It > takes a string str and a format string format. STR_TO_DATE() returns a > DATETIME value if the format string contains both date and time parts, or a > DATE or TIME value if the string contains only date or time parts. If the > date, time, or datetime value extracted from str is illegal, STR_TO_DATE() > returns NULL and produces a warning. > * Syntax: > STR_TO_DATE(str,format) > * Arguments > **str: - > **format: - > * Return Types > DATAETIME/DATE/TIME > * Example: > STR_TO_DATE('01,5,2013','%d,%m,%Y') -> '2013-05-01' > SELECT STR_TO_DATE('a09:30:17','a%h:%i:%s') -> '09:30:17' > * See more: > ** [MySQL| > https://dev.mysql.com/doc/refman/5.7/en/date-and-time-functions.html#function_str-to-date] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
