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.
A scalar function returns only a single value (or NULL), whereas a table function returns a (relational) table comprising zero or more rows, each row with one or more columns. User-defined functions in SQL are declared using the CREATE FUNCTION statement. For example, a user-defined function that converts Celsius to Fahrenheit (a temperature ...
In a database, a table is a collection of related data organized in table format; consisting of columns and rows.. In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect.

The parameters of a function can be viewed collectively as the fields of a record and passing arguments to the function can be viewed as assigning the input parameters to the record fields. At a low-level, a function call includes an activation record or call frame , that contains the parameters as well as other fields such as local variables ...
In Raku, the assuming method creates a new function with fewer parameters. [4] The Python standard library module functools includes the partial function, allowing positional and named argument bindings, returning a new function. [5] In XQuery, an argument placeholder (?) is used for each non-fixed argument in a partial function application. [6]
Page, which means a segment can only be located at an address that is a multiple of 256, starting from address 0. […] Inpage, which means a segment can be located at whichever of the preceding attributes apply plus must be located so that it does not cross a page boundary […] The alignment codes are: […] B – byte […] W – word […]
Parameters appear in procedure definitions; arguments appear in procedure calls. In the function definition f(x) = x*x the variable x is a parameter; in the function call f(2) the value 2 is the argument of the function. Loosely, a parameter is a type, and an argument is an instance.
Similarly, Nulls are often confused with empty strings. Consider the LENGTH function, which returns the number of characters in a string. When a Null is passed into this function, the function returns Null. This can lead to unexpected results, if users are not well versed in 3-value logic. An example is below:
