Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.

Data Type

string

Default Value

""

Remarks

This property allows you to define which pseudocolumns the provider exposes as table columns.

To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"

To include all pseudocolumns for all tables use: "*=*"

This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudocolumn unless it's a table column.
