  CREATE DATABASE a;
  EOF

• ✔️ CREATE TABLE

  cat <<EOF | curl -X POST http://a:b@localhost:8123/?database=a --data-binary @-
  CREATE TABLE IF NOT EXISTS time_series  (date Date,fingerprint UInt64,labels String, name String)
  ENGINE = ReplacingMergeTree(date) PARTITION BY date ORDER BY fingerprint;
  EOF

• ✔️ INSERT DATA

  
  cat <<EOF | curl -X POST 'http://a:b@localhost:8123/?query=INSERT%20INTO%20a.time_series(date,%20fingerprint,%20labels,%20name)%20FORMAT%20JSONEachRow' --data-binary @-
  {"fingerprint":"15239659101592556481","timestamp_ns":"1699265700000000000","value":null,"string":"FREQ_TEST_0"}

EOF

- ❌  INSERT AGAIN

cat <<EOF | curl -X POST 'http://a:b@localhost:8123/?query=INSERT%20INTO%20a.time_series(date,%20fingerprint,%20labels,%20name)%20FORMAT%20JSONEachRow' --data-binary @- {"fingerprint":"15239659101592556482","timestamp_ns":"1699265700000000000","value":null,"string":"FREQ_TEST_0"}
