MS SQL Development Training Fees

Just read the book, type and run the code, and work the chapter examples. If you work the book, you will be ahead of many SQL Server programmers.

You’ll understand declarative set-based interaction with SQL Server and know many critical language elements and built-in functions.

The first couple chapters address SQL Server internals, DDL, and basic normalisation of relational data for applications. It doesn’t cover other relational data structures such as star schema.

After that, it dives into solid querying patterns and eventually gets into DML.

Some object-oriented programmers have difficulty writing good declarative set-based T-SQL code. But programmers that are fluent in object-oriented programming and scripting, and also fluent in T-SQL declarative set-based programming fundamentals, often build apps with fewer performance bottlenecks and require less rework. In my experience.

What is WorkTable in SQL Server?

If you run above query, there is good chance that it will give you following details in the message windows.

Table ‘Product’. Scan count 2, logical reads 30, physical reads 1, read-ahead reads 17, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.
Table ‘Worktable‘. Scan count 1, logical reads 8110, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0.

You will notice in the message there is a table called worktable. However, if you see the original table there is no worktable. This is where the question has originated.

The question in another word is, "Why does statistics show the worktable where it is not there in the original query?"

Well, the answer is very simple, quite often SQL Server has to perform any logical operations for any specific queries and to perform these logical operations SQL Server has to build a worktable. Worktables are built in tempdb and are dropped automatically when they are no longer needed.

Worktables:

The relational engine may need to build a worktable to perform a logical operation specified in an SQL statement. Worktables are internal tables that are used to hold intermediate results. Worktables are generated for certain GROUP BY, ORDER BY, or UNION queries. For example, if an ORDER BY clause references columns that are not covered by any indexes, the relational engine may need to generate a worktable to sort the result set into the order requested. Worktables are also sometimes used as spools that temporarily hold the result of executing a part of a query plan. Worktables are built in tempdb and are dropped automatically when they are no longer needed.
