Description
Connects to the database indicated by
the ConnectionURLString. Specifically, takes the value of the string (the
database connection URL) and issues a getConnection request using java.sql.DriverManager or a javax.sql.DataSource implementation (see the ij.dataSource property)
to set the current connection to that database connection URL.
You have
the option of specifying a name for your connection. Use the Set
Connection command to switch between connections. If you do not name
a connection, the system generates a name automatically.
You also have
the option of specifying a named protocol previously created with the Protocol command
or the ij.protocol.protocolName property.
If
the connection requires a user name and password, supply those with the optional
user and password parameters.
If the connect succeeds, the connection
becomes the current one and ij displays a new prompt for the next command
to be entered. If you have more than one open connection, the name of the
connection appears in the prompt.
All further commands are processed
against the new, current connection.
Examples
ij> connect 'jdbc:derby:menuDB;create=true';
ij> -- we create a new table in menuDB:
CREATE TABLE menu(course CHAR(10), item CHAR(20), price INTEGER);
ij> protocol 'jdbc:derby:';
ij> connect 'sample' as sample1;
ij(SAMPLE1)> connect 'newDB;create=true' as newDB;
ij(NEWDB)> show connections;
CONNECTION0 - jdbc:derby:menuDB
NEWDB* - jdbc:derby:anotherDB
SAMPLE1 - jdbc:derby:newDB

ij> connect 'jdbc:derby:sample' user 'sa' password 'cloud3x9';
