私のデータベースでは、「children」、「personal」、「spouse」、「occup_contact」、「res_contact」という名前の5つのテーブルと列名があります
children(pid,pnochild,pcname,pcblood,pcdob)
occup_contact(pid,poccup_nature,poccup_type,poccup_add,pemail,poccup_phone,poccup_mobile)
personal(pid,pname,pfname,pmname,pfhname,pdob,pgender,pedulvl,pedu,pblood,gotra,panth,pmarritalstatus)
res_contact (pid,pres_add,pres_phone,pres_mobile)
spouse (pid,psname,psedulvl,psedu,psblood,psdob)
次に、私のフォームで、これらすべてのテーブルの結果を次のような変更された列名で結合したいという点で、データグリッドビューをドラッグしました
name not 'pname' it should be Name
fathername not 'pfname' it should be Father's Name........so on
個人の名前に基づいてすべてのテーブルの結合結果を取得するには、どの select ステートメントを使用する必要がありますか。つまり、個人テーブルの pid 列が主キーであり、他のすべてのテーブルで外部キーとして使用される個人テーブルの pname 列です。すべてのテーブルは個人用テーブルに依存しています
私はこれを使用しました
