- The main idea started from: jOOQ, typedquery
- Useful library to make
typed-safequery to database, currently supportPostgreSQLandMSSQL. - UI tool to generate mapped class from database.
- Use
CooQwith existing ORM project, the only thing need to do is generate classes and make query with syntax as below.
- Already work with ADO.NET
-
Currently supports 2 database types -
MSSQLandPostgreSQL. I use velocity to generate class by template. - You can extend as you want. -
To generate template, you should open file
CooQGenerate.exethen fill specific required information to connect to your database, then click Generate button. -
Init
CooQwith Connection String -
You must init some information for
CooQonce.
//for PostgreSQl
CooQ.Query.Init(new CooQ.ConnectionSetting()
{
Server = "localhost",
Database = "database_name",
Username = "postgres",
Password = "root",
Port = 5432,
Type = CooQ.Types.DatabaseType.POSTGRESQL
});//for MSSQL
CooQ.Query.Init(new CooQ.ConnectionSetting()
{
Server = @".\SQLEXPRESS",
Database = "database_name",
Type = CooQ.Types.DatabaseType.MSSQL
});- Make Query. Note that your database naming convention should be lowercase with _, for example your table name is TableTest then it should be table_test in your database.
Suppose you create a table in your database named table_test and your generated class is:
//we have 2 mapped class after generated:
Table.TableTest.cs
Record.TableTestRecord.cs
Supposed that table_test have 2 columns named column_a, column_b.//We have two mapped columns after generated:
TableTest.TABLETEST.COLUMNA
TableTest.TABLETEST.COLUMNB
Then, you make a first query as below:- Select Query
IQueryable<Record> res = CooQ.Query.Select(TableTest.TABLETEST)
.From(TableTest.TABLETEST)
.Execute()
.GetRows();
foreach (TableTestRecord record in res)
{
//your code here...
Debug.Print("Column A is:" + record.ColumnA);
}- Insert Query
Query.Insert(TableTest.TABLETEST)
.Set(TableTest.TABLETEST.COLUMNA, "value 1")
.Set(TableTest.TABLETEST.COLUMNB, "value 2");- Update Query
Query.Update(TableTest.TABLETEST)
.Set(TableTest.TABLETEST.COLUMNA, "value 1")
.Set(TableTest.TABLETEST.COLUMNB, "value 2");- Delete Query
Query.Delete(TableTest.TABLETEST)
.Where(TableTest.TABLETEST.COLUMNA = "value 1");This article, along with any associated source code and files, is licensed under The MIT License
