访问 table 中的表达式
Access expressions in table
我会在 table 中收集我的 IIF 或 switch 表达式作为记录(超过 40 个):
tbl_filter:
过滤器
Description LIKE '*SCREW*',"Screw"
Description LIKE '*SOCKET*',"SScrew"
如何在查询的切换函数中使用 tbl_filter 中的表达式集合?
类似这样:
SELECT Item, switch(Select * from tbl_Filter) AS Cathegory FROM tbl_Materials
提前感谢您的帮助
我想你的意思类似于下面的意思。
tbl_Filter
Contains Filter
Screw Screw
Socket Sscrew
tbl_Main
Description
Screws and sockets
Screw
Socket
查询SQL
SELECT tbl_Main.Description, tbl_Filter.Filter
FROM tbl_Main, tbl_Filter
WHERE tbl_Main.Description Like "*" & [Contains] & "*"
结果
Description Filter
Screws and sockets Screw
Screws and sockets Sscrew
Screw Screw
Socket Sscrew
