or die "Cannot connect: " . $DBI::errstr;
$sth = $dbh->prepare("CREATE TABLE a (id INTEGER, name CHAR(10))")
or die "Cannot prepare: " . $dbh->errstr();
$sth->execute() or die "Cannot execute: " . $sth->errstr();
$sth->finish();

=head1 DESCRIPTION
DBD::Sprite is a DBI extension module adding database emulation via flat-files
to Perl's database-independent database interface. Unlike other DBD::modules,
DBD::Sprite does not require you to purchase or obtain a database. Every
thing you need to prototype database-independent applications using Perl and
DBI are included here. You will, however, probably wish to obtain a real
database, such as "mysql", for your production and larger data needs. This
is because emulating databases and SQL with flat text files gets very slow as
the size of your "database" grows to a non-trivial size (a few dozen records
or so per table).
DBD::Sprite is built upon an old Perl module called "Sprite", written by
Shishir Gurdavaram. This code was used as a starting point. It was completly
reworked and many new features were added, producing a module called
"JSprite.pm" (Jim Turner's Sprite). This was then merged in to DBI::DBD to
produce what you are installing now. (DBD::Sprite). JSprite.pm is included
in this module as a separate file, and is required.
Many thanks go to Mr. Gurdavaram.
The main advantage of DBD::Sprite is the ability to develop and test
prototype applications on personal machines (or other machines which do not
have an Oracle licence or some other "mainstream" database) before releasing
them on "production" machines which do have a "real" database. This can all
be done with minimal or no changes to your Perl code.
Another advantage of DBD::Sprite is that you can use Perl's regular
expressions to search through your data. Maybe, someday, more "real"
databases will include this feature too!
DBD::Sprite provides the ability to emulate basic database tables
and SQL calls via flat-files. The primary use envisioned
for this to permit website developers who can not afford
to purchase an Oracle licence to prototype and develop Perl
applications on their own equipment for later hosting at
larger customer sites where Oracle is used. :-)
DBD::Sprite attempts to do things in as database-independent manner as possible,
but where differences occurr, JSprite most closely emmulates Oracle, for
example "sequences/autonumbering". JSprite uses tiny one-line text files
called "sequence files" (.seq). and "seq_file_name.NEXTVAL" function to
insert into autonumbered fields. The reason for this is that the Author
works in an Oracle shop and wrote this module to allow himself to work on
code on his PC, and machines which did not have Oracle on them, since
obtaining Oracle licences was sometimes time-consuming.
DBD::Sprite is similar to DBD::CSV, but differs in the following ways:
1) It creates and works on true "databases" with user-ids and passwords,
real datatypes like numeric, varchar, blob, etc. with max. precisions and
scales.
2) The database author specifies the field delimiters, record delimiters,
user, password, table file path, AND extension for each database.
3) Transactions (commits and rollbacks) are fully supported!
4) Autonumbering and user-defined functions are supported.
5) You don't need any other modules or databases. (NO prerequisites
except Perl 5 and the DBI module!
6) Quotes are not used around data.
7) It is not necessary to call the "$dbh->quote()" method all the time
in your sql.
8) NULL is handled as an empty string.
9) Users can "register" their own data-conversion functions for use in
sql. See "fn_register" method below.
10) Optional data encryption.
11) Optional table storage in XML format.
12) Two-table joins now supported!
=head1 INSTALLATION
Installing this module (and the prerequisites from above) is quite
simple. You just fetch the archive, extract it with
gzip -cd DBD-Sprite-0.1000.tar.gz | tar xf -
(this is for Unix users, Windows users would prefer WinZip or something
similar) and then enter the following:
cd DBD-Sprite-#.###
perl Makefile.PL
make
make test
If any tests fail, let me know. Otherwise go on with
make install
Note that you almost definitely need root or administrator permissions.
If you don't have them, read the ExtUtils::MakeMaker man page for
details on installing in your own directories. the ExtUtils::MakeMaker
manpage.
NOTE: You may also need to copy "makesdb.pl" to /usr/local/bin or
somewhere in your path.
=head1 GETTING STARTED:
1) cd to where you wish to store your database.
2) run makesdb.pl to create your database, ie.
Database name: mydb
Database user: me
User password: mypassword
Database path: .
Table file extension (default .stb):
Record delimiter (default \n):
Field delimiter (default ::):
This will create a new database text file (mydb.sdb) in the current
directory. This ascii file contains the information you enterred
above. To add additional user-spaces, simply rerun makesdb.pl with
"mydb" as your database name, and enter additional users (name,
password, path, extension, and delimiters). For an example, after
running "make test", look at the file "test.sdb".
When connecting to a Sprite database, Sprite will look in the current
directory, then, if specified, the path in the SPRITE_HOME environment
variable.
The database name, user, and password are used in the "db->connect()"
method described below. The "database path" is where your tables will
be created and reside. Table files are ascii text files which will
have, by default, the extension ".stb" (Sprite table). By default,
each record will be written to a single line (separated by \n --
Windows users should probably use "\r\n"). Each field datum will be
written without quotes separated by the "field delimiter (default:
double-colon). The first line of the table file consists of the
a field name, an equal ("=") sign, an asterisk if it is a key field,
then the datatype and size. This information is included for each
field and separated by the field separator. For an example, after
running "make test", look at the file "testtable.stb".
3) write your script to use DBI, ie:
#!/usr/bin/perl
use DBI;
$dbh = DBI->connect('DBI:Sprite:mydb','me','mypassword') ||
die "Could not connect (".$DBI->err.':'.$DBI->errstr.")!";
...
#CREATE A TABLE, INSERT SOME RECORDS, HAVE SOME FUN!
4) get your application working.
5) rehost your application on a "production" machine and change "Sprite"
to a DBI driver for a "real" database!
=head1 CREATING AND DROPPING TABLES
You can create and drop tables with commands like the following:
$dbh->do("CREATE TABLE $table (id INTEGER, name CHAR(64))");
$dbh->do("DROP TABLE $table");
Column names, datatypes, precision, scales, and autonumber sequences are
stored on the top line as COLUNM_NAME(PRECISION[,SCALE])=DEFAULT_VALUE
A drop just removes the file without any warning.
See the DBI(3) manpage for more details.
Table names cannot be arbitrary, due to restrictions of the SQL syntax.
I recommend that table names are valid SQL identifiers: The first
character is alphabetic, followed by an arbitrary number of alphanumeric
characters. If you want to use other files, the file names must start
with '/', './' or '../' and they must not contain white space.
=head1 INSERTING, FETCHING AND MODIFYING DATA
The following examples insert some data in a table and fetch it back:
First all data in the string:
$dbh->do("INSERT INTO $table VALUES (1, 'foobar')");
Note the use of the quote method for escaping the word 'foobar'. Any
string must be escaped, even if it doesn't contain binary data.
Next an example using parameters:
$dbh->do("INSERT INTO $table VALUES (?, ?)", undef,
2, "It's a string!");
To retrieve data, you can use the following:
my($query) = "SELECT * FROM $table WHERE id > 1 ORDER BY id";
my($sth) = $dbh->prepare($query);
$sth->execute();
while (my $row = $sth->fetchrow_hashref) {
print("Found result row: id = ", $row->{'id'},
", name = ", $row->{'name'});
}
$sth->finish();
Again, column binding works: The same example again.
my($query) = "SELECT * FROM $table WHERE id > 1 ORDER BY id";
my($sth) = $dbh->prepare($query);
$sth->execute();
my($id, $name);
$sth->bind_columns(undef, \$id, \$name);
while ($sth->fetch) {
print("Found result row: id = $id, name = $name\n");
}
$sth->finish();
Of course you can even use input parameters. Here's the same example for
the third time:
my($query) = "SELECT * FROM $table WHERE id = ?";
my($sth) = $dbh->prepare($query);
$sth->bind_columns(undef, \$id, \$name);
for (my($i) = 1; $i <= 2; $i++) {
$sth->execute($id);
if ($sth->fetch) {
print("Found result row: id = $id, name = $name\n");
}
$sth->finish();
}
See the DBI(3) manpage for details on these methods. See the
SQL::Statement(3) manpage for details on the WHERE clause.
Data rows are modified with the UPDATE statement:
$dbh->do("UPDATE $table SET id = 3 WHERE id = 1");
Likewise you use the DELETE statement for removing rows:
$dbh->do("DELETE FROM $table WHERE id > 1");
I<fn_register>
Method takes 2 arguments: Function name and optionally, a
package name (default is "main").
$dbh->fn_register ('myfn','mypackage');
-or-
use JSprite;
JSprite::fn_register ('myfn',__PACKAGE__);
Then, you could say in sql:
insert into mytable values (myfn(?))
and bind some value to "?", which is passed to "myfn", and the return-value
is inserted into the database. You could also say (without binding):
insert into mytable values (myfn('mystring'))
-or (if the function takes a number)-
select field1, field2 from mytable where field3 = myfn(123)
I<Return Value>
None
=head1 ERROR HANDLING
In the above examples we have never cared about return codes. Of course,
this cannot be recommended. Instead we should have written (for
example):
my($query) = "SELECT * FROM $table WHERE id = ?";
my($sth) = $dbh->prepare($query)
or die "prepare: " . $dbh->errstr();
$sth->bind_columns(undef, \$id, \$name)
or die "bind_columns: " . $dbh->errstr();
for (my($i) = 1; $i <= 2; $i++) {
$sth->execute($id)
or die "execute: " . $dbh->errstr();
if ($sth->fetch) {
print("Found result row: id = $id, name = $name\n");
}
}
$sth->finish($id)
or die "finish: " . $dbh->errstr();
Obviously this is tedious. Fortunately we have DBI's *RaiseError*
attribute:
$dbh->{'RaiseError'} = 1;
$@ = '';
eval {
my($query) = "SELECT * FROM $table WHERE id = ?";
my($sth) = $dbh->prepare($query);
$sth->bind_columns(undef, \$id, \$name);
for (my($i) = 1; $i <= 2; $i++) {
$sth->execute($id);
if ($sth->fetch) {
print("Found result row: id = $id, name = $name\n");
}
}
$sth->finish($id);
};
if ($@) { die "SQL database error: $@"; }
This is not only shorter, it even works when using DBI methods within
subroutines.
=head1 METADATA
The following attributes are handled by DBI itself and not by DBD::File,
thus they should all work as expected: I have only used the last 3.
I<Active>
I<ActiveKids>
I<CachedKids>
I<CompatMode> (Not used)
I<InactiveDestroy>
I<Kids>
I<PrintError>
I<RaiseError>
I<Warn>
The following DBI attributes are handled by DBD::Sprite:
B<AutoCommit>
Works
B<ChopBlanks>
Should Work
B<NUM_OF_FIELDS>
Valid after `$sth->execute'
B<NUM_OF_PARAMS>
Valid after `$sth->prepare'
B<NAME>
Valid after `$sth->execute'; undef for Non-Select statements.
B<NULLABLE>
Not really working. Always returns an array ref of one's, as
DBD::Sprite always allows NULL (handled as an empty string).
Valid after `$sth->execute'.
B<PRECISION>
Works
B<SCALE>
Works
B<LongReadLen>
Should work
B<LongTruncOk>
Works
These attributes and methods are not supported:
B<bind_param_inout>
B<CursorName>
In addition to the DBI attributes, you can use the following dbh
attributes. These attributes are read-only after "connect".
I<sprite_dbdir>
Path to tables for database.
I<sprite_dbext>
File extension used on table files in the database.
I<sprite_dbuser>
Current database user.
I<sprite_dbfdelim>
Field delimiter string in use for the database.
I<sprite_dbrdelim>
Record delimiter string in use for the database.
The following are environment variables specifically recognized by Sprite.
I<SPRITE_HOME>
Environment variable specifying a path to search for Sprite
databases (*.sdb) files.
The following are Sprite-specific options which can be set when connecting.
I<sprite_CaseTableNames> => 0 | 1
By default, table names are case-insensitive (as they are in Oracle),
to make table names case-sensitive (as in MySql), so that one could
have two separate tables such as "test" and "TEST", set this option
to 1.
I<sprite_CaseFieldNames> => 0 | 1
By default, field names are case-insensitive (as they are in Oracle),
to make field names case-sensitive, so that one could
have two separate fields such as "test" and "TEST", set this option
to 1. The default is 1 (case-sensitive) if XML.
I<sprite_StrictCharComp> => 0 | 1
CHAR fields are always right-padded with spaces to fill out
the field. Old (pre 5.17) Sprite behaviour was to require the
padding be included in literals used for testing equality in
"where" clauses. I discovered that Oracle and some other databases
do not require this when testing DBIx-Recordset, so Sprite will
automatically right-pad literals when testing for equality.
To disable this and force the old behavior, set this option to 1.
I<sprite_Crypt> => [encrypt=|decrypt=][Crypt]::CBC;][[IDEA[_PP]|DES[_PP]|BLOWFISH[_PP];]keystring
Optional encryption and/or decryption of data stored in tables. By
omitting "encrypt=" and "decrypt=", data will be decrypted when read
from the table and encrypted when written to the table using the
"keystring" as the key.
I<sprite_forcereplace> => 0 | 1
This option forces the table file to first be deleted before being
overwritten. Default is 0 (do not delete, just overwrite it). This
was need by the author on certain network filesystems on one jobsite.
I<sprite_xsl> => xsl_stylesheet_url
Optional xsl stylesheet url to be included in database tables in XML
format. Otherwise, ignored. Default none.
I<silent> => 0 | 1
By default, on error, Sprite prints the legacy
"Oops! Sprite encountered the following error when processing your request..."
multiline error message carried over from the original Sprite by
Shishir Gurdavaram. Set to 1 to silense this, if it annoys you, or if you
are using Sprite in a CGI script.
The following attributes can be specified as a hash reference in "prepare"
statements:
I<sprite_reclimit> => #
Limit processing the table to # records. This is NOT the same as a
"LIMIT #" clause in selects. This limits the query to the first #
records in the table UNSORTED - BEFORE any constraints or sorting are
applied. This is useful for limiting queries to, say 1 record
simply to populate the column metadata.
I<sprite_actlimit> => #
This is the same as adding a "LIMIT #" clause to a select statement
when preparing it, as it will limit a query to returning # records
AFTER applying any constraints and sorting.
=head1 DRIVER PRIVATE METHODS
B<DBI>->B<data_sources>()
The `data_sources' method returns a list of "databases" (.sdb files)
found in the current directory and, if specified, the path in
the SPRITE_HOME environment variable.
$dbh->B<tables>()
This method returns a list of table names specified in the current
database.
Example:
my($dbh) = DBI->connect("DBI:Sprite:mydatabase",'me','mypswd');
my(@list) = $dbh->func('tables');
B<JSprite::fn_register>('myfn', __PACKAGE__);
This method takes the name of a user-defined data-conversion function
for use in SQL commands. Your function can optionally take arguments,
but should return a single number or string. Unless your function
is defined in package "main", you must also specify the package name
or "__PACKAGE__" for the current package. For an example, see the
section "INSERTING, FETCHING AND MODIFYING DATA" above or (JSprite(3)).
=head1 OTHER SUPPORTING UTILITIES
B<makesdb.pl>
This utility lets you build new Sprite databases and later add
additional user-spaces to them. Simply cd to the directory where
you wish to create / modify a database, and run. It prompts as
follows:
Database name: Enter a 1-word name for your database.
Database user: Enter a 1-word user-name.
User password: Enter a 1-word password for this user.
Database path: Enter a path (no trailing backslash) to store tables.
Table file extension (default .stb):
Record delimiter (default \n):
Field delimiter (default ::):
The last 6 prompts repeat until you do not enter another user-name
allowing you to set up multiple users in a single database. Each
"user" can have it's own separate tables by specifying different
paths, file-extensions, password, and delimiters! You can invoke
"makesdb.pl" on an existing database to add new users. You can
edit it with vi to remove users, delete the 5 lines starting with
the path for that user. The file is all text, except for the
password, which is encrypted for your protection!
=head1 RESTRICTIONS
Although DBD::Sprite supports the following datatypes:
NUMBER FLOAT DOUBLE INT INTEGER NUM CHAR VARCHAR VARCHAR2
DATE LONG BLOB and MEMO, there are really only 4 basic datatypes
(NUMBER, CHAR, VARCHAR, and BLOB). This is because Perl treates
everything as simple strings. The first 5 are all treated as "numbers"
by Perl for sorting purposes and the rest as strings. This is seen
when sorting, ie NUMERIC types sort as 1,5,10,40,200, whereas
STRING types sort these as 1,10,200,40,5. CHAR fields are right-
padded with spaces when stored. LONG-type fields are subject to
truncation by the "LongReadLen" attribute value.
DBD::Sprite works with the tieDBI module, if "Sprite => 1" lines are added
to the "%CAN_BIND" and "%CAN_BINDSELECT" hashes. This should not be
necessary, and I will investigate when I have time.
=head1 KNOWN BUGS
* The module is using flock() internally. However, this function is
not available on platforms. Using flock() is disabled on MacOS
and Windows 95: There's no locking at all (perhaps not so
important on these operating systems, as they are for single
users anyways).
