Declares an INTERVAL MONTH value in an expression.

where:

 

Syntax element …

Specifies …

sign

an optional minus sign to indicate a negative interval. The default is a positive interval.

The sign must be outside the apostrophes enclosing string.

string

one to four digits representing months. Spaces and new line characters are not allowed between the apostrophes.

Note: Only digits within the apostrophes are parsed and converted to numeric. For example, '1.05' is treated as '105'.

INTERVAL MONTH literals are partly ANSI SQL:2011 compliant.

The ANSI definition places the optional sign for the interval within the apostrophes; the Teradata implementation places the optional sign outside the apostrophes.

INTERVAL MONTH

For details on the INTERVAL MONTH type, see “INTERVAL MONTH Data Type” on page 155.

This example adds an interval of six months to the current system date. (For this example, assume the current system date is 1999-11-03.)

   SELECT (INTERVAL '6' MONTH) + CURRENT_DATE;
 
     ( 6+Date)
   -----------
    2000/05/03
