Table Operation

Query Table Information

Like Mysql's information_schema.tables, HoraeDB provides system.public.tables to save tables information. Columns:

• timestamp([TimeStamp])
• catalog([String])
• schema([String])
• table_name([String])
• table_id([Uint64])
• engine([String])

Example

Query table information via table_name like this:

curl --location --request POST 'http://localhost:5000/sql' \
--header 'Content-Type: application/json' \
-d '{
    "query": "select * from system.public.tables where `table_name`=\"my_table\""
}'

Response

{
    "rows":[
        {
            "timestamp":0,
            "catalog":"horaedb",
            "schema":"public",
            "table_name":"my_table",
            "table_id":3298534886446,
            "engine":"Analytic"
        }
}
