DECLARE testID number(6); testRevID number(6); LDescription varchar2(100):='奥马哈:确保Y-D电路2A压缩机夹具移除测试-4 comp'; BEGIN SELECT tl.TESTID INTO testID FROM TESTLIB tl WHERE tl.DBDESCRIPTION = LDescription; SELECT tlv.testrevid INTO testRevID FROM TESTLIBREVISION tlv 其中tlv.revision = 2和tlv.testid = testID; dbms_output.put_line(testID); dbms_output.put_line(testRevID); END; 当我在SQL Developer中运行查询时,我收到以下错误: 错误报告: ORA-01422:精确提取返回超过请求的行数 ORA-06512:第11行 01422. 00000 - 确切提取返回超过请求的数量行 *原因:精确提取中指定的数量小于返回的行数。 *操作:重写查询或更改请求的行数 任何人都可以告诉我上面的查询有什么问题..感谢任何帮助。 提前致谢。 我尝试了什么: SELECT tlv.testrevid FROM TESTLIBREVISION tlv 其中tlv.revision = 2和tlv.testid = 1604; dbms_output.put_line(testrevid); 但是当我运行上面的脚本时,我得到单值。解决方案 问题肯定只是由于select查询返回了多行。 请检查其他值。只是尝试找到重复的值 DECLARE testID number(6); testRevID number(6); LDescription varchar2(100) := 'Omaha : Ensuring Y-D Circuit 2A compressor Fixture Removed test -4 comp';BEGINSELECT tl.TESTID INTO testID FROM TESTLIB tlWHERE tl.DBDESCRIPTION = LDescription;SELECT tlv.testrevid INTO testRevID FROM TESTLIBREVISION tlvwhere tlv.revision = 2 and tlv.testid = testID;dbms_output.put_line(testID);dbms_output.put_line(testRevID);END;I get the following error, when i run the query in SQL Developer:Error report:ORA-01422: exact fetch returns more than requested number of rowsORA-06512: at line 1101422. 00000 - "exact fetch returns more than requested number of rows"*Cause: The number specified in exact fetch is less than the rows returned.*Action: Rewrite the query or change number of rows requestedCan anybody tell me what is wrong with the above query.. Any help appreciated.Thanks in advance.What I have tried:SELECT tlv.testrevid FROM TESTLIBREVISION tlvwhere tlv.revision = 2 and tlv.testid = 1604;dbms_output.put_line(testrevid);But when i run the above script i get single value. 解决方案 The problem is definitely only due to the select query returning more than one rows.plese check for other values. just try to find duplicate values 这篇关于运行脚本时Sql Developer查询错误的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
