I have a table in a postgreSQL database that I would like to convert into a MySQL table. What would be the easiest way to do this? Any tools to do this? Remember, I am not converting the whole database to MySQL... I am just taking a table from that postgreSQL and convert it to MySQL table
You can use pg_dump to create a SQL dump from a single table and use this dump as input for mysql. Take a look at the option --data-only when you already have the tablestructure in your MySQL database and --column-inserts to create straight forward INSERT statements.
An ETL tool like SSIS, Pentaho, Talend or several others will do the trick. Most support a wide variety of data sources and destinations.

I would like to know how I can move date from Hive to MySQL?
I have seen example on how to move hive data to Amazon DynamoDB but not for a RDBMS like MySQL. Here is the example that I saw with DynamoDB:
CREATE EXTERNAL TABLE tbl1 ( name string, location string )
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES ("dynamodb.table.name" = "table",
"dynamodb.column.mapping" = "name:name,location:location") ;
I would like to do the same but with MySQL instead. I wonder if I need to code my own StorageHandler? I also to do not want to use sqoop. I want to be able to do my query directly in my HiveQL script.
You'd currently need a JDBC StorageHandler, which one has not been created just yet, but you could certain build your own.
There is currently an issue report for this which you can follow here:
https://issues.apache.org/jira/browse/HIVE-1555
Have you tried using Sqoop?. Its a good tool to do such kind of stuff.
There are many options. You can download the files in hive as csv file and then try bulk insert into mysql tables. You can use Sqoop. Or you can use some of the popular ETL tools like
Pentaho and many others.
I have 2 active database connections, I need to replace a number of tables from 'connection1' with that of connection2. The structures may, or may not be same, (depending if we make changes to the connection1 table.
I would assume I should do a complete table dump and replace keys where neccesary, but I really have no idea how to do this :)
Any help?
Have a look at Schema and Data sync tools in dbForge Studio for MySQL. It will help you to compare two databases on different servers, map tables and fields, generate and run synchronization script.
I ended up using the build in system command in PHP and mysqldump to first dump the data (export) to a file, then used system() again with mysql to import it into the new table and replace the old one.
Works like a charm :)
I was wondering if anybody had any advice or references that explain how to pull data from MySQL and drop it into SQLSever! Any input would be greatly appreciated!! Thanks!
You can add MySQL as a "linked server"

Once you did that you can reference the MySQL tables, views, etc with their fully qualified name in regular SQL Server queries
I could not tell if you wanted to access a MySQL database because you were migrating to SQL server, or if you wanted to access a MySQL database on an ongoing basis. I am answering as if you want to migrate, because you already have an excellent answer on accessing MySQL from SQL Server.
If you want to migrate, mysqldump is one way to go. Its format is easily parsed.
You can also write the results of any MySQL table -- and SQL Server for that matter -- to .csv format. .csv format is nearly a universal transfer format for data.
Hello is there any method to transfer the table layout and data from a Postgres database to MySQL automatic?
I have to migrate the scheme anda data to MYSQL
The easiest would probably be to export the database (schema & data) as SQL using Postgres' pg_dump utility, then import the resulting SQL file into MySql.
It's possible that there will be some incompatibilities in the intermediate SQL, but you can almost assuredly take care of these with a find/replace in your favorite text editor.
It is possible to do using the "Data Transfer" feature of Navicat Premium. It will not preserve foreign keys though, but the data transfers correctly with the two databases incompatibility issues resolved.
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:
