How to extract column name and type from MySQL?

To extract column name and type, use INFORMATION_SCHEMA.COLUMNS −

select concat(column_name,'=',data_type) as anyAliasName from information_schema.columns where table_schema= yourDatabaseName and table_name= yourTableName;

Let us first create a table −

mysql> create table DemoTable1812      (      Id int,      FirstName varchar(20),      Age int,      isMarried boolean,      status ENUM('ACTIVE','INACTIVE')      ); Query OK, 0 rows affected (0.00 sec)

Here is the query to extract column name and type from MySQL:

mysql> select concat(column_name,'=',data_type) as COLUMNNAMEANDTYPE from information_schema.columns      where table_schema= 'web' and table_name= 'DemoTable1812';

This will produce the following output −

+-------------------+ | COLUMNNAMEANDTYPE | +-------------------+ | Id=int            | | FirstName=varchar | | Age=int           | | isMarried=tinyint | | status=enum       | +-------------------+ 5 rows in set (0.00 sec)
