Calculating Tree Cost in Microsoft SQL Server - CodeProject

Finally, we get a fully calculated tree structure as shown in the below image: Final cost for node 5 (E) can be seen in above figure as 106.69 which is calculated from its children. Using CTE approach to deal with such structures is popular, however, this handcrafted traversal of the structure makes it lightweight and cost effective

Microsoft SQL Server - Lesson 05: Introduction to the Columns of a Table

To change your mind, click Cancel To delete a column using code, first open or access an empty Query Editor, and use the following formula: ALTER TABLE TableName DROP COLUMN ColumnName On the right side of the ALTER TABLE expression, type the name of the table. If you anticipate a column to hold decimal values, specify its data type as numeric or decimal (either decimal or numeric would produce the same effect in Microsoft SQL Server)

Microsoft SQL Server - Lesson 04: Introduction to the Tables of a Database

In reality, if a table belongs to a schema other than dbo, you should always precede its name with its schema You can type the name of the database to which the table belongs, followed by the period operator, followed by the schema, followed by the period operator, and followed by the name of the table. The table would open in design view, the same view you use to visually create a table In our lessons, if you right-click a table in the Object Explorer and click Design, the window that displays will be referred to as the Design View of a table

This doesn't take care of circumstances where another table has a foreign key to the table you want to drop - in that case, you'll want to explicity drop that foreign key first

DELETE is not a DML-operation which support bulk logging and if a table does not have constraints which prevents a TRUNCATE than the following workload seems to be the best by consideration of bulk logged operations: Separate the data which should not be deleted by using SELECT ... Use of TRUNCATE instead of DELETE for the deletion of records The usage of TRUNCATE instead of DELETE seems to be inviting, because TRUNCATE does not log the deletion of each record

I changed the @sql to @sqlTables in the drop code so I could run the drop constraints and drop tables in the query (it was complaining about declaring @sql twice).

In such a situation, we have two alternatives: Truncate Table In this solution, we can insert the remaining data into a temporary table, truncate the original and finally insert data back in from the temporary table

There is a SQLBulkCopy object available in .NET to send multiple rows of data to SQL Server at once, but this still cannot be passed to a stored procedure. Instead of worrying about the hardware and deployment issues around applications, one can focus on building the solution and using the enterprise quality cloud platforms which previously didn't exist or were prohibitively expensive and difficult to use

EXEC CleanUpSchema 'MySchema', 't' -- debug GO EXEC CleanupSchema 'MySchema', 'w' -- work for me These are the known limitations of the script It can not drop a PK table in the schema with an XML index or Spatial index defined It can not drop the schema which is referred by a XML schema collection Please let me know if you find any more issues with the script. Are there any particular terms for doing this? thanks, Peter Hussey LabKey Software (and former SQL Server group program manager) Reply Ranjith said: May 31, 2011 at 5:03 pm Hi Peter, Thanks for asking and I am glad to hear that its useful to you guys
