Usage

using Strata.SqlTools.Breakdowns.SqlServer;

// Parse a T-SQL query
var query = QueryBreakdown.Parse(@"
    SELECT CustomerID, CustomerName
    FROM Customers
    WHERE Region = @region
");

// Parameters are automatically extracted during parsing
Assert.That(query.Parameters, Does.ContainKey("@region"));

// Modify and regenerate - parameters are automatically extracted
query.AddWhereClause("IsActive = 1", "and");
query.AddWhereClause("CreatedDate > @startDate", "and");

// The @startDate parameter is now in the Parameters dictionary
query.SetParameterValue("@startDate", "2024-01-01");
query.SetParameterValue("@region", "West");

string sql = query.GetSql();

Automatic Parameter Extraction

The AddWhereClause method automatically extracts @parameter references and adds them to the Parameters dictionary:

Parameters are created with null values initially
Use SetParameterValue to assign actual values
Existing parameter values are preserved when adding additional WHERE clauses
Type mismatches throw InvalidOperationException for safety
