Fetch DAFAULT Value from MySQL Table

September 16, 2014 By Kamalika Leave a Comment

Fetch DEFAULT value from MySQL table or MySQL get DEFAULT value for Column or How to SELECT DEFAULT value of a field or How Can I get back DEFAULT values for Column names in a MySQL Table.

We can fetch the column names in a MySQL Table fairly easily by the simple command:

[bash]

DESC tbl_admin_modules;

[/bash]DESC tablename MySQL

But is there a way to retrieve the default data value for each column in a MySQL Table? As per the Stackoverflow link there is a little complex way but I figured out two simpler ways to do the same.

Method 1:

Syntax

[bash]

SHOW FULL COLUMNS FROM tablename;

[/bash]

Example

[bash]

SHOW FULL COLUMNS FROM tbl_admin_modules;

[/bash]

SHOW FULL COLUMNS FROM tablename MySQL

Method 2:

Syntax

[bash]

SELECT COLUMN_DEFAULT
FROM information_schema.COLUMNS
WHERE
table_name = ‘tablename’
AND column_name = ‘columnname’;

[/bash]

Example

[bash]

SELECT COLUMN_DEFAULT
FROM information_schema.COLUMNS
WHERE
table_name = ‘tbl_admin_modules’
AND column_name = ‘active’;

[/bash]
