Describe table structure

Question

Which query will give the table structure with column definitions in SQL?

Answer 1

It depends from the database you use. Here is an incomplete list:

• sqlite3: .schema table_name
• Postgres (psql): \d table_name
• SQL Server: sp_help table_name (or sp_columns table_name for only columns)
• Oracle DB2: desc table_name or describe table_name
• MySQL: describe table_name (or show columns from table_name for only columns)
