SQLQueryParser Class

The SQLQueryParser class is the main class in the library.

Constructors

  • SQLQueryParser(DbConnection connection): Initializes a new instance of the SQLQueryParser class with a database connection.

Methods

  • List<string> ExtractFieldNames(string sqlQuery): Extracts the field names from a SQL query.

    • Parameters:
      • sqlQuery (string): The SQL query string.
    • Returns:
      • A list of field names.

  • List<string> ExtractTableNames(string sqlQuery): Extracts the table names from a SQL query.

    • Parameters:
      • sqlQuery (string): The SQL query string.
    • Returns:
      • A list of table names.

  • List<string> GetFieldNamesFromQuery(string sqlQuery): Gets the field names from a SQL query, either by extracting them directly from the query or by retrieving them from the metadata based on the table names used in the query.

    • Parameters:
      • sqlQuery (string): The SQL query string.
    • Returns:
      • A list of field names.

Example

using AQueryDisassembler;

// Create a SQLQueryParser instance with a database connection
DbConnection connection = new SqlConnection(connectionString);
SQLQueryParser parser = new SQLQueryParser(connection);

// Example 1: Extract field names from a SQL query
string sqlQuery = "SELECT column1, column2 FROM table1";
List<string> fieldNames = parser.ExtractFieldNames(sqlQuery);
Console.WriteLine("Field Names: " + string.Join(", ", fieldNames));

// Example 2: Extract table names from a SQL query
string sqlQuery2 = "SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.id";
List<string> tableNames = parser.ExtractTableNames(sqlQuery2);
Console.WriteLine("Table Names: " + string.Join(", ", tableNames));

// Example 3: Get field names from a SQL query
string sqlQuery3 = "SELECT * FROM table1";
List<string> fieldNamesFromQuery = parser.GetFieldNamesFromQuery(sqlQuery3);
Console.WriteLine("Field Names from Query: " + string.Join(", ", fieldNamesFromQuery));
