SET @sql = CONCAT(' SELECT      *,
                            customerID,
                            customerCode `Customer Code`,
                            CONCAT(firstName, ' ', surname) AS `Name`,
                            street `Street`,
                            phone `Phone` 
                    FROM tblCustomers  
                    WHERE customerCode like ''', @custCode ,'%''');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

或参数化，

SET @sql = '    SELECT      *,
                        customerID,
                        customerCode `Customer Code`,
                        CONCAT(firstName, ' ', surname) AS `Name`,
                        street `Street`,
                        phone `Phone` 
                FROM tblCustomers  
                WHERE customerCode LIKE CONCAT(?, ''%'')';

PREPARE stmt FROM @sql;
EXECUTE stmt USING @custCode;
DEALLOCATE PREPARE stmt;

在Store Procedure，MS SQL中使用execute（'select * from tablename'）有什么用处
