Reserved Keywords

Here are the reserved keywords for Embedded SQL for C (ESQL/C). Keywords reserved for Transact-SQL are also reserved for ESQL/C. The application can use these keywords in string literals in SQL statements if the literal is enclosed in single quotes.

Reserved Keywords

Microsoft® SQL Server™ 2000 uses reserved keywords for defining, manipulating, and accessing databases. Reserved keywords are part of the grammar of the Transact-SQL language 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, this can be done only using delimited identifiers.

The following table lists SQL Server reserved keywords.

In addition, the SQL-92 standard defines a list of reserved keywords. Avoid using SQL-92 reserved keywords for object names and identifiers. The ODBC reserved keyword list (shown below) is the same as the SQL-92 reserved keyword list.

 

Note The SQL-92 reserved keywords list sometimes can be more restrictive than SQL Server and at other times less restrictive. For example, the SQL-92 reserved keywords list contains INT, which SQL Server does not need to distinguish 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. The use of reserved keywords as the names of variables and stored procedure parameters is not restricted. For more information, see Using Identifiers.

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. For more information, see Microsoft ODBC 3.0 Programmer's Reference, Volume 2, Appendix C.
