SQOOP --query with SCHEMA in SQL Server - hive

Question

I'm trying to use the --query option in sqoop to import data from SQL Server. My concern is, how can we declare which schema to use with --query in SQL Server.
My script:
sqoop \
--options-file sqoop/aw_mssql.cfg \
--query "select BusinessEntityId, LoginID, cast(OrganizationNode as string) from Employee where \$CONDITIONS" \
--hive-table employees \
--hive-database mssql \
-- --schema=HumanResources
Still produces an error
Invalid object name 'Employee'
Also tried
--connect "jdbc:sqlserver://192.168.1.17;database=AdventureWorks;schema=HumanResources"
but that also failed.

Answer 1

You can try this below code:
sqoop import \
--connect jdbc:sqlserver://192.168.1.17;database=AdventureWorks \
--username "Your User" \
--password "Your Password" \
--driver com.microsoft.sqlserver.jdbc.SQLServerDriver \
--verbose \
--query "select BusinessEntityId, LoginID, cast(OrganizationNode as string) from HumanResources.Employee where \$CONDITIONS" \
--split-by "EmpID" \
--where " EmpID='Employee ID' " \
-m 1 \
--target-dir /user/cloudera/ingest/raw/Employee\
--fields-terminated-by "," \
--hive-import \
--create-hive-table \
--hive-table mssql.employees \
hive-import – Import table into Hive (Uses Hive’s default delimiters
if none are set.)
create-hive-table – It will create new HIBE table. Note: Job
will be failed if a Hive table already exists. It works in this
case.
hive-table – Specifies <db_name>.<table_name>.

The sqoop command you are using is missing a few things. 1st of all you need to specify that this is an sqoop import job. apart from that your query needs to have a connection string. Moreover i dont know what argments you are passing inside the options file so if you had posted the details it would have been easier and i am not sure about the -- --schema=HumanResources thing as i haven't seen it. A correct working sqoop example query is :
sqoop import --connect <connection string> --username <username> --password <password> --query <query> --hive-import --target-table <table_name> -m <no_if_mappers
Moreover keep this in mind while using --query tool you need not specify the --table tool, otherwise it will throw an error.

-schema can work in conjunction with -table, but not with -query. Think what would that mean, it would require to parse the text of the query and replace every unqualified table reference with a two-part name, but not table references that are already two-part, three-part or four-part names. And match exactly the syntax rules of the back end (SQL Server in this case). It's just not feasible.
Specify the schema explicitly in the query:
select BusinessEntityId, LoginID, cast(OrganizationNode as string)
from HumanResources.Employee
where ...
