SQL Workbench/J是一个独立于DBMS，跨平台的SQL查询分析工具。支持：直接在查询结果集中编辑，新增和删除数据；在查询结果集、SQL statement、导入和导出中支持BLOB数据。在SQL语句中采用变量替换；能够生成数据结构的XML报告，以便能够重构数据库模型；能够比较两个 数据库在结构上有何不同之处；在编辑SQL语句时能够自动提示表格和字段；所有SQL脚本运行在批处理模式下；SQL Workbench/J还提供一个DataPumper工具用于直接在两台服务器上相互复制数据，DataPumper功能还能够当作SQL命令使用以实 现批处理。

• Display result data from SQL queries (Screenshot)
• Edit, insert and delete data directly in the result table (Screenshot)
• Powerful export command to write text files (aka "CSV"), XML, HTML or SQL (including BLOB data).
  All user tables can be exported into a directory with a single command. Export files can be compress "on-the-fly".
• Powerful text and XML file import. A set of files (including compressed files) can be imported from a directory with a single command. Foreign key constraints are detected to insert the data in the correct order
• Compare two database schemas for differences. The XML output can be transformed into the approriate SQL ALTER statements using XSLT
• Compare the data of two database and generate the necessary SQL statements to migrate one to the other.
• Reformatting (Pretty-Print) of SQL Statements (Screenshot)
• Full support for BLOB data in query results, SQL statements, export and import. Read more...
• Select rows from related tables according to their foreign key definitions (Screenshot1 Screenshot2).
  
• Search text in procedure, view and other sources using a SQL command or a GUI (Screenshot)
• Search for data across all columns in all tables using a SQL command or a GUI (Screenshot)
• Copy data directly between to database servers using a SQL command or a GUI (Screenshot)
• Macros (aka aliases) for frequently used SQL statements
• Variable substitution in SQL statements including smart prompting for values (can be combined with macros)
• Auto completion for tables and columns in SQL statements (Screenshot)
• Tooltips for INSERT statements to show the corresponding value or column (Screenshot)
• All SQL Scripts (including Workbench specific commands) can be run in batch mode
• An interactive console mode (Screenshot)
• Display table, view and procedure definitions (Screenshot)
