# Showing Sql Mode

__*SQL_MODE*__

+ Shows the current SQL mode:
  + `SELECT @@global.sql_mode;` 
  + `SELECT @@session.sql_mode;` 
  + `SELECT @@sql_mode;` 
+ Default SQL mode:
```
tidb> SELECT CONACT('\n',REPLACE(@@session.sql_mode,',','\n'))\G
*************************** 1. row ***************************
CONCAT('\n',REPLACE(@@session.sql_mode,',','\n')): 
~!@ONLY_FULL_GROUP_BY@!~
~!@STRICT_TRANS_TABLES@!~
~!@NO_ZERO_IN_DATE@!~
~!@NO_ZERO_DATE@!~
~!@ERROR_FOR_DIVISION_BY_ZERO@!~
~!@NO_AUTO_CREATE_USER@!~
~!@NO_ENGINE_SUBSTITUTION@!~
1 row in set (0.00 sec)
```

------------------------------------------------------------
The presence of STRICT_TRANS_TABLES means that TiDB is in strict mode by default.

We will talk about strict mode later.
