MySQL DATE is one of the five temporal data types used for managing date values. MySQL uses yyyy-mm-dd format for storing a date value. This format is fixed. Returns the current date and time as a value in ' YYYY-MM-DD hh:mm:ss ' or YYYYMMDDhhmmss format, depending on whether the function is used in string or numeric. YEAR() function in MySQL is used to find year from the given date. If the date is NULL, the YEAR() function will return NULL. Otherwise, it.

See Section 9. For complete information regarding syntax and additional examples, see the description of the CAST function. In some cases, this syntax can be deceiving. For example, a value such as '' might look like a time value because of the : , but is interpreted as the year '' if used in date context.

The value '' is converted to '' because '45' is not a valid month. The only delimiter recognized between a date and time part and a fractional seconds part is the decimal point. The server requires that month and day values be valid, and not merely in the range 1 to 12 and 1 to 31, respectively. With strict mode disabled, invalid dates such as '' are converted to '' and a warning is generated.

With strict mode enabled, invalid dates generate an error. See Section 5. Dates containing 2-digit year values are ambiguous because the century is unknown. MySQL interprets 2-digit year values using these rules:. Year values in the range become See also Section Numeric Type Attributes. Out-of-Range and Overflow Handling. Date and Time Data Type Syntax. Fractional Seconds in Time Values. Conversion Between Date and Time Types. The Geometry Class Hierarchy.

GeometryCollection Class. MultiLineString Class. Supported Spatial Data Formats. Geometry Well-Formedness and Validity. Functions that expect date values usually accept datetime values and ignore the time part. Functions that expect time values usually accept datetime values and ignore the date part.

Functions that return the current date or time each are evaluated only once per query at the start of query execution. This means that multiple references to a function such as NOW within a single query always produce the same result. For our purposes, a single query also includes a call to a stored program stored routine, trigger, or event and all subprograms called by that program. See Section 5.

Functions that extract parts of dates typically work with incomplete dates and thus can return 0 when you might otherwise expect a nonzero value. For example:. Other functions expect complete dates and return NULL for incomplete dates. These include functions that perform date arithmetic or that map parts of dates to names. Functions that take temporal arguments accept values with fractional seconds. Return values from temporal functions include fractional seconds as appropriate.

When invoked with the days form of the second argument, MySQL treats it as an integer number of days to be added to expr. Beginning with MySQL 8. If the first argument is a dynamic parameter such as in a prepared statement , the return type is TIME.

Otherwise, the resolved type of the function is derived from the resolved type of the first argument. Time zones are specified as described in Section 5. This function returns NULL if the arguments are invalid. On bit platforms, beginning with MySQL 8. For instructions, see Section 5. Returns the current time as a value in 'hh:mm:ss' or hhmmss format, depending on whether the function is used in string or numeric context.

The value is expressed in the session time zone. If the fsp argument is given to specify a fractional seconds precision from 0 to 6, the return value includes a fractional seconds part of that many digits. DATE expr. Extracts the date part of the date or datetime expression expr.

Only the date parts of the values are used in the calculation. These functions perform date arithmetic. The date argument specifies the starting date or datetime value. For more information about temporal interval syntax, including a full list of unit specifiers, the expected form of the expr argument for each unit value, and rules for operand interpretation in temporal arithmetic, see Temporal Intervals.

MySQL 8. In MySQL 8. Bug Formats the date value according to the format string. The specifiers shown in the following table may be used in the format string. Ranges for the month and day specifiers begin with zero due to the fact that MySQL permits the storing of incomplete dates such as ''. The mode affects how week numbering occurs. DAY date. Returns the name of the weekday for date.

Returns the day of the month for date , in the range 1 to 31 , or 0 for dates such as '' or '' that have a zero day part. These index values correspond to the ODBC standard. Returns the day of the year for date , in the range 1 to For information on the unit argument, see Temporal Intervals.

It is not intended for use with values that precede the advent of the Gregorian calendar The value returned is expressed using the session time zone. Clients can set the session time zone as described in Section 5. On bit platforms running MySQL 8. Returns a format string. HOUR time. Returns the hour for time. The range of the return value is 0 to 23 for time-of-day values.

Takes a date or datetime value and returns the corresponding value for the last day of the month. Returns NULL if the argument is invalid. Returns a date, given year and day-of-year values. Returns a time value calculated from the hour , minute , and second arguments. The second argument can have a fractional part.

Returns the microseconds from the time or datetime expression expr as a number in the range from 0 to Returns the minute for time , in the range 0 to MONTH date. Returns the month for date , in the range 1 to 12 for January to December, or 0 for dates such as '' or '' that have a zero month part.

Returns the full name of the month for date. NOW [ fsp ]. NOW returns a constant time that indicates the time at which the statement began to execute. Within a stored function or trigger, NOW returns the time at which the function or triggering statement began to execute. Setting the timestamp to a nonzero value causes each subsequent invocation of NOW to return that value.

Setting the timestamp to zero cancels this effect so that NOW once again returns the current date and time. The period argument P is not a date value. Returns the number of months between periods P1 and P2. Note that the period arguments P1 and P2 are not date values. Returns the quarter of the year for date , in the range 1 to 4. Returns the second for time , in the range 0 to Returns the seconds argument, converted to hours, minutes, and seconds, as a TIME value.

The range of the result is constrained to that of the TIME data type. A warning occurs if the argument corresponds to a value outside that range. It takes a string str and a format string format. The server scans str attempting to match format to it. Literal characters in format must match literally in str. Format specifiers in format must match a date or time part in str. Scanning starts at the beginning of str and fails if format is found not to match. Extra characters at the end of str are ignored.

Unspecified date or time parts have a value of 0, so incompletely specified values in str produce a result with some or all parts set to Range checking on the parts of date values is as described in Section To convert a year-week to a date, you should also specify the weekday:.

The second form enables the use of an integer value for days. In such cases, it is interpreted as the number of days to be subtracted from the date or datetime expression expr. Resolution of this function's return type is performed as it is for the ADDTIME function; see the description of that function for more information. This differs from the behavior for NOW , which returns a constant time that indicates the time at which the statement began to execute.

If that is a problem, you can use row-based logging. This works if the option is used on both the replication source server and the replica. TIME expr.

I'm not advocating this method by any means. I was simply answering the original question given the information that was available. Sometimes data comes in various forms and it's harder to work with than one would have the luxury of if they could mandate the format of the data. While it seemed impossible at first simply trying to use one table, adding the table of dates or even a temp table made it a lot easier.

The only other issue I can think of that might arise would be a shift going over a daylight savings time change, which would add or subtract an hour, which this method does not account for. After quite the bit of hacking away at it, I came to the answer below which I am presenting in case anyone runs into a similar issue in future. I would like to thank everyone who took the time to help, I found the variety of answers quite helpful and I guess I will list my findings below.

The above query returns the following data which is what the desired outcome was. Since the table is set in UTC and the time being checked is then converted by C on the business logic, this is sufficient to bypass any issues which may arise via daylight savings for such computations.

I had not posted what I had so far because I don't think it's headed in the right direction, nor did I really intend for others to write my code for me : However, since you asked, there it is. Thanks, that gets all the dates available, but it does not add the proper days to the results, it simply iterates between the current date and the current date - 1 -- the reason the where clause was there initially and the reason I said I did not feel I was headed the right direction is because I was attempting to use the current date as a pin point to get the dates around it.

The query works well for only today and yesterday, but not for the rest of the week. It looks like this is a weekly schedule of work shifts. The overnight shifts would certainly stand out more clearly. Show 5 more comments. Sorted by: Reset to default. Highest score default Date modified newest first Date created oldest first.

Update I'm not advocating this method by any means. Improve this answer. That's quite the query. Thanks I will study this and see if it brings any benefit over the query demonstrated on what I put under 'Second Edit' on the question. I think what I ended up with is quite a bit simpler but I would welcome any comments on why this is a better option than what I have?

Just tried it, you're absolutely right.
