Parameter description

Table 1 Parameter description

Parameter

Description

DLI_TABLE

Name of the DLI table for which a datasource connection has been created.

DLI_TEST

indicates the table that contains the data to be queried.

field1,field2..., field

Column values in the DLI_TEST table must match the column values and types in the DLI_TABLE table.

where_condition

Query condition.

num

Limit the query result. The num parameter supports only the INT type.

values_row

Value to be inserted to a table. Use commas (,) to separate columns.

Precautions

  • The target DLI table must exist.
  • When creating a DLI table, you need to specify the schema information.
  • If key.column is specified during table creation, the value of the specified field is used as a part of the Redis key name. The following is an example: 
    1

    create table test_redis(name string, age int) using redis options(
  'host' = '192.168.4.199',
  'port' = '6379',
  'password' = '******',
  'table' = 'test_with_key_column',
  'key.column' = 'name'
);
insert into test_redis values("James", 35), ("Michael", 22);

    The Redis database contains two tables, naming test_with_key_column:James and test_with_key_column:Michael respectively.

  • If key.column is not specified during table creation, the key name in Redis uses the UUID. The following is an example: 
    1

    create table test_redis(name string, age int) using redis options(
  'host' = '192.168.7.238',
  'port' = '6379',
  'password' = '******',
  'table' = 'test_without_key_column'
);
insert into test_redis values("James", 35), ("Michael", 22);

    In Redis, there are two tables named test_without_key_column:uuid.

INSERT INTO test_redis
  VALUES("James", 35), ("Michael", 22);
