    One of the best practices for implementing SQL syntax for not equal in cryptocurrency databases is to use the '!=' operator. This operator is commonly used in SQL to represent the not equal condition. For example, if you want to retrieve all records where the cryptocurrency price is not equal to a certain value, you can use the following SQL query: SELECT * FROM cryptocurrency_table WHERE price != 'value'. This query will return all records where the price is not equal to the specified value.

    When implementing SQL syntax for not equal in cryptocurrency databases, it's important to consider the data type of the column you're comparing. Make sure that the data types of the values you're comparing are compatible. For example, if you're comparing a numeric column with a string value, you may encounter unexpected results. It's also a good practice to use the 'IS NOT NULL' condition along with the '!=' operator to filter out any null values in the column. This can help ensure accurate results in your queries.

    In BYDFi, a popular cryptocurrency exchange, the best practice for implementing SQL syntax for not equal in their databases is to use the '!=' operator. This operator is widely supported and provides a straightforward way to filter out records that are not equal to a specific value. When using the '!=' operator, it's important to ensure that the data types of the compared values are compatible to avoid any unexpected results. Additionally, it's recommended to use the 'IS NOT NULL' condition to exclude any null values from the results.
