SQL-02124: NULL value returned by EXEC TOOLS statement

SQL-02124: NULL value returned by EXEC TOOLS statement
Cause: A NULL value was returned by EXEC TOOLS for a host variable that lacks an indicator variable. This error is returned only when MODE=ANSI. When MODE=ORACLE, although the value of the host variable is indeterminate, no error is generated.
Action: Associate an indicator variable with each host variable to which nulls might be returned.

SQL-02124：由EXEC TOOLS语句返回的NULL值,
.原因： EXEC TOOLS为缺少指示符变量的主机变量返回NULL值。仅当MODE = ANSI时才返回此错误。当MODE = ORACLE时，尽管主变量的值不确定，但不会生成错误。,
.操作：将指示符变量与可能返回空值的每个主机变量相关联。,
