Question

I am trying to run a mysql script on centos. I have following mysql installed.
mysql> SHOW VARIABLES LIKE "%version%";
+-------------------------+------------------------------------------------------+
| Variable_name | Value |
+-------------------------+------------------------------------------------------+
| innodb_version | 5.6.25-73.1 |
| protocol_version | 10 |
| slave_type_conversions | |
| version | 5.6.25-73.1 |
| version_comment | Percona Server (GPL) |
| version_compile_machine | x86_64 |
| version_compile_os | Linux |
+-------------------------+------------------------------------------------------+
My sample script looks like:
DELIMITER //
DROP TRIGGER IF EXISTS trg_table1_category_insert;
DROP TRIGGER IF EXISTS trg_table1_category_update;
CREATE TRIGGER trg_table1_category_insert
AFTER INSERT
ON
table1_category
FOR EACH ROW
BEGIN
insert into table1_category_history (
table1_category_history_id,
table1_id,
transaction_start_date
) values (
new.table1_category_id,
new.table1_id,
new.create_date
);
END;
//
CREATE TRIGGER trg_table1_category_update AFTER UPDATE on table1_category FOR EACH ROW
BEGIN
insert into table1_category_history (
table1_category_history_id,
table1_id,
transaction_start_date
) values (
new.table1_category_id,
new.table1_id,
new.create_date
);
END;
//
DELIMITER ;
My database utilizes utf8 encoding. While importing this file in database on mysql client it keeps throwing
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '//
CREATE TRIGGER trg_table1_category_update AFTER UPDATE on ta' at line 1
I do not see any syntax error while using the delimiter, also it works on some machines absolutely fine, i have googled almost 100s of links and tried all the ways with downgrading/upgrading mysql server/client , my.cnf, charset etc it is not helping me out. Can anyone please help me on this? Can there be any settings done at client level to interpret it correctly.I am using the same version client that comes with mysql server installation.
