In the most SQL dialects the double dash (--) can be used instead. Esoteric languages Many esoteric programming languages follow the convention that any text not executed by the instruction pointer (e.g., Befunge ) or otherwise assigned a meaning (e.g., Brainfuck ), is considered a "comment".
TIME: for time values (e.g. 15:51:36). TIME WITH TIME ZONE: the same as TIME, but including details about the time zone in question. TIMESTAMP: This is a DATE and a TIME put together in one variable (e.g. 2011-05-03 15:51:36.123456). TIMESTAMP WITH TIME ZONE: the same as TIMESTAMP, but including details about the time zone in question.
Comments are delimited by /* and */. [20] A standard SAS program typically entails the definition of data, the creation of a data set, and the performance of procedures such as analysis on that data set. [18] SAS scripts have the .sas extension. A simple example of SAS code is the following
SAS introduced new features through dot-releases. From 6.06 to 6.09, a user interface based on the Windows paradigm was introduced and support for SQL was added. [39] Version 7 introduced the Output Delivery System (ODS) and an improved text editor. Subsequent releases improved upon the ODS. For example, more output options were added in version 8.
Set operations in SQL is a type of operations which allow the results of multiple queries to be combined into a single result set. [1] Set operators in SQL include UNION, INTERSECT, and EXCEPT, which mathematically correspond to the concepts of union, intersection and set difference.
A stylistic depiction of values inside of a so-named comma-separated values (CSV) text file. The commas (shown in red) are used as field delimiters. A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams.
Time period definitions use two standard table columns as the start and end of a named time period, with closed set-open set semantics. This provides compatibility with existing data models, application code, and tools
A delimited text file is a text file used to store data, in which each line represents a single book, company, or other thing, and each line has fields separated by the delimiter. [3] Compared to the kind of flat file that uses spaces to force every field to the same width, a delimited file has the advantage of allowing field values of any length.
