Out – usage, meaning; out – what is meaning.
Different databases use different datatype names. When choosing a variable length datatype for a datatype it’s preferably in a different format than the usual one for string datatypes. For variable-length strings, VARCHAR(n) or TEXT(n) are the common names. Figure 3-6 shows variable-length strings on country names (COUNTRY), returned only the names of the countries and no padding out to maximum from fixed-length strings.
How do you understand in last sentence?
What are some of the best ways to get your thesis statement changed?
In addition to the correct answers given already it might be worthwhile seeing an example of padding out string, in a database context.
A variable length string, defined as VARCHAR(10) and populated with Italy would return a string of length 5 containing the characters I T A LY. When treated as an array variable length string would be char A
fixed length string would return a string of length 10 containing the letters I T A L Y _ _ _ _ (where on Stackechange I need to use '_' to denote a space) If an array are treated as strings, the fixed length string would be char.
With data like COLUMBIA the variable length string would be C O L O M B I A and the fixed length string would be C O L O M B I A. _ The
fixed length string has been padded out with spaces at the end to ensure that it always takes up the defined number, in this case 10, of characters.
Many database will allow you to use a function to remove padding spaces. Whether it is to remove padding spaces or not, how do you remove padding spaces?
In both cases the maximum number of characters is adhered to so UNITED KINGDOM would be saved as U N I T E D ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ VARCHAR(max) or similar allows almost any size variable length string to be stored without truncation.
In this case, it means to completion. Another case of “out”: build out—to complete a building project.
Definition 5 applies:
Out : 5. To the end. Everything.
Is it true that VARCHAR does not require strings to be padded with spaces or extra characters as they are variable length?
