I have some dates in a table like this: 23/12/2013 16:34:32 24/12/2013 07:53:44 24/12/2013 09:59:57 24/12/2013 12:57:14 24/12/2013 12:48:49 24/12/2013 13:04:17 24/12/2013 13:15:47 24/12/2013 13:21:02

24/12/2013 14:01:28 24/12/2013 14:02:22 24/12/2013 14:02:51 They are stored as strings unfortunately And I want to convert them to datetime SELECT CONVERT(datetime, analysed, 103 ) FROM OIL_SAMPLE_UPLOAD However I get this message when I run the query The conversion of a varchar data type to a datetime data type resulted in an out-of-range value. Presumably because some values are badly formed (although I am yet to spot any of these) It's ok if some values don't convert, I just need a way of handling this situation. Something like ISNULL(CONVERT(datetime, analysed, 103 )) would be good except that the convert function does not return NULL when it fails. sql string tsql error-handling type-conversion share|improve this question asked Jan 29 '14 at 4:20 sav 7891922 to be clear the strings are in dd/MM/yyyy hh:mm:ss format –sav Jan 29 '14 at 4:31 add a comment| 3 Answers 3 active oldest votes up vote 10 down vote accepted For SQL Server you can use ISDATE() function to check whether value is valid date SELECT CASE WHEN ISDATE(analysed)=1 THEN CONVERT(date

I need something like "tryParse" in C# lang but as SQL statement. More detailed, I need the following statement returns zero or any else but throwing exception. select convert(float, 'fjsdhf') thanks in advance. sql-server tsql exception-handling share|improve this question edited Jun 25 '09 at 9:24 Ed Guiness 26.4k1581127 asked Jun 25 '09 at 9:15 AndrewG 71321019 add a comment| 5 Answers 5 active oldest votes up vote 32 down http://stackoverflow.com/questions/1042816/ms-sql-server-casting-without-exception vote This will default non-numerics to 0 and will not require another statement: SELECT CASE WHEN ISNUMERIC(myvarcharcolumn)=1 THEN CONVERT(float, REPLACE(LTRIM(RTRIM(myvarcharcolumn)), ',', '.')) ELSE 0 END AS myfloatcolumn The REPLACE() function call is used to change commas to periods. Commas are used in some cultures as a decimal separator (e.g., "1,25" instead of "1.25"), but unless your server is set up with one of those as the default culture, ISNUMERIC() will return 1 but CONVERT() will throw an error. This does mean that your strings should not use commas as thousands separators, but in most cases, a comma for a decimal placeholder is more likely to be a decimal placeholder. The LTRIM(RTRIM()) call is because ISNUMERIC() will return 1 for a string with leading or trailing spaces, but CONVERT() can't deal with them. So, you must trim your strings. The only remaining potential issue is that ISNUMERIC() will return 1 if the number can be represented as an int, currency, decimal, or float, but you're only converting to a float. Realistically, a float can store just about anything you throw at it, but if you were trying to convert to an int instead, ISNUMERIC() would return 1 for a value like "2.5", but CONVERT(int, '2.5') will still throw an error. share|improve this answer edited Aug 26 '13 at 6:00 answered Aug 31 '09
