Utility to dump schema and data from a RDBMS. Features:

• Does schema-dumping, using (mainly) standard java API, by way of java.sql.DatabaseMetaData
• Does data-dumping (formats: csv, xml, html, json, sql 'insert into', sql 'update by PK', fixed column size, blob)
• Can be used with any JDBC-compliant databases
• Generates Entity-Relationship diagrams based on Tables and FKs (graphML output - yEd recommended)
• Flexible schema output patterns (based on schema name, object type and object name)
• Translation of metadata (column types) between different RDBMS dialects/implementations (partial)

SQLDump also has three subprojects:

• SQLRun: runs SQL scripts from files - may be used for regenerating database from dumped SQL-scripts. See sqlrun.template.properties for more info
• SQLDiff: generates a diff from 2 schema models. See sqldiff.template.properties for more info
• SQLMigrate: tool for schema migration. See sqlmigrate/README.md and sqlmigrate.template.properties for more info
• Diff2Queries: generates data diff from 2 SQL queries. See diff2q.template.properties for more info

SQLDump processing consists of:

1. 1 Grabber (implementation of SchemaModelGrabber, grabs a SchemaModel)
2. 'n' Processors (implementation of Processor, usually uses a Connection or SchemaModel) & Dumpers (implementation of SchemaModelDumper, dumps a SchemaModel)

Grabber can be:

• JDBCSchemaGrabber - Grabs schema metadata from a JDBC connection
• JAXBSchemaXMLSerializer - Grabs schema metadata from a XML file
• JSONSchemaSerializer - Grabs schema metadata from a JSON file

Processors can be:

• DataDump - Dumps data based on grabbed schema (can partition data from 1 table in different files, can dump in different formats)
• SQLQueries - Dumps data based on SQL-queries (same as DataDump - for each query)
• CascadingDataDump - Dumps data based on table relationships (FKs), given initial tables/filters
• graph.ResultSet2GraphML - Dumps a graphML diagram based on a SQL-query
• SQLDialectTransformer - Transforms schema models between different sql-dialects
• SQLRunProcessor - Loads properties into SQLRun and execute statements & importers
• mondrianschema.Olap4jMDXQueries - Dumps data from olap4j/mondrian engine
• mondrianschema.MondrianSchema2GraphProcessor - Dumps a graphML diagram based on a Mondrian Schema file
• mondrianschema.MondrianSchemaValidator - Validates a mondrian schema
• xtraproc.StatsProc - Grabs statistics from database

Dumpers can be:

• SchemaModelScriptDumper - Dumps schema model in SQL-script format (DDL)
• JAXBSchemaXMLSerializer - Dumps a XML representation of the schema model
• JSONSchemaSerializer - Dumps a JSON representation of the schema model
• graph.Schema2GraphML - Generates a Entity-Relationship diagram based on schema model
• mondrianschema.MondrianSchemaDumper - Generates a Star/Snowflake Mondrian Schema based on schema model
• xtradumpers.AlterSchemaSuggester - Generates suggestions of SQL-scripts for altering the schema model (beta)
• xtradumpers.DropScriptDumper - Generates drop SQL-scripts

All processing is controlled by a properties file. See sqldump.template.properties for more info.

Usage examples can be found at doc/examples.

• java 7 or newer
• apache-commons-logging
• log4j - optional but recommended
• database-dependent JDBC jars ( e.g. PostgreSQL, MySQL, Oracle, Derby, HSQLDB, H2, SQLite, MariaDB, Drizzle, MonetDB, Firebird, Virtuoso, jTDS/SQLServer, Neo4j )
• kmlutils - optional, for graphML output
• jettison - optional, for JSON output
• olap4j & mondrian - optional, for Mondrian Schema output, validation & data dump
• ant - recommended for building
• ivy - recommended for building

• Run git clone https://github.com/tbrugz/sqldump <project-dir> (if not done already)
