SELECTĥ467.12 Example 2 – Specified Format with Decimals This example converts a simple string to a number value. These examples all use the DUAL table, which is a table in Oracle that allows you to display data in a SELECT statement without needing to create or select from a table in your database. I find that examples are the best way for me to learn about code, even with the explanation above. Here are some examples of the TO_NUMBER function. dg represents two characters, which are single-byte characters, used for the decimal marker and thousands group marker.territory is a text expression that identifies the territory whose ISO currency symbol is used.symbol represents the local currency symbol and must be less than or equal to 10 characters.The expression for this parameter can contain one or more of the following parameters, separated by commas: The expression added here will represent the thousand group marker, decimal marker, and the currency symbols to be used. It works similar to the TO_CHAR function but has a few differences. This parameter is used to add extra information to the function in order for the value to be displayed.

If the format mask is not specified, it uses the period character (.) as the decimal place and doesn’t recognise any other symbol. Returns the hexadecimal value of the specified number of digits. Indicates the position of the decimal point (.)Īdds a group separator (often a comma) in a positionĭisplays the value using scientific notationĭisplays the Text Minimum in TM9(the default) or TME (Scientific notation)ĭisplays in the specified position the Euro (or other) dual currency symbol.ĭisplays the value multiplied by 10 n, where n is the number of 9’s after the letter V. Indicate sign of the number with angle brackets ()ĭisplays the number in Roman numerals (upper or lower case) ![]() Include both positive (+) and negative (-) signs Indicates that the format should suppress all leading and trailing blanksĬhanges the ‘0’ format and replace leading 0’s with blank spaces. Includes a leading hyphen (-) for negative numbers. The possible values for number formats you can use are: Format The Oracle TO_NUMBER format mask for this function must be a number format.
