SQL Server ODBC driver for Windows users can now use the Named Pipes connection protocol. This allows you to use the driver in SQL Server deployments where TCP/IP connections have been turned off or to take advantage of performance improvements in environments where Named Pipes is a more efficie...
IN the SQL database system, the CONCAT is replaced by ‘||’, which is the string concatenation symbol. The concatenation symbol is suitable with any SQL standards but this will not work perfectly in all database systems. For example, you need to make use of the operator “+” in the ...
New string functions are CONCAT_WS, TRANSLATE, and TRIM, and WITHIN GROUP is now supported for the STRING_AGG function. (CTP 1.1) There are new bulk access options (BULK INSERT and OPENROWSET(BULK...) ) for CSV and Azure Blob files. (CTP 1.1) Memory-optimized object enhancements include...
The two most common types of blind SQL injection attacks are the Boolean Attack and the Time-based Attack. In a Boolean attack, the attacker expects a different response if the query is True than if it is False. For example, the results might get updated if the query is valid, but stay...

SQL .selectFrom(tUser) .columns( tUser.firstName.as("username2"), COUNT(tUser.firstName).as("count") ) .where(tUser.isMan.eq(1)) .groupBy(tUser.firstName) .havingF((r) => [r.count.compare(">", 1)]) // Via argument 'r' you can access properties defined in columns. .ord...
Here is where I will keep logs of what I am learning! Welcome to "SQL-Learning" For Data Analysis! In this Git repo, I'll embark on a SQL learning adventure to become a SQL master. Over the next couple of weeks, I'll dive into the world of databases, queires, and data manipulati...
Some new functions (eg. CONCAT) work as soon as you migrate to 2012 and leave compat mode at 100. But other functions (eg. PERCENTILE_CONT) need to have compat mode at 110 in order to work. Is there a list somewhere of what new functions work simply by upgrading to SQL 2012, and ...
// CypherMath.Add if ( lhsIsListValue && rhs instanceof ListValue ) { return VirtualValues.concat( (ListValue) lhs, (ListValue) rhs ); } // VirtualValues.concat public static ListValue concat( ListValue... lists ) { return new ListValue.ConcatList( lists ); } 这样会有15000个Concat...
