Parameter Description

Parameter	Mandatory	Type	Description
fromJobConfig.useSql	Yes	Boolean	Whether to use the customized SQL statement to export data when exporting relational database data
fromJobConfig.sql	No	String	Customized SQL statement. CDM executes the SQL statement to export data.
fromJobConfig.schemaName	Yes	String	Database mode or tablespace. For example, public. NOTE: The parameter value can contain wildcard characters (), which is used to export all databases whose names start with a certain prefix or end with a certain suffix. The examples are as follows: SCHEMA indicates that all databases whose names starting with SCHEMA are exported. SCHEMA indicates that all databases whose names ending with SCHEMA* are exported. SCHEMA indicates that all databases whose names containing SCHEMA are exported.
fromJobConfig.tableName	Yes	String	Table name. For example, TBL_EXAMPLE. NOTE: The table name can contain wildcard characters (), which is used to export all tables whose names start with a certain prefix or end with a certain suffix. The number and types of fields in the tables must be the same. The examples are as follows: table indicates that all tables whose names starting with table are exported. table indicates that all tables whose names ending with table* are exported. table indicates that all tables whose names containing table are exported.
fromJobConfig.whereClause	No	String	WHERE clause used to specify the data to be extracted. If no WHERE clause is configured, the entire table will be extracted. For example, age > 18 and age <= 60.
fromJobConfig.columnList	No	String	List of fields to be extracted. Use & to separate field names. For example, id&gid&name.
fromJobConfig.partitionColumn	No	String	Partition field to be extracted, by which a job is split in multiple sub-jobs executed concurrently. For example, id.
fromJobConfig.incrMigration	No	Boolean	Whether to enable incremental data migration using MySQL Binlog. This can be only used for table/file migration from MySQL databases to GaussDB(DWS). If this function is enabled, data in the source table and destination table can be synchronized in real time. Each MySQL link or source table supports only one incremental migration job.
fromJobConfig.usePartition	No	Boolean	When data is exported from the Oracle database, data can be extracted from each partition in a partitioned table. When this function is enabled, you can use the fromJobConfig.partitionList parameter to specify the partitions in the Oracle table. This function does not support non-partitioned tables.
fromJobConfig.partitionList	No	String	Oracle table partitions to be migrated. Separate multiple partitions with ampersands (&). If you do not set this parameter, all partitions will be migrated.
