Always remember to index columns used in WHERE and JOIN clauses in SQL for faster and more efficient performance. #ProgrammingTips #SQLCoding
Writing efficient SQL queries is essential for optimizing code. Be sure to use the EXPLAIN ANALYZE command to get useful performance feedback. #SQLCoding #Programming
"Organize your SQL for readability & maintainability: break down into separate files for DDL, DML, and DCL (Data Definition, Manipulation & Control Statements) #SQLCoding #DatabaseProgramming"
#SQLCoding-ton_Day_1 SELECT * FROM table_name This selects all records (rows and columns) from a table in a database
Run a #SQL EXPLAIN statement first to help you identify where a query can be optimized. #ProgrammingTIP #SQLCoding
#SQLCoding-ton_Day_3 *SELECT DISTINCT city FROM employeeTbl* The SELECT DISTINCT statement is used to return only distinct (different) values
#SQLCoding-ton_Day_2 *SELECT fname, lname, gender FROM table_name* This selects all rows based on the fname, lname and gender columns from a table in a database
#SQL Tip - Use the EXISTS and NOT EXISTS statements to find data that does or does not exist in other tables. #SQLCoding #Programming
#SQLCoding-ton_Day_9 SELECT fname, lname, contact FROM employeeTbl ORDER BY city DESC In the example the DESC keyword is used to order records from Z-A based on the city column
#SQLCoding-ton_Day_7 *SELECT * FROM employeeTbl WHERE city = “Accra” AND city = “Kumasi” In this example WHERE clause is combined with the comparison operator (=) and the logical operator (AND) to select employees in the city Accra and Kumasi

#SQLCoding-ton_Day_12 SELECT COUNT(empID) FROM employee Aggregate function is used to perform calculations on set of values and return a single value (sum, count, max, min, avg) *COUNT() functions used above finds the count of employees*
