Classes | |
class | RWDBAssignment |
Represents the result of applying the RWDBColumn::assign() method to an RWDBExpr. More... | |
class | RWDBBoundExpr |
Acts as a placeholder in a dynamic SQL statement, providing a type-safe interface for binding a local variable to a dynamic SQL statement. More... | |
class | RWDBCollectableExpr |
Adds RWCollectable semantics to RWDBExpr. More... | |

Class RWDBExpr is a base class for a family of classes that allow you to program SQL expressions in C++. Additional classes in this category include RWDBAssignment, RWDBCriterion, RWDBCollectableExpr, RWDBBoundExpr, and RWDBJoinExpr. The DB Interface Module User's Guide contains examples of using these classes.
The DB Interface Module also provides an extensible mechanism for defining SQL expressions for your specific needs. The classes RWDBExprFormDefinition, RWDBExprFuncDef0, RWDBExprFuncDef1, RWDBExprFuncDef2, RWDBExprFuncDef3, RWDBExprFuncDef4, RWDBCritFormDefinition, and RWDBCritFuncDef0, RWDBCritFuncDef1, RWDBCritFuncDef2, RWDBCritFuncDef3, RWDBCritFuncDef4 support this mechanism.
