How to get the datatype of MySQL table columns?
You can get the MySQL table columns data type with the help of "information_schema.columns".
The syntax is as follows −
SELECT DATA_TYPE from INFORMATION_SCHEMA.COLUMNS where table_schema = 'yourDatabaseName' and table_name = 'yourTableName'
To understand the above syntax, let us first create a table −
mysql> create table DataTypeDemo −> ( −> Id int, −> Address varchar(200), −> Money decimal(10,4) −> ); Query OK, 0 rows affected (0.60 sec)
Apply the above syntax to get the MySQL columns data type. The query is as follows −
mysql> select data_type from information_schema.columns where table_schema = 'business' and able_name = 'DataTypeDemo';
The following is the output −
+-----------+ | DATA_TYPE | +-----------+ | int | | varchar | | decimal | +-----------+ 3 rows in set (0.00 sec)
If you want, include the column name as well in the output before the datatype. The query is as follows −
mysql> select column_name,data_type from information_schema.columns where table_schema = 'business' and table_name = 'DataTypeDemo';
The following output displays the column name corresponding to the data type −
+-------------+-----------+ | COLUMN_NAME | DATA_TYPE | +-------------+-----------+ | Id | int | | Address | varchar | | Money | decimal | +-------------+-----------+ 3 rows in set (0.00 sec)
