FlexScript Class - Database.ResultSet

Database.ResultSet

Description

A class for retrieving the result of a database SQL query.

A Database.ResultSet is returned by Database.Connection.query(), and by Database.PreparedStatement.execute(). The class provides methods and properties for retrieving the result data associated with a SQL query execution.

Database.Connection con = Database.Connection("DBConnector1");
con.connect();
Database.ResultSet result = con.query("SELECT * FROM customers");
while (result.fetchNext()) {
	string firstName = result["FirstName"];
	string lastName = result["LastName"];
	for (int j = 1; j <= result.numFields; j++) {
		Variant column1Value = result[j];
		...
	}
	...
}
con.disconnect();
	

A Database.ResultSet implements a forward-only cursor. This means you can only traverse through the results once. This can either be done manually, using fetchNext(), or automatically by dumping the data to a table with cloneTo(). However, you cannot do both. In other words, you cannot clone the result using cloneTo(), and then also use fetchNext() to traverse the result again, or vice versa.

Properties

numFields The number of fields in the result set.

Methods

cloneTo Clones the result set to a destination table.
fetchNext Moves the cursor forward one record in the result.
