Remarks

The SelectStatement class is designed for easy manipulation of SQL SELECT statements. It allows you to perform the following tasks:

  • Construct SELECT statements in run time;
  • Modify the statements with object-oriented interface;
  • Parse the statements from strings.
The SelectStatement class exposes SELECT, ORDER BY and GROUP BY clauses as collections of SelectColumn objects (SelectColumnCollection), and FROM clause as collection of SelectTable objects (SelectTableCollection). The WHERE and HAVING clauses are represented as string expressions.

To obtain the statement text use the ToString method.

Instances of this class cannot be created directly. To use its functionality, one needs to create an object of a descendant class, like PgSqlSelectStatement.
