While I was switching a legacy site from servers… some SQLs weren’t working…
#1366 - Incorrect integer value: '' for column 'upd_iid' at row 1
This worked for me…
I’v edited my /etc/mysql/my.cnf and comment the original “sql_mode” and added this one
sql_mode = ""
Save and restart mysql!
On your mysql console…
mysql> SHOW VARIABLES LIKE "general_log%";
+------------------+----------------------------+
| Variable_name | Value |
+------------------+----------------------------+
| general_log | OFF |
| general_log_file | /var/run/mysqld/mysqld.log |
+------------------+----------------------------+
mysql> SET GLOBAL general_log = 'ON';Then!
tail -f -n200 /var/run/mysqld/mysqld.log
After debugging… don’t forget to turn it OFF!
mysql> SET GLOBAL general_log = 'OFF';
ERROR 1214 (HY000) at line 323: The used table type doesn’t support FULLTEXT indexes
Upgrade to 5.6 and use InnoDB Full-Text Search
This is how…
On mysql set your table(s)’s filed(s) to utf8mb4_general_ci.
$db['default']['char_set'] = 'utf8mb4';
$db['default']['dbcollat'] = 'utf8mb4_general_ci';https://stackoverflow.com/questions/16828197/displaying-utf8-character-on-codeigniter
PHP MySql compare table structure – ONLINE!
This site can compare two MySQL database table structures and generate the necessary SQL statements to update the second table to be identical to the first.
It compares the table creation SQL statements of two MySQL databases as outputted from the mysqldump command or phpmyadmin.
The site determines what changed from one database to the other and generates schema alteration SQL statements to create, drop and alter tables that should be applied to one database to make it have the same schema of the other.
So!, I was/am writing a subquery to get a value to rating_stars… and I got this (beginner) error…
mysql – #1241 – Operand should contain 1 column(s)
(SELECT value, (sum(value)/count(value)) FROM model_ratings WHERE modelId = id) AS rating_stars
Subquery should return one column, whatever corresponds to rating_stars.
(...) (SELECT (sum(value)/count(value)) FROM model_ratings WHERE modelId = id) AS rating_stars (...)
So!, I have with almost 3Gb… and I need to make a search & replace…
This looks the best way to me…
EXPORT FROM MYSQL > LINUX SEARCH & REPLACE > IMPORT TO MYSQL
Dump database to text file
mysqldump -u user -p databasename > ./db.sqlRun sed command to find/replace target string
sed -i 's!oldString!newString!g' ./db.sqlReload the database into MySQL
mysql -u user -p databasename < ./db.sqlAs copied from http://stackoverflow.com/questions/11839060/find-and-replace-text-in-the-entire-table-using-a-mysql-query
Let’s run
mysql_upgrade -u root -pto solve it!
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column ” which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Lets edit my.cnf
sudo nano /etc/mysql/my.cnf
and add the following lines to it, save and exit nano….
[mysqld]
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTIONLets restart mysql
sudo service mysql restart
It should work! 😉
Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column ‘johnny.category.categoryId’ which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
Let run the following command in mysql…
it worked for me on mysql Ver 14.14 Distrib 5.7.12, for Linux (x86_64)
set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
