore the dump to your temporary database.
sudo -u postgres pg_restore --verbose --clean --no-acl --no-owner -h localhost -d tempdb latest.dump
Dump the data in the correct format.
sudo -u postgres pg_dump --inserts -a -b tempdb > data.sql
Read dump in sqlite3.
sqlite3
> .read data.sql
This is an approximate solution. You will most likely need to make some small adjustments.
I agree with Craig Ringer that it might be worth getting postgres running locally. Hopefully this process will do the trick though!
I try to copy postgresql table in another database as I write in pgAdmin 3 this query
$pg_dump -t pl_biz_enhanced business_catalog | psql business_catalog_enhanced
here pl_biz_enhanced is the table i want to copy and business_catalog is the database in which is this table
But I receive syntax error near $.
That's not an SQL query.
$pg_dump -t pl_biz_enhanced business_catalog | psql business_catalog_enhanced
The $ is a reference to the UNIX shell prompt, which usually ends in $.
This is a shell command. You can't run it in PgAdmin-III.
As far as I know there's no equivalent feature in PgAdmin-III. Either do the pg_dump | pg_restore in the command prompt or manually do the equivalent in PgAdmin-III, which would be to dump just the pl_biz_enhanced table of business_catalog and then restore it to the separate database business_catalog_enhanced.
I just finished my website here I used ASP.net & MySQL.
I uploaded my website file all right.
But the problem is with my database. I create my database very will and I create all my tables but the problem is that I can't execute my stored procedure?
That is because i don't have the privileges to do this operation?
The error in phpMyAdmin is:
MySQL said:
#1227 - Access denied; you need the SUPER privilege for this operation
How can I fix this?
As MySQL root:
$ mysql -u root -p # ..or, if no password has been set..
$ mysql -u root
Run this command:
GRANT SUPER ON *.* TO user#localhost;
