The names of the columns must be separated by a comma. To learn more about data science please visit- Learnbay.co
Well, depens on which schema you want to check . I assume that you want to find a table name from any schema. So, you can query the "dba_tab_cols" view. SELECT table_name, owner FROM dba_tab_cols WHERE column_name="your_column";

Correlated query has a subquery in it which accesses the column name of a table alias which is outside the subquery.
In the context of databases, a query refers to a request for retrieving, updating, or manipulating data stored within a database. It is a way to communicate with the database to perform operations such as data retrieval, insertion, updating, and deletion based on specific criteria. Queries are typically written using query languages like SQL (Structured Query Language) to interact with databases.
Column names do not have to be unique within a database; they only have to be unique within a particular table. If a query joins two table where each contains a field with the same name and that field is specified in the SELECT or WHERE clause, not qualifying the column name with the table name results in ambiguity as to which field is desired.
