generator. (1) Data access: The view that comes with the Oracle data contains the field and field comments for the table, we need to correlate the views user_tab_columns and User_col_comments, just select the field name, data type, precision, and comment four fields to be able, table name as the condition parameter. The detailed SQL is as follows: (2) Business realization:
For code generators, complex queries do not provide methods in the data access layer and transactions. Therefore, for actual project applications, I have developed a new data access interface in the framework of Li Tianping.
The IDAL interface is as follows:
IBaseDataHelper
///
/// The public data interface is mainly used for queries, transactions, and other complex data operations.
///
Public interface IBaseDataHelper
{
///
/// Return DataSet using SQL
You can use the "generate SQL script" tool that comes with SQL Server 2000 to generate SQL scripts for creating tables, views, and stored procedures. So can we generate SQL scripts for the data in the table and automatically import the data to SQL Server after executing thes

Refer to the MongoDB input format SQL generator byPHP. In the past few days, refer to the representation of MongoDB input parameter formats such as find ({a: 1, $ or: {c: 1, B: 2, this input method parses the data and outputs an array with the analytical data. in this case, you can refer to the input parameter format of MongoDB in the past few days. find ({a: 1, $ or: {c: 1, B: 2}) indicates that the input

Many years ago used Li Tianping predecessors, their own change, and then the teacher Li did move soft, not to the source code, modification is not very convenient. Plus I need to go to the Java direction now, so I decided to do it myself. So far it has taken one weeks to look at the current results.The last is the code engineering file, developed in C #, the IDE is VS2010To achieve maximum template freedom, a proprietary template syntax is designed. Based on C #, but has been made as simple as p
