Error Code: 1055 incompatible with sql_mode=only_full_group_by

Question

I have been having issues switching to an offline version of the Lahman SQL baseball database. I was using a terminal embed into an EDX course. This command runs fine on the

Answer 1

The accepted solution above didn't work for me on version 5.7.9, for osx10.9 (x86_64).

Then the following worked -

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';

Answer 2

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

** your query **

This will resolve your problem.

Answer 3

If you do as the picked answer, the @sql_mode may be like this—

',STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'.

there's a comma in front of the 'STRICT_TRANS_TABLES' string.

Just execute this—

set @@sql_mode = 
'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

it works.

Also, you can try following exp,

SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY,','');

I didn't test it, but I guess it may works.

Answer 4

For other use cases: You don't necessarily have to disable ONLY_FULL_GROUP_BY Given a case like this, According to mysql docs, "This query is invalid if name is not a primary key of t or a unique NOT NULL column. In this case, no functional dependency can be inferred and an error occurs:"

SELECT name, address, MAX(age) FROM t GROUP BY name;
ERROR 1055 (42000): Expression #2 of SELECT list is not in GROUP
BY clause and contains nonaggregated column 'mydb.t.address' which
is not functionally dependent on columns in GROUP BY clause; this
is incompatible with sql_mode=only_full_group_by

Instead you can use this ANY_VALUE('my_column_name') my_column_name Quoting the mysql docs, "In this case, MySQL ignores the nondeterminism of address values within each name group and accepts the query." Use ANY_VALUE() to refer to address:

SELECT name, ANY_VALUE(address), MAX(age) FROM t GROUP BY name;

Answer 5

In 5.7 the sqlmode is set by default to:

 ONLY_FULL_GROUP_BY,NO_AUTO_CREATE_USER,STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION

To remove the clause ONLY_FULL_GROUP_BY you can do this:

SET sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

This supposed you need to make that GROUP BY with non aggregated columns.

Answer 6

You can set the variables in mysql:

mysql> 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';
mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

Remember NO_AUTO_CREATE_USER will not work with mysql 8.

If that doesn't work just do:

mysql > set sql_mode = ''
