Syntax error or access violation: 1064 You have an
error in your SQL syntax; check the manual that
corresponds to your MariaDB server version for the right syntax to use near
'deletedAt timestamp default NULL' at
line 1
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.

SQL Statement:
ALTER TABLE `Trade`.`details`
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`
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)
`effective_end_utc` timestamp NOT NULL COMMENT 'The UTC timestamp for when the target ceases to be in effect.',
This will end up giving me
ERROR 1067 (42000) at line 27: Invalid default value for 'effective_end_utc'
Base on other reponse, I have even set the mode to following at the begining of schema
SET GLOBAL SQL_MODE='ALLOW_INVALID_DATES'
Any idea whats going wrong?
The schema should be changed with a default value like
`reported_timestamp_utc` timestamp NULL DEFAULT NULL COMMENT
I have to add a column whose default value is not null by default to the table after particular column using Alter table.
ALTER TABLE tblechecklistrevision ADD COLUMN IWorkFlowOrder INT(10) DEFAULT NOT NULL AFTER fState;
When I Execute the query I will get the below error
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 AFTER fState' at line 1
You should remove DEFAULT:
ALTER TABLE tblechecklistrevision
ADD COLUMN IWorkFlowOrder INT(10) NOT NULL AFTER fState;
DEFAULT is for setting initial value to new rows where a value for that column isn't specified, when you write ...INT(10) NOT NULL what you mean is actually that that column can never contain a NULL, not only at initialization time.
If you want the default value not to equal NULL (example 0) you can do:
ALTER TABLE tblechecklistrevision
ADD COLUMN IWorkFlowOrder INT(10) NOT NULL DEFAULT 0 AFTER fState
Hey guys I was trying to alter my tables column to take
the current time stamp on creation, the error I'm getting
is #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 '( 'inspection_number' NOT NULL default CURRENT_TIMESTAMP )' at line 1
I was trying to use
ALTER TABLE `reports` (
`inspection_number` DATE NOT NULL default CURRENT_DATE
);
But I"m not seeing the error?
Seems syntax is not correct. Use below :
if adding new column inspection_number:
ALTER TABLE `reports` ADD COLUMN `inspection_number` timestamp NOT NULL default CURRENT_TIMESTAMP
if modifying existing inspection_number column:
ALTER TABLE `reports` MODIFY COLUMN `inspection_number` timestamp NOT NULL default CURRENT_TIMESTAMP
Please specify datatype of column
You're missing a MODIFY
ALTER TABLE `reports` (
MODIFY `inspection_number` NOT NULL default CURRENT_TIMESTAMP
);
ALTER TABLE `reports`
MODIFY `inspection_number` TIMESTAMP NOT NULL default CURRENT_TIMESTAMP ;
The syntax you have there is for when you create a table. When you modify a table and want to set a default value use:
ALTER TABLE table_name MODIFY col_name col_type NOT NULL DEFAULT CURRENT_TIMESTAMP;
