NAME

	 DBIx::SearchBuilder::Handle::Pg - A Postgres specific Handle object

SYNOPSIS

DESCRIPTION

       This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of Postgres.

METHODS

   Connect
       Connect takes a hashref and passes it off to SUPER::Connect; Forces the timezone to GMT it returns a database handle.

   Insert
       Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.

       In case of insert failure, returns a Class::ReturnValue object preloaded with error info.

   InsertQueryString
       Postgres sepcific overriding method for "InsertQueryString" in DBIx::SearchBuilder::Handle.

   IdSequenceName TABLE
       Takes a TABLE name and returns the name of the  sequence of the primary key for that table.

   BinarySafeBLOBs
       Return undef, as no current version of postgres supports binary-safe blobs

   ApplyLimits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
       takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;

   _MakeClauseCaseInsensitive FIELD OPERATOR VALUE
       Takes a field, operator and value. performs the magic necessary to make your database treat this clause as case insensitive.

       Returns a FIELD OPERATOR VALUE triple.

   DistinctQuery STATEMENTREF
       takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.

   SimpleDateTimeFunctions
       Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.

   ConvertTimezoneFunction
       Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.

       In Pg time and timestamp data types may be "with time zone" or "without time zone".  So if Field argument is timestamp "with time zone"
       then From argument is not required and is useless. Otherwise From argument identifies time zone of the Field argument that is "without time
       zone".

       For consistency with other DBs use timestamp columns without time zones and provide From argument.

NAME

       DBIx::SearchBuilder::Union - Deal with multiple SearchBuilder result sets as one

SYNOPSIS

	 use DBIx::SearchBuilder::Union;
	 my $U = new DBIx::SearchBuilder::Union;
	 $U->add( $tickets1 );
	 $U->add( $tickets2 );

	 $U->GotoFirstItem;
	 while (my $z = $U->Next) {
	   printf "%5d %30.30s
", $z->Id, $z->Subject;
	 }

WARNING

       This module is still experimental.

DESCRIPTION

       Implements a subset of the DBIx::SearchBuilder collection methods, but enough to do iteration over a bunch of results.  Useful for
       displaying the results of two unrelated searches (for the same kind of objects) in a single list.

METHODS

   new
       Create a new DBIx::SearchBuilder::Union object.	No arguments.

   add $sb
       Add a searchbuilder result (collection) to the Union object.

       It must be the same type as the first object added.

   First
       Return the very first element of the Union (which is the first element of the first Collection).  Also reset the current pointer to that
       element.

   Next
       Return the next element in the Union.

   Last
       Returns the last item

   Count
       Returns the total number of elements in the Union'ed Collection

   GotoFirstItem
       Starts the recordset counter over from the first item. the next time you call Next, you'll get the first item returned by the database, as
       if you'd just started iterating through the result set.

   IsLast
       Returns true if the current row is the last record in the set.

   ItemsArrayRef
       Return a refernece to an array containing all objects found by this search.

       Will destroy any positional state.
