1.DB2数据库表操作错误SQL0668N Operation not allowed for reason code "1" on table "XXXX". SQLSTATE=57016的解决方法
The table is in Check Pending state. The integrity of the table is not enforced and the content of the table may be invalid.
An operation on a parent table or an underlying table that is not in a check pending state may also receive this error if a dependent table is in a check pending state.
Execute the SET INTEGRITY statement with the IMMEDIATE CHECKED option on table table-name to bring the table out of the Check Pending state.

For a user maintained materialized query table, execute the statement with the IMMEDIATE UNCHECKED option instead of the IMMEDIATE CHECKED option.:
ERROR [57016] [IBM][DB2/AIX64] SQL0668N Operation not allowed for reason code "1" on table "XXXX". SQLSTATE=57016
可能有一行或多行违反了对数据定义的约
束。此表不能用于操作。若从属表处于检查暂挂状态，则对不处于检查暂挂
状态的父表的操作也可能接收到此错误。
用户响应: 执行带有 IMMEDIATE CHECKED 选项的 SET INTEGRITY
语句，并确保数据符合对该表或从属于它的表定义的所有约束。
set integrity for 表名immediate checked
2.对表进行任何操作都不被允许，提示SQLSTATE=57016 SQLCODE=-668 ，原因码 "7"的错误：SQL0668N Operation not allowed for reason code "7" on table XXX. 解决方法为：
参考原文为：
Operation not allowed for reason code reason-code on table table-name.
Explanation: Access to table table-name is restricted. The cause is based on the following reason codes reason-code: 7
The table is in the reorg pending state. This can occur after an ALTER TABLE statement containing a REORG-recommended operation.7
Reorganize the table using the REORG TABLE command (note that INPLACE REORG TABLE is not allowed for a table that is in the reorg pending state).
其中：
reorg table <tablename> 通过重构行来消除“碎片”数据并压缩信息，对表进行重组。
runstats on table <tbschema>.<tbname> 收集表 <tbname> 的统计信息。
reorgchk on table all 确定是否需要对表进行重组，对于对所有表自动执行 runstats 很有用。
>>> reorg 和runstats 都是单个表优化，初始化的命令：
runstats on table administrator.test;
reorg table administrator.test;
执行命令：
- 执行 CALL SYSPROC.ADMIN_CMD('reorg table XXXXXXX')
- XXXXXXX'为表名
Operation not allowed for reason code reason-code on table table-name.

3.Operation not allowed for reason code "3" on table xxx
问题：
select count(*) from schema_name.table_name with ur;
: ERROR [57016] [IBM][DB2/LINUXX8664] SQL0668N Operation not allowed for reason code "3" on table "schema_name.table_name". SQLSTATE=57016
我刚才
Reorg table schema_name.table_name;
DB2 Database Error: ERROR [01H52] [IBM][DB2/LINUXX8664] SQL2216N SQL error "-668" occurred while reorganizing a database table or its indexes. SQLSTATE=01H52
1.重组表的时候不能进行任何操作
select count(*) from schema_name.table_name with ur;
: ERROR [57016] [IBM][DB2/LINUXX8664] SQL0668N Operation not allowed for reason code "3" on table "schema_name.table_name". SQLSTATE=57016
我刚才
Reorg table schema_name.table_name;
DB2 Database Error: ERROR [01H52] [IBM][DB2/LINUXX8664] SQL2216N SQL error "-668" occurred while reorganizing a database table or its indexes. SQLSTATE=01H52
1.重组表的时候不能进行任何操作
2.可以删除表重建
3.使用 load 命令，重启或者断开load pending状态，load..terminate,load..replace或load..restart解除暂挂状态
