Ssis Documentation How To Automate The

This video shows how to automate the documentation of SSIS packages from three different data sources with ApexSQL Doc.Microsoft SQL Server provides integration services for building SSIS packages to design complex solutions, workflows, data migration, and transformations. Automating SSIS package documentation. In this article, you can learn how to automate the process of SQL database documentation, using ApexSQL Doc. Use the A-Z search feature to locate a Worker topic.Each topic heading is followed by related modules, job aids, handouts, presentations, scripts and tip sheets associated with the task, e.g., C for Court Action.This article explores the SSIS Precedence Constraints, along with examples and scenarios.Document SQL databases automatically. Time and time again, you will always hear SQL Server DBA's express the need to document your SQL queries, views, stored procedures, and functions within the text of the statements.SSIS Worker Documentation. What methods can be used to document and sequence SSIS packages, connections, and tasks 'inline' just as we do our SQL Code Solution.

The standard and default constraints is a success constraint. We can see a green color arrow in the following image that defines precedence constraints:We can see green, red, and grey connectors in the Control Flow to link tasks together. Control flow also allows defining the order in which the task will run.LetвЂ™s add two execute SQL tasks in the control flow area and configure them to execute the T-SQL statements.Note: You can refer to SSIS articles for understanding SSIS configurations.I require executing the tasks with the following conditions:If the SQL task 1 fails, then execute task 2If we execute the package without any additional configuration, it executes both the tasks in parallel:We use SSIS precedence constraints to define the program flow from one task to another. We do not want all the tasks to execute at the same time. Package explorers: Here, we can explore the SSIS package connections, log providers, variables and parametersIn the control flow, we can define multiple workflows, tasks in a single SSIS package.

Now, it executes the task 2 as defined in the failure condition of SQL task 1:Another SSIS precedence constraint is completion. It also shows an annotation for failures.In this scenario, the package executes in the following manner:If the SQL task 1 fails, then only execute task 2In the following screenshot, we can see that SSIS does not execute the task 2 because task 1 status is successful:Modify the package so that SQL task 1 fails and execute it again. Right-click on the arrow and choose different precedence, as shown in the following screenshot:LetвЂ™s change it to failure and arrow colour changes to Red.

Constrained Executable: It is the destination task, and its execution depends on the defined precedence constraints and outcome of precedence executableDouble-click on precedence, and it opens the precedence constraints editor:In this editor, we have the following SSIS Precedence Constraints options:Here, we define the precedence constraints as defined above. Precedence Executable: It is the source from where we define the precedence constraints LetвЂ™s have a summary theoretically and explore it further.As highlighted above, we have the following precedence constraints in SSIS.First, let me give brief information about the components involved in SSIS precedence constraints:

Evaluation operation: Expression and Constraint The output of both must be true so that constrained executable can run.For example, open the SSIS precedence constraint editor and change the options as follows: In the following screenshot, all three precedence constraints with executing SQL task 1:If we choose expressions in SSIS precedence constraints, it evaluates the expression and if the expression is true, then the constrained executable runs.For example, in the following screenshot, we defined an expression for checking the weekday as per the following example:Click on Test, and it evaluates the expression:Click OK, and it changes the expression symbol fx as shown below:It runs the constrained executable if the evaluated expression is true:If the expression returns false condition, it doesnвЂ™t execute the constrained executable:In this mode, the SSIS package evaluates both precedence constraint and expression. The color for completion precedence constraint is blue.We can define multiple SSIS precedence constraints for a single task in the SSIS package. Its color is red.It runs the constrained executable regardless of the state of precedence executable task. The color of success precedence is green.In this constraint, precedence executable must fail so that the constrained executable can execute.

Add one more execute SQL task and connect it to SQL task 2:Now execute SQL task contains two precedences defined on it:Intentionally, I have made a syntax error in SQL task 3 so that it should fail. It executes the constrained executable as wellLetвЂ™s make things more complicated. Looking at the above example, change the SSIS precedence constraints editor to reflect this change:Execute the SSIS package and note the difference:SSIS Precedence constraint returns true because execute SQL task 1 is successWe have one true value in the above conditions, and it returns true value. Upon investigation, we find the following facts:Precedence constraint returns true because execute SQL task 1 is a successThe expression does not meet the criteria and returns a false valueThe combination of precedence constraints and expressions return false, and it does not execute the constrained executableLetвЂ™s change the expression so that it returns true, and it executes the constrained executable.Expression meets the criteria and returns a true valueThe combination of precedence constraints and expressions return true, and it executes the constrained executable as wellSimilarly, we can change it to failure precedence constraint and expression:In this option, at least one of the SSIS precedence constraint or expression should be true.

Due to this, we did not see the execution of SQL task 2 because one of the precedence constraints is false (failure of SQL task 3).LetвЂ™s change the value of multiple constraint property- Logical ORвЂ“ One constraint must evaluate to True:Click OK, and you can note the changes in SSIS precedence constraints lines. Open the precedence constraint editor, and you can see the following property for multiple constraints:If we have multiple constraints for a task, this property controls the behavior for the constrained executable execution.By default, all the constraints must evaluate to True. LetвЂ™s investigate the reason for it.
