active-query-builder-3-net-dml-generator

This repository demonstrates how to generate INSERT, UPDATE and DELETE statements for a given SELECT query. It uses the API of the Active Query Builder for .NET v.3 to analyze the query.

There are 2 main entities:

  • ISqlSyntaxOverride - interface to describe SQL syntax and database client specific features. There are 2 implementations of this inteface in the demo: CommonSqlSyntaxOverride - for base features and MsSqlSyntaxOverride - for the standard MS SQL Sever client library (System.Data.SqlClient). You can add other overrides by analogy.
  • DmlSqlGenerator - the DML statements generator itself.

Usage:

var dmlGen = new DmlSqlGenerator(queryBuilder1, new MsSqlSyntaxOverride());
MessageBox.Show(dmlGen.GenerateInsertSql(), "Insert");
MessageBox.Show(dmlGen.GenerateAllFieldsUpdateSql(), "All fields update");
MessageBox.Show(dmlGen.GenerateSingleFieldUpdateSql(), "Single field update");
MessageBox.Show(dmlGen.GenerateDeleteSql(), "Delete");
