This is the format that will be used to convert string1 to a date. When you want, you can place one or more separators between the day and month or between the year and month. The syntax for the TODATE function in Oracle/PLSQL is: TODATE( string1, formatmask, nlslanguage ) Parameters or Arguments string1 The string that will be converted to a date. Although date and time information can be represented in both character and number datatypes, the DATE.
As separators, you can use a space, dash ( -), slash ( /), colon ( :), or comma ( ,). The DATE datatype stores date and time information. When the day and year components are adjacent, they must have at least one separator between them.
For years in the range 1950 to 2049, the year component can, alternatively, have two digits (50 represents 1950, and so on). The day component can have one digit or two digits.įor any year, the year component can have four digits (for example, 1997). The case of the letters in the month component (uppercase or lowercase) does not need to match the case in MONTHNAMES. You can abbreviate the month name to one letter or more, when you supply enough letters to uniquely match the beginning of a name in MONTHNAMES. The month component must match one of the names listed in the MONTHNAMES option. Stores logical values that you can use in logical operations.Specify the day and year as INTEGER values and the month as text, using these rules: Each record in the database has a physical address or rowid.
