CURRENT_DATE/CURDATE() not working as default DATE value

Pretty straight forward question here, I think this should work but it doesn't. Why doesn't it?

CREATE TABLE INVOICE(
   INVOICEDATE DATE NOT NULL DEFAULT CURRENT_DATE
)

According to this documentation, starting in MySQL 8.0.13, you will be able to specify:

CREATE TABLE INVOICE(
    INVOICEDATE DATE DEFAULT (CURRENT_DATE)
)

MySQL 8.0.13 was released to General Availability in October 2018. The release info is located here.

Currently from MySQL 8 you can set the following to a DATE column:

In MySQL Workbench, in the Default field next to the column, write: (curdate())

If you put just curdate() it will fail. You need the extra ( and ) at the beginning and end.

I have the current latest version of MySQL: 8.0.20

So my table name is visit, my column name is curdate.

alter table visit modify curdate date not null default (current_date);

This writes the default date value with no timestamp.

Support for DEFAULT with expressions (MDEV-10134).

----- 2018-10-22 8.0.13 General Availability -- -- -----

MySQL now supports use of expressions as default values in data type specifications. This includes the use of expressions as default values for the BLOB, TEXT, GEOMETRY, and JSON data types, which previously could not be assigned default values at all. For details, see Data Type Default Values.

I came to this page with the same question in mind, but it worked for me!, Just thought to update here , may be helpful for someone later!!

While creating a table, you have to use CURRENT_DATE() function as default value. Please see below example I just tested.

CREATE TABLE SALES_DATA (
    SALES_ID INT UNSIGNED NOT NULL AUTO_INCREMENT,
    SALES_GIRL_ID INT UNSIGNED NOT NULL,
    SALES_DATE DATE NOT NULL DEFAULT (CURRENT_DATE()),
    TOTAL_SALES FLOAT(6, 2),
    PRIMARY KEY (SALES_ID),
    FOREIGN KEY (SALES_GIRL_ID) REFERENCES SALES_GIRLS(ID)
);
