T-SQL Restore Script Generator - SQLServerCentral
This might be required following a media failure on the drive hosting the database data files (and assumes current backup history in MSDB), you should always take a tail log backup first if possible before starting to plan restores
One possible optimization with OUTER JOINs is that adding references to the table in the right side of a JOIN to the WHERE clause will convert the OUTER JOIN to an INNER JOIN, just like in the example below: In terms of time, there was an expected difference between both examples (124ms and 144ms respectively) with these small tables, favorable to the INNER JOIN, but that will also depend on the physical JOIN in use. Therefore it is cheaper to get the rows from the larger table and match the ones from the smaller, or to put it in other words, the RIGHT JOIN is cheaper than the LEFT JOIN
If you set the schema name, table name, and desired data compression type in the variable declarations at the top of the script, you will get some pretty detailed information about all of the indexes in that table. You could also wrap part of this in a stored procedure that you could call for each table in a database, and have it write the results out to a table that you could easily query later
SQL Server Forums - Truncate All Tables
Using DELETE statement can increase the size of the log file and hence used the CHECKPOINT statement to clear the log file after every DELETE statement.Imp: You may want to skip CHECKIDENT statement for all tables and manually do it yourself. There are no constraints on the tables because I built the views to pull together what is needed to link to another in house Access database which is where the users want to work with the data
The resulting report generated from the SQL 2012 Upgrade Advisor did not highlight this as something to fix, but this issue was clearly reported on the older SQL 2008 R2 Upgrade Advisor tool. If you simply tried to upgrade the compatibility level and relied on the report alone, you might not have known that your database was no longer functioning correctly
Querying SQL Server 2012: Part II - CodeProject
8.1 CROSS APPLY The CROSS APPLY operator works like an INNER JOIN in that it can match rows from two tables and leaves out rows that were not matched by the other table in the result. The following query gets the top three most expensive orders regardless of customer and as a result each Person is duplicated three times in the result (once for each order, regardless of whether the order was placed by this Person)
SQL Server Tutorials and Tips
Let's take a look at the query as shown below - --CROSS JOIN SELECT ContactName, CompanyName, City, OrderID, OrderDate, RequiredDate FROM Customers CROSS JOIN Orders Summary In this article, we have seen different types of joins you can perform in SQL Server. The query is as shown below - The output of the above query is as shown below - EXCEPT Operator We will now explore the last operator, the EXCEPT operator

To illustrate how to use LookupSet, I want to produce a list of the sales by state and include a count of customers so that I can compare the average sales per customer by state. Of course, if I wanted a list of those customers, I could use the Join function to convert the array that returns from the LookupSet function into a string
If you just want to identify what is causing the data to be deleted - your dba could setup a server-side trace to capture any statements that hit that table.If you want to audit all access, your dba can help you setup auditing (change data capture) - or other options.There are a lot of options available and your dba can help you identify the best solution for your environment
INNER JOIN vs LEFT JOIN performance in SQL Server - Stack Overflow
Don't know if this answers your question but I was once in a project that featured highly complex queries making calculations, which completely messed up the optimizer. (Especially if there are naive users doing ad-hoc queries that do not understand the relational model) The view may include all the relevent columns from many tables
How to use the LEFT JOIN vs. RIGHT OUTER JOIN in SQL
Note For those of you following along with the complete syntax diagrams in Appendix A, SQL Standard Diagrams, note that we've pulled together the applicable parts (from Select Statement, Table Reference, and Joined Table) into simpler diagrams that explain the specific syntax we're discussing. You could also join the second and third tables first (as long as the third table is, in fact, related to the second table and not the first one) and then perform the final JOIN with the first table
