with anchoring functions are assigned at the beginning of the stored procedure call. When the anchor of a declare statement is based on a cursor object, the data type of the variable is obtained when the variable declaration statement is executed. The data type is only anchored once, and then no longer changes. If a variable in ROW TYPE OF a cursor is defined in a loop, the data type is acquired at the beginning of the loop, and the subsequent loop no longer changes.Example: Create table T
