Final answer:
The outer join condition in the given SQL query is col1=col2 or col1=col3. It combines records from two tables based on these conditions. Option 1,2 are correct.
Step-by-step explanation:
The outer join condition in the given SQL query is col1=col2 or col1=col3. An outer join is used to combine records from two tables even if there is no match between the columns being joined. It includes all the rows from both tables, and if there is no match, it assigns NULL values for the unmatched columns.
In this case, the condition col1=col2 or col1=col3 indicates that we want to retrieve all the records from both tables where either the values in col1 and col2 match, or the values in col1 and col3 match.
For example, if we have one table with col1 and col2 as the columns, and another table with col1 and col3 as the columns, this condition will retrieve all the rows where col1 matches with either col2 or col3.
The question concerns identifying the outer join condition in a given SQL query. An outer join condition in SQL is used to specify how rows from two tables should be combined when they do not have matching values in the columns being joined on.
To provide an exact answer, the actual SQL query is needed. However, based on the given options, an outer join condition typically looks like a comparison between columns, such as col1=col2, col1=col3, or col2=col3. It can also be a combination of conditions like col1=col2 AND col1=col3. The correct outer join condition can only be identified with the full context of the SQL query provided.
Without the specific query, it's not possible to definitively state which of the options 1) col1=col2, 2) col1=col3, 3) col2=col3, or 4) col1=col2 AND col1=col3 is the outer join condition.
