Question
Which DDL command is not used to modify the data type of a column in a table?a.ALTER COLUMNb.MODIFY COLUMNc.CHANGE COLUMNd.UPDATE COLUMN
Solution
The DDL (Data Definition Language) command that is not used to modify the data type of a column in a table is d. UPDATE COLUMN.
The UPDATE command in SQL is used to modify the existing records in a table, not to change the data type of a column.
On the other hand, ALTER COLUMN, MODIFY COLUMN, and CHANGE COLUMN are used in different SQL dialects to change the data type of a column. For example, ALTER COLUMN is used in MS SQL Server, MODIFY COLUMN is used in Oracle, and CHANGE COLUMN is used in MySQL.
