Sql Solutions
Solution 1 - Sql
sp_help tablename in sql server -- sp_help [ [ @objname = ] 'name' ]
desc tablename in oracle -- DESCRIBE { table-Name | view-Name }
Solution 2 - Sql
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(orsp_columns table_namefor only columns) - Oracle DB2:
desc table_nameordescribe table_name - MySQL:
describe table_name(orshow columns from table_namefor only columns)
Solution 3 - Sql
In MySQL you can use DESCRIBE <table_name>
Solution 4 - Sql
select * from INFORMATION_SCHEMA.COLUMNS where TABLE_NAME='<Table Name>'
You can get details like column datatype and size by this query
Solution 5 - Sql
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'student'
Solution 6 - Sql
DESCRIBE tableName
Check MySQL describe command
Solution 7 - Sql
Highlight table name in the console and press ALT+F1
Solution 8 - Sql
For Sybase aka SQL Anywhere the following command outputs the structure of a table:
DESCRIBE 'TABLE_NAME';
Solution 9 - Sql
For SQL Server use exec sp_help
USE db_name;
exec sp_help 'dbo.table_name'
For MySQL, use describe
DESCRIBE table_name;
Solution 10 - Sql
For SQL, use the Keyword 'sp_help'
Solution 11 - Sql
This depends on your database vendor. Mostly it's the "information schema" you should Google for (applies to MySQL, MSSQL and perhaps others).
Solution 12 - Sql
Sql server
DECLARE @tableName nvarchar(100)
SET @tableName = N'members' -- change with table name
SELECT
[column].*,
COLUMNPROPERTY(object_id([column].[TABLE_NAME]), [column].[COLUMN_NAME], 'IsIdentity') AS [identity]
FROM
INFORMATION_SCHEMA.COLUMNS [column]
WHERE
[column].[Table_Name] = @tableName
Solution 13 - Sql
In DBTools for Sybase, it's sp_columns your_table_name.
