摘　　要：针对Visual FoxPro教学中学生学习SQL查询命令的困难,采用形象化的指针工具,结合PPT课件动画演示和上机实际操作,使学生能够利用指针工具分析SQL查询命令的执行过程和最终结果,从而促进学生对SQL查询命令的理解.实践表明,通过指针工具能够提高学生分析问题、设计处理步骤、设计命令格式及相关参数、预测处理结果的能力,充分调动学生思维的积极性,提高教学效果.Because of the difficulties the students have when learning how to query orders in Structured Query Language (SQL)of the common basic course "Visual FoxPro Database and Application",we use iconic record pointers tool,combining PPT teaching contents and in -class experiments to help the students analyze the process and the final result to query orders in SQL so as to in-crease their understanding.The practice showed that the record pointer tool can increase the capability of students in analyzing problems,designing process,order format and relevant parameter and predicting results;increase the activity of thinking and teaching effect.
