Important

TO_CHAR’s format string may contain characters that are not format specifiers. These characters appear as literals in the resulting string.

Examples

The following examples use the :> operator to cast a string to a DATE, TIMESTAMP, or similar type. TO_CHAR then converts the casted type to a string.

Important

When you call TO_CHAR and don’t explicitly type-cast the first argument, TO_CHAR will implicitly type-cast the first argument to TIMESTAMP(6).

When you call TO_CHAR and specify a temporal-type column in the first argument, no typecast is needed.
