Drop all table

[Sabrina]

Hi everybody,

I need some help in SQL Server. I am looking for a command that will "Drop
all user table" in a
user database.

Can anyone help me?

Thank you very much

To add to Erland's response, below is a script developed for SQL 2000
that will drop schema bound views and functions as sell as foreign keys
beforehand. This will still need to be run iteratively in the case of
nested schema bound objects.

IF DB_NAME() IN ('master', 'msdb', 'model', 'distribution')
BEGIN
RAISERROR('Not for use on system databases', 16, 1)
GOTO Done
END

SET NOCOUNT ON

DECLARE @DropStatement nvarchar(4000)
DECLARE @SequenceNumber int
DECLARE @LastError int
DECLARE @TablesDropped int

DECLARE DropStatements CURSOR LOCAL FAST_FORWARD READ_ONLY FOR
--views
SELECT
1 AS SequenceNumber,
N'DROP VIEW ' +
QUOTENAME(TABLE _SCHEMA) +
N'.' +
QUOTENAME(TABLE _NAME) AS DropStatement
FROM
INFORMATION_SCH EMA.TABLES
WHERE
TABLE_TYPE = N'VIEW' AND
OBJECTPROPERTY(
OBJECT_ID(QUOTE NAME(TABLE_SCHE MA) +
N'.' +
QUOTENAME(TABLE _NAME)),
'IsSchemaBound' ) = 1 AND
OBJECTPROPERTY(
OBJECT_ID(QUOTE NAME(TABLE_SCHE MA) +
N'.' +
QUOTENAME(TABLE _NAME)),
'IsMSShipped') = 0
UNION ALL
--procedures and functions
SELECT
2 AS SequenceNumber,
N'DROP PROCEDURE ' +
QUOTENAME(ROUTI NE_SCHEMA) +
N'.' +
QUOTENAME(ROUTI NE_NAME) AS DropStatement
FROM
INFORMATION_SCH EMA.ROUTINES
WHERE
ROUTINE_TYPE = N'FUNCTION' AND
OBJECTPROPERTY(
OBJECT_ID(QUOTE NAME(ROUTINE_SC HEMA) +
N'.' +
QUOTENAME(ROUTI NE_NAME)),
'IsSchemaBound' ) = 1 AND
OBJECTPROPERTY(
OBJECT_ID(QUOTE NAME(ROUTINE_SC HEMA) +
N'.' +
QUOTENAME(ROUTI NE_NAME)),
'IsMSShipped') = 0
UNION ALL
--foreign keys
SELECT
3 AS SequenceNumber,
N'ALTER TABLE ' +
QUOTENAME(TABLE _SCHEMA) +
N'.' +
QUOTENAME(TABLE _NAME) +
N' DROP CONSTRAINT ' +
CONSTRAINT_NAME AS DropStatement
FROM
INFORMATION_SCH EMA.TABLE_CONST RAINTS
WHERE
CONSTRAINT_TYPE = N'FOREIGN KEY'
UNION ALL
--tables
SELECT
4 AS SequenceNumber,
N'DROP TABLE ' +
QUOTENAME(TABLE _SCHEMA) +
N'.' +
QUOTENAME(TABLE _NAME) AS DropStatement
FROM
INFORMATION_SCH EMA.TABLES
WHERE
TABLE_TYPE = N'BASE TABLE' AND
OBJECTPROPERTY(
OBJECT_ID(QUOTE NAME(TABLE_SCHE MA) +
N'.' +
QUOTENAME(TABLE _NAME)),
'IsMSShipped') = 0
ORDER BY SequenceNumber

OPEN DropStatements
WHILE 1 = 1
BEGIN
FETCH NEXT FROM DropStatements INTO @SequenceNumber , @DropStatement
IF @@FETCH_STATUS = -1 BREAK
BEGIN
RAISERROR('%s', 0, 1, @DropStatement) WITH NOWAIT
--EXECUTE sp_ExecuteSQL @DropStatement
SET @LastError = @@ERROR
IF @LastError > 0
BEGIN
RAISERROR('Scri pt terminated due to unexpected error', 16, 1)
GOTO Done
END
END
END
CLOSE DropStatements
DEALLOCATE DropStatements

Done:

GO

Hope this helps.
