 1. Create select `what`, where clause, order clause, `Offset` and `Limit`.
 2. Check clauses' related columns are valid. Then generate sql string and param list.
-3. Convert param list to `Dapper` dynamic params. Execute sql and get `dynamic`s.
-4. Run hook `AfterSelect` for every column.
+3. Convert param list to `Dapper` dynamic params with proper type conversion in `IColumnTypeInfo`. Execute sql and get `dynamic`s.
+4. For each column:
+    1. If column not in query result is null, null will be used to call hooks.
+    2. If column is `NULL`, `DbNullValue` will be used to call hooks.
+    3. Otherwise run conversion in `IColumnTypeInfo`.
+    4. Run hook `AfterSelect` for every column.
 5. Convert `dynamic`s to `TEntity`s.
 
 ### Insert
 
 1. Create insert clause consisting of insert items.
 2. Check clauses' related columns are valid. Then generate sql string and param list.
-3. Run hook `BeforeInsert` for every column.
-4. Convert param list to `Dapper` dynamic params. Execute sql and return `KeyColumn` value.
+3. For each column:
+    1. If insert item exits and value is not null but the column `IsGenerated` is true, throw exception.
+    2. If insert item does not exist or value is `null` for that column, use default value generator to generate value. However, `DbNullValue` always means use `NULL` for that column.
+    3. Coerce null to `DbNullValue`.
+    4. Run hook `BeforeInsert`.
+    5. Coerce null to `DbNullValue`.
+    6. Run validator.
+4. Convert param list to `Dapper` dynamic params with proper type conversion in `IColumnTypeInfo`. Execute sql and return `KeyColumn` value.
 
 ### Update

+    3. Run validator if `value` is not null.
