Oracle7 Server SQL Reference

Lexical Conventions

The following lexical conventions for issuing SQL statements apply specifically to Oracle's implementation of SQL, but are generally acceptable in all other SQL implementations.

When you issue a SQL statement, you can include one or more tabs, carriage returns, spaces, or comments anywhere a space occurs within the definition of the command. Thus, Oracle7 evaluates the following two statements in the same manner:

SELECT ENAME,SAL*12,MONTHS_BETWEEN(HIREDATE,SYSDATE) FROM EMP

SELECT	ENAME,
			SAL * 12,
			MONTHS_BETWEEN( HIREDATE, SYSDATE )
	FROM 
		EMP

Case is insignificant in reserved words, keywords, identifiers and parameters. However, case is significant in text literals and quoted names. See the syntax description of 'text' .
