SQL: Create a SQL query that uses a correlated subquery to display the descriptions for products provided by a vendor in area code 904. The outer query will use the PRODUCT table, then use WHERE EXISTS, then the subquery which will use the VENDOR and PRODUCT tables via a join (a join should be used here). [hint: you should have 3 records of output]. My code: select p_descript from product where exist(select v_areacode from vendor where v_areacode = '904') ; I am getting an error but I can't see what is missing. ORA-00936: missing expression
SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.
