- MySQL database, with table Table 1 fields: NO_CRT, PRODUCT, PIECES PRICE_PCS. TOTAL PRICE (ION user, no password). There can be a maximum of two products with the same name (PRODUCT) and the same PRICE_PCS. The NO_CRT field has a unique value for each item. Reading from the keyboard a PRODUCT, respectively PRICE_PCS (using an HTML file to be written), by pressing a button the following operations will be performed (in a PHP script file): - search in the table of how many products with the same name PRODUCT and PRICE_PCS exist; - if no item is found, this will be signaled by a message (and exits the program); - if only one item is found, this item will be displayed in a table; - if two are found: - the second found item is deleted, and the data following it (more precisely PIECES) are transferred (added) to the remaining items (normally, also in the PIECES field); NO_CRT,is redone for the following deleted items (to have a successive numbering); - recalculate TOTAL…Given the follwing business rules, create an ERD. The ERD must include all primary keys, foreign keys, attributes, cardinalities. Also consider relational strengths (dashed lines or solid lines) : A university is divided into many schools. Each school has many departments, where each department belongs to one and only one school. Each department should have one or more professors assigned to it, where each professor cannot teach more than two courses. The university wants to record the following data for all professors: professor number and full name.SQL: Display all product information for products that contain the string ‘saw’ anywhere in their description. Remember to use the * for all attributes here and the LIKE keyword. [hint: you should have 5 rows of output] I understand how to create the query but I can't get the expected result. What am I doing wrong? My code: select * from product where p_descript like 'saw' ; I get no data found when I know there is supposed to be 5 rows of output.
