Name component of a query band specification.

The maximum size for each pair_name is 128 UNICODE characters. For more information about database object names, see Teradata Vantage™ - SQL Fundamentals, B035-1141.

The number of pair_name=pair_value pairs is limited to the maximum length of the string, which is 4,096 UNICODE characters, including pad characters.

You must enclose the set of name=value pairs for the query band with APOSTROPHE characters. If an APOSTROPHE character is embedded within a pair name, you must type it twice, to escape it. Otherwise, the system interprets it as a pair_name=pair_value string terminator.

pair_name cannot contain any of the following characters.

  • EQUALS SIGN (=)
  • SEMICOLON (;)
  • a null
Do not specify reserved pair names. For a list of reserved query band names, see Teradata Vantage™ - SQL Data Definition Language Detailed Topics, B035-1184.
