MySQL vs PostgreSQL - WikiVS
The default configuration for both is tuned to run on small systems, and it's common for people performing benchmark tests to either not change the defaults, or properly tune only the one they are most familiar with. A 2009 benchmark for MySQL 5.0.51 and MySQL 5.1.30 with InnoDB 1.0.3 (MySQL 5.4 contains the patches from InnoDB 1.0.3) compared with PostgreSQL 8.3.7 suggested that MySQL and PostgreSQL were almost equal in terms of scalability, by at least one standard of measure
You continue to access the table in the same way as before , while SQL Server internally traverses the local and the remote storage to get the requested data set. Azure SQL Databases provides the ability to restore a database to any point in time, within the retention interval for that service tier or as configured
SQL Injection Attacks by Example
It doesn't stop with backslashes either: there is Unicode, other encodings, and parsing oddities all hiding in the weeds to trip up the application designer. Map out more database structure Though this particular application provided such a rich post-login environment that it didn't really seem necessary to dig further, in other more limited environments this may not have been sufficient

Web SQL Database
(So the first ? placeholder gets bound to the first value in the arguments array, and generally the nth ? placeholder gets bound to the nth value in the arguments array.) Binding the ? placeholders is done at the literal level, not as string concatenations, so this provides a way to dynamically insert parameters into a statement without risk of a SQL injection attack. Treating persistent storage as cookies If users attempt to protect their privacy by clearing cookies without also clearing data stored in the relevant databases, sites can defeat those attempts by using the two features as redundant backup for each other

Depending on your budget splashing out an a decent SAN solution may help - although SAN technology is beyond my current level of experience, I am just someone who uses it while other people configure it. I think many people still forget that computers have moving parts, they are machines - they are not some sort of quantum flux probability engine that returns results at the speed of light

Another alternative which I prefer is actually in the stored proc if you have a helper function that converts a CSV to a table, then you are able to join on that which is much safer than just sending the input directly to the query.

OR GIVE ME A EXAMPLE TO KNOW HOW TO DOTHANK YOU VERY MUCH!! Dave Oct 27, 2009 at 9:50 PM 1 Comments Hi J.D,If you can join ECRPYHS and ECRHDHS, it should be easy to join PAYINFO as well. It doesn't happen all that often (most of my SQL is fairly simple), but every now and then someone shows me something that just rocks my world, whether it be the power of Indexing or just something as simple as using UNION ALL instead of UNION

Now when u delete a record from the master table all other details table record based on the deleting rows primary key value, will be deleted automatically
-- Check the content of the table SELECT * FROM Table1 SELECT * FROM Table2 GO As you can see that using JOIN clause in UPDATE statement it makes it very easy to update data in one table from another table. However, the easiest and the most clean way is to use JOIN clause in the UPDATE statement and use multiple tables in the UPDATE statement and do the task
SQL Server follows ANSI Entry SQL with regard to referential integrity between PrimaryKey and ForeignKey columns which requires the inserting, updating, and deleting of data in related tables to be restricted to values that preserve the integrity. In the response to my reply I was pointed out to my own blog post where user suggested that I had previously mentioned this is possible and with demo example
