> I am using update functionality with the *rand(1)* and *rand()* which return deterministic value or random value.
> But as I run query it gives error.
> *Create Table :* CREATE TABLE uniqdata (CUST_ID int,CUST_NAME String,ACTIVE_EMUI_VERSION string, DOB timestamp, DOJ timestamp, BIGINT_COLUMN1 bigint,BIGINT_COLUMN2 bigint,DECIMAL_COLUMN1 decimal(30,10), DECIMAL_COLUMN2 decimal(36,10),Double_COLUMN1 double, Double_COLUMN2 double,INTEGER_COLUMN1 int) STORED BY 'org.apache.carbondata.format' TBLPROPERTIES ("TABLE_BLOCKSIZE"= "256 MB");
> *Load Data :* LOAD DATA INPATH 'hdfs://localhost:54310/2000_UniqData.csv' into table uniqdata OPTIONS ('DELIMITER'=',' ,'QUOTECHAR'='""','BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,ACTIVE_EMUI_VERSION,DOB,DOJ,BIGINT_COLUMN1,BIGINT_COLUMN2,DECIMAL_COLUMN1,DECIMAL_COLUMN2,Double_COLUMN1,Double_COLUMN2,INTEGER_COLUMN1','MAXCOLUMNS'='12');
> *Query-1 :* Update uniqdata set (decimal_column1) = (rand());
