↓ 04 – Execute Query | Windows | Linux
Execute Query is an operating system independent database utility written entirely in Java. Using the flexibility provided by Java Database Connectivity (JDBC), Execute Query provides a simple way to interact with almost any database from simple queries to table creation and import/export of an entire schema’s data.
The Query Editor allows for the execution of any SQL statement(s) that the database and driver may accept from creating tables to basic SELECT statements and table updates. The results of any executed statement is displayed in the results pane including database specific messages and error codes.
- Generate ERD: Allows for the creation of a database ERD either from scratch or from an existing schema. The diagram may be manipulated and saved in multiple image formats.
- Compare Data Types: Compares data types across different database connections providing useful mapping when porting a schema across different database types.
- Create Table: Allows for the creation of database tables via a graphical interface.
- Create Index: Allows for the creation of an index on a table via a graphical interface.
- Generate Scripts: This feature allows you to generate complete CREATE TABLE scripts for the connected schema including all table constraints.
- Import/Export Data: Allows for the import and export of data to and from delimited files.
- Import/Export XML Data: Allows for the import and export of data from one or multiple tables to and from XML files. The table and column names provide the XML tags.
