Learn how to use the basic SQL commands in the most productive & efficient manner with our expert solutions. Score top grades & expand your ideas & knowledge about commands such as:

  • AND & OR- Two of the most common logical operators in computer science & programming. Find out incredible ways to create robust conditions and how to combine different operators to create powerful custom queries.
  • BETWEEN- The BETWEEN operator is somewhat akin to a comparison operator and helps you choose a value within a given range. You can use it to fetch any data – number, text, or even dates.
  • COMPARISON OPERATORS- =, <,>,>=, <=, <> are the most commonly used comparison operators used in SQL. They are generally used in tandem with logical operators, and the results are used to filter & extract data.
  • DATA TYPES- Struggling to work with different data types in SQL? Avail of our SQL homework help and learn how to define different data in databases tables, manipulate, fetch, & operate on them.
  • DELETE- Use this command to remove a table's entire record or row. Be careful while using it, as without a WHERE clause, executing the DELETE command will wipe out all records in a table.
  • DISTINCT- Returns only distinct or different values and no duplicates. A convenient command!
  • EXCEPT- This clause bridges two SELECT statements and returns only those rows in the first SELECT statement that are not selected by the second SELEC statement.
  • EXISTS- Checks whether a record exists in a subquery.
  • FROM- Used to choose the table from which data is queried.
  • GROUP BY- Group rows with the same values. The statement is generally used with SQL’s aggregate functions such as MAX(), MIN(), AVG(), etc.
  • HAVING- Used with aggregate functions in cases where the WHERE clause can’t be used. You will have to decide which to use.
  • IN- Specifies the values in a WHERE clause.
  • INSERT INTO- The statement adds new records in a table.
  • INTERSECT- Works just like the EXCEPT clause, with the critical difference being that INTERSECT returns data that satisfies both SELECT statements.
  • IS NOT NULL & IS NULL- NULL signifies a field with no value. These two statements are self-explanatory and check whether a field is empty.
  • JOIN- The JOIN clause is a powerful command that merges a row from two or more tables. There's generally a column that relates both.
  • LIKE- Use it along with a WHERE clause to fetch data that adhere to a specific pattern.
  • MINUS- Used along with two SELECT statements and fetches results that are unique to only the first SELECT statement & not common to both queries.
  • NOT- Negates a condition in a query.
  • ORDER BY- The ORDER BY statement sorts query results in either the ascending or descending order.
  • SELECT- The ultimate DQL command, the SELECT statement chooses the location in a database from where to extract data or perform operations upon.
  • SELECT LIMIT & TOP- SELECTS TOP returns data from the top of a table, while SELECT LIMIT limits the number of records fetched from single or multiple tables based on a specific limit.
  • TRUNCATE- A data definition language; the TRUNCATE command removes all entries in a table, emptying it for reuse.
  • UNION & UNION ALL- UNION Merges the results of two or more SELECT statements but keeps unique records. UNION ALL merges everything, including duplicates.
  • UPDATE- As the name suggests, it updates all current records in a table.
  • WHERE- Used in tandem with a condition to filter data from a table.

The above is just a small list of essential SQL commands. Our experts can solve problems of any difficulty level using any basic SQL command, so you've got nothing to worry about. And that's not all! AH.us' database homework helpers can also craft impeccable programs in advanced SQL.

Here are some of the most commonly used advanced SQL commands. Please find out how they are used in queries effectively:

  • ALTER TABLE- Use this command if you need to change the internal structure of a schema, that is, add, delete, or modify columns in an existing table.
  • COMMENTS- Single line and multi-line comments are used to explain certain sections or prevent execution of the execution of a command in an SQL program.
  • CREATE TABLE- A data-definition language command is self-explanatory and creates new tables in a database.
  • CREATE TABLE AS- Uses an existing or selected table’s content to create a new table.
  • DROP TABLE- It removes an existing table from a database.
  • GLOBAL TEMP- Global temporary tables are generated using the CREATE TABLE clause and are accessible to all sessions, connections, or users.
  • INDEX- They offer a handy way to retrieve data from tables using keys derived from one or more tables in a specific database.
  • LITERALS- Literals are constant values. SQL defines four major literals types: character & bit strings, and exact & approximate numeric.
  • LOCAL TEMP- Local temporary tables are also created using the CREATE TABLE command but are visible only to the user who creator or connection that built it.
  • PRIMARY KEY- Primary keys are unique identifiers of every single record in a table.
