在SQL存储过程中创建临时表

Posted 2021-02-26

A Temp table is great for combining multiple SELECT statements in a Sproc and outputting as just one table.

Don't forget to Drop the table after the SELECT * FROM #TempTableName at the end.

CREATE TABLE #TableName(
ID INT,
FieldName nVarChar(30) )
 
INSERT INTO #TableName (ID, FieldName)
SELECT 	ID, FieldName
FROM 	dbo.TableName
WHERE 	TYPE = 'Value'
 
-- Do some stuff with the table
 
DROP TABLE #TableName
 
 
-------------------------------------------------------
 
FOR Multiple Queries repeat the INSERT INTO statement
 
CREATE TABLE #TableName(
ID INT,
FieldName nVarChar(30) )
 
INSERT INTO #TableName (ID, FieldName)
SELECT 	ID, FieldName
FROM 	dbo.TableName
WHERE 	TYPE = 'Value'
 
INSERT INTO #TableName (ID, FieldName)
SELECT 	ID, FieldName
FROM 	dbo.TableName
WHERE 	TYPE = 'Value'
 
-- Do some stuff with the table eg SELECT * From #TableName
 
DROP TABLE #TableName
