to-date

问题 I have a problem and I can't solve it yet. On my database I have the string: TO_DATE(' 2015-03-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'). So when I'm building my query it is like the following: Select my_field FROM my_table. the result is: TO_DATE(' 2015-03-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN') Get it? How to I extract the value of this field as a command statement on a select query? 回答1: On the sqlplus command line, if your system supports

问题 I have an insert query: INSERT INTO THE_TABLE (Field_A) VALUES (TO_DATE('08/12/2011 08:35:42 AM','HH:MI:SS PM')) WHERE Something = 'SomethingElse' Field_A is a Date field. When I execute the query, Field_A still shows a date and time. Is there a way to grab only the time? I have tried To_Char(), but then it converts to a string and the field wont take it. I have also tried TO_DATE('08:35:42 AM','HH:MI:SS PM') and that doesn't work either, it still shows a date and time in the table. 回答1: If

How can I ignore the .mmm characters for importing them into a DATE column? I cannot seem to find an answer to this; I get that DATE columns don't hold milliseconds, but why can't I ignore specific patterns in the TO_DATE call?

问题 This question already has answers here : How to store only time; not date and time? (5 answers) Closed 5 years ago . I would like to insert data to db as time, not date. If I use to_date('2012-08-31 07:39:33', 'YYYY-MM-DD HH24:MI:SS') it adds date too.

问题 I have a field in a table that can be informed with differente values. Examples: Row 1 - (2012,2013) Row 2 - 8871 Row 3 - 01/04/2012 Row 4 - 'NULL' I have to identify the rows that have a string with a date mask 'dd/mm/yyyy' informed. Like Row 3, so I may add a TO_DATE function to it. Any idea on how can I search a mask within the field? Thanks a lot 回答1: Sounds like a data model problem (storing a date in a string). But, since it happens and we sometimes can't control or change things, I
