ORACLE 数据库select语句出现ORA-00905: missing keyword

select n.*,e.CFD SJCFD,CASE m.selectnameWHEN '往返' THEN n.chefei=n.OneWay + n.BackPayELSE n.chefei=n.OneWay END(AS n.carpay)->这个东西怪怪的，不可以这样吧！你去掉试试看可以运行不FROM FORMTABLE_MAIN_232_DT3 nleft outer join UF_BAOXIAO eon n.CFD=e.idleft outer join WORKFLOW_SELECTITEM mon n.DFC=m.selectvalue and m.fieldid=6050

上面是SQL语句,然后SQL语句报ORA

se?ora音标：[s?e'?o?a]词义：女士例句：1.Mire,le presento a la se?ora Lucía López.我向您介绍一下露西亚洛佩兹女士2.-Taxi para Maicon !' La se?ora llamó violentamente.去Maicon，那位女士大声叫着。

3.Esta se?ora es la reina de Inglaterra.这位女士是英国女王。

4.Aquí tiene su champán con fresas, se?ora.这是您的香槟和草莓，夫人...

我有一个库中的表,为什么select 一个字段就报ORA-00904错误

ORA-1578 is reported when a block is thought to be corrupt on read. Block 数据块 OERR: ORA-1578 “ORACLE data block corrupted (file # %s, block # %s)” Master Note OERR: ORA-1578 “ORACLE data block corrupted (file # %s, block # %s)” Fractured Block explanation Handling Oracle Block Corruptions in Oracle7/8/8i/9i/10g/11g Diagnosing and Resolving 1578 reported on a Local Index of a Partitioned table ORA-1410 ORA-1410错误常见于从INDEX或其他途径获得的ROWID，到数据表中查询发现没有对应的记录。

该错误可能因为数据表与其索引存在不一致，也可能是分区的数据表本身存在问题。

This error is raised when an operation refers to a ROWID in a table for which there is no such row.The reference to a ROWID may be implicit from a WHERE CURRENT OF clause or directly from a WHERE ROWID=… clause.ORA 1410 indicates the ROWID is for a BLOCK that is not part of this table. Row 数据行 Understanding The ORA-1410 Summary Of Bugs Containing ORA 1410 OERR: ORA 1410 “invalid ROWID” ORA-8103 该ORA-8103可能由多个BUG引起，例如LOB在10.2.0.4之前可能会由于BUG覆盖了另一张表的segment header，导致出现ORA-8103错误。

诊断该问题可以从数据表的segment header和data_object_id入手。

The object has been deleted by another user since the operation began.If the error is reproducible, following may be the reasons:- a.) The header block has an invalid block type.b.) The data_object_id (seg/obj) stored in the block is different than the data_object_id stored in the segment header. See dba_objects.data_object_id and compare it to the decimal value stored in the block (field seg/obj). Block 数据块 ORA-8103 Troubleshooting, Diagnostic and Solution OERR: ORA-8103 “object no longer exists” / Troubleshooting, Diagnostic and Solution ORA-8102 ORA-8102常见于索引键值与表上存的值不一致。

An ORA-08102 indicates that there is a mismatch between the key(s) stored in the index and the values stored in the table. What typically happens is the index is built and at some future time, some type of corruption occurs, either in the table or index, to cause the mismatch. Index 索引 OERR ORA-8102 “index key not found, obj# %s, file %s, block %s (%s) ORA-1499 对表和索引做交叉验证时发现问题 An error occurred when validating an index or a table using the ANALYZE command.One or more entries does not point to the appropriate cross-reference. Index 索引 ORA-1499. Table/Index row count mismatch OERR: ORA-1499 table/Index Cross Reference Failure – see trace file ORA-1498 Generally this is a result of an ANALYZE … VALIDATE … command.This error generally manifests itself when there is inconsistency in the data/Index block. Some of the block check errors that may be found:- a.) Row locked by a non-existent transaction b.) The amount of space used is not equal to block size c.) Transaction header lock count mismatch.While support are processing the tracefile it may be worth the re-running the ANALYZE after restarting the database to help show if the corruption is consistent or if it 'moves'.Send the tracefile to support for analysis.If the ANALYZE was against an index you should check the whole object. Eg: Find the tablename and execute:ANALYZE TABLE xxx VALIDATE STRUCTURE CASCADE; Block OERR: ORA 1498 “block check failure – see trace file” ORA-26040 由于采用过nologging/unrecoverable选项的redo生成机制，且做过对应的recover，导致数据块中被填满了0XFF，导致报错ORA-26040。

Trying to access data in block that was loaded without redo generation using the NOLOGGING/UNRECOVERABLE option.This Error raises always together with ORA-1578 Block 数据块 OERR ORA-26040 Data block was loaded using the NOLOGGING option ORA-1578 / ORA-26040 Corrupt blocks by NOLOGGING – Error explanation and solution ORA-1578 ORA-26040 in a LOB segment – Script to solve the errors ORA-1578 ORA-26040 in 11g for DIRECT PATH with NOARCHIVELOG even if LOGGING is ...
