Special reserved words are

In this article Applies to: Microsoft SQL Server uses reserved keywords for defining, manipulating, and accessing databases. Reserved keywords are part of the grammar of the Transact-SQL language that is used by SQL Server to parse and understand Transact-SQL statements and batches. Although it is syntactically possible to use SQL Server reserved keywords as identifiers and object names in Transact-SQL scripts, you can do this only by using delimited identifiers. The following table lists SQL Server and Azure Synapse Analytics reserved keywords. Note The ISO standards reserved keywords list sometimes can be more restrictive than SQL Server and at other times less restrictive. For example, the ISO reserved keywords list contains INT. SQL Server does not have to distinguish this as a reserved keyword. Transact-SQL reserved keywords can be used as identifiers or names of databases or database objects, such as tables, columns, views, and so on. Use either quoted identifiers or delimited identifiers. Using reserved keywords as the names of variables and stored procedure parameters is not restricted. ODBC Reserved Keywords The following words are reserved for use in ODBC function calls. These words do not constrain the minimum SQL grammar; however, to ensure compatibility with drivers that support the core SQL grammar, applications should avoid using these keywords. This is the current list of ODBC reserved keywords.

The following list includes all words reserved by the Microsoft Access database engine for use in SQL statements. The words in the list that are not in all uppercase letters are also reserved by other applications. Consequently, the individual Help topics for these words provide general descriptions that do not focus on SQL usage. Note: Words followed by an asterisk (*) are reserved but currently have no meaning in the context of a Microsoft Access SQL statement (for example, Level and TableID). Words that are not underlined do not have linked explanations.

From There is no time bash builtin. time is a keyword so you can do for instance time " because " time is a keyword"? Keywords, reserved words, and builtins are all the "first word" of a simple command. They can be placed in two groups: Keywords and builtins. The two are mutually exclusive. A word (token) can be either a keyword or a builtin, but not both. Why the "first word" From the A "simple command" is a sequence of optional variable assignments and redirections, in any sequence, optionally followed by words and redirections, terminated by a control operator. 2.- The words that are not variable assignments or redirections shall be expanded. If any fields remain following their expansion, the first field shall be considered the command name and remaining fields are the arguments for the command. After that "first word" has been identified, and after is has been expanded (by an alias, for example) the final word is "the command", there could be only one command in each line. That command word could be a builtin or a keyword. Keyword Yes, a keyword is a "reserved word". Load "man bash" and search for keyword or just execute this command: LESS=+/'keyword' man bash. The first hit on search says this: keyword Shell reserved words. It happens in the completion section, but is quite clear. Reserved words In POSIX, there is But the Bash manual has a better working definition. Search for "RESERVED WORDS" ( LESS=+/'RESERVED WORDS' man bash) and find this: RESERVED WORDS Reserved...

Python reserved words list |List of Keywords in Python Reserved Words:- In this tutorial, you will learn about Python reserved words list (List of Keywords in Python) and ... If you want to have an overview, here is the complete list of all the keywords. Keywords are called as the reserved words in python used to perform the operations. All the keywords in python are in lower case. The value of the reserved keywords is fixed and cannot be changed. We cannot use keyword as variable name, function name. They have special meaning and are used for special purpose only. Python 3 has 33 keywords while Python 2 has 30. To get the keywords list on your operating system, open command prompt and type “Python” and hit enter. Then type help () and hit enter. Now type keywords to get list for current python version running on your Os. Below is the list of reserved Keywords in python programming:- About Class This class will include the hands-on guide to object-oriented programming language working with a database.

"Reserved words" are words and symbols that have a specific meaning to Microsoft Access. If you use a reserved word or symbol to name a field in a desktop database or web app table, Access warns you that the word is reserved and that you might encounter errors when referring to the field. You might also encounter errors if you use a reserved word to name a control, an object, or a variable. The error messages you receive don't necessarily tell you that a reserved word is the cause of the problem. As a result, it can be difficult to identify what needs to be changed. For example, Access might display a message similar to the following: The wizard was unable to preview your report, possibly because a table needed by your report is exclusively locked. If a reserved word is already in use, you can avoid error messages by surrounding each occurrence of the word with brackets ([ ]). However, the best solution is to change the name to a nonreserved word. Note: It is not practical to provide a list of all reserved words, such as built-in function names or user-defined names. If you set a reference to a type library, an object library, or an ActiveX control, that library's reserved words are also reserved words in your database.
