Is there a way for me to see the insert statements that were used in a SQL table I created. I have provided a picture of the table. I just want to see the statements used to insert these values.
Adding to #Arihant answer,
go to
xampp folder
open cmd there
then
cd mysql
cd bin
then run command given by #Arihant
mysqldump <databasename> <tablename> > dbdump.sql
in same path xampp/mysql/bin you will find a file of name dbdump.sql having all create and insert statements

Is there any way to create multiple databases in a single line of a query?
Something like this:
$sql="CREATE DATABASE `db1` AND/,/./etc `db2` AND/,/./etc `db3`";
$mysql_query=($sql,$con);
Other options would be to create a SQL file such as:
/*myFile.sql*/
CREATE DATABASE db1;
CREATE DATABASE db2;
Then run:
mysql -u user -p < myFile.sql
If you absolutely have to have it on a single console line you could do:
mysql -u user -p -e "CREATE DATABASE db3; CREATE DATABASE db4; ..."
I am not sure, but it should work only separated by semicolon ;
You could try
mysqli_multi_query
but you have to been connected to database with mysqli_connect not mysql_connect :(
If PHPMyAdmin command or MySQL command -
CREATE DATABASE db01; CREATE DATABASE db02; CREATE DATABASE d03;CREATE DATABASE d04;
Create long script inside any text editor like notepad++, and copy, paste the Command in Console.
Then run command with
Ctrl + Enter
I know how to clone tables e.g.:
CREATE TABLE recipes_new LIKE production.recipes;
INSERT recipes_new
SELECT * FROM production.recipes;
But I don't know how to clone e.g. a database_old to database_new database with all the tables and rows from database_old.
So, only the name of the database will change. Everything else stays the same.
Right now I am cloning it by exporting the database in phpmyadmin ad then creating a new database and importing it to the new database.
But I guess there must be a more efficient way of doing this task via SQL query like that one for cloning tables.
IMPORTANT! It need to be done from SQL query window in phpmyadmin and not from a shell command line.
Thanks in advance for you suggestion how to do that.
have you tried using MySQL Dump?
$ mysqldump yourFirstDatabase -u user -ppassword > yourDatabase.sql
$ echo "create database yourSecondDatabase" | mysql -u user -ppassword
$ mysql yourSecondDatabase -u user -ppassword < yourDatabase.sql
IMPORTANT! It need to be done from SQL query window in phpmyadmin and not from a shell command line.
First create a blank database:
CREATE DATABASE `destination` DEFAULT CHARACTER SET
latin1 COLLATE latin1_swedish_ci;
Then use the command show tables;
show source.tables;
and then run the command for each DB table (Optimized Create table and inserting rows) as:
create table destination.table select * from source.table;
and other way is using like command:
create table destination.table like source.table
and then inserting rows;
insert into destination.table select * from source.table
If phpMyAdmin is available for the database, you can clone it by following these steps:
Select required database
Click on the operation tab
In the operation tab, go to the "copy database"-option and type your desired clone-db-name into the input field
Select "Structure and data" (Depends on your requirement)
Check the boxes, "CREATE DATABASE before copying" and "Add AUTO_INCREMENT value"
Click "GO"
Tested with phpMyAdmin 4.2.13.3
export your chosen database using phpmyadmin (export.sql)
import it using terminal/cmd:
mysql -u username -p databasename < export.sql
and get a cup of coffee...
I have a mysql dump created with mysqldump that holds all the tables in my database and all their data. However I only want to restore two tables. (lets call them kittens and kittens_votes)
How would I restore those two tables without restoring the entire database?
Well, you have three main options.
You can manually find the SQL statements in the file relating to the backed up tables and copy them manually. This has the advantage of being simple, but for large backups it's impractical.
Restore the database to a temporary database. Basically, create a new db, restore it to that db, and then copy the data from there to the old one. This will work well only if you're doing single database backups (If there's no CREATE DATABASE command(s) in the backup file).
Restore the database to a new database server, and copy from there. This works well if you take full server backups as opposed to single database backups.
Which one you choose will depend upon the exact situation (including how much data you have)...
You can parse out CREATE TABLE kittens|kitten_votes AND INSERT INTO ... using regexp, for example, and only execute these statements. As far as I know, there's no other way to "partially restore" from dump.
Open the .sql file and copy the insert statements for the tables you want.
create a new user with access to only those 2 tables. Now restore the DB with -f (force) option that will ignore the failed statements and execute only those statements it has permission to.
What you want is a "Single Table Restore"
http://hashmysql.org/wiki/Single_table_restore
A few options are outlined above ... However the one which worked for me was:
Create a new DB
$ mysql -u root -p CREATE DATABASE temp_db
Insert the .sql file ( the one with the desired table ) into the new DB
$ mysql -u root -p temp_db < ~/full/path/to/your_database_file.sql
dump the desired table
$ mysqldump -u root -p temp_db awesome_single_table > ~/awesome_single_table.sql
import desired table
$ mysql -u root -p original_database < ~/awesome_single_table.sql
Then delete the temp_db and you're all golden!
Is there any application that will read a MySQL database table and generate a SQL script of INSERT statements (so that I can copy tables from one db to another db)? OR how can I transfer content from db1.table1 to db2.table2 where table1 and table2 is same.
Thank you.
mysqldump [options] db_name [tbl_name ...]
Will generate the script file including the create and inserts necessary for the tables selected. To import the dump you can simply do:
mysql -u <user> -p dbname < mys.dmp
You should take a look at mysqldump. You can specify the --nodata option to export the schema only.
Hi I use mysql administrator and have restored backup files (backup.sql). I would like to use restore the structure without data and it is not giving me an option to do so. I understand phpadmin provides this. I can not use this however. Any one can tell me an easy way?
Dump database structure only:
cat backup.sql | grep -v ^INSERT | mysql -u $USER -p
This will execute everything in the backup.sql file except the INSERT lines that would have populated the tables. After running this you should have your full table structure along with any stored procedures / views / etc. that were in the original databse, but your tables will all be empty.
You can change the ENGINE to BLACKHOLE in the dump using sed
cat backup.sql | sed 's/ENGINE=(MYISAM|INNODB)/ENGINE=BLACKHOLE/g' > backup2.sql
This engine will just "swallow" the INSERT statements and the tables will remain empty. Of course you must change the ENGINE again using:
ALTER TABLE `mytable` ENGINE=MYISAM;
IIRC the backup.sql files (if created by mysqldump) are just SQL commands in a text file. Just copy-paste all the "create ..." statements from the beginning of the file, but not the "insert" statements in to another file and "mysql < newfile" you should have the empty database without any data in it.
there is no way to tell the mysql client to skip the INSERT commands. the least-hassle way to do this is run the script as-is and let it load the data, then just TRUNCATE all of the tables.
you can write a script to do the following:
1 : import the dump into a new database.
2 : truncate all the tables with a loop.
3 : export the db again.
4 : now u just have the structure
You can backup you MYSQL database structure with
mysqldump -u username –p -d database_name > backup.sql
(You should not supply password at command line as it leads to security risks.MYSQL will ask for password by default.)
