title: Comparing one table in 2 schemas to find missing columns
body: <p>I made my researches; I didn’t find something similar to my question. If my question is duplicated please excuse me because I didn’t find in my researches.</p>
  
  <p>I have 2 schemas, schema1 and schema2, and both of them have the same 6 tables.</p>
  
  <p>But not every table have the same column in the schema.</p>
  
  <p>Exp: tab1 has 40 column exists in schema1 but tab1 has 38 columns exists in schema 2. So there are 2 missing columns I want to add them. There are data I need to insert.</p>
  
  <p>I can insert them manually but it will take me time, isn’t there a simple query?</p>
  
  <p>In my researched I found tools that help for that. Thanks</p>
