我有一个包含以下表格的查询：tblPosition, tblWorkArea, tblSkills。
tblPosition：ID_Position, Position tblWorkArea：ID_WorkArea, WorkArea, Position tblSkills：ID_WorkArea，以及大约40种不同数字值的不同技能。我想设置一个select查询，以便在给定以下参数的情况下生成表：WorkArea和Position。例如，工作区域是工程，位置是技术人员。生成的表应仅列出适用于这两个参数的那些技能（40个中）。 ID_WorkArea适用于WorkArea和Position的每个组合。所有ID_WorkArea都存储在tblSkills中以及所有技能。我想制作一个选择查询来选择给定ID_WorkArea的某些技能。
技能范围从0到30个数值。任何值为0的技能都意味着它不是必需的。
我对select查询的当前设置如下：
ID_WorkArea，WorkArea，Position，Skill1，skill2等.WorkArea和Position的标准是[Enter WorkArea]和[Enter Position]。每项技能的标准是＆lt; 0＆gt;。
问题是当我运行它时，至少有一个技能值为0的ID根本不返回数据记录。我希望看到剩下的技能，减去值为0的技能领域。
是否可以运行单个查询，根据输入的参数生成不同数量的字段？
