Table creation/Postal addresses
You are encouraged to solve this task according to the task description, using any language you may know.
In this task, the goal is to create a table to store addresses. You may assume that all the addresses to be stored will be located in the USA.
For non-database languages, show how you would open a connection to a database (your choice of which) and create an address table in it. You should follow the existing models here for how you would structure the table.
ALGOL 68
<lang algol68>MODE ADDRESS = STRUCT( INT page, FLEX[50]CHAR street, FLEX[25]CHAR city, FLEX[2]CHAR state, FLEX[10]CHAR zip ); FORMAT address repr = $"Page: "gl"Street: "gl"City: "gl"State: "gl"Zip: "gll$;
INT errno; FILE sequence; errno := open(sequence, "sequence.txt", stand back channel); SEMA sequence sema := LEVEL 1;
OP NEXTVAL = ([]CHAR table name)INT: (
INT out;
# INT table page = 0; # # only one sequence implemented #
# DOWN sequence sema; # # NO interprocess concurrency protection #
on open error(sequence,
(REF FILE f)BOOL: (
reset(sequence); #set(table page,1,1);#
put(sequence, 0);
try again;
FALSE
)
);
try again:
reset(sequence); #set(table page,1,1);# get(sequence,out);
out +:=1;
reset(sequence); #set(table page,1,1);# put(sequence,out);
# UP sequence sema; #
out
);
OP INIT = (REF ADDRESS self)REF ADDRESS: ( page OF self := NEXTVAL "address"; self);
REF ADDRESS john brown = INIT LOC ADDRESS;
john brown := (page OF john brown, "10 Downing Street","London","England","SW1A 2AA");
printf((address repr, john brown));
FILE address table; errno := open(address table,"address.txt",stand back channel);
- set(address table, page OF john brown,1,1); - standard set page not available in a68g #
put bin(address table, john brown); close(address table)</lang> Output:
Page: +1 Street: 10 Downing Strreet City: London State: England Zip: SW1A 2AA
C

DB2 UDB
<lang sql>CREATE TABLE Address ( addrID Integer generated by default as identity, addrStreet Varchar(50) not null, addrCity Varchar(25) not null, addrState Char(2) not null, addrZIP Char(10) not null )</lang>
J
J is a programming language, not a database, but it ships with a database built in the programming language called JDB. Using that, assuming hd is your database, then:
<lang j>
Create__hd 'Address';noun define
addrID autoid; addrStreet varchar addrCity varchar addrState char addrZip char ) </lang>
Of course J can connect external databases too, using e.g. ODBC. See the list of J database topics.
MySQL
<lang mysql>CREATE TABLE `Address` (
`addrID` int(11) NOT NULL auto_increment, `addrStreet` varchar(50) NOT NULL default , `addrCity` varchar(25) NOT NULL default , `addrState` char(2) NOT NULL default , `addrZIP` char(10) NOT NULL default , PRIMARY KEY (`addrID`)
);</lang>
Transact-SQL (MSSQL)
<lang sql>CREATE TABLE #Address (
addrID int NOT NULL Identity(1,1) PRIMARY KEY, addrStreet varchar(50) NOT NULL , addrCity varchar(25) NOT NULL , addrState char(2) NOT NULL , addrZIP char(10) NOT NULL
) drop table #Address</lang>
Oracle
<lang sql>CREATE SEQUENCE seq_address_pk START BY 100 INCREMENT BY 1 / CREATE TABLE address (
addrID NUMBER DEFAULT seq_address_pk.nextval, street VARCHAR2( 50 ) NOT NULL, city VARCHAR2( 25 ) NOT NULL, state VARCHAR2( 2 ) NOT NULL, zip VARCHAR2( 20 ) NOT NULL, CONSTRAINT address_pk1 PRIMARY KEY ( addrID )
) /</lang>
Oz
The SQLite version that comes with Ozsqlite does not understand "AUTOINCREMENT". <lang oz>declare
[Sqlite] = {Module.link ['x-ozlib:/sqlite/Sqlite.ozf']}
DB = {Sqlite.open 'test.db'}
in
try
{Sqlite.exec DB
"CREATE TABLE address ("
#"addrID INTEGER PRIMARY KEY,"
#"addrStreet TEXT NOT NULL,"
#"addrCity TEXT NOT NULL,"
#"addrState TEXT NOT NULL,"
#"addrZIP TEXT NOT NULL"
#")" _}
catch E then
{Inspector.configure widgetShowStrings true}
{Inspect E}
finally
{Sqlite.close DB}
end</lang>
Perl
<lang perl>use DBI;
my $db = DBI->connect('DBI:mysql:database:server','login','password');
my $statment = <<EOF; CREATE TABLE `Address` (
`addrID` int(11) NOT NULL auto_increment, `addrStreet` varchar(50) NOT NULL default , `addrCity` varchar(25) NOT NULL default , `addrState` char(2) NOT NULL default , `addrZIP` char(10) NOT NULL default , PRIMARY KEY (`addrID`)
); EOF
my $exec = $db->prepare($statment); $exec->execute;</lang>
This example uses mysql, but DBI supports a extensive list of database drivers. See dbi.perl.org for more info.
