References to SQL cursor names

A cursor name can only be referenced within the compound statement in which it is declared, including any compound statements that are nested within that compound statement.

The name of an SQL cursor can be the same as the name of another SQL cursor that is declared in the same routine or advanced trigger. This can occur when the two SQL cursors are declared in different compound statements. The compound statement that contains the declaration of an SQL cursor determines the scope of that cursor name. A cursor name must be unique within the compound statement in which it is declared, excluding any declarations in compound statements that are nested within that compound statement. A cursor name can only be referenced within the compound statement in which it is declared, including any compound statements that are nested within that compound statement. When there is a reference to a cursor name, the cursor that is declared in the innermost compound statement is the cursor that is used. See compound-statement for additional information.
