hbase_scan()
描述：
查询hbase数据库中的数据，结果值返回游标或者序表
语法：
hbase_scan(client,tableName,rowName,family:column:type:alias,family2:column2:type:alias2,...;rowPrefix:x,filter:f,startRow:startrow,stopRow:stoprow,timeRange:[t1,t2],timeStamp:t)
备注：
外部库函数，通过habse_scan函数获取hbase数据库中的数据，默认返回序表，使用@c选项时返回游标。
选项：
|
@c |
返回游标 |
参数：
|
client |
数据库连接信息 |
|
tableName |
表名 |
|
rowName |
行键类型 |
|
family |
列族名 |
|
column |
列名 |
|
Type |
类型，可省略 |
|
alias |
列别名，可省略 |
|
rowPrefix:x |
‘rowPrefix:’为固定写法，参数x为rowKey前缀 |
|
filter:f |
filter句柄 |
|
startRow:startrow |
‘startRow:’是固定写法，参数startrow为起始行，截取的数据包含改行 |
|
stopRow:stoprow |
‘stopRow:’是固定写法，参数stoprow为结束行，截取的数据不包含改行 |
|
timeRange:[t1,t2] |
“timeRange:[,]”是固定写法，t1为起始时间戳，取出的数据包含t1的value值，t2为结束时间戳，取出的数据不包含t1的value值 |
|
timeStamp:t |
时间戳 |
返回值：
序表或游标
示例：
|
|
A |
|
|
1 |
=hbase_open("hdfs://192.168.0.8:9000", "192.168.0.8:2181") |
|
|
2 |
=hbase_scan(A1,"emp") |
查询表中所有数据 |
|
3 |
=hbase_scan@c(A1,"emp") |
返回游标 |
|
4 |
=A3.fetch() |
|
|
5 |
=hbase_filter("SingleColumnValueFilter","family","tel","=",hbase_cmp@s("13")) |
|
|
6 |
=hbase_scan(A1,"emp";filter:A5) |
返回A5单元格过滤出的数据 |
|
7 |
=hbase_scan(A1,"emp","company:name":string:cname,"company:position":string:cpos,"family:tel":string;filter:A5,startRow:row3,stopRow:row7) |
从A5单元格中过滤的数据中取row3到row7行的数据，不包含row7行 |
|
8 |
=hbase_scan(A1,"emp","company:name":string:cname,"company:position":string:cpos,"family:tel":string;filter:A5,rowPrefix:row1) |
从A5单元格中过滤的数据中取出rowKey前缀为row1的行 |
|
9 |
=hbase_scan(A1,"emp","company:name":string:cname,"company:position":string:cpos,"family:tel":string;filter:A5,startRow:row3,stopRow:row7,timeStamp:1488855958071) |
|
|
10 |
=hbase_scan(A1,"emp","company:name":string:cname,"company:position":string:cpos,"family:tel":string;filter:A5,startRow:row3,stopRow:row7,timeRange:[1488855958071,1488855958255]) |
