The Query Wizard in database management systems, like Microsoft Access, is a tool that simplifies the process of creating queries to retrieve data from tables. Users can select the desired table, choose specific fields, and set criteria to filter results without writing SQL code. The wizard guides users through a step-by-step process, allowing them to customize their queries easily and save time when extracting information. This makes it accessible for users with varying levels of technical expertise.
Query is a thing you are searching for in the database.
Unless you want to drop (delete) the entire database, you will must delete tables individually. To delete tables individually, execute the query "SHOW TABLES" in your database which will return a list of all table names. Iterate through that resultset and execute "DROP TABLE {$table_name}"

Join query are basically of three types : 1) Cross Join -- That is use to retrieve data from two tables on a condition (optional), there we get m*n no. of records(m is no of rec in first table and n is the no. of records in another table) 2) Inner Join : we use this join to retrieve values from two tables that satisfies given matching condition : as :: select Product_Category from Product_Detail INNER JOIN Product_Scenerio ON Product_Detail.Product_Id = Product_Detail.Product_Id. Product_Scenerio . 3) Outer Join : this is used in three way: a) Left Outer Join -- it is used to retrieve records from both tables that satisfies given condition including all records from left(First) table whether it do not satisfy condition ...try it practically ** related columns in right table has NULL values in records b) Right Outer Join :: It is used when we want to fetch all records from right(second) table whether that do not match with condition specified with JOIN . ** related columns in right table has NULL values in records c) Full Outer Join :: It is combination of Inner join + left Outer join + right Outer join .Here we get all records from both tables that do not match condition .

Query Wizard is a tool commonly found in database management systems and software applications that simplifies the process of creating database queries. It provides a user-friendly interface that guides users through selecting tables, fields, and criteria to generate SQL queries without requiring extensive programming knowledge. This feature is particularly useful for users who need to extract or manipulate data quickly and efficiently. Overall, Query Wizard enhances accessibility and productivity in data analysis tasks.
You would use a JOIN query for this.
