我正在尝试使用double when语句但不确定如何执行此操作.这是我正在使用的代码
CASE WHEN dbo.CSEFExtWorkflowAbsences.Number41=1 THEN dbo.CSEFExtWorkflowAbsences.Text1
WHEN dbo.CSEFExtWorkflowAbsences.Number41=2 THEN dbo.CSEFExtWorkflowAbsences.Text2
WHEN dbo.CSEFExtWorkflowAbsences.Number41=3 THEN dbo.CSEFExtWorkflowAbsences.Text3
WHEN dbo.CSEFExtWorkflowAbsences.Number41=4 THEN dbo.CSEFExtWorkflowAbsences.Text4
WHEN dbo.CSEFExtWorkflowAbsences.Number41=5 THEN dbo.CSEFExtWorkflowAbsences.Text5
WHEN dbo.CSEFExtWorkflowAbsences.Number41=6 THEN dbo.CSEFExtWorkflowAbsences.Text6
WHEN dbo.CSEFExtWorkflowAbsences.Number41=7 THEN dbo.CSEFExtWorkflowAbsences.Text7
WHEN dbo.CSEFExtWorkflowAbsences.Number41=8 THEN dbo.CSEFExtWorkflowAbsences.Text8
WHEN dbo.CSEFExtWorkflowAbsences.Number41=9 THEN dbo.CSEFExtWorkflowAbsences.Text9
WHEN dbo.CSEFExtWorkflowAbsences.Number41=10 THEN dbo.CSEFExtWorkflowAbsences.Text10
WHEN dbo.CSEFExtWorkflowAbsences.Number41=11 THEN dbo.CSEFExtWorkflowAbsences.Text11

WHEN dbo.CSEFExtWorkflowAbsences.Number41=15 THEN dbo.CSEFExtWorkflowAbsences.Text15
WHEN dbo.CSEFExtWorkflowAbsences.Number41=16 THEN dbo.CSEFExtWorkflowAbsences.Text16
WHEN dbo.CSEFExtWorkflowAbsences.Number41=17 THEN dbo.CSEFExtWorkflowAbsences.Text17
