WIDTH_BUCKET
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The WIDTH_BUCKET() function divides a numeric range into equally sized buckets and calculates which bucket number a value is in.
SELECT width_bucket(0 , 0, 100, 10), width_bucket(15, 0, 100, 10), width_bucket(99, 0, 100, 10);
create.select( widthBucket(val(0) , 0, 100, 10), widthBucket(val(15), 0, 100, 10), widthBucket(val(99), 0, 100, 10)).fetch();
The result being
+--------------+--------------+--------------+ | width_bucket | width_bucket | width_bucket | +--------------+--------------+--------------+ | 1 | 2 | 10 | +--------------+--------------+--------------+
Dialect support
This example using jOOQ:
widthBucket(val(15), 0, 100, 10)
Translates to the following dialect specific expressions:
-- ACCESS SWITCH(15 < 0, 0, 15 >= 100, (10 + 1), TRUE, ((cdec((((15 - 0) * 10) / (100 - 0))) - ((((15 - 0) * 10) / (100 - 0)) < cdec((((15 - 0) * 10) / (100 - 0))))) + 1)) -- ASE, AURORA_MYSQL, BIGQUERY, DB2, DERBY, DUCKDB, EXASOL, FIREBIRD, H2, HANA, HSQLDB, INFORMIX, MARIADB, MEMSQL, MYSQL, -- REDSHIFT, SQLDATAWAREHOUSE, SQLITE, SQLSERVER, SYBASE, VERTICA CASE WHEN 15 < 0 THEN 0 WHEN 15 >= 100 THEN (10 + 1) ELSE (floor((((15 - 0) * 10) / (100 - 0))) + 1) END -- AURORA_POSTGRES, COCKROACHDB, ORACLE, POSTGRES, SNOWFLAKE, TERADATA, TRINO, YUGABYTEDB width_bucket(15, 0, 100, 10)
