LC_ALL=C fgrep -A 5 -B 5 'db_pd.Clients' eightygigsfile.sql

-A 5 -B 5 mean get 5 lines in for example
CREATE TABLE `r1_category` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `cat_name` varchar(100) NOT NULL,
  `caption` varchar(100) NOT NULL,
  `cat_caption` varchar(100) NOT NULL,
  `coupon_catid` int(11) DEFAULT NULL,
// Trimmed line
  KEY `cat_name` (`cat_name`,`discount_status`)
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=latin1;
/*!40101 SET character_set_client = @saved_cs_client */;

=> If you want full columns in CREATE query, increase A B parameter:
LC_ALL=C fgrep -A 15 -B 15 'db_pd.Clients' eightygigsfile.sql > Client.sql
    // grep  -Fn --text "1-Piston Calipers; Oversized" product_NOV_22.csv
    // -F for treat input pattern search as fixed string
