Just one day before working on some questions and facing this error. As soon as I get this, I realized that what I hurt and what I had to solve. The suggestion shown in the error message is at the point and precise. We learn to correct error 217 for implicit conversion. Here is the complete error I received when I used an ISNULL function to its value and in case of null value, I wanted to display the time of the current date. Msg 257, Level 16, Status 3, Line 2 The implicit conversion from the datatime to int type is not allowed. Use the CONVERT function to execute this query. -- CREATE TABLE #TestTable (ItemID INT, IsAvailable INT) -- Enter the INSERT table in #TestTable (ItemID, IsAvailable) SELECT 1, NULL UNION ALL SELECT 2, 1 UNION ALL SELECT 3, 1 UNION ALL SELECT 4, NULL UNION ALL SELECT 5, 1 GO Now we run by following the T-SQL script that should launch an error for us. -- Following will throw SELECT ItemID error, ISNULL(Available, GETDATE()))) Available now from #TestTable GO Above T-SQL script will give the following error:Msg 257, Level 16, Status 3, Line 2 The implied conversion of datatime to int is not permitted. Use the CONVERT function to execute this query. Now we can overcome the above error using the following three working methods. Solution / Workaround: -- Fix 1 SELECT ItemID, ISNULL(CONVERT (DATETIME, IsAvailable), GETDATE())) Now available from #TestTable GO -- Fix 2 SELECT ItemID, COALESCE(IsAvailable, GETDATE())) However, there is a small problem here. When I use ISNULL or COALSECE the value IsAvailable which is INT is now converted to the date and display value of the year 1900. Now you can see even if we found workaround has a small problem ? this is better than the mistake we were getting before, but still not exact. Here is the last solution that will overcome the problem of the incorrect data described above. -- Fix 4 SELECT ItemID, CASE WHEN IsAvailable IS NULL THEN CONVERT(VARCHAR(26), GETDATE())))) ELSE CONVERT(VARCHAR(26), IsAvailable) END Available # Now, from # Testino # Here is the screenshot of the result. Well, let me know if there's a better solution and I'll gladly include it here with the credit. Run the following command to clean. -- clean DROP table #TestTable GO Reference: Pinal Dave ( ) SQL SQL The server can implicitly launch strings in the form of 'YYYYYMMDD' to a datetime - all other strings must be explicitly cast. here are two quick code blocks that will convert from the module you are talking about: version 1 uses units variables: BEGIN DECLARE @input VARCHAR(8), @mon CHAR(2), @day char(2), @year char(4), @output DATETIME SET @input = '10022009' --today' SELECT @mon = LEFT it is necessary to convert to char first because the conversion to int adds those days to 1900-01-01-01-01 select CONVERT (datetime,convert(char(8),rnwl_efctv_dt)) here are some examples select CONVERT (datetime,5) 1900-01-06 00:00:00.000 select CONVERT (datetime,2010010101010101) jumps up, because you can not add 2010010101 days to 1900-01-01-01. you go over the limit convert to char before declaring @i int select @i = 2010010101 select CONVERT (datetime,convert(char(8),@i)) From: Tim Ford | Updated: 2019-05-24 | Comments| Related: 1 | 2 | 3 | 4 | 5 | More> Date problem I have a metadata repository developed internally for sql server i i instances One of the metrics that I track is based on the success and failure of the SQL Server Agent Job History. This information comes directly from msdb..sysjobhistory table that resides on each instance of SQL Server. The problem is that there are idiosyncrasies with this table when it comes to store dates and times of job executions. I have to be able to use this information in reports and queries, but these columns are stored in a data format that is not standard, considering the fact that we are discussing the system tables is beating me. Solution Before you start let's look at what we have to do as far as the format of run_date and RUN_TIME fields. Although this tip relates simply to convert the run_date in a useful format, we will convert at a later date RUN_TIME tip. SELECT SJ. [Name], SJH. [Run_date], SJH. [RUN_TIME] DA msdb.dbo. SJH INNER JOIN [msdb] .dbo. SJ ON SJH. [Job_id] = SJ. [Job_id] Where's SJH. [Step_id] = 0 ORDER FOR SJ. The above query returns the following results: As you can see, run_date is stored in the YYYYYMMDD format. It is stored as an integer format, not as a string as is the root underlying format datatime the type of data within Microsoft SQL Server. I suspect it will be only a matter of time before the msdb database receive the same treatment that the master database has made with regard to the logical migration of system tables in the system catalog views, which back the dynamic management visions. Ultimately, The Dynamic management views that address the working structures and backup along with their history and associated configurations stored in the MSDB database make it a perfect target for the eventual expansion of DMV; anyway I digress. Back to the issue at hand. What happens if we use this information in one of the many system functions in SQL Server that are based on a data parameter. I refer to such functions as DATEADD (), DATEDIFF (), DATENAME (), or DATEPART () for example. Why ? do not choose one and make a shot: SELECT SJ. [Name], MAX (SJH. [Run_date])) AS [last_run_date], MAX (DATEDIFF (dd, SJH. [Run_date], GETDATE ()))) )) FROM Msdb.dbo. SJH INNER JOIN [msdb] .dbo. SJ ON SJH. [Job_id] = SJ. [Job_id] Where's SJH. [Step_id] = 0 [name] FROM SJ GROUP. ORDER BY SJ. [Name] The above query returns the following error: Msg 8115, LEVEL 16, State 2, Line 1 Arithmetic overflow error converting expression in datatime datatype . It encounters an error, of course, because ? you are trying to pass an integer data type parameter is provided where a datatime parameter; a classic square peg, round hole situation. How do we address it? A CAST and CONVERT in most phases should do the trick. SELECT SJ. [Name], MAX (SJH. [Run_date]) AS [last_run_date], MAX (DATEDIFF (dd, CONVERT (datetime, CAST (SJH. [Run_date] AS CHAR (8)), 101), GETDATE () ))) FROM Msdb.dbo. SJH INNER JOIN [msdb] .dbo. SJ ON SJH. [Job_id] = SJ. [Job_id] Where's SJH. [Step_id] = 0 [name] FROM GROUP SJ. [Name] ORDER BY SJ. Now we see how to make it work; It takes a moment and briefly break down the components of this conversion: CAST (SJH. [run_date] AS CHAR (8)) - what is around the issue that will continue to meet if we tried to pass the raw integer value for the field [run_date] in the CONVERT () function. CONVERT (datatime, parameter, 101) - The CONVERT () function can be used to modify the way in which the standard datetime format is presented to end users in a query or report. The function includes a final format; in this case you want to use the datatime; an initial value; and a format specifier. The size in our example converts the input values in the format of MM / DD / YYYYY. Please refer to Microsoft SQL Server Online for all available output formats. This process can be made even easier by wrapping this code into a user-defined function. By doing so, you will be able to (a) minimize the amount ofnecessary to achieve the task at hand and (b) create a reusable process: use vocational training udf_convert_int_date (@date_in int) returns datetime as begin declare @date_out datetime set @date_out = convert (datetime, cast (@date_in as char ( 8)), 101) Return @Date_out Fine would then proceed to use this function as you would any other system (integrated) SQL Server function. Below are two examples of such calls. The first is a simple call of this new function created. Returns the distinct results of the raw Run_Date field from msdb.dbo.sysjobhistory and the corresponding converted value: select distinct sjh. [run_date], master.dbo.udf_convert_int_date (SJH. [RUN_DATE] AS [convert_run_date] from msdb.dbo. [SYSJOBHISTORY] SJ The second example is used instead of the code previously supplied in this tip. It is used to calculate the quantity of days since the last execution of an SQL Server Agent Job. Use the function within another function to make the activity at your fingertips: Select SJ. [Name], Max (SJH. [RUN_DATE]) AS [LAST_RUN_DATE], MAX (DATEDIF (DD, MASTER.DBO .udf_convert_int_date (SJH. [RUN_DATE]), GetDate ())))))) by msdb.dbo. SJH Inner Join [MSDB] .Dbo. SJ ON SJH. [Job_ID] = SJ. [Job_id] where SJH is. [STEP_ID] = 0 Group from SJ. [Name] Order from SJ. [Name] Check these additional advice from . Tim Ford is a senior database administrator with Mindbody. View all my suggestions Article Last update 2019-05-24 Summary: In this tutorial you will learn how to convert a datatime into a date using the convert (), try_convert (), and cast () functions. To convert a date to a date, you can use the Convert (), try_convert (), or cast () function. Convert the date to today using the Convert () function this statement uses the Convert () function to convert a date to a date: Convert (Date, DateTime_Expression) Code Language: SQL (Structured Query Language) (SQL) in this syntax, The datatime_expression is any valid expression that evaluates a valid datetime value. The convert function () will alzere an error if the conversion fails. The following example uses the Convert () function to convert a date to a date: Select Convert (Date, GetDate ())) Date; Language code: SQL (Structured Query Language) (SQL) here is the output: Date 2019-04-23 (1 Riga concerned) Code language: SQL (Structured Query Language) (SQL) Note that the GetDate function () Return the current database server date time. Convert Date to date using the try_convert () function the same way, the try_convert () can also be used to convert the date time to a date: try_convert (date, datetime_expression) code language: sql (structured query language) ( SQL) Unlike the Convert () function, the TRY_CONVERT () function returns NULL if the conversion fails. This example uses the TRY_CONVERT () function to convert the current date time to a date: TRY_CONVERT (DATE, GETDATE ()); Code Language: SQL (Structured Query Language) (SQL) The following shows the output: Date 2019-04-23 (1 Riga concerned) Code Language: SQL (Structured Query Language) (SQL) Convert the date to today using the CAST FUNCTION () The following statement converts a value of dateTime to a date using the Cast () function: Cast (DATETIME_EXPRESSION AS DATE) Language code: SQL (Structured Query Language) (SQL) This example uses the Cast () function to convert The current date time in a date value: Cast Select (GetDate () As Date) Date; Language code: SQL (Structured Query Language) (SQL) The output is as follows: Date 2019-04-23 (1 Riga concerned) Code Language: SQL (Structured Query Language) (SQL) in this tutorial, you have learned To use how to convert a date to a date using the Convert () functions, and CAST(). CAST().
