+# clickhouse-client-cli
+
+A simple CLI tool that mimics `clickhouse-client` for executing SQL queries against a ClickHouse server.
+Uses the Java client-v2 API over HTTP, requests `TabSeparated` format, and streams raw output to stdout.
+
+## Build
+
+```bash
+cd tests/clickhouse-client
+mvn package -DskipTests
+```
+
+This produces an executable fat JAR at `target/clickhouse-client-cli-1.0.0.jar`.
+
+## Wrapper executable
+
+A wrapper script named `clickhouse-client` is provided in this directory.
+
+```bash
+cd tests/clickhouse-client
+./clickhouse-client --help
+```
+
+To call it as `clickhouse-client` from anywhere:
+
+```bash
+export PATH="$PATH:/home/schernov/workspace01/clickhouse-java/tests/clickhouse-client"
+clickhouse-client --help
+```
+
+## Usage
+
+Both `--option value` and `--option=value` formats are supported.
+
+### Query via `--query` / `-q`
+
+```bash
+./clickhouse-client -q "SELECT uniqExact(number) FROM numbers(1000)"
+```
+
+### Query via stdin
+
+Pipe a query:
+
+```bash
+echo "SELECT uniqExact(number) FROM numbers(1000)" | ./clickhouse-client
+```
+
+Here-string:
+
+```bash
+./clickhouse-client <<< "SELECT 1"
+```
+
+From a file:
+
+```bash
+./clickhouse-client < query.sql
+```
+
+If no `--query` is given and nothing is piped, the process blocks waiting for input.
+Type your SQL and press `Ctrl+D` (EOF) to execute.
+
+## Options
+
+| Option             | Default     | Description              |
+|--------------------|-------------|--------------------------|
+| `--host`, `-h`     | `localhost` | Server host              |
+| `--port`           | `8123`      | HTTP port                |
+| `--user`, `-u`     | `default`   | Username                 |
+| `--password`       | *(empty)*   | Password                 |
+| `--database`, `-d` | `default`   | Database                 |
+| `--query`, `-q`    |             | SQL query to execute     |
+| `--log_comment`    |             | Comment for query log    |
+| `--send_logs_level`|             | Send server logs level   |
+| `--max_insert_threads` |         | Server setting passthrough |
+| `--multiquery`     |             | Execute `;`-separated SQL statements |
+| `--secure`, `-s`   | off         | Use HTTPS                |
+| `--multiline`, `-n`|             | Ignored (compatibility)  |
+| `--help`           |             | Print usage              |
+
+Unknown long options in the form `--name value` / `--name=value` are also accepted and forwarded as ClickHouse server settings.
+Compatibility-only options used by tests are accepted but ignored.
+
+## Examples
+
+```bash
+# simple select
+./clickhouse-client -q "SELECT 1"
+
+# connect to a remote server with credentials
+./clickhouse-client \
+  --host ch.example.com --port 8443 --secure \
+  --user admin --password secret \
+  --log_comment "sync-job-42" \
+  --send_logs_level warning \
+  -q "SELECT count() FROM system.tables"
+
+# multi-line query from stdin
+./clickhouse-client <<'EOF'
+SELECT
+    database,
+    count() AS table_count
+FROM system.tables
+GROUP BY database
+ORDER BY table_count DESC
+EOF
+
+# multiquery from stdin (queries separated by ;)
+./clickhouse-client --multiquery <<'EOF'
+CREATE TEMPORARY TABLE t (x UInt8);
+INSERT INTO t VALUES (1), (2), (3);
+SELECT sum(x) FROM t;
+EOF
+```
