Crystal Reports Command Parameter Conversion to Date Issue (Where Clause)

Former Member — Wed, 18 Dec 2019 08:32:29 GMT

Hi,

I've created a CR with a command that has SQL hitting SQL Server. Start and End date parameters/prompts were also created.

So my command looks basically like this...

Declare @BeginDate AS VARCHAR(100)
Set @BeginDate = '{?BeginDate}'
Declare @EndDate AS VARCHAR(100)
Set @EndDate = '{?EndDate}'
--some manipulation is done on @BeginDate and @EndDate
Eventually @FinalBeginDate and @FinalEndDAte are set to date values via...
set @FinalBeginDate = CAST(@BeginDate as DATE)
set @FinalEndDate = CAST(@EndDate as DATE)

Then a SELECT is run returning many fields include PERIOD which is a VARCHAR(6) defined field containing year and month values in the format YYYYMM.

I want my WHERE clause to have something like this...

SELECT...WHERE CAST(PERIOD + '10' AS DATE) >= @FinalBeginDate and CAST(PERIOD + '10' AS DATE) <= @FinalEndDate

I consistently get this error...

Failed to retrieve data from the database.

Details 22007:[Microsoft][SQL Server Native Client 11.0][SQL Server]Conversion failed when converting date and/or time from charactrer string. [Database Vendor Code: 241]

NOTE: If I leave out the WHERE condition I'm trying to create and display @FinalBeginDate and @FinalEndDate the output is 12/1/2019 and 12/31/2019. And if I display the PERIOD it is 201912.

I have attempted tons of variations of this line:

CAST(PERIOD + '10' AS DATE) >= @FinalBeginDate and CAST(PERIOD + '10' AS DATE) <= @FinalEndDate

using CONVERT, CAST, etc. on PERIOD, @FinalBeginDate and @FinalEndDate but I can't get around the error.

Anyone have any suggestions?

Thanks

Hi Michael,

Is there any place where PERIOD is null? If so, that might be causing your error and you'll have to account for that.

Also, I might look at this the other way around. Instead of trying to cast the PERIOD as a date, I might reformat the final begin and end dates as strings in YYYYMM format. It would look something like this:

IsNull(PERIOD, '000000') >= left(Convert(varchar, @FinalBeginDate, 112), 6) and 
IsNull(PERIOD, '000000') <= left(Convert(varchar, @FinalEndDate, 112), 6)
