I am using MySQL Workbench 5.2.28 for designing my database schema. I need to insert default data into some tables which can be done using the "Inserts" tab. However, it seems like it only allows entering data manually, one row at a time. I have an OUTFILE with several hundred rows that I would like to insert.
Is this possible with MySQL Workbench? Would creating separate MySQL scripts for importing default data be a better approach?
I am now using separate sql scripts for inserting my data as there doesn't seem to be an easy way to add bulk inserts to MySQL workbench.
Generate CSV (quoted if you have comas in values) in Excel for example, then just copy/paste all rows into workbench via 'inserts' tab for each table in model.
Works with Workbench version 5.2.40.
In the MySQL Workbench Version 6.2 you will find a Import Button which alows you to Import Inserts from a CSV File with "," as delemiter.
You are right there is no way I know doing this automatically. The only thing you can do is to generate all your inserts scripts in a single time by doing a forward engeniering and then by copying the insert statements at the end of the generated script (You must check the option "Generate INSERT statements").

I have a .sql file from Oracle which contains create table/index statements and a lot of insert statements(around 1M insert).
I can manually modify the create table/index part(not too much), but for the insert part there are some Oracle functions like to_date.
I know MySql has a similar function STR_TO_DATE but the usage of the parameter is different.
I can connect to MySQL, but the .sql file is the only thing I got from Oracle.
Is there any way I can import this Oracle .sql file into MySQL?
Thanks.
Although the above job can be done by manually editing the script appropriately however there are products available which can be of use. Refer to the link for more information on one such product.
P.S. I am not affiliated in any way to the product
Since you mention about insert script basically i think you will be inserting data for this you can use any ETL tool, like open source tool like Pentaho data integrator, pretty simple to do, just search table to table transformation from different database connection on youtube to learn you should be able to connect to both mysql and oracle database else this wont help, but all the table structures you should create manually in the source database for data - you can just load it using ETL, no need to edit for every single line of insert if its more than 100 may be its very painful thing to do.
i've a MSSQL database and trying to migrate to MySQL database.. the problem is when I using MySQL WorkBench, some table records in my MSSQL database is not migrated (there is an error and MySQL Workbench not responding).. is there any tools to export MSSQL table records into SQL file that compatible to be executed in MySQL?
Both T-SQL and MySQL and support VALUES clause. So, right click on the database and select Generate scripts from Tasks:
Then you can choose objects:
and then make sure you have selected to get the data, too:
You can even get the schema and change it a little bit to match the MySQL syntax.
For small amount of data this is pretty cool. If you are exporting large tables it will be better to use another tool. For example, using bcp you can export your data in CSV format and then import it in the MySQL database.
I'm receiving a MySQL dump file .sql daily from an external server, which I don't have any control of. I created a local database to store all data in the .sql file. I hope I can set up a script to automatically update my local database daily. The sql file I'm receiving daily contains old data that is in the local database already. How can I avoid duplicates of such old data and only insert into the local MySQL server new data? Thank you very much!
You can use a third-party database compare tool such as those from Red Gate to create two databases, one current (your "master") and the new dump. You can then run the compare tool between the two versions and update only changes between them, updating your master.
Use unique constraints on field, that you want to be unique.
Also, as Danny Beckett mentioned, to avoid errors in output (which I would prefer to redirect into file for future analysis, to check, if I haven't missed anything in process), you can use INSERT IGNORE construct instead of INSERT.
You can use a constraint supported with IGNORE statement.
The second option, you can first insert the data to a temp table. Then insert only the difference.
Using the second option you may use some restriction to do not search for duplication through add records stored in database.
You need to create a primary key in your table. It should be a unique combination of column values. Using the INSERT query with IGNORE will avoid adding duplicates in this table.
see http://dev.mysql.com/doc/refman/5.5/en/insert.html
If this is a plain vanilla mysqldump file, then normally it includes DROP TABLE IF EXISTS... statements and create table statements, so the tables are recreated when the data is imported. So duplicte data should not be a problem, unless I'm missing something.
Was wondering if anyone had any insight or recommended tools for exporting the records from a PostgreSQL database and importing them into a MySQL database. I believe the table structure is 100% identical.
Thoughts? Thanks!
The command
pg_dump --data-only --column-inserts <database_name>
will generate SQL-standard-compliant INSERT statements with all column names listed and one VALUES clause per INSERT. This is the most portable way of moving data from PostgreSQL to any other SQL database.
Check out SquirrelSQL, it can pump data from one database brand into another via the DBCopy plugin. When the table structures are really identical it works quite well.
There is a ruby app called Taps that will do it. I've used it before with great success:

If I have a MySQL database with several tables on a live server, now I would like to migrate this database to another server. Of course, the migration I mean here involves some database tables, for example: add some new columns to several tables, add some new tables etc..
Now, the only method I can think of is to use some php/python(two scripts I know) script, connect two databases, dump the data from the old database, and then write into the new database. However, this method is not efficient at all. For example: in old database, table A has 28 columns; in new database, table A has 29 columns, but the extra column will have default value 0 for all the old rows. My script still needs to dump the data row by row and insert each row into the new database.
Using MySQLDump etc.. won't work. Here is the detail. For example: I have FOUR old databases, I can name them as 'DB_a', 'DB_b', 'DB_c', 'DB_d'. Now the old table A has 28 columns, I want to add each row in table A into the new database with a new column ID 'DB_x' (x to indicate which database it comes from). If I can't differentiate the database ID by the row's content, the only way I can identify them is going through some user input parameters.
Is there any tools or a better method than writing a script yourself? Here, I dont need to worry about multithread writing problems etc.., I mean the old database will be down (not open to public usage etc.., only for upgrade ) for a while.
Thanks!!
I don't entirely understand your situation with the columns (wouldn't it be more sensible to add any new columns after migration?), but one of the arguably fastest methods to copy a database across servers is mysqlhotcopy. It can copy myISAM only and has a number of other requirements, but it's awfully fast because it skips the create dump / import dump step completely.
Generally when you migrate a database to new servers, you don't apply a bunch of schema changes at the same time, for the reasons that you're running into right now.
MySQL has a dump tool called mysqldump that can be used to easily take a snapshot/backup of a database. The snapshot can then be copied to a new server and installed.
You should figure out all the changes that have been done to your "new" database, and write out a script of all the SQL commands needed to "upgrade" the old database to the new version that you're using (e.g. ALTER TABLE a ADD COLUMN x, etc). After you're sure it's working, take a dump of the old one, copy it over, install it, and then apply your change script.
Use mysqldump to dump the data, then echo output.txt > msyql. Now the old data is on the new server. Manipulate as necessary.
Sure there are tools that can help you achieving what you're trying to do. Mysqldump is a premier example of such tools. Just take a glance here:
http://dev.mysql.com/doc/refman/5.1/en/mysqldump.html
What you could do is:
1) You make a dump of the current db, using mysqldump (with the --no-data option) to fetch the schema only
2) You alter the schema you have dumped, adding new columns
3) You create your new schema (mysql < dump.sql - just google for mysql backup restore for more help on the syntax)
4) Dump your data using the mysqldump complete-insert option (see link above)
5) Import your data, using mysql < data.sql
This should do the job for you, good luck!
Adding extra rows can be done on a live database:
ALTER TABLE [table-name] ADD [row-name] MEDIUMINT(8) default 0;
MySql will default all existing rows to the default value.
So here is what I would do:
make a copy of you're old database with MySql dump command.
run the resulting SQL file against you're new database, now you have an exact copy.
write a migration.sql file that will modify you're database with modify table commands and for complex conversions some temporary MySql procedures.
test you're script (when fail, go to (2)).
If all OK, then goto (1) and go live with you're new database.
These are all valid approaches, but I believe you want to write a sql statement that writes other insert statements that support the new columns you have.
