If there is a possibility of this we would need to use REPLACE first otherwise we will get an error. NB: In some countries, for example France where I leave, it is standard practise to use a comma instead of a point. If the datatype is TEXT we have to first cast to varchar(for example) and then cast again to money. SQL server will not convert directly from TEXT to money. Stop storing dates as strings (and maybe even try to get the CSV to contain more reliable literal formats, like YYYYMMDD).We have to use cast or convert, this works directly for datatype CHAR, VARCHAR, NCHAR and NVARCHAR. They should be stored as dates because you get automatic validation, all of the date/time functionality, etc. All that said, these formats can be completely controlled by the client application (C# has very powerful formatting functions), and shouldn't dictate how you actually store the data in the database. Output formats like are much clearer and less prone to misinterpretation even better would be July 8th, 2009 - but then that opens the door to folks using a different language. I still question whether it is actually useful to display as ambiguous formats like - for that date specifically it's clearly September 25th, but are you sure your entire audience will always get correctly? While I'm in the USA that's July 8th, but last week I was in Canada, and I would expect that to be August 7th. When you want to display the date, then format it at the display/presentation layer, but store it correctly in the database. This also doesn't handle validation (like the other answer, it will choke on values like 252525). SELECT may need to do things a little differently if you could have 250999 etc, then you would need some way to indicate whether that's 1999 or 2099, for example. Likewise when displaying the DATE as you desire, you need to use STYLE 3Īnother approach is to cast it directly to a date in SQL Server 2008 or above, then store it that way as commented above. (I am sure that there are other workarounds and conversion styles that would work as well.) To get your DATE formatted in the way you want it, you have to insert the '/' delimiters then use the STYLE 3 in converting from the string to the DATE. The results of the last two selects are: DefaultFormat 1 Since you are not shared the sample data of the Gradd19 value, I suspect the date value is in the yyyy-dd-mm format, so when trying to convert (month value more than 12) it cause the out-of-range value error. Select the value in default Year-Month-Day SET = Second: Convert using STYLE 3 to get DD/MM/YY interpretation Convert your undelimited string DDMMYY into a DATE Without using the 'T' instead of the space in the datetime string, Sql Server won't recognize it as ISO8601 format. If your sql server is set to use the dateformat dmy then that explains your issue. Using the CONVERT style option 3, you can do the following: DECLARE VARCHAR(10) 4 Answers Sorted by: 9 I checked your profile and saw that you are in the UK. I changed the month to 8 to make it easier to double check. Reviewing the MSDN CONVERT documentation does not show a built-in conversion for your string, but it is easy to work around. (And, of course, I agree with the comments that dates should be stored in DATE data types in the database.) An undelimited string of integers is assumed to be Year-Month-Day order. I understand your problem to be how to successfully convert the string into a DATE value.
