Note (1): Both function and procedure refer to internal routines written in SQL and/or procedural language like PL/SQL. External routine refers to the one written in the host languages, such as C, Java, Cobol, etc. " Stored procedure " is a commonly used term for these routine types.
Presentation metadata: how the attribute is to be displayed to the user (e.g., as a text box or image of specified dimensions, a pull-down list or a set of radio buttons). When a compound object is composed of multiple attributes, as in the EAV/CR design, there is additional metadata on the order in which the attributes should be presented, and ...
computes the difference in seconds between two time_t values time: returns the current time of the system as a time_t value, number of seconds, (which is usually time since an epoch, typically the Unix epoch). The value of the epoch is operating system dependent; 1900 and 1970 are often used. See RFC 868. clock
Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the ...
[17] The separator used between date values (year, month, week, and day) is the hyphen, while the colon is used as the separator between time values (hours, minutes, and seconds). For example, the 6th day of the 1st month of the year 2009 may be written as "2009-01-06" in the extended format or as "20090106" in the basic format without ambiguity.
In mathematics, a function is a rule that maps elements from an expression to a range of values. Consider the function: times_10(x) = 10 * x. The expression 10 * x is mapped by the function times_10() to a range of values. One value happens to be 20. This occurs when x is 2. So, the application of the function is mathematically written as:
In IF commands and other syntax that has expressions evaluated as conditions, any string value is evaluated as a numeric value and, if that is a nonzero value, then it is interpreted as True. a<b yields 1 if a is less than b, 0 otherwise. Declarations None. All variables are dynamically created at the first time a value is assigned. Lines
Items represent the content of a note. Every item has a name, a type, and may have some flags set. A note can have more than one item with the same name. Item types include Number, Number List, Text, Text List, Date-Time, Date-Time List, and Rich Text. Flags are used for managing attributes associated with the item, such as read or write security.
