Kyle Brandt	c6e52c4766	SQL Expressions: Make SQL Expressions work with Alerting (#101820) ... Initial support for alerting with SQL expressions - When `format` is set to `alerting`, SQL expressions output in a format suitable for alerting evaluation. - Outstanding TODOs: - Deduplicate output rows - Add more tests - Fix broken alerting UI rendering (likely due to shape change to undocumented full-long format) - Basic usage: - SQL must return one numeric column and one or more string columns. - Each row may become an alert. - The alert fires if the numeric value is non-zero. - String columns are treated as labels. --------- Co-authored-by: Konrad Lalik <konradlalik@gmail.com> Co-authored-by: Tom Ratcliffe <tom.ratcliffe@grafana.com> Co-authored-by: Sam Jewell <sam.jewell@grafana.com>	4 months ago

Sam Jewell	c9e929e2e6	SQL Expressions: Allow more MySQL AST node-types (#102973) ... * SQL Expressions: Add Null-literal node * Retain some order in the code - put NullVal with BoolVal * Add support for `IN` keyword * Add GROUP_CONCAT keyword * Add COLLATE keyword From Claude: The test case demonstrates a simple use of COLLATE with a string literal, but in real MySQL queries, COLLATE is often used in more complex scenarios like: 1. String comparisons: `SELECT * FROM table WHERE name COLLATE utf8mb4_bin = 'John'` 2. Sorting: `SELECT * FROM table ORDER BY name COLLATE utf8mb4_unicode_ci` 3. JOINs: `SELECT * FROM table1 JOIN table2 ON table1.name COLLATE utf8mb4_bin = table2.name` The COLLATE clause is particularly useful when you need case-sensitive comparisons (utf8mb4_bin) or specific language-aware sorting rules.	4 months ago

Kyle Brandt	f4849eabc7	SQL Expressions: Change metric conversion to full long (#102728) ... When querying metric data (non-table data) with SQL Expressions, we need to convert the data to table format. This is alternative format which does not have the same issues with sparse data. There is now a __metric_name__ column and one __value__ column. Also a __display_name__ column if there is DisplayNameFromDS metadata. --------- Co-authored-by: Adam Simpson <adam@adamsimpson.net>	4 months ago

Sam Jewell	21b9d45ca6	SQL Expressions: Add CASE/WHEN nodes and fixes (and test) for functions just added to allowlist (#102040) ... * SQL Expressions: Add CASE/WHEN SQL nodes to allowlist * Fixed and test for functions added in #102011 * Add remaining functions to the test-case These are mostly aliases, so the LLM chose to omit them originally. But adding now for completeness * Fix ordering of allowed nodes	4 months ago
Sam Jewell	4bd5f29e05	SQL Expressions: Allow more functions (#102011) ... I used Cursor and Claude 3.7 thinking to expand the list of functions we allow. Specifically I needed `abs`. TODO: Check each of these in the official MySQL docs to ensure they are all safe: eg. this doc: https://dev.mysql.com/doc/refman/8.4/en/flow-control-functions.html#operator_case	4 months ago
Sam Jewell	7a3415148e	SQL Expressions: Add cell-limit for input dataframes (#101700) ... * expr: Add row limit to SQL expressions Adds a configurable row limit to SQL expressions to prevent memory issues with large result sets. The limit is configured via the `sql_expression_row_limit` setting in the `[expressions]` section of grafana.ini, with a default of 100,000 rows. The limit is enforced by checking the total number of rows across all input tables before executing the SQL query. If the total exceeds the limit, the query fails with an error message indicating the limit was exceeded. * revert addition of newline * Switch to table-driven tests * Remove single-frame test-cases. We only need to test for the multi frame case. Single frame is a subset of the multi-frame case * Add helper function Simplify the way tests are set up and written * Support convention, that limit: 0 is no limit * Set the row-limit in one place only * Update default limit to 20k rows As per some discussion here: https://raintank-corp.slack.com/archives/C071A5XCFST/p1741611647001369?thread_ts=1740047619.804869&cid=C071A5XCFST * Test row-limit is applied from config Make sure we protect this from regressions This is perhaps a brittle test, somewhat coupled to the code here. But it's good enough to prevent regressions at least. * Add public documentation for the limit * Limit total number of cells instead of rows * Use named-return for totalRows As @kylebrandt requested during review of #101700 * Leave DF cells as zero values during limits tests When testing the cell limit we don't interact with the cell values at all, so we leave them at their zero values both to speed up tests, and to simplify and clarify that their values aren't used. * Set SQLCmd limit at object creation - don't mutate * Test that SQL node receives limit when built And that it receives it from the Grafana config * Improve TODO message for new Expression Parser * Fix failing test by always creating config on the Service	4 months ago
Sam Jewell	0eafd0641f	SQL Expressions: Simplify test code (#101718) ... Simplify, by retaining quotes when escaping query We also don't need to convert to string when passing to fmt.Sprintf a slice of Bytes is accepted by Sprintf instead.	5 months ago

Kyle Brandt	4d7b9a3c77	SQL Expressions: Improve response to frame conversion handling (#100625) ... - use types.Convert to get a more normalized type returned from GMS. After syncing with GMS maintainers, the underlying type of the row could be different things (e.g. int when unit32, so this calls the Convert method from the GMS types library to normalize the interface. - Clean up fieldValFromRow more - Use IsText to capture different string types - Add more types to test, also update test to use same cmp.Diff method as others --------- Co-authored-by: Sam Jewell <2903904+samjewell@users.noreply.github.com>	5 months ago
