Hi, Table 1:(old File)
name number salray Test1 1 10000 Test2 2 10000 Table 2: (Delta File) name number salray Test1 1 40000 Test3 3 20000 i do not have date stamp field in this table. Having composite key of name and number fields. Expected Result name number salray Test1 1 40000 Test2 2 10000 Test3 3 20000 Current approach: 1) Delete row in table1 where table1.composite key = table2.composite key. 2) Union all table and table2 to get updated result. is this right approach?. is there any other way to achieve it? -- Selvam Raman "லஞ்சம் தவிர்த்து நெஞ்சம் நிமிர்த்து"
