If a significant data value skew exists for a column referenced in a query predicate, make sure that DB2 knows this, preferably by generating column-value histogram statistics using RUNSTATS.
如果查询谓词中引用的列存在显著的数据值倾斜,那么要确保DB 2了解这一情况,最好是使用RUNSTATS生成列值柱状图统计数据。
The behavior of the optimizer is influenced by three key factors: the value of OPTCOMPIND parameter in the Informix configuration file, query directives, and the accuracy of internal statistics.

Query results are returned pre-processed by the pureQuery runtime into a wide choice of objects, such as Iterators of populated pureQuery beans, or Lists of column name to column value Maps
返回查询结果,由pureQuery预处理为多种对象,例如已填充的 pureQuerybean的Iterators,或者列名的Lists,或者列值Maps。
From the new tables, the query inherits Lookup fields, which let you change field values by picking values from a list instead of having to correctly type a value.
从新表中,查询继承了“查阅”字段,这样您就可以从列表中挑选值来更改字段的值,而不必正确地键入值。
While the query or stored procedure you select may return more than a single value, the method created by the wizard will only return a single value.

Queries that we think of as returning no value actually do return a value - an integer containing the number of rows affected by the query.
