I have a SSRS report using an ODBC connection with MySQL. I have a problem to match the date with the parameters. When I type a date manually in the query it works fine, no problem. But when I use the parameters, it doesn't return anything. One thing I found is that the date data returned is under the format YYYY-MM-DD and the date from parameter is DD/MM/YYYY. I tried CONVERT and STRING_TO_DATE functions of MySQL but no luck. Any clue?
convert the parameter value to a date based on the format sent from the SSRS to match the format you are using in the manual test.
Converting a date in MySQL from string field

Problem
I need to query out a date value for use in some ETL processing. However, the data is stored in MySQL as a VARCHAR column in values like 1/1/19.
What I've tried
A simple CAST(myDateColumn as DATE) fails as I get values like 0001-01-19 returned back.
Question
Am I able to pass a custom date format string into the CAST call somehow to tell it how to parse out the date parts? If not, could a SUBSTRING type of function help here?
As discussed in the comments above, you can use the STR_TO_DATE() function to parse a string into a proper YYYY-MM-DD date.
This is the SQL statement which I taken from debug mode in VB.Net.
SELECT dt_Date as 'Date',
s_Time as 'Time',
s_For as 'For',
s_Categ as 'Category',
s_Count as 'Count',
s_Remarks as 'Remarks'
FROM Entry
WHERE (s_ENo = '22' and dt_date BETWEEN '06-05-16' And '27-05-16')
I am not sure what's wrong with the above statement since everything seems to be fine to my eyes.
Description of the Error Message
Additional information: Conversion failed when converting date and/or
time from character string.
Any suggestions how to solve this riddle?
Instead if string literals, use strongly-typed parameters. In addition to avoiding data type conversion issues on the SQL Server side, parameters:
Avoid the need to format date/time string literals in a particular way
Improve performance by providing execution plan resue
Prevent SQL injection (barring dynamic SQL on the server side)
If you are using MS-SQL server than use following instructions.
The basic solution is that you have to provide date into either mm/DD/YYYY format or in YYYY-MM-DD date format into ms-sql query.
So, before passing date to query convert your date into either mm/DD/YYYY format or in YYYY-MM-DD format.
You have to format your date string to YYYYMMDD or if you know the server date format then format same as server
I'm trying to extract a text date into a date type field and change the format from yyyymmdd to ddmmyyyy in the process. I have set up a simple select statement checking that the dates are valid and if not setting a default date and this worked fine, no bad dates.
SELECT
IIf(isdate(Format(Left([EffectiveDate],10),"dd/mm/yyyy")),Format(Left([EffectiveDate],10),"dd/mm/yyyy"),#01/01/1900#) AS Expr1
FROM Relationships;
But when I embed this exact same select statement in an Update Set Query:
UPDATE Relationships
SET MSDate = IIf(isdate(Format(Left([EffectiveDate],10),"dd/mm/yyyy")),Format(Left([EffectiveDate],10),"dd/mm/yyyy"),#01/01/1900#);
the dates are formed as mmddyyyy and not ddmmyyyy as the select query does.
Interestingly, when I tried to change the format type to "long date"
UPDATE Relationships
SET MSDate = IIf(isdate(Format(Left([EffectiveDate],10),"long date")),Format(Left([EffectiveDate],10),"dd/mm/yyyy"),#01/01/1900#);
I got the default 01/01/1900 result suggesting what was extracted was not a valid date. By the way, just using the query in a Select statement worked just fine.
I can't help thinking that something is happening in the conversion to date type. I even tried to do DateValue on the query but still no joy.
Since you're using Left([EffectiveDate],10), I assume that the text field actually contains yyyy-mm-dd (the ISO format).
You should leave the string in this format (Access understands ISO and US format mm/dd/yyyy best), and convert it with the CDate() function.
UPDATE Relationships
SET MSDate = IIf(IsDate(Left([EffectiveDate],10)),
CDate(Left([EffectiveDate],10)),
#1900-01-01#);
I have DATE type column in a MySQL database table with dates stored in it. I am using the YYYY-MM-DD format when I upload the dates to the database.
When I check the values they are stored in the correct and expected format (2005-01-02), however when I am attempting to read these values with my C++ program I am receiving something like this: 02/01/2005 00:00:00
I don't really understand the reason, I thought in the DATE type only the YYYYMMDD gets stored without the time. The other weird thing is the reformatting I thought YYYY-MM-DD is an accepted format.
Here is my code:
String^ getDateOfBirth = myReader->GetString("player_date_of_birth");
DateOfBirthLabel->Text = getDateOfBirth;
I am using Visual Studio 2013.
Any help would be appreciated.
when i convert or cast string to date ran succesfull my query from t-sql on sql server but when i assign dataset query on reporting service,i take this error.
'Conversion failed when converting datetime from character string.'
It will depend on the regional settings on your server. I guess your reporting services server thinks days and months are in the opposite position from your SQL server.
The easiest way to consistently get dates to convert from string properly without having to consider regional settings is to use military date format: YYYY-MM-DD
Military format always converts correctly.
Make sure you are not forgetting to put the braces on the "parameter value" field when editing parameters on the DataSet Properties window:
This gives the conversion error:
Parameter Name Parameter Value
#queryDateParameter #reportDateParameter
Correct is:
Parameter Name Parameter Value
#queryDateParameter [#reportDateParameter]
I've had the same issue when trying to pass parameters through SSRS.
when the parameter types are text, SSRS does a conversion using server region settings, in which case, a MM/DD/YYYY and DD/MM/YYYY difference resulted in this error.
Solution for me was to change the parameter type to datetime. This enforces the conversion to be handled correctly.
