The field of the value type in 1.Model is changed to a nullable type. Specific settings: Tools-Options-Code Parameters-field type mapping [Isvaluetype] segment;
If you don't, you can delete the corresponding fields in the configuration file.
2. Batch code generation, table name unified go to prefix function
3. Code generator Add code Save function
4. Added efficient connection mode: Enable this for fast connection in case of a large number of tables.
5. Added support for MySQL database.
6. Query Analyzer Right-click Add-on function: Generate SQL script splicing code directly from SQL statement, which provides more flexible data layer code generation.
7. Query Analyzer Right-click additional functionality: Generate Data scripts based on SQL query results instead of data scripts for the entire table.
8. Based on the SQL Method dal code generation, add method to increase the value of the field null insertion judgment
9. BLL Add public list<> getmodellist () method to return list<> data.
10. Record error log information.
11. Publish the BLL Layer Code template component source.
12. Publish the Web layer code generation component source.
13. Release model code generation component source
