NAME

DBIx::Array - DBI Wrapper with Perl style data structure interfaces

SYNOPSIS

use DBIx::Array;
my $dbx   = DBIx::Array->new;
$dbx->connect($connection, $user, $pass, \%opt); #passed to DBI
my @array = $dbx->sqlarray($sql, @params);

With a connected database handle

use DBIx::Array;
my $dbx   = DBIx::Array->new(dbh=>$dbh);

With stored connection information from a File

use DBIx::Array::Connect;
my $dbx   = DBIx::Array::Connect->new(file=>"my.ini")->connect("mydatabase");

DESCRIPTION

This module provides a Perl data structure interface for Structured Query Language (SQL). This module is for people who truly understand SQL and who understand Perl data structures. If you understand how to modify your SQL to meet your data requirements then this module is for you.

This module is used to connect to Oracle 10g and 11g using DBD::Oracle on both Linux and Win32, MySQL 4 and 5 using DBD::mysql on Linux, Microsoft SQL Server using DBD::Sybase on Linux and using DBD::ODBC on Win32 systems, and PostgreSQL using DBD::Pg in a 24x7 production environment. Tests are written against DBD::CSV and DBD::XBase.

CONVENTIONS

USAGE

Loop through data

foreach my $row ($dbx->sqlarrayhash($sql, @bind)) {
  do_something($row->{"id"}, $row->{"column"});
}

Easily generate an HTML table

my $cgi  = CGI->new("");
my $html = $cgi->table($cgi->Tr([map {$cgi->td($_)} $dbx->sqlarrayarrayname($sql, @param)]));

Bless directly into a class

my ($object) = $dbx->sqlarrayobject("My::Package", $sql, {id=>$id}); #bless({id=>1, name=>'foo'}, 'My::Package');
my @objects  = $dbx->absarrayobject("My::Package", "myview", '*', {active=>1}, ["name"]); #($object, $object, ...)

CONSTRUCTOR

new

my $dbx = DBIx::Array->new();
$dbx->connect(...); #connect to database, sets and returns dbh

my $dbx = DBIx::Array->new(dbh=>$dbh); #already have a handle

initialize

METHODS (Properties)

dbh

Sets or returns the database handle object.

my $dbh = $dbx->dbh;
$dbx->dbh($dbh);  #if you already have a connection

name

Sets or returns a user friendly identification string for this database connection

my $name = $dbx->name;
$dbx->name($string);

METHODS (DBI Wrappers)

connect

Wrapper around DBI->connect; Connects to the database, sets dbh property, and returns the database handle.

$dbx->connect($connection, $user, $pass, \%opt); #sets $dbx->dbh
my $dbh = $dbx->connect($connection, $user, $pass, \%opt);

Examples:

$dbx->connect("DBI:mysql:database=mydb;host=myhost", "user", "pass", {AutoCommit=>1, RaiseError=>1});
$dbx->connect("DBI:Sybase:server=myhost;datasbase=mydb", "user", "pass", {AutoCommit=>1, RaiseError=>1}); #Microsoft SQL Server API is same as Sybase API
$dbx->connect("DBI:Oracle:TNSNAME", "user", "pass", {AutoCommit=>1, RaiseError=>1});

disconnect

Wrapper around dbh->disconnect

$dbx->disconnect;

commit

Wrapper around dbh->commit

$dbx->commit;

rollback

Wrapper around dbh->rollback

$dbx->rollback;

prepare

Wrapper around dbh->prepare with a Tie::Cache cache.

my $sth = $dbx->prepare($sql);

prepare_max_count

Maximum number of prepared statements to keep in the cache.

$dbx->prepare_max_count(128); #default
$dbx->prepare_max_count(0);   #disabled

AutoCommit

Wrapper around dbh->{'AutoCommit'}

$dbx->AutoCommit(1);
&doSomething if $dbx->AutoCommit;

For transactions that must complete together, I recommend

{ #block to keep local... well... local.
  local $dbx->dbh->{'AutoCommit'} = 0;
  $dbx->sqlinsert($sql1, @bind1);
  $dbx->sqlupdate($sql2, @bind2);
  $dbx->sqlinsert($sql3, @bind3);
} #What is AutoCommit now?  Do you care?

If AutoCommit reverts to true at the end of the block then DBI commits. Else AutoCommit is still false and still not committed. This allows higher layers to determine commit functionality.

RaiseError

Wrapper around dbh->{'RaiseError'}

$dbx->RaiseError(1);
&doSomething if $dbx->RaiseError;

{ #local block
  local $dbx->dbh->{'RaiseError'} = 0;
  $dbx->sqlinsert($sql, @bind); #do not die
}

errstr

Wrapper around $DBI::errstr

my $err = $dbx->errstr;

METHODS (Read) - SQL

sqlcursor

Returns the prepared and executed SQL cursor so that you can use the cursor elsewhere. Every method in this package uses this single method to generate a sqlcursor.

my $sth = $dbx->sqlcursor($sql,  @param); #binds are ? values are positional
my $sth = $dbx->sqlcursor($sql, \@param); #binds are ? values are positional
my $sth = $dbx->sqlcursor($sql, \%param); #binds are :key

Note: In true Perl fashion extra hash binds are ignored.

my @foo = $dbx->sqlarray("select :foo, :bar from dual",
                         {foo=>"a", bar=>1, baz=>"buz"}); #returns ("a", 1)

my $one = $dbx->sqlscalar("select ? from dual", ["one"]); #returns "one"

my $two = $dbx->sqlscalar("select ? from dual", "two");   #returns "two"

Scalar references are passed in and out with a hash bind.

my $inout = 3;
$dbx->sqlexecute("BEGIN :inout := :inout * 2; END;", {inout=>\$inout});
print "$inout\n";  #$inout is 6

Direct Plug-in for SQL::Abstract but no column alias support.

my $sabs = SQL::Abstract->new;
my $sth  = $dbx->sqlcursor($sabs->select($table, \@columns, \%where, \@sort));

sqlscalar

Returns the first row first column value as a scalar.

This works great for selecting one value.

my $scalar = $dbx->sqlscalar($sql,  @parameters); #returns $
my $scalar = $dbx->sqlscalar($sql, \@parameters); #returns $
my $scalar = $dbx->sqlscalar($sql, \%parameters); #returns $

sqlarray

Returns the SQL result as an array or array reference.

This works great for selecting one column from a table or selecting one row from a table.

my $array = $dbx->sqlarray($sql,  @parameters); #returns [$,$,$,...]
my @array = $dbx->sqlarray($sql,  @parameters); #returns ($,$,$,...)
my $array = $dbx->sqlarray($sql, \@parameters); #returns [$,$,$,...]
my @array = $dbx->sqlarray($sql, \@parameters); #returns ($,$,$,...)
my $array = $dbx->sqlarray($sql, \%parameters); #returns [$,$,$,...]
my @array = $dbx->sqlarray($sql, \%parameters); #returns ($,$,$,...)

sqlhash

Returns the first two columns of the SQL result as a hash or hash reference {Key=>Value, Key=>Value, ...}

my $hash = $dbx->sqlhash($sql,  @parameters); #returns {$=>$, $=>$, ...}
my %hash = $dbx->sqlhash($sql,  @parameters); #returns ($=>$, $=>$, ...)
my @hash = $dbx->sqlhash($sql,  @parameters); #this is ordered
my @keys = grep {!($n++ % 2)} @hash;          #ordered keys

my $hash = $dbx->sqlhash($sql, \@parameters); #returns {$=>$, $=>$, ...}
my %hash = $dbx->sqlhash($sql, \@parameters); #returns ($=>$, $=>$, ...)
my $hash = $dbx->sqlhash($sql, \%parameters); #returns {$=>$, $=>$, ...}
my %hash = $dbx->sqlhash($sql, \%parameters); #returns ($=>$, $=>$, ...)

sqlhashhash

Returns a hash where the keys are the values of the first column and the values are a hash reference of all (including the key) column values.

my $hash = $dbx->sqlhashhash($sql, @parameters); #returns {$=>{}, $=>{}, ...}
my %hash = $dbx->sqlhashhash($sql, @parameters); #returns ($=>{}, $=>{}, ...)
my @hash = $dbx->sqlhashhash($sql, @parameters); #returns ($=>{}, $=>{}, ...) #ordered

sqlarrayarray

Returns the SQL result as an array or array ref of array references ([],[],...) or [[],[],...]

my $array = $dbx->sqlarrayarray($sql,  @parameters); #returns [[$,$,...],[],[],...]
my @array = $dbx->sqlarrayarray($sql,  @parameters); #returns ([$,$,...],[],[],...)
my $array = $dbx->sqlarrayarray($sql, \@parameters); #returns [[$,$,...],[],[],...]
my @array = $dbx->sqlarrayarray($sql, \@parameters); #returns ([$,$,...],[],[],...)
my $array = $dbx->sqlarrayarray($sql, \%parameters); #returns [[$,$,...],[],[],...]
my @array = $dbx->sqlarrayarray($sql, \%parameters); #returns ([$,$,...],[],[],...)

sqlarrayarrayname

Returns the SQL result as an array or array ref of array references ([],[],...) or [[],[],...] where the first row contains an array reference to the column names

my $array = $dbx->sqlarrayarrayname($sql,  @parameters); #returns [[$,$,...],[]...]
my @array = $dbx->sqlarrayarrayname($sql,  @parameters); #returns ([$,$,...],[]...)
my $array = $dbx->sqlarrayarrayname($sql, \@parameters); #returns [[$,$,...],[]...]
my @array = $dbx->sqlarrayarrayname($sql, \@parameters); #returns ([$,$,...],[]...)
my $array = $dbx->sqlarrayarrayname($sql, \%parameters); #returns [[$,$,...],[]...]
my @array = $dbx->sqlarrayarrayname($sql, \%parameters); #returns ([$,$,...],[]...)

Create an HTML table with CGI

my $cgi  = CGI->new;
my $html = $cgi->table($cgi->Tr([map {$cgi->td($_)} $dbx->sqlarrayarrayname($sql, @param)]));

sqlarrayhash

Returns the SQL result as an array or array ref of hash references ({},{},...) or [{},{},...]

my $array = $dbx->sqlarrayhash($sql,  @parameters); #returns [{},{},{},...]
my @array = $dbx->sqlarrayhash($sql,  @parameters); #returns ({},{},{},...)
my $array = $dbx->sqlarrayhash($sql, \@parameters); #returns [{},{},{},...]
my @array = $dbx->sqlarrayhash($sql, \@parameters); #returns ({},{},{},...)
my $array = $dbx->sqlarrayhash($sql, \%parameters); #returns [{},{},{},...]
my @array = $dbx->sqlarrayhash($sql, \%parameters); #returns ({},{},{},...)

This method is best used to select a list of hashes out of the database to bless directly into a package.

my $sql     = q{SELECT COL1 AS "id", COL2 AS "name" FROM TABLE1};
my @objects = map {bless $_, MyPackage} $dbx->sqlarrayhash($sql,  @parameters);
my @objects = map {MyPackage->new(%$_)} $dbx->sqlarrayhash($sql,  @parameters);

The @objects array is now a list of blessed MyPackage objects.

sqlarrayhashname

Returns the SQL result as an array or array ref of hash references ([],{},{},...) or [[],{},{},...] where the first row contains an array reference to the column names

my $array = $dbx->sqlarrayhashname($sql,  @parameters); #returns [[],{},{},...]
my @array = $dbx->sqlarrayhashname($sql,  @parameters); #returns ([],{},{},...)
my $array = $dbx->sqlarrayhashname($sql, \@parameters); #returns [[],{},{},...]
my @array = $dbx->sqlarrayhashname($sql, \@parameters); #returns ([],{},{},...)
my $array = $dbx->sqlarrayhashname($sql, \%parameters); #returns [[],{},{},...]
my @array = $dbx->sqlarrayhashname($sql, \%parameters); #returns ([],{},{},...)

sqlarrayobject

Returns the SQL result as an array of blessed hash objects in to the $class namespace.

my $array    = $dbx->sqlarrayobject($class, $sql,  @parameters); #returns [bless({}, $class), ...]
my @array    = $dbx->sqlarrayobject($class, $sql,  @parameters); #returns (bless({}, $class), ...)
my ($object) = $dbx->sqlarrayobject($class, $sql,  {id=>$id});   #$object is bless({}, $class)

sqlsort (Oracle Specific?)

Returns the SQL statement with the correct ORDER BY clause given a SQL statement (without an ORDER BY clause) and a signed integer on which column to sort.

my $sql = $dbx->sqlsort(qq{SELECT 1,'Z' FROM DUAL UNION SELECT 2,'A' FROM DUAL}, -2);

Returns

SELECT 1,'Z' FROM DUAL UNION SELECT 2,'A' FROM DUAL ORDER BY 2 DESC

Note: The sqlsort method is no longer preferred. It is recommended to use the newer sqlwhere capability.

sqlarrayarraynamesort

Returns a sqlarrayarrayname for $sql sorted on column $n where n is an integer ascending for positive, descending for negative, and 0 for no sort.

my $data = $dbx->sqlarrayarraynamesort($sql, $n,  @parameters);
my $data = $dbx->sqlarrayarraynamesort($sql, $n, \@parameters);
my $data = $dbx->sqlarrayarraynamesort($sql, $n, \%parameters);

Note: $sql must not have an "ORDER BY" clause in order for this function to work correctly.

Note: The sqlarrayarraynamesort method is no longer preferred. It is recommended to use the newer sqlwherearrayarrayname capability.

METHODS (Read) - SQL::Abstract

Please note the "abs" API is a 100% pass through to SQL::Abstract. Please reference the SQL::Abstract documentation for syntax assistance with that API.

abscursor

my $return = $dbx->sqlexecute($sql, {in=>$in, out=>\$out});

Note: Currently sqlupdate, sqlinsert, sqldelete, and sqlexecute all point to the same method. This may change in the future if we need to change the behavior of one method. So, please use the correct method name for your function.

METHODS (Write) - Bulk - SQL

bulksqlinsertarrayarray

Insert records in bulk.

my @arrayarray = (
                  [$data1, $data2, $data3, $data4, ...],
                  [@row_data_2],
                  [@row_data_3], ...
                 );
my $count      = $dbx->bulksqlinsertarrayarray($sql, \@arrayarray);

bulksqlinsertarrayhash

Insert records in bulk.

my @columns   = ("Col1", "Col2", "Col3", "Col4", ...);                         #case sensitive with respect to @arrayhash
my @arrayhash = (
                 {C0l1=>data1, Col2=>$data2, Col3=>$data3, Col4=>$data4, ...}, #extra hash items ignored when sliced using @columns
                 \%row_hash_data_2,
                 \%row_hash_data_3, ...
                );
my $count     = $dbx->bulksqlinsertarrayhash($sql, \@columns, \@arrayhash);

bulksqlinsertcursor

Insert records in bulk.

Step 1 select data from table 1 in database 1

my $sth1  = $dbx1->sqlcursor('Select Col1 AS "ColA", Col2 AS "ColB", Col3 AS "ColC" from table1');

Step 2 insert in to table 2 in database 2

my $count = $dbx2->bulksqlinsertcursor($sql, $sth1);

Note: If you are inside a single database, it is much more efficient to use insert from select syntax as no data needs to be transferred to and from the client.

bulksqlupdatearrayarray

Update records in bulk.

my @arrayarray   = (
                    [$data1, $data2, $data3, $data4, $id],

                   );
my $count        = $dbx->bulksqlupdatearrayarray($sql, \@arrayarray);

METHODS (Write) - Bulk - SQL::Abstract-like

These bulk methods do not use SQL::Abstract but our own similar SQL insert and update methods.

bulkabsinsertarrayarray

Insert records in bulk.

my @columns    = ("Col1", "Col2", "Col3", "Col4", ...);
my @arrayarray = (

                 \%row_hash_data_3, ...
                );
my $count     = $dbx->bulkabsinsertarrayhash($table, \@columns, \@arrayhash);

bulkabsinsertcursor

Insert records in bulk.

Step 1 select data from table 1 in database 1

my $sth1  = $dbx1->sqlcursor('Select Col1 AS "ColA", Col2 AS "ColB", Col3 AS "ColC" from table1');

Step 2 insert in to table 2 in database 2

my $count = $dbx2->bulkabsinsertcursor($table2, $sth1);

my $count = $dbx2->bulkabsinsertcursor($table2, \@columns, $sth1); #if your DBD/API does not support column alias support

Note: If you are inside a single database, it is much more efficient to use insert from select syntax as no data needs to be transferred to and from the client.

bulkabsupdatearrayarray

Update records in bulk.

my @setcolumns   = ("Col1", "Col2", "Col3", "Col4");
my @wherecolumns = ("ID");
my @arrayarray   = (
                    [$data1, $data2, $data3, $data4, $id],

                    [@row_data_3], ...
                   );
my $count        = $dbx->bulkabsupdatearrayarray($table, \@setcolumns, \@wherecolumns, \@arrayarray);

Constructors

abs

Returns a SQL::Abstract object

Methods (Informational)

dbms_name

Return the DBMS Name (e.g. Oracle, MySQL, PostgreSQL)

Methods (Session Management)

These methods allow the setting of Oracle session features that are available in the v$session table. If other databases support these features, please let me know. But, as it stands, these methods are non operational unless SQL_DBMS_NAME is Oracle.

module

Sets and returns the v$session.module (Oracle) value.

Note: Module is set for you by DBD::Oracle. However you may set it however you'd like. It should be set once after connection and left alone.

$dbx->module("perl@host");      #normally set by DBD::Oracle
$dbx->module($module, $action); #can set initial action too.
my $module = $dbx->module();

client_info

Sets and returns the v$session.client_info (Oracle) value.

$dbx->client_info("Running From crontab");
my $client_info = $dbx->client_info();

You may use this field for anything up to 64 characters!

$dbx->client_info(join "~", (ver => 4, realm => "ldap", grp =>25)); #tilde is a fairly good separator
my %client_info = split(/~/, $dbx->client_info());

action

Sets and returns the v$session.action (Oracle) value.

$dbx->action("We are Here");
my $action = $dbx->action();

Note: This should be updated fairly often. Every loop if it runs for more than 5 seconds and may end up in V$SQL_MONITOR.

while ($this) {
  local $dbx->{'action'} = "This Loop"; #tied to the database with a little Perl sugar
}

client_identifier

Sets and returns the v$session.client_identifier (Oracle) value.

$dbx->client_identifier($login);
my $client_identifier = $dbx->client_identifier();

Note: This should be updated based on the login of the authenticated end user. I use the client_info->{'realm'} if you have more than one authentication realm.

For auditing add this to an update trigger

new.UPDATED_USER = sys_context('USERENV', 'CLIENT_IDENTIFIER');

TODO

Sort functions sqlsort and sqlarrayarraynamesort may not be portable. It is now recommend to use sqlwhere methods instead.

Add some kind of capability to allow hash binds to bind as some native type rather than all strings.

Hash binds scan comments for bind variables e.g. /* :variable */

Improve error messages
