"How To" Guides for MySQL

Start the Derby Interactive SQL Tool

                        java -cp "c:\jdk1.6.0_01\db\lib\derby.jar;c:\jdk1.6.0_01\db\lib\derbytools.jar" org.apache.derby.tools.ij
                        

                        ​ij version 10.2
                  
                        

                        ​ij>

Show available commands

                        ​ij> help;

Connection commands

Create a database:

                        ​ij> connect 'jdbc:derby:C:/Documents and Settings/username/.derby/dbname;create=true';

To drop a database, simply remove the directory:

                        rmdir /s "%USERPROFILE%\.derby\dbname"

Connect to an existing database:

                        ​ij> connect 'jdbc:derby:C:/Documents and Settings/username/.derby/dbname';
                        

                        ​ij> connect 'jdbc:derby:C:/Documents and Settings/username/.derby/dbname' as connname;

The default connection name is "CONNECTIONn", where n is numeric.

Show information about established connections:

                        ​ij> show connections;

Switch to a different connection:

                        ​ij> set connname;

Disconnect a connection:

                        ​ij> disconnect current;
                        

                        ​ij> disconnect connname;

Schema commands

Create a schema

                        ​ij> create schema schemaname;
                        

                        ​ij> create schema "SchemaName";

Show available schemas

                        ​ij> show schemas;

Change schemas

                        ​ij> set current sqlid schemaname;
                        

                        ​ij> set current sqlid = "SchemaName";

Commands for Tables in Database

Show tables in schema

                        ​ij> show tables in sys;
                        

                        ​ij> show tables in schemaname;
                        

                        ​ij> show tables in "SchemaName";

Similarly, "views", "procedures" "synonyms" and "indexes" can also be displayed.

Show indexes for a table

                        ​ij> show indexes from tablename;
                        

                        ​ij> show indexes from schemaname.tablename;
                        

                        ​ij> show indexes from "SchemaName"."TableName";
