In SQL Server you can use CONVERT function to convert a DATETIME value to a string with the specified style (string format). WHERE B.This can depend on a variety of factors - the operating system's regional settings, the current user's language and dateformat settings. SET = 'SELECT B.FacId, B.FacName, B.BookCode, B.BookName, B.Quantity, B.TillDate AS TILLDATE FROM B Pass the parameters directly in to sp_executeSQL and thus preserve their types e.g.Don't use dynamic SQL at all, maybe doesn't vary that much and you can union them in to a view or something.Thus you can fix it by: SET = 'SELECT B.FacId, B.FacName, B.BookCode, B.BookName, B.Quantity, CONVERT(VARCHAR(10), B.TillDate, 104) AS TILLDATE FROM B WHERE B.TillDate BETWEEN as varchar(15))+', 101) and CONVERT(VARCHAR(10), as varchar(15))+'), 101)' In SQL Server 2012 or later you can use the Format () function to get this result: Select Format (YourColumn, N'yyyyMMddHHmmss') Share. I'd like to see your variable definitions but I suspect it's because and are datetime and you're using them in a string concatenation statement. Doing a convert(,101) is an expensive operation which can better be done using the casting to float and taking floor of that value. The way the date part of the datetime variables is removed is not very optimal.The table name is wrapped in the QUOTENAME() function which protects against sql injection on the object name.Note that TRYCONVERT function is available since.

The 3rd and 4th parameter keep their original datatype and do not need to be converted to a varchar.WHERE B.TillDate BETWEEN as float)) as datetime)ĮXEC sp_executesql datetime, datetime', to note about sp_executesql are: SELECT GETDATE () AS UnconvertedDateTime, CAST (GETDATE () AS nvarchar (30)) AS UsingCast, CONVERT. The following example displays the current date and time, uses CAST to change the current date and time to a character data type, and then uses CONVERT display the date and time in the ISO 8901 format. , CONVERT(VARCHAR(10), B.TillDate, 104) AS TILLDATE Using CAST and CONVERT with datetime data. The best solution is to use a parameterized query with sp_executesql. You should not concatenate your parameter values like this.
