Oracle query editor

Grafana provides a query editor for Oracle. Queries can contain macros which simplify syntax and allow for dynamic parts.

Query editor options

You can create a query directly in the query editor window. The Format as option allows you to query Oracle and return results as time series data or as a table. Click Show Help for a sample query, a list of macros and other helpful information to help you get started writing SQL queries.

Query as time series

When you set Format as to Time series, the query must return a column called time that returns either a SQL datetime data type or any numeric data type representing UNIX epoch time in seconds. Grafana interprets DATE and TIMESTAMP columns without an explicit timezone as UTC time. Any column except time and metric is treated as a value column. You can return a column named metric that is used as metric name for the value column.

Example with metric column:

sql Copy

SELECT
  $__timeGroup(time_date_time, '5m') AS time,
  MIN(value_double),
  'MIN' as metric
FROM test_data
WHERE $__timeFilter(time_date_time)
GROUP BY $__timeGroup(time_date_time, '5m')
ORDER BY time

Query as table

When you set the Format as query option to Table, you can create any type of SQL query. The table panel automatically shows the results of whatever columns and rows your query returns. You can change the name of a column by using the AS SQL command, which renames the column (or table) with an alias.

Macros

To simplify syntax and to allow for dynamic parts, like date range filters, you can add macros to your query.

The plugin also supports notation using curly brackets {}. Use this notation when queries are required inside parameters.

SQL Copy

$__timeGroup{dateColumn,'5m'}
$__timeGroup{SYS_DATE_UTC(SDATE),'5m'}
$__timeGroup{FROM_TZ(CAST(SDATE as timestamp), 'UTC'), '1h'}
