Execution Example

GridDB Server need to be started in advance.

  1. Create a container

     #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers 
 $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
 '{"container_name":"test", "container_type":"COLLECTION", "rowkey":true, 
 "columns":[{"name":"col1", "type":"STRING", "index":["TREE"]}, 
   {"name":"col2", "type":"INTEGER"}, {"name":"col3", "type":"BOOL"}]}' 
 http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers

  2. Append a row data

     #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers/[containerName]/rows 
 $ curl -X PUT --basic -u admin:admin -H "Content-type:application/json" -d 
 '[["value", 1, true]]' 
 http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers/test/rows

  3. Get a row data

     #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers/[containerName]/rows 
 $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
 '{"limit":1000}'
 http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers/test/rows 
 --> {"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
       {"name":"col3","type":"BOOL"}],"rows":[["value",1,true]],"offset":0,"limit":1000,"total":1}

  4. Query with TQL

     #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/tql 
 $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
 '[{"name":"test", "stmt":"select *", "columns":[]}]' 
 http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/tql 
 --> [{"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
        {"name":"col3","type":"BOOL"}],"results":[["value",1,true]],"offset":0,"limit":1000000,"total":1}]

  5. Query with SQL

     #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/sql/select 
 $ curl -X POST -u admin:admin -H "Content-type:application/json; charset=UTF-8" 
 -d '[{"stmt":"select * from test"}]' 
 http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/sql/dml/query 
 --> [{"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
        {"name":"col3","type":"BOOL"}],"results":[["value",1,true]]}]

 Note: "/:cluster/dbs/:database/sql/select" style is not recommended.

  6. Update with SQL

     #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/sql/update 
 $ curl -X POST -u admin:admin -H "Content-type:application/json; charset=UTF-8" 
 -d '[{"stmt":"update test set col3 = false where col2 = 1"}]' 
 http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/sql/dml/update 
 --> [{"status":1, "updatedRows":1,
        "stmt":"update test set col3 = false where col2 = 1", "message":null}]
