將表從 MSSQL Server 加載到 Informix DB 時出錯

Question

我正在嘗試從 MSSQL - IBM Informix DB 加載表。 沒有主鍵的表正在加載，但沒有主鍵的表沒有加載並引發以下錯誤

Stream component 'st_2_Informix_Target' terminated
Stream component failed at subtask 2, component st_2_Informix_Target
Error executing data handler
Handling new table 'dbo'.'region3' failed
execute create primary key failed, statement ALTER TABLE dbo.region3 ADD CONSTRAINT region3_PK__region3__3213E83F82CE48A3 PRIMARY KEY ( id )
RetCode: SQL_ERROR  SqlState: 42000 NativeError: -201 Message: [Informix][Informix ODBC Driver][Informix]A syntax error has occurred.
Failed (retcode -1) to execute statement: 'ALTER TABLE dbo.region3 ADD CONSTRAINT region3_PK__region3__3213E83F82CE48A3 PRIMARY KEY ( id )'

Answer 1

有人（我猜是 SQLServer 或 DMS）正在嘗試使用在 Informix 中無效的 SQLServer SQL 語法向 Informix 表添加主鍵。

> ALTER TABLE dbo.region3 ADD CONSTRAINT region3_PK__region3__3213E83F82CE48A3 PRIMARY KEY ( id );

  201: A syntax error has occurred.
Error in line 1
Near character position 40

> ALTER TABLE dbo.region3 ADD CONSTRAINT  PRIMARY KEY ( id ) CONSTRAINT region3_PK__region3__3213E83F82CE48A3;

Table altered.

我建議在執行加載任務時檢查是否有任何選項可以禁用 PK 創建。
