Question

我使用的函数用于覆盖包含以逗号分隔的名称的列“利益相关者”的字段。目标是将名称与存储在表“扬声器”中的名称进行比较，它由两列组成：“id_équipe”（包含团队名称auquelle属于介入者名称）和“nom_intervenant”（包含名称列表）。。那么，目标是将名称与存储在表格中的名称“干预”进行比较。如果结果是肯定的，我们采取代码中列出的步骤。

这是我使用的SQL查询：

update incident set groupes_intervenants=DETERMINE12(intervenants) WHERE Status like 'Closed'

结果将存储在“利益相关者群体”栏中。提前谢谢你。
