TO_CHAR¶
TO_CHAR(COLUMN_EXPRESSION)
Casts the input to a string value. If the input is a boolean, it will be cast to 'true' if it is true and 'false' if it is false. If the input is NULL, the output will be NULL.
Example:
We are given table1 with columns a and b and c
Note that if the input is a TIMESTAMP_TZ the only currently supported output
format that includes TZH or TZM is YYYY-MM-DD HH:MM:SS.SSSSSSSSS +TZH:TZM
(where + represents + or -). Formats that do not include those
identifiers are supported.
