What are different types of transformations in SSIS?

What are different types of transformations in SSIS?

Here is a list of the different types of transformations – enjoy!

• Non-Blocking Synchronous Streaming Transformations (Fastest)
• Non-Blocking Synchronous Row-Based Transformations (Fast)
• Semi-Blocking Asynchronous Transformations (Medium)
• Fully Blocking Asynchronous Transformations (Slowest)

What are SSIS transformations?

SQL Server Integration Services transformations are the components in the data flow of a package that aggregate, merge, distribute, and modify data. Transformations can also perform lookup operations and generate sample datasets.

What is lookup transformation in SSIS with example?

The Lookup transformation performs lookups by joining data in input columns with columns in a reference dataset. You use the lookup to access additional information in a related table that is based on values in common columns.

What is the difference between union all and Merge transformations in SSIS?

The main difference is that Union All doesn’t require that the data sources are sorted, nor does its output. Besides, Union All accepts more than two inputs while Merge transformation doesn’t. Before illustrating how to use the Merge transformation, we will explain several approaches to sort data sources in SSIS.

What are the different types of transformations available in data flow task?

SSIS Data Flow Transformations Aggregate: Like a GROUP BY in T-SQL. Conditional Split: Splits out streams based on one or more conditions. Data Conversion: Allows you to convert columns from one data type to another. Derived Column: Allows you to manipulate existing columns or create new columns using expressions.

What is conditional split transformation in SSIS?

The Conditional Split transformation can route data rows to different outputs depending on the content of the data. The implementation of the Conditional Split transformation is similar to a CASE decision structure in a programming language.

What is Fuzzy Lookup transformation in SSIS?

The Fuzzy lookup is another lookup transformation available in SSIS. Rather than using equality join to link the main data pipeline to the reference data set, it uses fuzzy matching to return one or more close matches from the lookup table.

What is synchronous and asynchronous transformation in SSIS?

All source adapters are asynchronous, they create two buffers; one for the success output and one for the error output. All destination adapters, on the other hand, are synchronous. Semi-Blocking Asynchronous Transformations require a subset of the data to be collected before they can be sent to the destination(s).

What are the different types of containers in SSIS?

Integration Services provides four types of containers for building packages….

• SqlServer. Dts. Runtime. ForEachLoop.
• SqlServer. Dts. Runtime. ForLoop.
• SqlServer. Dts. Runtime. Sequence.
• SqlServer. Dts. Runtime. TaskHost.

What is difference between Lookup and Fuzzy Lookup in SSIS?

The Lookup transformation uses an equi-join to locate matching records in the reference table. It returns records with at least one matching record, and returns records with no matching records. In contrast, the Fuzzy Lookup transformation uses fuzzy matching to return one or more close matches in the reference table.
