Initial JDBC Bridge catalog version. Hands-free Maven JAR download. Auth Notes and SQL examples for ODBC apps. Apache IoTDB (tree) JDBC from Power BI, SQL Server Linked Server via ZappySys Data Gateway, Crystal Reports, SSRS, Azure Data Factory, and other ODBC tools.

1. Note the IoTDB host and RPC port (default 6667).
2. Create a user in IoTDB (CREATE USER) or use root in a lab only.
3. Tree model uses path-style time series. Switch to Table dialect Auth if you enabled table SQL.
4. Finish the wizard. Then click Test Connection on the DSN Main UI (the wizard does not run Test Connection).
5. Done. You can query from C#, Python, PowerShell, and ODBC apps.

]]> Apache IoTDB (table) JDBC from Power BI, SQL Server Linked Server via ZappySys Data Gateway, Crystal Reports, SSRS, Azure Data Factory, and other ODBC tools.

1. Same host/port as tree. Append sql_dialect=table (already in this URL).
2. Fill user and password. Table dialect uses SHOW TABLES / relational SQL.
3. Finish the wizard. Then click Test Connection on the DSN Main UI (the wizard does not run Test Connection).
4. Done. You can query from C#, Python, PowerShell, and ODBC apps.

]]> Lists tables available to this connection. Use this in Power BI or a SQL Server Linked Server to confirm the catalog before building reports.

]]> Returns rows from root.sg.d1. Replace the identifier with your catalog object. Works in Excel, SSRS, and Crystal Reports.

]]> Returns matching rows from root.sg.d1. Swap the column and literal for your schema.

]]> Joins two tables on a key. Use in Azure Data Factory or SSIS when you need a combined extract.

]]> Counts rows per group. Typical Power BI import pattern before a visual.

]]> Keeps groups whose count is at least 10.

]]> = 10]]> Returns the first 100 rows ordered by a column. Useful for preview in Excel or Crystal Reports.

]]> Returns the number of rows in root.sg.d1.

]]> Maps a column to labels with CASE.

]]> Returns a column list instead of star. Prefer this in Linked Server views.
