SQL Statement:

ADD COLUMN `datetime` TIMESTAMP(3) NOT NULL DEFAULT TIMESTAMP(3) AFTER `Result`
ERROR 1064: 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 '(3) AFTER Result' at line 2
i am new to mysql any help.Please
timestamp doesn't need length, also you are defining a default value but provided a datetype instead !!
here is what I mean
ALTER TABLE `Trade`.`details`
ADD COLUMN `datetime` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP AFTER `Result`

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 'TIMESTAMP DEFAULT now()' at line 1
Use CURRENT_TIMESTAMP
ALTER TABLE t_granja
ALTER COLUMN purchase_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP;
I want to change my field name to default Null but i am unable to solve this issue Here i am trying to change my deleteAt field to defaut Null but its giving me the error

Here is my code
DB::statement('ALTER TABLE insurance CHANGE COLUMN deleted_at deletedAt timestamp default NULL');
I want to set default NULL but i am unable to solve this and i am confused about this issue. your help need here
Try this
ALTER TABLE `insurance` CHANGE COLUMN `deleted_at`
`deleted_at` TIMESTAMP NULL DEFAULT NULL;
ALTER TABLE insurance CHANGE COLUMN deleted_at deletedAt timestamp default NULL
Is incorrect.
Use this please.
ALTER TABLE insurance MODIFY COLUMN deleted_at timestamp NULL DEFAULT NULL
The word deletedAt isn't a valid syntax. There is an error in your query.
I have table:
CREATE TABLE t1 (
id INT(3)
, datetime DATETIME(6)
);
I want to add default value to datetime column with fractional seconds:
ALTER TABLE 't1'
CHANGE 'datetime' 'datetime'
DATETIME DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6)
I get error message #1064:
1064 - 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 ''t1' CHANGE 'dt' 'dt' DATETIME DEFAULT CURRENT_TIMESTAMP(6) ON
UPDATE CURRENT_TI' at line 1
You need to use.
Without the qoutes around the table name and column name.
I've used backticks around datetime because datetime is a keyword in MySQL.
And you have forgotten that DATETIME needs to have that fractional seconds defined like DATETIME(6)
ALTER TABLE t1
CHANGE `datetime` `datetime`
DATETIME(6) DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6)
alter table `quote`
modify column `timestamp`
DEFAULT CURRENT_TIMESTAMP
ON UPDATE CURRENT_TIMESTAMP
NOT NULL
What's wrong with the above mysql query?
I am trying to change my timestamp column to default and update with the current timestamp.
#1064 - 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 'DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP NOT NULL' at line 1
After MODIFY COLUMN col_name the syntax requires a column_definition which in turn requires a type. Add the current type of this column (e.g. DATETIME) before DEFAULT to resolve the syntax error.
This is not so much an answer as it is a tip. In MySQL workbench 6.3 community build, if you want to modify the column using the table edit screen, make certain the "Data Type:" for your timestamp column is for sure set to TIMESTAMP and then make ON UPDATE CURRENT_TIMESTAMP the default value (on my screen, it is just below the "Data Type:").
I tried to add a column at end of the table assestbl
ALTER TABLE `assestbl` ADD `timestamp` VARCHAR NOT NULL DEFAULT CURRENT_TIMESTAMP
but its showing an error
1064 - 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 'NOT NULL DEFAULT CURRENT_TIMESTAMP' at line 1
You have two errors:
1) syntax error in datatype, varchar needs defined length: VARCHAR(LEN)
once you fix that you get something like invalid default value for 'timestamp':
2) DEFAULT CURRENT_TIMESTAMP can only be applied to temporal datatypes (DATE,TIME,DATETIME,TIMESTAMP and YEAR).
