What is the difference between execute SQL and execute T-SQL tasks in SSIS?
T-SQL (Transact-SQL) is a set of SQL language programming extensions developed by Sybase and Microsoft. Execute SQL Task in SSIS: SqlStatementSource Expressions vs Variable Source Types. Execute SQL Tasks in SSIS: Output Parameters vs Result Sets.
Why would you use an execute TSQL task rather than an Execute SQL task?
The Execute T-SQL Statement task tasks less memory, parse time, and CPU time than the Execute SQL task, but is not as flexible. If you need to run parameterized queries, save the query results to variables, or use property expressions, you should use the Execute SQL task instead of the Execute T-SQL Statement task.
Is SSIS used for ETL?
MicrosoftSQL Server Integration Services (SSIS) is a platform for building high-performance data integration solutions, including extraction, transformation, and load (ETL) packages for data warehousing.
Is SSIS a good tool?
SSIS is ideal for developers and companies with large, complex data volumes. Developers working with SSIS typically use Visual Studio and write many lines of complex code with a big margin for error. While many consider it an excellent tool for ETL, there are alternatives that may be better depending on your needs.
Which task allows you to run a query to transform data?
The Execute SQL task, the OLE DB source, the OLE DB destination, and the Lookup transformation can use SQL queries. In the Execute SQL task, the SQL statements can create, update, and delete database objects and data; run stored procedures; and perform SELECT statements.
What’s the difference between T-SQL and SSIs?
T-SQL is just an extension of ANSI SQL so the jump from one to the other is not that large. SSIS is this extra thing you have to learn on top of your existing SQL skills. Additionally, SSIS can be rather complex and it takes a while to learn how to create even decently performing packages. Why?
Is it better to use T-SQL or Python for ETL?
If you are using a lot of SSIS packages for complex ETL, this conversion process can be quite lengthy. You will also have to regression test everything. In any scenario, upgrading your SSIS packages is an unnecessary cost. Neither Python nor T-SQL suffer from forward compatibility issues.
Can you use execute SQL task in SSIs?
If you are building SSIS packages to be used as SQL Agent maintenance plans, you cannot use the Execute SQL Task since it is not supported. If you need to generate result sets from your statement and to store them within SSIS variables, you should use Execute SQL Task since this feature is not supported within the other task.
Which is better execute SQL task or execute T-SQL statement task?
The Execute T-SQL Statement task uses ADO.NET connections only, which means that it requires that the .NET framework should be installed on the machine. You may note that Execute SQL Task is more popular and it is widely used by developers; you will find hundreds of related topics, tutorials online.
