SmartSQL For REALbasic Download

Description:

SmartSQL is a class created by FreeVBCode.com. We've found this class extremely useful in Visual Basic so we decided to port it to REALbasic.

Overview

The SmartSQL class is designed to simplify the generation of SQL statements. In projects that require the use of complex SQL statements, developers sometimes have to use (often convoluted) if-then or select logic to concatenate and generate the statement. The SmartSQL class eases this process by allowing the developer to use properties and functions to set up the statement, instead of keeping track of a long string.

The class offers flexibility in terms of how to generate the statement. For example, the field list of a select statement can be specified by repeatedly calling the AddField method or by passing a list of field names as a paramarray or array to the AddFields method.

The class offers the ability to easily re-use aspects of a previously generated statement. For instance, the class allows a developer to easily modify the where clause of a previously generated SQL statement, while maintaining the table list, field list, join clause and/or order clause.

An Simple Example:

dim oSQL as new cSmartSQL

oSQL.SetupJoin "Customers", "ID", "Orders", "CustomerID", eClauseOp.Equal, eJoinType.Left

oSQL.AddFields "Customers.Name", "Customers.Phone", "Orders.ID", "Orders.ShippingAddress"

oSQL.AddSimpleWhereClause "Total", 1000, "Orders", eClauseOp.GreaterThan

oSQL.AddSimpleWhereClause "Customers.State", "CA"

MsgBox oSQL.SQL

The message box in the above example will display the following:

SELECT Customers.Name,Customers.Phone,Orders.ID,Orders.ShippingAddress
FROM (Customers LEFT JOIN Orders ON Customers.ID = Orders.CustomerID)
WHERE (Orders.Total > 1000) AND (Customers.State = 'CA');
