Write the SQL code to complete each of the three (3) problems presented below: 1. Write the SQL query to show all invoices (LGINVOICE) with a total (INV_TOTAL) of at least $100. You should output all columns from the invoice table. 2. Write the SQL query to list all customers with invoices totaling (INV_TOTAL) more than $250. You should output the following columns (CUST_CODE, CUST_FNAME, CUST_LNAME, INV_TOTAL). Note that this query requires data from both the LGCUSTOMER and LGINVOICE tables. 3. Write the SQL query to list the line item details (including product and brand information) for the invoice with the highest total (INV_TOTAL). You should output the following columns (LINE_NUM, PROD_SKU, PROD_DESCRIPT, PROD_TYPE, BRAND_NAME, LINE_QTY, LINE_PRICE). Note that this query requires data from the LGINVOICE, LGLINE, LGPRODUCT, and LGBRAND tables
