def recreateTableFromParquetDDLs(tableName: String, path: String, partitionColumns: Seq[String] = Seq.empty): Seq[String]

Recreate a table from parquet files, inferring the schema from the parquet.
Recreate a table from parquet files, inferring the schema from the parquet. Table is dropped if it exists and then recreated.
tableName
name of the table
path
path of the table location
partitionColumns
optional list of partition columns
returns
the sql statements which need executing to perform the table recreation

def updateTableParquetLocationDDLs(tableName: String, path: String, partitionColumns: Seq[String] = Seq.empty): Seq[String]

Update the data location of a parquet table.
Update the data location of a parquet table. If the table is partitioned, it will be dropped if it exists and recreated. If the table is not partitioned and forceRecreateTables is true, it will be dropped if it exists and recreated. If the table is not partitioned and forceRecreateTables is false, then the data location will be changed without dropping the table. The table will be created if it does not already exist.
tableName
name of the table
path
path of the table location
partitionColumns
optional list of partition columns
returns
the sql statements which need executing to perform the table update
