Excel 公式幫助獲得正確的語法

Question

Excel 版本：2016

我在這里問了主要問題，這是該問題的擴展。

在 EXCEL 內構建 SQL SELECT 語句

只要 sql“AND”子句中有值，我就需要擴展所有列的邏輯。

例如。 AND TAB1.COLUMNA = TAB2.TCOLUMNA AND TAB1.COLUMNB = TAB2.COLUMNB依此類推，僅當 DIM 列中有值時。

我不確定如何使用 SUBSTITUTE 和 TRIM 函數動態嵌入它。

編輯：公式

="select * from (SELECT RET_ID,RET_NM,"&SUBSTITUTE(TRIM(C2&" "&D2&" "&E2&" "&F2)," ",",")&" FROM 
TABLEX ORDER BY "&SUBSTITUTE(TRIM(C2&" "&D2&" "&E2&" "&F2)," ",",")&") TAB1 FULL OUTER JOIN   (SELECT RET_ID,RET_NM,"&SUBSTITUTE(TRIM(C2&" "&D2&" "&E2&" "&F2)," ",",")&" FROM 
TABLEX ORDER BY "&SUBSTITUTE(TRIM(C2&" "&D2&" "&E2&" "&F2)," ",",")&") TAB2 ON TAB1.RET_ID = TAB2.RET_ID AND TAB1.RET_NM = TAB2.RET_NM  "

Answer 1

解決了，通過這段代碼

"&IF(LEN(D2)>0,CONCATENATE("AND COALESCE(TAB1.",D2,",'')","="," COALESCE(TAB2.",D2,",'')"),"")&"
