What is the difference between dd/mm/ yy and dd/mm/rrrr




















If FM is omitted, then the month is blank-padded to nine characters:. The following statement places a single quotation mark in the return value by using a date format model that includes two consecutive single quotation marks:. Two consecutive single quotation marks can be used for the same purpose within a character literal in a format model.

You can use a format model to specify the format for Oracle to use to return values from the database to you. Because of this format model, Oracle returns salaries with leading dollar signs, commas every three digits, and two decimal places. With this format model, Oracle returns the hire dates without blank padding as specified by fm , two digits for the day, and the century included in the year.

When you insert or update a column value, the datatype of the value that you specify must correspond to the column datatype of the column. You can use format models to specify the format of a value that you are converting from one datatype to another datatype required for a column. For example, a value that you insert into a DATE column must be a value of the DATE datatype or a character string in the default date format Oracle implicitly converts character strings in the default date format to the DATE datatype.

You must also use a format model to specify the format of the character string. The following additional formatting rules apply when converting string values to date values unless you have used the FX or FXFM modifiers in the format model to control exact format checking :.

You can omit punctuation included in the format string from the date string if all the digits of the numerical format elements, including leading zeros, are specified. If a match fails between a datetime format element and the corresponding characters in the date string, then Oracle attempts alternative format elements, as shown in Table Table Oracle Format Matching.

Table lists and describes the attributes of the XMLFormat object. The function that implements this type follows the table. Format Models A format model is a character literal that describes the format of datetime or numeric data stored in a character string. Number Format Elements A number format model is composed of one or more number format elements. You can specify multiple commas in a number format model. Restrictions: A comma element cannot begin a number format model. A comma cannot appear to the right of a decimal character or period in a number format model.

Restriction: You can specify only one period in a number format model. Returns trailing zeros. B B Returns blanks for the integer part of a fixed-point number when the integer part is zero regardless of zeros in the format model. The default is a period. EEEE 9. You can specify multiple group separators in a number format model. MI MI Returns negative value with a trailing minus sign -. Returns positive value with a trailing blank.

Returns positive value with a leading and trailing blank. Returns a value as Roman numerals in lowercase. Value can be an integer between 1 and S S S Returns negative value with a leading minus sign -. Returns negative value with a trailing minus sign -. TM TM The text minimum number format model returns in decimal output the smallest number of characters possible.

This element is case insensitive. Restrictions: You cannot precede this element with any other element. V V99 Returns a value multiplied by 10 n and if necessary, round it up , where n is the number of 9's after the V. If the specified number is not an integer, then Oracle Database rounds it to an integer. Restrictions: This element accepts only positive values or 0. Negative values return an error.
