ANSI Compliance

This statement is a Teradata extension to the ANSI SQL:2011 standard.

INTERVAL-to-Fixed CHARACTER Conversion

When the target data type is CHAR(n), then n must be equal to or greater than the length of the canonical form of the value as represented by a character string literal.

If n is greater than that length, trailing pad characters are added to pad the canonical representation.

If n is too small, then a string truncation error is returned.

INTERVAL-to-VARCHAR Conversion

When the target data type is VARCHAR(n), then n must be equal to or greater than the length of the canonical form of the value as represented by a varying character string literal.

If n is too small, then a string truncation error is returned.
