ORA-13530: invalid TOPNSQL string, must be in the range (string, string)
Cause: The TOPNSQL string given was not in the valid range of parameters expected by the TOPNSQL function.
Action: The TOPNSQL function expects two arguments, the first being the SQL text in a given format and the second argument being the TOP blocks which must be in the range of 0 to 2^32-1. Check the syntax of the statement and ensure that the arguments are correct.
一个常见的ORA-13530错误案例是:当用户创建数据库表时,指定TOPN(n值)超出了有效的范围。
1. 首先检查应用程序的TOPN字符串,确保它的值在有效范围内(0至2^32-1)。
2. 如果是由于应用程序指定的TOPN值过大,则可能需要重新设计出数据库表,以减少TOPN的大小。
3. 检查TOPNSQL字符串,确保它遵循有效的语法格式。
4. 如果TOPN参数和字符串符合有效的参数,则正常执行TOPNSQL查询。
