How to create a simple ETL/stored procedure error capturing database (schema model, SQL code and implementation) – Part 1

Introduction

Two part series (second part can be found HERE) on how to create and implement an ETL execution error capturing database (schema model, SQL code, implementation etc.) based on Microsoft SQL Server stored procedures default error handling capabilities.

TL;DR Version

My last client engagement required me to create an ETL errors tracking solution which would serve as a central repository for all data related to SSIS packages execution failures. Given the initial scope and assumptions pointed to a small project size, thus the number of ETL routines involved kept at a minimum, my first intention was to build a single table encompassing all key information related to the package metadata and execution state. However, as the project grew in size, execs started to demand richer, more detailed data and the constricting schema of a single table became too evident, I decided to expand it with a proper relational database schema with additional metadata attributes at all common data-grouping hierarchies i.e. instance, database, schema and objects. In addition, I have also extracted metadata pertaining to users, logins and packages which complemented the whole data set with a comprehensive suite of variables for error-related analysis. Please note that this model and the subsequently discussed implementation is based primarily on capturing errors resulting from stored procedures execution as per my project demands. Since version 2012, SQL Server included the SSISDB catalog as the central point for working with Integration Services (SSIS) projects deployed to the Integration Services server which contains a rich set of data for all execution eventualities and should be treated as a default logging option for comprehensive SSIS runtime events capture.

Below is a breakdown of a database schema model which accounts for most of the database-related objects as well as some handy information on individual packages, logins and users. First up, we have instance and database data specific tables – LogSSISErrors_Instance and LogSSISErrors_DB – in a one-to-many relationship i.e. one SQL Server instance to multiple databases.

As each database can have multiple schemas, LogSSISErrors_DB has a one-to-many relationship to LogSSISErrors_Schema table, which in turn can be further related to LogSSISErrors_Object and LogSSISErrors_Process tables, each storing object-level data. The only distinction between ‘Object’ and ‘Process’ specific tables is the fact that ‘Object’ table stores table and view metadata whereas ‘Process’ table is concerned with stored procedures, assemblies, functions and triggers, even though on the database level they are all technically treated as objects.

Error_Capture_DB_Schema_ERD_Partial_2

Both, LogSSISErrors_Object and LogSSISErrors_Process have a one-to-many relationship with LogSSISErrors_Error table – the centrepiece of all the logging activities. LogSSISErrors_Error table is also linked up with LogSSISErrors_User, LogSSISErrors_Package and LogSSISErrors_Login tables, storing users, local SSIS packages and logins metadata.

LogSSISErrors_user table is also connected to LogSSISErrors_DB table as one database can have multiple users created against it.

All the data represented by the above schema, with the exception of LogSSISErrors_Package table entries, should be available by querying either catalog views, information schema views or system stored procedures/functions. Most of the tables names are self-explanatory and can be easily referred back to the function they play and relevant metadata information. In case of LogSSISErrors_Process and LogSSISError_Object, these tables’ data comes from the same query with the distinction made on the object type i.e. view and tables, whereas stored procedures are bucketed as processes (even though technically they are objects too), thus placed in the LogSSISErrors_Process table. In case of LogSSISErrors_Package table, the package metadata is not stored on the server level but can be sourced from a .dtsx file using T-SQL. This part of solution was made available thanks to Jamie Thompson’s scripts which you can read about in detail in his post HERE, I simply adopted his technique for my solution.

The script used to create all database objects and populate those with SQL Server instance metadata is close to 1800 lines long so in this post I’ll only go through sections of it, skipping all the boilerplate SQL; however, a full working version is available for download from my OneDrive folder HERE. The script is divided into a few sections, main parts being AdminDBA database metadata collection for subsequent objects recreation and second part determined by a conditional logic where  a counts of foreign key constraints and a count of tables from two table variables created is compared.

First part creates two table variables storing objects AdminDBA objects metadata and foreign key constraints referencing individual tables. If those tables have already been created and relationships exist, than the rest of the script utilizes this metadata in subsequent execution. The following T-SQL generates table variables and their content.

By design, after the the database and objects have been (re)created, the number of foreign key constraints should be one fewer than the number of tables. The below piece of SQL compares the counts of foreign key constraints and the count of tables from two table variables at which point one of the two possible scenarios can be triggered – if the count is comparable than the objects are re-created using the data encapsulated in table variables which already store DDL code for individual tables as well as foreign key constraints. If, on the other hand, the count is not comparable, a different part of stored procedure gets executed, this time responsible for recreating objects based on the hard-coded DDL statements and foreign key constraints.

IF NOT EXISTS ( SELECT  COUNT(*) - 1 AS ct
                FROM    @TempFKs a
                EXCEPT
                SELECT  COUNT(*)
                FROM    @TempTbls b )
		AND EXISTS ( SELECT TOP 1 1 FROM @TempTbls )

Most of the SQL Server databases’ metadata comes from storing the results of the below query which extracts database, schema and objects information for each database and temporarily stores it in a table variable.

Instance level metadata comes mainly from appending different arguments to a SERVERPROPERTY function to return instance-specific information. Database users metadata comes from sys.database_principals, whereas login details are returned from sys.server_principals catalog views.

SSIS package metadata is a little bit more complex to interrogate. In case of LogSSISErrors_Package table, the package metadata is not stored on the server level but can be sourced from a .dtsx file using T-SQL. As mentioned before, this part of solution was made available thanks to Jamie Thompson’s scripts which you can read about in detail in his post HERE. This part of script accesses the file system and reads .dtsx XML content, storing relevant attributes in LogSSISErrors_Package table.

Upon execution completion this code should create a small set of tables starting with LogSSISErrors prefix and metadata entries in some or all tables based on your local SQL Server instance as per the image below.

Error_Capture_DB_AdminDBA_Objects_OnStart

In the NEXT POST I will go through the process of creating a sample test environment, an SSIS package running an error-generating process and another variation of the above stored procedure used to update the database as the environment changes occur. Also, all the code used in this solution can be downloaded from my OneDrive folder HERE.
