SyntaxThe DbScopeInfo type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | DbScopeInfo | Construct a DbScopeInfo object. |
Methods| Name | Description | |
|---|---|---|
| Clear | Clear the scope fields. |
| Clone | Clone the scopeinfo object. |
| Compile | Compile the For and While Expressions (when any) and store the result in the CodeBlocks. |
Fields| Name | Description | |
|---|---|---|
 | ForBlock | A code block representing the conditional for clause. A for condition is, essentially, a filter that hides rows for which the condition evaluates to FALSE. The string value is provided for storage, while the code block is provided as a parameter for the EvalBlock() method. |
| ForExpression | A string representing the conditional for clause. A for condition is, essentially, a filter that hides rows for which the condition evaluates to FALSE. The string value is provided for storage, while the code block is provided as a parameter for the EvalBlock() method. |
| IgnoreDuplicates | A flag that is TRUE if a process should ignore duplicate key values. |
| IgnoreFilter | A flag that is TRUE if a process should ignore any filter condition imposed on the current work area. |
| IncludeDeleted | A flag that is TRUE if a process should include deleted rows. |
| Last | A flag that is TRUE if the last row of the current scope is required. |
| NextCount | Permits continuation of a process for the next lNext rows, while obeying for and while clauses. |
| RecId | Permits continuation of a process for a single row number, while obeying for and while clauses. |
| Rest | A flag that is TRUE if a process should continue stepping through data from the current work area cursor position until logical end-of-file. |
| WhileBlock | A code block representing the conditional while clause. A while condition permits continuation of a process that steps through rows until the condition evaluates to FALSE. The string value is provided for storage, while the code block is provided as a parameter for the EvalBlock() method. |
| WhileExpression | A string representing the conditional while clause. A while condition permits continuation of a process that steps through rows until the condition evaluates to FALSE. The string value is provided for storage, while the code block is provided as a parameter for the EvalBlock() method. |
