mariadb-aggregate-functions
mariadb-aggregate-functions is a Databases & SQL skill for AI agents, published by mariadb-corporation in the mariadb-docs repository on GitHub. Skillspace rates mariadb-aggregate-functions D (68/100) and it passed the safety scan; the rating is based on static analysis only.
MariaDB aggregate functions — calculations across a set of rows (typically with GROUP BY or as window functions via OVER()). Covers counting (COUNT, COUNT(DISTINCT)), totals/averages (SUM, AVG), extrema (MIN, MAX), string aggregation (GROUP_CONCAT with DISTINCT/ORDER BY/SEPARATOR/LIMIT), bitwise aggregation (BIT_AND, BIT_OR, BIT_XOR), and the statistical family (STD/STDDEV/STDDEV_POP, STDDEV_SAMP, VARIANCE/VAR_POP, VAR_SAMP). Use when summarizing or rolling up rows in MariaDB. Note aggregates skip NULLs, GROUP_CONCAT silently truncates at group_concat_max_len, and ONLY_FULL_GROUP_BY is not in the default sql_mode.
