Program Considerations
• DATE
• TIME
• TIMESTAMP
• INTERVAL
For example, they can be used in CREATE TABLE statements and in INSERT statements.
However, some restrictions may apply when ANSI/SQL DateTime data types are used.
In the FIELD command, the ANSI/SQL DateTime data types must be converted to fixedlength
CHAR(10) data types. See section “Using ANSI/SQL DateTime Data Types” on
page 138 for a description of the fixed-length CHAR representations for each ANSI/SQL
DateTime data types.
Comments
Teradata TPump supports C language style comments. A comment begins with a slash asterisk
“/*” and all subsequent input is treated as a comment until a terminating asterisk slash “*/” is
encountered. Comments may nest and they do not occur within string or character literals.
For an example, a “/*” within a quoted string is not treated as the beginning of a comment.
Comments are written to the message destination. Substitution of values for variable names
continues within comments. If the variable name is required, two “&”s should be coded. Note
that recursive comments are permitted, which means that to end the comment, the number of
terminating “*/” sequences must match the number of start “/*” comment sequences that are
outstanding.
Comments can be optionally sent to Teradata Database. If a comment is used together with a
Teradata SQL statement, a semicolon may be placed as a terminating character to end the
comment. The semicolon tells Teradata TPump to strip out the comment so that it is not sent
to Teradata Database. If a semicolon is not used, the comment is sent to Teradata Database
together with the Teradata SQL statement.
Nested comments are supported when they occur before or after Teradata SQL statements.
Nested comments within Teradata SQL statements are not supported. Nested comments must
terminate with a semicolon. If a semicolon is not appended, the comment is erroneously sent
to Teradata Database and a syntax error is returned.
Specify a Character Set
Table 16 describes ways to either specify the character set or accept a default specification.
