This restriction applied even when the called SQL was a PL/SQL anonymous block. Through Oracle Database 11 g Release 2 (11.2), when PL/SQL invoked SQL, only values with data types supported by SQL could be bound. It relieves the application developers from the burden of formulating their queries in terms of views or LEFT OUTER JOIN syntax.Ģ.1.4.12 PL/SQL-Specific Data Types Allowed Across the PL/SQL-to-SQL Interface These views are merged in a heuristic manner without having to go through cost-based query transformation. Merging of such views allows more join reordering and, therefore, more optimal execution plans. Such views can originate from the user query or they may be generated during conversion from LEFT OUTER JOIN syntax. Merging of multiple table views on the left hand side of an outer join. This expansion provides the following benefits: In Oracle Database 12 c, the native syntax for a LEFT OUTER JOIN has been expanded to allow multiple tables on the left hand side. The only way to execute such a query was to translate it into ANSI syntax. Prior to Oracle Database 12 c, having multiple tables on the left hand side of an outer join was illegal and resulted in an ORA-01417 error. Beginning with Oracle Database 12 c, a single table can be the null-generated table for multiple tables. In previous releases of Oracle Database, in a query that performed outer joins of more than two pairs of tables, a single table could be the null-generated table for only one other table. coffee files anywhere:ĬoffeeScript on the top left, compiled JavaScript output on the bottom right.2.1.4.3 Enhanced Oracle Native LEFT OUTER JOIN Syntax Latest Version: 2.7.0 # Install locally for a project: The compiled output is readable, pretty-printed, and tends to run as fast or faster than the equivalent handwritten JavaScript. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart.
