If called with no argument, this function returns a Unix timestamp (seconds since '1970-01-01 00:00:00' UTC) as an unsigned integer. CURRENT_DATE and CURRENT_DATE() are synonyms for CURDATE(). So, I put together a document that shows The CURRENT_DATE is SQL-standard date function supported by almost all database systems such as Firebird, DB2, MySQL 5.x+, MonetDB, Oracle 11.x+, PostgreSQL, and SQLite.. finding what you are looking for much easier. 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 a string or numeric context. Returns the current UTC date and time as a value in 'YYYY-MM-DD HH:MM:SS' or in a YYYYMMDDHHMMSS format, depending on whether the function is used in a string or in a numeric context. BigQuery supports the following DATETIME functions.. All outputs are automatically formatted as per ISO 8601, separating date and time with aT.. CURRENT_DATETIME CURRENT_DATETIME([timezone]) Description. The SUBTIME() function returns expr1 . LOCALTIME and LOCALTIME() are synonyms for NOW(). The calculation and organization should be done within the query. For example set the NLS_DATE_FORMAT to the following format. ADDTIME(expr1,expr2) ADDTIME() adds expr2 to expr1 and returns the result. to common SQL Server date and time functions.

Here is the SQL to do that. If the format is given, the result is formatted according to the format string, which is used in the same way as is listed in the entry for the DATE_FORMAT() function. If the mode argument is omitted, the value of the default_week_format system variable is used. Returns a value in the format YYYYMM. Returns the minute for time, in the range 0 to 59. Extracts the date part of a date or datetime expression, Returns the weekday index of the argument, Returns the last day of the month for the argument, Creates a date from the year and day of year, Returns the number of months between periods, When invoked with three arguments a synonym for DATE_SUB(), Returns the time at which the function executes, Returns the argument converted to seconds, Extracts the time portion of the expression passed, With a single argument this function returns the date or datetime expression. This command formats the date value as per the format string. SQL Server. The date is a DATETIME or DATE value specifying the starting date. This value is expressed in the current time zone. The unit for the result is given by the unit argument. These expr1 and expr2 values are time or date-and-time expressions, but both must be of the same type. The value is expressed in the current time zone. One of the first considerations is the actual date/time needed. Returns the weekday index for date (0 = Monday, 1 = Tuesday, .

In a nutshell, the problem occurs because dates in Google Sheets are actually stored as serial numbers, but the Query function requires a date as a string literal in the format yyyy-mm-dd, otherwise it can’t perform the comparison filter. expr2 expressed as a time value. If the time value contains an hour part that is greater than 23, the %H and %k hour format specifiers produce a value larger than the usual range of 0 to 23. between specified dates as a bigint, DATEADD - returns datepart with added interval as a datetime, EOMONTH – returns last day of month of offset as type of start_date, SWITCHOFFSET - returns date and time offset and time zone offset, TODATETIMEOFFSET - returns date and time with time zone offset, ISDATE – returns int - Returns 1 if a valid datetime type and 0 if Returns the seconds argument, converted to hours, minutes and seconds, as a value in 'HH:MM:SS' or HHMMSS format, depending on whether the function is used in a string or numeric context. For example, DAY and SQL_TSI_DAY both are legal. This converts a datetime value dt from the time zone given by from_tz to the time zone given by to_tz and returns the resulting value.

SQL SELECT DATE is used to retrieve a date from a database. And the Conversation functions are PARSE, TRY_PARSE, CONVERT, and TRY_CONVERT. For information on the INTERVAL unit argument, see the discussion for DATE_ADD(). Returns the integer difference between the date or datetime expressions datetime_expr1 and datetime_expr2. Note: most of these functions will work for Server is running on plus the offset from UTC, SYSUTCDATETIME - returns the date and time of the machine the SQL Server Takes a date or datetime value and returns the corresponding value for the last day of the month.

We use these functions are different dates to return the date in different formats. The STR_TO_DATE() function returns a DATETIME value if the format string contains both date and time parts. The following table shows the expected form of the expr argument for each unit value. Since this is the case, you can use the CAST function to remove the time from the Datetime. This format is fixed and it is not possible to change it. It has the ability to store the month, day, year, century, hours, minutes, and seconds.
