I am trying to get the row count and column count of all the tables in a schema in sql server using spark sql.
when I execute below query using sqoop, it's giving me the correct results.
sqoop eval --connect "jdbc:sqlserver://<hostname>;database=<dbname>" \
--username=<username> --password=<pwd> \
--query """SELECT
ta.name TableName ,
pa.rows RowCnt,
COUNT(ins.COLUMN_NAME) ColCnt FROM <db>.sys.tables ta INNER JOIN
<db>.sys.partitions pa ON pa.OBJECT_ID = ta.OBJECT_ID INNER JOIN
<db>.sys.schemas sc ON ta.schema_id = sc.schema_id join
<db>.INFORMATION_SCHEMA.COLUMNS ins on ins.TABLE_SCHEMA =sc.name and ins.TABLE_NAME=ta.name
WHERE ta.is_ms_shipped = 0 AND pa.index_id IN (1,0) and sc.name ='<schema>' GROUP BY sc.name, ta.name, pa.rows order by
TableName"""
But when I try to execute the same query from spark sql, I am getting an error that "com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'WHERE'" Please help me out, if anyone has an idea about this error.
Below is the spark sql command I executed spark-shell --jars "/var/lib/sqoop/sqljdbc42.jar"
sqlContext.read.format("jdbc").option("url", "jdbc:sqlserver://<hostname>;database=<dbname>;user=<user>;password=<pwd>").option("dbtable", """(SELECT
ta.name TableName ,pa.rows RowCnt,
COUNT(ins.COLUMN_NAME) ColCnt FROM <db>.sys.tables ta INNER JOIN
<db>.sys.partitions pa ON pa.OBJECT_ID = ta.OBJECT_ID INNER JOIN
<db>.sys.schemas sc ON ta.schema_id = sc.schema_id join
<db>.INFORMATION_SCHEMA.COLUMNS ins on ins.TABLE_SCHEMA =sc.name and ins.TABLE_NAME=ta.name

expected output:
TableName, RowCnt, ColCnt
table A, 62, 30
table B, 3846, 76
