Why Does Entity Framework Create Plural Table Names While My View Expects Singular Names in MySQL?

Entity Framework Creates Plural Table Name, but View Expects Singular Table Name

Using MySQL .NET Connector 6.4.4.0 and Entity Framework 4.1, developers may encounter an issue where Entity Framework creates a table with a plural name, but the view for the object expects a singular table name. This can result in errors when trying to display the view.

Error Details

The error typically occurs with the following exception:

Table 'mydb.vote' doesn't exist

This exception is thrown when the view attempts to access a table named "vote" when Entity Framework has created the table with the name "votes" (assuming the entity class is named "Vote").

Cause

The cause of this error is related to the Entity Framework convention for pluralizing table names. By default, Entity Framework will pluralize the name of the entity class when generating the table name. However, certain external factors, such as the MySQL .NET Connector's support for Entity Framework, can affect this behavior.

Solution

To resolve this issue, several steps can be taken:

1. Ensure 'DropDatabaseIfExists' or 'DropCreateDatabaseAlways' is used: The ApplicationStart method should set the database initializer correctly.
2. Remove the singular/plural discrepancy from the database: This can be achieved by removing the PluralizingTableNameConvention or by calling ToTable("Votes") in OnModelCreating.
3. Ensure the database exists before running the application: The MySQL .NET Connector may not create the database automatically, so creating the database manually may be necessary.

By following these steps, the discrepancy between the plural table name created by Entity Framework and the singular table name expected by the view can be resolved.
