Oracle TRUNC Date Function By Practical Example

Die Oracle/PLSQL TRUNC-FOR-DATE-Funktion gibt ein Datum zurück, das auf eine bestimmte Maßeinheit gekürzt wurde In Oracle, TRUNC(datetime, unit) function allows you to truncate a datetime value to the specified unit (set zero time, set the first day of the month i.e).In SQL Server, you can use various expressions using CONVERT function to get the same result..

ROUND and TRUNC Date Functions Table 5-14 lists the format models you can use with the ROUND and TRUNC date functions and the units to which they round and truncate dates. The default model, 'DD', returns the date rounded or truncated to the day with a time of midnight. Table 5-14 Date Format Models for the ROUND and TRUNC Date Function The TRUNC function has the signature:. TRUNC( date_value, format ) You are providing a string value instead of a date value and 'dd-mm-yy' is an invalid format (you just want to truncate to the start of the day using 'dd' as the format or the start of the month using 'mm' or the start of the year using 'yy' - but using all three together does not make sense) The purpose of the Oracle TRUNC function is to truncate either a number or a date value. The TRUNC function works on two different data types - number or date. This means you can provide it with either of these two data types, and the TRUNC function will perform slightly differently and give you a result for that data type
