mysqldumpsplitter - MySQL Dump splitter to split / extract databases, tables, list from mysqldump with plenty of more funtionality.

Usage:

Download the utility from website or git repository.


************ Usage ************

sh mysqldumpsplitter.sh --source filename --desc --extract [DB|TABLE|DBTABLES|ALLDBS|ALLTABLES|REGEXP] --match_str string --compression [gzip|pigz|bzip2|none] --decompression [gzip|pigz|bzip2|none] --output_dir [path to output dir] [--config /path/to/config]

Options:

--source: mysqldump filename to process. It could be a compressed or regular file.
--desc: This option will list out all databases and tables.
--extract: Specify what to extract. Possible values DB, TABLE, ALLDBS, ALLTABLES, REGEXP
--match_str: Specify match string for extract command option.
--compression: gzip/pigz/bzip2/none (default: gzip). Extracted file will be of this compression.
--decompression: gzip/pigz/bzip2/none (default: gzip). This will be used against input file.
--output_dir: path to output dir. (default: ./out/)
--config: path to config file. You may use --config option to specify the config file that includes following variables.
	SOURCE=
	EXTRACT=
	COMPRESSION=
	DECOMPRESSION=
	OUTPUT_DIR=
	MATCH_STR=

mysqldumpsplitter recipe:

  1. Extract single database from mysqldump:

sh mysqldumpsplitter.sh --source filename --extract DB --match_str database-name

Above command will create sql for specified database from specified "filename" sql file and store it in compressed format to database-name.sql.gz.

  1. Extract single table from mysqldump:

sh mysqldumpsplitter.sh --source filename --extract TABLE --match_str table-name

Above command will create sql for specified table from specified "filename" mysqldump file and store it in compressed format to database-name.sql.gz.

  1. Extract tables matching regular expression from mysqldump:

sh mysqldumpsplitter.sh --source filename --extract REGEXP --match_str regular-expression

Above command will create sqls for tables matching specified regular expression from specified "filename" mysqldump file and store it in compressed format to individual table-name.sql.gz.

  1. Extract all databases from mysqldump:

sh mysqldumpsplitter.sh --source filename --extract ALLDBS

Above command will extract all databases from specified "filename" mysqldump file and store it in compressed format to individual database-name.sql.gz.

  1. Extract all table from mysqldump:

sh mysqldumpsplitter.sh --source filename --extract ALLTABLES

Above command will extract all tables from specified "filename" mysqldump file and store it in compressed format to individual table-name.sql.gz.

  1. Extract list of tables from mysqldump:

sh mysqldumpsplitter.sh --source filename --extract REGEXP --match_str '(table1|table2|table3)'

Above command will extract tables from the specified "filename" mysqldump file and store them in compressed format to individual table-name.sql.gz.

  1. Extract a database from compressed mysqldump:

sh mysqldumpsplitter.sh --source filename.sql.gz --extract DB --match_str 'dbname' --decompression gzip

Above command will decompress filename.sql.gz using gzip, extract database named "dbname" from "filename.sql.gz" & store it as out/dbname.sql.gz

  1. Extract a database from compressed mysqldump in an uncompressed format:

sh mysqldumpsplitter.sh --source filename.sql.gz --extract DB --match_str 'dbname' --decompression gzip --compression none

Above command will decompress filename.sql.gz using gzip and extract database named "dbname" from "filename.sql.gz" & store it as plain sql out/dbname.sql

  1. Extract alltables from mysqldump in different folder:

sh mysqldumpsplitter.sh --source filename --extract ALLTABLES --output_dir /path/to/extracts/

Above command will extract all tables from specified "filename" mysqldump file and extracts tables in compressed format to individual files, table-name.sql.gz stored under /path/to/extracts/. The script will create the folder /path/to/extracts/ if not exists.

  1. Extract one or more tables from one database in a full-dump:

Consider you have a full dump with multiple databases and you want to extract few tables from one database.

Extract single database:
`sh mysqldumpsplitter.sh --source filename --extract DB --match_str DBNAME --compression none`

Extract all tables
`sh mysqldumpsplitter.sh --source out/DBNAME.sql --extract REGEXP --match_str "(tbl1|tbl2)"`

though we can use another option to do this in single command as follows:

sh mysqldumpsplitter.sh --source filename --extract DBTABLE --match_str "DBNAME.(tbl1|tbl2)" --compression none

Above command will extract both tbl1 and tbl2 from DBNAME database in sql format under folder "out" in current directory.

You can extract single table as follows:

sh mysqldumpsplitter.sh --source filename --extract DBTABLE --match_str "DBNAME.(tbl1)" --compression none

  1. Extract all tables from specific database:

mysqldumpsplitter.sh --source filename --extract DBTABLE --match_str "DBNAME.*" --compression none

Above command will extract all tables from DBNAME database in sql format and store it under "out" directory.

  1. List content of the mysqldump file

mysqldumpsplitter.sh --source filename --desc

Above command will list databases and tables from the dump file.

You can’t perform that action at this time.
