SQL EXEC Command Guide

The SQL EXEC command is used to execute stored procedures or execute dynamic SQL statements. This is how it is used:

1. Execute a stored procedure:
   EXEC stored procedure name [parameter1, parameter2, …];
2. For example:
   Execute the stored procedure sp_GetCustomerInfo with the parameter CustomerID equal to 1.
3. Note: Parameters can be input parameters, output parameters, or input/output parameters.
4. Execute dynamic SQL statement:
   EXECUTE(@dynamic SQL statement);
5. For example:

   Declare a variable named @SQL of type VARCHAR(100).
   Set @SQL equal to ‘SELECT * FROM Customers WHERE Country = ”USA”’.
   Execute the SQL statement stored in @SQL.

6. Note: Dynamic SQL statements need to be represented using string variables and executed using the EXEC command.

Make sure to have the necessary permissions and specify the correct parameters when using the EXEC command to execute a stored procedure or dynamic SQL statement.
