转向键值对以与另一台服务器上的值进行一致性测试。我遇到了返回错误的问题。

列“type”的类型与 UNPIVOT 列表中指定的其他列的类型冲突。
询问:
SELECT
sourceUnpivoted.idServer,
sourceUnpivoted.sourceServerName,
sourceUnpivoted.name,
sourceUnpivoted.columnName,
sourceUnpivoted.columnValue
FROM (
SELECT
CAST('1' AS VARCHAR(255)) AS idServer,
CAST('thisOne' AS VARCHAR(255)) AS sourceServerName,
CAST('theDatabase' AS VARCHAR(255)) AS sourceDatabaseName,
CAST(name AS VARCHAR(255)) AS name,
CAST(object_id AS VARCHAR(255)) AS object_id,
CAST(principal_id AS VARCHAR(255)) AS principal_id,
CAST(schema_id AS VARCHAR(255)) AS schema_id,
CAST(parent_object_id AS VARCHAR(255)) AS parent_object_id,
CAST(type AS VARCHAR(255)) AS type,
CAST(type_desc AS VARCHAR(255)) AS type_desc,
CAST(create_date AS VARCHAR(255)) AS create_date,
CAST(lock_escalation_desc AS VARCHAR(255)) AS lock_escalation_desc
...
FROM noc_test.dbo.stage_sysTables
) AS databaseTables
UNPIVOT (
columnValue FOR columnName IN (
object_id,
principal_id,
schema_id,
parent_object_id,
type,
type_desc,
create_date,
lock_escalation_desc
)
) AS sourceUnpivoted
为什么这不喜欢[type]
, [type_desc]
, [lock_escalation_desc]
??? 我也试过CONVERT(VARCHAR(255),type) AS type
