C Sql Server And Entity Framework Don T Save Changes Stack Overflow

C Sql Server And Entity Framework Don T Save Changes Stack Overflow I have the following issue: i created a sql server localdb instance and created a simple table called player. then i added an ado entity framework data model (database to code) and instantiated the poco class player. The database might not preserve your changes if your changes affect a precision level that is not supported by the data type of the database field. a common example for this is the datetime field in ms sql server which has less precision than the datetime object in , check the code below.

C Sql Server And Entity Framework Don T Save Changes Stack Overflow My workflow is, pull all the products from the database into the program, (we use c# and ef core), update the relevant products, and send back the updates to the database. Savechangesasync does not save changes made within the context to the database. no error's are noticed. however the changes cannot be seen in the database. i have attached the trace files. steps to reproduce:. My web api code already incorporates the mitigation advised for ef core 8 when working with sql tables that have triggers. the particular error i have having says it cannot cast from system.string data type to system.int64 data type. Trying to implement entity framework for an existing database (sql server 2012). i have a vb application running and trying to convert it to the ef based web api. when i insert data into the table inboundequipment where inboundequipmentid is an identity column.

Just edit the properties in your entitites and save them. if you cannot do this as part of the changes you save, you can just do an extra operation and save it. you could also look into using interceptors in ef. Ef core will cache all entities in the change tracker by default. it doesn't have a two way connection with the database so the cache can become stale if you have other processes touching the data outside of your context. If you are using the repository pattern without entity framework, which is possible, you might find that some data sources (yes, we are back at the data sources) don’t need a savechanges method. I've recently updated a number of apis from core 2.2 to 5.0 and am now experiencing some issues when saving changes back to the database context.
