查詢Adventureworks表的動態SQL

Question

我試圖從Sql Server 2008中的「Person」模式中查看Adventureworks數據庫中的表的列表。我開發了以下SP，但運行後如下，它給我錯誤「Incorrect語法靠近'）'「。你知道我該如何修改這個SP或exec聲明嗎？

CREATE PROCEDURE [getTableNames] 
@SchemaName VARCHAR(50) 
AS 

BEGIN 
SET NOCOUNT ON; 
SET @SchemaName = 'PERSON' 
DECLARE @cmd AS VARCHAR(max) 
SET @SchemaName = RTRIM(@SchemaName) 
SET @cmd = N'SELECT TABLE_NAME ' + 
'FROM information_schema.Tables ' + 
'WHERE TABLE_TYPE = ''BASE TABLE'' AND TABLE_SCHEMA = @SchemaName' 
END 

exec sp_executesql getTableNames, N'@SchemaName NVARCHAR(50), @SchemaName' 

Answer 1

你不需要動態SQL：

select * from sys.tables 
where type_desc = 'BASE TABLE' and schema_id = schema_id(@SchemaName) 

Answer 2

你實際上並不需要在這裏使用動態SQL，再加上因爲你不執行@cmd陳述你的存儲過程是不完全正確。只需使用：

CREATE PROCEDURE [getTableNames] 
@SchemaName VARCHAR(50) 
AS 
BEGIN 
    SET NOCOUNT ON 
    SELECT TABLE_NAME 
    FROM information_schema.Tables 
    WHERE TABLE_TYPE = 'BASE TABLE' AND TABLE_SCHEMA = @SchemaName 
END 

EXECUTE getTableNames 'PERSON'
