NAME

Win32::OLE::CrystalRuntime::Application::Report - Perl Interface to the Crystal Report OLE Object

SYNOPSIS

  use Win32::OLE::CrystalRuntime::Application;
  my $application=Win32::OLE::CrystalRuntime::Application->new;
  my $report=$application->report(filename=>$filename);
  $report->export(format=>"pdf", filename=>"export.pdf");

DESCRIPTION

This package is a wrapper around the OLE object for a Crystal Report.

USAGE

CONSTRUCTOR

You must construct this object from a Win32::OLE::CrystalRuntime::Application object as the ole object is constructed at the same time and is generated from the application->ole object.

  use Win32::OLE::CrystalRuntime::Application;
  my $application=Win32::OLE::CrystalRuntime::Application->new;
  my $report=$application->report(filename=>$filename);

METHODS

filename

Returns the name of the report filename. This value is read only after object construction.

  my $filename=$report->filename;

Set on construction

  my $report=Win32::OLE::CrystalRuntime::Application::Report->new(
               filename=>$filename,
             );

ole

Returns the OLE report object. This object is the Win32::OLE object that was constructed during initialization from the $application->report() method.

application

Returns the application object.

  my $application=$report->application;

Set on construction in the $application->report method.

  my $report=Win32::OLE::CrystalRuntime::Application::Report->new(
               application=>$application
             );

setConnectionProperties

Sets report ConnectionProperties correctly in the correct order.

  $report->setConnectionProperties("Server"   => "TNSNAME",
                                   "User ID"  => "login",
                                   "Password" => "password");

Sets report ConnectionProperties correctly in the correct order and set Schema for tables.

  $report->setConnectionProperties("Server"   => "TNSNAME",
                                   "User ID"  => "login",
                                   "Password" => "password",
                                   "Schema"   => "schematxt");

Tables where you do not want to reset the schema alias them with a "_" (e.g. 'SELECT 1 FROM SYS.DUAL "_DUAL"').

Current Limitations: Oracle support for crdb_oracle.dll only Current Limitations: SubReports are only searched one level deep; not recursive.

setParameters

Sets the report parameters.

  $report->setParameters($key1=>$value1, $key2=>$value2, ...);  #Always pass values as strings and convert in report
  $report->setParameters(%hash);

export

Saves the report in the specified format to the specified filename.

  $report->export(filename=>"report.pdf");  #default format is pdf
  $report->export(format=>"pdf", filename=>"report.pdf");
  $report->export(formatid=>31, filename=>"report.pdf"); #pass format id directly

FormatID

Returns a hash of common format extensions and CRExportFormatType IDs. Other formats are supported with export(formatid=>$id)

  my $hash=$report->FormatID;           #{pdf=>31, xls=>36};
  my @orderedlist=$report->FormatID;    #(pdf=>31, xls=>36, ...)
  my $id=$report->FormatID->{"pdf"};    #$ i.e. 31

  my $list=$report->objects(type=>5); #[] #crSubreportObject
  my @list=$report->objects(type=>1); #() #crFieldObject

subreports

Returns all OLE subreports in the report

Note: This is currently only one level deep and not recursive!!!

Schema Helpers

Schema Helpers are only used if you set the "Schema" property in the setConnectionProperties method.

When moving a Crystal Report rpt file among development, alpha and production database typically the schema changes. These functions will help you redefine the schemas so that you can develop a report against a development database, test the same report against an alpha database, and deploy the same exact report to production.

These helpers trigger from the prefix of the table alias since the schema is not available from the runtime OLE object.

shadow_schema_prefixed

Set the trailing part of the schema on these schemas. This is popular for alias or "shadow" type schema configurations.

Default: "SHADOW_"

Example: "SELECT * FROM SHADOW_DEV1.TABLE1 _pre_table1" becomes "SELECT * FROM SHADOW_PROD1.TABLE1 _pre_table1"

shadow_schema_postfixed

Set the leading part of the schema on these schemas. This is popular for alias or "shadow" type schema configurations.

Default: "_SHADOW"

Example: "SELECT * FROM DEV1_SHADOW.TABLE1 _post_table1" becomes "SELECT * FROM PROD1_SHADOW.TABLE1 _post_table1"

shadow_schema_prefixed_token

Token used in the table alias

Default: "_pre_"

  $report->shadow_schema_prefixed_token("_token_");

Example: "SELECT * FROM SHADOW_DEV1.TABLE _token_table1" becomes "SELECT * FROM SHADOW_PROD1.TABLE _token_table1"

shadow_schema_postfixed_token

Token used in the table alias

Default: "_post_"

  $report->shadow_schema_postfixed("_DAPI");
  $report->shadow_schema_postfixed_token("_dapi_");

Example: "SELECT * FROM DEV1_DAPI.TABLE1 _dapi_table1" becomes "SELECT * FROM PROD1_DAPI.TABLE1 _dapi_table1"
