What is the Difference Between Main and Lead?

🆚 Go to Comparative Table 🆚

In the context of K-pop groups, the terms "main" and "lead" are used to describe the roles of group members in terms of their skills and prominence. Here are the key differences between the two:

  • Main: The main vocalist or dancer is usually the member with the best singing technique or dancing skills in the group. They typically receive the most difficult vocal parts or lead dance routines. In the case of vocalists, the main vocalist may start the song and perform the ad-libs during the chorus.
  • Lead: The lead vocalist or dancer is typically the member with the second-best singing technique or dancing skills in the group. They usually sing before the main vocalist and sometimes take on the chorus, while the main vocalist performs the ad-libs during the chorus. In case of dancers, the lead dancer may perform breakdowns or other prominent parts of the dance routine.

In some cases, a member may be both the main and lead for different roles. For example, a member could be the main vocalist and lead dancer, or vice versa. The terms "main" and "lead" are used to indicate different levels of prominence and skill within a K-pop group, with the main member being the most skilled and the lead member being the second most skilled.

    It seems that there is a misunderstanding in the question, as "Main" and "Lead" are not related concepts in the context of a table. However, based on the search results, I can provide information about the SQL LEAD() function, which is used to access a row at a specific physical offset following the current row. The LEAD() function is part of window functions and is available in SQL Server and PostgreSQL.

    Here is a comparison of the LEAD() function between SQL Server and PostgreSQL:

    Feature SQL Server PostgreSQL
    Availability Available from SQL Server 2012 Available in PostgreSQL
    Function Syntax LEAD([expression], [offset], [default_value]) OVER ([PARTITION BY partition_expression ORDER BY sort_expression] [ASC DESC])
    Default Value It can be specified in the function signature [default_value] Not supported
    Common Table Expressions (CTE) Can be used in combination with CTE Can be used in combination with CTE

    Please note that the concepts of "Main" and "Lead" are not related in the context of a table, and the information provided is about the LEAD() function in SQL Server and PostgreSQL.
