References to SQL statement names

The name of an SQL statement can be the same as the name of another SQL statement declared in the same routine or advanced trigger.

This can occur when the two SQL statements are declared in different compound statements. The compound statement that contains the declaration of an SQL statement name determines the scope of that statement name. A statement 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 statement 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 statement name, the statement that is declared in the innermost compound statement is the statement that is used.
