[ 1][ 2] SQL injection must exploit a security ...

A stored procedure (also termed prc, proc, storp, sproc, StoPro, StoredProc, StoreProc, sp, or SP) is a subroutine available to applications that access a relational database management system (RDBMS).

Tables can be set to inherit their characteristics from a parent table. Data in child tables will appear to exist in the parent tables, unless data is selected from the parent table using the ONLY keyword, i.e. SELECT * FROM ONLY parent_table;. Adding a column in the parent table will cause that column to appear in the child table.
LizaMoon is a piece of malware that infected thousands of websites beginning in September, 2010. It is an SQL injection attack that spreads scareware encouraging users to install needless and rogue "anti-virus software". [1] Although it does not use new infection techniques, it was initially thought to be notable based on the scale and speed at ...
Prepared statement. In database management systems (DBMS), a prepared statement, parameterized statement, or parameterized query is a feature where the database pre-compiles SQL code and stores the results, separating it from data. Benefits of prepared statements are: [1] efficiency, because they can be used repeatedly without re-compiling.
