Whether to use UNION or OR in SQL Server Queries - SQL Server Performance
Having said that, there are scenarios, like DataWarehouse ETL, where using UNION ALL and then removing duplicates may be more performant than using UNION. The two internal optimizat6ions are: 1) Put the list is put into a hash table so access is done in one probe 2) Put the list into a tree structure, like a heap sort tree, so it is searched in log2(n) probes
I've been searching for your piece of code for 6 days now, and now my application with master-detail forms successfully works on sqlserverce (changing primary keys). No action should be taken based solely on the contents of this information; instead, readers should consult appropriate health professionals on any matter relating to their health and well-being
This means the specific problem class of: Having a small number of different values which are all captured in the stats and are all documented in the histogram part of the statistics in their own bucket Another object gets added within the range of the existing data Is not getting solved by the new CE either, because the logic applied for out of range values is not applied for values which are in-range of the statistics. In opposite to a compilation of executables where we talk about binary compilation, the compilation of a SQL Statement is limited to figuring out the most efficient access to the data requested
DTS used to be able to handle this perfectly well and so did the Microsoft ISAM Jet driver (importing with SQL Sever 2000, SQL Server 7, MS Access or MS Excel up to v.2007 works). i need to find difference for uniqueID in Hours between two dates(where most of the time two dates can be the same date or different), and am using DATEDIFF function
Everything SQL Server Compact: Comparison of SQL Server Compact, SQLite, SQL Server Express and LocalDB
But first I have to fix this dataset errors, so could you please give me an example how to load a table from a SDF file without using a dataset or Entity model? Thanks.

SQL Server UPDATE STATISTICS - SQL Server Performance
If you find that the statistics for one or more of our tables is not accurate enough for your needs, you may need to schedule running the UPDATE STATISTICS command at regular intervals using an appropriate sampling level. For example, you can create statistics for columns in a composite index other than the first column (which is the default for AUTO CREATE STATISTICS), and for columns that are not indexed
This is a great example thanks for the time it took to put it together! I tried your example and got this error when reading from SQL there was an error parsing the query. Thanks Reply Jim Heath Says: July 10, 2011 at 8:45 am This is very useful! I am building an app for my archery club to track events and archers scores and awards
Can I, silly, silly dummy, ask you two my noooooob questions? 1) Why this siiiiiiiimply SQL-query not working with MySQL? SELECT * FROM 'Table 1' 2) What is the main advantage of the databases on text files? Main

ADO.NET Entity Framework and SQL Server CE 3.5
From the example, you can see that the ADO.NET Entity Data Model is a powerful addition to Visual Studio that allows quick and efficient access to SQL Server CE databases. Developer, operations and IT teams must be able to collect and analyze data in real-time if they which to resolve issues quickly without creating additional problems
IF table exists, DROP TABLE then CREATE TABLE - script not working
The script is designed to be run as a whole whether or not the customer has run it before.The purpose of the script is not to rename the column, but rather to build the necessary objects.
