The default start+increment form with the start value of 1 and increment of 1 is not suitable for all circumstances. There are reasons to choose each form, and trade-offs in doing so. [2] The default start and increment values might reveal information about a table that it is desired not to reveal to people viewing individual table rows.
The post-increment and post-decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to the increment (or decrement) operation. In languages where increment/decrement is not an expression (e.g., Go), only one version is needed (in the case of Go, post operators only).
Nonetheless, for clarity, dictionaries list numerical prefixes in hyphenated form, to distinguish the prefixes from words with the same spellings (such as duo-and duo). Several technical numerical prefixes are not derived from words for numbers. (mega-is not derived from a number word, for example.)
MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [6] is an open-source relational database management system (RDBMS). [6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language.
Since the Leszynski naming convention is a special form of Hungarian notation the same general advantages also apply to the Leszynski convention.. The use of distinctive prefixes makes your database self-documenting; when you see frmSales in VBA code, you will know that it references a form, and when you see curSales you will know that it is a Currency variable.
