Hello I would like to know is is possible to drop all tables in database what was created under custom schema for example DBO1...with one sql query or special script.

Thanks

This will generate all the DROP TABLE statements for you and PRINT the SQL statement out. You can then validate it's what you expect before copying and executing. Just make sure you are 100% sure...maybe take a backup first :)

DECLARE @SqlStatement NVARCHAR(MAX)
SELECT @SqlStatement = 
    COALESCE(@SqlStatement, N'') + N'DROP TABLE [DBO1].' + QUOTENAME(TABLE_NAME) + N';' + CHAR(13)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'DBO1' and TABLE_TYPE = 'BASE TABLE'

PRINT @SqlStatement

The reason for this is because one table might have a column "CreatedDate" that you need to check if it's >30 days old, while another might have

Somewhat old thread I know, but I was looking for something like this and found the original answer very helpful. That said, the script will also try to drop views that might exist in that schema and give you an error message because you end up trying to drop a view by issuing a DROP TABLE statement.

I ended up writing this because I needed to drop all tables, views, procedures and functions from a given schema. Maybe not the most elegant way to accomplish this, but it worked for me and I thought I'd share.

Drop all tables for a given schema, Hi guys! Is there a quick way in T-SQL of dropping all the tables that are associated with a particular schema? I originally set about changing  Script to drop all objects of a Schema in SQL Server. I have spent almost 3 hours to complete this script and test it for couple of sample scenarios during this weekend (31/01/10). It drops all objects of a schema and then drops the schema itself.

Building on @Kevo's answer, I added the following for dropping all foreign key constraints before deleting the tables. I've only tested on SQL2008 R2

select @Sql = COALESCE(@Sql,'') + 'ALTER TABLE %SCHEMA%.' + t.name + ' drop constraint ' + 
OBJECT_NAME(d.constraint_object_id)  + ';' + CHAR(13)
from sys.tables t 
    join sys.foreign_key_columns d on d.parent_object_id = t.object_id 
    inner join sys.schemas s on t.schema_id = s.schema_id
where s.name = @Schema
ORDER BY t.name;

Get a List of all Tables In Oracle SQL, How do I drop all tables in a mysql schema? To change the schema owner from Sql Server Management Studio: Expand your database -> Security -> Schemas. In the Object Explorer Details you can see a list of the schemas and the owners: Right click on the schema that is owned by the user you want to delete and change the owner (Properties -> General -> Schema Owner).

Building on the other answers, here is a stored procedure spDropSchema that drops all objects in a schema and the schema itself.

Note that the procedure tries to drop sequence objects too, so it will only work on SQL Server 2012 and above.

IF EXISTS (SELECT * FROM sysobjects WHERE type = 'P' AND name = 'spDropSchema')
    BEGIN
        DROP  PROCEDURE  spDropSchema
    END
GO

CREATE PROCEDURE spDropSchema(@Schema nvarchar(200))
AS

DECLARE @Sql NVARCHAR(MAX) = '';

--constraints
SELECT @Sql = @Sql + 'ALTER TABLE '+ QUOTENAME(@Schema) + '.' + QUOTENAME(t.name) + ' DROP CONSTRAINT ' + QUOTENAME(f.name)  + ';' + CHAR(13)
FROM sys.tables t 
    inner join sys.foreign_keys f on f.parent_object_id = t.object_id 
    inner join sys.schemas s on t.schema_id = s.schema_id
WHERE s.name = @Schema
ORDER BY t.name;

--tables
SELECT @Sql = @Sql + 'DROP TABLE '+ QUOTENAME(@Schema) +'.' + QUOTENAME(TABLE_NAME) + ';' + CHAR(13)
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = @Schema AND TABLE_TYPE = 'BASE TABLE'
ORDER BY TABLE_NAME

ORDER BY TABLE_NAME

--procedures
SELECT @Sql = @Sql + 'DROP PROCEDURE '+ QUOTENAME(@Schema) +'.' + QUOTENAME(ROUTINE_NAME) + ';' + CHAR(13)

WHERE ROUTINE_SCHEMA = @Schema AND ROUTINE_TYPE = 'PROCEDURE'
ORDER BY ROUTINE_NAME

--functions
SELECT @Sql = @Sql + 'DROP FUNCTION '+ QUOTENAME(@Schema) +'.' + QUOTENAME(ROUTINE_NAME) + ';' + CHAR(13)

SELECT @Sql = @Sql + 'DROP SEQUENCE '+ QUOTENAME(@Schema) +'.' + QUOTENAME(SEQUENCE_NAME) + ';' + CHAR(13)

Deleting Multiple Records, How do I see all the tables created in SQL? In order to truncate all tables in your database you must first remove all the foreign key constraints, truncate the tables, and then restore all the constraints. The below script accomplishes this in an automated fashion, by executing the following steps: Create a table variable to store the constraint drop and creation scripts for the database.

I know this is an old thread but I think the easiest way to do this is by using the undocumented sp_MSforeachtable stored procedure:

EXEC sp_MSforeachtable
  @command1 = 'DROP TABLE ?'
, @whereand = 'AND SCHEMA_NAME(schema_id) = ''your_schema_name'' '

A detailed report on this stored procedure can be found here, but in case the link goes dead here are the highlights:

sp_MSforeachtable is a stored procedure that is mostly used to apply a T-SQL command to every table, iteratively, that exists in the current database. [...] realized that the question mark (?) it is used as the replacement of the table and during the execution it will be replaced by the appropriate table name.

@command1, @command2, @command3 sp_MSforeachtable stored procedure requires at least one command to be executed (@command1) but it allows up to 3 commands to be executed. Note that it will start to execute first the @command1 and then @command2 and @command3 by the last and this for each table.

@precommand Use this parameter to provide a command to be executed before the @command1. It is useful to set variable environments or perform any kind of initialization.

@postcommand Use this parameter to provide a command to be executed after all the commands being executed successfully. It is useful for control and cleanup processes.

@replacechar By default, a table is represented by the question mark (?) character. This parameter allows you to change this character.

@whereand By default, sp_MSforeachtable is applied to all user tables in the database. Use this parameter to filter the tables that you want to work with. On the next section, I will explain how you can filter the tables.

  • And if they really wanted to do it in one go, they could EXEC (or exec sp_executesql) @SqlStatement at the end.
  • @AdaTheDev for me this generated a list of drop statements in arbitrary order. I can not drop parents before the children for example. If you have foreign key constraints in place the script will not drop your tables. That is what i meant
  • @ladieu - ok gotcha foreign keys constraints, not all constraints That's true - with more jiggery pokery it could take ordering into account (or drop all FKs first)
  • If you want to execute this by EXEC or exec sp_executesql you'll need to change the @SqlStatement type to NVARCHAR.
  • You can drop all tables despite of foreign key constraints by executing this script sevaral times.
  • Sometimes you will have to deleted user defined types too. They are to be found with SELECT * FROM sys.types where is_user_defined = 1
