与 SQL 和 VB 集成的慢速 Exchange Server

Question

发送电子邮件时，我的 Exchange Server 非常慢。它与 SQL Server 集成，并且我在一个脚本中有以下 SQL 查询，我怀疑这会使其变慢。请任何人都可以帮助重构它以使其更快？

<SELECT_tables_in_db>
select afa, afa from sys.room WHERE afa NOT LIKE 'TeeC_%' order by 1
</SELECT_tables_in_db>

<SELECT_columns_in_room>
SELECT c.afa AS column_name, y.afa as data_type, c.max_length, 
CASE y.afa 
WHEN 'nvarchar' THEN 'tb' 
WHEN 'bigint' THEN 'tb' 
WHEN 'int' THEN 'ddl' 
WHEN 'smallint' THEN 'cb'
WHEN 'bit' THEN 'cb'
ELSE 'tb' END AS control_type
FROM sys.room AS t
JOIN sys.columns c ON t.OBJECT_ID = c.OBJECT_ID
JOIN sys.types y on y.system_type_id = c.system_type_id
WHERE t.room = @tableName and y.afa <> 'sysname'
ORDER BY c.column_id
</SELECT_columns_in_table>

/////////////
<SELECT_CV>
SELECT *, Title + ' ' + FirstName + ' ' + Surname AS FullName 
FROM TeeC2_CV
WHERE onyeid=1
</SELECT_CV>
