There are situations in which a server database is the proper solution; there are other situations in which a simple desktop database is theproper solution. I would kindly suggest that you test your two example queries, because I would hazard a guess that you'll find that the performance is the exact opposite of what you expect
sql server - GO After every T-SQL statement - Database Administrators Stack Exchange
After I execute the PowerShell code to send those batches and statements, I see the following results: As you can see from the screenshot, it's clear how the statements are divided up into the two different batches, also evident by the means we used to call the batches. But what is a batch?? This BOL reference says it best: A batch is a group of one or more Transact-SQL statements sent at the same time from an application to SQL Server for execution
Example of where CASE expressions can be used include in the SELECT list, WHERE clauses, HAVING clauses, IN lists, DELETE and UPDATE statements, and inside of built-in functions. Another Problem is that : I fatch Max(columnName) and max value+1 my next value for insert statement , Now point is that when two user aceess same max value and insert same value into table than a confliction or violation of primary key error thrown by software
Finally, you might also have issues with NULL values and performance problems in general as you nest these IN clauses one inside another, especially if you use the even more dreaded "Nested WHERE-NOT IN" anti-pattern. Can you provide a specific example where a nested in performs better? I'm definitely curious, it would be very interesting to see something that performs better with all the INs, and I'm willing to revise my statements if we can find that scenario.In terms of extensibility, if technique A always performs equally or better than technique B, they have approximately the same complexity, and technique A also has the benefit of better extensibility, I will personally stick with technique A
Although a common table expression (CTE) can be used to recursively expand a tree relationship, internally it builds the entire tree before applying any filters to display the tree, starting at a specific level

Nested if statements in SQL Server stored procedure SELECT statement - Stack Overflow
I am trying to build a stored procedure (MS SQL Server 2005) that takes a number of passed in values and in effect dynamically builds up the SQL as you would with inline SQL. I've hugely simplified the code in the above example for clarity, since it's the general concept of a nested IF statement with SELECT and ORDER BY that I'm inquiring about

As most SSIS developers know SSIS Expressions are used to drive several key tidbits of a package components as the Conditional Split, Package Variables value assignments, Derived Column Transformation, form a SQL statement for Execute SQL task, drive precedence constraints, set package properties as connection string for example and more. Nested IF-ELSE Statements in a SSIS Expression Ah-ha! Thanks so much! I hadn't thought about doing it that way and yet this is a issue I've run into several times

This seems rather inefficent to me and as a result my question is that do you think that grouping these statements under blanket if clauses will actually speed up the stored procedure? I really want to do this but it would be hard to justify the work and risk if it really won't help at all.All you optimizers out there, would love some input
