練習用 SQL
臨時朋友傳來一個訊息,要整理一下所有資料庫內有那些的資料表,就隨手寫了一下,有需要的朋友可以參考看看
DROP TABLE IF EXISTS #AllTables;
CREATE TABLE #AllTables (
DatabaseName sysname,
SchemaName sysname,
TableName sysname,
)
EXEC [sys].[sp_MSforeachdb] 'use [?];insert into #AllTables select "?",schema_name(schema_id),name from ?.sys.tables where type = "U" and "?" not in ("master","tempdb","msdb") ' ;
SELECT * FROM #AllTables
既然完成所有資料表 , 那也就順手把所有欄位也一併完成好了
DROP TABLE IF EXISTS #AllColumns;
CREATE TABLE #AllColumns (
DatabaseName sysname,
SchemaName sysname,
TableName sysname,
ColumnName sysname,
ColumnIndex int,
ColumnType sysname
)
EXEC [sys].[sp_MSforeachdb]
'use [?];insert into #AllColumns select "?",schema_name(t.schema_id),t.name, c.name, column_id, p.name
from sys.columns c
JOIN sys.tables t ON c.object_id = t.object_id
JOIN sys.types p ON c.user_type_id = p.user_type_id
where t.type = "U" and "?" not in ("master","tempdb","msdb") ORDER BY t.name,c.column_id ' ;
SELECT * FROM #AllColumns ORDER BY DatabaseName,SchemaName,TableName, ColumnIndex;
