SQL Scripting for ETL

It is possible to load raw data into QPR ProcessAnalyzer and do the data transformation and loading into QPR ProcessAnalyzer Service via Load Scripts using temporary database tables, so that the resulting transformed data can be used for analyses in QPR ProcessAnalyzer.

A user with the ManageIntegrations and RunScripts permissions can define a Load Script in the Model Properties dialog. The Load Script consists of SQL statements and QPR ProcessAnalyzer commands that take the preceding SQL statements as parameters.

Supported QPR ProcessAnalyzer Commands in Load Scripts

--#GetAnalysis

Creates an analysis from the data which the preceding SQL statements given as parameters provide. The analysis parameters have to be defined in the SQL SELECT statements as follows:

'<Analysis Parameter>', '<Value>'

See Analysis Parameters for a list of supported analysis parameters in QPR ProcessAnalyzer.

The --#GetAnalysis command supports the following analysis types:

Case Analysis (5)

Event Analysis (6)

Event Type Analysis (7) Note: analysis is in table format only.

Variation Analysis (8) Note: analysis is in table format only.

User Report (11)

OperationLog Analysis (12)

Flow Analysis (13)

Influence Analysis (14)

Integration Table Analysis (18)

--#ImportEvents

Loads Events from the data which the preceding SQL statements given as parameters provide.

--#ImportCaseData

Loads Case Attributes from the data which the preceding SQL statements given as parameters provide.

--#RemoveEvents

Removes all events in the model, but retains Cases, Event Types, and Variations.

--#ShowReport

Creates a new excel sheet containing a two dimensional matrix that contains the results of the user specified SQL query. The result column names are the field names of the SQL query and the rows are the actual data rows of the SQL query. The report can be used to see, for example, the events that would be loaded into QPR ProcessAnalyzer before actually loading them. If the events have problems that cause errors when loaded it is useful to be able to see the row data in a report.

Parameters

The parameters defined in the SQL SELECT statements:

''

Mandatory. The database query whose results are to be returned.

'<Analysis Parameter>', '<Value>'

Optional. The Analysis Parameters given for the operation. Some suggested parameters to be used:

'Title', '<Title of the report>'

Name of the created report (used as sheet name in QPR ProcessAnalyzer Excel Client). Any existing sheet with the same title will be overwritten, so a script containing multiple ShowReport commands should use a unique title for each of the ShowReport commands. If not given, "Report" will be used as a default.

'MaximumCount', '<Value>'

The maximum number of rows to show (0 = all, default = 1000).

Example

The following example opens the data table identified by data table name "SqlTable" and project name "Test" as a report.

(SELECT 'AnalysisType', '18') UNION ALL

(SELECT 'ProjectName', 'Test') UNION ALL

(SELECT 'DataTableName', 'SqlTable') UNION ALL

(SELECT 'TargetTable', '#AnalysisResult')

--#GetAnalysis

SELECT * FROM #AnalysisResult;

(SELECT 'Title', 'Report1') UNION ALL

(SELECT 'MaximumCount', '0')

--#ShowReport

--#WriteLog

Adds the first column values from the preceding SQL statements to the log that is shown after the whole script execution is completed.

Example

The following example will write "Script started" and "Example" into the log.

SELECT 'Script started'

SELECT 'Example'

--#WriteLog

--#Exit

Stops the execution of the script and gives a message to the user.

Parameters

The parameters defined in the SQL SELECT statements:

'Exit', '<Value>'

Defines whether to stop the script execution. 1 = stop execution, 0 = do not stop execution.

'MessageText', '<Text>'

Text to be shown to the user after the script execution is finished if the script finished because of the Exit command, i.e. when Exit=1. The default value is "Script execution finished.", which is shown also when the script finished normally, i.e. when Exit=0.

Example

The following example stops the script execution and gives a message.

SELECT ('Exit', '1') UNION ALL

SELECT ('MessageText', 'Data from SAP not valid. Script execution will be terminated. Check source data')

--#Exit

--#ImportDataTable

Imports data to a Data Table.

Parameters

The parameters defined in the SQL SELECT statements in the order they are listed below:

'ProjectId' or 'ProjectName', '<Value>'

The id or the name of the project in which the target data table exists.

'DataTableId' or 'DataTableName', '<Value>'

The id or the name of the existing/new target data table.

'Append', '<Value>'

Defines what to do with an existing target data table contents. 1 = the existing contents in the target data table are not deleted before import, 0 = the existing contents of the target data table are deleted before the import.

''

The database query whose results are to be imported.

Example

The following example will load data from a model and put it into the "AnalysisResult" table and then add that data to the "ExampleTable" data table.

SELECT 'START

--#WriteLog

(SELECT 'AnalysisType', '6') UNION ALL

(SELECT 'MaximumCount', '0') UNION ALL

(SELECT 'ViewId', '3') UNION ALL

(SELECT 'SelectedEventAttributes', '*') UNION ALL

(SELECT 'TargetTable', '#AnalysisResult')

--#GetAnalysis

SELECT 'DataLoaded'

--#WriteLog

SELECT count(*) from [#AnalysisResult]

--#WriteLog

(SELECT 'ProjectId', '1') UNION ALL

(SELECT 'DataTableName', 'ExampleTable') UNION ALL

(SELECT 'Append', '1')

(SELECT * FROM [#AnalysisResult])

--#ImportDataTable

Example

The following example will load data from the "ExampleTable" data table in the "ExampleProject" project, put that data into the "CSV1" table and then show the contents of the "CSV" table. In effect, it shows the contents of the "ExampleTable" data table.

(SELECT 'AnalysisType', '18') UNION ALL

(SELECT 'ProjectName', 'ExampleProject') UNION ALL

(SELECT 'MaximumCount', '0') UNION ALL

(SELECT 'DataTableName', 'ExampleTable') UNION ALL

(SELECT 'TargetTable', '#CSV1')

--#GetAnalysis

(SELECT * FROM #CSV1)

(SELECT 'Title', 'CSV Table') UNION ALL

(SELECT 'MaximumCount', '0')

--#ShowReport

SQL Command Support

When transforming data, only temporary tables (#) should be used. Note that global temporary tables (##) should never be used in the SQL scripts, and using them is not allowed.

Running Load Scripts

A load script can be run in two ways:

Running a Load Script from the Model Properties Dialog

1. On the QPR ProcessAnalyzer tab of the ribbon, click Project Workspace.
2. From the model list, select the desired model that contains a load script.
3. Click Properties.
4. Click Run Script.

Running a Load Script by Importing a .pasql File

1. Write the load script into a file that has a .pasql file format.
2. On the QPR ProcessAnalyzer tab of the ribbon, click Project Workspace.
3. Click Import.
4. Select QPR ProcessAnalyzer File and click Next.
5. Click Select and choose QPR ProcessAnalyzer SQL Script File (*.pasql) from the file type menu.
6. Browse to the .pasql file containing the load script, select it, and click Open.
7. Click Next.
8. Select the import target:
   • Create New will create a new model and set it as the target of the load script.
   • Add to Existing will set the target of the load script to the selected model.

   Either way, the script in the .pasql file will be set as the Load Script of the target model.

9. Click Import.

Terminating Load Scripts

A Load Script can be terminated by the following ways:

• The user running the script can click the Cancel button when the script is running.
• A QPR ProcessAnalyzer Administrator user can terminate the script via the Operations Log.
• The SQL Server System Administrator can kill the session using the script by using e.g. SQL Server Management Studio.
• The Internet Information Services Administrator can recycle the application pool if the Load Script has caused it to hang. Note however, that this may also cause other requests by other users being processed at the same time to be aborted.
• The Windows Administrator can kill the w3wp.exe-process processing a problematic script. Note however, that this may also cause other requests by other users being processed at the same time to be aborted.

NOTE!
Terminating the Load Script will not revert any changes the script has already done in the database before the Cancel button is clicked.
