问题描述
我使用 spark-sql-2.4.1v 和 ojdbc6.jar 从 oracle 读取数据.
I'm using spark-sql-2.4.1v and ojdbc6.jar to read data from oracle.
有如下oracle表
create table schema1.modal_vals(
FAMILY_ID NOT NULL NUMBER,
INSERTION_DATE NOT NULL DATE,
ITEM_VALUE VARCHAR2(4000),
YEAR NUMBER,
QUARTER NUMBER,
LAST_UPDATE_DATE DATE
)
加载样本数据:
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-02","bbb-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-13","b+",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-17","bbb-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-13","bb",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-02","ccc-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-13","aa-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-OCT-13","a-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-03","bbb-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-13","b",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-FEB-03","aa+",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-13","aa+",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JAN-19","aaa+",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"30-JUN-18","ccc-",2013,2,null);
insert into modal_vals(FAMILY_ID,INSERTION_DATE,ITEM_VALUE,YEAR,QUARTER,LAST_UPDATE_DATE) values(2,"01-MAY-19","bb-",2013,2,null);
尝试将数据加载到 spark-sql 中，如下所示:
Try to load the data into spark-sql as below :
//please fill the respected oracle details
DataFrameReader ora_df_reader = spark.read().format("jdbc")
.option("url", o_url)
.option("driver", Constants.ORACLE_DRIVER)
.option("user", o_userName)
.option("password", o_passwd)
.option("fetchsize",1000);
Dataset<Row> ss = ora_df_reader
.option("inferSchema", true)
.option("schema","schema1")
.option("numPartitions", 20);
.option("partitionColumn", "INSERTION_DATE");
.option("lowerBound", "2002-03-31" )
.option("upperBound", "2019-05-01")
.option("dateFormat", "yyyy-MM-dd" )// Tried all "yyyy-mm-dd" ,"yyyy-MM-dd" "YYYY-MM-DD" "DD-MMM-YY" "dd-MMM-yy"
.option("dbtable", "select * from schema1.modal_vals")
.load();
我尝试不同方法时的错误:
尝试了 5ht-way:
.option("lowerBound", "2002-03-31 00:00:00");
.option("upperBound", "2019-05-01 23:59:59");
.option("timestampFormat", "yyyy-mm-dd hh:mm:ss");
.option("numPartitions", 240);
但给出错误:
java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd hh:mm:ss[.fffffffff]
at java.sql.Timestamp.valueOf(Timestamp.java:204)
at org.apache.spark.sql.execution.datasources.jdbc.JDBCRelation$.toInternalBoundValue(JDBCRelation.scala:179)
尝试了第二种方法:
.option("lowerBound","2002-03-31");
.option("upperBound", "2019-05-01");
.option("dateFormat", "yyyy-mm-dd");
我收到错误:
ORA-01861: 文字与格式字符串不匹配
ORA-01861: literal does not match format string
如何传递lower/upperBound"的日期?
How to pass the dates for "lower/upperBound"?
错误:
java.sql.SQLException: ORA-12801: error signaled in parallel query server P001(2)

根据此修复，据了解我们可以使用日期/时间戳作为分区列:https://issues.apache.org/jira/browse/SPARK-22814
As per this fix, it's understood we can use date/timestamp as the partition column: https://issues.apache.org/jira/browse/SPARK-22814
尝试了第二种方法:
.option("lowerBound","03/31/2002 00:00:00");
.option("upperBound", "05/01/2019 23:59:59");
.option("dateFormat", "mm/dd/yyyy hh:mm:ss");
java.lang.IllegalArgumentException
at java.sql.Date.valueOf(Date.java:143)
at org.apache.spark.sql.execution.datasources.jdbc.JDBCRelation$.toInternalBoundValue(JDBCRelation.scala:178)
尝试了第三种方式:
.option("lowerBound","03/31/2002");
.option("upperBound", "05/01/2019");
.option("dateFormat", "mm/dd/yyyy");
java.lang.IllegalArgumentException
at java.sql.Date.valueOf(Date.java:143)
at org.apache.spark.sql.execution.datasources.jdbc.JDBCRelation$.toInternalBoundValue(JDBCRelation.scala:178)
尝试了第四种方法:
option("lowerBound", "31.03.2002 00:00:00" );
option("upperBound", "01.05.2019 23:59:59");
option("dateFormat", "DD.MM.YYYY HH24:MI:SS")
java.lang.IllegalArgumentException在 java.sql.Date.valueOf(Date.java:143)在 org.apache.spark.sql.execution.datasources.jdbc.JDBCRelation$.toInternalBoundValue(JDBCRelation.scala:178)
java.lang.IllegalArgumentException at java.sql.Date.valueOf(Date.java:143) at org.apache.spark.sql.execution.datasources.jdbc.JDBCRelation$.toInternalBoundValue(JDBCRelation.scala:178)
推荐答案
如果我们在下面添加它将解决问题.
If we add below it will fix the issue.
option("sessionInitStatement", "ALTER SESSION SET NLS_DATE_FORMAT = 'YYYY-MM-DD'");
