Unable to convert MySQL date/time value to System.DateTime in VS2010

Question

when I want to load data from my mysql database I always get this error:

Unable to convert MySQL date/time value to System.DateTime

This is my connectionstring:

<add name="gdmwebsiteEntities" 
     connectionString="metadata=res://*/Models.DBModel.csdl|res://*/Models.DBModel.ssdl|res://*/Models.DBModel.msl;provider=MySql.Data.MySqlClient;provider connection string=&quot;server=localhost;User Id=root;database=gdmwebsite&quot;" 
     providerName="System.Data.EntityClient" />

I've already added "Convert Zero Datetime=True" add the end of my connectionstring but nothing changed.

    <add name="gdmwebsiteEntities" 
     connectionString="metadata=res://*/Models.DBModel.csdl|res://*/Models.DBModel.ssdl|res://*/Models.DBModel.msl;provider=MySql.Data.MySqlClient;provider connection string=&quot;server=localhost;User Id=root;database=gdmwebsite&quot;
     Convert Zero Datetime=True
      Allow Zero Datetime=True"
     providerName="System.Data.EntityClient" />

Is there another method for fixing this?

Answer 1

Set both of these configurations in your connection string.

"Convert Zero Datetime=True"
"Allow Zero Datetime=True"

Please check manual under connect options and set "Allow Zero Datetime" to true, as on attached pictures, and the error will go away.

To fix this problem, either replace all invalid timestamps with NULL or a valid timestamp, or add Allow Zero Datetime=true
