- A correlation name must be unique in a FOR iteration statement; however, the same correlation name can be used both for nested and non-nested FOR iteration statements.
- A correlation name can be the same as the FOR loop variable and the names of cursors within a FOR iteration statement.
- Columns and correlation names must be qualified with a FOR loop variable when referenced in SQL statements, including control statement, within the iteration statement.
- If a column or correlation name is not qualified, then column and correlation name references are treated as either parameters or local variables.
- The scope of a FOR iteration statement correlation name is the body of the statement.
