摘要： Approaches, techniques, and mechanisms are disclosed for maintaining a set of baseline query plans for a database command. Except in rare circumstances, a database server may only execute a command according to a baseline plan, even if the database server predicts that a different plan has a lower cost. The set of baseline plans are plans that, for one reason or another, have been determined to provide acceptable actual performance in at least one execution context. When the database server receives a request to execute a particular command, the database server, if possible, always executes the command according to the lowest predicted cost baseline plan. The database server may evolve the plan baseline to include additional plans by generating and testing new plans in response to new requests to execute the database command, or as part of a query optimization or tuning process.

摘要： A method and apparatus for approximating a database statistic, such as the number of distinct values (NDV) is provided. To approximate the NDV for a portion of a table, a synopsis of distinct values is constructed. Each value in the portion is mapped to a domain of values. The mapping function is implemented with a uniform hash function, in one embodiment. If the resultant domain value does not exist in the synopsis, the domain value is added to the synopsis. If the synopsis reaches its capacity, a portion of the domain values are discarded from the synopsis. The statistic is approximated based on the number (N) of domain values in the synopsis and the portion of the domain that is represented in the synopsis relative to the size of the domain.

摘要： Under a type of query transformation referred to herein as join factorization, the branches of an UNION/UNION ALL query that join a common table are combined to reduce accesses to the common table. The transformation can be expressed as (T1 join T2) union all (T1 join T3)=T1 join (T2 union all T3), where T1, T2 and T3 are three tables. A given query may be rewritten in many alternate ways using join factorization. Evaluating each alternative can be expensive. Therefore, the alternatives are generated and evaluated in a way that minimizes the cost of evaluating the alternatives.

摘要： A gravity sensor has a photo interrupter and a gravity wheel. The photo interrupter has a housing, a cavity in the housing, a light emitter on one side of the housing and a light detector on the other side of the housing. The gravity wheel points in a direction of gravity and has a pivot at center thereof and pivotally arranged on the housing, a plumb at one edge of the gravity wheel and a plurality of through holes annularly arranged in the gravity wheel. The gravity wheel has a portion present in the cavity. An inclined angle of a test object is determined by calculating relative movement between the photo interrupter and the gravity wheel.

摘要： The present invention involves the creation of defined chromosomal deficiencies, inversions and duplications using Cre recombinase in ES cells transmitted into the mouse germ line. These chromosomal reconstructions can extend up to 3-4 cM. Chromosomal rearrangements are the major cause of inherited human disease and fetal loss. Additionally, translocations and deletions are recognized as major genetic changes that are causally involved in neoplasia. Chromosomal variants such as deletions and inversions are exploited commonly as genetic tools in organisms such as Drosophila. Mice with defined regions of segmental haploidy are useful for genetic screening and allow accurate models of human chromosomal diseases to be generated.
