VBA (Visual Basic for Applications) is a programming language used in Microsoft Office applications, including Excel. SQL (Structured Query Language) is a programming language used to manage and manipulate data in relational databases.

In Excel, VBA can be used to connect to a database using SQL and perform various operations on the data. Here's an example of how to use VBA and SQL in Excel:

1. Open Excel and go to the Developer tab.
2. Click on Visual Basic to open the VBA editor.
3. In the editor, go to Tools > References and select Microsoft ActiveX Data Objects.
4. Insert a new module and enter the following code:

Sub SQLQuery()
    Dim conn As ADODB.Connection
    Dim rs As ADODB.Recordset
    Dim sql As String
    
    Set conn = New ADODB.Connection
    Set rs = New ADODB.Recordset
    
    'Connection string to your database
    conn.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=DatabaseName;Data Source=ServerName"
    
    'SQL query
    sql = "SELECT * FROM TableName"
    
    'Open the connection and execute the query
    conn.Open
    rs.Open sql, conn
    
    'Loop through the recordset and print the results to the sheet
    Do While Not rs.EOF
        Range("A1").Value = rs("Column1")
        Range("B1").Value = rs("Column2")
        rs.MoveNext
    Loop
    
    'Close the recordset and connection
    rs.Close
    conn.Close
    
End Sub

5. Replace "DatabaseName" and "ServerName" with your actual database and server names.
6. Replace "TableName" and "Column1" and "Column2" with your actual table and column names.
7. Run the code and it will connect to the database, execute the SQL query, and print the results to the sheet.

This is just a basic example, but VBA and SQL can be used to perform more complex operations, such as updating data, deleting data, and creating new tables.

Excel VBA SQL refers to the use of SQL (Structured Query Language) commands within VBA (Visual Basic for Applications) code in Excel. This allows users to interact with databases and perform operations such as querying, inserting, updating, and deleting data.

Some examples of using SQL in Excel VBA include:

1. Retrieving data from a database and displaying it in an Excel worksheet
2. Updating data in a database based on user input in an Excel form
3. Deleting data from a database based on specific criteria
4. Inserting new data into a database based on user input in an Excel form

To use SQL in Excel VBA, you need to establish a connection to a database using a connection string. Once the connection is established, you can execute SQL commands using the "Execute" method of the connection object. You can also use the "Recordset" object to retrieve data from a database and manipulate it in Excel.

Overall, Excel VBA SQL is a powerful tool that allows users to perform advanced database operations directly from within Excel.
